The structure of the second floor of the dungeon is similar to that of the first floor, except that the gravel and cracks on the stone walls can be clearly seen on this floor.

There was a major earthquake here more than ten years ago. Although the buildings outside have become dilapidated, the palace is basically intact. Lin An thought that the underground city would not be too affected.

But now we can see scattered stones and gaps in the wall. It seems that the damage will become more serious as you go down.

Lin An's expression was indifferent, but the hand he held became harder and harder.

Shen Xiuze walked aside, glanced at Lin An, who was anxious in his heart, and asked, "Do you know how many floors this dungeon has?" "Hmm? It

should be nine floors." His thoughts came back instantly, Lin An An looked up at the depressing and narrow corridor and replied.

"I heard from people in Muling City that there is a mechanism here, but we have never encountered it before." Shen Xiuze looked around and didn't know where the mechanism would be, but the underground city was abandoned. It's been a long time, and the mechanisms inside are probably broken.

Lin An didn't know where there would be a mechanism. The map only showed the general direction.

Soon, they found a skeleton in the middle of the second floor. The clothes on the skeleton were very modern, and it was most likely the person who entered here more than ten years ago.

When he saw the skeleton, Lin An's steps slowed down and his body became stiff.

Shen Xiuze knew that he was afraid, afraid that the corpse would be the person he wanted to find, so he let go of his hand and stepped forward to take a closer look.

"The clothes were a popular style among explorers more than ten years ago, but there was a knife on the side. This kind of knife was specially customized. Every explorer's knife is different, so this is an explorer. The cause of death is unknown." Shen Xiuze analyzed calmly and found that the cause of death could not be determined from the skeleton. Although the clothes had become shabby, they were not damaged, indicating that the explorer did not die of trauma.

His parents were history students, not explorers.

After confirming the identity of the skeleton, Lin An stepped forward and squatted next to Shen Xiuze.

Shen Xiuze stepped forward to identify Lin An in order to make Lin An feel at ease. In fact, he still had some things he had not said.

Generally, when an explorer dies, his companions will take his body out and bury it, but this body fell randomly in the middle of the second floor, indicating that other people no longer cared about the explorer at that time, and the body was not there. The burial was probably because no one came out.

These were just Shen Xiuze's guesses. He did not tell Lin An. After all, Lin An was already very nervous. If he knew this, it would only make him more anxious.

Later, on the second floor, they discovered several more skeletons one after another, all of which belonged to explorers. The cause of death was also unclear.

So how did they die?

There was silence all around, except for the sound of their own footsteps.

Continuing to walk forward, a rustling sound suddenly came from behind. The sound was very faint, but it was extremely clear in the ears of the two people with superpowers.

At the same time, he turned to look at the source of the sound. From the gaps in the wall behind him, many black bugs were crawling out one after another. These bugs were very small, only the size of a grain of rice. They were connected head to tail and crawled towards them on the wall.

There is a small white dot on the back of the black bug, which looks like eyes, which is particularly eye-catching.

This is a rare type of tick. Unlike other ticks that like to suck blood and live as parasites, this white-spotted tick unique to the depths of the forest is highly venomous and a single bite will be fatal.

So those who died were poisoned by tick bites?

More ticks poured out from the cracks everywhere and headed towards the two of them.

Although their special powers can easily kill ticks, no one knows how many there are here. Look, these ticks are crawling out continuously, or is it better to get rid of them as soon as possible.

The two looked at each other, and Lin An led the way, running towards the passage down to the second floor.

While they were escaping, a large number of ticks continued to emerge from the gaps in the stone walls along the road. As Shen Xiuze ran, he burned the ticks on both sides and behind him with fire.

These ticks all have wings, and when alerted, they immediately flap their wings and fly around.

The ticks behind and on both sides were dealt with by Shen Xiuze, while the ticks that came towards him were covered by Lin An with layers of water mist. As long as their wings were stained with water, these ticks would not be able to fly.

The two of them didn't say a word the whole time, but they cooperated very well. They reached the passage going down to the second floor.

The passage on each floor is a circular passage similar to a shaft. The steep steps next to it must be climbed with both hands to go down.

Lin An was the first to go down without any hesitation, and Shen Xiuze followed closely behind.

Behind him, ticks kept coming from the air and the ground, but when they passed through the passage, the entrance of the passage suddenly ignited with flames, covering the entire entrance.

The ticks that tried to pass through the passage were burned to death and fell down with a burning smell.

The remaining bugs also stayed away and did not continue to catch up.

The third floor of the dungeon.

The two of them were even more cautious, but no corpse was seen on this floor. They walked through the corridor and around the hall. They walked slowly, but they met at the same time in a straight corridor with round arches. I stepped on a loose stone slab.

Shen Xiuze immediately noticed that something was wrong. This underground city looked more like it was dug out of a huge stone. How could there be a stone slab?

He looked along the stone slabs under his feet and found a huge round stone at the end of the corridor. The stone was about the same size as the corridor they were in. At this time, the stone was shaking slightly back and forth.

"What's going on?" Lin An also noticed something unusual.

Both of them were actually very sensitive to danger and stopped when they noticed something strange under their feet.

"The stone slab under our feet extends to the end of the corridor, and the stone at the end is now being pried. As long as we move a little, the stone will roll over." This corridor

shows ?Domed in shape, there are no stone houses or depressions on both sides. If the stone rolls over, they will not even have a place to hide.

"Behind the stone, there is a passage." According to the mark on the map, behind the round boulder is the entrance to the next level. Lin An was sure, but how to move the stone and walk over now was a problem.

"I'll give the signal later, and we'll run back together toward the corner." Shen Xiuze glanced at the road behind him. In fact, they were still more than ten meters away from the corner, and the stone in front was only three meters away. Meters, two legs cannot be faster than the stone, so they need to set up some obstacles to block the speed of the stone.

Shen Xiuze took off metal blocks from his wrists, waist, and legs. These metals were all worn just in case.

Just enough to make some obstacles.

The metal was manipulated to change shape, and finally turned into roadblocks of different sizes and heights, which were placed everywhere on the ground.

The two of them withdrew their feet at the same time, turned around and ran back, and the huge stone immediately rumbled towards them.

In this moment of competition for speed, Lin An, a zombie with slow speed and poor physical strength, suffered a great disadvantage. He slowed down after running a few steps.

If the round stone behind him hadn't been blocked by a metal obstacle, it would have crushed Lin An into a zombie cake.

Lin An worked hard, but he really couldn't run fast.

Shen Xiuze kept the same pace as Lin An. Even if he deliberately slowed down, he found that Lin An still couldn't run fast. In the end, he could only pick him up and carry him seven or eight meters ahead. Run around the corner.

The boulder was chasing them closely. This corridor was not only about the same size as the boulder, but also had a certain slope. The rolling boulder was about to crush the two of them.

Lin An knew that he was holding him back. If Shen Xiuze had left him alone and ran backwards at full speed, he would have reached the corner long ago.

In the midst of lightning and flint, Lin An raised his hand and used his supernatural power. A large amount of water rushed towards the stone at high speed, slowing down the speed of the boulder.

Finally, he ran to the end. Shen Xiuze turned sideways and stood at the corner of the end. The boulder rushed towards the stone wall. The stone wall and the stone collided with each other, making a huge sound. Even the surrounding walls were shaking, which showed the impact of the impact. How powerful it is.

The boulder stayed in place after the impact, and also blocked most of the corner. Fortunately, there was still a gap for one person to pass, otherwise they would not be able to move forward at all.

Shen Xiuze put Lin An down: "Are you okay?"

Lin An nodded. During this period of time, walking in the forest made his physical strength slightly better. Otherwise, he would be tired after just a few steps. panting.

He looked at Shen Xiuze across from him. He was running so fast and still wanted to hug him, but it seemed that he was not affected at all, and even his breathing was not disturbed.

Lin An envied the other party. If he had such good physical strength before, he could defeat those who bullied him: "Your physical strength is so good."

Shen Xiuze paused and looked at Lin An. An's eyes curled up with pure envy: "Thank you for the compliment, your physical strength will get better in the future."

"I can't do it." Lin An admitted simply.

Not to mention that he is a zombie now, and I don't know if he can change back in the future. In fact, his body has been like this since he was a child. He can't run fast or walk. He also often gets sick. Every time he catches a cold, he is the first one. He fell down, so the teachers at the orphanage were impatient to take care of him, a person who was often sick.

It is estimated that it is unlikely to get better in the future.

"Don't worry, if possible, I will help you exercise in the future." Shen Xiuze touched his head and did not continue the topic, but tried to pass sideways through the gap between the boulder and the corner.

Seeing such a scene made Lin Anxin tremble with fear. After all, if the boulder had shaken just a few more times, Shen Xiuze would have been crushed to death.

But in the end, I managed to put it through reluctantly, but the clothes on my chest were covered in a lot of dust.

Lin An, on the other hand, was very relaxed and passed by in a blink of an eye.

He was much thinner than Shen Xiuze, and Lin An could easily get through the gap where the opponent barely managed to get through.

After walking through this corridor again, the two of them saw the place where the boulder had been. Behind them were two bones that had become crushed. They could not see it until they were blocked by the boulder.

Shen Xiuze restored a large pile of flattened metal on the ground to its original shape and put it into pockets everywhere on his body. He did not have spatial powers, so the existence of these metals was very important. He must use some and less. Recycle.

The passage to the next level is behind the boulder, right next to the two skeletons. Shen Xiuze also carefully confirmed that the two skeletons were not Lin An's parents.

The overall layout of the fourth, fifth, and sixth underground floors is similar to the floors above. There are also corpses of various agencies and explorers inside. As more and more corpses are encountered, Lin An His face became more and more solemn.

He knew that after so many years, his parents should be gone, but he still held on to the last hope in his heart. The fact that he had not seen a body meant that they still had the possibility of survival. But as they walked together more than ten years ago, The corpses of explorers kept appearing, and his hope became increasingly slim.

On the sixth underground floor, Lin An took Shen Xiuze for a long time, but could not find the passage down.

The map on the stone gate of the palace is flat, and many routes inside are overlapping. The first five floors went smoothly, but on the sixth floor, they searched everywhere but could not find the entrance to the lower floor.

"It may have been hidden. It is impossible for the ancient Maus people to show all the maps of the underground city. They will definitely have some reservations. We are lucky to have come here safely. The next step is You can only look for it on your own." Shen Xiuze consoled him.

Lin An closed his eyes. He was indeed a little too impatient.

There must be a way to get down to this level. According to the information left by mom and dad, there are nine floors in Mowus City. They must have overlooked something.

Along the way, Shen Xiuze didn't find any clues about the passage. He thought about the floors he walked through. It seemed that the deeper he went down, the more obvious the traces of damage from the earthquake that year were. So could the entrance disappear in the earthquake? ?

He told Lin An his idea, and Lin An also thought it was possible, but now there were scattered stones in many places on the sixth floor, and it was impossible to determine the location of the entrance.

Do you want to search again?

Lin An felt that if he searched again using ordinary methods, he would get the same result.

He suddenly looked up at Shen Xiuze, his eyes shining: "I have a solution."

A light mist filled the sixth floor of the dungeon, as if white gauze was lingering in all kinds of walls, gaps, and corners. , all places are invaded by water mist.

Lin An closed his eyes and carefully felt the touches coming from everywhere. He seemed to have turned into mist, filling every corner.

"Found it!" Lin An opened his eyes.

You can't see the way down with the naked eye, but the water mist can find the space below through the narrow gap. After all, the air circulates. As long as you find a place where the air can circulate, there may be a passage on the lower floor.

Lin An found three places in total, and the one closest to them was in the lobby on the sixth floor.

There is a stone pillar in the middle of the hall. There is no decoration or carving on the stone pillar, it is plain and simple.

But the air flow that Lin An felt came from the top of the stone pillar.

This stone pillar is not used to support the top. There is still a little distance between it and the stone wall at the top. It is just used to confuse outsiders.

After walking around the stone pillar twice, Lin An knocked on the stone pillar and found that it was hollow inside.

The sound of knocking is very clear, indicating that the surface of the stone pillar is very thin.

Lin An felt that he could break the stone pillar directly. He clenched his fist and punched the stone pillar hard.

There were no gaps in the stone pillars. Lin An held his fist with his other hand and stood silently aside.

He overestimated himself, and his hands hurt.

Before Shen Xiuze could stop him, he saw the other party hammering at the stone pillar without hesitation.

He looked dumbfounded as Lin An held on to hold his hand, looking extremely patient.

"Although it sounds very brittle, the stones here are very hard. Even if there is only a thin layer, they cannot be broken easily." After saying this, Shen Xiuze punched the stone pillar at random, and the stone pillar suddenly cracked into cobwebs. like gaps.

Lin An stared at the other person with wide eyes, marveling in his mind at how hard Shen Xiuze's fist was, and the next second he saw him retract the metal covering the back of his hand.

Lin An: "..."

Well, he was really stupid to hit the stone pillar with his fist.

The two peeled off the surface of the stone pillar along the cracks, and sure enough they saw a circular cave at the bottom. The cave was highly tilted, and it looked uneven, surrounded by circles of rounded stone layers.

Just as Lin An was about to stop, he was stopped by Shen Xiuze.

"I'll go down first." You

can't see the bottom from here, and you can't be sure whether there will be any danger, so Shen Xiuze went down first. The cave was tilted and he couldn't stand, so he could only sit down and slide down slowly.

The two slid down the cave for a long time, and finally saw the exit.

But what is surprising is that there is light at the exit.

They have obviously gone deep underground, and the first six floors are extremely dark. Both of them can walk freely in the dark environment because of their strong night vision, but why is there light below?

The light is even very bright and dazzling, like the sun outside.

Faced with this situation, Lin An couldn't give an explanation. After all, the seventh, eighth, and ninth floors of the dungeon were also unknown areas for him.

Shen Xiuze continued down and finally came out of the cave entrance.

The dazzling light made it difficult for the two people who were already familiar with the darkness to open their eyes. After adapting to the light here, the picture that appeared in front of them made them both begin to wonder if it was an illusion.

"Is this a dungeon?" Shen Xiuze's tone was full of suspicion. He even felt that they had gone outside.

Lin An looked at the dream-like scene in front of him and murmured: "This is the real Mouse City."

Each of the first six floors is only about two meters high, and where they are now? , it is hundreds of meters high, and a building similar to a pyramid stands in it. Its scale and grandeur are amazing. And around that building, there are stone houses similar to the ones outside. , but the stone houses here are much better than the broken stones and ruins outside, whether in terms of completeness or newness.

There are even various plants growing all over the stone house and on the ground.

What puzzled Lin An the most was the light source here. The extremely high stone wall ceiling was covered with colorful patterns. The patterns were bright and bright. Even after thousands of years, they were still intact and lifelike.

In the center of the ceiling, there is a very obvious light source. The light source is too far away and too bright to see what it is made of.

But looking up from below, it looks like a small sun hanging high above it, illuminating everything in this space.

Could it be that the light bulb had been invented in the city of Maus thousands of years ago?

Lin An's head was filled with questions.
