has a helicopter, so it’s hard to go too fast!

When the first ray of sunlight rose from the horizon...

the helicopter followed the markings on the small map and successfully arrived at the roof of Shannan Central Hospital.

There is no helipad here, but fortunately the space is relatively open.

Can also stop and get off the helicopter.

Got off the plane.

Er Pang sat obediently in front of Zhang Chen, stuck out his tongue and licked his pants.

"Oh, you're hungry, aren't you!"

Zhang Chen then remembered that he hadn't fed Erpang for more than ten hours.

This time he directly took out [Rapid Fertilizer].

10 [mutated fertilizers] are synthesized into one [accelerated fertilizer].

10 [Accelerated Fertilizer] are synthesized into one [Quick Fertilizer].

[Rapid Fertilizer] is the highest level at the current stage.

Only after the suppression is lifted can higher-level fertilizers be synthesized.

This is delicious for Erpang!

The two fat men buried their heads in their mouths and started eating.

Today is the twelfth day of the end of the world.

Zhang Chen made a portion of self-heating rice.

I sat on the roof and started eating.

Underfoot, the black masses of ordinary zombies were slowly fading away.

Only then did Zhang Chen remember.

According to the video, the laboratory under the hospital was evacuated urgently because it was besieged by zombies.

These zombies surrounding the hospital building must be the zombie wave at that time!

Zhang Chen took a quick glance.

There are five buildings in the entire hospital.

There is an outpatient building, an emergency building, and the remaining three are inpatient buildings.

My current location is on the roof of the outpatient building.

These five buildings were surrounded by dense zombies.

The hospital yard is also full of zombies.

Look further away.

Several blocks are also full of chaos.

This formation was no less than the tide of corpses encountered in Jiangbei before.

The ordinary zombies around the clinic building felt the pressure of Er Fat.

They all receded in all directions like an ebbing tide.

One after another, countless zombies poured out from the door of the outpatient building.

A full twenty minutes later.

Then no zombies ran out again.

Soon, an ordinary zombie vacuum area with a radius of about 100 meters was left around the clinic building.

There were only a few crawlers, still clinging tirelessly to the wall outside the hospital building.

A giant tank stood blankly at the door of the building.

Next to it, there is a tank with a bent barrel.

Zhang Chen looked down at the hospital building.

Soon, a prompt also appeared:

[There are five creepers and one poisonous insect breeder in this building. They do not pose any threat to you! 】

Hmm...

Actually, even if the giant tank is in front of Zhang Chen, it still does not pose a threat.

If no mutated type IV infected people appear in the current stage of the world...

there will be no monsters that can pose a threat to Zhang Chen!

"I just don't know where the entrance is to the laboratory on the seventh floor underground!"

"It's definitely not as simple as taking the hospital's passenger elevator down!"

"The previous furniture store had a backup power system... I hope this hospital will also Could there be..."

Zhang Chen thought wildly in his mind.

The prompt will only appear when you stare at a certain place.

Therefore, it is impossible to answer questions such as "Where is the entrance to the underground laboratory?"

Zhang Chen could only look for it bit by bit.

It’s really a bit troublesome!

But...

before looking for the entrance...

Zhang Chen looked at the tide of corpses around him.

Can't waste it!

After eating, Zhang Chen jumped off the roof with Er Pang.

When it landed, it directly used the force of the fall to split the giant tank in two.

Then, the huge body of the giant tank turned into a ball of mist and disappeared!

Next up are these creepers.

Zhang Chen waved the Thousand Bone Knife and cut them into pieces with a few casual moves.

Before the minced meat could hit the ground, it also turned into mist and dissipated in the air.

Zhang Chen then grabbed the hair of the poisonous insect breeder.

——There is no way, this guy's body is covered with mucus and is too slippery to be grasped.

He threw it forcefully into the tide of corpses.

Then he took out his assault rifle and fired twice.

Phew!

The poisonous insect breeder's venom-filled belly exploded above the corpses.

Countless venom splashed on the zombie's head.

Soon small holes were corroded.

Some zombies had their heads corroded directly.

Together with the Poisonous Insect Breeder, they turned into clouds of mist.

Ordinary zombies, under the pressure of Erpang, would not dare to take an extra step this way even if they heard the gunshot.

Instead, the creepers and giant tanks in the distance were attracted by the gunfire.

He rushed over like crazy.

The creepers rushed over the zombies' heads quickly.

The long claws can be used to grab at will.

The zombies below must be covered in flesh and blood.

Some even had their skulls opened directly.

He fell straight to the ground.

Not to mention giant tanks.

They were trampled all the way through the tide of corpses.

There were bursts of spooky bone-breaking sounds.

All the zombies in front were trampled to pieces with broken bones and bloody flesh.

What a disaster!

"Just in time!"

Zhang Chen smiled slightly.

Now there are more than twenty creepers and seven or eight giant tanks rushing towards him.

And it looks like they might arrive at the same time!

Zhang Chen held the Thousand Bone Knife and stood calmly in front of the tide of corpses.

Close!

Closer!

Just when the creepers jumped up and the giant tanks raised their fists, they all hit Zhang Chen.

The latter suddenly waved his arms!

[Crystal Nucleus Resonance]!

Buzz...

boom!

The surrounding creepers exploded one after another, turning into a ball of white mist and disappearing.

There were fifty or sixty ordinary zombies nearby, and they vaporized instantly!

Giant tanks are more resistant to beating.

Although he was shocked, he only lost about 20% of his tissue and he was still alive.

[Crystal Nucleus Resonance]!

Zhang Chen started again.

Phew!

This time the giant tank slowly dissipated, and the ordinary zombies that had just rushed up around it were vaporized again.

But soon, they filled up again.

It was as if there was an invisible wall that kept them in place, and they did not dare to cross the thunder pool even half a step.

"Let's exercise here first!"

"We have business to do later, so we can't waste all our energy here!"

Zhang Chen reached out and took out the [Automatic Guard Tower].

One is installed at the front door and the back door of the outpatient building.

As soon as they were installed, they started working in earnest.

Bang bang bang bang!

Energy balls flew out one after another.

Explodes the heads of ordinary zombies.

At the same time, the number of energy crystal nuclei on Zhang Chen's interface began to slowly increase.

Automatic hang-up artifact!

"Wuwuwu...wuwuwu..."

Suddenly, a burst of crying came.

Zhang Chen raised his head.

I saw a wailer appearing on the roof of the building at some point.

A faded red string is tied around the left wrist.
