bite! You lost [Energy Cores]*50,000, [Steel]*5 tons!

Congratulations, you have obtained [Automatic Guard Tower]*100, which has been stored in the storage space!

Zhang Chen traded the [Automatic Guard Tower] to Isaac, who immediately placed 9,500 crystal cores on it.

Both parties click OK.

Deal Done!

Isaac was so happy when he saw the 100 [Automatic Guard Towers] in his storage ring.

He went outside and found an alley where the zombies were gathered.

Two automatic sentry towers were installed at the entrance of the alley.

Then have Bazel play the role of a naked survivor running away in an alley, chased by a group of zombies.

In the end, more than a hundred zombies on one street were easily eliminated by the [Automatic Warning Tower]!

Isaac sent the video to the markets and salespeople he developed in various cities.

Keep them on continuous rotation on regional channels.

Anyway, advertising in the apocalypse doesn’t cost money, so it would be a waste not to flood the screen with ads!

Soon, the order came!

It is a survivor camp trapped in a tide of zombies.

They were the most unlucky as they were surrounded by a tide of zombies while sleeping at night.

It was impossible to see the road clearly in the dark, and it was even more difficult to avoid the zombies' sneak attacks, so it was impossible to retreat.

By the time daybreak came, they were completely trapped where they were.

Now they have been trapped for 2 days, although there is plenty of food.

But there are too many zombies and I can’t kill them all, so I can forget about upgrading and becoming stronger in the next few days.

And who knows if these zombies will become even more terrifying after the 30th day? !

So the camp spent a lot of money, paid 1,500 crystal cores, and bought 10 [Automatic Warning Towers]!

The cross was sold easily.

This made Isaac's confidence swell a little.

Directly raise the price to 180 crystal cores per unit!

Fifteen more were quickly sold.

The price was raised again to 200 crystal cores per unit...

and the orders continued to flow in.

Isaac's network of contacts covers more than a dozen nearby cities, and his sales scope is quite wide.

Before Isaac could raise the price further, all 100 [Automatic Guard Towers] had been sold out.

The subordinate sales staff kept urging Isaac to ship the goods.

The price of a sentry tower in some areas has been driven up to 280 crystal cores.

However, there is a situation where there is a price but no demand.

"Mr. Zhang...are you there?"

Isaac's flattery could be felt even through the screen.

"Speak!"

Zhang Chen replied simply.

"Well... let me ask, if there is a 95% discount on 100 planes... then how many planes can get a bigger discount?"

Isaac asked cautiously.

"For orders over 300 planes at a time, there's a 10% discount. This is the highest discount!"

Zhang Chen replied.

When I saw Isaac asking this, I knew that the 100 planes had been sold and that the demand was exceeding supply in the market!

"300 planes... with a 10% discount, one plane is 90 crystal cores, a total of 27,000 crystal cores..."

Isaac calculated to himself.

I just sold 100 planes and now have 17,500 crystal cores.

We have to find a way to get another 10,000 crystal cores!

He immediately targeted those buyers who were eager to make a purchase, offering a discount of 10 crystal cores on the price of goods after payment. Relying on Isaac's good business reputation, he collected all the payments in advance.

"I'm buying... 400 this time!"

Isaac directly took out 36,000 crystal cores and clicked the transaction.

Zhang Chen made another 400 [Automatic Guard Towers] and traded them to Isaac.

Transaction successful!

At present, Zhang Chen has consumed a total of 250,000 crystal cores in building the sentry tower and earned 45,000 crystal cores from transactions.

Only tens of thousands of the more than 200,000 crystal cores are left.

However, the growth rate of the number of crystal cores in the lower right corner began to increase rapidly.

At first, only the ones and tens digits kept changing.

It soon turned into hundreds, and occasionally it would jump to thousands.

Hundreds of crystal cores are received almost every second.

And this is the result even though the 400 [Automatic Guard Towers] that were just sold have not yet been put into operation!

These 400 planes should be enough to keep Isaac busy for a while.

Zhang Chen took out a villa on the top of the mountain in the park.

Then sit on the second-floor terrace and look down.

There are sweeping views across the Farm Park and surrounding streets.

Hundreds of people are working with clear division of labor.

Some people are responsible for fertilizer synthesis, while planting, fertilizing, and harvesting are all handled by different people.

The planting time for each field is staggered by one hour.

Just as I have finished planting here and harvested the land next to it, I can continue planting in the land next to it.

By taking turns to farm, efficiency is greatly improved.

In a trance, Zhang Chen felt as if he had returned to the ancient farming era.

It's rare to enjoy a quiet afternoon.

Zhang Chen fried a few large chicken fillets, French fries and squid rings, and put cheese slices and tomato sauce on them.

Hiss...

it’s really delicious!

Now this kind of high-calorie food is the most anti-hunger, and you don’t have to worry about gaining weight, you can eat as much as you want.

Because once you eat less, you may be hungry again after a while.

After dinner, Zhang Chen took out an ice cream and started eating it happily.

This is life in the end times... simple and comfortable...

Zhang Chen subconsciously looked at the total number of energy crystal cores.

When the wall was built, the total number was still over 50,000.

Up to now, less than an hour has passed, and the total number has increased to more than 270,000.

I have already made back my investment and even made a small profit.

From now on, all future income will be net profit!

Zhang Chen was in a good mood and took inventory of the skills and items he had used to kill S13 and others recently.

[Rare skill: Anti-gravity flight], [Rare skill: Deadly charm], [Rare skill: Equipment enhancement]...

When Zhang Chen saw the third skill, his eyes lit up!

[Rare Skills·Equipment Enhancement]: By decomposing energy weapons and rare weapons, there is a certain probability of extracting special attributes from them, and the attributes can be integrated into new equipment.

Zhang Chen also has a skill called [Rare Skill·Blueprint Optimization]. It's a pity that this optimization can only optimize weapons and equipment to rare. 30 days before the end of the world, apart from the only one, rare is the strongest.

However...

Zhang Chen felt that his Thousand Bone Sword could be strengthened further.

In fact, both the Thousand Bone Sword and the Seven-Colored Sword are rare weapons, but the latter one is too flashy.

Zhang Chen felt that carrying such a weapon was not majestic enough and it destroyed the originally solemn and tense atmosphere.

Then disassemble the Seven-Colored Sword and strengthen the Thousand-Bone Sword!

The moment Zhang Chen focused his attention on the [Rare Seven-Colored Sword].

The prompt appeared again in time:

[Please note that there is only a 25% chance of obtaining skills by decomposing the colorful sword, and a 3% chance of obtaining all the above skills! 】
