Global Cataclysm: Infinitely Upgrade Shelter

March 16.

Nearly a month has passed, and during this month, the shelter and the weather around the shelter have basically been the same, and there have been no particularly dramatic changes.

The weather is still hot, and two rounds of the sun are seen in the sky from time to time.

And the time for the two suns to appear is constantly increasing.

This is not a good thing for humans on Earth at all.

The hotter the weather, the harder it will be for the average person on the planet to survive these weathers.

In fact, only when the weather returns to normal and various disasters gradually decrease, can human beings develop better, resist catastrophes, and protect their homeland.

Human willpower is very strong, and human beings often burst out with very amazing willpower in the face of various disasters.

Although there are many disasters, humanity is still very strong.

After nearly a month of construction, about 1/10 of the underground market was built.

In fact, this speed is already very fast, far beyond Zhao Chen's expectations.

The underground trading market built by Zhao Chen is very large with 263, and it is no exaggeration to say that it can accommodate more than 100,000 people to trade at the same time.

The most fundamental reason why Zhao Chen at least established such a huge underground trading market is that he is very ambitious.

Zhao Chen has a lot of ideas in the future.

He didn't just want to be strong, he didn't just want to keep himself alive.

Zhao Chen has even greater ambitions.

He has a lot of ideas...

Zhao Chen took a deep breath, and he walked out of the shelter.

After a month of accumulation, Zhao Chen has accumulated more than 3,000 survival points.

Coupled with the rewards of some daily tasks, Zhao Chen gained a total of more than 5,000 survival points.

These survival points, coupled with the previous reward of 10,000 survival points, Zhao Chen is almost enough, and the basic requirements for building a neutral survival point are enough.

It's just that if Zhao Chen wants to build a gravity field, he needs some other things.

Now Zhao Chen has not gathered enough raw materials, only after all the raw materials are gathered, Zhao Chen can have basic raw materials and be able to build a gravity field.

Qiao Qian is still arranging the employees of major manufacturers and major manufacturers, and is constantly working hard to train (BCEH).

In addition to these daily trainings, Zhao Chen is ready to proceed from reality and enhance their strength.

That's right, Zhao Chen is going to equip them with weapons.

It's just that Zhao Chen is not ready to equip them with thermal weapons.

Although the current employees are the same group as Zhao Chen, Zhao Chen does not dare to guarantee whether they have the intention of rebelling after a long time.

If Zhao Chen directly equips them with thermal weapons, it is most likely to pose a deadly threat to himself.

A lot of things need to be developed step by step.

As the saying goes: the road knows the horsepower, and the people will see it for a long time.

However, it is impossible for Zhao Chen not to equip them with weapons. If Zhao Chen didn't equip them with weapons, their combat effectiveness would not be improved, and they would not be able to provide enough help to Zhao Chen when they encountered various disasters in the future.

Zhao Chen needs to provide them with weapons, but Zhao Chen can't provide them with weapons that can hurt themselves.

These weapons provided by Zhao Chen should not only enhance the employees of major manufacturers, but also their technical strength.

Moreover, it is necessary to prevent Zhao Chen from causing a particularly huge threat within a controllable range.

Both of these points need to be controlled by Zhao Chen personally.

Come to think of it, the lethality of ordinary cold weapons is too small and does not have much effect. (If you read a violent novel, go to Feilu Novel Network!)

Hot weapons Zhao Chen didn't think about it at all, since this is the case, Zhao Chen is ready to create some cold weapons with super lethality for the employees of major manufacturers.

Even to a certain extent, these cold weapons are not inferior to thermal weapons at all.

The cold weapons that Zhao Chen wanted to create were not other cold weapons, but crossbow arrows.

That's right, what Zhao Chen is going to build is a crossbow arrow.

The lethality of conventional cold weapons is too small, and it does not have a particularly huge effect on Zhao Chen.

Meantime.

The lethality of thermal weapons is too huge, and the raw materials are particularly scarce, Zhao Chen is difficult to control, and it is not suitable for the weapons that match his current development stage.

The reason why Zhao Chen created crossbow arrows was not only because crossbow arrows would have a basic lethality guarantee. At the same time, compared to guns and ammunition, Zhao Chen is easier to control.

After combining these advantages, this is also the fundamental reason why Zhao Chen is particularly relieved to use crossbow arrows.

If it is replaced by some other weapons and equipment, Zhao Chen may not be at ease in his heart, but now after changing to crossbow arrows, he is particularly relieved in his heart.

Zhao Chen chose to build crossbow arrows, and he also had a particularly huge advantage, that is, a military-grade 3D printing machine.

Generally speaking, as long as it is not particularly complicated equipment, Zhao Chen can easily print it out with a military-grade 3D printing machine.

With a printer, Mack Cloud can quickly produce crossbow bolts in large quantities.

Using the printer to print directly software can not only save Zhao Chen a lot of costs, but also just make the printer come in handy.

In fact, Zhao Chen has not used the printer directly for a long time, and the printer is equivalent to a placed item in his platform manual.

As for what kind of raw material the crossbow arrow needs to be printed now, Zhao Chen has not yet thought about it in his heart.

It's just that no matter what kind of material it is, Zhao Chen's most basic conditions need to be met.

First of all, it must be the level of tenacity.

Bows and arrows are different from other weapons in that they are easy to destroy. When Zhao Chen uses a printer to print workpieces, he needs to give priority to the raw materials of the workpiece itself, so as to enhance the toughness.

In addition to tenacity, another important indicator is toughness, in other words, the ability to eject.

If a crossbow bolt is not good at catapulting and is not lethal, it will not be of much use.

Only when these two are present at the same time can they play their due role.

On the second day, Zhao Chen had just woken up when he heard the sound of the system prompt.

Today, in addition to Qiao Qian coming over to exercise in person, Zhao Chen also accompanied them to exercise.

When Zhao Chen was resting, he said directly: "You have been training hard in the past few days, and I have also prepared some special gifts for you here as a special reward, I hope each of you likes it." "

As soon as the words fell, Zhao Chen took out the crossbow arrows prepared by his grandfather.

When they saw the crossbow arrow in front of them, everyone was very excited, but no one said anything.

Zhao Chen took the crossbow arrow and pulled the crossbow arrow at a position in front of him, and the crossbow arrow quickly ejected out.

“biubiubiu"

The lethality was terrifying, and the audience shook.
