Global Cataclysm: Infinitely Upgrade Shelter

For Zhao Chen, this is indeed a particularly troublesome matter.

Fortunately, this troublesome matter is under control.

If there was more than one tire that exploded, it would be difficult to deal with.

After the tire exploded, Zhao Chen and Qiao Qian spent 10 minutes with the repair tools, and finally ~ replaced the tire.

Although the spare tire in the back has been changed, the spare tire, after all, is smaller than the actual tire, and when Zhao Chen is driving, the overall driving comfort is not as good as before.

Zhao Chen had encountered roadblocks many times before, but when facing these roadblocks, there were basically no dangerous incidents in front of him.

The occurrence of such a dangerous incident this time reminded Zhao Chen that Zhao Chen must pay attention to this kind of thing.

How to deal with it to avoid this kind of thing perfectly, Zhao Chen couldn't help but think about it in his mind.

It seems that the only way to essentially improve the defense of the tires is to improve them.

The jeep in front of me is easy to solve, the tire is broken, just change the tire.

But if the tires of a large transport car and Zhao Chen's large RV are broken, there is no extra tire to replace.

This is also the fundamental reason why Zhao Chen was reluctant to drive directly when he encountered roadblocks before, even if he chose to take a detour for a longer distance.

In Zhao Chen's heart, the priority of large RVs is greater than that of large transport vehicles and jeeps.

In this case, the only way to start is to improve the defensive attributes of the tires.

So, Zhao Chen directly recited silently in his mind: "System, check the upgrade conditions of the tires." "

[After system testing, the current tire is an ordinary tire.] The wear resistance of ordinary tires can reach 10,000 kilometers, which cannot prevent other complex road conditions. Upgrades are available: shock-absorbing anti-skid tires. 】

[Shock-absorbing anti-skid tires: As the name suggests, they have good shock-absorbing and anti-skid functions. Once driving, you can freely shuttle through the mountains with various road conditions. But it can't cope with extreme road conditions. Survival points to consume: 200. 】

[Polymer wear-resistant tires: Polymer wear-resistant tires can greatly improve the wear resistance of tires, even if you use a dagger and slide on the polymer wear-resistant tires, you can't cause damage to the tires. Survival points to consume: 200. 】

[Metallic inner wire mesh polymer shock-absorbing anti-slip wear-resistant tire: The inside of the tire is a metal mesh structure, which can not only adapt to a variety of road conditions, but also improve its solidity by more than 30 times. The use of this tire can be used in a variety of complex road surfaces, but also can adapt to a variety of extreme road conditions. Requires cost of survival points: 800. 】

After Zhao Chen looked at the three upgrade directions, he suddenly hit the last one.

Previously, Zhao Chen's large RV had undergone a round of upgrades, and the tires already had good defensive attributes, but vehicles such as large transport cars had not undergone a new round of upgrades and did not have particularly strong defensive capabilities.

When Zhao Chen was ready to go back, he would upgrade the large transport vehicle again, so that it would have strong defensive capabilities to adapt to various road conditions.

In terms of maintenance alone, whether it is a large transport car or Zhao Chen's large RV, it is relatively difficult to maintain.

Zhao Chen will focus on upgrading these two cars.

Others can be moved back a bit.

When Zhao Chen and Qiao Qian came to the cave, they checked all the caves, but fortunately there was no fire.

In fact, there are no extra weeds in the outermost part of the cave, and Zhao Chen does not have to worry about a fire in this circle around the periphery.

In addition to the outer circle, a little further into the underground river, the underground river, the surrounding area of the underground river, although the overall air is not particularly humid, but in general there will be no fire.

Although there are many fruit trees in the cave, these fruit trees are within Zhao Chen's control, and Zhao Chen will also transport a large number of these fruit trees and plant them in various places in the near future.

The only thing Zhao Chen was worried about now was the other side of the cave.

On the other side of the cave, there is a ready-made ecosystem with not only bushes, but also a variety of flora and fauna.

If there is a fire on the other side, the impact on the entire ecosystem is very huge, and it will even pose a fatal threat to the ecosystem of this county.

Maybe one of them will be wiped out if you're not careful, but these are especially possible things.

Therefore, Zhao Chen needs to be careful and careful, and do a good job of investigation again and again.

Ask for flowers

If you enter the other side, it will take Zhao Chen several days, so Zhao Chen has already arranged all the relevant work when he came over.

Ying Mengyao is doing things, Zhao Chen is also very relieved, there is Ying Mengyao in the shelter, and there will be no dangerous accidents in the shelter.

Besides, since Ying Mengyao got the three U disks, she has basically been studying the three U every day and spending this period of time.

Although Ying Mengyao spent a long time researching, the amount of knowledge contained in these three U is too much, and this amount of knowledge still needs to be digested slowly by Ying Mengyao.

Ying Mengyao was researching and testing what material was the best choice in different ways, which could avoid the consumption caused by teleportation.

The potential of humanity is endless.

In the face of all kinds of extreme weather and all kinds of disasters, human beings have exerted their incomparably huge potential, and all kinds of high technology have been born in the world under people's painstaking research.

The rapid development of various science and technology not only changes people's lives, but also enables them to better and more calmly cope with various disasters.

The catastrophe is a particularly serious blow to humanity, but it also brings out the potential of humanity from another perspective.

The progress of science and technology in one year is now equivalent to the sum of the previous 10 years, and sometimes it is far more than that. (If you read a violent novel, go to Feilu Novel Network!)

Science advances rapidly, and its impact on people's daily lives is particularly significant.

At the same time, the other side.

Since the official implementation of Plan 1, a large number of people have migrated to the highland areas.

In the highlands, mountain after mountain has been hollowed out to build bases suitable for human habitation.

The interior of the mountain is constantly radiating downwards and in all aspects, and one new miracle of human architecture is born again.

If it were in peacetime, this would definitely be on the list of various hot searches. It's just that this kind of thing doesn't exist at all now, and now human beings can basically only maintain basic communication up to 2G and 3G.

If a sun erupts and a stream of high-intensity particles, these can be fatal to the human race.
