Global Cataclysm: Infinitely Upgrade Shelter

Zhao Chen had been thinking about upgrading his shelter from the Steel Shelter to the Steel-Tungsten Shelter.

The shelter is Zhao Chen's biggest guarantee, and only when the shelter is raised to a high enough level can Zhao Chen have enough defense capabilities to calmly deal with various disasters.

According to Zhao Chen's memory, the various catastrophes in the future will only get more and more serious, not lighter.

If Zhao Chen hadn't raised the shelter to a level of sufficient security, he would definitely not be able to resist the subsequent disaster.

In this way, the best way to do this is to constantly increase the level of your shelter.

Zhao Chen's previous survival point was completely insufficient, and the infrastructure used to develop some just-needed infrastructure was already dwarfed. Now that he has finally accumulated some survival points, Zhao Chen is naturally a good steel to use on the blade.

Increasing the level of the Vault also has the benefit of increasing the Vault's overall defense and security. At the same time, you can also complete the main quest and get the corresponding rewards of the main quest.

Zhao Chen's previous raw materials needed to upgrade and evacuate had basically been prepared, and now everything is ready, only the east wind is owed.

So, Zhao Chen didn't say a word, and directly upgraded the shelter.

"The system that detects the conditions for the shelter upgrade. "

[Upgrading the shelter, from the steel shelter to the steel tungsten shelter, requires a total of 20,000 survival points, and requires raw materials: tungsten steel...]

[Do you want to upgrade the shelter?]

[Upgrade.] 】

As soon as Zhao Chen's words fell, a rumbling sound sounded in the entire shelter.

Then, the shelter shook violently, frightening the animals in the shelter.

Rhubarb: I'm a real dog, but you're not human either.

Feeling the very serious shaking of the shelter, Ying Mengyao hurriedly rushed out and asked:

"Brother Chen, what the hell is going on? Is there a big earthquake?"

Although every upgrade or new feature added to the Vault in the past will bring a certain amount of jitter, the degree of jitter is definitely not as great as this time.

This time the shelter shook so badly that Ying Mengyao mistakenly thought that a very strong earthquake had occurred.

"There was no major earthquake, it's okay, you just sit in peace."

"Okay, then I'll go and see if the flowers I handed in in the morning are damaged. "

"Let's go. "

It took about 10 minutes of intense shaking before the entire shelter stopped shaking.

After this upgrade, the entire shelter has been completely qualitatively changed, not only the walls have become new, but also some strange textures.

These lines are somewhat similar to the lines of circuit boards, but they are a little different, as for what kind of lines, Zhao Chen himself can't say clearly.

The inside of the vault has changed, and so has the outside.

With the upgrade of the Vault, not only has the defense been greatly strengthened, but the overall security has improved considerably.

Based on the current strength of the Vault and the level of defense of the Vault, even if some tanks hit the perimeter of the Vault, it will not have much impact on the Vault.

If the Vault's defense was 5 before, now the overall defense has been increased to 13.

At this time, Zhao Chen's mind remembered the sound of the system prompt again.

[Congratulations on upgrading your Vault from Steel Vault to Steel-Tungsten Vault, and congratulations on increasing your Vault's defense by 600.] Congratulations on the increased security of your shelter by 580. 】

After Zhao Chen's upgrade, the defense ability and security of the shelter have been greatly improved.

At the same time, the value of these two is also more than 1000.

Zhao Chen originally thought that by upgrading the shelter from a steel shelter to a steel-tungsten shelter, he would be able to complete the main quest. It's just that Zhao Chen is a little regretful, although the defense ability and security have exceeded 1000, but because the comfort level has not reached 1000. As a result, the main quest is not completed immediately.

It's just that the defense ability and security have already exceeded 1000, as long as Zhao Chen improves his comfort level to 1000, then he will be able to complete the main quest and get the corresponding rewards. (If you read a violent novel, go to Feilu Novel Network!)

Compared with Ying Mengyao, Qiao Qian's psychological quality is much better.

Qiao Qian was taking a bath when the shelter was being upgraded just now, but even with such a strong vibration, Qiao Qian still didn't have any effect, and she was taking a bath as she should.

Thinking about Qiao Qian with his toes, he knew that this must have been made up by Zhao Chen.

Ying Mengyao didn't notice the change in the details on the wall, but Qiao Qian noticed the change in the details on the wall.

"Sir, what's going on with these mysterious lines on the wall?"

Zhao Chen passed Ying Mengyao's reminder and also noticed these lines on the wall.

Zhao Chen couldn't figure out what the lines on the wall were, presumably it should be something that strengthened the overall properties of the shelter.

Since it is not clear, then Zhao Chen can continue to study in the future.

These patterns can strengthen the defenses of our shelters. "

When Qiao Qian heard Zhao Chen say this, the whole person came instantly, and began to study these lines on the wall with great interest.

As the king of soldiers, Qiao Qian is all-encompassing in combat and military affairs, and those are also areas that she is very good at. However, these things on the wall are definitely not what Qiao Qian is good at, and even if Qiao Qian spends more time researching, she may not be able to study good results.

At the same time, the other side.

Because Zhao Chen basically comes to the steel factory every day, Yang Mengmeng's status has been greatly improved, and the position she inherited has also stabilized.

Although some people are still not convinced by Yang Mengmeng in their hearts, they dare not show it.

It's one thing to think, it's another thing to practice, Zhao Chen's bullet is not so simple, if they dare to do something out of the ordinary, Zhao Chen will definitely not let them go.

As the number of Zhao Chen's arrivals increased, Zhao Chen gradually understood what kind of person Yang Mengmeng was dragging him.

Yang Mengmeng is very good-looking, although Zhao Chen's base is not much, but from her personality, you can understand that Yang Mengmeng is a royal sister type of girl. Compared with Yang Mengmeng, another girl named Luo Li is a girl who is more dependent on others.

Yang Mengmeng and Luo Li are very good-looking, and both of them are very kind-hearted, after such a long period of contact, Zhao Chen also learned that the two of them definitely have no bad intentions.

Since this is the case, then Zhao Chen can help a little more under the condition of not violating his interests and bottom line.

Of course, no matter how he helped Yang Mengmeng and Luo Li, Zhao Chen's most fundamental purpose was to better exchange resources in the future.

At this time, inside the steel plant, Luo Li quietly asked:

"Mengmeng, do you think Brother Zhao likes you? Otherwise, why would she run into the steel factory all day long?"
