Global Cataclysm: Infinitely Upgrade Shelter
Chapter 60
[Ding, has been successfully upgraded to a steel shelter, survival point -2000]
[Remaining Survival Points: 2700]
【.........】
The entire rock shelter suddenly began to tremble.
The outermost rock structure is constantly evolving, transforming into pale silver steel.
"What's wrong?!"
"Did there be an earthquake?!"
"Sir, let's take refuge outside, in case of collapse, we'll all be buried here. "
"Woohoo!"
“........"
Feel the vibrations throughout the rock shelter.
Ying Mengyao and Qiao Qian, who were sitting on the sofa, suddenly stood up nervously, and Rhubarb also began to scream restlessly.
As for the meat rabbits, meat ducks, and white-feathered chickens in the animal breeding room.
Their reaction is even more violent.
I was scared to pee on the spot.
If it weren't for the previous upgrade of the inferior sewage system, which could directly clean up their excrement, it is estimated that dealing with such trivial matters would have made Zhao Chen's brain hurt.
"Don't get excited, it's just routine. "
Zhao Chen waved his hand, signaling everyone not to be nervous.
The complete transformation of the rock structure into a five-meter-thick steel structure naturally produces violent shaking in the process.
Anyway, it doesn't collapse the vault.
After about a minute, the entire rock shelter ......
To be precise, it should be the steel shelter, which has regained the "six, seven, seven" to a calm state, but the current defense capability is far from being comparable to before.
[Mission Progress: Comfort 100/1000, Survivability 300/1000, Defense 150/1000]
【........】
Defense is directly increased by 100 points.
Upgrading the overall structure of the Vault once will allow you to directly complete 10% of the quest's progress.
If you upgrade again.
It is estimated that the growth rate will be even higher.
Zhao Chen glanced at it silently, the next level of the steel shelter-
【Steel Shelter】
[Upgrade direction: Tungsten Steel Shelter (20000)]
[Upgrade Effect: The outer layer of defense will be replaced with 10 meters of tungsten steel, increasing the defense ability of the Vault.] (Defense +500)】
[Upgraded raw material: 1000 tons of tungsten steel]
[Attributes can be attached, and a certain survival point is consumed according to the effect]
【.........】
That's 20,000 survival points.
made Zhao Chen think for a while that he was wrong.
Although the effect is very powerful, and you can directly complete half of the mission progress of the defense ability, but the survival point required is too outrageous, right?!
Complete the third main quest.
I only have 10,000 survival points.
"The thickness doubled again, a full ten meters thick layer of defense. "
"It's about a four-story house, and the height is changed to thickness, and just thinking about it feels flawless. "
"Moreover, the material used is tungsten steel. "
“........."
Tungsten steel is the hardest steel!
It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc.
In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500, and still have a high hardness at 1000.
It is known as the tooth of modern industry.
The use of tungsten steel products is very extensive.
However, looking at the entire Dragon Country, there are only 4 enterprises with an annual output of more than 1,000 tons of tungsten steel.
And all of them are not within the scope of Hangzhou City.
This upgrade condition, the opening is 1000 tons of tungsten steel, which is just like a joke, and it is estimated that it can only be upgraded with survival points.
"Isn't that embarrassing me. "
Zhao Chen thought silently in his heart.
The next stage of the Steel Vault is the Tungsten Steel Vault, which requires 20,000 survival points.
This is already the hardest steel.
So.
In the next stage, what materials will be used to build the shelter?
It is impossible to imagine and cannot imagine a harder material.
"Sir, what's going on?"
"It's nothing, it's just a little bit more about our survival rate, and now the possibility of being able to withstand the shockwave of meteorite falls...... Yes%. "
In Zhao Chen's memory.
The small meteorite that fell in Hangzhou City was a suburb far away from his refuge.
With the defense of the Steel Vault, it was not a problem at all to withstand this wave.
"Huh?"
The existence of the Vault system is unknown.
Qiao Qian and Ying Mengyao couldn't understand the meaning of Zhao Chen's words.
"Okay, let's get to the next question. "
"Yes. Qiao Qian buried her doubts in her heart, and then said, "The second question is about the design of the Steel Gate. "
"Is there anything wrong with the Iron Gate?"
"It's only one meter thick, and even if there are three of them, it feels like it's a weak defense. "
"This is easy to solve. "
"Also, it doesn't have an automatic door opening function. Qiao Qian said.
There is no automatic door opening function, and entry and exit need to be manual, which is really troublesome.
You have to run over and press the button.
The steel door will slowly open, and the efficiency is too low.
"Defense, automation. "
"These two problems are not difficult to solve. "
“........."
In his own hands, there are still 2700 survival points.
Raise the defense of the gate, naturally.
Zhao Chen directly inquired in his heart, the upgrade conditions of the three steel gates-
【Steel Gate (3)】
[Upgrade Direction: Thickened Steel Gate (600)]
[Upgrade Effect: Increases to a thickness of 3 meters (Defense +60)]
[Upgrade raw materials: 30 tons of steel] (read violent novels, just go to Feilu Novel Network!)
[Attributes can be attached, and a certain survival point is consumed according to the effect]
【.........】
The upgrade of the entire shelter structure requires a huge amount of survival points.
However, simply upgrade the three steel gates.
It's going to be a lot cheaper.
"Directly upgrade the three steel doors. "
“........"
[Ding, has been successfully upgraded to a thickened version of the Steel Gate x3, survival point -600]
[Remaining Survival Points: 2100]
【........】
As the gateway of the steel shelter, the thickness of the three steel gates has been directly tripled, and although the materials used have not changed, the defense ability has been truly improved.
For example, the M16 assault rifle can only penetrate 9 mm thick steel plates within 400 meters.
Barrett's heavy sniper rifle can penetrate 16 mm thick steel plates within 200 meters.
Even a tank shell can penetrate a steel plate up to 1 meter thick.
In the face of the three-meter-thick steel gate, it can only mean that there is nothing you can do, unless it is with a special armor-piercing shell!
[Mission Progress: Comfort 100/1000, Survivability 300/1000, Defense 210/1000]
【........】
"Additional property – automatic door opening. "
Just finished upgrading.
Zhao Chen followed Qiao Qian's suggestion and immediately attached new attributes to it.
[Ding, thickened steel door, additional automatic door opening attribute]
[Automatic door opening (elementary): Able to distinguish friend from foe, within a range of 10 meters, to automatically open and close the door (10)]
[Survival Point: 100]
【........】
This price is much more affordable.
A mere 100 survival points, as long as it can improve the defense of the Vault, it is worth the effort.
After all, hoarding survival points all the time is just the most wasteful thing to do.
Only by leaving a small number of survival points, and fully transforming the remaining survival points, can they be used to the greatest extent possible.....
Instead of letting it be a series of useless numbers in the system.
Determine the additional attributes. "
[Ding, thickened version of the steel gate, additional automatic door opening attribute, survival point -100]
[Remaining Survival Points: 2000]
【........】
[Mission Progress: Comfort 100/1000, Survivability 300/1000, Defense 220/1000]
【........】
It cost 700 survival points to directly solve the problem raised by Qiao Qian.
That's where survival points come in!
And the defense rating is also catching up, soaring all the way to 220, which is not much different from the survivability of the highest rating.
"Any other suggestions?"
"In terms of thermal weapons, there is only one submachine gun, and the ammunition reserve is not much, which is actually a bit small. "
"There's nothing I can do about it. "
The buildings of the Steel Shelter can also be solved directly by yourself with survival points.
However, the problem of thermal weapons.
I haven't been able to reach the conditions for a while to be able to complete the production line and supply enough bullets.
Even the Longyan Type 05 submachine gun given to Qiao Qian, as well as 10 magazines, still completed the second main quest, and the system rewarded them with items.
"The gun ban in the Dragon Country is very strict. "
"The industrial-grade 3D printer I bought can use materials to print some daily necessities, or industrial supplies. "
"But if you want to print hot weapons, the current conditions are not enough. "
“.........."
Zhao Chen shook his head and said.
The usefulness of the survival point is indeed great, but it does not mean that it can be created out of nothing.
Even if you upgrade it again to meet the conditions for printing hot weapons, but it lacks the most important gun-crafting blueprints, it is just a decoration, and can only be used to see.
At this stage.
I can only make do with the crossbow with the god arm.
Able to shoot ten times in a row.
The firing range is up to 300 meters.
Coupled with the concealment characteristics of the crossbow, in fact, it is not inferior to the performance of ordinary pistols at all.
"Okay. "
"The defenses inside the vault, if I improve it as I say, are actually almost enough for 0.8. "
"However, although the main enemy we have to fight is natural disasters, the external defense facilities to protect against humanity are actually an essential component. "
“........"
There's no way to get more thermal weapons.
Qiao Qian could only temporarily give up more of her thoughts, and instead changed her target to the external defense facilities of the shelter.
Today's steel refuge.
All that is raised is internal defense.
The external defense, one could almost say that it was undefended.
When someone sneaks to your door, it is estimated that they will not notice anything, which can easily cause the situation of being yin as soon as you go out, so it is necessary to prepare in advance.
"External defenses ........"
