Doomsday: Unlimited upgrades to the shelter

Chapter 118 Upgrading Technology Defense
"Do you want to tell me about this thing?" Ma Wu came over, took the sugar cube-shaped plasma polymer identifier from Xie Yannan's hand, and weighed it in his hand for a while, "What are you going to do? Do?"

"I think the defense of our shelter is still not enough. I plan to use this to shield all the positions exposed to the space. It looks like a sealed wall to outsiders."

"Even if someone can find something by chance, but because of the codes and rules I set up, they can't break in at all. It's similar to the shelter you designed before, a wall."

Xie Yannan did not shy away from talking about his own thoughts, after all, this is related to the comfort of everyone in Bungu, and the current defense seems to be really weak.

"I designed this thing. It's the only one in the world. You kid is really lucky to get it, but you underestimated its ability. It can do much more than that, just like Xiaoxiao..."

Ma Wu seemed to be putting on a trick on purpose, and gave Xie Yannan a meaningful look.

He raised his head and observed the surrounding environment again, "However, the area you want to make is a bit large, and the effect may not be very good. The idea is good, but don't remove the original laser rays."

"The sugar cube serves as the first defense barrier, and the laser beam serves as the second defense barrier."

Xie Yannan originally planned to do the same, "But I didn't bring the amplifier back. How can I use this large area?"

In his hand, he tightly held the sugar cube, which was only 10 centimeters in length, width and height, and he didn't understand.

"It's simple. It doesn't matter if you want the amplifier or not. Let's use meteorites. Meteorites can provide him with enough energy to fully play its role."

Ma Wu explained to Xie Yannan that it can be placed in the center of the valley according to the previous practice, and a circle of meteorites can be placed around the sugar cube. It is best to find a way for these meteorites to wrap the sugar cube and integrate it .

In this way, the recognition signal released by the sugar cube itself is amplified by the meteorite package, making the recognition range wider.

Hearing what Ma Wu said, Xie Yannan immediately understood, "Then the size of the area will be planned according to myself?"

Xie Yannan already had a preliminary plan in his mind, just like standing outside the basin valley and looking at it, it is a bit like a solid castle, but in fact it is not, and it will not affect the sunlight below.

But outsiders can't get in, because it has an identification code, and only human beings who can be successfully identified can come in if they meet the requirements. There is no way to force it.

Just like he went to the third-level shelter before.

Even if it escapes the first layer of design, there is still a laser line of defense behind it, which will directly burn the intruder.

Xie Yannan nodded to Ma Wu to apologize.But I am still a little scared, now all the energy of Bungu has been replaced by the meteorite that Ma Wu said, and he has verified the secret of this meteorite with Uncle Wei before, and Uncle Wei said that he is low-level and has no access to these things. .

Everything seems to be Ma Wu's one-sided opinion, and he seems to be led by the nose by this sophisticated man.

He couldn't help sighing in his heart, and then began to make the kind of thing Ma Wu said.

After a while, a white sugar cube turned into a black sugar cube one size bigger. It seemed to be only twice the size, but it was heavy in the hand, as if it was five or six times heavier. Stones are different.

Xie Yannan didn't have time to think too much. After measuring the center of the basin valley, he buried the sugar cube on the ground and began to use the system to plan the scope and intrusion rules.

【…】

Xie Yannan was stuck here for a while, not knowing how to design this rule.Although this thing only covers the extended and closed position of the top of the basin valley, basically only flying animals have the possibility of intruding...

[Intrusion rules: the host, Wei Xiaofei can enter and exit freely, and all other creatures are forbidden to enter]

He planned not to use the identification rules for the time being. After all, humans in Pengu now relied on gates to enter and exit, so there was no need to design any other rules.

As for Wei Xiaofei... it can only be said that he prefers to be fearless.

[System upgrade...]

After a while, Xie Yannan felt that the originally somewhat hazy sky was a bit darker, but fortunately it didn't affect his sight, and he could still see the sky outside completely.

He was wondering whether the creatures outside saw the same effect as him. He ran outside the basin valley and looked up. With his naked eyes, it sure looked like many curved walls surrounding the basin valley. Come on, it’s not.

Xie Yannan was very satisfied with the effect, and wanted to test how amazing this thing was, so he picked up a small stone and threw it towards the so-called wall.

Nourishing~
The stone bounced back and fell straight to the ground.

Fuck!This machine is really awesome.

【Complete the upgrade】

[Basin valley defense index increased to 85%]

Xie Yannan still doesn't quite understand the concept of 85%, but he thinks that the full level is only 100%, and now he is only 15% short, and suddenly feels that he has reached the pinnacle of his life.

[Scan and upgrade the shelter]

[Does not meet the requirements of the first-level shelter]

Now that the food is self-sufficient in everything, the system actually judges that it is not qualified to be upgraded to a first-level shelter, which makes Xie Yannan very puzzled.

【Reason for inquiry】

【Cannot supply water by itself】

Oh I got it!

Xie Yannan had thought of this a long time ago. It seems that as long as the problem of self-sufficient water source in the valley is solved, the victory of upgrading the shelter is already in sight.

As night fell, the sky completely darkened.

Xie Yannan shared his idea with Ma Wu and Qin Xiaocheng. It was indeed a big project to convert the energy of the meteorite into heat energy and use the basin valley as a completely sealed space to circulate water.

In itself, water is also the key to human survival.

"This method is feasible, but it means that we have to collect all the wastewater generated in our life for secondary distillation, and we also need a wastewater storage tank."
