Doomsday: Unlimited upgrades to the shelter

Chapter 245 Upgrading the Shelter
Sixteen continued to pause for a moment, as if he was perceiving the specific direction.

Then he raised his hand and pointed to a dark forest not far away, "It's in that forest. Let's go get the meteorite and leave. The longer we delay, the more dangerous we will be." "

Shiliu walked in front to lead the way, Xie Yannan and Xiaoxiao followed behind, the three of them moved carefully and looked around again.

Fortunately, since I came out of the cabin, I haven't encountered any abnormalities.

"These dark things are really meteorites."

As the grove got closer and closer, Shiliu's perception became stronger and stronger, and he was naturally agitated a lot.

Xiaoxiao turned on the light in the dark place of the grove as usual.

Sure enough, there are meteorites with blue light hidden in this grove, which is the same as the one that Ma Wu gave to Xie Yannan before.

"Just take some of it away, not all of it."

Sixteen frowned, and said something lightly.

"Why, is this stone important to you?"

Just now Shiliu and Xie Yannan have reached an agreement, and this thing is obviously as common as the soil on the earth.

"Leave a little. In fact, our bodies are not cast with steel, but with this kind of meteorite. Our tribe does not have children, but casts offspring. Every couple has the ability to cast two children. If you take the meteorite Taking them all away means that my people will no longer be able to forge future generations.”

"But you also said that they want to harm us people on Earth, shouldn't you go back to your original planet?"

Xie Yannan didn't feel that Shiliu's words were unreasonable, but that his clan members had hurt him like that, and he was still speaking for them, so he didn't understand.

"Hey...it's up to you."

Shiliu seemed unwilling to say anything more, and sat on the side sullenly.

Xie Yannan lowered his head and pondered for a moment, then decided to take away most of the meteorites. The reason why a small part was kept was entirely because of Shiliu's reason.

"Let's go, let's go back and find your flying motorcycle, and then go back to the shelter."

After storing the meteorite in the system, Xie Yannan waved his hand, staying for a minute longer would be more dangerous.

"The flying motorcycle is on me." Sixteen paused, and took out a keychain-sized object from his jacket pocket.

"The last time I used your energy ring, I reconfigured my motorcycle. Now I can carry it with me and control it with my mind. Once I put it on the ground, it will naturally grow bigger."

Sixteen lightly threw the key chain motorcycle to the ground, and the motorcycle gradually swelled up, and then stopped abruptly after it swelled to the same size as before.

Xie Yannan took Xiaoxiao and Shiliu on the motorcycle together.

Because Shiliu said before that each clan member has his own corresponding vehicle, but he can only operate it by himself. Therefore, even after sitting on it several times, Xie Yannan has not been able to operate the flying motorcycle by himself. Occasionally, it is still a little bit... My heart felt itchy.

The speed of the flying motorcycle is indeed much faster than that of the jumping car. Since the flying motorcycle, the jumping car has been abandoned.

Just after being in the shelter for a short while, an automatic announcement came from the system.

[The host has been detected to complete the task of collecting meteorites]

[System rewards assist in completing a project]

Xie Yannan originally planned to build a capsule tunnel to connect the refuge and the weapon base directly, but now all the weapons have been taken into his bag.And that weapon base is not hidden, so there is no need to waste an opportunity to do useless work.

However, the defense of his own refuge is really weak, Xie Yannan has already removed all the surrounding mountains, and built a real refuge on the ground.

Coincidentally, this time he was given a chance.

He intends to remove all the surrounding mountains and build the surrounding area into fully reinforced concrete buildings.

[The system has automatically turned on the smart mode]

[Re-plan the surrounding buildings according to the idea drawings uploaded by the host]

This time it was a thorough rectification of the refuge. After all the surrounding mountains were removed, a reinforced concrete building was built.

But in order not to be so conspicuous, Xie Yannan still planned to build a layer first.

The thickness of the wall surface of an ordinary building is five centimeters, and the load-bearing wall is ten centimeters.

But the shelter Xie Yannan built was specially designed by him. It mixed glass slag and lead, as well as the strongest alloy, making it nearly one meter thick.

The hard alloy material is used to resist external impact and bombing, and the mixture of glass slag and lead can resist external radiation. In this way, the most basic defense has a qualitative leap from the original few soils.

Xie Yannan also studied architecture. He understood that unless several heavy cannons were aimed at and bombarded with such a structure, its defensive power would be much stronger than imagined.

It's just that the top of the house has always been the weak point.

Because there is still soil and places for planting vegetables on the ground of the shelter, it is restricted that the top of the head must be transparent, otherwise the photosynthesis of indoor vegetables will be affected to a certain extent.

"Xiaocheng, is our current electricity still enough?"

Xie Yannan asked Qin Xiaocheng next to him, if it is enough, it can be turned into artificial lighting to create a simple ecosystem to maintain the photosynthesis of the shelter.

"The power is completely enough, and the batteries made by the shelter have been piled up to almost fill a room."

"Then I plan to use our current power system to support the photosynthesis needed by the entire shelter. I don't know if there is any problem. I will convert all photosynthesis into artificial electricity."

Xie Yannan is definitely not as familiar with Qin Xiaocheng as he specializes in technology, such as electricity.

"There is no problem, but the output is expected to be reduced a bit. After all, artificial photosynthesis does not have ultraviolet light, and ultraviolet light can also play a certain stimulating effect in the growth process of actual organisms."

"Then we will create the same microenvironment so that the vegetable and fish ponds in the greenhouse can survive normally."

Xie Yannan made up his mind to upgrade the protection of the top of the shelter.After all, it is the shortest piece of wood that determines the water capacity of the barrel. No matter how well the rest of the protection is done, if the top is compromised, it will be useless.

He paused, planning to not only spend a lot of money to make the defense above his head the same as the surrounding walls, but also plan to open skylights on it and make some closed windows full of meteorites.

Although the meteorite is not very thick, its actual defense ability will definitely not be weaker than that one-meter wall.

And in this way, more or less some natural light can penetrate.

When it is not daytime, the entire refuge is still in a state of darkness.
