Global Cataclysm: Infinitely Upgrade Shelter

Two rounds of the sun appeared in the sky.

These two rounds of the sun are two colors of the sun, one is red and the other is blood red.

The two suns appear to be about the same size, appearing in the sky as if they were twins.

But in fact, after satellite measurements, the size of the two suns is hundreds of thousands of times different. The reason why it looks almost the same is because of the distance.

The small sun is closer to the Earth, and the real Sun is much farther away from the Earth.

The two suns hung above the sky at the same time, and they looked extremely dazzling.

This is a beautiful double sun moon, but the people of the earth do not have the heart to appreciate these two rounds of the sun.

For human beings, this scene in front of them is not only not beautiful at all, but it seems particularly cruel, as if it is a scene of the end of the world.

Zhao Chen came to the surface of the glacier and felt the scorching breath in the air.

As soon as the double sun appeared, the dazzling light landed directly on the earth.

Glaciers that used to take a long time to melt are now melting very quickly because there are two suns in the sky.

Fortunately, the two suns did not bring the particularly extreme temperatures of 053 and would not have a particularly large impact on human actions.

Unfortunately, for a long time to come, humans will survive in the hotter seasons.

The hot weather will last for a long time.

Originally, there were many springs, summers, autumns and winters, and the only places with distinct seasons were spring, summer, and autumn.

The four seasons seem to have no winter.

Glaciers in the Antarctic and Arctic will melt gradually, eventually leading to a sustained rise in sea levels.

The impact of the two suns on humanity goes far beyond that.

When Zhao Chen saw two suns appear in the sky, he didn't feel particularly much. He had already experienced all kinds of disasters in his previous life, and now seeing this familiar look in front of him seemed to make him feel like he was back before.

The era is still that era, but the current Zhao Chen is not the previous Zhao Chen.

In the past, Zhao Chen could only become an ordinary ordinary person in the official shelter, but now Zhao Chen built a shelter by himself, and he is the only master in his own shelter.

From the moment he decided to start building the shelter (BCCE) on his own, Zhao Chen's fate was in his own hands.

Your own destiny is in your own hands, and this is the eternal king.

A few days passed in a flash, and the biogas digester next to Zhao Chen's shelter had been built. Not only that, Zhao Chen also installed the relevant pipes in the biogas digester next door to the shelter.

Zhao Chen saw that the biogas digester had almost been built, and the places that should have been perfected were almost perfected, and he was not ready to continue to spend extra time on the biogas digester, because it was completely unnecessary.

"system, check the conditions for the upgrade of the digester. "

[It has been found that the host has built a primary biogas digester and has the relevant raw materials for the digester upgrade.] Upgrade direction: boutique biogas digester. 】

【Boutique biogas digester: The boutique biogas digester is upgraded on the basis of the primary biogas digester, and the safety of the boutique biogas digester has been greatly improved compared with the primary biogas digester. The boutique biogas digester can prevent the accumulation of air pressure, and the boutique biogas digester is specially added with a series of air treatment equipment to isolate the air flow exchange from the outside world. At the same time, it has a natural sterilization effect. 】

[Consume 1000 survival points to upgrade to a boutique biogas digester, is it upgraded?]

[Yes.] 】

When Zhao Chen saw that the biogas digester could be naturally sterilized, he immediately chose to upgrade the biogas digester. (If you read a violent novel, go to Feilu Novel Network!)

Ordinary biogas digesters do not have any sterilization effect, and animal feces are excreted directly into the digester. If the high temperature does not kill the bacteria in question, the bacteria will flow out of the ground through the air current, posing a threat to human life.

Zhao Chen's biggest concern before was not the explosion of the biogas digester, but the problems related to bacteria.

Biogas digester explosion, it can be prevented by some physical means. But if you don't pay more attention to bacteria, this virus is simply impossible to prevent. Now that the system has been upgraded, the digester itself has a natural sterilization effect, and Zhao Chen no longer has to worry about bacteria harming them.

I have to say that the system is produced, and it is really all high-quality products.

After the biogas digester was built, Zhao Chen directly moved the animal farm to the biogas digester. From then on, the animal's manure will fall directly into the digester, and they don't have to waste any energy to dispose of it.

Rabbit and chicken smell good, but their droppings stink too much. Fortunately, there were robots to deal with before, and if Zhao Chen was allowed to go into battle in person, he would definitely not be able to stand it.

Now that the digester handles the manure itself, the associated problems are gone.

[Congratulations on building a biogas digester, congratulations on increasing your comfort level by 50.] 】

[The main quest has been released, please improve the comfort, safety, and defense attributes of the shelter.] Completing the mission will give you the corresponding rewards, which are as follows: Completing the mission will give the large motorhome a diving function, which can dive 500 meters into the sea and have a battery life of more than two months. Large RVs have the function of dual drive on land and sea. 】

[The comfort, security, and defense attributes required to complete the mission are as follows: 50/3000.] 150/3000。 200/3000。 】

Zhao Chen found that with the continuous enrichment of his shelter, the attribute points required for the main quest released by the system have also increased from the previous 1000 to 3000.

The difficulty of completing the task has been greatly improved compared to before, but seeing the system rewards of the main quest, this makes Zhao Chen particularly greedy.

Now Zhao Chen's large RV can only run on land or desert, in other words, it can only run in places where there is no water. Zhao Chen's large RV wants to dive, which is completely impossible. If you fall into the water, it will quickly turn off in a few seconds.

Zhao Chen has always wanted to build his large RV into a super all-round RV that can be driven in three places: land, sea and air.

For Zhao Chen, this is just an idea, and now that there is an opportunity to realize this dream, he will naturally not let it go.

The properties of the Vault must be continuously improved, so that it can withstand all kinds of disasters. However, the attributes of large motorhomes must also be continuously improved, because it involves the abundance and convenience of obtaining their own resources.

The construction of the shelter continues, and Zhao Chen plans to tell other manufacturers about his construction of an underground market. Synchronize this with this.
