Chapter 85

Since the fuel is related to the follow-up weapons, Shen Cheng turned over the buildings. One of the fuel-based buildings is a fuel-charged building that must be obtained after completing the prerequisite tasks. Buy a water electrolysis machine to make hydrogen and oxygen. Do not let children approach this building, otherwise you may find, boom! 】

The use of electrolyzed water to prepare hydrogen and oxygen is still a problem that has not been completely solved in the world of Shencheng. The main reason is that the initial 'electricity' cannot be completely converted into kinetic energy after hydrogen combustion, which is wasted in electrolyzed water. The large amount of energy lost is not even a good deal compared to the relatively low energy utilization.

Now this technology has reached the end of the world when there are a large number of power users, but it has become a good business - a lightning power user like Chen Feng can complete the decomposition of a large amount of water in one day, but if there is no If the system provides 100% safe black technology, they may also worry about the stability of the power input of the power and whether the hydrogen explosion will blow up the entire research room. But with the support of the system architecture, all these problems no longer exist.

The only problem remains: the purchase of this building must complete a prerequisite task, which is to purchase a sufficient amount of 'Platinum'.

[Preliminary task of the electrolyzed water room: provide platinum and platinum products with a mass of 20kg. 】

"???" I read that right, 20kg?

You must know that platinum is much rarer than gold. Usually, like going to a gold store to buy a platinum ring, the weight is calculated in grams. A ring and a necklace don't even use how many grams of platinum. The system is good, and the opening is 20kg?

This...even if there is a platinum mine, it is too late to extract it!

Shen Cheng was stunned when she looked at the 20kg weight. She suspected that it would be too late to complete the prerequisite tasks within two days. She looked at other fuel-based buildings and found that they were basically 'the prerequisites were not met'.

The oil storage field is more than two days away from them, and there is no natural gas supply nearby. It seems that hydrolysis has become the only stable fuel solution.

Shen Cheng had no choice, so he had to tell Li Weilan about the prerequisite tasks. Li Weilan nodded after listening, and didn't say a word: "There is a way."

She chose 'electrolyzed water'. According to Li Weilan's scientific knowledge not as good as Fu Yanzhou's, he remembered that one of the requirements for electrolyzed water is to use platinum alloy catalyst as the base. In this way, although the amount required by the game system sounds huge, it is also Not crazy.

If you have difficulties, find a way. She has already made a choice. What he does is to help her complete the prerequisite tasks, and he can't just rely on her for everything.

Li Weilan gathered everyone in the base and talked about the difficulties the base currently needs. Immediately, people in the base brought platinum jewelry and rings from their pockets and put them directly into the box in the hall. Just go away.

People who have management stop them, and people get angry instead. There is still a certain market for precious jewelry before the end of the world, but no matter what, there is no such thing as the safety and stability that the base provides now. .

Everyone knows that the 'contribution' they usually make to the base, and the equipment such as mechas that can be exchanged for exchange points, is not an equal transaction at all.

Some people originally felt that they had made less contribution to the base. At this moment, at most, they said to the little girl who counted, "If we contribute to the base, can we accept it as a contribution?" But more silently Jewelry was thrown into the box, and many people would take their wedding and engagement rings and carry them in the mezzanine of their bodies, no matter what.

These things are the last things in emergency life. If they didn't feel that life at the base was really busy, many people would not have planned to take them out.

Shen Cheng looked at the full boxes in the hall of the base a little bit. Although her task was only rising at a rate of four to five grams, seven or eight grams, when she finally scraped together in the base, she also collected 2kg of platinum products. , Compared with the total amount of 20kg, it is indeed not much, but watching this scene, my heart is warm.

They finished collecting the accessories here, Li Weilan packed all the fruits, meat and medicines that had been saved in his space during this time, and went straight out of the base to the tent area.

In fact, the people in the tent area are basically ready to leave.

The Noah base had already sent someone to inform them that there was a tendency for zombies to gather in the direction of the base, and those who still wanted to stay and advance and retreat with the base could all enter the base.

Faced with the pressure of the zombie siege, those who are still willing to fight bloody battles with the base don't have to wait outside. Noah's base is filled with empty beds quickly, and most of them just want to enter the base and wait and see. After discovering that the situation was indeed wrong, they left early, and now the few remaining are businessmen who hope to make a fortune in the war-some of them carry a large amount of war materials, hoping to make the last one before leaving.

But often, those who have the confidence to stay and prepare to leave at this time are all businessmen with certain strength.

After Li Weilan arrived in the middle of them, it was straightforward. He spread the goods with him on the ground, looked at the few merchants who were all around him, and said loudly, "Exchange all of them, only platinum products."

"Platinum?" The rest of the dozen or so groups were stunned.

No one would have thought that at this time, Noah would not accept food or weapons, but would come to collect precious jewelry that could not be used?

crazy?

But the one who took it out for exchange was said to be worth a thousand dollars in Noah's base, and was in short supply. This medicine is said to be a life-saving medicine in the black market. In the end times, there is nothing better than this. Hard hard currency.

Did he trade it for platinum?

The suspicious gazes of several people were only exchanged for a slight smile from Li Weilan: "I'm Li Weilan, you should have heard my name."

"!!!" Come to Noah to do business, how could he not know who he is?

Li Weilan smiled: "The zombie tide doesn't pose too much threat to us. I want to make a piece of jewelry myself to celebrate my hostess. These are my private shares. If you change 20kg, you will change the day, and it will end when the exchange is over."

To please the mistress?

Are there so many trump cards in Noah's base? Ready to celebrate now? Don't worry at all, will there be any problems?

But no matter what, the amount of 20kg... who is not afraid of breaking his neck?

The slander returns to the slander, even if he talks nonsense again, it is still a matter within the Noah base. There are people who foolishly exchange war preparation materials for 'precious metals', and they can't stop them, right?

"..." Several people looked at each other, looked at each other and swarmed up, each began to ask the people around him to take out valuable jewelry, and some of them didn't bring these things, they hurriedly ordered their men to go Small gatherings around to buy and exchange, with a day trip as the boundary.

Shen Cheng watched the completion of the task rise little by little in the next 24 hours, and reached a peak after 12 hours. It seems that all the platinum products from the nearby gathering place were bought.

In the middle of the mission, Fu Yanzhou, who was already shaking and dizzy, finished studying the fur of the three mutant animals that Li Weilan brought back to the base, and determined the methods of cutting, tanning, and sewing them. How much defense can be added to the leather armor made with them, and how much protection can be provided.

When he came out of the laboratory, his face was already very pale, and he felt that he had not eaten, drank or slept for more than a day. Even a research madman could not bear it. Fu Yanzhou had dark circles under his eyes, and he probably could go out and act without makeup. Panda too.

Fu Yanzhou didn't cry even though he was bitter.

But when he walked out of the research room, his head was dizzy and his eyes were black, until Xi Bei happened to see it when he passed by next door.

Xi Bei saw that he was swaying and almost fell. He never expected that a spiritual power user would be able to ruin himself into a younger sister Lin. He held him up, but there was a bit of dissatisfaction in his tone: "Fu Yanzhou, what did you do?"

Fu Yanzhou only felt a buzzing sound in his ears. He supported the wall and then came back to his senses. When he saw Xi Bei's face clearly, he said slowly, "I'm done with my work, it's time to go back to rest. ."

He slept in a single suite, Xi Bei was a little worried, and helped him to lie down on the bed in the room, looking at his tired appearance, he sighed secretly, and couldn't help but persuade: "You don't have to do this... it seems It's like dying in a minute. If you die, it's also a big loss to the base."

Fu Yanzhou opened his eyes on the bed.

The ceiling is icy blue-grey.

It's not his favorite Bai, but after all, it can be regarded as simple and clean, which is already very good: "You don't understand, I'm... atonement."

"Atonement?" Xi Bei really didn't quite understand what he was talking about.

"Yeah, atonement." Fu Yanzhou opened his eyes, "Maybe others can ignore it, but for myself, my heart can never be at peace. It can't be at peace."

Xi Bei didn't know what he was talking about, she frowned vaguely, trying to persuade but didn't know where to start.

Asking her to speak for herself, her opinion of Fu Yanzhou was just licking his face at first, but now, it can only be said that it is more distressed than admiration.

She doesn't know why Fu Yanzhou is crazy about the so-called "redemption" now, but in her opinion, this kind of redemption that is almost self-tortured can be called a mental illness.

This is not healthy.

Xi Bei was hesitant to speak, because she could see that Fu Yanzhou's eyes were full of firmness, which was a kind of persistence that she couldn't persuade.

Such a person... Xi Bei sighed and closed Fu Yanzhou's door.

**

After Fu Yanzhou's research is completed, the [Equipment Building Room] on Shen Cheng's mobile phone can be built.

The construction price is 100G, or 100kg of refined metal and 100Kg of wood. If it is not facing the urgent situation of zombie siege, Shen Cheng should choose to let the villains in the base slowly collect materials. Metal can be refined, but now that time is running out, she chose krypton gold.

Soon, everyone in the base heard the announcement of the system machinery: "The base is open: equipment building room. Please bring your raw materials and contribution points to residents in need, and go to the building room to complete the cutting."

"!!" raw materials? Contribute points?

The latter is what almost all welfare buildings in the base need, but raw materials?

Some people thought about the materials on the mutant beasts that had just been put into storage in the base warehouse. Some people contributed more points, so they exchanged some mouse skins and teeth first. They were still thinking about the base before. Why did such a batch of products suddenly appear on the shelves, it turned out to be used here!
