The accident in the Guangdong water settlement seems to be a sign of disaster. There are many refugees heading north in the south. These escapers have brought about the loss of one small and medium-sized settlements. When the survivors passed through the city, a small part chose to stay, and most people still chose to continue north.

In fact, the situation in the North is not as good as they expected. Zombie fish and mutant worms not only appear in the south, but also in the north, and some small and medium-sized settlements near the coast are also being destroyed. Compared with the south, the weather in the north is more arid. After entering the end of April, the temperature has risen sharply. Until the end of July, there have been only a few small rains. Many places can see the land cracking. The long mouth is like the desperate pain of the earth.

The drought in the northwest region is more serious. The largest returning land in the northwest has been drought-ridden to the point where daily drinking water is not available. The ground is full of adult-sized cracks, except that the mutant plants can survive strongly, and the ordinary food crops are almost All were sunburned and killed. However, the living environment of Huilan is bad, but the soil is sparsely populated, the weather is hot and dry, zombies and bugs don't love to visit there. In a sense, the survival pressure is smaller than other places.

With the landing of zombie fish, many survivors felt that they were not as safe as inland. Many survivors knew that the living conditions in the northwest were bad, and they still migrated there.

Because Wu Ye and Qin Wuhua are the same as the five-level abilities, Yucheng is a living signboard. In addition, the internal management of Yucheng is relatively democratic and orderly. At the same time, there are also many practical guarantees. Even if you can’t kill zombies, you can Live down. Based on these two points, it is still very attractive to survivors.

Therefore, as of the end of July, the survivors of Yucheng have been reduced from the beginning of the year, and today, Yucheng is a rare odd.

"Success, success, and finally succeeded!" Professor Li stared at the crystal nucleus of the instrument center on the experimental table, ecstatic.

Professor Gu was also excited to turn around the instrument. He came to Yucheng, but in just two months, the original white hair had been completely white, but his eyes were bright and stunned.

Ji Yun said with excitement: "I am going to find the boss, I am going to report to the boss."

In order to prevent the research data from leaking, the research institute's telephone can only dial other extensions within the station, and can't get outside. There is a special signal interference within 100 meters of the research institute, and even the mobile phone can't get through.

This is still the morning, Wu Ye has already accompanied Qin Wuhua to kill the zombies with him, and when they come back at night, he not only received the news of the successful production of the nucleus energy converter, but also learned that Professor Gu And his students have built a data model of the nucleus energy hood.

Wu Ye and Qin Wuhua exhaled at the same time, and they felt that the pressure on their shoulders was much lighter.

While browsing the model data, Qin Wuhua asked: "How long does it take to get the energy cover?"

Professor Gu sighed and smiled. "This is just our theoretical model. To make this kind of energy cover, we need this theoretically super-metal. As far as I know, this metal has always existed. In our theoretical data, it is impossible for the environment on Earth to produce this metal."

Wu Ye slightly hesitated and asked the system: [Is this theoretical data model feasible? 】

Wu Ye will pay Fu Shuai as a comrade-in-arms some time ago, and exchange him with the "Basic Breathing Method" and "Introduction to Spiritual Training", and give each of the guards a redeemed low-grade protective suit, modified low-level Protective clothing can completely protect the palms and soles of the feet, maximally avoiding parasitic worms in combat. In addition, he also needs to open monitoring from time to time to monitor the situation around the city, to eliminate the zombies with a closer distance and higher level, and spend a lot of his points and crystal nucleus.

Through constant trading, the system has stored a lot of energy in the dark, and the level has also been upgraded. In the past, it only covered the residential area of ​​the surveillance city. Now the monitoring scope can cover not only the entire city, but also the monitoring of the city. The situation of one hundred kilometers outside.

In view of the improvement of this time, the system is very rare to tell the stupid host directly: [The theory is too rough and primitive, can only play a certain barrier role, without the isolation function and invisible function of the energy cover provided by the system, according to their theory, The energy hood can only withstand up to seven million cadres and mutated worms. 】

The energy cover is different from the wall and can only surround that circle. According to Professor Gu's theory, the energy cover they made can cover the entire city in an elliptical shape, centering on the energy mask instrument, in the air and underground. Each extension is 50 meters, and the city is completely wrapped up. Even if human and energy fluctuations cannot be isolated, the level of security is absolutely on the wall of the worm.

Two less busy asking the system: [Can I redeem that super metal? 】

auzw.com After the system’s deduction of stupid host retrieval points, the control interface popped two or three pages of various ore names, and the first five were not considered by Wu Ye. Even if it is the most expensive and the cheapest, 1 kilogram will be a full 5000 points, 10 orange crystals, and several later, the price per kilogram is more than a million points.

Two little hearts raised a bad premonition. [If you want to build an energy cover that can cover the entire city, how many of the cheapest ore is needed? 】

In the mechanical sound of the system, there is a plagiarism in the city of 'business is coming.' [Not much, if the casting is successful, 200 kilograms of ore will suffice. 】

200 kilograms, 200 kilograms is less than 10 seconds to look at the control panel, he worked so hard for so long, the account on the account barely maintained in the 12> two little heart q version of the villain tears watching the points will soon disappear, very Meat pains: [first two kilograms. 】 哎, high investment and high return, will be transferred back from others in the morning and evening! At least it is much cheaper than buying an energy cover directly with the system? From another point of view, he still earned, and two were silent.

The system speed deducted the points on the stupid host's book, and the orange crystal in the space ring. Wu leaves trousers pocket sinking, the pants are not safe. He was busy reaching into his trouser pocket to grab the ore. The 4 kg ore was only the size of an egg. He was very skeptical that this was enough for Professor Gu to do the preliminary test.

He first put the ore into the ring, and then he was quite confident: "Everything is in case, you write down the characteristics of this metal, I will arrange for someone to look for it, maybe I can find it."

Professor Gu is obviously not very optimistic about Wu Ye's proposal, but he still told Ji Yun to write down the metal characteristics and hand it to Wu Ye.

I talked about the nucleus energy for a while. Before leaving, Wu Ye asked the system to redeem three physical fitness pills, and the blackmail system sent him a bottle. He put the bottle with the pills on the experimental table. You have worked hard for a while, and the things in it are rewards for the three of you. Go back and eat it and take a rest, then continue to study. When you make all the things I want, I will give them again. Your other rewards."

The working environment of the laboratory is always damaging to the body. Now is the key period for people to use. Wu Ye does not want to kill chickens and take eggs to plague several major research leaders.

With Qin Wuhua leaving the institute, Wu Ye long sighed with a sigh of relief: "There is progress, and finally I can put a little snack."

Qin Wuhua asked while driving: "Super metal..."

Wu Ye took out an irregular green ore from the space ring. "Take it to Professor Gu in two days. This thing is very expensive. I hope they can make the energy cover as soon as possible."

After a moment of silence, Qin Wuhua said: "Aye, thank you."

The second one will climb up the line: "Let me be above, I believe that you are sincere."

Qin Wuhua showed a hint of helplessness and a smile: "In addition to this request. Of course, if you want to take the initiative, I will not mind, just like my last birthday..."

The second time suddenly rose a red face, "I am, you want to be beautiful! Bastard, that day is the old man has not found you to settle accounts..."

The two talked and laughed, and soon returned home, washed some, simply ate dinner, two less thunder can not play the **** game, Qin Wuhua gave a fire to the maintenance, and then called the big gray, and practice together. Like the owner, the rabbit boss who did not have a good interest, did not know how to read the game on the owner's lap, and did not know how to understand it. The small appearance looked very exciting. Unfortunately, not long after the excitement, I fell asleep on the owner's lap.

The day full of killings and busy days finally passed. When Qin Wuhua hugged the people in his arms, he felt that even if he was in the last days, it would not be too difficult.

After two days, Wu Ye handed over the ore that was unintentionally picked up to Ji Yun and asked him to take the experiment. Ji Yun has seen all kinds of magical means of Wu Ye. He intuitively thinks that the ore that he has never seen before may be what they need. If they say nothing, they will take it back and test it. After a rigorous inspection, the ore is completely in line with the 'super metal' that exists only in the theoretical data. The metal content is over 80%. The ordinary tools can't refine the metal at all. Finally, it is still looking for Yang Lina to help, and it took a little half a day. In the end, the 'super metal' was thoroughly purified. The purified metal is very flexible and emits a touch of green light from the inside out, which is very beautiful.

With the experimental materials, Professor Gu and Professor Li, who have taken the physical fitness pills and become better, led their researchers, and continued to study day and night, and finally succeeded in creating a study that could cover the entire institute after half a month. The range of energy hoods, the experiment finally succeeded.

At this time, news came from the north, and the d-virus vaccine was developed in the settlement of the capital.
