Li Xuanyuan refreshes the data of the environmental detector, and a numerical display on it is still booming all the way.


    He said: "it''s not the time yet. The values of temperature, wind and rainfall have not changed much. Only the pH is increasing. I''ll go out and have a look. You can contact the outside to see if it''s the only change here or the large-scale one. "


    Li Xuanyuan was a little worried about Hou Ying. When he got out of the train, he felt the change of pH value in the environment. He found that the concentrated acid was carried in the rain, which was much more severe than the acid rain before the end of the world. The residual building surface fell off and corroded in less than a minute after the acid rain fell, which showed the strong acidity.


    And there was a faint sour smell in the air. Li Xuanyuan tested it with the leaves of twin banyan trees. He was disappointed and came to the conclusion that it was not the ability that caused the weather change nearby.


    He is about to call Hou Ying back, a man carrying a big net bag broke into his sight, and then stopped in front of him.


    "Why did you come out? Go back. "


    Hou Ying frowned, patted his ass and urged him to return to the car. She told Liu Zhan to open the warehouse door.


    After putting things in place, Hou Ying simply disinfected, washed and changed her clothes before she came out. Liu Zhanzheng talked to Li Xuanyuan, then turned back and said, "brother monkey, I have already asked. Acid rain occurred in the Yellow River base and the Pearl River base at the same time. The buildings in the main city of Zhujiang base have been reinforced with biomaterials and level 4 abilities, and there is no corrosion yet. However, in addition to the new outer city of the Yellow River base, the buildings of loyalty and inner city are damaged to varying degrees. The acid rain came suddenly, and the concentration is still soaring up to now. "


    Hou Ying nodded. Before the acid rain came down, he noticed that the weather would change, so he packed up and came back in time.


    Dongfang Bai said: "will this lead to a wave of zombies? Has the law of celestial change been broken? "


    Hou Ying shook her head, "the concentration of zombie virus has not changed for the time being."


    Ji Yao said: "I hate people who break the rules. God, I don''t want to give people a living! Brother monkey, what shall we do now? "


    "What do parents and sisters say? Can I help you? "


    Liu Zhan gave a negative answer, and Hou Ying said, "let''s go back to the source of the desert. If there is a zombie tide, you can go back to support in time."


    He had planned to stay near the desert source for a while in the next metamorphosis. Ji Yao goes to drive. Liu Zhan tells Hou Ying his inference about the source body of the desert again and shows Hou Ying the comparative data he has done. Then he added: "I suspect that the change of magnetic field over there may also be due to the naked meteorite. Haven''t monkey found any zombies near there? If it''s the meteorite itself, it can also explain why the doomsday has become a blind spot for satellite exploration


    Dongfang Bai also raises Ji Yao''s question about the intelligence zombie.


    If we lose the protection of meteorite lake water and sea water, which makes the energy of the desert source body attract intelligent zombies thousands of miles away, then why are there seven speed intelligent zombies wandering around the desert and creating three zombie empty cities? Besides


    Dongfang Bai also said his question: "according to monkey brother''s experience, the repulsion time is only about three minutes. If this change happened after the zombie tide, it''s easy to say, but what if it happened during the zombie tide? How can they reach the source in such a short period of time, or how can they reach here after the repulsive force reappears and the energy overflow stops? If it happened before the zombie tide, then this issue is even more worthy of discussion. " Hou Ying nodded with a smile, "the consideration of the East is very reasonable."


    Liu Zhandao said: "I have no idea about these problems, but I think the biggest difference of nudity meteorite is still the key to attract intelligent zombies."


    Hou Ying: "when the next zombie tide breaks out, everything will be known."


    Liu Zhan wants to say something else, but on second thought, it''s really meaningless to argue now. Facts are better than eloquence. Instead of spending time guessing, Hou Ying should see it with her own eyes and then reveal the answer.


    At this time, the acidity of the rain finally stopped at a peak.


    Li Xuanyuan said: "the physical property damage caused by this acidity is only a little worse than that caused by concentrated sulfuric acid, and the buildings built by Level 3 powers may not be able to withstand it."


    Dongfang Bai: "what is the cause of the weather change? Is this the earth we live on? Even if the virus carried by the meteorite makes a mess of the internal ecology, the weather will not mutate to this extent, will it? It''s all over the country and all over the world. Can science explain that? "


    He''s going crazy.


    Four seasons, cold and warm, morning and dusk, these things are completely irregular after the end of time. The same is true of wind, frost, rain and snow. Now even concentrated sulfuric acid comes down. Where do these acids come from? Even the most polluted industrial cities have never heard of sulfuric acid splashing in the sky!


    Liu Zhan patted him placidly on the shoulder, "experts have studied for two years, but they don''t have a precise word, so don''t bother to think about it."After they arrived at the edge of the desert and waited for three days, the pH of the rain did not change, and the zombie tide did not return.


    At this time, the Pearl River base sent communications.


    Duan Yin talked about two things.


    First, the construction of Chuanyuan base was seriously damaged. He asked Zhujiang base for help. He assigned five elements powers to reinforce the construction and asked them to buy biomaterials at a high price. The cost of the former is the method of the five elements power conversion and proliferation.


    Second, the Pearl River base received a visit from overseas visitors, who brought a good technology.


    The first item he said surprised Hou Ying and them.


    At the beginning, the fusion five elements ability creature was bred. In the same crystal nucleus, the fusion creature can play the five elements ability of different attributes. Since then, Hou Ying has never given up the research on the integration of the five elements, but so far it has not achieved much.


    Duan Yin said: "my people have verified that they can really merge and multiply the five elements with their methods."


    He simply put forward the method of tichuan original base, using the principle of five elements, namely: water generates wood, wood generates fire, fire generates earth, earth generates gold, and gold generates water. The water system power can stimulate the wood system power by absorbing the five elements crystal of the wood system power attribute, and through the conversion and fusion of glands, after the reserve reaches the water system attribute crystal nucleus beyond the body .


    This method seems simple, but it''s not easy to sit up, and most people don''t have such bold ideas and creativity, so it''s also a top secret of Chuanyuan base.


    Hou Ying was very sorry to hear that. He had thought of this method at the beginning and tried it on the team members. It''s just because the power level of the group''s five element psionic is not low, he stopped before transmitting the power energy higher than this attribute. I didn''t expect that it was just a step away from the hard way.


    It is said that the discovery of this point in Chuanyuan base was also unexpected. It was a certain fire power person who absorbed too much five elements of the earth system and then awakened the earth system power, which attracted Chi Hui''s attention and began to study in this direction.


    Duan Yin''s five element powers are not many, but the world knows that the Xuanyuan family is famous for their five element powers. This method is more valuable to them than borrowing manpower and crystal nucleus. Naturally, there is no reason to shirk.


    Only then did Duan Yin send someone out, and the guests from overseas came here.


    "Maple people?"


    Hou Ying surprised several people.


    They thought they were neighbors of China, but they were guests from across the ocean. The land is full of zombies, and the sea is full of zombies. Under such circumstances, it''s hard to imagine how they came to this place.


    Duan Yin said: "I was also shocked at that time. There is an old man in their team. His powers are very special. They are exclusive powers. For wind and rain, ability attacks are unconditional rebound out. So they came by air, directly from the sea. It''s really admirable. They''ve been in China for some time, and they don''t know who they are. When they hear about us and feel that we are the most powerful, they just come to our door


    "But I''m very interested in the technology they offer to trade."


    Overseas people who are more dependent on thermal weapons have devoted themselves to the research of power weapons earlier than the Pearl River base.


    What they brought this time is also a core technology in their research on psionic weapons.


    Duan Yin briefly introduced the technology of the other party as a payment transaction. Of course, the core part has not been mentioned, but from the video materials they shot, it can be seen that this technology can be put into use even if it is immature.


    This technology, just related to the old man''s special ability, is the base repulsion system.


    The area of churches and residential areas occupied by their base is half the size of the Pearl River base. With this technology, they can successfully exclude wind and rain and light power attacks from the protection circle, which is the reason why their base can persist for so long after the end of the world.


    Hearing this, dongfangbai was surprised: "since they have a magic weapon to protect their lives, what else do they want to ask us for help?"


    Duan Yin said with a smile: "listen to me, you will be very interested."


    Duan Yin motioned for him to be calm, and then talked about the plight of maple leaf people - Zombie tide. The zombie tide that has besieged them for three months but refused to disperse is an organized operation to encircle the human base.


    "According to them, their chief zombie - can talk."
