Human research has been in-depth, but the drug resistance of evolutionary insects is also increasing. The base''s modified antiworming medicine in June has worsened its effect on evolutionary insects.


    The flies that spread the germs could not be allowed to circumvent the sick wolf. Xia Qing went back to the house to take the insect net, put the evolutionary flies net, threw them all into the fire, and then took out the window screen from the tool room, and simply installed a open-closed insect screen door for the sheep shed with magnetic strips.


    When Xia Qing''s debugging door screws were tight, he heard Kuang Qingwei ask her about food storage through the lord intercom.


    "Xia Qing, are you there? How do you think it''s like digging a cellar to put potatoes?"


    After each lord sent the remaining potatoes back to the safe area, he did not sell the potatoes at the price set in the safe area, but instead found a way to store them.


    Xia Qing didn''t mention that he had dug two cellars and pressed the walkie-talkie button, "If you can do a good job of insects, rats and moisture-proofing, I think you can give it a try."


    Shi Lu asked, "Xia Qing, if you dig a cellar, how can you solve the ventilation problem?"


    Qi Fu is recovering from his injuries, and the online time is not fixed. Regarding construction-related issues, Xia Qing, who is the deputy captain of the construction team in the safety area, is also very knowledgeable, so he became everyone''s consulting target. But Xia Qing won''t be online for a long time. After she caught her, everyone asked quickly.


    Xia Qing has already considered this, and Xia Qing replied, "You can install a ventilation fan, or you can leave a vent and use a blower to blow in regularly."


    Kuang Qingwei felt that it was inappropriate. "I won''t talk about the points of the ventilation fan and the blower. Both of these things have to be powered. Our solar panels have been smashed by hail. How can we use ventilation fans?"


    Kuang Qingwei has always been very humid in his speech, and he can only trust three points at most. If his solar panels are broken, how do you recharge the walkie-talkie?


    Xia Qing continued to reply, "If it is a small cellar, you can use a small exhaust fan as a ventilation fan. I remember that there is an exhaust fan driven by a battery in the safety area."


    In the cellar in the deserted village on the southwest side of the No. 3 territory, Xia Qing installed a small battery exhaust fan for experiments. The test result was that after installation, the ventilation effect was of course better than non-ventilation, but the humidity and temperature were more difficult to control.


    Therefore, it is feasible to install an exhaust fan to ventilate regularly every day or every other day.


    In order to keep it confidential, Xia Qing did not go through the normal trading process with Zhong Tao, but said hello to Hu Zifeng and exchanged the yellow-light vegetables in the greenhouse with the No. 1 territory. Territory No. 1 is crowded and consumes a lot of vegetables and grain. Most of the yellow-light vegetables grown in the vegetable greenhouse in the farmland were sold to Territory No. 1, and the smallest was sold to Zhong Tao and Zheng Kui.


    Tan Junjie has not traded vegetables with Xia Qing in the past two months. Xia Qing speculated through many signs that he should be the lord of Territory No. 15.


    Shi Ji continued, "Xia Qing, does the ventilation fan rotating by the wind on the roof of the underground buildings in our safety zone do not use electricity?"


    Xia Qing also considered this, but gave up, "It''s not using electricity, but it has to be installed in an open air ventilated place."


    Kuang Qingwei felt that it was inappropriate, "That kind is not good, it''s too big and too conspicuous."


    Of course, the more hidden the food is, the better.


    Zhao Ze, who was doing garden construction before the natural disaster, joined the discussion, "We can use the ventilation method of the rural cellar in the past, either not blocking the holes of the caves or cellars, or using pipes to connect to the outside. Although doing this will cause the storage effect to be a bit bad, we don''t have much food at all and we don''t need to store it for long."


    Everyone followed suit, but there was not much food in the nearby territories, so there was probably only one territorial No. 4.


    Zhao Ze asked Xia Qing, "Xia Qing, are you digging a cellar or a cave?" Xia Qing replied calmly, "I have many hillsides in my territory, and I plan to dig a cave. Brother Zhao knows what kind of place to dig a cave?"


    Zhao Ze simply replied, "Of course it''s a hard and hard place. It often rains here, so digging caves to prevent water. When will the third brother come back? I want to ask him if there is any good way to preserve food."


    Zhang San is so greedy, and he must have a way to preserve food, but he just doesn’t know how cost-effective it is. Zhang San, who has been away from the territory for ten days, is an important figure that everyone has to say a few times every day. Everyone always feels uneasy when he is not here.


    Just as Xia Qing guessed what could hold Zhang San for so long and didn''t even have time to come back to enjoy the green lamp meat, the phone in her pocket began to vibrate.


    The caller was Yang Jin. He called himself and there must be something urgent, so Xia Qing answered immediately.


    "Just just now, the Sufeng team approached Xu Juan from Dongyang team and Zhang Yong from the construction team and asked them to install solar panels for you."


    Xia Qing was very low-key when she was in the safe area, and her interpersonal relationships were very simple. Xu Juan and Zhang Yong are the two people who are still in the safe zone and have contacted her the most before.


    Zhang Yong is the only ordinary person among the four captains of Hui''s three base construction team. He has four teams in charge, each team has a deputy captain, and Xia Qing is one of his four deputy captains.


    Zhang Yong was in this area before the natural disaster. He had some connections. After the natural disaster, he relied on his previous relationships and his own strength to firmly occupy the "fat and shortage" of the construction team captain.


    Xia Qing''s father saved Zhang Yong''s life in the beast tide. Zhang Yong was grateful, so when he learned that Xia Qing had applied to join the construction team, he pulled her into his team to take care of her.


    Xia Qing went to the construction team and found out that she followed Zhang Yong. It was too late for her to change teams. Because the construction team has a conventional rule: if Xia Qing withdrew from Zhang Yong''s construction team, other construction teams will not want her again.


    The reason why Xia Qing is unwilling to work with Zhang Yong is because he is lustful.


    Although Zhang Yong would not force women, he was short of clothing and food after the natural disaster. There were many people who took the initiative to stick to Zhang Yong for food and supplies, and Zhang Yong''s wife had a lot of trouble with him for this.


    In the first month Xia Qing joined the construction team, Zhang Yong''s wife ran to the construction site to make a big fuss. After the explanation was not understood, Xia Qing directly lifted her up and threw her into the pile of sand before she became honest.


    Zhang Yong was thinking of Xia Qing''s father''s life-saving grace, but he did not make things difficult for Xia Qing, but he was afraid that his wife would make trouble, so he did not dare to take care of Xia Qing more.


    Xia Qing avoided suspicion and only maintained necessary work contact with Zhang Yong. Later, Xia Qing was able to become the deputy captain because of her powerful ability as a power evolutionist.


    Xia Qing didn''t expect that he would be worth the effort of Sufeng Team. "Xu Juan is an auditory evolutionist, Zhang Yong is an ordinary person, and they can''t find anything when they come in. Does Team Yang know about Sufeng Team''s plan?"


    "They should install monitoring equipment on two people, or sprinkle drugs that can cause strong reactions from evolutionary animals." Yang Jin paused and continued, "Because the latter is easy to detect, the former is very likely. They asked Zhang Yong or Xu Juan to ask you about pangolins, and then asked brain evolvers to analyze the changes in your facial expressions and voices to determine whether you are telling the truth or lies."


    Xia Qing knew that the brain domain evolvers were perverted, but he didn''t expect that they had become so perverted. "Captain Yang, can they really see it?"
