Human research has been deepening, but the resistance of evolutionary insects is also improving. The anthelmintic drug that was improved at the base in June has become worse against the evolution of insects.

Unable to let the flies that spread germs circulate around the sick wolf, Xia Qing went back to the house to bring an insect trap, caught the evolved big flies, and threw them all into the fire, and then took out the window screen from the tool room, and neatly installed an openable and closable insect-proof screen door with a magnetic stripe for the sheep shed.

When Xia Qing was tightening the screws on the door, she heard Kuang Qingwei ask her about food storage through the lord's walkie-talkie.

"Xia Qing, are you there? What do you think about digging a cellar and putting potatoes? ”

After the lords returned the small potatoes to the safe zone, they did not sell the potatoes at the price set by the safe zone, but tried to store them.

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

Shi Qian asked, "Xia Qing, if you dig the cellar, how to solve the ventilation problem?" ”

Qi Fu is recuperating from his injuries, and his online time is not fixed. For construction-related issues, Xia Qing, who is the deputy leader of the construction team in the security zone, is also very knowledgeable, so he has become the object of everyone's consultation. However, Xia Qing will not be online for a long time, and after catching her, everyone hurriedly asked.

This Xia Qing has already thought about it, and Xia Qing replied, "You can install a ventilation fan, or you can leave a vent and use a blower to blow air in regularly." ”

Cong Qingwei felt that it was inappropriate, "Let's not talk about how many points there are for ventilation fans and blowers, these two things have to use electricity, our solar panels have been smashed by hail, how can there be ventilation fans for electricity." ”

Concord Qingwei has always spoken with a lot of water, and he can only believe three points at most. If his solar panels are all smashed, how does the walkie-talkie be charged?

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 batteries 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 exhaust fan with a battery for experiments, and the test results showed that the ventilation effect after installation was of course better than that without ventilation, but the humidity and temperature were more difficult to control.

Therefore, it is feasible to install exhaust fans to ventilate at regular intervals every day or every other day.

In order to keep it secret, Xia Qing did not go through the normal transaction process with Zhong Tao, but said hello to Hu Zifeng, and exchanged the yellow light vegetables in the greenhouse with the No. 1 territory. There are many people in the No. 1 territory, and the consumption of vegetables and grains is large, and most of the yellow light vegetables that Xia Qing planted in the farmland vegetable greenhouse were sold to the No. 1 territory, and the small half were sold to Zhong Tao and Zheng Kui.

Tan Junjie hadn't traded vegetables with Xia Qing in the past two months, and Xia Qing speculated through many signs that he should be the lord of the fifteenth territory.

Shi Qian continued, "Xia Qing, the ventilation fan on the top of the underground building in our safety zone that is rotated by the wind does not use electricity?" ”

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

Cong Qingwei felt that it was inappropriate, "That kind of no, it's too big, too conspicuous." ”

The place where food is stored, of course, is as hidden as possible.

Zhao Ze, who did garden construction before the disaster, joined the discussion, "You can use the same ventilation method as in rural cellars in the past, either not blocking the mouth of the cave or cellar, or using pipes to communicate with the outside." Although this will make the storage effect almost meaningless, we don't have much food in the first place, and we don't need to store it for long. ”

Everyone followed suit, but there wasn't much food to store in the nearby territories, and I was afraid there was only one territory on Four.

Zhao Ze asked Xia Qing, "Xia Qing, are you digging a cellar or a cave?" ”

Xia Qing replied calmly, "There are many hillsides in my territory, and I plan to dig caves. Does Brother Zhao know what kind of place to dig a cave? ”

Zhao Ze replied simply, "Of course, it's a hard and dry place, it often rains here, and digging a cave for waterproofing is a problem." When will the third brother come back, I want to ask him if there is any good way to save food. ”

Zhang San is so greedy, there must be a way to preserve food, but I don't know how cost-effective. Zhang San, who has been away from the territory for ten days, is an important person that everyone has to recite several times every day. He's not there, and everyone always feels unsteady.

Just when Xia Qing was guessing what could keep Zhang San for so long, and he didn't even have time to come back to enjoy the green light meat, the phone in his pocket began to vibrate.

The caller was Yang Jin, he called himself, there must be something urgent, Xia Qing immediately connected.

"Just now, the Shufeng team found Xu Juan of the Dongyang team and Daniel Zhang of the construction team and asked them to install solar panels for you."

Xia Qing was very low-key when she was in the safe zone, and her interpersonal relationship was very simple. Xu Juan and Daniel Zhang are still in the safe zone, and the two people who have the most contact with her before.

Daniel Zhang is the only ordinary person among the four captains of the construction team of the Hui San Base. He is in charge of four squads, each of which has a vice-captain, and Xia Qing is one of his four vice-captains.

Before the natural disaster, Daniel Zhang was engaged in construction in this place, and he had some connections, and after the natural disaster, he relied on his previous relationships and his own strength to steadily occupy the "fat shortage" of the captain of the construction team.

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

Xia Qing went to the construction team to know that with Daniel Zhang, it was too late for her to change teams. Because the construction team has a conventional rule: if Xia Qing quits Daniel Zhang's construction team, other construction teams will not want her again.

The reason why Xia Qing was reluctant to work with Daniel Zhang was because he was lustful.

Although Daniel Zhang will not force women, but after the natural disaster, there is a lack of food and clothing, and many people take the initiative to stick to Daniel Zhang for food and materials, and Daniel Zhang's wife has made trouble with him for this.

In the first month of Xia Qing's joining the construction team, Daniel Zhang's wife ran to the construction site to make a fuss. After she couldn't explain it, Xia Qing directly lifted her up and threw her sideways in the sand, and she was honest.

Daniel Zhang remembered Xia Qing's father's life-saving grace, and did not embarrass Xia Qing because of this, but he was afraid that his wife would make trouble again, and he did not dare to take care of Xia Qing more.

Xia Qing avoided suspicion and only maintained necessary working contact with Daniel Zhang. Later, Xia Qing was able to become the vice captain, relying on her strong ability as a strength evolutionary.

Xia Qing didn't expect that he would be worthy of such a big effort from the Shufeng team, "Xu Juan is an auditory evolutionary, Daniel Zhang is an ordinary person, and they can't find anything when they come in." Does Team Yang know the plan of the Sufeng Clan? ”

"They should have monitoring devices on two people, or sprinkle drugs that can cause a strong reaction in the evolved animals." Yang Jin paused and continued, "Because the latter is easy to find out, the former is very likely. They ask Daniel Zhang or Xu Juan to ask you about pangolins, and then ask brain domain evolutionaries to analyze changes in your facial expressions and voice to determine whether you are telling the truth or a lie. ”

Xia Qing knew that the Brain Domain Evolutionary was perverted, but he didn't expect it to be perverted to this extent, "Team Yang, can they really see it?" ”
