Xia Qing is not sure whether the protective equipment made by snake skin with advanced hardness is easy to use. She can only deeply feel that the flesh of this snake is really hard, only lower than that of the hardness evolved yellow light soybeans harvested by Xia Qing.


    Xia Qing had only one feeling after drinking this meal: toothache.


    She felt that the weak stomach of the sick wolf may not be able to digest such hard meat and cannot draw nutrients from the snake meat. If you can''t make porridge, you can only make it into meat paste and cook it into meatballs or steamed meat before eating.


    The blades of the noodles grinder she exchanged from the Territory Management Department will definitely not be able to beat such hard meat. Just as Xia Qing was thinking about whether to use the price of being scolded and asked Uncle Huo to help her build a special meat grinder, Zhang San called.


    "Xia Qing, can the meat bite? I have a small meat grinder here, I will send you one?"


    Where to find Blue Star high-quality idols, Hui San Base No. 7!


    Xia Qing was overjoyed and immediately thanked, "Thank you, Brother Third. I cooked a pot of meat porridge, and my teeth hurt so much that my teeth were hurt. I was thinking of a solution, and your phone call came over."


    Zhang San was in a good mood and a very kind voice, "You can eat 100 kilograms of this giant python meat this winter. No matter how much you eat, you cannot absorb the energy inside. You can exchange the excess snake meat for those in need. Eating this meat to ordinary evolvers or ordinary people who have not eaten advanced evolutionary meat will be more obvious. The effect of improving its immunity and raising evolutionary abilities will be more obvious."


    Xia Qing immediately asked, "Does the third brother still need it? If you need it, take some more."


    Zhang San smiled, "I''m enough here. Try not to let too many people know the source of snake meat. There is a risk of killing snakes in that place. It is not only the danger of catching snakes, but also the possibility of being used by those who are interested in breeding and killing snakes in large quantities."


    "I understand, thank you for your reminder." After Xia Qing thanked, he asked about the big cooling, "I heard that the lowest temperature this winter will drop to minus 30 degrees Celsius. Third brother, can our wheat seedlings hold on?"


    Zhang San responded, "According to predictions, this winter will indeed be colder than in previous years. To what extent it will drop depends on the amount of snowfall. The wheat species I gave you are bred with wheat from a highly winter-based evolutionary variety. It is definitely no problem to resist minus 20 degrees Celsius. If the temperature is low, you need to take measures to keep warm."


    Zhang San did not tell Xia Qing how to keep wheat warm. It should be that his warming measures were not practical for ordinary territory.


    In the afternoon, when Xia Qing went to the greenhouse to plant leek roots, she asked her allies about keeping the farmland warm in winter.


    Qi Fu introduced that he should put down the greenhouse to prevent rain and wind and keep warm at night. Shi’s mother mentioned a new method, “Before the natural disaster, when our villagers set up small sheds to grow vegetables in winter, they would dig cold-proof ditches around the greenhouse, put foam boards or polystyrene boards inside, and then fill them with sawdust, weeds, straw and other insulation materials, compact them, and then cover the soil and seal the ditch. It is said that the ground temperature in the shed can be increased by three to five degrees.”


    Qi Fu''s wife Yuan Yan immediately followed, "I remembered this when my sister-in-law mentioned it. When we ran a cart to a cold province in the north to pick up vegetables, we heard people who planted greenhouses there mentioned this method."


    Zhao Ze asked, "It''s the year of natural disasters. Are there still factories producing foam boards or polystyrene boards? I don''t know how many points per kilogram."


    Kuang Qingwei is online, "I''ll go and inquire and tell everyone later."


    Xia Qing asked, "How wide and deep are this kind of cold-proof trenches dug?"


    Shi’s mother replied, “It seems to be forty centimeters wide and half a meter deep.”


    Li Si suddenly went online, "The depth of the cold-proof groove is not a fixed value, it is positively correlated with the depth of the permafrost layer in this area, and it is about 10 centimeters deeper than the permafrost layer."


    Xia Qing quickly asked, "Sister Four, how thick are the permafrost here this winter?"


    Li Si''s voice was still deserted, as if the quarrel between Shan Ying and Zhang San in the morning had no effect on her. "Seasonal permafrost is a permafrost formed by the temperature below zero in winter. The thickness of the permafrost is related to the temperature. The lower the temperature, the thicker the permafrost layer."


    "I don''t have the Hui San base here. The data on the thickness of the permafrost in winter in previous years. According to the latitude, the permafrost in Hui San base should be two to three centimeters thicker than that of Hui One Base. However, our territory is surrounded by mountains on the east, north and west sides. The thickness of the permafrost should be one to two centimeters thinner than other areas, so it should be equivalent to that of Hui One Base."


    So, what is the specific thickness?


    Xia Qing asked very clearly, "Sister Four, what was the minimum temperature at Huiyi Base last winter? How thick is the permafrost layer?"


    Li Si directly gave "13 degrees below minus 45 cm." Qi Fu followed Xia Qing closely, "Sister, the soil layer here is about the same thickness, right? In other words, will the soil layer here be frozen in winter?"


    "Yes." Li Si gave a positive reply this time.


    Zhao Ze asked, "Sister Four, the soil layer is frozen, won’t the wheat and rapeseed be frozen to death?"


    Li Si replied, "No, the wheat variety you received in spring is M-11, which is a strong winter evolutionary variety that can withstand the low temperature of minus fifteen degrees."


    Xia Qing concluded, "So, if we dig a cold-proof trenches, do we need to dig through the soil layer?"


    After Li Si gave a positive reply, Kuang Qingwei went online, "Everyone, it is said that this winter will be very cold. The prices of foam boards and polystyrene boards doubled compared to half a month ago, and there is no stock yet, so you can only pre-order it. It is not suitable for us to use in the field. Brother Ying, you should buy some and stick them on the wall."


    People in Territory No. 15 live in iron houses, which have poor anti-cold and warmth effects. Yue Haiying responded, "Sure, I''ll find a way to see if I can get some back."


    "Even if you don''t use foam boards, digging cold-proof trenches is definitely better than not digging. I plan to dig them." Qi Fu has always spared no effort in farming.


    Zhao''s mother followed her farming expert, "I''m digging too. This fall we dry a lot of hay, enough to fill the ditch."


    "I''ll dig too." Although there are few people in Xia Qing''s territory, she has micro-tillers, and the speed of digging of trenches is not necessarily slower than that of others.


    After planting leeks and irrigating them with spring water, Xia Qing carried the basket and took the sheep and the sick wolf to climb into the North Buffer Forest to cut the toon bells.


    “What—”


    This big toon tree with all its leaves is the treasure of the Sheep Boss. Seeing Xia Qing climbing up the tree and taking out the long branches and shears, Boss Yang screamed, feeling a little uneasy.


    It thought that Xia Qing would hurt Dachun Tree.


    "It''s not about cutting down trees, it''s about cutting the fruits of the toon tree, that''s it." Xia Qingkaka cut off a few strings of toon bells to let Boss Yang understand what she was going to do.


    Boss Yang was no longer nervous when he saw Xia Qing just cutting small branches to play with, he immediately stopped being nervous. After coming forward to sniff the toon bells, she found that she couldn''t eat it, and she lost interest and went to eat the dried toon leaves on the ground.


    The sick wolf picked up a string of spring bells and put them in the basket, looking up at Xia Qing.


    Xia Qing, who was standing on the tree, immediately praised, "The second child is so great, the second child is so amazing. Yes, I put all the cuts in the basket. We want to take them home."


    The sick wolf grinned, hahaha.


    Boss Sheep, holding the leaves in her mouth, raised her head and looked at it a few times, and continued to lower her head to cook.


    “Sister Qing—”


    Xia Qing, who was standing on the big toon tree, heard the shout and turned around and saw Hu Zi standing outside the north gate of Territory No. 3 with a bicycle. (End of this chapter)
