Ans said he wanted to get a batch of energy shields for Zhang Chengchuan, but he did get them. There are dozens of these energy shields. Although it is only a very common first-generation energy shield, the attacks that can be resisted are very weak for the interstellar age, but it can withstand any physical attack on the earth in the 1960s.

Zhang Chengchuan took the lead in putting energy protective shields on his daughter-in-law and parents, and then gave one to his sister's house, father-in-law's house, grandparents' house, and others.

The shape of this energy shield is different, some look like a ring, some look like a bracelet, and some look like a necklace.

Chen Xiayue was wearing a bracelet. She didn't like to wear necklaces, earrings or anything, nor did she like to wear rings. Bracelets are only the result of taking second place, otherwise she really doesn't want to wear any jewelry.

"For a ring, I want to design one for you." Zhang Chengchuan said, looking at his wife's left hand wearing a bracelet.

Because she often uses her right hand, Chen Xiayue, who was wearing the bracelet on her left wrist, looked at him for fear that wearing the bracelet would affect what she did.

"Neither of us have a pair of rings. I want to hold you firmly and trap you. Let you always belong to me, and I will always belong to you." Zhang Chengchuan held his daughter-in-law's hand and put it on her finger. Gently branded a kiss.

"But I don't like wearing rings." Chen Xiayue's eyes were gentle, and she said with a smile on the corner of her mouth, her words were very damaging to the atmosphere.

"Don't like rings?" Zhang Chengchuan looked at his daughter-in-law, why didn't he like jewelry?

"I don't like jewelry. If it weren't for the fact that this bracelet feels like warm jade, it feels a little warm to the touch, and I don't like wearing it." Chen Xiayue doesn't like any jewelry, the most important thing is that she doesn't like the feeling of being cold, and she doesn't like metal. The feel against the skin.

"You make me feel so unfulfilled, daughter-in-law, I was talking sweet words to you, but you said that you like wearing a ring, and the emotions that I had brewed were gone." Zhang Chengchuan squeezed her hand helplessly and "complained." "road.

"That can't be helped. If you don't say that I don't wear the ring after you've finished it, wouldn't it waste your heart even more?" Chen Xiayue said with a smile.

Zhang Chengchuan leaned over to her forehead and said, "So, daughter-in-law, what do you like? Why don't I design a set of kitchen utensils for you? Or make you a set of pharmaceutical tools."

Zhang Chengchuan thinks this is pretty good. His wife will use a set of kitchen utensils or pharmaceutical tools often, and if her wife doesn't like wearing rings, she won't make them.

"Okay." Chen Xiayue thinks this proposal is good, she likes a set of kitchen utensils or a set of pharmaceutical tools, more than rings and jewelry.

"I don't know what's going on with you. Others like gold and silver jewelry and all kinds of jewelry, but you don't like it. You are a little difficult to support, daughter-in-law." Zhang Chengchuan "complained" with a smile.

"I'm still calling it difficult to support? Gold and silver jewelry are rare, isn't it just right that I don't like it?"

"For me, gold and silver jewelry is easy to get, but other things you like are more difficult." Zhang Chengchuan sighed.

"Thank you for your hard work." Chen Xiayue said with a smile.

"Who asked me to be your man?" Zhang Chengchuan kissed her and said.

After having the energy protection cover, Zhang Chengchuan finally felt relieved, and let his daughter-in-law and father and mother stay at home. He and Lu Zhanguo went into the mountains for training.

In the south, especially in Yunnan and Guangxi, there are tropical rain forests, and it is more dangerous to go into the mountains for training. No one knew what was in the forest. There were many poisonous snakes, poisonous insects, pythons, and even some large beasts, which were very dangerous.

It's just that the forest on the side of the Canal Brigade is not that dangerous. After all, it is a place where people gather and live. The nearby forest has already been trodden all over, and it is unlikely that there will be many large beasts.

There are wild boars at most, and there are very few large beasts other than wild boars. Tigers, leopards, bears, and bison are very few.

But wild boars alone are a bit dangerous. After all, wild boars are also very powerful.

Zhang Chengchuan and the others did not train in the forest near the Canal Brigade, they went to the mountains. Zhang Chengchuan went into the mountain with the information of the oil detector he was researching, and did not intend to keep the things at home.

Lu Zhanguo and the others did not object. After all, they went into the mountain with Zhang Chengchuan, and there were no guards at home. If those people wanted to come and steal things, it would be very easy.

If Zhang Chengchuan brought the data into the mountain, the security of the data would be even higher.

Zhang Chengchuan went into the mountain, and when Chen Xiayue stayed at home, the uncle's biogas digester was ready for use, and the digester could already produce biogas.

"Is it alright?" Chen Xiayue was also surprised, how long has it been? Has it been half a month? Is it possible to generate biogas already?

"Yes, the uncle's biogas lamp can really be used. I heard that my brother planned to turn on the light last night, but I didn't expect it to come on. Although it was only on for a few minutes, it was still on." Hu Xiaofang excitedly Holding Chen Xiayue's hand, he said.

"This is really great." Chen Xiayue said with a smile, the digester can be used, that's really great.

Although she said that she has great confidence in Zhang Chengchuan, some things must be successful after a few or many failures. Even though Zhang Chengchuan's biogas digester was learned from later generations, she was worried that the digester would not work.

Well now, the lights can really be lit after the biogas digester produces biogas, so Zhang Chengchuan's painstaking efforts have been recognized.

As for her house in half a year, she can also build a biogas digester. In addition to the biogas lamp, she will also need a biogas water heater.

If biogas cannot be used in water heaters, Zhang Chengchuan can be tossed with solar water heaters. It is still comfortable to take a hot bath in winter, but she is too lazy to boil water.

Chen Xiayue and Hu Xiaofang went to the uncle's house to chat with other people. Everyone in the daytime must be reluctant to turn on the lights. Although this biogas lamp does not need to spend money, the biogas is also used a little bit, so it must not be wasted.

Everyone just got together to talk, and of course the topic of discussion was Zhang Chengchuan. Chatting and chatting must be asking Chen Xiayue, can you ask Zhang Chengchuan to help build a biogas digester?

"Okay." Chen Xiayue smiled, "But Ah Chuan has no time. Didn't he go into the mountains with those military comrades recently? He won't be back for a while, so he has to go for a few days, if it's a little longer, maybe It will take ten days and a half to come back.”

"If you are in a hurry, you can ask some cousins ​​to help you." Chen Xiayue pointed to the cousins ​​who built the biogas digester with Zhang Chengchuan and said, "The biogas digester at the grandparents' house was built by everyone. How to build it? Everyone is experienced, and without Achuan, a few cousins ​​must be able to build a biogas digester, right?"
