The villain heroine is forced to farm

Chapter 355 Have you ever seen a circus?
Yan Xun didn't let Ruan Zhenzhu leave, "Come and tell me about your biogas being used as fuel to make a fire!"

Ruan Zhenzhu glanced at Li Zibai and slumped down from the wall.

Li Zibai knew what she was going to say, and it might not be rumored, but he couldn't move, wanting to hear what she could say.She is only nine years old, so she is not only talented in medical skills.

Ruan Zhenzhu didn't shy away from it, because he might not understand it, and he might not be able to figure it out, even she can't help it for the time being!
"The gas generated by the decay of dung is called biogas. If there is a lot of biogas, it can be ignited. I want to build a biogas tank and burn the biogas for cooking, so there is no need to burn firewood, and there is no ashes! Biogas can also be used to light lamps without electricity! "

Yan Xun was very interested in her whimsical ideas, and even her wife sincerely asked for advice and discussed with her.

It is rare to meet an old pedant who is interested in these things, and the other party is not stupid, and Ruan Pearl is not stingy, so he explained it to him.

After hearing this, Yan Xun was shocked.

Li Zibai never expected that her ingenuity would reach this point, suppressing her shock, she pointed to the biogas lamp on the blueprint, "This lamp is facing downwards, so it might be on?"

"It can be lit! There is a glass cover on the outside. This lamp is ejected from the ejector to burn. At the moment of burning, the inner gauze cover will shrink into a white ball, and the lighting energy emitted is sufficient in methane, which is equivalent to a thousand torches." Ruan Zhenzhu sketched out the general structure of the biogas lamp.

Li Zibai: I don't understand!
Yan Xun and Yan Wei didn't quite understand either.

Ruan Zhenzhu was silent for a while, "Have you ever seen a circus? The one that breathes fire?"

"Oh~~" The three of them immediately understood, what she said about spraying methane was like a fire-breathing trick, the ejector was probably equivalent to a person's mouth?

"Can this thing be made?" Yan Xun asked hastily.

"It can't be done now, the cement materials for the first step are not available yet!" Ruan Zhenzhu shook her head.Yu Wanduo is so useless!Up to now, no decent cement has been produced!She built the yard in the same old way.

Yan Xun was a little disappointed, he wasn't very interested in cooking with biogas, but he was particularly interested in the biogas lamp, which was as bright as day and could withstand a thousand torches!Because he himself has eye problems, he can't see clearly at night. Now he can only read and practice calligraphy during the day.

Ruan Zhenzhu knew that his eyes had cataracts. All she could do was to remove the cataract lens, but she had to implant an artificial lens to restore her vision.At present, there is no such high technology as artificial crystals, so he can only block them.

After staying for a long time, Ruan Zhenzhu also had a lot of things to do, so she got up to leave.

Li Zibai then left and came out, looked at her, lowered his head and hurried to catch up, "Pearl!"

"I changed my name!" Ruan Zhenzhu gave him a sideways look.

Thinking of her new name, Li Zibai frowned, but said, "Ba Ba!"

"What are you doing?" Ruan Pearl asked with a smile.

A strange feeling rose in Li Zibai's heart, but he suppressed it quickly, "I have doubts in the future, can I ask you?"

"No!" Ruan Zhenzhu still has to teach Ruan Tonghua, Ruan Baoting, Luyi, Hongqin, Qingdai, and Zisu mathematics, and Ah San Ah Leng and the others in chemistry.

Li Zibai was stunned for a moment, and also expected that she would refuse.Before asking for a teacher, she refused straight away.

"The master said that you are very talented, and you see it differently than others. I won't waste much time!"

"You're wasting my time right now!" Ruan Zhenzhu gave him a white look.

Li Zibai wanted to say more, and out of the corner of his eye, he saw the gate next door to her house, Mo Yan was sitting there with dark eyes, looking at him.
