Su Feifei didn't expect Mo Lan to enter the role so quickly after not seeing her for a day. She believed that in the near future, Mo Lan would be as good as Li Yunqi, and maybe even surpass Li Yunqi's ability.

In about half an hour, Mo Lan and several of his subordinates quickly vacated a new house, Li Yunqi patted Mo Lan's shoulder and said: "Little Mo Mo, it's really good, you entered so soon role, I believe that one day you will be better than blue."

Tieguaiqi heard that the room was ready, and walked slowly into the room with staggering steps. He had to say that the simple room in front of him really suited his taste. It was basically a large white wall, not too much. Decoration, the soft bed in the room is suitable for him, and he must take this bed with him when he leaves.

"Young Master Mu, the conditions I mentioned are basically satisfied, and the construction can start next. Take me there first to see the secret base you need to design."

Seeing that Tieguaiqi was finally not picky, Su Feifei took Tieguaiqi to the backyard in a calm manner. Shopkeeper Li and others thought that Su Feifei had hidden some secret weapon, but they didn't expect to take them directly to the hut.

"This is the area I want you to design. You can design a few pipes or one pipe as long as you can design it. It depends on your workload. Look at the design drawings and see what you don't understand. I can give you one by one now. Make it clear."

Tieguaiqi looked at the abandoned pond in front of him, looked at Su Feifei with disgust and said, "Your efforts are completely wasted, what role can this abandoned pond serve?"

Seeing everyone's suspicious eyes, Su Feifei walked back to the kitchen, fetched a bottle and unscrewed the cap, then reached out and put the bottle in the abandoned pool, and took it out about a minute later.

"Xueyi, go find me a torch."

Hearing Su Feifei's instructions, Xue Yi let out a "whoosh" and went straight to the kitchen, and then brought out a lit wooden root and held it out, "Master Mu, here it is!"

Su Feifei unscrewed the bottle cap, and saw that the empty bottle was on fire. Seeing this spectacle, Tieguaiqi looked at Su Feifei excitedly and asked, "What is this? How did it catch fire?"

"This is called a biogas digester. The biogas in it may be used to cook vegetables and start a fire. I won't explain the principle here to you, because you can't understand it. Senior Tieguai Qi, just follow my drawing. It’s fine to start the construction with the design, if you don’t have enough manpower, you can go directly to shopkeeper Li, and I won’t interfere in this matter.”

When everyone heard Su Feifei's explanation, they wanted to vomit blood. This young lady is too powerful to know so many things they don't know.

Feng Chen didn't expect that Su Feifei could invent these things. Seeing the woman in front of him getting more and more mysterious, he suddenly felt powerless, and he seemed to be more and more unworthy of her. It seemed to outsiders that she was admiring him, but in fact, the incompetent The humble woman is far better than everyone imagined.

"Okay, I'll try my best, but I still have one request. After five days, I will move the bed inside, and every time I come here, I must eat for free."

Su Feifei nodded and said: "No problem, come to eat once every five days, free of charge, don't make any more conditions, because we have cooperated many times, I am willing to leave this matter to you."
