"Your plan is well written, but don't take care of your body next time." Zhao Zheng whispered behind Yaoxing now.

Plan? Oh, and the plan isn't finished yet. Yao Xing wanted to walk to the desk, but forgot that the back of his neck was still in Zhao Zheng's hand, and he was carried back as soon as he took two steps forward.

"I'm almost done with my plan, I'll finish it." Yaoxing still wanted to get rid of Zhao Zheng's hand, struggling to get Zhao Zheng to let go.

"I'll finish writing the rest, and you'll be honest." Zhao Zheng suddenly increased the strength in his hand, and Yao Xing let out a "Ah~" sound in pain.

"How long have you been here?" Yaoxing thought that Zhao Zheng had been here for a long time before people woke him up!

"Just arrived," Zhao Zheng said in a light tone

Zhao Zheng won't lie, but if he just arrived and completed the plan that had troubled him for a long time yesterday, would he look like a fool?

Sure enough, people have to die more than people, and goods have to be thrown away!

"Show me your plan," Yao Xing held out a hand towards Zhao Zheng behind him.

Yes, it's Zhao Zheng's plan, Yaoxing doesn't want to admit that he worked hard for half a night, and the plan that was quickly completed by Zhao Zheng is his own, so let's just treat it as if it's nothing!

Yao Xing also glanced at the plan, and wanted to take the bamboo slip in his hand to himself, why was he so stupid. The greenhouse was found, and I thought of planting medicinal materials, but I couldn't think of using the greenhouse to grow medicinal materials. The investment in greenhouse farming is too large, but it is a trivial matter to grow medicinal materials in the greenhouse!

"What is this greenhouse?" Although Zhao Zheng completed Yaoxing's plan, he was not completely familiar with the contents of it. The greenhouse is also used because Yao Xing calculates the time it takes for the greenhouse to mature twice a year on the abandoned bamboo slips on the side.

Yaoxing is interested, look, it's still a little useful to cross by yourself, there are places that the ancients can't compare!

"It's to grow medicinal herbs in the house, and the walls of the house are made into a double layer, and there are pipes in them, and if you burn a fire, the walls will become hot. When the temperature reaches a certain level, there is also a growth rate in winter and summer. "Yao Xing always has one of his few knowledges, and he will tell the principle of the greenhouse.

"And how do you make this greenhouse?" Zhao Zheng was pleasantly surprised, isn't this the way to increase grain production!

"Red bricks and cement can be made, but the details still need to be practiced by Mr. Su Han. If it goes well, it can be built in two months. Yaoxing roughly calculated the time it would take for the red bricks and cement to be transported and the greenhouse built.

"Is it feasible to grow food in a greenhouse?" Zhao Zheng's eyes were already excited that couldn't be hidden.

But Yao Xing had to pour a basin of cold water on him: "The amount of red bricks and cement needed to build a greenhouse is not small, and if the entire Qin Kingdom builds a greenhouse outside the land, it may take many years." ”

"And the greenhouse needs to burn firewood, if the entire Qin country uses firewood to heat the greenhouse, where to find firewood. The large loss of trees in the mountains may also lead to new disasters. Maybe before the greenhouses were built, we had already thought of a better way to increase food production! ”

Yao Xing couldn't think of the scene of the entire Great Qin, and even the whole world later, when he was sober and learned about the scene of the greenhouse farming when he was studying history in later generations.

Zhao Zheng nodded thoughtfully, and did not refute what Yao Xing said.

"The high beds and recliners made by Su Han have been circulated among the nobles before, and they are highly respected, and he has some talent!"
