Mu Chenyu went to find Shangguan Juan, thinking that he was taking the opportunity to inquire about the Soul Turning Seal in the hand of Jade Yama from Shangguan Juan's middle door, but he was holding a pastry in his hand, and just came over, he saw Shangguan Juan sitting in front of the table.

The girl's posture is gentle, her long hair is scattered on her shoulders like a delicate waterfall, she is very good-looking, and the pink and tender between her fingers can make Mu Chenyu see it clearly at a glance. Shangguan Juan held a charcoal pen in his hand and made changes on the drawings from time to time.

Only then did Mu Chenyu set his eyes on the paper, which was Shangguan Juan's preliminary design for the plow rake.

"Xiao Jiu, you scared me a lot, standing behind me, why didn't you make a sound?" Shangguan Juan was immersed in creation, and suddenly came back to his senses and found that there was a person standing behind him, startled, this Xiao Jiu didn't know when he came in, and he still had pastries in his hand, so he should have been waiting for a long time.

"It just so happens that I'm hungry too, let's eat together, Shangguan Juan put down the pen directly."

This kind of rake can be used as a tool to speed up farming, greatly saving interest, Shangguan Juan borrowed the leverage principle of later generations to be considered satisfied.

"Miss, your drawings are simply incredible, although I knew that you had a lot of ideas, I didn't expect you to have so much wisdom." Mu Chenyu saw the difference between this fence at a glance, the labor-saving part, and it does not need to be operated by two people at the same time, as long as one person can complete it.

"Study hard, your young lady knows more, if you have half the wisdom of your young lady, you will definitely not worry about eating and drinking in the future."

Saying that, Shangguan Juan raised his eyebrows and looked at his drawings with satisfaction.

"I use the principle of lever in this diagram, the longer the lever arm, the smaller the force, so a person can also push, only the work efficiency can be improved, in order to improve the yield of grain, but also reduce the damage to the rice field."

This theory is the first time Mu Chenyu has heard of it, and it is very reasonable, and Shangguan Juan has carefully demonstrated it.

Mu Chenyu felt that Shangguan Juan didn't look like a boudoir lady at all from a long time ago, and had a lot of ideas, but they were all based on his knowledge, and these knowledge were not taught at all in the current school, and Shangguan Juan's understanding of farming was obviously not a realm that an ordinary boudoir lady could achieve.

"And now is the time for farming, if the direct effect is still inappropriate, you can see what else can be improved by this rake?" Mu Chenyu also began to seriously imagine that if the plow and rake can be used in practice, if it can increase the labor rate, then there will be an opportunity to increase the output of grain, and only when there is more grain can the country be rich.

Mu Chenyu, who is the crown prince, knows all of them, and there is a faint expectation in his eyes.

"Yes, the most important thing is to rush time now, but Master Li doesn't know what the situation is? Can it be done quickly? ”

Shangguan Qian sighed, that Master Li's personality has always been tough, and his cooperation with himself is also semi-threatening, if you want him to speed up, I'm afraid it will take a lot of effort.

"Leave it to me if it's okay, I will follow Master Li every day, it's better to have someone to follow than no one, then Master Li is embarrassed to keep dragging it out, right?"

It is a good thing for the country and the people, Mu Chenyu feels that he should take action, even if he is not in the court now, it is a good thing to be able to keep up with such a feat.

"Then it's troublesome for Xiao Jiu to keep up, and this is only the first version, and it still needs to be improved in the later stage, so this time will be quite long."

As soon as Shangguan Juan said this, Mu Chenyu took action the next day.

"So Xiao Jiu went to Master Li early?"

Shangguan Juan looked at Vanilla and Yuejiao funny, I don't know when my own Xiao Jiu was so strong in execution, and according to Vanilla, Master Li was already busy with his own Xiao Jiu.

"Yes, although it is polite, someone has been waiting there, and Master Li is not easy to catch up with in Houfu."

Vanilla recounted today's events funny, thinking that it would be difficult to make Master Li anxious, originally Shangguan Juan was angry with the master there, but now people have to let go of how much anger they have to help themselves.

"Let's go and see what happened."

Shangguan Wan slowly shook towards Master Li's courtyard, because Master Li clearly asked that he was unwilling to be in the company of others, so he was placed in a remote place.

In the distance, the three of them heard the sound of wood cutting.

"You kid, can you get out of the way!" Master Li's cursing made Shangguan Juan startled, but Xiao Jiu didn't flinch at all.

"Master Li, I hope you don't waste your time, this thing is made for proper use."

"I know! How I didn't know! ”

Shangguan Juan looked at it funny, but felt that it was quite interesting to stay here.

"Miss..."Mu Chenyu looked back and saw Shangguan Wan's smiling face, and carefully checked himself, there was nothing wrong with it, but there were sawdust on his head.

"Let's take a look at what's going on..."

"Whatever are you going to do one or two, you are all bothering me!" Master Li didn't expect that the people in Ninghou Mansion were so annoying, but he couldn't let go of what he had promised.

"I'm also worried about the progress, and if there is anything inappropriate, we can also hurry up and improve." Shangguan Juan asked Vanilla to pull the chair, which meant a tug-of-war.

"You are responsible for taking care of my lady, and I will leave the rest to me, although you are advanced, but in my hands, it is easy!"

Hearing this rhetoric, Shangguan Juan also had a score in his heart, this Master Li is not a person who is willing to say big things casually, it can be seen that he is also nine out of ten.

With so many people accompanied, it didn't take long for Master Li to make the first version.

The finished product is like an eight points from Shangguan Juan's imagination.

"I didn't expect you, the daughter, to have such thoughts." At the beginning, this Shangguan Juan came to find him, and the reason why he was reluctant was because he was afraid of something extravagant, but he didn't expect that it would be for the good of the people, and he could do it to this point.

"There is also the processing of materials and the simplification of processes, and we can only know if we are doing it right when we use it on the ground."
