The princess sent everyone away, except for Sun Qing, and of course Biao Wanzi and Sun Boji did not agree.

But they hesitated for a long time, and finally didn't dare to say anything, but left Anche silently to carry out the order given by Yin Xi.

Yin Ji sighed in her heart, but she still got down to business first: "I see that the food that is delivered to me on weekdays is different from ordinary food, why is this?" ”

Sun Qing was puzzled at first, grains are the size of grains, full and shriveled, and have a fine taste, which one did the princess say? But he quickly turned the corner: "The princess means the outer shell of the grain?" The shell is rough and hard to swallow, and the food delivered to you with the dignity of a princess is naturally licked. ”

This is also one thing that Yin Cheng only discovered recently.

Because the grain brought to her was always husked, the millet and wheat were ground to pieces, and the yellow rice porridge was boiled very thick. So she never thought that there was no stone mill yet!

It wasn't until she left the Zhaowang Palace this time that she had been observing the entire team with her strength, as well as the environment along the way, that she found that the cooking in the team was to pour a handful of wheat or beans directly into the kettle and cook it in the shell.

Yin Ji asked the palace people in surprise, only to know that there was only one way to hull the grain at this time - using manpower.

A huge stone mortar filled with millet is then required to be smashed with a mallet to smash the rice bran off. A handful of millet may have to be smashed hundreds of times before it can be completely shelled.

You can imagine how much effort it takes and how hard it is.

Even in the Zhao Palace, only the superiors and the servants around them could eat meals made of husked grains - the former was because of their noble status, and the latter was afraid of villains.

That's why Yin Ji didn't know anything about it.

Everyone around her has benefited from her.

In order to provide for the daily needs of these people, there are thousands of criminal slaves in the court who are licking rice day and night, they have no clothes to cover their bodies, they have no time to rest, and if they are lazy, they will be whipped and may die at any time.

Yin Ji also asked the palace people who accompanied her to know that in the Zhaowang Palace, Chung Mi is a job that only sin slaves do.

This is because, in order to prevent the hair from falling into the grain and being eaten by the nobles, the person who eats the rice must shave all the hair. If it's a man, shave off your beard as well. And in this day and age, shaving hair is a great humiliation, just like the so-called parents of the body, shaving hair is like shaving the head, and only sinners will be treated as such.

Because of this, after listening to Sun Qing explain how difficult it was to make rice and how many slaves were needed, and only the nobles of the palace could afford to use it, Yin Cheng "suddenly realized" and said, "Why do you want to use people to do it?" Those slaves are rough and stupid, no wonder they can't do things well. Since stones can crush grain, why can't you use stones to grind grains, and maybe you can grind finer flour and make something more delicious! ”

Sun Qing said whimsically to the little princess: "Princess, the big stone that can grind grain must be used by a strong man, this is a tyrannical thing!" ”

With this kind of strength, isn't it good to go to the battlefield and fight? Why be the lowest slave of rice?

Yin Ji disagreed: "A piece of wood can still pick up two buckets of heavy objects, why do you have to use it?" ”

Sun Qing was stunned for a moment, then seemed to think of something, and immediately said, "What the princess said is extremely true. ”

He felt that the princess was right, that a light piece of wood and a bamboo pole could lift items far greater than their own weight, so why couldn't a stone be lifted? If you can find a way to make the stone turn and grind, the grain will be hulled!

Sun Qing knew very well that the relationship between the princess and the king was definitely not as cold as the rumors. The king took great pains to keep the princess's secret, and sent the princess to Minjun, there must be something important!

What does this mean!

The princess is the closest and most trusted person to the king!

If the princess is willing to say a good word for him in front of the king, it is better than a thousand words for others!

Although Sun Qing didn't know what the king wanted the princess to do, he knew very well that the princess's trip was because of the letter from the Taishou of Minjun, so when she arrived in Minjun, everything would be clear. As long as the slope is crossed, the sky is high and the earth is far away, and the princess may not need to continue to sit in the car. And at that time, there were many smart people who could discover the wonders of the princess and figure out the key!

Sun Qing knew that the princess was only a little interested in him, but she didn't use him, if he didn't take advantage of this point in time to seize the opportunity, but was forgotten by the princess. When the princess was surrounded by smart people, he was a lowly official, and he didn't know when he would see the princess again, let alone when he would come out.

But if he can turn the princess's idea into reality, even if it is just the princess's casual joke, if it comes true in a blink of an eye, the princess will be surprised, and she will think that he is available, and summon him a few more times. And he has seen the princess more times, so he will naturally find a way to get the princess to introduce him to the king!

So he had to take every opportunity!

Sun Qing's own family business is rich, of course he understands, if he can really make a farm tool for crushing grain, where can ordinary people afford it? Of course, it is used by the royal family and ministers!

Only aristocrats who don't worry about food and clothing will pursue the fine taste of food, right?

In this way, which big man would not know his name Sun Qing?

Seeing that Sun Qing couldn't wait, Yin Cheng casually asked a few more words, then sent him away, and then sat alone on the car, looking silently at the "window".

She didn't know exactly what the stone mill looked like, so she could only describe it roughly.

Judging by her two contacts with Sun Qing, although this person is a young genius, his heart for fame and fortune is also very strong. As long as he can get ahead, he doesn't care whether he is a minister or a fortunate minister, so Yin Ji deliberately acted that he was just curious about Sun Qing, but he didn't have any more interest.

In order to win her attention, Sun Qing will definitely study stone mills.

Yin Ji just needs to pay attention to this process and give him some hints.

Of course, Yin Cheng knew that Sun Qing must have thought that she was going to make a stone mill in order to enjoy the food. But she didn't know that she had been thinking for many days about how to use the power of "witches" to increase food production.

She did not dare to infuse the seed directly with her strength, for fear of causing species to mutate and bring unknowable risks. So she made up her mind that after Minjun, she had to get a test field and study it carefully.

This is something that Yin Ji has decided to do and intends to solve in two years, so she has to think about the follow-up.

Once the grain output increases, it is imperative to dehull and refine the grain.

After all, the hard shell on the outside of the grain can't even be digested by cattle and horses, let alone people? Eat this stuff every day, and if you don't die, your fortune will be great.

Especially children, with delicate stomachs, can survive by eating such coarse grain and rice for meals, purely by relying on hard life.

Thinking of this, Yin Ji sighed silently.

Set a small goal first, and within five years, let the people of Zhaoguo eat rice and white noodles!
