When polishing stones, Yun Yao made a stone mill by the way, which must be the first stone mill in this era, without any metal processing, all by hand.

With a stone mill, you can process soybeans, you can make soy milk, tofu, tofu skin, ......

Although it is only a small hand-pushed stone mill, it is a great step forward in the gastronomic era.

"What is this?" While Yun Yao was grinding the gym equipment, Ji She found that she was still grinding something else, a round and flat thing.

Finally grinded, but Ji She couldn't understand it, he didn't know what it was to pile two rounded stones together, and he didn't know how Yun Yao thought about it, so he tried his best to pierce a hole in the stone, and he saw Yun Yao grinding hard, and he didn't know what she was thinking about.

It's really laborious, Yun Yao wanted to give up several times, but when she thought that if there was no stone grinding, soybeans would not be food, as a traverser who likes to eat tofu, how could she bear to let soybeans be dusted? So in the end, with perseverance, it can be regarded as creating a primitive stone mill, but it is not easy to use at all.

Faced with the teacher's question, Yun Yao made a few movements, holding the handle and grinding, and there was a piercing 'whirring' sound between the two stone slabs.

"I see, this is training arm strength, let the stone rotate in place, and the arm can continue to get a telescopic exercise, strange thing!" Ji She looked at Yun Yao's grinding action, thinking that this was Yun Yao's own invention of exercising his arms, and exclaimed that it was magical.

Yun Yao suddenly felt that this unsmiling teacher was also quite humorous, and there was a sense of loneliness in his heart, obviously it was an artifact that changed the status of soybeans in the food industry, but it was used as exercise equipment, but Yun Yao couldn't say anything. After all, the problem of seasoning has not been solved, so what if there is only a stone mill? One man no man.

"That's right, that's what you're used to exercise your arms."

Ji She couldn't hold it back, tried it herself, and sure enough, when her arm was grinding, she was exercised: "Good thing, really good thing, I don't know what this thing is called?" ”

"It's called a stone mill." Yun Yao secretly said to Shi Mo in his heart, I wronged you to make exercise equipment, and in the future, I will definitely make the most delicious tofu and tofu skin in the world with seasonings in the future.

"Simple and straightforward." Ji She wants to give herself a set of stone grinding, even at home you can exercise your arms at any time, which is really a good thing: "I used to only know that straight pushing or pulling can be exercised, but I didn't expect the circle to be so useful, the stone mill just keeps spinning in place, but it has a miraculous effect on exercise." The more he looked at it, the more he liked it, and then he fell into contemplation, apparently because he gained a lot from the mystery of bending and straightening.

Ji She was clockwise for a while, counterclockwise for a while, and suddenly thought of something: "I have to build another one, and it is best for the two to cooperate together." ”

"Why?"

Ji She demonstrated the forward and reversed: "If there are two stone mills, both hands are exercised at the same time, one positive and one negative, one forward and one reverse, not only can both hands be exercised at the same time, but also can be used for two purposes, and the positive and negative are endless." ”

Yun Yao was stunned, thinking that he really couldn't underestimate the wisdom of the ancients, although they had little knowledge, it didn't mean that they were stupid, the teacher's thinking was very agile, no wonder he was a master who could cultivate to the realm of four radiants, and when he saw the stone mill for the first time, he thought of how to use the stone mill to train himself to improve his level.

"Then grind again." Yun Yao said.

Ji She nodded: "I really have to continue grinding." ”

When the second stone mill was manufactured, Yun Yao had a new training, two-handed grinding and training the coordination of the two hands.

Now the twenty-stone bow has no feeling for Yun Yao, and it can be easily filled, but she still hasn't understood how to release the white arrow without relying on the power of the bow.

Sometimes standing still, it takes a long time to shoot an arrow, just to figure out how to strengthen the penetration of the arrow. Recalling the teacher's demonstration, it looks like shooting an arrow very ordinarily, but why is the teacher's arrow so powerful? Far beyond the strength of the bow.

Yun Yao has always believed that the power of arrows is determined by the bow and arrows, as for the shooter to be responsible for the accuracy, it is impossible for the shooter to determine the power of the arrow. But the teacher's demonstration overturned Yun Yao's idea and made archery directly enter the realm of metaphysics.

After a long period of tempering, as well as taking the turtle shell three times, although her appearance has not changed much, Yun Yao knows that her strength is already fiercer than that of the tiger and leopard, and it can be said that without a bow and arrow, she can play better. She has such strength, but she can't transfer her strength to the bow and arrow, but she is tied up, and she can't say that she is disobedient.

But Ji She also told Yun Yao that five shots have existed since ancient times, and every shooter can do it, if you can't do it, you don't have comprehension, and Bai Ya can be said to be the easiest of the five shots.

Of course, Ji She didn't tell Yun Yao, although Wujian has been there since ancient times, and everyone can learn, but there are very few who can really learn, Wujian has extremely high requirements for understanding, and many shooters have not been able to master the first shot in their lives. In order not to discourage Yun Yao's enthusiasm, Ji She only said half of what he said, he had high expectations for Yun Yao, and even hoped that she could master all the five shots and become a peerless shooter.

Seeing that Yun Yao was always in a daze and distressed, Ji She also knew that kind of taste of not being able to get started, but this kind of thing the master really can't teach, only the disciples can comprehend it themselves, only by mastering the divine will, can they transcend the strength of the bow and the advantage of the arrow, and can pour all the spirit of the archer into the arrow and use the white arrow.

"She, it's okay for Yun Yao to be in a daze all the time, is there really no way to help her?" Ji Jiang saw that Yun Yao was so distressed, and felt very sorry for this little girl who was only twelve years old, and they adults should help.

Ji She shook his head: "Back then, General Huang taught us five shots, and I didn't know how to do it, and in the end, if it wasn't for the coincidence of using white arrows, I'm afraid that I won't be able to get started with five shots for the rest of my life." With General Huang's cleverness, I can't help us get started, I'm just a personal guard, how can I help Zhu Nu? All I could do was arrange for her to train and wait patiently for the day when she would be able to use the White Arrow. You don't have to worry too much, it took me five years to use the white arrow for the first time, even if Zhu Nu Tianzong is only three months now, for archery, she is just a novice, it is normal to be distressed, which novice is not distressed. ”

Hearing what her husband said, Ji Jiang had nothing to say, but she thought to herself that she could help Yun Yao in other places: "She, why don't you go to that Huang Xiaohu, doesn't he have the ability, you go to him and get more salt." Now that the weather is getting hotter and hotter, Zhu Nu is working hard and sweating, if she doesn't eat more salt, how can she keep exercising? ”

Hearing the name Huang Xiaohu, Ji She frowned: "What are you mentioning him for?" ”

"Didn't he always want to be your subordinate, what's wrong with you letting him find salt? I know you look down on him, but you also have to think about Zhu Nu. Ji Jiang is not wrong, the weather will indeed become hotter and hotter in the future, and Yun Yao is practicing hard every day, if she doesn't eat salt, she will definitely not be able to hold on.

It's just that Ji She obviously doesn't like the guy named Huang Xiaohu.
