Yao Ran shook his head before noticing that before he knew it, several palanquin drivers had carried themselves to the river, and his three apprentices were naked on the edge of this shallow, two of them were holding a few pieces of wood in their hands, and one was half-squatting in the water as if looking for something else. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoYao Huo is trying to climb on the wood. But because the wood was too short, it was pressed into the river as soon as it was pressed, and the person naturally turned into the water.

Yao Ran nodded, and couldn't help but laugh. They discovered buoyancy in the water, but they didn't fully understand how it was used. Of course, it's okay to take a boat with wood. But it has to be big enough.

The waterwheel that Yao Ran wants to do this time is to use the fluidity of water to push the waterwheel to the blower, so that the blower can work stably and quickly. Thus saving manpower. There are many more things in the future that can use the same principle. A windmill that uses wind power. Rice noodles can be grinded. A large number of waterwheels can be made for hammering pig iron, resulting in medium carbon steel.

After the four palanquin men waded across the river, Yao Ran was put down at Yao Ran's order. When the three apprentices saw Yao Ran coming back, they hurriedly climbed ashore from the water. After shaking off the water on his body, he got dressed and ran in front of Yao Ran. Yao Ran arranged for Lang Yan to run back to Yao Village with two sedan chair drivers, and the three of them ran over as soon as they left Yao Huo, Hua Tuo and Xiaoping.

After saluting, the wet hair of the three people was still dripping water on the ground, Yao Ran was very satisfied with the appearance of the three apprentices who had just seriously thought about and dared to practice by the river, but he was not so satisfied with their research results.

There is no way to develop the waterwheel nearly a thousand years ago, tens of thousands of years of primitive people just began to contact the use of tools, it was Yao Ran who started the use of their composite tools. Now that we're about to get to the beginning of the Iron Age, we can't pursue too much.

Yao Ran was kind and asked, "How can the water be cold or not?" ”

Yao Huo was the first to say: "The water is not very cold. Teacher, we found that water makes light things float, but sediment things go down. It was also discovered that water could carry light things down the river. So with this power, you can help us carry wood from the riverside village. ”

Yao Ran's eyes lit up, yes, this kid is smart, he didn't expect to use the river to transport timber to make this kid think, after all, Yao Ran is a modern person, it is impossible to apply everything he has seen before, and the application of various knowledge that he has not seen, although he has a retinal system such a retinal system to assist himself, but the application of things still depends on improvisation and adaptation to local conditions.

Yao Ran is very pleased, this is a good sign, if he can cultivate dozens or hundreds of Yao Huo, Hua Tuo, and people like Xiaoping, after his own systematic training and explanation of them, and then there is a practical application, will it be far from the scientific and technological blowout civilization leap? Hope lies ahead.

"Yes, very good, you really studied and observed." Yao Ran patted the shoulders of the two students and said.

Yao Huo, Xiaoping and Hua Tuo, who were praised, all showed different expressions, Yao Huo smiled a little embarrassedly and grabbed his hair with his left hand, while Hua Tuo tilted his head and looked at Yao Ran with some pride. It was like waiting for Yao Ran to praise him alone.

Yao Ran saw it and laughed in his heart, this kid. But Yao Ran didn't skimp on his own language and said: "Hua Tuo is also very good, let you come over and participate in the study together, in order to broaden your horizons and make your head more flexible." In this way, we can better learn medical skills and treat more people. What's more, your energy alone is limited, and you can't treat thousands of people. Therefore, you also need to train more medical talents and health superintendents to help our people and let them live a long life, okay? ”

Hua Tuo listened to Yao Ran's words, as if he wanted to take a reassuring pill, nodded solemnly, and stared into the distance. This chicken soup is poured into a primitive medical genius, no less than talking to a 5-year-old child who has just finished watching a Marvel hero movie, and the heavy responsibility of saving the earth in the future. It's on your shoulders, and there's something similar.

But Hua Tuo still eats this set, Yao Ran's grasp of the humanity of the people around him has reached the realm of perfection and ease.

Xiaoping is very similar to Yao Huo's expression, and there is no special movement. But he was very proud, but he was a little disdainful of Hua Tuo, a later person.

Yao Ran continued, "The method of using water conservancy to transport timber is very good to save time and effort, remember to inform Yao Shi and the others to let them stay, and the transport team led by Wei Mu will be everyone." Yao Huo went to teach them how to use the river to transport timber, of course, to be thoughtful, what to do if they encounter a shoal, how many pieces of timber are bundled together each time to transport can maximize the efficiency and safety of transportation? These are all questions that need to be considered before being done. ”

"But what I'm going to do today is not how to use the river water to transport the wood, but today we're going to use water to push our blowers to help us burn the flame of the ironmaking blast furnace higher and stronger." Yao Ran continued.

"You three come with me." The master and apprentice walked to the river, Yao Ran took out a small leather bag in his bag, poured out a small section of carbon black inside, and began to write and draw on a relatively flat large bluestone on a large bluestone that was hot in the sun.

Yao Ran first drew a circle, and then drew some horizontal lines at equal distances on the circle, saying, "The power we want to use this time is the power of the water flow, which is slightly similar to transporting wood. The purpose is not the same. ”

"We were going to make a device that could be hit by the current all the time without moving its position." Yao Ran pointed to the simple circle he had drawn. Said.

"So we first have to build a circular frame, and then install some wooden planks at equal distances on top of the frame, so that these planks can be impacted by the water flow and then drive this large frame to rotate, so as to drive the impeller in the blower we want to drive to rotate at the same time. In order to achieve the purpose of blowing the wind into the entire iron-making blast furnace to heat up the flame. Do you understand that? ”

Three apprentices, Yao Huo touched his chin, Xiaoping's imitation ability was strong, learning Yao Ran's movements and touching his temples, just like Yao Ran's movements when he used the retinal system. Hua Tuo was a little wooden, staring at the big stone, and his gaze obviously did not fall on the position where the simple sketch was drawn.

But the first to speak was really Hua Tuo, who had the dream of saving lives and helping the wounded, a physics transfer student. (To be continued.) )
