The principle of the keel water wheel is clear at once. Qi Geng, who understands this, scratches his head and looks at Xiong Jing with a complicated look. Perhaps he thinks Xiong Jing is too incredible, but the incredible is still behind.

At Xiong Jing's instructions, a red tree that had just been cut down was brought in. The two men used an axe and saw to cut a small piece from it. The two were not carpenters, and their actions were so unfamiliar that they looked at Lun Er. Qi Geng felt uncomfortable all over, but the master did not give them instructions. They could only look sore teeth, wink and look at them, and wait until the wood chips were removed, and everything returned to normal.

Xiong Jing didn't seem to see the discomfort between the two because he wanted to popularize science.

"There are all trees in nature, and they have their own nature." He coughed before he started speaking. "The nature of all trees is easy to understand, but the nature of wood is not easy to understand. Twisted, cracked, cross-cut, and sunken are all stubborn diseases of wood. I think these stubborn diseases are related to water."

It has something to do with water? Both of them understand the meaning of Xiong Jing's words, but they don't understand the reason. "Please give me advice," Qi Geng bowed.

"All living things contain water, so does wood." At this time, the vertical men placed the removed wood pieces on the balance weighing gold, recorded the weight, and put them into a copper box, and burned it under the box to fire. "The water content of wood is A, and the weight without water is B. The difference between A and B is water weight. The water weight ratio of wood weight is water content. Different moisture contents are different, so wood needs to be dried and made..."

They are all old carpenters. When Xiong Jing said this, they nodded at the same time. They understood this principle very early, but this scientific explanation was the first time. Xiong Jing continued: "It is extremely dangerous to walk on the sea, and the moisture content of each department must be stipulated. In the future, the moisture content of the wood must be indicated in the shipyard craft manual..."

I couldn't understand it, but fortunately Xiong Jing then explained: "The so-called craftsmanship manual is the steps of how craftsmen work, cutting first, sawing first or scattering first, length, short, width, and thin, everything is customized. In short, it means using the least strength, the least time, and the least wood to meet the design requirements. This is the purpose of the craftsmanship manual. Do you understand?"

"Yes." The two leaned over and bowed.

"The wood is still drying. After four hours, you can bring other people in to see what the moisture content is." All the explanations were explained, but the moisture content must establish an impression in front of everyone.

"Does Your Highness return to the school?" It was dark four hours later, and the school was in the last lunar calendar. Today, Xiong Jing did not go to the library.

"Back." Looking around this place of hope again, Xiong Jing nodded.

The shipyard is north of Zijin Mountain, Shouying is southwest of Zijin Mountain, and the Academy is south of Shouying. If you take a bus, you have to go around a lot. Fortunately, the Huai River enters Shouying, and the water comes out of Shouying, which is Shaopi. This is a water conservancy project that is more than 300 years earlier than Dujiangyan, and Shaopi connects Lantai. It only took Xiong Jing from the Academy in the morning.

After boarding the boat, after entering the water gate, Xiong Jing, who had left the school privately, had to hide in the boat cabin and look at the shore through the wooden window. Shouying is the capital of Chu. Although it is not as prosperous as the old Ying, the population is 400,000 to 500,000. From the Huai River, I saw boats like forests, and countless boats were swaying on the shore, close to both sides of the moat of Shuimen. There were many pedestrians, and shops and houses were connected to buildings.

For the ancients, Shouying was a big city, and for Xiongjing, it was just a small county town, a great prefecture-level city, and there was nothing good to watch. He was concerned about the boats along the road now. Of course, there was no sail. He knew this in later generations. Although some people used the word "sail" in the pre-Qin period to make an article, and the meaning of "sail" was "general", this is the characteristic of sails, which shows that ships in the pre-Qin period already had sails, but this explanation was from the Eastern Han Dynasty.

Nowadays, boats, boats, and boats, according to Xiong Jing's observation, there are no sails, and sailing depends entirely on boat oars. Not only does there be no sails, but there are no rudders. There are no oars yet. This is what Xiong Jing did not expect. He thought there were oars in this era, but there were no oars. The efficiency of oars is very low. It is good to go down the river along the water, but if you go up against the current, the oars will probably be exhausted. Some places with fast flow may not be able to get up, so you can only rely on the shore to pull the fiber.

Looking at the oncoming boats, Xiong Jing felt more and more superior. He could not imagine how everyone would think of this kind of ship that was traveling by the wind and turning to a rudder after the first sailboat was built.

Xiong Jing, on the boat, proudly felt a sense of superiority. In the bustling market of Yingdu, there were endless shouts. A depressed scholar with a broken dress and a rat-bearded mouth also felt a lot of superiority when he saw things full of the market.

"This thing is edible." He grabbed a large piece of vinegar meat in his hand, and then quickly put it in his arms. The vinegar seller was greeting other guests, but when he turned around, he found that a piece of vinegar meat was missing.

"This clothes can be worn." He was holding a heavy piece of vinegar meat in his arms, and saw a shop buying clothes. Looking at the torn and exposed flesh of his clothes, the mouse had to squeeze to the side of the shop without hesitation, and grabbed a piece of clothing and removed it. This time, he was not so lucky. The clothes were tied with ropes, dragging one piece of clothing. The owner of the shop immediately shouted: "Someone steals! Someone steals!!"

The stolen clothes were also stuffed into his arms, and he didn't notice a large string of clothes hanging behind him. Following the crowd, the mouse had to continue walking. When he passed by a shop, he saw that it was a flint seller. He murmured again, "This tool is available," and then grabbed a piece of flint in his hand.

"Where is the thief going?!" A roar was heard behind him, and the soap official wearing a crown and a sword lifted the rat moustache. He followed him along the dragged clothes.

"Catch the market and steal it, catch the market and steal it..." The pedestrians couldn't help but stop and watch. The shop owners on both sides stood at a high place - Shouying's market is prosperous, but there are also many steals in the market. Today, I finally caught one, and I really applauded.

"Why steal?" The breathless city official came up, not caring about sweating. Seeing that everyone was watching, he immediately questioned.

"Ah..." The mouse trembled when so many people watched. At this time, the soap official was already sucking out the things in his arms, such as vinegar meat, clothes, flint, dried fruit, and even a hairpin used by a woman.

"Why steal?" The evidence and physical evidence were present, and the city officials became more and more confident, and their voices became louder.

"I..." The mouse had to look at the things that were taken out of his arms and finally recovered his mind. "When the fire of sharpness was burning, his eyes were dizzy and the things he saw were like I had, and I didn't know it was stealing."

"Haha..." The answer aroused laughter. 'Everything I saw was like I had', and this was also a reason for stealing things.

"I am a village teacher, no student has started this spring. The mother and child at home have been hungry for ten months, so they have to steal." Perhaps because they were stimulated by laughter, the mouse must subconsciously reveal his identity. Everyone laughed and then laughed again.

"Since I am a village teacher, I should understand the law of stealing in the Great Chu." The city officials looked at the mouse and saw a few literati and nerd. Although they felt a little sorry for the village teacher, he finally said: "Everything will be defeated by the defeat of the Si Dynasty and taken away!"

"Let's go!" Surprisingly, two strong men flashed among the onlookers, both of them were black gauze, carrying long swords, and the beards that spoke like iron needles, with dark skin. When they saw this outfit, the shop owner who was looking up at the height quickly shrank his head, scolded and kicked the servants quickly closed the stall. Some of the onlookers also began to retreat, and the narrow space that was originally surrounded was suddenly several times larger.

"Stealing is against the law." Looking at the two, the city officials shouted, but their hands were pressed on the hilt of the sword, just like the two soap officials behind them. "What do you mean by you? This is the capital of Chu, and there are 100,000 soldiers and horses in the city, and you... "

"The rural master has a hard time and cannot make a living. He is not willing to steal. We just want to pay coins for him." A piece of stuff was taken out, and it was a silver cake. The older man in black threw it directly into the arms of the city officials, but the city officials did not dare to take it.

"This person steals, and the stolen people are both captured. According to the law, I need to ask the company to lose, how can I release it privately?" The silver cake fell on the ground, but it is common for people to catch the steal, and it is impossible to release the person even if I want to release him. "I advise you to wait..."

With a few "swish" sounds, three copper swords were unsheathed, but the tip of the sword was not yet aimed at the visitor. A figure flashed in front of him. The man in black had already bullied him, and he stabbed him with a punch, kick and a sword. All the municipal officials were lying on the ground. However, some good people had already ran to report to the officials. As soon as the municipal officials fell to the ground, they heard the sound of gongs and a group of military flags arrived.

"Go away!" The two rangers who drew their swords to help saw that the matter was getting worse, and they set up a confused village teacher to run towards crowded places without saying that they could not tell. They overturned countless shops along the way. The market was in chaos for a while, and the grand occasion of the day of chasing rabbits was repeated.

"Your Highness, please have tea." On Qinghan's boat, Ge came in with tea from outside the cabin. Xiong Jing didn't like pepper and plum slurry, so he only drank some jujube. However, since he found tea trees in the palace garden, he ordered people to pick tea leaves and stir-fry them, and then drink tea every day.

The tea was placed on the table. Before Xiong Jing could pick up the tea cup, the tail of the boat sank and the whole boat swayed. Ge immediately stood up and thought it had collided with another boat. Unexpectedly, when the curtain was raised behind him, several people rushed in, so fast that it was at a loss.

"Who?" Ge Li shouted loudly, and the guard Yu and Qin approached the boat's head and stabbed several swords at the visitor, but they were almost avoided by him. Xiong Jing was also stunned and was about to leave the city. Why did several sword-holding gangsters run in?

"Either rich or noble, you can kill them all!" Entering was the black-clothed ranger who was just helping others in the market. During the fight, the black-faced one looked around the boat. Seeing the luxurious decoration, Ge and Yu were wearing brocade clothes again, he immediately had a murderous intention.

"No, the heroes will not deceive women and children." The old-fashioned elderly person was almost stabbed by Yu Yishang until he flashed to Xiong Jing's side.
