The principle of the keel waterwheel is clear as soon as it is explained, Qi Geng, who understands this principle, scratches his ears and cheeks a little, and looks at Xiong Jing with admiration and admiration with complexity, maybe he thinks Xiong Jing is too incredible, but the incredible is still to come.

At Xiong Jing's signal, a red solid tree that had just been cut down was brought in, and two shafters used axes and saws to cut off a small piece of it. The two of them are not carpenters, and the awkwardness of their movements makes Wheel Er and Qi Geng uncomfortable, but the master did not order, they can only look at it with sore teeth and squeezing their eyebrows, and when the wood chips are removed, everything will return to normal.

Xiong Jing didn't seem to see the discomfort of the two, because he wanted to popularize an extremely important matter.

"Born with all kinds of trees, each with its own nature." He coughed before he began to speak. "The nature of ten thousand trees is easy to understand, but the nature of wood is not easy to understand. Twisting, cracking, traverse, and depression are all stubborn diseases of wood, and I think their stubborn diseases are related to water. ”

Water-related? The meaning of Xiong Jing's words is understood by the two, but the two of them don't understand the reason. "Childe, please." Qi Geng said.

"Every living thing contains water, and so does wood." At this time, the shafters put the removed pieces of wood on the scales weighing gold, wrote down the weight, and put them into a copper box, under which a fire was burned. "The weight of the wood with water is A, and the weight without water is B. The difference between A and B is the weight of water. The water-to-weight ratio of wood weight is the moisture content. The moisture content is different for different wood properties, so the wood needs to be air-dried for ......"

They are all old carpenters, and the two of them nodded in unison when Xiong Jing said this, they have understood this truth for a long time, but it is the first time they have heard such a scientific explanation. Xiong Jing continued: "The ship is extremely dangerous when it travels on the sea, and there must be regulations on the moisture content of each department. In the future, the moisture content of the wood must be indicated in the shipyard process manual......"

I didn't understand, but fortunately, Xiong Jing then explained: "The so-called craft manual, that is, the steps of how the craftsman works, first cut or sawed or planed first, long and short geometry, wide and thin geometry, everything is customized." In short, it is to achieve the requirements of the design with the least effort, the least time, and the least amount of wood, which is the purpose of the craft manual. Got it? ”

"Yes." The two leaned over and bowed.

"The sample wood is still drying, and in four hours you bring the others in to see what the moisture content is." The explanation is all over, but the moisture content must establish an impression in front of everyone.

"Is Your Highness going back to the Academy?" Four hours later, it was already dark, and the school palace was a ten-month holiday, and Xiong Jing did not go to the library today.

"Back." Looking around at the land of hope again, Xiong Jing nodded.

The shipyard is in the north of the Purple Mountain, Shouying is in the southwest of the Purple Mountain, and the school palace is in the south of Shouying. If you take a car, then you have to go around a big circle, fortunately, Huaishui enters Shouying, and the water comes out of Shouying, that is, Shaobi - this is a water conservancy project more than 300 years earlier than Dujiangyan, Shaobi Tonglantai. It only took two hours for Xiong Jing to come from the school palace in the morning.

After boarding the boat, after the boat entered the water gate, Xiong Jing, who left the school palace without permission, had to hide in the cabin and look at the shore through the wooden window. Shouying is the capital of Chu State, although it is not as prosperous as Jiuying, and the population is also 400,000 or 500,000. From the beginning of Huaishui, you can see that the boats are like forests, countless boats are moored on the shore, and on both sides of the moat near the water gate, pedestrians are weaving, and the shops and houses are even more connected.

For the ancients, Shouying was a big city, and for Xiongjing, it was just a small county, a great prefecture-level city, and there was really nothing to see about it. He now cares about the boats along the road. Sail naturally did not have, this point he later generations knew, although some people made a fuss about the word "sail" in the pre-Qin period, saying that "sail" means "pan general", which is the characteristics of sails, indicating that the ships in the pre-Qin period already had sails, but this explanation is the Eastern Han Dynasty.

Today's boats, boats, and boats, according to Xiongjing's observation, all have no sails, and navigation depends on oars. Not only is there no sail, but there is also no rudder, and the turn is all by a tail rotor. And, there is no oar. This is what Xiong Jing didn't expect, he thought that there was already a lug in this era, but there was no. The efficiency of the oars is very low. It's good to go down the river on the river, but if you go upstream, the oarsmen will probably be tired to death. Some places with fast flow speed may not be able to go up, so you can only rely on the shore to pull the fiber.

Looking at the oncoming boats, Xiong Jing felt more and more a sense of superiority, and he couldn't imagine what everyone would think of this kind of ship that took advantage of the wind and turned to the rudder after the first sailboat was built.

The bear thorn on the top of the boat proudly gave birth to some sense of superiority, in the bustling market of Yingdu, shoulder to shoulder, shouting constantly, a certain rat with tattered clothes must see the things in the market, and also gave birth to a lot of superiority.

"It's edible." A large piece of meat was grabbed in his hand, and then quickly put it into his arms. The seller was greeting other customers, and when he turned around, he realized that a piece of the meat was missing.

"You can wear this garment." With a heavy piece of meat in his arms, he saw a shop buying clothes. Seeing that his clothes were torn and exposed, the rat beard did not hesitate, and squeezed to the side of the clothing shop with all his might, grabbed a piece of clothing, and withdrew. This time it was not so lucky, the clothes were all tied with ropes, one by one, and the owner of the shop immediately shouted: "Someone has stolen!" Someone steals!! ”

The stolen clothes were also stuffed in his arms, and he did not notice that there was a large string of clothes hanging behind him, and the rat continued to move forward with the flow of people, and when he passed a shop and saw that it was a flint seller, he muttered again, "This instrument can also be used", and then grabbed a piece of flint in his hand.

"Where are the thieves?!" There was a loud roar behind him, and the soapman with the crown and sword lifted the rat's whiskers, and he followed him along the clothes he was dragging.

"Catch the city and steal, catch the city and steal the ......" pedestrians couldn't help but stop and watch, the shop owners on both sides stood on the high place - Shouying market is prosperous, but there are a lot of thieves in the market, today it is hard to catch one, it is really a clapp.

"Why steal?" The panting city official came up, didn't care to wipe his sweat, and when he saw that everyone was watching, he immediately questioned.

"Ah......" was watched by so many people, and the rat was trembling, and at this time the soap man was already picking out the things in his arms. Pickled meat, clothes, flint, preserved fruits, and even a hairpin for a woman.

"Why steal?" The human and material evidence was there, and the city officials became more and more reasonable, and their voices couldn't help but be a little louder.

"I'm ......" Ratbeard looked at the things that had been pulled out of his arms, and finally regained some senses. When the fire is blazing, my eyes are hot, and everything I see is like what I have, and I don't know whether it is stolen. ”

'Haha......" replied with a burst of laughter. Everything you see is like I have', which is also a reason for stealing.

"There has been no student since this spring. The old mother and child in the family have been hungry for ten months, and they have to steal it. Probably stimulated by laughter, the rat subconsciously revealed his identity. The crowd laughed for a moment, then laughed again.

"Since you are a township teacher, you should know the law of theft in my Dachu." The city official looked at the rat whiskers twice, and he did look like a literati nerd. Although he felt a little sorry for this village teacher, he finally said: "Everything is caused by the defeat of the division." Take! ”

"Wait!" Unexpectedly, two strong men flashed out of the crowd of onlookers, both of whom were black Ge cloth and carried bronze swords. As soon as he saw this outfit, the shop owner who was looking at the height hurriedly shrank his head, scolded and kicked his feet, and asked his subordinates to quickly close the stall. Some well-informed onlookers also began to retreat, and the small space that was originally enclosed suddenly became several times larger.

"To steal is to break the law." Looking at the two of them, the city official said loudly, but his hand was pressed on the hilt of the sword like the two soap officials behind him. "What do you want? This is the capital of Chu, and there are 100,000 soldiers and horses in the city, and you are waiting for ......."

"The village teacher has a hard time, he has no way to make a living, and he doesn't want to steal, so we just want to pay the money on his behalf." A piece of something was taken out, it was a silver cake, and the older man in black threw it directly into the arms of the city official, but the city official did not dare to take it.

"This man steals, and everyone gets the stolen goods. According to the law, if you need to ask the secretary to fail, how can I let it go privately. "When the silver cake falls on the ground, it is common to see that it can be caught and stolen, and even if you want to release someone, it is no longer possible." I advise you to wait ......"

With a few sounds, the three bronze swords were already out of their sheaths, but the tips of the swords were not yet aimed at the comer, and the figure flashed in front of him, and the man in black had already been bullied in front of him, banging and stabbing with fists and feet, and the city officials and soap officials all lay on the ground. As soon as the city officials fell to the ground, they heard the sound of gongs and a line of military flags rushed to the ground.

"Let's go!" Seeing that the matter was getting bigger, the two rangers who drew their swords to help each other ran towards the crowded place without saying that they had set up a confused village teacher, and overturned countless shops along the road, and the market was in chaos for a while, repeating the grand occasion of chasing rabbits.

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

The tea was placed on the table, and before Xiong Jing picked up the teacup, the stern of the boat sank, and the whole boat swayed. Ge immediately got up, thinking that he had collided with another ship, but as soon as the curtain was lifted behind him, several people rushed in, which was so fast that people were at a loss.

"Who?!" Ge Li shouted, and the guards and birds close to the bow of the boat aimed at the comer, and even stabbed a few times, but they were all narrowly avoided. Xiong Jing was also stunned, he was about to leave the city, how could a few sword-wielding gangsters run in.

"If you are not rich or expensive, you can kill them all!" Coming in was the black-clothed ranger who was helping people in the market just now, and during the fight, one person looked around the boat, and saw that the decoration was extravagant, and Ge and Yu were dressed in brocade clothes, and they suddenly became murderous.

"No, chivalrous people don't bully women and children." The elder was almost stabbed by Yu Yi's sword until he flashed to Xiong Jing's side.

The four swords faced each other, and the two replied in a low voice, and the accent was not something that Xiong Jing and the others could understand. Everyone was worried, there was a gong on the shore, and the soldiers who were chasing after him arrived, and Ge Gang, who heard this, wanted to shout, but saw a sword on Xiong Jing's neck.
