With 30,000 stone grain and grass, Li Danghu and Wei Qing were exchanged for a Sima and Qidu, and the two happily took people to the barracks, and the Changshi Mansion instantly became deserted. Hawking was very unhappy, because Li Danghu took Li Kang away, leaving only him and Shi Bao. followed Su Ren all day long, shouting that he wanted to go to the barracks, even if he was a captain.

Su Ren kicked Hawking in the ass: "Get out!" Be honest, there's something for you to do! ”

Shi Bao hurriedly grabbed Hawking and smiled: "Big brother, don't worry, since Mr. said it, it must be a big deal, let's be patient for two days, and then there will be an opportunity to make contributions." ”

Hawking glared at Shi Bao: "You know a fart, what can happen in half a year?" If you stay in this place all day, you might as well go back to Chang'an or Shu County. ”

"Then you go back, hurry back, and don't dangle in front of me!"

Seeing that Su Ren was a little angry, Shi Bao forced Hawking out. Gongsun He said with a smile: "Just for a Sima and Qidu, fighting to be like this, I haven't seen the world in a fucking way, I think back then, Lao Tzu was ...... in Chang'an."

"That's it! Why have you started talking about it in your mouth recently, these are all curses, if you let Pingqu Hou hear it, you won't break your legs! ”

Gongsun He smiled: "Isn't it in Chang'an?" ”

Su Ren scratched his head, he was speechless for these three people. One by one, they have an angry mouth, and they are all cheeky. In order to avoid them, Su Ren took Huang Shisan and a few guards to Shaping that afternoon, and he wanted to live here for a while, while working as a supervisor, while hiding in Qingjing.

The efficiency of the master father Yan is still within Su Ren's tolerance. On the originally bare sand, the shadow of the big city could already be seen. The ground has been cleared and the foundations of the city walls are being excavated. Piles of materials were haphazardly stacked within a square radius of ten miles. The people worked very hard, and the foundations of the four corners of the city wall were the deepest, and they were already made of stones more than a man high.

Looking at a large group of people shouting the trumpet, while struggling to drag the rope that tied the boulder, and transporting the heavy stone to the city wall little by little, Su Ren frowned: "Can't you make a few gantry cranes?" Not far from the woods, local materials, can be made quickly, even if there is no gantry crane, get a pulley set is not easier than this? ”

The master father lowered his head: "Gantry crane? Pulleys? These subordinates have never seen this! ”

"Stupid!" Su Ren snorted coldly: "Have you seen a catapult?" Lengthening the boom and making a big catapult is faster than building a dirt mountain and moving the stones up little by little! ”

Seeing that Su Ren was angry, the master father didn't dare to speak, and several craftsmen behind him looked at each other, looking at each other with a bitter melon on their faces. As early as the Warring States Period, the people of Chu used this thing to cause heavy losses to the 200,000 Qin army, and even caused Li Guang's ancestor Li Xinbing to defeat the city father. That battle established the catapult's status.

But with the fall of the Chu State and the prevalence of the Qin State Tiger Ben, the Han people once again forgot about this bulky guy. If it weren't for Su Ren's hard work to see the people moving stones to build the city wall, I'm afraid it would have been until Liu Ye of the Three Kingdoms came up with a thunderbolt cart to make things like catapults see the light of day again.

Breaking off a branch and squatting on the ground, using sand as paper and wood as a pen, Su Ren painted catapults and gantry cranes while explaining the production methods to the master father Yan and those craftsmen.

"These things are very simple, first of all, the projection car, is a lever, a beam, a standing log, if you feel that the standing wood is unstable, make a bracket, the beam is tied to the stone on one side, and the other side is to find someone to pull, this side pulls, you can send the stone to the city wall, the top of the catapult should be able to move left and right, so that it can be placed on the edge of the city wall, and the stones sent up can be placed there if you want to."

"There is also a gantry crane, which is a huge wooden door frame, with wheels at the four corners, which can move back and forth, the beam above does not move, do one or two wheels to fix up and down, and can slide back and forth on the beam, and a group of pulleys are suspended below, and the pulleys are wooden wheels, and the rope is wound around them, and the force of one more pulley will be reduced, of course, the speed of rise will also fall, and the pulley will do more, and one person can send a thousand catties of boulders to the city."

Several craftsmen were dumbfounded, and when Su Ren finished speaking, they threw themselves on the five bodies they admired, especially the carpenter's head, and even bowed to them. Master Father Yan was also surprised, he admitted that Su Ren had some skills, but he didn't expect to have such a high attainment in terms of ingenuity.

Su Ren looked left and right: "Do you understand, when you make this thing, you have to match the city wall, if the city wall is high, you have to make it bigger, if it is a low wall, make it smaller, who still has a question?" ”

Several craftsmen all shook their heads, and although they didn't understand the principle, they could still make it out in a simple way. Su Ren threw the branch in his hand and stood up: "It's okay, just do it immediately, I will see the results in three days, if there is any problem halfway, just come to me, we are building a city, there are more places to use these things, try to make it stronger, in case a big stone gets up, I can't afford it, then something will happen!" ”

"No!"

After sending the craftsman away, Su Ren let out a sigh of relief. Head north along the edge of the construction site. Since the morning, Su Ren has been walking around the construction site, and he has also eaten on the construction site at noon. When you see something that is not right, or that doesn't match what he thinks, you will guide him. The master father sometimes felt that what Su Ren said was right, and sometimes felt that what Su Ren said was wrong. But what happened just now was an eye-opener for him, and he had a lot of things to ask, and seeing that Su Ren didn't mean to speak, he could only hold it in his stomach.

Further on is the northern wall of the new city, almost next to the sea, and the rough sea can already be seen in the distance. There is also a small construction site over there, with a small number of people and a small place to build. The dozen or so wooden houses that have been built are particularly eye-catching, because the houses are very peculiar, and unlike all the houses of the Han Dynasty, these houses are similar to square boxes, if not triangular roofs.

"Where are the docks and docks?"

"Exactly, according to Changshi's instructions, all supplies will be given priority to this side, and in another half a month, the houses on the shore will be completed, and then people will be arranged to build the dock, this is a bay, the wind is small, and it is most suitable for docking."

Su Ren nodded: "How are the shipbuilders looking?" ”

"I've already looked for some, but they only build some small fishing boats, such as building boats and the like, and they are not very good at it! The subordinates have sent people to search around, and if there is a suitable one, try to invite them. ”

"Don't build a boat, it's top-heavy, there is only one way to capsize the boat when you go to sea, Ming ** will call the best people in the boatmen to me, I want to discuss with them how to build a sea boat."

"No!"

Su Ren stood at the top of the hill, looking at the dock for a long time and was reluctant to leave: "If you want to go to sea, you have to build a sea ship, our current ships have no problem sailing on the big river and the big river, the sea is not a big river, the big river, that place is dangerous and abnormal, there are three feet Lang without wind, if it encounters a storm or something, no matter how strong the ship is, there is a possibility of capsizing." ”

"Changshi has been to the sea?"

Su Ren shook his head: "I really haven't been there, but I've seen the power of the sea, and we are too small in front of the sea." ”

Su Ren fell into deep contemplation, and the master father did not speak again. After blowing the sea breeze for a long time, Su Ren reluctantly walked back. The construction site is busy, and under the stimulation of money, the simple Han people work hard. A gust of wind whistled up a puff of smoke and dust, and everyone quickly turned around and covered their mouths and noses with their clothes to avoid the blown gravel.

"Why is it so much dust? Can't you sprinkle some water on the ground? ”

The master father hurriedly said: "Forgive me for the long history, there is more sand and less soil here, there are not a few trees, the nearest river is the Yongjiang River, which is more than ten miles away from here, and thousands of people on the construction site are sent to transport water every day, and there is really no excess water sprinkled on the sand." ”

"How's that going to work? In the future, there will be people living here, not to mention the moat, and the draft can't be solved, how can people live? Send someone to dig Ho! ”

"Dig what?"

"Hmmm! Dig He, dig a river from the Yongjiang River, the reason why this place is all gravel, is because of the lack of water, Jiangdong is short of everything is not short of water, how to get here is so drought, the first few times I came to feel that something was wrong, and now I want to understand! Digging a river, whether it is through the city or around the city, there must be water, with this river, not only can solve the draft, there will be a population in the future, but also irrigate the nearby fertile land, a profitable thing must be done. ”

"Yes! Although it is only more than ten miles away from the Yongjiang River, it is also a big project, in that case, our city will have to be delayed. ”

"Even if it's delayed, you have to dig He!" Su Ren looked at the construction site: "Except for the four watchtowers and docks under construction, everyone else will put down what they are doing and dig first, people can't do without water, it's not a big problem to skip food for a day, and if you don't drink water for three days, you're going to die!" The matter was so decided, dig a main river first, and talk about the rest of the tributaries later. ”

"No!"

On this day, the master father was exhausted by Su Renxin's thinking jump, so he had to convene everyone overnight to discuss and adjust the focus of work. Su Ren also attended the meeting of the master father, he did not say a word, sat in the corner and watched the master father go about his work. Until the end, Su Ren patted the shoulder of the master father Yan and nodded with a smile: "When I go back to Chang'an, come with me, I buried you in this place!" ”

Hawking and Shi Bao chased him to Shaping, and Hawking also pestered Su Ren to let him go to the barracks. Su Ren was annoyed, pointed to the dock under construction, and said to the two: "The ocean is wider than the land, I want to go to the sea to go around, how about you two accompany me?" ”

"What are you doing at sea?" Hawking asked suspiciously: "The land is already big enough, isn't it good to gallop on horseback?" Going to the sea to drink water and feed the fish? ”

"I'll go! I'll go! Shi Bao excitedly raised his horsewhip.

Su Ren glared at Hawking: "It's not promising!" He turned his head to Shi Bao and said, "Starting tomorrow, the two of you will go to find those fishermen nearby and train the navy!" ”
