The wedding of Guo Jia and Sun Qing was also held soon. After that, Gan Ning and Guo Jia also began to form their Eastern Expedition Army Command. Sun Quan saw that everyone was busy, the weather in August was no longer so hot, the autumn tiger was gone, and the people were also preparing for the rice harvest in the second season, so he thought about seeing the situation of the slaves building the city.

When Sun Quan came to the city wall, the first part to build the city was near the riverside. Because it was closest to Sun Quan's palace and a pier for the navy, it started from here first. Outside the city there were piers and some military facilities. There were no residents here. Of course, there were many business people here, but Sun Quan's plan was to withdraw from the city in the future.

When Sun Quan saw that the city gates built first were all built with cement and stone, no longer with mud and bricks, nor with big stones. This saved everyone a lot of effort. The key was that it was safer for those who were trying to test the work. Sun Quan looked at the shelves that he had seen in later generations, but he always felt that they were not strong enough because the people who were commanding the test work were quite far apart.

Sun Quan called someone to come and asked, "What's wrong with the shelves you are wearing? No matter how I think you don't dare to get close to you?"

The man immediately knelt down and said, "My king, I deserve to die, because before, everyone used ladders or piles of soil to pile up. After we built the city wall, we had to dig out the piles of soil. This was too troublesome. So the young man thought of making some wood and bamboo to make some shelves and ladders so that people could stand on top of the construction. However, because the tied ropes were not strong enough and sometimes they were easy to collapse, the young man stood a little further."

Sun Quan looked at it and said, "There have you been a few accidents? Did you die when you fell?"

"Ask my king, I fell to death more than ten slaves yesterday, but the construction progress was much faster than before."

Sun Quan asked, "Then why don't you tie up these racks with iron wire? Although slaves are not valuable, they will disappear after death. We should still cherish them."

"Iron Wire? My King, I have never seen this little guy before!"

Sun Quan also remembered that he could not make iron wires these days. After all, the craftsmanship level is limited, but iron nails can be made, and nails can also be made, so he said, "You go find a blacksmith, and then find the four treasures of the study, and we will get some things."

When the blacksmith came, Sun Quan had already drawn two things: nails and nails, and said, "This is two kinds of iron nails. You can make some molds of this nail, and then pour in the iron, and the same is true for this nail. With this nail, you can connect the wood and nail them with these nails. This is definitely stronger than the ropes you use. If you combine the nails with the rope, it will not collapse so easily."

When the blacksmith saw it, he said, "I, Wang Yingming! I, Wang, the villain suggested that this should be left to a large workshop for production. The small ones can make a few samples first. The production efficiency in a large workshop will definitely be very high."

Sun Quan smiled and said, "You blacksmith are good and quite knowledgeable!"

After Sun Quan finished speaking, he wrote a note and asked someone to arrange it. Then he took the people along the already built city wall. Although most of the places were not made of steel bars and the top of the city gate was also made of stone, there were still many iron bars in the middle. The entire city wall looked two stories high and four meters thick. There were passages built behind the city wall, and the city walls were up and down.

The city gate is made of iron, not raised up and down, but sliding left and right. There are iron wheels and tracks under the iron gate, and there are mechanisms inside. This one cannot be opened if it is from the outside.

Sun Quanyou looked at the concrete, and the outside was also painted very smoothly, and said to Li Sheng: "You try looking at the city wall with a knife and see how solid it is!"

After hearing this, Li Sheng looked hard with a knife. Li Sheng was so strong that the knife shook his arms a little numb. A big gap appeared on the blade. Li Sheng took the knife in front of Sun Quan. After Sun Quan looked at it, he looked at the faint traces on the city wall and said, "Very good!"

From the passage behind, climbing the city wall, and then looking at it, you can see some vague shadows opposite the river. Sun Quan suddenly thought that when the city wall is repaired, there will be more slaves and build a bridge directly on the river. It is probably an existence that has been praised by everyone in history. With this idea in his heart, he will naturally be unable to curb it.

At this time, Zhu Zhi also came over. Zhu Zhi was the part-time minister of the Ministry of Workers. He was under his jurisdiction to repair the city wall. Seeing Sun Quan looking at the scenery on the river, he said, "My king, have you remembered any good poems when looking at the scenery on the river?"

Sun Quan smiled and said, "Junli, you are thinking too much, I don't have the heart to write poetry. I am thinking about building a bridge!"

"Build a bridge? Does my king mean to build a bridge on the river? How can this be done? My king, how can we start working here in this surging river? If all the slaves are thrown down, they will probably be drowned."

Sun Quan said seriously: "Look, our city gate is made of arches, so that we can ensure stability on it. We also use stone arches to build bridges. As long as we build more arches and connect them, we can build a very long bridge."

Zhu Zhi felt it made sense after hearing this and said, "My king, if this is on the ground, it is still OK. How can we repair the middle part in the water? We still have to set up a frame to support it, and we can't do it."

Sun Quan said, "Junli, let me ask you, if we knock off the floor under the barrel, put the barrel in the water, knock it into the ground with something, and then the water in the barrel is separated separately, right?"

"Yes, separated by the boards of the barrel."

"Then we are scooping out the water from the bucket, isn't there any water there?"

"It's natural. The water outside cannot enter, and there is soil below and no water will enter."

"As long as we have a wooden barrel-like tool that is large enough, it will be enough to have a place to construct here. Can we build a pier in the middle?"

"My king is indeed OK. When I go back, I arrange for someone to test it. However, if the river is too deep, we may not have so much wood to make this thing."

"Then use iron sheet. Use iron plates and find a way to fix and seal the four large iron plates. The iron plates can be cast as high or long enough. It is difficult to find wood. We can cast iron plates, but they are heavy during construction and need to find a way to transport and install them."
