Li Tangshan listened carefully to the analysis and asked, "The bow of the ship is a cross-shaped anchor, and the rectangular one at the stern should be the rudder, right?" ”

Qiao Chui looked at Li Tangshan in surprise, he didn't expect that Li Tangshan still knew a lot about the ship, this rudder was used by them in the sea ship recently, Li Tangshan knew it, and continued to explain to Li Tangshan: "If you look closely, you can see that the rudder surface is irregular square, the rudder rod is fixed with a cross-shaped structure, and there is a hole at the top of the rudder rod, which is used to install the rudder handle, we have tried many ways, and found that this is the best and most labor-saving." The rudder surface is deflected by turning the rudder handle, so as to adjust and control the direction and line of the ship's sailing. ”

Li Tangshan nodded: "How did you find out why you did this?" ”

Qiao Chui seriously explained to Li Tangshan: "The original boat, because the hull was not large and the draft was not deep, the direction of the boat could be controlled with the penny of the boat or the oars of the rowing boat. As the hull grew larger, the direction of travel could not be controlled by the pennies and oars alone. If the big boat has to walk in deep water, it will not be able to hold up to the bottom of the river with a penny, and it will not be able to exert its strength. In addition, a large boat needs to use many oars, many people need to row, and a large oar needs several people to row, so it is not easy to use the oars to both row and control the direction. So it was divided into a paddle that was in charge of paddling and an oar that was in charge of controlling the direction. The latter type of oars is moved from the sides of the hull to the stern of the ship, which becomes the rudder. ”

Li Tangshan carefully observed that the ship was about 20 meters long and 10 meters high, and could carry about 10,000 catties of goods, which could be said to be a medium-sized ship in the Qin and Han dynasties.

Li Tangshan was in a good mood when he came back from Linghu, and soon received a notice from Ren Huan that everyone wanted to go to Poyang to hold a meeting on the southern expedition. After Li Tangshan said goodbye to Mei Juan, he went to Poyang with Wu Rui to attend the meeting.

Zhao Tuo's eastern front operations advanced very smoothly, all the way to the Longchuan territory (today's Longchuan, Wuhua), while Li Tangshan and Wu Rui frequently encountered huge resistance and suffered heavy losses when they took over the mess of Tuju's western front operations.

Poyang in the rainy season is full of rain and fog. The spring rain comes slowly, and it goes slowly. I don't know how long it took for the rain to stop, and the sky was still gray. The water of the duck pond is shallow and deep, and the weather is semi-sunny when the plum is ripe? Huang Meitian, eighteen changes. The rainy weather will look like a child's face, suddenly? Suddenly. Too? When the face is revealed, the sky is blue and deep, and the air is exceptionally fresh, but due to the excessive humidity, people are a little suffocated; the light is like a needle prick, to steam people through, this is a rainy and sunny season.

The generals soon gathered in Poyang City, Poyang is Wu Rui's hometown and his basis, Wu Rui, who had just suffered defeat, did not feel like returning home, but was worried and lost in his heart.

Li Tangshan and Wu Rui came to the governance office and saw Zhao Tuo waiting for Li Tangshan and them in the governance office. Zhao Tuo saw that Li Tangshan had arrived, so he ran over from afar and shouted: "Brother-in-law! Why is it so late! ”

Li Tangshan happily patted Zhao Tuo on the shoulder and said, "Yes, it's grown!" The body has also become stronger! Not bad! ”

Zhao Tuo glanced at Wu Rui, but the pot didn't open the pot, and deliberately showed off to Wu Rui: "Wu Rui, I heard that you have suffered a big loss from Jijun recently?" With thousands of people lost, how could I have been so unlucky that I didn't meet a decent resistance. ”

Wu Rui couldn't wait to find a hole to hide in, Li Tangshan also felt that Zhao Tuo was too big in his eyes, and he shouldn't be so exposed, so he hurriedly scolded Zhao Tuo: "Zhao Tuo, your wings are hard, don't you understand that failure is the mother of success?" The responsibility for this defeat lies with me, not Wu Rui, it is I who underestimated the combat effectiveness of the Xiqi people, so Wu Rui rushed forward. ”

Wu Rui saw that Li Tangshan was taking responsibility for himself, and said warmly in his heart: "No, it's because my skills are not as good as others." ”

Li Tangshan felt that he should not continue on this topic, so he asked Zhao Tuo: "How to rule the South Vietnam region next time, do you have any new ideas?" Occupation is a trivial matter, the key is how to govern. ”

Zhao Tuo didn't expect Li Tangshan to ask him these questions, and he never thought about this question: "Brother-in-law, what advice do you have?" ”

Li Tangshan also thought about guiding Zhao Tuo to take care of the common people and reduce the killing of the locals in principle, and after thinking about it for a while, he said to Zhao Tuo: "It is recommended to adopt the policy of "harmony with Baiyue", reuse the Yue people, respect the customs and habits of the Yue people, and advocate intermarriage between the Han and Vietnamese ethnic groups. ”

Zhao Tuo's eyes widened and asked a little uncomfortably: "Brother-in-law, I really haven't thought about this problem. How? Baiyue people are so aggressive, do I think Heji Baiyue can really be implemented? ”

Li Tangshan knew what Zhao Tuo was thinking, and the Central Plains orthodoxy was already doing it in his heart, so he criticized Zhao Tuo and said, "I don't know what your kid is busy with?" Do you really think that our Daqin people are much more advanced than Baiyue? In front of your garrison there is a kingdom of Tsulou, who has been here for 1,000 years, and they are also growing a large area of rice. Returning their warships, can we Daqin be able to make it? Or the technology of boiling the sea for salt, as well as their ocean-going navigation technology, etc., which one is not more advanced than our Daqin. If we want to take root and develop in Baiyue, we must be humble and learn from Baiyue people. ”

Zhao Tuo saw that Li Tangshan had never criticized himself so seriously, and knew that he had really provoked him. The attitude immediately turned 180 too far and said: "Brother-in-law, don't be angry! I'm kidding you! Tell me how to get along with the Yue people and make good use of the Yue people. ”

Li Tangshan saw that Zhao Tuo's attitude had improved, and said slowly: "There is no way to govern, it is to solve their daily needs and improve their living standards." Although life in the Central Plains is good, it may be suitable for the Lingnan area, and specific things should be analyzed in detail. It's about to be a meeting, don't wait too long, let's go in! ”

Everyone soon sat in two rows on both sides of the old general, and at this time, the chairs had not yet been introduced to China, and everyone was still sitting on the ground, which made Li Tangshan feel particularly uncomfortable.

After the old general Ren Huan was appointed as the new commander, he held a meeting of all the generals for the first time. Everyone first reported the progress of various places, and everywhere was the victory in progress, especially Zhao Tuo's road was advancing the fastest, and only Li Tangshan and Wu Rui suffered another defeat.

Seeing that everyone had already sat down, Ren Huan began to say slowly: "Generals, there are two things for you today?" First of all, because General Tu Ju's policy was too aggressive before, there were many deficiencies in the policy, which caused us to encounter heavy losses. Let's discuss what good policies we have. ”

The Blue Tiger under the command of the Blue Wolf Army said briskly: "Old General, the advance on my side is very smooth, and there is no difficulty on my side?" ”
