Zhou Nan and Yu Shen were still on the same boat they took from Yanjing, and the three hundred pro-army guards only brought Li Feixing's men. The boats in the river and the horses on the shore headed southeast in the spring at noon.

  "The lower you go, the more rivers there are, and the so-called Kowloon enters the sea, and the most lively place is the Sancha estuary in front. The Lu River, the Baigou River in the west, and the Wei River in the Southern Dynasty all converge there into a river that flows straight into the Bohai Sea. In the past, when the old Liao and the Southern Dynasties were on good terms, the cargo ships of the north and south were anchored at the mouth of the Sancha River, and tea, rice, salt, silk and linen, leather goods, Jinzhu mountain ginseng and so on were traded endlessly here. Yu Shen regained his previous enthusiasm on the boat and introduced him to Zhou Nan.

  "Is there a tax collector at the imperial court?" Zhou Nan asked Yu Shen that he was about to choose a town on the border as a place for border market transactions, wasn't the Sancha estuary that Yu Shen said just right?

  "There are tax collectors, that is, in Hexi, north of Wuqing, in the past two years, it has been the opposite of the Southern Dynasties, and there has been no business travel for a long time, so they just collect some salt taxes." Yu Shen pointed in the direction he came from and said.

  "You stole the Southern Dynasty, and that's where you passed, right?" Zhou Nan remembered Yu Zhongwen's words and asked with a smile.

  Yu Shen smiled, "At that time, I was bent on going to the Southern Dynasty, so I pestered the shopkeeper under my father, and it was easy to go there, and the shopkeeper followed me all the way until I came back." Yu Shen said easily, at that time, he didn't know how to coerce and lure, and the shopkeeper was helpless, so he risked his life to escort Yu Shen.

  "Why don't you set up a tax collector at the Sancha River? Aren't you afraid that there will be vendors who will escape the tax money? Zhou Nan asked with concern.

  "The mouth of the three-way river can't be made!" Yu Shen shook his head and said, "It's a border with the Southern Dynasties, and the old Liao and the Southern Dynasties don't care, and acquiescing to some homeless people living in the middle is considered a buffer." As for tax evasion, there are very few. The goods of the traders are transported back from the boats on the Lu River, and they naturally pay the commercial tax when they arrive in the west of the river. If there are people who evade taxes on dry roads, they will be sent to prison if they encounter officers and soldiers. Those who can do business here are all some wealthy, who is willing to lose their lives for tax money! ”

  "How far is the Sancha estuary?" Zhou Nan asked thinking about things in his heart. Even if he crossed over, he had never been to this place in his later life, and he was not familiar with it. However, he still knows that Tianjin, which has developed by relying on river transportation, is Wuqing to the north, and it seems that this Sancha estuary is the later Tianjin.

  "It's not far to the southeast." Yu Shen looked at the banks of the river and said.

  I went down the Lu River to the southeast, and after seeing the boundless white barren land on both sides for a long time, I finally had more rivers. The river in front has also become wider, and there are two more military ships on the river, which cross the river. On the east and west banks of the river, there is a military village stationed, and on the flagpole fluttering high in the camp, it is the banner of the Wansheng Army, and there are two flagpoles, one of which is fluttering with a dragon embroidered with teeth and claws, which is the dragon army of Taogu. On the other flagpole is a dragon with wings, which is Wang Shunzhou's flying dragon army. Wang Shunzhou's Flying Dragon Army assisted the Dragon Army of Taogu to guard the boundary of the Jiehe River that stretched for hundreds of miles in this area, as well as the sea line from the mouth of the Haihe River to Shanhaiguan.

  The people in the military village had already discovered the boats and men coming down from the upstream, and before Zhou Nan and his party arrived in front of the military village, a group of soldiers rushed out of the military village and greeted them. At the same time, a military ship on the river slowly caught up from the south.

  The leader of this cavalry army jumped off his horse when he was far away from Zhou Nan's boat, bent over his armor and saluted: "Xiao Sandao, the deputy general of the Dragon Army, has seen the king of horses!" ”

  Zhou Nan's ship had already docked, and Zhou Nan said loudly on the bow of the ship: "General Xiao is exempt." Come aboard the boat and follow me to the front. Xiao Sandao immediately handed over his war horse to his subordinates, and jumped onto Zhou Nan's boat from the shore.

  At this time, the military ship with the flying dragon flag hanging on the river has stopped in front of Zhou Nan's boat, and there are more than ten sturdy sergeants on both sides of the boat holding oars, and the military boat is firmly parked on the river, and there is a general wearing battle armor on the bow of the ship who salutes Zhou Nan loudly: "The deputy general of the Flying Dragon Army, Agori, meets the king of horses!" ”

  This Agori, Zhou Nan has an impression. When Wang Shunzhou formed a naval army, of course, he gave priority to selecting soldiers who had good water skills and could handle boats. But picking and choosing, most of them are mocking soldiers. This is to be expected. The Xi people have always lived in the area of Jianqi Mountain, near the sea, for generations, and in addition to the world-famous Xi Che, they can also build ships. I can build a ship, of course, because I need to sail a boat. If you can go to sea, you will naturally have excellent water quality. Therefore, the Flying Dragon Army, the last formed naval army, even the deputy general was a Xi general.

  Agori heard that Zhou Nan said that he wanted to inspect the boundary river, so he took one of his men and got on Zhou Nan's boat. Zhou Nan said: "I came here today, firstly, to see the situation of the Dragon Army and the Flying Dragon Army stationed along the border, and secondly, to see the situation of the waterways here, so that I can make plans in the future." ”

  Agoli introduced to Zhou Nan: "After passing the military village, ten miles forward, it is the mouth of the Sancha River. There are waterways and horizontals, but some boatmen, salt households, and homeless people live, and the Southern Dynasty dug ponds all over the south bank of the Jiehe River, and the roads were muddy and difficult to walk. There are few border disputes. ”

  "Let's go to the mouth of the Sancha River first." Zhou Nan commanded.

  Agori immediately ordered his subordinate to summon him. I saw that the soldier took out two red and blue colored flags, held a flagpole in each hand, and waved them at the military boat on which Agori was riding. Immediately, someone on the opposite military boat also waved the colored flag twice, and then the military ship led the way to the south, followed by Zhou Nan's big boat.

  After passing the military village on the bank, as Agoli said, there were more large and small rivers, and the surface of the Lu River under the boat also became wider, presumably other rivers joined in, so that the river water increased than the upstream.

  Looking to the west, you can vaguely see that there is a river in the west, which is almost going to merge with the Lu River, but the Lu River course suddenly makes a sharp bend here, flows to the northeast, and there are four or five miles of road, and the Lu River turns back and flows to the southeast, like the river bay that goes around outside Sanshui Village, but it is more than four or five times larger than the river bay.

  In the bay, there is also a vast white saline-alkali land, and there are no fields in sight, only some wild reeds on the edge of the river pond, and a few fishing boats. There are also some sparse villages, but there are no people in sight.

  "King of the Horses, this piece of land is the mouth of the Sancha River." Agori said to Zhou Nan: "In front of you, there is a canal in the territory of the Southern Dynasty, which meets this canal and flows straight into the sea, so it is called the mouth of the Sancha River. ”

  "Where do the people of this shore belong?" Zhou Nan raised his hand and pointed to the village road on the shore.

  "The villain and General Agoli led the troops up, the people on this shore do not get along, just fish and boil salt by themselves, and pay taxes when they should pay taxes, and now follow the old practice, this land, I Xinliao and the Southern Dynasty do not care, let them live here." Xiao Sandao said beside Zhou Nan.

  "Let's go, go up and have a look." Zhou Nan was thinking about the border market transactions, such an excellent place connecting the north-south canal, of course, he would not let it go.
