The Hongsha river meanders to the southeast. The river is more and more gentle to the southeast, and the river surface has become a lot wider. The sailing speed of ships has slowed down a lot. The ships in Zhenbei city are just ordinary inland sailing ships. They often need to row with oars, and the manufacturing level of ships is also very limited.

When Su Lun came, he had sent people to the coastal countries in the south to recruit people. The inland river ships were OK and could be used if they made do, but the seagoing ships used for ocean trade could not make do. The marine environment was too different from that of inland rivers. Only wind and waves could not be compared with rivers.

Now, if Su Lun's boat gets to the sea, not to mention a storm, a wave can directly break up their boat.

Strong seagoing ships are indispensable for ocean trade. There are not many shipbuilding talents in Zhenbei City, and there are not any seagoing ship workers. At that time, seagoing ships need to be recruited from the south. However, there are some drawings of seagoing ships here. If we build qualified seagoing ships in the conventional way and use the technology of Zhenbei City, it is impossible without two years.

However, this is a magical world. Suellen can make a magical ship by relying on the power of magic, and compared with ordinary sea ships, ships with magical power are completely big killers.

Magic ships are expensive, but Suellen can afford them.

On the whole, the Hongsha river is relatively safe, but there are some guys who don't have eyes who want to attack them. Then, there is no more. More than 200 elite soldiers in the North Town, not to mention these wilderness tribes, can easily attack even a city of 10000 people.

Next, the troops in the north city of these towns easily wiped out five or six small tribes. The surrounding tribes were scared and trembled, and several even began to migrate. As for the lizard people in the swamp, after seeing the army in the north of the town, they hid far away.

At the beginning, Su Lun wiped out lizard people on a large scale. These lizard people still have a fresh memory. They were scared to death when they saw the banner of the north town. If Suellen had not been interested in the swamp, these lizards would have been cleaned up by him.

Continue to drive southeast along the river. There is a lush forest not far from the southern swamp. There has always been a semi elf group. This semi elf group has a large number of people, about 1000 people. This is the data left by those adventurers last time.

Su Lun wants to put this half elf tribe into his pocket. These half elves are natural archers and Druid Rangers. They have good strength and look good, but they didn't join the north town. The half elf tribe is the master of the forest. The best way for Suellen to subdue them is to rely on natural oak trees.

As long as Su Lun takes out the natural oak trees, nine out of ten of these half Elves will choose to join the north town. However, these half elves refuse to contact him now. Su Lun also wants to find a way to deepen understanding with them. He plans to let the half elves in the territory contact with this half elf tribe.

After Hongsha River arrived here, the river surface has been 300 meters wide, and many tributaries have extended on the main river. This area has abundant water resources, many lakes around, and the environment is very good.

However, there are still some water monsters living in these lakes. The appearance of the water monsters is very similar to that found in Zhenbei City, but they are larger. If other ships encounter these water monsters, it is estimated that they will sink into the river, but when they encounter Suellen, they are unlucky.

In fact, Su Lun didn't have to do it at all. Those semi elf magic archers shot directly. One ice arrow was launched. The water monsters in the river were instantly frozen. Then the barbarian warriors jumped up and directly broke the city with the ice with their sharp axe.

Next, the army in Zhenbei city began to clean up the surrounding water monsters. Other monsters can be let go. Water monsters must be cleaned up. This thing is too threatening to ship navigation. After ordinary ships hit, ships will be destroyed and people will die. If Su Lun wants to open up the business road, these water monsters must be cleaned up.

Most water monsters have their own range of activities. Creatures that take the initiative to enter their territory will be attacked by water monsters. Ships must pass here if they want to enter the sea. These water monsters don't care so much. They are sure to attack.

The army of Zhenbei city has cooperated very skillfully. Soon, a water monster was killed by them. Except that the useful materials on them were cut off, the rest were directly discarded.

"Your Majesty, you can see an island in the middle of the river not far away. When you see that island, we are almost at the mouth of the sea," said the adventurer as a guide nearby.

Su Lun nodded, and then took out a single telescope to check. Near the estuary, the river surface became very wide. The estuary is a huge trumpet shaped river. The more it goes into the sea, the bigger the mouth will be, and the river center island is in the middle of the trumpet mouth.

The island in the middle of the river is small, about two kilometers wide and four to five kilometers long. The island is full of weeds and trees. This island is very suitable for building a shipyard.

The ship passed near the island in the middle of the river. When it passed the sea, it saw the boundless sea at a glance. Seeing the sea for the first time in his life, Su Lun also felt a surge of emotion, and those soldiers and craftsmen who had never seen it were stunned. These people living inland could not imagine the vastness of the sea. Now they are shocked to see it with their own eyes.

Sulun asked people to pull the ship ashore. Everyone got ashore and prepared to build a camp. At the same time, the things transported on the ship also need to be unloaded.

Sulun is going to build a city by the sea to trade with the eastern continent. As long as it succeeds, the city will become the most prosperous city in Beifeng principality for a period of time.

After arriving at the seaside, sulun immediately sent people to cut down trees and build camps around. At the same time, he sent troops to search around. Since he was ready to build a city, it was natural to clean up the surrounding dangers.

A large number of soldiers and workers were assigned out. After a while, workers began to cut down suitable wood. Sulun chose a flat place not far from the sea to set up a camp. The soldiers in the north city of the town toured around and found no monsters, but sulun still didn't relax his vigilance.

The workers in the north town were very experienced. Before long, a simple camp was successfully established.
