The other officials did not understand Chinan's order. With their heads, they couldn't figure out how to build such a bridge.

However, they could not disobey the lord's orders, they could only obey them. So, the airship carried some half-elf nature mages with materials, and began to build ports and cities on the opposite island.

After such a long period of familiarity, the natural mage cooperated with ordinary people to easily build city walls, plant home mother trees, and plan the entire city. Before it was even built, the port city was thoroughly planned.

After looking at the blueprints, the island over there is indeed very suitable for a harbor, and there are no reefs around. Of course, even if there is Chinan, I don't care. The ships made of King Kong wood are not something that ordinary reefs can damage. And there is no danger underwater, which is really good as a port.

Around the entire port city, there are more than a dozen locations just for the construction of a port. Chi Nan thought about it for a while, and simply built these places into ports, leaving only the place where the dock was built.

When Chi Nan made his move, they finally knew what Chi Nan was going to do. Piers?

The piers used in the south of the water are not ordinary piers that go deep into the water, so they directly avoid the undercurrents and dangers underwater. Chi Nan fused the floating balls into the inverted cone-shaped things that were flat at the top and pointed at the bottom.

Because the floating ability of the floating ball is set, these piers are firmly suspended in mid-air. When they saw these things, everyone finally knew what kind of bridge the lord of Chi Nan wanted to make.

When these piers were formed, patches of plants began to grow. First of all, slender vines and special branches, linked together on the piers, link them together as a whole.

When the weight reaches a certain level, the floating force of the piers increases, and the bridge is always held in this place. For this adjustment, Chi Nan installed a plant brain in each bridge pier. These plant brains do not obey the orders of anyone but themselves, and the only command is to control the height.

"Fortunately, these floating balls were all evolved in a directional way, otherwise it would not be easy to rely on so many piers to levitate such a large bridge. "The weight of such a big bridge is terrifying.

After it was completely linked, it was only then that the entire bridge began to be born. Fifty kilometers, even if there was no such long sea-crossing bridge on the earth in the previous life, Chi Nan was faintly excited in his heart.

The bridge deck is made of diamond wood, which is laid layer by layer. In order to avoid the thermal expansion and contraction of the bridge deck, Chinan can only make the bridge deck not a whole. The natural phenomenon of thermal expansion and cold contraction cannot be completely avoided even by adamantium.

Thick diamond wood grows to form the bridge deck and wrap the piers in it. Under the protection of the thick diamond wood, it is very difficult for anyone to damage the bridge. The thickness of this thing is thicker than that of an airship mothership.

The entire bridge is more than 200 meters wide, suspended in the air, and the whole thing looks like a rainbow, but the color is different. In order to protect the bridge, Chi Nan is still inside the successfully built bridge, and every other distance, a special home mother tree is integrated, leaving only the ability of the mother tree itself, and the big tree is integrated into the bridge.

On the surface, nothing can be seen. The whole bridge is a whole, and after the bridge was built as a whole, a large number of special floating balls were reintegrated on both sides.

After this step, the suspension of the entire bridge is no longer only dependent on the internal piers, but also the suspension capacity of the bridge itself. The inner piers became a backhand of the bridge.

Even if something goes wrong with the bridge in the future, the outer part is shattered, and the inner piers can still keep the bridge suspended.

The bridge starts from the outer road of Sacred Tree Island and extends to the top of Harbor Island, crossing the edge and penetrating into the center of Harbor Island. To enter the Holy Tree Island, you must enter the port island city.

By the time this step was completed, the outline of the port island had been largely established. At this time, Chi Nan had already noticed that there were often people around him who were approaching this place and seemed to be observing themselves.

Honan ignored them and continued to refine his bridge. The main body of the bridge was built, but it was only a framework. There are many other parts that are needed to form a real bridge.

For example, the guardrails on both sides, and the leveling of the central road. The sidewalks and lanes have to be divided, even if there are no cars now, even if no one cares about traffic rules or anything, but Chi Nan still plans it.

Moreover, the bridge is still two floors, the upper and lower floors are passable. The lower layer is an internal passage formed by the direct bending of diamond wood in the south of the pond. It's not open-air, only there are plenty of windows on both sides to see the view outside. This place can also be turned into a battle castle if necessary.

Because only the windows can be used as firing ports, it is impossible to enter and exit other places.

Even with the current strength of Chinan, it took a full ten days to build the entire bridge, which is really a huge project. For the sake of this bridge, Chi Nan put down everything else for the time being.

"Now that the bridge has been built, I'm afraid the port is about to succeed. Then it's time for our ships. In any case, our ships must crush the other ships. ”

For such a long time, Chi Nan has collected a lot of information about the three major families around him, and Chi Nan can also see how powerful their ships are. If in the past, the ships made by themselves and theirs had their own merits. But since there is a lifeguard, then their own ships are definitely not comparable to them.

"Hehe, if you want to test, then let's test, I'll show you what a raptor crosses the river. ”

However, just when Chi Nan was thinking about how to contact others, the Sea King family sent someone to contact Chi Nan first. The day after the bridge was opened, a fleet of ships came to the outer port.

"What, the people of the Sea King family, they are really anxious, I thought it would be a while before they came to contact us. Forget it, let them come. Chi Nan was still a little surprised when he heard the news.

Moments later, representatives sent by the Aquaman family appeared in their castle. This castle was built on the harbor island, and Chi Nan did not want others to interfere with the development of the sacred tree island for the time being.
