On the edge of overseas cities, as the city continues to expand, this place has slowly expanded to the seaside. This place, but Chi Nan specially selected, the peaks here are relatively short.

In order to be able to reach the seaside, Chi Nan forcibly used explosive shells to completely smash the vicinity and forcibly blew up a road. Now at the edge of the road, the pond is ready to build a port.

But when it came time to build, it was not possible to build a port here.

The current outside is too chaotic and strong, and in this place, the small lifeguard can still follow the current, roughly control the direction of its flow, and always be around. It's the same with some small boats. But the big ships will not work.

Once a large ship enters the water, even if it is made of life-saving wood, it will still be swept into it by the current and eventually torn apart. Chinan has conducted many experiments to strengthen the ship itself, but even if it uses the hardest diamond wood today, there is still no way. The water will not tear apart the diamond boat, but it will pull and shake constantly.

In such a place, let alone going out, it would be nice to be able to stand firm. Some veteran sailors are also bound to get seasick in this environment. The port of Chinan has also been experimented, and the calm water flow method of the lifeguard cannot be completely suppressed at all.

At most, the water flow on the surface can be quieted, which is the effect of a large number of lifesaving beams piled together. There is no way to do it underwater, and the current is still very chaotic and violent.

In such an environment, the pressure under the port is too great. Even if you use steel that doesn't rust, it may not last long. Now Chi Nan is sure that this place can really be entered and exited.

"I understand, the surrounding area of this island is probably affected by something and turned into a natural magic array. Although the magic pattern also has some special abilities, it is far from the magic array. ”

Then Chi Nan smiled: "But that's fine, with such a protective barrier, it is absolutely impossible for others to succeed in attacking our Holy Tree Island in the future." At least, they can't fly if they can't. ”

Sacred Tree Island is the name that Chi Nan gave himself to this island, because there is a sapling in his body, and he was originally going to call it Sapling Island, but because the name is not good, it was changed to Sacred Tree Island. Speaking of which, Chi Nan himself doesn't know what kind of plant it is, or even if it's a plant, because no plant is so strange.

But it doesn't matter if he doesn't know, at least he knows that this tree must not be simple.

"But my lord, are we going to use the airship only to go out in the future? The population is still small now, and if the population will increase in the future, if they all use airships, I am afraid that the transport airships will also be a large number. ”

Next to him, an official said to Chi Nan. These officials were selected by Chi Nan here to assist Lao Muka in management. With these people, it was much easier for old Mukako. The whole island has also become very organized.

The biggest problem now is that it is inconvenient to communicate internally and externally. Their side is in full swing, and in fact, the other islands outside are gradually discovering the changes here. After all, there are so many airships flying around every day, even if the airships are flying at high altitudes, it is impossible not to be detected. It's only because they haven't been able to get close that they let it go.

Now that this place has a good strength, Chi Nan plans to make contact with the people from other islands outside.

But what I didn't expect was that the road was opened, but there was no way to build the port and ships. Without these things, you would still have to use airships. However, with airships, the cost is too high and troublesome.

In fact, this is just the long time and difficulty of the airship to build. If you change to those means of transportation on the earth, you don't know how much gasoline will be consumed. Luckily, all these things consume is solar energy.

Chi Nan looked around, then pointed ahead and said, "If I remember correctly, there should be a fairly large island in that direction." ”

The official didn't even look at the map, he opened his mouth and said: "Yes, my lord, there is an island with a diameter of about thirty kilometers in that direction, which is not too big in this ocean, but it is not small either. ”

"The island is uninhabited, perhaps because there is nothing to produce. The subordinates remembered that there was only one species of crab and coconut on the island, but the land was not suitable for the growth of other crops. "The growth of plants, this is really nothing to them, as long as there is a home mother tree.

Chi Nan smiled, and then said, "Since we can't go out by boat here, then let's build a port city over there, let's go out from there." Chi Nan's words made the people around him surprised.

"But my lord, even if we build a port city over there, we still can't get out. Ships outside are also not allowed to enter. "Everyone has seen the situation before.

If you want to get out of here, you must at least calm the flow of water and reach the silver level of a single magic pattern, and it is still the peak of silver.

Chi Nan smiled even more interestingly: "Who said I was going to go out by boat, what I wanted was to go out." In the puzzled eyes of everyone, Chi Nan laughed: "Hahahaha, since we can't go out by boat, then let's build a bridge." We went in and out directly from the bridge so there was no problem. ”

"As for transportation, I'm going to design a plant that specializes in transporting things and people, and then use my neural brain to control the action. "Kinan thinks of buses and trucks.

Not exactly the same, of course, but the plant type. It is also impossible to use wheels underneath, in fact, with a lot of tiny legs to carry out the activity. Because the legs are small, there are many of them, and there will be no obvious bumps.

If you think it's slow, can you run over it? The plan for Kinan is to cross the sea.

"Build a bridge? Is it really possible to build such a long distance? "It's more than fifty kilometers from here to the other island. Never before has a bridge been able to be built for such a long time.

There is such a thing as a sea-crossing bridge, at least they have never seen it. Could it be that some kind of magic can do it?

"My lord, I'm afraid we can't do this kind of thing, we can't even do it by driving piles in the water. Old Muka spoke, and the others breathed a sigh of relief, not to let the adults whim.

"I don't need you, I can do it by myself. Forget it, just look at it. Although this bridge is large, it will only take a few days to build a port city on the opposite side. ”
