"Xian'er has also heard of Haicheng in the imperial capital?"

Wang Ming could hardly understand Qin Xian'er's inner excitement at this moment. Pen % fun % Pavilion www.biquge.info

A little girl who grew up in the inner courtyard of the palace imagined the bizarre and wonderful world outside every day.

"Of course. Qin Xian'er turned around and said as if endorsing, "Haicheng, the largest city on the Great Wall of the Leizhou Peninsula, where the mouth of the Xiujiang River is located. Take Xuantie as the city, the outer city is 100 zhang high, there is an urn city inside, and there is an inner city, which is higher than the outer city, one hundred and fifty zhang. Legend has it that the dark iron is dug by the Nu Mountain of Leizhou, and some people say that the dark iron is the bones of the ancient demon emperor, so there is a congenital suppression of the kraken. ”

"Demon Emperor?" Wang Ming had heard Song Que introduce Haicheng in detail, but he had never heard that Xuan Tie was transformed by the Demon Emperor's bones.

"Senior brother, I saw this from the book, I don't know if it's true or not. Qin Xian'er was a little embarrassed.

As he spoke, the building ship had already arrived at the bottom of the Haicheng Gate.

The height of the sea city, the momentum of the sky, from the high sky, the tall building ship is like a children's toy.

The city was brightly lit, and after a password was met, there was a heavy "quack" sound, and a large number of waves poured out on the surface of the river.

The gates are raised.

What shocked Wang Ming was that the gate was indeed transparent.

The walls of the city wall are so thick that they are more than a mile long, and a whole fleet of building ships can completely pass through the city holes.

Quack, after each transparent gate of the whole fleet, this transparent gate slowly descends, and after a while, the second transparent gate slowly rises, and so on, there are a total of three transparent gates, and it takes an hour for all of them to pass.

Wang Ming has a sense of traveling through time and space, as if he is back on Earth, and what he is doing is a cruise ship passing through the Three Gorges Dam, a miracle of human engineering. At that time, people will spontaneously sigh at the greatness of manpower, and the so-called magic power of "moving mountains and reclamation of the sea" is nothing more than that.

Wang Ming didn't expect to see such a majestic human building in this martial arts world.

All the people gathered on the deck, and the third, second, and first floors were full of people.

No one spoke, and no matter how talkative the person was, he closed his mouth at the moment, staring intently at the huge Xuantie city wall, and there was an inexplicable mood stirring in his heart.

"The legendary semi-translucent crystal. Qin Xian'er muttered to herself, her eyes were full of excitement, and she reached out, as if she wanted to touch it.

"Translucent crystals are said to be able to isolate seawater from fresh water. Song Que said later, "No one knows what the truth is." ”

Wang Ming said in his heart, no one knows, I know.

The craftsmen here accidentally discovered that the semi-permeable crystal has the effect of isolating seawater and fresh water, so they used it to make the Haicheng Gate, which is the so-called "knowing its use but not knowing the reason".

This is an example that proves once again that the world is in a historical stage of extensive exploration and practice.

In fact, the name "translucent" already explains its principle, that is, only water is allowed to pass freely, and other salts in the seawater are not allowed to pass through.

As a result, the semi-permeable crystal gate fell, even if the river water on this side of the Xiujiang River is lower than the sea level, the water flow is still flowing from Xiushui to the sea water.

To Wang Ming's surprise, the earth is often a semi-permeable membrane, mostly existing in living organisms, but he didn't expect that there is a mineral that also has this property, and this also proves that the world's abundant products and magical properties far exceed the earth.

As soon as the three gates are opened and closed, it is to prevent seawater from backing up, and always keep the interface between seawater and fresh water in the city wall. This is the first function of the sluice gate, which protects freshwater fish. Tsk, people's ecological protection is really in place.

At the bottom of the gate is an arc-shaped black iron, and it can be said that the whole semi-transparent crystal is inlaid in the arc-shaped seat of the black iron.

The gate falls, and finally coincides with the riverbed by the curved black iron seat, thus forming a completely closed space.

Song Que told Wang Ming that the entire city cave was integrated from top to bottom, that is, the riverbed was also made of dark iron, so as to ensure that the gate fell completely consistently.

Wang Ming knew that the main function of the semi-transparent crystal was to isolate the sea creatures from the freshwater creatures, which meant that it was almost impossible for the kraken to trace through the gate, unless the semi-transparent crystal was forcibly dismantled all the way.

However, this is not absolute, the guard alert is much lower in non-wartime, and it is possible for the Kraken to be attached to the merchant ships that come and go.

That's how Gulya got in.

A small number of krakens mixed in, Leizhou not only did not worry but also welcomed it, and the martial arts hall issued many tasks every year to clear the krakens mixed into Leizhou, and the majority of samurai flocked to it.

In addition to the three semi-permeable crystal gates, there is also a 100,000 jin pure black iron gate inside and outside the city wall, and these two giant gates will only fall in wartime.

In the outer city of Haicheng, the two gates of the city wall facing the sea have completely fallen, leaving only some very small flood outlets facing the sea.

Inside the vent are countless iron fences, all of which are covered with sharp serrations, so that the large kraken cannot enter. In addition, there are Kraken alarm devices in the flood vent and the main gate.

The gate of the outer city is called the Gate of the Four Seas, which means that it faces the four seas, and the gate they just passed through is called the Gate of Hope and Thunder, which means to look at the Thunder City.

Xiujiang passed through the sea city in the middle of the way and raised a more majestic city gate called the east gate of the town, which was 50 zhang higher than the two city gates, towering like a cloud, majestic and a mess.

There are three semi-transparent crystal gates in the city gate hole, and two 100,000 jin pure black iron gates are also standard inside and outside.

The fleet did not pass through the east gate of the town, as the semi-transparent crystal gate at the east gate of the town was being routinely cleaned.

Wang Ming saw many people coming down from the end of the gate with ropes hanging from the gates, and a wooden barrel was tied to their bodies, all like Spider-Man.

Hundreds of people hung ropes to wash a semi-transparent crystal gate at one time, and from a distance, it looked like a bead curtain had been installed in front of the gate.

Song Que told Wang Ming that these high-risk jobs were all criminal soldiers.

The ship left the main channel and bent through the tributary on the right to dock at a large pier.

"Disembark!"

At the sound of an order, more than a dozen ships docked at the dock at almost the same time, and a stream of people disembarked from the ships.

The last to come out was the sin army at the bottom of the wheel, there were forty or fifty people, all wearing sin suits, and the last was only a stretcher carrying two or three corpses, which was said to be a tired sin army.

After a day of rushing on the river, there were already casualties.

The building ship will dock at the dock overnight, and the next day it will turn back to Thunder City and continue to transport people and materials.

At this rate, when the war is over, there will not be a few sinners left who have stepped on the wheel pulp.

The flow of people converged at the side gate of the east gate of the town, and then led by the officers to enter the east gate of the town one by one with their cards.

At this time, dark clouds that obscure the sky and the sun come from the east coast, completely obscuring the moonlight and starlight.

A procession of thousands of people walked through the long side doorway and was greeted by a torrential rain of heads.

People had just seen the majestic Haicheng, and their hearts were excited, and they were poured cold by the pouring rain in an instant.
