The day of the start of construction has come, the wind is beautiful, the sky is clear, and the day is peaceful. Joon is alone at home, slowly unfolding the drawings of the undersea tunnel he has designed for a whole year. He's going to accomplish a feat. Drawings are drawn with a pencil. There are all kinds of dense lines and small print. He was going to create the tunnel using a method that no one had ever used before. That is, to build an undersea palace. He knew that some people fenced off the seawater, then drained it, and built the tunnel with cement concrete in many layers and layers, and then backfilled the seawater. Others dig trenches in the sea, dig wells, send pre-made pipes down, bury them, and dock them. Humans in the world have a variety of needs, and therefore a variety of methods.

First of all, Jun's undersea tunnel needs to be built in a short period of time. Secondly, it is necessary to have oxygen, which can pass people, and thirdly, it is necessary to be able to transport the world's most important and precious pure gold to a designated safe place. Finally, he had another idea. When the Mayan Valley becomes a place polluted by evil spirits, Joon hopes that people can reach a safe place through the undersea tunnel.

Joon double-checked all the details again. All the materials he needs. has been stacked in the delta of the peninsula. Someone has already begun to refine the steel he needs. A huge pot with a large pot of molten steel boiling on it, and there was only one person boiling it. The man was covered in muscles like balls. The power is endless. His name was Samson. There was also a man on the ground looking at complex drawings, cutting wood. He is Luban from Maya Valley, and everyone calls him Little Luban. Joon's tunnel is an underground palace that combines steel and wood structures and stretches for 100 kilometers. Direct access to the interior of the gold mountain. There is also one most important person, the most important thing cannot be accomplished without her. She is the wife of Uncle Liangre, Xue Ning. She and Uncle Liangre are incompatible. Uncle Liangre has the power of fire, which can heat everything, and the snow is condensed, and the skin is like clotted fat, and it is very moving. She couldn't get even half a step close to Uncle Liangre, on a full moon night. Do not usually touch too much. Otherwise, she would have turned into a cloud of water. She has the energy to cool everything, in an instant.

That day, Joon came to him. Tell her she needs someone to turn the sea into ice that isn't too cold, and can't just drop in temperature.

"What is that state? She asked Joon. ”

"It's a semi-solidified state."

"Semi-solidified? Then I'm going to give it a try. "Xue Ning tried it a few times. Finally, a week before the big day, this goal was achieved. The seawater became semi-condensed. Then everyone exerted their force together, and the sea water collapsed in one direction at once, like a piece of cold cake being pushed into. They don't have to pump water or backfill. When the palace is built, it will be enough to push the sea back.

Finally, in the middle of the night, the sky was completely dark. The large white disc hung high in the air, and the wolf roared on the mountain not far away.

Joon put his hands behind his back, thoughtful. Pacing back and forth. "Let's get started."

So everyone worked together. Overcome difficulties together. The snow condensation turns the sea water into the shape of a cold cake. Everyone casts mana together. Pushed the sea water to. Then follow Joon's drawings. Assemble the underground palace little by little. Although only little by little. But soon a third was built. It took them just one night to build the 30-kilometer wonder of this world.
