Haiyasha jumped into the trench, then stretched out, like a fish, constantly moving downstream.

The further down the sea, the greater the pressure. At this time, due to the existence of pressure, the resistance of the sea water will become very large, so there are already some difficulties when going downstream.

In this sea water, Li Tian could not move instantly, but Li Tian could control the water-avoiding beads with his mind. At this time, the aperture formed by the water-avoiding beads outside Li Tian's body has been compressed into a shuttle shape by Li Tian's mind, which can effectively reduce the resistance of the sea water.

He kept swimming deep into the trench. After nearly a minute, Li Tian finally saw the bottom of the trench.

On both sides of the trench are ordinary rocks, with bare and no trace of living creatures. At the bottom of the trench, there is a different scene. The sea is full of plants, and from time to time, strange-shaped fish will poke a brain out of the seaweed. After seeing Haiyasha and Li Tian, ​​they immediately hid in the seaweed.

Deep in the seabed, although Li Tian's vision was limited, Li Tian could see clearly about ten meters nearby. At the bottom of the trench, there was no ancient city except for the seaweed and small fish.

"Is there an ancient city under the sea here?"

"Don't worry, you'll arrive soon. The ancient city under the sea is just below this trench, but we still need to walk a little further!" said Haiyasha.

If there is an ancient city that was submerged in the sea due to the movement of the crust, Li Tian still believes that if the ancient city is built under the ground of the trench, then Li Tian has to doubt it.

But Li Tian did not speak, but continued to follow Haiyasha.

The sea yaksha seemed to have a smoother breathing when he came to the trench. In the sea grass, it was like a fish, and its body continued to walk forward along the trench through the sea grass.

After walking about a hundred steps, a huge rock suddenly appeared in front of Li Tian and Haiyasha. The rock was at least ten meters high, but the huge rock looked like a small stone from a distance in the trench.

I don't know if this boulder is due to the movement of the current, the invasion of sea water or other reasons. There are more than a dozen caves on it. The smallest cave is only the size of a fist, and the largest diameter is more than two seconds.

"At this time, this is the entrance to the ancient city under the sea! This ancient city under the sea has existed for thousands of years, but has not been discovered by humans. It is precisely because this entrance is hidden. Okay, come with me, don't be too surprised!" Haiyasha said with a smug expression on his face.

As he said that, Haiyasha crawled into the two-meter-sized cave, and Li Tian could only follow him.

As soon as he arrived at the entrance of the cave, Li Tian felt a powerful energy fluctuation. This energy was like the sea and the sky, giving people a boundless feeling and making people fear this energy in their hearts.

"What a powerful energy! If anyone can master this energy, then those 12-level zombies are just like killing them in seconds? Even the three corpses can probably be easily defeated!" Li Tian said to himself.

Continue to move forward, the entrance of the cave suddenly became tilted downward.

At this moment, a strong light suddenly appeared in front of the cave. It was like the light of the sun, shining into the sea water, illuminating the sea water in the cave into colorful colors.

This sleeplessness was so amazing, Li Tian was already a little surprised.

And at this moment, the sea yaksha crawled into the colorful sea water and suddenly disappeared.

Li Tian chased after him tightly. The next second, Li Tian's eyes lit up. When he opened his eyes again, Li Tian found that the light layer formed by his water-avoiding beads had disappeared, and Li Tian actually stood at the top of a tall spire.

"This... this... is this... this... the ancient city under the sea?" Li Tian swallowed and said in surprise.

In front of you is a city covering an area of ​​more than tens of square kilometers. This city is completely made of stones. The tall tower at Li Tian’s feet should be the center of the city. Looking around from this tower, the well-connected streets are horizontal and vertical, and on both sides of these streets are buildings made of huge stones.

The height of the tower at Li Tian’s feet is more than 300 meters, and the height of the buildings surrounding the tower is also about 100 meters.

Such a tall building is quite difficult to build even in the current earth world. After all, various construction factors need to be considered. However, these buildings are completely made of huge stones and there is no sign of reinforced concrete. However, the building has been strong after thousands of years and there is no sign of dilapidation.

Looking from this 100-meter building, it was about two kilometers away. Wherever the buildings suddenly dropped, the height was basically maintained at more than fifty meters. Going forward was five or six kilometers, and the buildings there were lowered again.

The entire ancient city under the sea is like steps. The more you walk around, the lower the buildings there.

Li Tian looked up and saw that above the ancient city under the sea was a sky that looked like a pot lid, and there were many white clouds floating above the sky.

Of course, there is no sun here, and the reason why this ancient city under the sea only has this kind of light is because of a basketball-sized bead on the top of the tall tower spire.

I don’t know what material the bead is made of, and it continues to emit light. This light is somewhat similar to the sunlight.

"Is there any human inhabited this ancient city under the sea?" Li Tianwen Haiyasha said.

The sea yaksha had already landed on Li Tian's hand, looked at Li Tian and shook his head slightly, and said, "Thousands of years ago, when I appeared here, there was no human existence. It seemed that this ancient city under the sea had been abandoned for a long time. However, for the past thousand years, this ancient city under the sea has not changed at all, almost the same as I was a thousand years ago."

"Haiyasha, in this ancient city under the sea, I can feel a powerful wave of power, and this powerful force seems to make me feel that my own strength has improved. How could you say that you are trapped in this ancient city under the sea?" Li Tian asked.

Haiyasha nodded and said, "That's right, when you enter this ancient city under the sea, you can feel that your own power has been enhanced. But you look up at the point where the spire of the tower is connected to the sky!"

Li Tian looked up and saw a small circular hole with a diameter of about one meter in the spire of the tower and the sky. The hole was extremely conspicuous and looked like a hole broke into the sky.
