Chapter 637

"Yes, the ten thousand Zhang high-rise buildings rise on the ground. I feel very successful. When the wall is completed, I will start to rebuild the buildings in the sun."

"The walls made of obsidian are really solid, but if you go to the ground below the central tower, you may find more." Xiuruo seems to have raised an opinion.

Shen Yanxiao picks his eyebrows slightly. Does Xiu seem to know about the sun? She also did not ask, according to repair words, came to the central tower.

The tower stands in the center of the sun. After so many years of wind and frost baptism, although it has been a little damaged, it retains its original appearance.

After walking into the tower, the dark steps turned black. Shen Yanxiao looked for the possible entrance to the underground, and finally found a hidden passage under a broken stone statue of the God of evil.

Entering the passageway, Shen Yanxiao takes out the crystal to illuminate the surrounding area. The narrow corridor can only allow one person to pass through. The damp walls around make people feel extremely cold.

The narrow corridor does not seem to have existed up to now, and it spreads down infinitely with the circular steps.

Shen Yanxiao didn't know how long she had gone. When she finally felt a little tired, the ladder finally reached the end.

At the end of the stairs, a simple stone gate stood in front of her. The two sides of the stone gate were carved with exquisite patterns. After thousands of years, it still showed the exquisite skills of the craftsmen to the visitors.

"Push it away." Fix the opening in time.

Shen Yanxiao stepped forward, took a deep breath, spread out his arms and tried to open the stone door.

But this seemingly small stone gate is like a huge stone of ten thousand tons. Shen Yanxiao has expended nine cattle and two tigers' efforts, but has not been able to push it.

"I'll go! What are you doing? It's so heavy! " Shen Yanxiao rubs her aching wrist. She concentrates all her strength on her hands and fails to open the stone door. It's not difficult to know that even if her current strength breaks the stone wall with a fist.

"Put your hands on the door, I'll come." The voice of xiulengqing rings.

Shen Yanxiao put his hands on the stone gate according to his words.

The next second, she felt a pair of cold hands covering her hands, a little bit of coolness came from the palm, but she could not see anything.

Squeak.

The stone gate was slowly pushed open, and Shen Yanxiao opened his eyes in surprise.

Coolness disappeared from her hands, and Xiu withdrew his power.

Holding the crystal, Shen Yanxiao walks into the stone gate.

Obviously, it has been closed for tens of millions of years, but there are still torches in the stone gate.

Inside the stone gate is a huge basement. The whole basement is in a circle. On the walls around it, there is a torch burning with blue flame.

Without air or fuel, these torches still flicker.

"This is the sunless underground energy. Do you see the black crystal in the center of the room?"

Shen Yanxiao looked at the black crystal in the center. It was the size of a person's head. It was like a dusty pearl. It was dim. Even though the flame around it swayed, it didn't leave any reflection on it. It is like pure black, absorbing the light around.

"What is this?" Shen Yanxiao walked over and picked up the dim crystal.

The crystal was not small, but it was very light. Shen Yanxiao took it up with little effort.
