Chapter 637 Building a City (8)

"Yeah, it looks like a sense of accomplishment when the towering buildings rise from the ground. When the city walls are built, I'm going to start rebuilding the buildings inside."

‘The city wall made of obsidian is indeed very strong, but if you go to the ground below the central tower where the sun never sets, you may find more. ’ Xiu Ruoyou seemed to have nothing to throw out an opinion.

Shen Yanxiao raised her eyebrows slightly, Xiu seemed to understand that the sun never sets? She didn't ask too much, just followed Xiu's words and came to the central tower where the sun never sets.

The tower stood in the very center where the sun never set. After so many years of wind and frost, although it was a little dilapidated, it roughly retained its original appearance.

Walking into the tower, the pitch-black steps were scorched black. Shen Yanxiao searched for the entrance that might lead to the underground, and finally found a hidden passage under a broken stone statue of the Demon God.

Entering the passage, Shen Yanxiao took out the condensing crystal to illuminate the surroundings. The narrow passage could only allow one person to pass through, and the damp walls around made people feel extremely cold.

The narrow corridor seems to have disappeared until now, and it spreads infinitely downwards with circular stairs.

Shen Yanxiao didn't know how long she had walked, when she finally felt a little tired, the stairs finally reached the end.

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

'Push it away. ’ Repair the opening at the right time.

Shen Yanxiao took a step forward, took a deep breath, stretched his arms and tried to push the stone door open.

But this Shimen, which doesn't seem to be big, is like a huge stone of ten thousand tons. Shen Yanxiao spent a lot of effort, but he couldn't push it a little bit.

"I'll go! What is this made of? It's so heavy!" Shen Yanxiao rubbed her sore wrists, she concentrated all her strength on her hands, but she couldn't push the stone door open. You know, her current strength would be broken with a single punch. Stone wall is not difficult.

'Put your hands on the door, I'll come. ’ Xiu’s cold voice sounded.

Shen Yanxiao followed his words and put both hands on the stone gate.

The next second, she seemed to feel a pair of somewhat cold hands covering her hands, a trace of coolness came from the palms, but she couldn't see anything.

Squeak.

The Shimen was slowly pushed open, Shen Yanxiao's eyes widened in surprise.

The coolness disappeared from her hands, and Xiu withdrew his power.

Holding the condensing crystal, Shen Yanxiao walked into the stone gate.

It was obviously sealed off for tens of millions of years, but torches were still lit inside the stone gate.

Inside the stone gate is a huge basement. The entire basement forms a circle. On the surrounding walls, there are torches burning with blue flames.

Without air or fuel, these torches still flickered.

‘This is the underground energy source where the sun never sets, have you seen 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, like a dusty pearl, dull and dull, even though the surrounding flames flickered, there was no reflection on it. It is like pure black, absorbing the surrounding light.

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

The crystal was not small in size, but it was extremely light in weight, Shen Yanxiao picked it up almost without any effort.
