"What's wrong?"

Under the stone wall a few meters away from the two of them, there seemed to be a row of words imprinted, shrouded in shadows, Lin Yan frowned, "This seems to be an oracle bone inscription."

"Emperor Hao, ban?" Chu Yingxuan said softly, her face puzzled, "What does this mean?"

"I don't know"

Halfway, Chu Yingxuan said to Lin Yan, "Break it."

Lin Yan was stunned, "Huh?"

"I mean, break this wall", Chu Yingxuan's eyes narrowed slightly, "Maybe we can crack the formation and go out."

"Good!"

Lin Yan asked her to lean against the wall behind her, turned around and walked over there, the flame flashed in her hand, and she walked towards the wall.

"Boom", a huge explosion sounded, and the entire stone cave began to shake, Lin Yan quickly walked over to support her.

The dust dissipated, Lin Yan waved his hand lightly, and a fireball was suspended in the air, illuminating the scene behind the wall, and in an instant, the eyes of the two widened, and their faces were full of shock, what is this?

"What is this?"

Walking through the long passage, Mu Yun suddenly stopped, looked at the black copper door in front of him, and opened his mouth in confusion.

His eyes stared straight at the pattern on the door, which, in addition to a carved fresco, was inlaid with a few small transparent beads in the middle, which seemed to be in the shape of a star.

Su Yu walked over, and a deep voice sounded, "Big Dipper Nine Stars!"

"Isn't it the Big Dipper, there are only seven beads on it", Mu Yun turned his head to look at him, puzzled.

"In the legend of China, in ancient times, it was the Big Dipper, but later two were lost, and people changed it to the Big Dipper, until now, you see that."

At the end of the words, Su Yu stretched out his hand and pointed to the location next to him, where there were two small grooves, shrouded by the surrounding murals, which were easy to ignore, but there were no beads on them, and it was obviously the figure of the Big Dipper.

Mu Yun was a little surprised, she really deserved to be a god, and she even knew this kind of unpopular thing, but she seemed to have seen this bead somewhere.

Wait a minute!

Mu Yun took out a bead from his backpack, which had fallen from the copper door before, and compared it carefully, "It's really the same!"

As he spoke, Mu Yun reached out and pressed the bead into a groove above, and in an instant, the bead was inlaid on it as if it was tailor-made.

Mu Yun looked down at the small groove below, "There is still one missing."

Su Hao looked the entire copper door up and down, frowning slightly, "It seems that another bead needs to be retrieved to open this door."

"Can't you force it open?"

If you use a hydrogen bomb, you should be able to explode directly, after all, even the hardest spar in ancient times can't withstand the destruction of black weapons in modern society.

Su Hao stepped forward, stretched out his hand and pressed the copper door, a layer of silver light flashed, slowly spreading to the entire copper door, and the surrounding space was a little distorted.

Mu Yun looked at him, his eyes narrowed slightly, and the aura in the air seemed to begin to fluctuate.

In the middle of the ring, Su Yu withdrew his hand and shook his head gently, "No, this is a bronze gate made by a meteorite, there is a special magnetic field inside, and the Big Dipper Nine Star Formation is added outside, if it is forcibly destroyed, it is very likely that the things inside will be destroyed together."

Mu Yun frowned, "Then what now?"

If they couldn't get in from this side, they would have to go back, but then they wouldn't be able to find an exit.

Sweeping his eyes around, Mu Yun walked to the left, just took a few steps, and suddenly, there was a "click".

The stone path under his feet was recessed, and the stone wall next to it slowly cracked, revealing a two-meter-high passage, empty and dark.
