These words left Shi Zhan speechless.

Gongsun Yun thought for a few seconds, then nodded and said, "Okay, let's leave the Forbidden Ruins together."

When Shi Zhan heard this, his expression became complicated, but he didn't say anything.

"Walk!"

But just when they were about to break through the sky barrier, something strange happened!

Suddenly, a huge crack appeared in the ground.

"careful!"

Chen Yan reached out and grabbed Yu Changying who had fallen into the crack in the ground. He gritted his teeth and pulled Yu Changying up with force.

Pei Wusu, who was standing next to him, also grabbed Zhuge Youlin.

As for the Wuxiang team, fortunately Yin Siyan held Mu Wen back, preventing him from falling into the deep and wide crack.

"What's going on?!" Gongsun Yun's face changed.

Suddenly, a huge crack appeared in the ground at the location of the third layer of the sky barrier. It was about three meters wide and the depth was immeasurable. The ground shook violently, forcing them to retreat a distance.

At the same time, a huge crack in the ground also appeared at the northern and southern sky barriers.

Suddenly, black bones appeared from the cracks in the ground, and then quickly gathered towards the sky.

Under the shocked gazes of the crowd, they saw the black bones quickly pieced together into a huge dragon skeleton in the sky, and soon turned into flesh and blood, like a living black dragon. Its figure was as majestic as a mountain, and the air around it seemed to become oppressive. Invisible pressure emanated from it, making it difficult for people to breathe.

Wu Ying's slightly surprised voice came from Chen Yan's sea of ​​consciousness.

"This is the last Dragon Emperor of the Dragon Clan during the Primordial Era: Ao."
