章 2118: Chapter 2011, the son of Heaven of the sacred mountain

Su Yu had never known what this key was used for, so he had always kept it by his side.

It was only today, at this moment of life and death, that he thought of this key that he had almost forgotten.

Big Thunder’s mother was from the Flood Dragon tribe, and the flood dragon tribe had always been part of the royal family of the Demon World.

Princess Pixin’s soul had once said that the first demon emperor’s concubine had carried the key to this box, and it had disappeared without a trace.

He vaguely remembered that in the great yu imperial court, a flood dragon once chased after Su Yu, saying that he had the aura of the imperial family of the demon world.

At that time, the only aura of the imperial family of the demon world on Su Yu’s body could only be that of the Great Thunder just now, right?

Therefore, the identity of the Great Thunder’s mother was very likely that of the missing princess consort.
