Iron Man suddenly chuckled dryly, speaking to himself: "My father participated in the rebirth plan back then, keeping a tube of the most original super serum. I don't know what side effects it has.

The giant dragon seemed to feel a breath of death approaching, roaring desperately, its voice shaking the walls, almost causing Guan Heng to fall!,Turning his head, he saw the sword still quivering in the ground. Guan Heng smiled and said, "You helped me slay the dragon. Let you experience the baptism of flames too!" With that, he drew the sword and plunged its blade into the fire pit!。
