Jiang Ziya screamed in the fire: "If I'm not here to keep you company, you will regret it.",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. I've always kept it as a treasured relic from him, dear Guan..." Tony's face instantly darkened, revealing a sinister smile, "For world peace, for enhancing your abilities, I'll have to burden you a little! Thor, hold him tight! I'm going to get started!",At this moment, the sword embedded in the stone wall loosened. Stone chips rained down as the three-foot blade glinted with a cold light and was pulled out. Guan Heng gripped the sword, poised for action, and plunged it straight into the giant dragon's forehead. The blade sliced downwards, cleaving the dragon's body directly in two!。
