"Honey, please calm down! This is my last set of medieval antique teacups." Tony sighed, "I was going to use them to impress girls...",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!",Suddenly, a bright light flashed above his head. He looked up and saw a sword hilt deeply embedded in the stone wall of the cave. The spot was right above the dragon's head!。
