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!",The Thunder God Bear hugged Guan Heng tightly, "I won't do it anymore, let me go back! I still have to sweep the floor at Baiyun Guan!",Guan Heng was overjoyed: “So it’s just a motionless thing!” He thought to himself, since it can't move, I'll find an opportunity to take it down! Looking at its size and weight, I'm afraid I can't kill it with my bare hands. Where is there any weapon Damn! If only I had prepared in advance!”。
