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!",This is actually a giant black dragon!! Its massive body seems to be rotting, covered with maggots, and some parts reveal bare white bones! That smell, Guan Heng knows all too well!,This action was originally a whim. Who would have thought that when the sword touched the flame, it let out a joyful cry, instantly sucking up all the dragon's heart flames!。
