Xiao Hanyi accidentally transmigrates to the Marvel Universe and awakens a Superman template that lets him grow infinitely stronger just by basking in the sun. He acts without restraint, doing whatever he pleases: soaking up the sun over New York, casually stepping in during disasters, and answering provocations with a punch that blows his opponent away. S.H.I.E.L.D. wants to recruit him? Nick Fury threatens him? Black Widow tries to seduce him? Iron Man tests him? He doesn’t care about any of it.
