The Shabby Gun in the Marvel Universe

Wang Qing accidentally stumbled into the Marvel Universe and gained the ability to travel through the Myriad Worlds. From then on, he roamed freely across the Myriad Worlds. He served as a special forces soldier and became the strongest soldier king; he became a Taoist priest and took down demons as if it were nothing. He exterminated aliens among the stars, slew gods with a wave of his immortal sword, and could annihilate entire constellations with a single thought.
