In Marvel: Traveling Between Two Worlds, Starting with Demon Slayer

Lin Xian transmigrates to the freedom-loving land of the United States and gets three golden fingers from the start:

Five dimensional portals leading to other worlds, an infinite storage space that can hold any item, and the ability to sacrifice anything in exchange for a magical power of equal value.

Sacrifice an ordinary banknote and get a rare collectible one, making a ten-thousandfold profit!

Sacrifice an ordinary porcelain vase and get a thousand-year-old antique vase, making a hundred-thousandfold profit!

Sacrifice Demon King Muzan and gain superhuman regeneration and immortality!

Sacrifice Uchiha Shisui and gain pure Uchiha blood, awakening his own Mangekyo Sharingan!

Sacrifice Luffy and gain the power of the Sun God Nika Fruit!

Sacrifice Sukuna's fingers and obtain Malevolent Shrine!

Sacrifice the Infinity Stones and gain the power of eternity!

He rescues the kidnapped Tony Stark, joins the Seven as their secret benefactor, and has a heart-to-heart with Wonder Woman.

Looking at the world he now inhabits, a mash-up of Marvel, DC, and The Boys, along with the five portals to other worlds, Lin Xian falls into deep thought.
