During Those Years When I Was Cultivating Immortality in Marvel

Lin Xuan was a modern man who once traveled through the Cangwu Realm and cultivated to Mahayana eight hundred years later. After a cross-border experiment failed, he was spit out into the modern city by a space crack, and landed right in the middle of the battlefield between two power armors. He knows armor, but not Tony Stark; he knows technology, but doesn't know any Marvel plot. The realm fell, the cave was closed, and only one heart of the Zhaoxuan Sword remained. Lin Xuan originally wanted to use the technology of this world to regain his path to immortality, but the Ark Reactor, Asgard, Karma Taj and Infinity Stones made him realize that the universe here is far more unreasonable than the world of immortality. Tony: "You call this cultivating immortality?" Lin Xuan: "You stuff yourself into a tin can and fly into the sky. Do you call this science?" A monk who doesn't know the plot, starting from the night when Iron Man was born, rebuilds his own way, and also takes this timeline in a direction that no one knows.
