Dual Transmigration Gates + sci-fi + myriad universes + invincible protagonist + power fantasy + no female lead
Lin Chen, an aerospace engineering student, unexpectedly obtains a pair of gates that let him travel back and forth between two worlds. One step takes him into an apocalypse brought on by the Sun’s helium flash; the other keeps him on prosperous modern-day Earth. He can also unlock sci-fi universes from The Martian, Iron Man, The Three-Body Problem, and more.
He trades modern supplies for the advanced technology of The Wandering Earth and uses technology from these other worlds to solve apocalyptic crises. By combining heavy-nucleus fusion, the Ark reactor, and curvature drive, he grows from an ordinary research student into the helmsman of human civilization.
He saves The Wandering Earth from catastrophe, comes to the aid of his modern home in its time of need, and fends off threats on a universal scale! One gate links two Earths and countless dimensions, leading humanity out of desperate straits and toward a new beginning among the stars!
