Lord of the Two Realms Starting from the Lightless Dungeon

Lin Xingran, who graduated from college and failed to find a job, woke up and found that he, along with a quilt, a mobile phone and a slipper, had been thrown into a dark dungeon without sunlight. The good news is that he unexpectedly gained the ability to travel between the two worlds. The bad news is that the other side of the door is not Earth, but an interstellar city ruled by giant corporations, prosthetics, and neon lights. What's even stranger is that after the same item passes through two worlds, it will be re-translated by the rules of the world. The filter element of the future world becomes an alchemical filter stone to purify the curse. The soul-eating short blade in the dungeon becomes a nerve-burning high-frequency cutter. Magic crystals can drive starships, and cybernetic bodies can also be engraved with divine spells. So, Lin Xingran began to use the garbage from the two dangerous worlds to solve problems that could not be solved in the other world. From surviving in dungeons to building cities underground; from black market trading to traveling across the star sea.
