MTL - Start with Batman - Chapter 80 Double Phantom

One-eyed Wolf Lecan is a skilled adventurer who has conquered many dungeons all over the world. He had been going solo for a long time, but in the last three years, he’s had a partner. That partner jumps into the black hole together with Lecan, and both go their separate ways as they fall into another world. Dungeons and magical beasts also exist in that world. After learning the native language, Lecan goes on a journey. Meeting a good teacher, Lecan studies medicine making and magic under that teacher, and begins his dungeon explorations for real.

When the last prodigy level esper on Earth disappeared, Earth was in deep trouble of becoming another species’ colony. The ordinary Han, with his intelligence and hardworking character, was able to make a fortune after “accidentally” stepping into the world of dark net, later purchasing an esper power crystal that brought him the ultimate power that changed the fate of the universe.

Dark net is a subset of the Deep Web that is not only not indexed by traditional search engines, but that also requires special tools like specific proxy or authentication to gain access. Dark net is not restricted by any law or morals, so the dark net market has everything that is prohibited by the law. Drugs, slaves, firearms, uranium, bioweapons, rare animals, human testing, assassination, and the list goes on. During the year of 2075 on Earth, Han Lang logged into the largest hyperspace dark net market, and our story begins.
