Jiang Li was originally a good young college student in the 20th century. One day he woke up and awakened the system, which told him that he had died suddenly last night. Only by traveling to various small worlds and completing tasks can he change to another world and live a new life. After traveling to Teyvat and completing the task, he was transferred to Demon Slayer. In the end, he was promised retirement and transferred to a place that was similar to his original world. However, there are many "doors" in this world. The other side of the door is a different world, a world of Pokémon. But the people in this world don't seem to know what Pokémon is, and they regard them as Warcraft. But what does it have to do with me...
