My Identity as a Time Traveler Was Discovered by the Players

When Bai Mo traveled to this world, it happened to be a thousand years of chaos, and the people were in dire straits. He started from the beginning, quelled wars, destroyed alien races, suppressed evil gods, and achieved supreme status. Many years later, when the troubled times ended, Bai Mo decisively put everything down, returned to the world anonymously, and opened a small inn. It was at this time that he saw a group of guys with names on their heads. "The monk uses Rejoice—LV1." "Watermelon contains no sugar—LV2." "The name was chosen anyway - LV9." Bai Mo: How is this a game world!
