The Boy with the Infinite Universe Dragon Tattoo

There are only two things Chang Pian is best at in his life: first, surviving when everyone thought he was dead; second, when everyone thought he was just an ordinary person, he had already taken everything he could. The dragon tattoo is on his body, like a sleeping heart. No one knows when it will happen (fantasy, low-key, King Gou, Shuangwen, rebirth, time travel, single female protagonist.)
