Immortal, Owe the World Ten Thousand Years

Seventeen-year-old Ling Chen discovered that this was a world where he could cultivate immortality, so he worked hard to make up for his shortcomings and finally broke through the tribulation at the age of eighteen, gaining the strength to rival the Immortal Lord. But what about the opponent? What about the villain? What about the protagonist? It wasn't until the mastermind behind the scenes couldn't stand it anymore and was reminded of his fate that Ling Chen suddenly realized what happened. "It turns out that I still owe the world ten thousand years of history. No wonder you can't revive your spirit through archeology." "Sorry, I'll make up for it right away." "Ling Chen, I think you can still pick me up in your next life, is that okay?"
