A Wretched System That Only Came into Being After Daluo Jinxian

[System + Time Travel + Traditional Fantasy] System: "Host, you are still barely able to protect yourself, so please proceed with caution." Yun Longyu: "? I'm already a Daluo Jinxian." Then I thought about it, maybe this world really has as many strong people as dogs. It's only been eight years since I traveled back in time, so it's better to be a bit sleazy. "System, please come out and tell me why the ancestors of this world only have the Nascent Soul realm???"
