Lin Yuan is an ordinary security guard at the east gate of Jiangnan University. He spends his days drinking tea and dozing off, and everyone looks down on him.
But no one knows that he has cultivated for three thousand years, yet his cultivation level has remained at the "Mortal Realm."
A Golden Core demonic cultivator causes trouble? He slaps him flying.
The Demon-Suppressing Well in Kunlun cracks, and a demon is about to emerge? He leisurely sets down his teacup.
Only when an old acquaintance sends a blood-written plea for help does he sigh. "Three thousand years have passed. It's time to settle a few scores."
