The Demon God of Guixu: Three Thousand Years Later I Will Come to the World as a Demon

For three thousand years in the Northern Divine Realm, he was the supreme demon god who made the gods tremble; when Kunlun returned, he was a freshman at the Demon City University who was about to start school. Long Yuanhai, with silver hair like frost and a deep scheming mind, was never merciless in killing, but he fought back when the system seized his body, and returned to the earth with his peak cultivation in the Guixu Divine Realm. Over the course of a month, things changed and people changed. The missed calls on his mobile phone, his father's nagging, and the crisis of his high school classmate Chu Mengyao brought him back to the world he had not seen for a long time. There are no immortal cultivators in this world, only ancient warriors from hidden aristocratic families, and sword cultivators, body cultivators, and spear cultivators controlled by the Warriors Alliance. The blood value has become the standard for measuring strength? The corner of Long Yuanhai's mouth curled up into a sneer, and he raised his hand to open up the power of time and space. How could it be restricted by this mortal system? The "Guixu Magic Code" derived thousands of supernatural powers, and the "Dao Devouring Demonic Art" devoured all energy. Even if his cultivation was damaged, he was still standing at the top of the pyramid. Protecting old friends, breaking into campus, fighting against aristocratic families, and controlling alliances, he not only has to adapt to modern life, but also needs to redefine the meaning of "power" in this spiritually exhausted world. When the devil's shadow covers the earth, who can stop him? And what kind of storm will three thousand years of loneliness and obsession set off in this familiar yet unfamiliar homeland?
