Keeping Vigil for a Hundred Thousand Years, I Am a Student in the City

No one knew that the transfer student from Jiangcheng University who slept in class was the night watchman of the universe who had lived for 100,000 years. He killed the giant beast of the void that devoured the galaxy, sealed the ancient demon god that subverted the three realms, and kept the peace of the universe for a hundred thousand years. In the final battle with the Lord of Finality, he drove the core heart of vigil into the space-time rift, leaving only one ten thousandth of its strength. In order to regain his heart, he parachuted into Jiangcheng as a new student. He wanted to keep a low profile, but there were always people who didn't have the foresight to come to his door. The rich second generation drives a Ferrari to tease the school beauty? With a snap of his fingers it exploded into scrap metal. The chairman of the group threatened to make him disappear? The next day, I personally took my son and knelt down to apologize. Just when he thought he could find peace and regain his heart, he discovered—— The vigil heart he had been looking for for three months was actually in the body of the school beauty he saved casually. What's even more frightening is that the old enemy Demon Shadow, who escaped from him a hundred thousand years ago, has chased the earth with the army of darkness. Mo Ying: "Lin Ye, it's been a hundred thousand years, this time I want you to watch the person you care about most die in front of you!" Lin Ye: "I didn't kill you back then. This time, not even the scum will be left." [No system] [Single female protagonist] [Enjoy the whole process without feeling aggrieved]
