In his previous life, Lu Chen reached the peak of the Nine Realms as a realm breaker, but died at the hands of his three most trusted brothers. When he opened his eyes again, he was back on the third day of reporting for freshman year. The Heavenly Gate has not yet opened, the alien world has not yet invaded, and the people who betrayed him were just ordinary teenagers who ate barbecue, played games, and slept in in the dormitory. Lu Chen did not wait for the end to come. He pushed open the first heavenly gate seventeen meters underground in the east of the city in advance, obtained the gatekeeper's mark, and awakened the "spirit" that had been sleeping in the center of the earth for hundreds of millions of years. One hundred and thirty-seven heavenly gates, the Academy of Mysterious Science, the Void Seed transformed by the previous gatekeeper, and the hunters from behind the Deep Sea Gate all focused on him. In this life, he will no longer trust anyone with his life. Anyone who dared to push the door would be beaten back.
