This Douluo Continent Isn't Right

Bai Mo woke up to find himself transmigrated into the world of Douluo Continent, but he discovered that this Douluo Continent was off. It was clearly the Spirit Hall era, yet the Silver Dragon King Gu Yuena appeared by his side, and he encountered a demon from the Demon Slayer world. With great difficulty, he self-awakened his martial soul, Golden Blood, and killed the demon, only to run into Meng Hongchen, Ye Guyi, and others from the Sanctuary Academy, learning the truth of the world. Bai Mo smoothly joined the Sanctuary Academy, and at the academy, he met Qian Renxue, who was supposed to be undercover in the Heaven Dou Empire. She was actually his senior. Not only that, he also met the soft and cute Xu Xiaoyan, the pretty and tsundere Wang Dong'er, and even obtained his first soul ring inside the academy's simulated universe, encountered his own Demon King Guardian-a possibly blackened Robin-and gained his first power.
