The Immortal Emperor Was Reborn, and I Became a High School Student in the Island Country

Li Xiuyan, an urban youth, accidentally traveled to the world of immortality. With his unparalleled talent, he ascended to the world of immortality within two hundred years. It took him another five hundred years to approach the realm of the Immortal Emperor. However, he encountered an accident while going through the Immortal Emperor Tribulation and was wiped out. I thought everything would be lost, but my soul awakened in modern Japan - he possessed the body of a Japanese high school student, bringing with him all the memories of 500 years in his previous life, the immortal emperor-level soul, and a nearly complete reserve of magic weapons and pills to return to this apocalyptic era of thin spiritual energy. On the surface, it is an ordinary Japanese campus, but secretly there are monsters everywhere, onmyojis are ready to move, vampires are secretly watching, and international supernatural forces are competing - and he, the former immortal emperor, stands at the top of it all, overlooking all living beings. He just wants to keep a low profile and cultivate immortality, and at the same time make up for the warmth that he could not fully enjoy in his previous life. It's just that the women around him... Each one is more difficult than the last. "I just want to practice quietly, can you guys stop confessing?" (Harem + pretending to be a pig and eating a tiger + cultivating immortals + urban superpowers)
