My Soul Splits into Three Thousand, and My Descendants Fill the Immortal, Demon, and Monster Realms

The protagonist, Ji Xun, transmigrated here, and his soul underwent a mutation, awakening the [Reincarnation Soul-Splitting Art]. He could send a sliver of his soul into reincarnation, where it would be reborn as an entirely new life, regarded by his main soul as a "descendant." These "descendants" lived independent lives, but all their cultivation insights and extraordinary experiences would be relayed to Ji Xun's true self at specific moments, such as adulthood, breakthroughs into major realms, or death. From the start, Ji Xun was just an ordinary mortal. He split off his first wisp of soul and reincarnated as a disciple of a small sect. When this "son" distinguished himself in the sect's tournament, Ji Xun's true self instantly mastered all his cultivation techniques and took his first step onto the path of cultivation. From then on, he began "sowing" souls like crazy. One wisp of soul entered the demon race and became a fox prince with an ancient bloodline; another entered the demonic path and became a personal disciple favored by the Demon Venerable; one even joined his sworn enemy's sect by sheer coincidence, becoming the junior brother his rival trusted most. Ji Xun's true self sat securely behind the scenes, while simultaneously playing the role of a prodigy among the immortals, demons, monsters, and humans. Today, he would use his "demon son" identity to obtain a secret treasure; tomorrow, he would send his "demonic grandson" to snatch one first. When the world descended into chaos and the prodigies of every race emerged to compete for Heaven's Mandate, people were horrified to discover that whether it was the foremost sword cultivator of the immortal path or an unparalleled overlord rarely seen in the demonic path, both seemed to lead back to the same mysterious and unfathomable figure.
