In the year 998 of the continental calendar, the black-robed chief mage **Yun Che**, known as the "Son of the Elements", was betrayed by his ally Crown Prince **Calander** during a spellcasting to fight against the crisis of annihilation, and died of a failed magic rampage.
He was reborn as a low-level magic apprentice with the same name thousands of years later, only to find that magic civilization had been completely "mysterious" - the rules were twisted, the old gods were awakened, the magic network was out of control, and all the magic in his memory was greatly reduced in power or even ineffective, and the entire empire fell into the shadow of weirdness and terror.
What's even more terrifying is that Yun Che discovered that deep in his soul, there was an indescribable **broken god** that seemed to come from the **"Lord of Mysteries"** world, which became the "golden finger" and the greatest curse that he could not peel away. It can respond to sacrifices and grant "evil version" of mysterious magical knowledge that transcends the times (such as [Flesh Shaping Technique], [Whisper of the Old Gods]), and it will also wake up periodically and demand a terrifying price.
In order to protect themselves, the imperial royal family (still descendants of Karander a thousand years later) sent the prince to the Holy See to become a "favorite of God" and regarded all unorthodox magic as heresy.
