The Regressed Genius Player's Mythical-Rank Weapon Creation

With the death of Earth’s potential Constellation, the Crimson Eye is now bent on consuming the world. Simun Kim--an alchemist out of necessity, due to an inability to use magic--successfully transmuted the Philosopher’s Stone to stop this cosmic threat. But he still failed. As death closes in, the Philosopher’s Stone rewinds time, waking Simun in the past with one last chance to rewrite the end of the world.
