Thousandth death of Li Fan [Xianxia/Time loop]

In his first life, he was a mortal who swallowed a mysterious stone and died of the plague. In his hundredth life, he was a hero who saved the world, only to be betrayed by those he protected. In his nine-hundred-ninety-ninth life, he was a demon who slaughtered millions, only to be erased by the Heavens themselves. Li Fan has lived the same thirty to forty years for thirty millennia. He is trapped in a cruel time loop, cursed by the Dao itself. No matter how strong he becomes, how many empires he builds, or how deep he hides, "Fate" always conspires to kill him before he can reach the peak. The Universe views him as a virus, and it purges him without fail. Now, Li Fan wakes up in his bed for the 1,000th time. But this time, silence greets him. The Cycle Stone fused to his soul has cracked. The energy is gone. There are no more resets. No more do-overs. If he dies now, he ceases to exist forever. Back in his fifteen-year-old body with garbage aptitude and zero cultivation, Li Fan stands on the edge of the abyss. He has lost his immortality, but he has kept something far more dangerous: The perfect memory of 30,000 years of his life experiences. He knows where every ancient ruin will open down to the second. He knows the fatal weakness of every Sect Ancestor. He knows which useless weed will become a divine cure in ten years, and which "genius" is destined to fall. The Heavens treat all living things as straw dogs? Fine. Then Li Fan will become the fire that burns the straw. Let the final timeline begin.
