When power must be bought with memories, would you choose to forget your beloved, or give up on saving the world?
Ling Ye, a modern history graduate student, accidentally transmigrates to the Xuan Yuan Continent and becomes the "fake genius" eldest legitimate son of a third-rank earl's household. His awakened "Cost Deity System" offers no exhilarating chance to defy fate. Instead, it forces him to make brutal choices: every ability he gains demands a sacrifice of life, emotion, or memory.
To purge a deadly poison from his body, he trades away his sense of taste for a source-energy purification technique. To defeat a powerful enemy, he spends ten years of his life to activate time reversal. To protect his allies, he permanently seals a soul link, sharing pain and life and death with his companions...
In a world where technology and magic coexist, he uses modern knowledge to improve pills, reform the army, and unravel the ruins of ancient gods. But he discovers that he is merely a test subject in the "Defy Fate Project." As the temple's conspiracy comes to light, the Blood Moon's shadow descends on the Southern Wilderness, and his counterpart from a parallel world becomes a dictator, Ling Ye must make the ultimate choice between humanity and power, protection and sacrifice, fate and rebellion.
This is no simple tale of leveling up, but an epic about cost and redemption:
"I lost my sense of taste, my hearing, even some of my memories, but I never forgot what I was fighting for."
When the System's prompt finally sounds: [Sacrifice all emotions to become the one who writes the rules of the new world?]
Ling Ye grips the Soul-Devouring Demon Wolf Blade in his hand, with the star paths of countless parallel worlds behind him.
"I'll defy fate on my own terms!"
Highlights: An unconventional System story, a fusion of technology and magic, an ensemble cast, and a multiverse narrative.
