I Solve the Supernatural with Logic, at the Cost of My Humanity

Logic is my only weapon against the supernatural, and emotion is the price I must pay to wield it.

When bizarre rules descend upon the world, Lin Yan is forced into one deadly instance after another. While others struggle to survive with supernatural abilities or a System, he awakens an even more terrifying talent: absolute rationality. He can break down every uncanny phenomenon into cold chains of logic and find a way to survive.

But every time he uses this power, a part of his humanity is permanently erased. After solving a sea of puzzles, he loses the ability to feel fear. After solving the mystery of a cozy home, he forgets what family means. The stronger he becomes, the closer he gets to turning into an emotionless monster.

Then he discovers he can use the accursed "emotion coefficient" to redeem precious memories of his late younger sister. He trades his cold humanity for warm recollections. With the blade of logic in hand, he faces the cruelest paradox of all: before he becomes something inhuman, will he still remember whom he loved?

This is a survival epic set in a world of the uncanny, where reason is the blade and humanity the fuel, as one man searches for a final trace of warmth on the edge of madness.
