My Senior Brother Isn't That Cold

A cold-blooded assassin, a wooden man without feelings, is brought into the world of cultivation by his master. Gradually, he cultivates and discovers his own humanity, starting out as a heartless person. But then he sees that those whose humanity was once whole are losing it through their ceaseless cultivation. At last, Li Moke raises the sword in his hand and points it at the would-be Deity Transformation cultivator, now selfish and devoid of humanity, despite everyone's objections and disbelief.

“I traveled from west to east and found my humanity, while you traveled from east to west and cast yours aside. They all say I am cold and heartless, and that I shouldn't be so kind as to sacrifice myself. But I want you to know this: I believe kindness is the best medicine for preserving my humanity. That's why I came to kill you.”
