My Yandere Sword Spirit Relies Entirely on Barrages to Feed Me

After Su Wan traveled through time, his biggest worry was not that he had no talent, nor was he being hunted down, but that he was forcibly bound by a sickly sword spirit. Not only must he be coaxed, he must be smoothed over, and he will turn into a black man if he is not careful, and he is not even allowed to use other weapons! "If you dare to use other weapons, I will stab you to death~" Fortunately, he accidentally started a "cross-border live broadcast" - the more explosive the barrage, the more he was able to change the rules, change the judgment, and make the fatal situation a famous scene. So the audience was responsible for cheering, the sword spirit was responsible for killing people, and Su Wan was responsible for passing the level with his life. I thought this was just a barrage of survival and cultivating immortality, until he dug out the deepest secret of the world. It turns out that the so-called prosperity of the immortal world is an illusion, and the sword in his hand was not used to ascend from the beginning.
