The Whole Internet Laughs at Me as a Madman, I Can Kill All the Ghosts in the World with One Sword

Everyone thought that Lin Yuan was a hopeless lunatic in Qingshan Mental Hospital. He talks crazy words and behaves strangely. Everyone despises him and laughs at him. No one knows that he is bound to the Zhutian Sign-in System. Sign in in the ward and awaken the yin and yang eyes. Sign in at the morgue and learn the supreme ancient method of suppressing evil. If you sign on the rooftop, your body will be immortal, and you can kill ghosts and gods with one sword. The doctor thought he was talking nonsense. The patients mocked him for being crazy. The masters of the supernatural bureau are at their wits' end, and a century-old evil has wreaked havoc on the whole city. Until that day. The city is full of evil spirits, and all living beings are in despair. The plainly dressed, seemingly crazy young man slowly raised his head. Smile lightly: "Ghosts? Gods? You can kill them all in front of me." From now on the world knows. In Qingshan Mental Hospital, there lived a supreme god-killing boss in the world.
