I'll Blow Your Head Off with One Punch

During the Qin Dynasty, order collapsed. Demons and ghosts are rampant, and monsters appear frequently. Dynasties, sects, aristocratic families, and evil ways are all mixed together. In a time of great chaos, human lives are like grass and grass, and people are struggling. Zhou Tong traveled through time with a blue stone mill in his mind. The evil spirits he killed would be projected to the stone mill and put on reins to grind. As the millstone rotates, martial arts skills also improve. As a result, he met ghosts and killed them, saw monsters and slayed them, and created his own legend in this troubled world.
