Become Invincible from Face-Slapping Lottery

After traveling through time, Gu Ruochen received a face-slapping lottery system. As long as he slapped his face, he could get a lottery worth the face-slapping value. He was originally a real person, but in order to upgrade and gain immortality, he could only slap him in the face everywhere. His life is either a slap in the face, or on the way to a slap in the face.
