The Most Useless System in History

The saddest time travel, a mother gave birth to a single dog after 20 years, finally found a girlfriend, and they were dating and time traveled? Just travel through time and you give me the system? Give me a system and you give me a super powerful system! My system was slapped in the face! From then on, I started the most shameless road of being slapped in the face! There is no way, the harder you hit, the faster you will rise! See how I became the king of faces! Yes, I am known as: Mighty, Handsome, Genius, Little Miracle Doctor, Invincible King of Leak Pickers, China's First God of War, the Universe's Only King, Generation Slap King Li Ziqiang!
