Holy Son of Humanity, Even My Breathing Is Getting Stronger

It's over. I traveled through time and accidentally killed someone. What should I do? Just when Qin Cheng was panicking, he suddenly learned that the person he smashed to death was Hades, the demon who was a major threat to the human race. Not only was he fine, but he also accidentally became the Holy Son of the Human Race. Popular among the people, favored by the king. But Qin Cheng knew that he was just a bastard and couldn't do anything! At this moment, the system woke up. [The salted fish system is successfully bound] [Breathe for ten minutes and gain physical fitness +10] [Perform meaningless thinking (daze) for five minutes and gain learning power +5] [Move your fingers eight times in one minute, gain +8 combat power] [Do nothing and get all attributes +10] In this way, Qin Cheng gradually became the world's biggest boss from a salty fish.
