National System: I, Who Have Been Sleeping for Thousands of Years, Woke Up!

I grew up on a ** star, and I also survive here. Almost everyone on this planet has a system. Some can become stronger by scolding people, some can become stronger by pretending to be cool and slapping someone in the face, and what's even more outrageous is that there are systems that can make you stronger by sleeping. I don't have a system, I think I can become stronger through hard work. But the reality is cruel. There is no way to survive on this planet without a system. Until one day, I picked up an awesome system. I'm torn between using this system against its original purpose. This novel and its characters are purely fictitious.
