My System Keeps Calling Me Stupid

My name is Zhang San, the most unpromising collateral descendant of the Zhang family. Other people's systems: Ding! Congratulations to the host for obtaining "The Ancient Star Art"! My system: Ding! It is detected that the host's IQ is offline, and it is recommended to rebuild it. Other people's systems: Come on, host, you are the best! My system: You are the worst host ever bound to this system, bar none. The spiritual energy is revived, ferocious beasts are rampant, the family is run as a company, and the strong are respected. My brother is the successor to the family CEO, and my sister is a cultivation genius that is rare to see in a thousand years. And I set up a street stall under the overpass in the old city, selling ancestral Dali Pills. When the urban management came, I ran faster than anyone else. Until that day, I discovered an ancient ruin under an abandoned well. Others can't understand the exercises on the stone tablet, but I understand them - "The True Explanation of Fishing in the Ancient Times". The core mantra is just one sentence: Never sit down if you can. From then on, other people's fights would be explosive, and a set of skills would be useless. I was in continuous flow, so I lay down on the ground and yawned, while the other person fell down from exhaustion first. A vicious beast attacking the city? I argued with the system. Family assessment? I argued with the system. Going to the stars, confronting extraterrestrial civilizations, uncovering the secrets of ancient ruins... I'm still scolding the system. This is a story about salted fish and leverage system. They broke up with each other, complained about each other, owed a lot of points, and struggled to survive in the city where the spiritual energy was revived. But in the middle of the night when the protagonist cannot see it, the system that has a tougher mouth than anyone else will quietly sigh—— "This kid... Looks exactly like me back then."
