Yu Youwei, a college student, was deceived hundreds of times a year and awakened to the lie-turning-true system. She actually made cash withdrawals when she clicked on an advertisement by mistake, and successfully helped her roommates negotiate prices every time. Her ability quickly spread. She chose to hand it over to the state and relied on the system to make many impossible things come true, helping the country make breakthroughs in various fields and deter provocative forces. She also figured out the rules that the system must be based on reality and not be too outrageous. In the later period, the system gradually reached its limit, and the country's big bosses restrained their desires and stopped asking for too much. In the end, everyone designed to trick Yu Youwei into making the system disappear, leaving only the knowledge and abilities they had mastered. Although she lost her system, she gained connections, gained graduate qualifications, and started a new life.
