Universal System: Little Lady Through Time

Yun Qingyu was ordered to secretly investigate Hua Qianxue, but the more she investigated, the more something was wrong. He obviously has no spiritual power, so he must be a useless person no matter how he thinks about it. However, Hua Qianxue is making great progress in the opposite direction. By the way, she is still a naughty girl full of energy. Uh... What is this girl's background? Yun Qingyu couldn't understand, let alone marry her. However, after getting married, I learned that Hua Qianxue had a "universal system". What's even more incredible is that the "universal system" seems to have thousands of connections with Yun Qingyu...
