Comprehensive Martial Arts: Sticking to the Teacher's Concubine Huan, Jiang Yuyan Forced Marriage

Travel through the world of mixed martial arts and become Wudang's little transparent Liu Chunfeng. I thought I could only rely on the sign-in system to get by, but I didn't expect to sign in top-notch items. I wanted to develop in a low-key manner, but the world did not allow it. The witch Huanwan relies on him, the saintly concubine Xuan owes him, and even the future empress Jiang Yuyan has become his "creditor". This wave of time travel has made a lot of money!
