Start by Issuing a Challenge to the Empress' Wife

Jiang Feng time travels to the dandy waste in Qingcheng, the world of immortality. When he wakes up, he finds that he is getting married to Luo Yunyi, the empress of the Heaven and Earth Sect, in the women's boudoir. Jiang Feng doesn't know what the empress looks like, and mistakenly thinks she is an old witch. He is about to cry without tears. He is about to hit the head of the bed when a mechanical sound suddenly sounds in his mind. It turns out that the time travel comes with a system - a god-level sign-in system. You can get rewards when you sign in, and you can also write a challenge to the empress! Jiang Feng relied on the system to practice step by step.
