Empress: the Empress Had an Affair with Me

[Female] + [Time Travel] + [Black Belly] + [White Moonlight] + [Fantasy] + [System] Su Yihe is a senior grassroots employee of the Quick Travel Bureau. He and his system partners have filled countless pits dug by authors, and they can just wait for the last mission to be completed before they can retire. But he didn't expect that the system would be moistened in advance, leaving him with a mess. When he opened his eyes, he found that he had traveled to a world of female immortals that he had never seen before, and had become the thousand-year-old nine-tailed fox demon suppressed in the Qingqiu underground in the book - the biggest villain in the book, the great sage of the demon clan. The good news is that his magic power is profound and the foundation is still there; The bad news is that he is sealed underground and unable to move. When he was about to cry without tears, a small white fox carved in pink and jade came over. He made a prompt decision, injected a trace of his essence into the body of the little white fox, and used her body to break out of the seal. But can anyone tell him why he met the protagonist just after he went out? And why is this plot getting weirder and weirder? It doesn't follow the plot at all...
