You Fox Spirit, Are You Here to Repay Me or Get Revenge?

Eight hundred years ago, Lu Chengyuan, young lord of the Qingqiu Fox Clan, failed to survive his tribulation. He was rescued by a mortal girl named Lu Xingchen, who gave him a fire-warding pearl. From then on, he owed her a debt of fate.

Eight hundred years later, Lu Chengyuan finally found his benefactor's reincarnation: Bai Qiqi, a twenty-nine-year-old biology PhD. She was in the midst of an academic crisis, with her experimental data repeatedly going wrong and three years of research on the brink of collapse. But this was only the beginning. Her ninth death tribulation was fast approaching, and if she failed to survive it, her soul would be scattered forever.

Shen Du appeared in the name of repaying his debt, determined to take this death tribulation in her place. A fox who had cultivated for a thousand years, and a female PhD who didn't believe in myths, had three days to unravel far more than a single life-and-death tribulation. There was also the forgotten past, which, after eight hundred years, was finally coming to light.
