A hundred years later, when she saw him again, he had become Zi Ye, the young lord of the demon realm. She accidentally ended up owing Zi Ye a hundred thousand spirit stones and was forced to write an IOU. Just like that, Zi Ye became Yin Xiao's creditor. From then on, she fled and he pursued her, embarking on a lifetime of dodging debts and collecting them, fighting and falling in love...
