I Shall Be Everlasting In the World of Immortals - Chapter 25: The Demonic Cultivator Liang Shaotian

Among the demons, the supreme ones are called “Great Saints.”

Outer yard disciple of the Tiansang Spirit Palace, Xu Xiaoshou, had average talent. However, after coming out of his death seclusion, he realized that everything had changed. He had received a Passive System with many strange, miraculous passive skills: He would become stronger with every breath. He would become stronger when he got attacked. He would become stronger when he got mocked… Xu Xiaoshou was forced to shout, “Oh God, I don’t want to be like this either. Everything I did was because I was being forced to! I am so passive!”

The Year 1766

Disowned by her own family for their own reasons, she was taken in by a maid at the age of seven to work at the Carmichael's household. The Carmichael's were one of the respectable pureblooded family in Bonelake and like any other household, there were rules. Rules that needed to be followed by the servants and maids.

Like everyone else, she was reminded not to disobey the rules. But before she learns to walk in the shadows like the rest without a whisper, the Duke's young son calls her 'Bambi' and everything breaks loose.
