Cultivating In Secret Beside A Demoness

Novel Summary
Jiang Hao passed through ordinary people and was forced to be sold into the Demon Sect and became a disciple of the Demon Sect.
I wanted to cultivate with peace of mind to become stronger a little bit so that I could survive in the world of self-cultivation, but was “humiliated” by a female devil in every possible way.
There is a huge disparity in strength, and he can only endure the humiliation and survive, hoping not to meet each other again.
Without a backer, he was favored by the Demon Sect’s headmaster and was able to practice with peace of mind. When he became the chief disciple and met the headmaster, he was stunned.
Looking at the beautiful face of the other party, he couldn’t smile a little. Isn’t this the female devil?
