Ordinary Taoist: My Invincible Sisters

Luo Feng was a young man who grew up in the mountains with his master. 
His family deemed him trash and threw him out when he was young. 
That is how he came to live in the remote mountains with his master. He was very mischievous to the point where his master referred to him as a god of plague. 
One day his master told Luo Feng to go down the mountain and go live in the city with his seven senior sisters. 
Learn under the guidance of each sister and only then would he reach a breakthrough in his cultivation.
Each of his senior sisters is unparalleled in their field and they command respect from all around. 
Their relationship is not harmonious though, especially when it involves Luo Feng. 
They constantly dote on him and are willing to destroy anyone that brings him trouble. 
How will Luo Feng survive city life and can he deal with the jealous attacks coming from his senior sisters' pursuers?
