Douluo Continent: Reborn as Tang San's Cousin

Tang Nianxiao, whose girlfriend was poached by a rich second-generation, went to a bar to drown his sorrows.
He was accidentally run over by a truck on the road and transmigrated to the Douluo Continent.
He became Tang San's cousin.
He discovered that he was actually the son of Tang Xiao and the former Holy Maiden of the Spirit Hall!
At the same time, three martial souls awakened!
The Pope and the elders of the Spirit Hall knelt and begged him to inherit the Spirit Hall.
Tang Nianxiao: "If I go to the Spirit Hall, what will happen to Tang San?"
The Pope declared, "Anyone who dares to harm Tang San is an enemy of the Spirit Hall!"
Tang Nianxiao: "Tang San and I don't have a teacher!"
Pope: I will personally be your teacher!
Tang Nianxiao: "I want masters to be our teachers."
The next day, ten Title Douluos were dispatched, and Grandmaster was brought to the Spirit Hall.
Tang Hao: ...
The Spirit Hall is offering its entire hall as compensation to Tang Nianxiao and Tang San. How can they possibly avenge this?
[Note: In reality, the male protagonist doesn't become a disciple of Grandmaster or Bibi Dong to train Tang San; the synopsis is just for show~ lalala]
