Don't Be Afraid, Master. My Disciple Will Take You to Kill the Immortal World.

[Fantasy] + [Multiple heroines] + [System] + [Master Wife] + [Rebel] + [Senior Sister] + [Master] + [Saint] + [Empress] + [Pretending to be a pig and eating a tiger] + [Beauty] + [Master] Gu Changsheng traveled through time and became the useless disciple of a villain elder in the world of immortality. Gu Changsheng discovered that his master was a hypocrite. He actually wanted to turn himself into medicine dregs, and even sacrificed his beautiful master's wife to practice martial arts? At a critical moment, the "Great Dutiful Son System" awakens! As long as you are filial to your master's "family members", you can get a hundred times the critical strike reward! "Master, you can retreat in peace. I will take good care of my wife and senior sister!" Facing Master's wife who was suffering from poisoning, Gu Changsheng extended a helping hand: "Master's wife, I am here to help you get rid of the poison. Please bear with it..." Facing the unruly and willful senior sister, Gu Changsheng came up with his family method: "Senior sister, an elder brother is like a father. Today I will discipline you on behalf of the master!" ... When the master came out of seclusion with great achievements in magical skills, he found that his family was gone and the sect had changed its owner. Looking at his wife and daughter nestling in Gu Changsheng's arms, the master was so angry that he vomited three liters of blood: "Traitor! You... Is this how you take care of your master's wife?!" Gu Changsheng smiled slightly: "Master, this is called - don't let the rich water go to outsiders."
