MTL - The Rise of Space Technology - Chapter 217 , all crazy

Qiao Nan: Crap! I am your biological daughter, yet I am treated as if I was picked up from the streets. In fact, you treat me worse than that!

Mother Qiao: Qiao Nan, you are not as pretty or smart as your elder sister. You are not as blessed as her. You have no right to study, marry, or to have your happiness!

Qiao Nan: Why am I not allowed to study, marry, or to seek my happiness? I will find a man right now and marry him!

Qiao Nan is dumbstruck upon discovering that the man right beside her is a powerful figure in the quad—the person who has the most promising prospects to be the future Chief.

Qiao Nan stares at the well-built man in front of her. He has firm abs and cold, chilling eyes. She swallows the lump in her throat as she says her greetings, “Good Morning, Chief!”

He, since childhood, had followed the Foreigner to practice the Defying Heaven Art, entering the most secretive special forces and becoming a fearsome assassin that made others tremble at the mere mention of his name. After a single failure, he took early retirement, but he ended up as the personal bodyguard for a rich heiress, a school beauty. Accidentally provoking some mysterious Cultivators, he gradually unveiled a hidden world of Cultivation beyond the mortal realm...

Somewhere in the wilderness. As soon as Ruan Youqing cleared up the gangsters, he turned around and saw Mr. Shoufu who came behind him. Throwing away the meteor hammer he picked up casually, Ruan Youqing fell into his arms by coincidence.

Ruan Youqing looked shy: “If Master Shoufu hadn’t arrived in time, you Qing would have been in trouble.”

Ignoring the screams and wailing next to his ears, Master Shoufu who did nothing stretched out his hand to wipe off the blood on the girl’s face, Then he said without changing his face: “The world is getting worse, people’s hearts are not old. Miss Ruan still has to be careful in the future, after all…you are too weak.”

The gangsters: “…???”
