Blood Shaper - Chapter 20Book 4:

Having a rough life growing up, Wang Tong had numerous dreams of living a better life. However, his alcoholic foster father sells him off as a space settler of the distant planet Norton for some pocket change. Soon after his arrival, the Zergs overran the planet and obliterated its defenses in a matter of minutes. What awaited Tong on Norton was more than just an unbearable environment – its gravity alone was five-times stronger than earth – there were also swarms of bugs, constant hunger, thirst, and desolation.

While he lives a year of total carnage and survival, humanity’s Confederation eventually overcomes the Zergs on Norton and the powerful survivor Wang Tong is given a recommendation to a once famous, but now dying military academy where he begins his life anew.

Kazura was selected as the winner on a lottery that he bought on a whim and received ¥4,000,000,000 (4 billion yen).

At the feast of the Gluttonous House’s auction, there was a little girl with an exceptional furnace constitution for offer at a sky-high price. Everyone wanted to lay their hands on her. Suddenly, the little girl in the golden cage opened her eyes, radiating a cold gaze. She was no longer cowardly.

She was the gold medal assassin of the 21st century, transmigrating to become the good-for-nothing humiliation that everyone bullied, third miss Nalan Hexi of the genius doctor’s manor.

Meridians completely crippled, no innate skill to cultivate? What is she afraid of? She is the exceptional miracle doctor, and these injuries were nothing in her eyes.

Ugly complexion, malnourished and sickly in appearance, no one wants her? She recovered her unparalleled looks with the blink of an eye and gained a dozen good looking men as bodyguards!

That overbearing man who’d been sticking to her since the auction. Who said I was destined to be yours? I am my own, no one can decide my future!

A certain man: Then I am yours, will that do?
