Valkyrie's Shadow - Chapter 3Birthright: Act 1,

What got summoned was the world’s strongest sociopath.

Everyone had the right to choose his or her life. Maybe many people wanted to live an ordinary life, but Qin Sheng didn’t want to be a mediocre man. He had practiced martial arts under the guidance of his grandfather in the Zhongnan Mountains since he was a child. After two years’ wandering life, he decided to settle in Shanghai, so he contacted Han Guoping, a rich businessman, and took the job as his daughter’s safeguard. He thought that he only needed to protect Han Bing. However, things seemed more complicated. He got to know that Han Guoping offended a powerful figure and his life might be in danger. What would Qin Sheng do to help the Han family? Would he turn the tables?

Passerby-A is increasingly dissatisfied with their small part in the drama. By chance, Luo Ran was born because of this one sentiment. Her purpose is only one – to add scenes!

If you want to add scenes, you have to be with people who have more scenes. And those who have the most, are the male lead!

In the imperial harem, she is the second-class maid-in-waiting who died early beside the female lead.

In the immortal world, she is a flower demon who was mistakenly killed by the female lead before she was transformed.

In the CEO world, she is the smart secretary of the President.

In the entertainment world, she is a singer who has nothing to do with the male lead.

Luo ran uses these identities to attack the male lead and fulfill the desires of passers-by A; to add more scenes!

TN:

Passerby-A = Anonymous person, someone unimportant with a tiny role.
Add scene = to add value to a role with more scenes.
