The Cold and Beautiful CEO's Personal Bodyguard

In general, the male protagonists in the King of Soldiers novels are almost invincible, but the male protagonist in this King of Soldiers novel is really too weak. He is called the boss of the King of Soldiers. He doesn't know how to fight in ancient martial arts. He can't even beat the old man Sun who is half-experienced in ancient martial arts. He has to run for his life like a bereaved dog. Moreover, he is terminally ill with leukemia as soon as he comes out of the scene. He is speechless.

Is it a single heroine?

Hopefully it will be a single female protagonist.

It's already said that it's a cool novel, so why does it still have a single female protagonist? I hate this kind of scumbag looking for a girlfriend the most!

It's pretty good, come on
