Qi Yan felt a very comfortable wind blowing, and there was a loud sound of turning books in his ears, and when he opened his eyes again, he found that he was no longer in the original place, presumably this is the task world in the book. As soon as Qi Yan had the idea of wanting to understand the situation, he found that the plot of this world and the memories of the client poured into his brain.

This is an ordinary modern world, but the environment in which the client lives is not ordinary. The client has no name, only a code name called "Seventeen", Seventeen is a child who grew up in the killer training base, she is an orphan, she entered the base when she was seven years old, and then gradually forgot about what happened before the age of seven, and was trained to be a cold-blooded and numb killer. But she is not an ordinary killer, because she is a "cargo" that has long been ordered by a politician with a surname. Many large families have hostile forces eyeing them, so they will cultivate their own forces. Moreover, the children of the big family also need to be protected, and when necessary, they will need people to do some murderous things. These people did not worry about the killers and bodyguards hired from other places, so they specially trained some children, these children had no background and no attached forces, and only knew to serve their masters.

Seventeen's training base is the world's largest killer battalion, this killer battalion is known as "Killing Greed", Killing Greed itself has many powerful killers, they also take orders from others, and they will also charge a high salary to train killers for those big families. None of the killers they trained had any contact with the outside world, and they were all trained by greedy trainers, so they could be trusted. Seventeen is one of the killers trained by the Feng family, and they are trained strictly and cruelly every day until they are qualified, and they will be taken away by their own master, and Seventeen has known since she was a child that she will work for the Feng family with these people around her in the future, so for her, the only thing to do in this life is to obey the orders of the Feng family to do anything.

The story takes place after Seventeen arrives at the Feng family, because she is relatively young and not as ruthless as others, so she is just sent to be a bodyguard next to an unfavored son of the Feng family. This unfavored son is called Feng Lin, just the illegitimate son of Feng Ming, the head of the Feng family, who is outside, and has just been taken back to the Feng family. Although he was taken back to the Feng family, Feng Ming didn't like Feng Lin much, just let him return to the Feng family to enjoy a superior material life, and even didn't help him when he was excluded by his brothers, just let him fend for himself.

Seventeen is Feng Lin's personal bodyguard, so he naturally knows what Feng Lin has suffered, and even several times Feng Lin has been bullied by other children of the Feng family and scarred, only Seventeen has helped him. And because he couldn't hurt the Feng family, Seventeen could only stand in front of Feng Lin and be beaten for him, even if he was beaten to the point that his head was bleeding, he couldn't resist. Seventeen sympathized with Feng Lin in her heart, she didn't feel much uncomfortable when she was hurt because of him, but she was very painful when she saw Feng Lin being bullied.

In Seventeen's heart, he was originally such a person, just a killer, no matter how much pain he had, it was okay, but Feng Lin was obviously a child of the Feng family, not only did he not have the love of his parents, but he also did not get the treatment that the Feng family deserved. And in Seventeen's opinion, Feng Lin is a simple and kind boy, he has never taken the initiative to fight for anything, and he has remained silent after being bullied, and after Seventeen helped him treat his wounds, he would also give Seventeen medicine, and even after Seventeen was seriously injured for him for a long time, he went to his father for the first time to ask for a doctor to treat Seventeen. Seventeen knew how difficult it was for him to see Feng Ming once, and he also knew that he never dared to ask his father for anything, but that time he opened his mouth for her. So from that time on, Seventeen vowed to protect this kind boy.

A few years later, Feng Lin gradually became stronger, and he was favored by Yi Yun, the eldest lady of another big family, the Yi family, so he got the help of the Yi family. And while he has endured over the years, he has also changed a lot, not only stronger, but also ruthless. Seventeen thought that he had become like this for self-preservation, so he felt more sorry for him and tried his best to protect him.

She trusted him so much that she was willing to do anything dangerous for him, even if it cost her life. But she didn't expect that in his eyes, she wasn't even a weapon, just a thing that could be given away. Feng Lin and Yi Yun didn't know each other, and Yi Yun originally looked down on Feng Lin like other rich children, and always bullied him with others. But in a banquet, Yi Yun and others teased Feng Lin but Feng Lin was cleverly avoided, and even the people who were with her were all suffered, only Yi Yun was let go by Feng Lin, and since then she has a good impression of Feng Lin.

Feng Lin is a person who is very good at taking advantage of opportunities, he is good-looking, brave and strategic, and under his provocation, Yi Yun quickly fell. Under Feng Lin's plan, Yi Yun ** was inferior to him, and from then on, he was even more obedient to Feng Lin's words.

Seventeen was very puzzled that Feng Lin was with a girl who had always bullied him and looked down on him in the past, but she had always adhered to her duty and had never thought about opposing anything. But when Yi Yun bullied Feng Lin in the past, Seventeen helped Feng Lin make Yi Yun lose face many times, and now that Yi Yun is in love with Feng Lin, naturally he won't blame Feng Lin. But Seventeen is different, although she is only Feng Lin's bodyguard, she is also a girl, and she spends much more time with Feng Lin a day than Yi Yun, so Yi Yun is unhappy, new hatred and old hatred are added together, how could Yi Yun let Seventeen go. Seventeen's thoughts are much simpler, she just wants to protect Feng Lin, and the rest has nothing to do with her, even if she has faced danger with Feng Lin for so many years, she has already seen that he is more important than herself, and she doesn't dare to have any other thoughts. So in the face of Yi Yun's hostility, Seventeen could only try to avoid it and not provoke her, but even so, Yi Yun had no intention of letting her go.

Yi Yun is the only eldest lady of the Yi family, unlike Feng Lin, although she is a girl, she is very favored in the Yi family, so she has a lot of resources in her hands, so in addition to falling in love with Feng Lin, her only pleasure is to torture Seventeen. Seventeen didn't care about it originally, she just thought it was to complete the task, but as Feng Lin asked her to protect Yi Yun more and more times, she also felt uneasy in her heart. Until Feng Lin and Yi Yun got engaged, Yi Yun said in front of Seventeen that he wanted Feng Lin to give Seventeen to himself, Feng Lin nodded without hesitation and agreed, without even looking at Seventeen. The dignity that Seventeen had never cared about was trampled on at this moment, she felt ashamed for the first time, and at that moment she realized that she still had a trace of hope in her heart, hoping that so many years of companionship could be exchanged for a little care in Feng Lin's heart.

In the past, Seventeen was still by Feng Lin's side, Yi Yun tortured her and didn't dare to be too presumptuous, but now Seventeen is her person, she can play as much as she likes, just when Seventeen was still immersed in the sadness of being abandoned by her master, Yi Yun had already begun to change her ways, until finally when Seventeen was about to die, she also asked Feng Lin to come and see, in the face of Seventeen, who was scarred and dying all over her body, Yi Yun smiled happily and proudly, and Feng Lin had nothing but a trace of disgust in his eyes.

So Seventeen is very unwilling, although she is a killer, but she is also a human being, and she also has thoughts, she doesn't ask Feng Lin to be good to her, but Feng Lin shouldn't give her away, even if she dies at the hands of the enemy, it's better than dying like this. So she hates Feng Lin and Yi Yun, she no longer wants to be stupid and desperate to protect Feng Lin, and she doesn't want Yi Yun to be humiliated!
