After more than ten days of travel, several changes of planes and ships, Ye Feng and the man with him finally came to a small island and began Ye Feng's nine-year hellish training.

On this small island, he really saw the cruelest side of the world. Ye Feng, who had just landed on the island, signed a contract of sale, and since then, he has known that he belongs to this organization called "Dark Prison", and after living on the island for a year, Ye Feng knows that Dark Prison is actually a terrifying killer organization in the dark world, and he has gradually adapted to life on the island from the initial fear in this year, not because of the improvement of life, but because of the numbness of nerves.

Life on the island, except for eating and sleeping, all the time is spent on various training. In addition to the physical training that you always have, the instructors here will also teach you all kinds of killing techniques. With a little time left, you'll learn the pronunciation and etiquette of various countries, after all, to be a good killer, you have to blend yourself seamlessly into all kinds of environments. All you can do on the island is kill and be killed. As long as you are capable, no one will punish you even if you kill the instructor. Of course, if you can kill an instructor, then congratulations, you have graduated, and you can get out of this island and be free again.

Of course, the freedom here is simply the freedom of action, and you will still serve the organization, and you must complete the tasks assigned by the organization. If a student who leaves the island after graduation loses contact with the organization for more than a month, or exceeds the deadline set by the organization for issuing a mission, then they will be relentlessly hunted down by the organization's countless killers. So far, no one has dared to escape from the control of the organization after graduation, because only they know that the organization is terrible, and they know that they can't live with good luck under the endless pursuit of the killers in the organization. In addition to being able to leave the island after graduation, the people on the island will also be able to leave the island after being assigned a mission. However, after the mission is over, you must return to the island again until you graduate.

The way to graduate by killing the instructor is too difficult, and none of the people who can become instructors are mediocre, they are all some experienced and very spicy old killers, so the students who graduate by killing the instructor are called "nightmares", which means that his growth will become a nightmare for all enemies.

Of course, if you want to graduate, there is another way, the students on the island are divided into many classes according to age, and only one person can be left in each class at the end, and this only person can be regarded as a successful graduation, and the rest of the class is just a stepping stone for the last person alive, and can only be turned into dry bones.

Ye Feng has lived a nightmarish life on this island for nine years, and you don't know when your companion will stab you in the heart. When Ye Feng was seventeen years old, he killed the last surviving person in the class except himself, and when he slept at night, he did his best to kill the instructors who came to attack him, becoming the youngest "nightmare" on the island.

The next day, Ye Feng applied to the high-ranking people on the island to leave the island. It was quickly approved, and asked which city he would be living in. Since the students who leave the island still have to serve the Hell, there are often tasks to be issued. The organization also considered the students as much as possible, and assigned some tasks not far from the city where he lived or the surrounding areas to him to facilitate completion, so there was an inquiry about the city where Ye Feng lived, and Ye Feng did not hesitate to choose Z City. In the afternoon of the same day, Ye Feng was put on a black hood by someone and sent out of the island by private plane. Wearing a black hood is also afraid that someone will leak the location of the Dark Prison Headquarters, when Ye Feng came, because he was young, he didn't wear a black hood.

Ye Feng, who returned to Z City, soon found out what happened after he left. After he left, his mother did continue to receive treatment, but her condition was too serious, and she died only two months later. And my sister finished college with the money left over from her mother's treatment. After graduation, in just two years, with his extraordinary strength, he was promoted to the general manager of Xinyue Book Company, a well-known enterprise throughout the country. What warmed Ye Feng was that since he left, his sister had never given up looking for herself. From posting missing person notices at the beginning, to later posting missing person news through the Internet. The way of looking is changing, but the heart of missing my brother has not changed.

After Ye Feng paid homage to his mother at the cemetery, he bought a house not far from the residence of his sister. When he lived on the island, from the sixth year, Ye Feng also began to take over some tasks, so he had some salary after completing the tasks. I have to say that being a killer is really a profession that does not worry about running out of money. After only completing a few tasks, Ye Feng had millions of deposits in his card. Ye Feng lived next to his sister's residence, and he had not recognized her for three months. He didn't want to affect his sister's life because of himself, he knew that he was no longer the ordinary Ye Feng he used to be, and now he no longer really belonged to himself, he just wanted to look at his sister quietly and protect her quietly, just like she protected herself from childhood to adulthood.

But several times, when I looked at my sister, I would be distracted for no reason, and she almost found her figure. He still remembered that the instructor who taught him once said that the most taboo thing for a killer is to have feelings, because with feelings, then this relationship will become the killer's Achilles' heel. This sentence has only now been deeply felt by Ye Feng, the fatal mistake of a killer like losing his mind, when he saw his sister, he actually made it several times.

What Ye Feng didn't expect was that just these few mistakes made his sister feel his existence. And my sister designed it tonight and led herself out. In the end, it was my sister who took care of me with my mother for nine years, and I recognized myself just by feeling. Looking at the person crying in his arms, Ye Feng did not regret coming out to save him, even though it was just a scam. Now that you know each other, let yourself take better care of her.
