System In Avatar: The Last Airbender

Xiao Feng was an agent of some kind of spy and assassination organization in our world, he was the best at everything, but due to a rare and seemingly incurable disease, he was executed by the same organization that raised him. The organization had told him that if he fulfilled all the imposed missions, at eighteen they would release Feng. Of course, this never happened, but now it had a ray of light, and it literally is. Although he didn't know it right away, he was in the world of Avatar! one of the few things that he can appreciate. Motivated by Aang and his friends, he wanted to travel the world and find his own path in life. With that in mind, he did his best for the organization so that one day he could be like Aang. - Avatar: The Last Airbender does not belong to me. - English is not my mother tongue.
