[No female protagonist + growth-oriented single male protagonist + non-refreshing text, if you mind, you may enter by mistake. If you feel that the early pace is slow, you can skip the chapter and read] There was once a true god in this world. But now, they have been forgotten. Outside the normal world in our eyes, there are only unknown mysteries. Dark areas, pollution, and alien beasts that consider themselves ghosts and gods wander on the edge of the shadows, eyeing the human world. There is such a group of people who wear "shackles" and walk on the backside of the world. They use their lives and courage to fight against the unknown existences and protect their peace. They are called the Sky-Binders, which means that even God is jealous of their talents and binds them. Their talents are judged by the number of locks. The more locks, the more possibilities. Generally speaking, seven locks is the limit of human beings. But I, Xiao Tianyang, am an unprecedented Nine Locks. And I also know that true gods still exist somewhere in this world.
