Seal of Iron Bones

It seems that Chen Xing'an has never been chosen by anyone in his life. His father used a paternity test to push him out of the door. For five years in primary school, no one played with him. During the three years of junior high school, he was always in the fourth, fifth, or sixth row on the class teacher's seating chart—neither far nor near, just forgotten by everyone. He thought he would disappear into the crowd like this. Until the second year of junior high school, an iron bone seal engraved with ancient patterns burned in his palm. He became a sharp edge. I had my first real friend. Later there was a second and third one. Five people, five Iron Bone Seals, held up a line of defense in a dark place where no one knew. The shadows are awakening. And the sister he personally rescued and named Chen Le'an was being swallowed by it inch by inch. There was an emotion in her eyes that shouldn't exist. When a loved one becomes an enemy, when a young man who has never been treated well by the world must stand up to save the world - the Seal of Iron Bones will eventually ignite the last light.
