Evernight Observation

Three hundred years of eternal night. The city without light. Train in the dark. Sixteen-year-old Xu Tiankong had a dream. There were trees in the dream. There are thirteen pieces of the puzzle on the tree. When he woke up, he had a pattern in his hand. Then he was put on the train. On the day of his first awakening, he fell into a coma. When he opened his eyes for the second time, he found that he had been observed for sixteen years. What he doesn't know is—— It wasn't just people who were observing him.
