Dragon: I Brought Back a Heart from the Nibelungs

Six years ago, a bus carrying 23 people drove into a tunnel during heavy rain and disappeared. Three days later, 13-year-old Lin Zhou climbed out of the abandoned ventilation shaft and became the only survivor. During an examination at the hospital, doctors discovered a second heart deep in his chest. It is half a beat slower than the original heart, cannot be removed, and no one knows who it belongs to. Lin Zhou only remembered a station that did not exist on the map, the last train that stopped at 0:17, and his companions who disappeared one by one with the sound of the announcement. Six years later, the second heart beat again. On the same day, he received an acceptance letter from Kassel College. There, he met the arrogant Lu Mingfei, and also met the poor American guy on the hunter website who was urging him to settle the bill every day. Later, the poor ghost became the king of bronze and fire. The fate that was originally planned was deviated because of Lin Zhou's appearance. Old Tang did not disappear completely, Xia Mi did not die as planned, and the girl in the red and white witch costume finally waited for the sun the next day. But the more people were rescued, the faster the second heart in Lin Zhou's chest beat. Until 01:17 midnight, the last train that had been missing for many years came into the station again. The car door opens and all the dead people sit inside. They looked at Lin Zhou through the car window. "It's time to give our hearts back."
