Siheyuan: Engineering Graduate Student, I Have to Go Home First

The green train kept swaying, and Lin Weidong leaned against the window and stared at the rapidly retreating fields, still feeling a little confused. Three days ago, he was still writing his graduation thesis in the laboratory. He had just received his master's degree and when he woke up, he was on this slow train. He was originally an industrial major with the same major as him, and his tutor helped him pass the seventh-level engineer certificate. Three days ago, I received a letter saying that his father bumped into the factory security department after get off work to arrest an enemy agent. The old man was a veteran and rolled up his sleeves and rushed forward. All eight agents were caught, but the old man himself also fell. In this life, he must go home first!
