Full Marks for Mecha, You Said the Author Went to Work as a Security Guard?

Traveling through a parallel world, Lin Xuan was bound to the "Military Industry System of a Great Power" and started to build a seventh-generation fighter jet engine with his bare hands as his graduation project. I thought I could directly send him to the national team, but who would have thought that this broken system is a loan shark! The material was advanced by the system, and the work was created with perfect marks. However, Lin Xuan owed the system half a million yuan, and if he did not repay the money on time, it would be cancelled. In desperation, Lin Xuan could only throw the fighter engine into the laboratory, run away with the bucket overnight, and work as a security guard in a high-end community with a monthly salary of 8,000. It doesn't matter if he leaves, the entire military is going crazy. … "What are you talking about? The national treasure-level genius who built the seventh-generation engine cannot afford to pay for laboratory supplies?" "Disappeared mysteriously? Someone took your place?" "What does it mean that a local academic tycoon has a son with the same name and submitted the same work?" With the intervention of the National Security Agency, military vehicles surrounded the entire city, and the crackdown completely descended. The military boss's eyes were red: "I want to see people alive, but I want to see corpses dead! Seal the school later and eradicate the chaebol! Pull the bolts of all the guns for me. Anyone who dares to stop them will be killed on the spot!" At this time, Lin Xuan was holding a riot fork and stopped at the gate of the community: "Takeaway is not allowed in. This is a rule."
