I spent fifteen years repairing heavy-duty trucks at a logistics park. With just one glance, I could tell that the newly replaced parts were defective. But the new team leader, driven by greed, refused to listen to my warnings and publicly kicked me out of the company. Carrying my toolbox, I joined a rescue team and used my years of expertise to repair imported equipment that even the experts couldn't fix. Unexpectedly, my former fleet soon ran into disaster, with multiple heavy-duty trucks losing control and teetering on the edge of a cliff. Putting aside our past grievances, I rushed into danger to save lives and made that greedy team leader pay the price.
