Engineer Lin Zhou's diversion plan had its main credit taken by supervisor Zhou Cheng. After the client demonstration failed, Zhou Cheng demanded that he take sole responsibility. Lin Zhou refused the conditions of exchange, preserved the scene with colleague Chen Mo, and reproduced it item by item in front of client Xu Ning. The first improvement seemed successful, but boundary tests failed again. He actively left behind the bad result, continued verification with the arriving He Yuan, and ultimately won back clear contribution, reasonable authority, and the pilot leadership opportunity. The counterattack comes from verifiable ability and daring to speak the truth, rather than hidden family background.
