In the deep night of the mountains, the water vapor condenses and rises. The convoy of a certain battalion of the Rocket Army drove through dense fog on a winding mountain road. "Discovered a small group of 'enemies' in the direction of 3 o'clock, deal with them according to plan!" Suddenly, the voice of the commander came from the walkie talkie. When the personnel got off the car, went out to search, and successfully killed the enemy... not long after, the special situation was handled. While everyone was getting on the bus, driver Hu Rui dipped his fingertips in essential oil and rubbed and rubbed his temples. "Teacher, do you think my energy is better than that of Class Leader Zhang?" Hu Rui put the bottle back in his pocket and turned his head to look at Teacher Wen Xiang beside him. "If Zhang, the class monitor, is here, he can wipe the essence of wind oil onto his nose!" Wen Xiang smiled and finished speaking, hugging the steel gun in his chest and casting his gaze towards the dark night outside the window. This is the first day I went to this camp for an interview, and the battle lasted a whole day. Sitting in the back seat of the Warrior Command Car, this is not the first time I have heard them mention the familiar yet unfamiliar name Zhang Lianlian. "Who is Zhang Jie?" I asked the cultural and educational instructor in confusion. Upon hearing my question, he immediately turned around, almost without thinking, and opened his mouth like a bolt of fire: "Zhang Lianjie is a model, a model, and the 'toughest bone' of our battalion..." It turned out that Zhang Lianjie was once an excellent soldier of this battalion. More than 20 years ago, the unit's equipment was upgraded and replaced, and Zhang Lulu, as the leader of the control professional group, was responsible for revising the operating procedures of the profession. In order to quickly organize a training sample for his comrades, Zhang repeatedly searched for information and conducted comparative experiments. Just as the work was about to be completed, he fell ill. After being sent to the hospital, Zhang was diagnosed with acute leukemia, and the news shocked everyone around him. On the hospital bed, he handed over the organized operating procedures to his comrades and said, "I may not have much time with you. I will share my experience with you, so you can avoid some detours..." Unfortunately, Zhang's life was ultimately not saved. In that snowy winter, he fell like a straight poplar tree... Just as the story was told, a special situation came from ahead again. Boom! Suddenly, the equipped vehicle collided with an explosive device on the roadside, causing the vehicle to instantly lose balance. A private received an order to urgently replace the tire, but when the third screw was loosened, it could not be removed. Seeing the upper class soldiers frantically making a mistake in the order of removing screws, a young officer rushed to the front of the vehicle, took the air cannon from the soldier's hand, and installed the first two screws back as quickly as possible. Then, he used a wrench to hit the wheel hub hard, and smoothly removed each screw in diagonal order. The soldiers waiting on the side quickly stuffed the spare tire into the axle. In the midst of a burst of vibration from the wind cannon and steel, the special situation was resolved. "He is the son of Zhang, the squad leader, and Zhang Haoran, the deputy platoon leader!" The cultural and educational instructor pointed to the officer just now and said to me. Before I could take a closer look, this young and swift figure had disappeared into the mist ahead. In that moment, I was deeply moved. In the thick fog and the pitch black night, a picture seems to emerge before my eyes - a father who travels through time and space, walking far away, handing a high torch to his son
