Conquering the north and south of the Yangtze River, they carried stones in their backpacks - learning to converse with rocks was the key to conquering the towering mountains. "Oh no, we've encountered tough bones again!" The air at the construction site was damp and sticky, and the trolley drill pipe collided with the rocks, emitting a piercing roar. Wang Yongfeng, the first level sergeant of a certain brigade of the Rocket Army, shouted in secret that he couldn't do well and began to change his control actions. This veteran, known as the "King Stone" by the officers and soldiers, has been dealing with Jianyan Lishi for decades. Wang Yongfeng cannot forget the scene of entering the construction site for the first time. That day, he stood in the distance and saw a huge stone lying in the middle of the excavation section, like a "blocking tiger" blocking the way forward. Several key cadres gathered together to discuss ways to crack the problem. The battalion commander firmly said, "It's just a piece of iron, and we need to gnaw it down." For more than 10 consecutive days, the party member assault team formed in the camp fought day and night, finally breaking the big stone and allowing the construction to continue moving forward. "You see, this is sedimentary rock, like a sandwich, stacked layer by layer; this igneous rock is different, like an iron block solidified by molten iron. They have different compositions and hardness, and when encountered during construction, they should be treated differently..." Wang Yongfeng spoke vividly, and his comrades listened carefully and attentively. "The longer you work on a project, the more you feel that every stone has language, life, and character. You need to learn to converse with them." Wang Yongfeng is usually a bit introverted, but whenever he talks about stones, there is always something he can't finish. In his second year of service, he returned from his studies as one of the first rock drilling rig operators in the unit. However, for the first assignment, either the section was uneven and had to be reworked as if it had been chewed on; Either it's encountering a hard stone and working hard without any progress... After half a day, he, who was originally full of confidence, felt a bit disheartened. Standing on the pile of rocks at the work site, the platoon leader pointed to the stones and said, "If you don't study them thoroughly, you can't become an excellent trolley operator, nor can you become a qualified missile engineer." He always remembered this sentence and put it into action. Over the years, Wang Yongfeng has gradually grasped the "temperament" of rocks and combined it with construction practice to summarize a series of excavation plans, improving construction efficiency. One year, the superior held a skills competition based on a construction battle. He was not only the first to complete the task, but also the first to meet the standards for hole depth, hole spacing, angle and other indicators. He accurately identified the fault zone ahead, helping the blasting player adjust the plan in a timely manner and avoid dangerous situations. In this way, he gradually became a recognized technical expert among the officers and soldiers of the entire brigade. Not long ago, the section he was responsible for drilling was once again rated as a "model section" for construction. As the saying goes, "one inch of excavation, one inch of danger" means that for missile engineers, dangerous situations such as fractured zones, mud and stones, and fissure water can occur at any time. They are constantly facing severe tests of hardship, fatigue, injury, disability, and danger. Once, during the construction of the rockburst section, he completed drilling and was having technical exchanges with the surveying and mapping personnel on the working face. Suddenly, with a "bang", a stone larger than a palm fell from the arch and cut a wound on him... "We missile engineers have a special emotional attachment to rocks, and sometimes we encounter..."
