Deep Sea Sunshine is a group of unknown soldiers, lurking under the vast expanse of blue waves, quietly setting out and returning silently; This is a group of brave and fearless soldiers. Although the cabin is narrow and there is no sun or moon underwater, they have a heart full of heaven and earth, and a heart full of sunshine. The blue sea has a heart of peace, and the oath is silent. Heroic submarine soldiers gallop deep in the ocean, loyal guardians of the sunny sea. ——Editor's Third Class Sergeant Zheng Tongzhu "Eagle Eye" Challenge "Isn't this Class Leader Zheng?" Soldier Xiao Fan, who was studying the "Military Online" micro course on the Strong Military Network, suddenly noticed that there was a familiar face among the instructors teaching "Precautions for the Use of Submarine Radar Navigation" - Third Class Sergeant Zheng Tongzhu of a Navy Detachment in the Northern Theater Command. This is not the first time Zheng Tongzhu has appeared on the screen. His first appearance was on the stage of the CCTV program 'Challenge Impossible'. Challenge is impossible, it is the ultimate pursuit of every ordinary life... "When the host's words rang out, Zheng Tongzhu slowly walked onto the stage wearing a navy white dress. Waiting for him is an unprecedented challenge - 'Eagle Eye Recognition'. Zheng Tongzhu's task is almost impossible to complete in the eyes of ordinary people: on the nine small screens ahead, 25 frames per second will flash, and the challenger needs to accurately lock the target character that only appears 0.04 seconds from 13500 frames within 15 minutes. Zheng Tongzhu tightly pursed his lips, his eyes as sharp as eagles, staring tightly at the flickering screen in front of him. Quickly, amidst the exclamation of the guests on site, Zheng Tongzhu instantly captured the key frame and successfully completed the challenge. So it's really eye-catching! "The audience below exclaimed in bursts of admiration. And Zheng Tongzhu still pursed his lips, fine beads of sweat oozing from his temples. At first, faced with the invitation from the program team, Zheng Tongzhu hesitated for a long time: "The stage of the submarine soldier is underwater, I can do my job well, it's not suitable to participate in the program." The propaganda department of the detachment advised him twice, but he politely refused. Later, with the encouragement of the Boat Political Commissar, the low-key and introverted Zheng Tongzhu made up his mind to challenge himself and showcase the style of submarine soldiers in front of the people of the whole country. After returning to battle, Zheng Tongzhu continued to challenge the profession and tried his best to shorten the time for capturing effective information on the radar dashboard. He is well aware that for every second the time it takes to discover a target, the probability of winning on the battlefield increases by one point. However, faced with the profound and ever-changing nature of the sea, even with the most refined and refined tactics, one often becomes unprepared. Once, during an emergency mission, the submarine encountered heavy fog and had to leave the port at the designated time, posing a significant safety hazard. More than a dozen pairs of eyes looked at Zheng Tongzhu at the same time - without the bridge to look out, radar became the "eye" of the submarine. Zheng Tongzhu focused on capturing weak signals and constantly changing operating commands... During the several hour voyage, the submarine evaded dozens of various ships and successfully arrived at the predetermined sea area. This means that during this voyage, Zheng Tongzhu identified and judged at least hundreds of target situations. After ten years of sharpening his sword, Zheng Tongzhu has almost become a part of radar. In the eyes of his comrades, constantly facing challenges has become an instinct for him. (New News Agency)
