The morning sun pierced through the clouds, and the sound of machines' "dada" like a drum beat broke the silence in the umbrella vault of a certain airborne unit of the Air Force. Sergeant Liu Pai bent down and lightly brushed his fingertips over the surface of the parachute, his gaze falling on the folds and ropes of the parachute. A 'physical examination' related to life safety is quietly unfolding. In this department, the position of Liu Pai is somewhat different - umbrella bearer. Before his comrades set off for parachuting, Liu Pai and other paratroopers were busy in the operating room, skillfully picking up tools and accurately conducting a comprehensive inspection of the parachute. The status of each part of the parachute was recorded one by one; As his comrades soared into the blue sky, Liu Pai gazed into the air from the ground, hoping for their safe return. The position of umbrella keeper is very ordinary - their work is mainly concentrated in the umbrella warehouse, picking and sewing umbrellas. The position of Umbrella Keeper is extraordinary - in the eyes of Umbrella Keeper, these seemingly ordinary umbrellas are actually the "wings of life" of paratroopers. Every fold and rope of the parachute is closely related to the safety of our comrades' lives. Today, please approach these umbrella protectors with the reporter and feel their ordinariness and ordinariness as guardians of the blue sky. The dream in the umbrella vault "is to lift up comrades to win victory. The sound of the steel buckle biting is particularly clear in the silent umbrella vault. Liu Pai's fingers instantly stopped in mid air, his gaze fixed on the tiny crack at the end of the umbrella rope. Under the cold white light, the crack emitted a dim glow, like an umbrella silently sending out a distress signal. This is the third day of Liu Pai's independent task of inspecting umbrellas, and fine beads of sweat quickly soaked his training uniform. Umbrella Curry was terrifyingly quiet, to the point where he could even hear his rapid breathing, one after another, accompanied by a pounding heartbeat. Liu Pai never thought he would become an umbrella protector. Before enlisting, Liu Pai imagined countless times that he could charge forward on the battlefield with a gun like a special forces soldier in a TV drama. Those passionate scenes formed his longing for military life. Until the day of the descent, the moment he pushed open the umbrella vault door, his imagination was completely shattered. In the umbrella vault, piles of umbrella cloths are neatly arranged, and the sound of steel buckles and ropes colliding can be heard in the ears. Looking at these unfamiliar umbrellas in front of him, Liu Pai's sense of loss flooded his heart - the "battlefield" he was eagerly anticipating was actually this warehouse filled with umbrellas. The first sewing task gave him a warning. The crooked and twisted stitches are interlaced on the umbrella surface, and the damaged part of the umbrella surface becomes wrinkled due to repeated stitching. Class monitor Wang Wei squatted down and gently picked up a broken thread with tweezers: "Xiao Liu, listen, this sound is not right." Looking at the class monitor's focused expression, Liu Pai suddenly remembered the words he said when he first walked into the umbrella shed: "Umbrella protection is a job that cannot tolerate any carelessness, and every detail is related to the safety of comrades' lives." Since then, the night light in the umbrella shed has always been on very late. In the warm yellow glow of the desk lamp, Liu Pai studied at his desk repeatedly. He repeatedly reviewed the maintenance manual and practiced needlework on the discarded umbrella cloth. The rough fabric made his fingertips turn red from grinding, but he didn't care about it and focused solely on honing his skills. Effort will not be let down. Repeated practice has cultivated Liu Pai's solid professional abilities. That day, when he successfully repaired the main umbrella buckle for the 78th time, moonlight shone through the window and shone on the neatly stacked umbrella bags. At that moment, looking at the repaired main umbrella buckle and neatly arranged umbrella bag, Liu Pai's heart was filled with an indescribable sense of achievement. Zhou Yang, who joined the army with Liu Pai, once stared blankly at the sand and dust raised during the training of the skydiving team, with envy in his eyes towards the skydiving members. However, that experience completely changed his mindset. During an emergency nighttime mission, he saw veteran Wang Qiang inspecting his umbrellas inch by inch under dim lighting, holding a magnifying glass. Even the smallest threads are carefully handled by Wang Qiang. This seriousness deeply touched Zhou Yang. Since then, he took the initiative to seek advice from the veterans and followed them in learning how to fold umbrellas and perform maintenance. Before a drill, a batch of umbrellas led by Zhou Yang had a problem during the sampling inspection - the folding method of the umbrella bags did not meet the standards. The pressure comes with it. Zhou Yang plunged into the umbrella vault, the rough umbrella rope leaving marks on his hands. His hands were swollen to the point where he couldn't even make a fist, but he gritted his teeth and persevered, adjusting his folding technique over and over again. When he was tired, he would sit against the wall for a while, take a break, and then continue working. At the moment when his comrades successfully completed the parachute jump, Zhou Yang's tense nerves suddenly relaxed, and a relieved smile appeared on his tired face. Nowadays, as long as Zhou Yang lightly touches the umbrella surface with his fingertips, he can detect subtle abnormalities in the umbrella. In his notebook, there are maintenance records left by his predecessors. On the yellowed paper, every annotation is valuable experience. The morning sunshine shines into the umbrella vault, and another batch of umbrellas are about to follow their comrades to the "battlefield". Liu Pai and Zhou Yang exchanged a glance and nodded in agreement. The detection pliers in their hands make a crisp sound, which is their silent promise - to use the most rigorous attitude to protect every set of umbrellas and safeguard the safety of their warlike friends. The stories hidden in the umbrellas, the sweat soaked days and nights, let them understand that the 'dream in the umbrella vault' is to lift up comrades and win victory. There is only one standard for hundreds of processes: zero errors. As the dusk gradually darkens, it envelops the empty new recruit training ground. The simulated training steel frame is like a silent sentinel, standing silently in the dim light. Second level Sergeant Wang Ning stood at the edge of the high platform, gripping the umbrella model tightly with his palm and his knuckles turning white. The model sways gently in the wind, making subtle noises. Watch it! "He said as he pressed the model control button. The strong wind swept over the gravel, raising dust. The first model unfolds its umbrella wings, and the white umbrella surface falls steadily, tracing a safe trajectory. The other model suddenly lost control and trembled violently. The umbrella rope twisted into a knot in an instant and crashed to the ground with a sharp whistling sound. The new recruits instinctively retreated, with some instinctively covering their ears. Every umbrella rope is tied with a heartbeat, and every buckle is connected to life. ”Wang Ning rubbed the edge of the umbrella with her fingers and said to the new recruits word by word. On the surveillance screen, paratroopers flashed through the clouds like lightning, carrying the umbrellas that their team had folded and repeatedly checked overnight. In front of the screen, Wang Ning was fully focused on the entire process of his comrades landing. Whenever Wang Ning sees his comrades landing safely, it feels like he has personally experienced the parachute landing mission with them, and the cries of his comrades when they land echo in his ears. Over the past 9 years, Wang Ning has participated in hundreds of security missions. Unforgettable moments and images were engraved deep in his memory. During a training, the rainstorm hit the iron roof, and the incandescent lights of the umbrella shed were clearly extinguished in the wind and rain. The machine roared incessantly, folding umbrellas piled up into small hills, and newly arrived canvas bags flooded into the umbrella storage with moisture. Exhausted comrades took time to nap in the pile of umbrella ropes, unable to sleep soundly because they were still thinking about checking their umbrellas. Once, on a winter night when a cold wave struck, the temperature in the umbrella vault dropped below freezing point. The white mist exhaled by the umbrella keeper condensed into frost on the detection tool, but they still insisted on keeping their ears close to the locksmith. There was another time when a slight dull sound from a certain component startled Sergeant Wu Xing - the low temperature caused deformation in the metal structure that was difficult to detect with the naked eye. He immediately activated the constant temperature device and took turns guarding with his comrades wrapped in military coats until all umbrellas completed their adaptability testing. When inspecting the locksmith, Wu Xing holds the inspection tool and places his ear close to the part to listen carefully. Suddenly, his expression became tense. The rebound sound of a locksmith is half a degree higher than the standard. This subtle difference sounded like an alarm in his ears. Disassembling the precision structure reveals a rough steel wire. Almost, it could have caused a training accident. "His voice echoed in the umbrella vault, waking up his comrades who were trying to catch up. Everyone gathered around, sweating profusely. Each set of umbrellas goes through hundreds of processes. Each one embodies the hard work of the umbrella protector. The umbrella keeper has only one standard for hundreds of processes: zero errors, "Wu Xing wiped the inspection tools with a firm tone. On that day, on the training ground, the new recruits were conducting simulated skydiving training. The morning light shines through the clouds and falls on the earth. Those carefully maintained umbrellas are about to lift young skydivers into the blue sky. At the same time, in the parachute vault, the parachutists were still busy: bending down to check, carefully folding... On the invisible battlefield, they used their professionalism and steadfastness to protect the lives of the parachutists. The new umbrella has replaced the old one, and the style of the umbrella keeper is also inherited from the late night umbrella repair room. Under the incandescent light, the shadow of the second level sergeant Wang Ning is stretched long and reflected on the workbench filled with drawings and parts. He held the skeleton of the new umbrella and repeatedly rubbed the subtle patterns at the seams with his fingertips, as if conversing with the cold metal. Wang Ning is researching the performance of a new umbrella. Click... "He turned the screwdriver, and the sound of metal friction pierced the silence. Only by constantly learning can we keep up with the pace of the battlefield, "Wang Ning buried his head in the pile of equipment before he could finish speaking. In the adjacent studio, Corporal Wang Wei's forehead was glistening with sweat, and his eyes were fixed on the umbrella rope fibers under the microscope. The flaw in the umbrella discovered before the exercise was like a thorn piercing his heart. To solve this thorny problem, we must rely on ourselves! ”He grabbed the vernier caliper and measured again. The densely packed red circles on the blueprint record countless failed attempts. When the first ray of morning light climbed up the windowsill, he finally found the broken thread on the umbrella, and a smile spread on his tired face. There are over 20 work notes soaked in the traces of time in the studio. Opening the yellowed paper, there are both the structural diagram of the new umbrella and the improvement plan repeatedly outlined with a pencil. Valuable experience is recorded and passed down by successive umbrella protectors. Before leaving, veteran Chen Jianguo solemnly handed over his long cherished toolbox to new recruit Zhao Lei. In the toolbox, old wrenches polished to a shiny finish carry countless memories of conversations with umbrellas. These old guys, I'll leave it to you from now on. ”Chen Jianguo patted Zhao Lei's shoulder, his eyes filled with reluctance and anticipation. Zhao Lei took the toolbox with both hands, carrying a heavy weight that was both a responsibility and a legacy. In the study room late at night, one can always see the figures of an old man and a young man. Chen Jianguo pointed to the blueprint and patiently explained the structural characteristics of the old umbrella, while Zhao Lei carefully recorded and raised his doubts about the new umbrella. From the material characteristics of umbrellas to maintenance techniques, from troubleshooting to innovative ideas, Chen Jianguo speaks without hesitation, and Zhao Lei also grows rapidly through repeated learning. A set of umbrella equipment embodies the youth and hard work of generations of umbrella protectors. Sergeant Ye Hancong's workspace was filled with experimental items of umbrella stacking devices. He was wearing goggles, holding a new folding mold, and his eyes were focused and firm. Repeated failures, repeated improvements... When he successfully folded the umbrella bag using the new mold, he jumped up in excitement. This little invention greatly improves the efficiency of umbrella folding. Li Jiyang, born in the 2000s, held thick professional books and shuttled between the study room and the umbrella repair room. From the aerodynamic principles of umbrellas to electronic control systems, he continuously gained knowledge and quickly grew into a capable assistant to the team. Old class leader Zhang Daoqing leads the team to delve deep into Ge
