While expanding, Xiao Yi didn't forget to strengthen the base's defenses. Xiao Yi knew full well that the base's development couldn't be separated from its solid security. He personally climbed the newly raised city wall and surveyed the surrounding terrain with a sharp gaze. The wind ruffled his clothes, and his expression was serious and focused. He summoned the fortification managers and military experts to the conference room for an in-depth discussion. "We can't rely solely on the existing city walls and watchtowers. We must establish a comprehensive, multi-layered defense system," Xiao Yi said in a firm and forceful voice. So, they began digging deeper and wider trenches around the base. The workers toiled day and night, their clothes drenched in sweat, but their tools never stopped. Xiao Yi frequently visited the construction site to check that the trenches met the required depth and width. New watchtowers sprang up like mushrooms after a rain, taller and more sturdy than before. Xiao Yi personally climbed to the top to test the performance of the observation equipment, ensuring it could detect any potential threats in advance. Strong checkpoints and defensive structures were added at the city gates. The massive iron gate was meticulously crafted, thick and sturdy. Xiao Yi meticulously checked the hinges and locks, looking for any possible loopholes. He also organized frequent military drills for his soldiers, simulating various possible attack scenarios. "We must remain vigilant at all times and not let our guard down even a little," Xiao Yi loudly encouraged the soldiers on the training ground. Meanwhile, intelligence gathering efforts were strengthened. Xiao Yi dispatched skilled scouts to gather intelligence in the surrounding areas, ensuring timely monitoring of enemy movements. Emergency evacuation routes and shelters were established within the base. Xiao Yi personally participated in its planning and construction, ensuring that residents could evacuate quickly and safely in the event of danger. At night, when everyone else was asleep, Xiao Yi would still be in his office, studying defense strategies, the light illuminating his resolute face. He held a single belief in his heart: to make the base an impenetrable fortress, protecting everyone's hopes and future.

New watchtowers towered tall, the walls were reinforced and thickened, and advanced defensive weaponry was installed. At the edge of the base, the new towers stood like giants. Constructed of sturdy wood and steel, they soared into the azure sky. Carefully painted in camouflage, the towers blended seamlessly into the surrounding landscape. Atop the towers was a spacious platform, surrounded by sturdy railings. From there, soldiers on duty, armed with high-powered binoculars, vigilantly observed every movement in the distance. The towers were equipped with elevators, allowing soldiers to quickly ascend and descend to respond to emergencies. The walls surrounding the base also underwent a complete transformation. The original wall was demolished, replaced by a taller, thicker new one. Massive stones and heavy bricks were tightly stacked, with high-strength concrete poured between them, making it indestructible. Sharpened barbed wire covered the top of the wall to prevent enemy climbing. Advanced defensive weaponry was securely installed at key points along the wall. Powerful artillery pieces aimed in all directions, their barrels gleaming with a cold metallic sheen. Automatic machine guns were nestled in bunkers, ready to unleash a deadly fire. New missile launchers waited patiently for their moment of activation. The technicians responsible for installing these weapons meticulously debugged and calibrated them. They meticulously inspected every component, ensuring they could unleash maximum power when needed. Soldiers stood by, diligently learning how to operate them and familiarizing themselves with their weapons' capabilities. Sunlight shone on these defensive structures, radiating a reassuring glow. They were more than just cold weapons and structures; they served as a safety net for the base's residents, symbolizing their resolve and strength to defend their homeland.

"We can't let the enemy take advantage again. We must ensure the absolute safety of this base," Xiao Yi solemnly addressed the personnel in charge of the defense. Standing in the command post of the fortification, his eyes sharp as an eagle's, he fixed his gaze on each person in charge of the defense. His voice was deep and powerful, as if every word weighed a thousand pounds. "This war has cost us a heavy price. We can't repeat the same mistakes." Xiao Yi placed his hands on the table, leaning forward slightly. "The enemy is cunning, constantly seeking our weaknesses. But we can't give them even a single chance. Do you understand?" His gaze darted from one person to another, and those caught in his gaze sensed the seriousness and expectation in his gaze, and they straightened their backs. "Every post, every detail, is crucial to the survival of this base. Soldiers in the watchtowers can't afford even a second of negligence; those patrolling the perimeter walls must maintain high alert; and those operating defensive weapons must be so skilled they can fire accurately with their eyes closed." Xiao Yi's voice echoed throughout the room. "I know this is difficult, and it will require tremendous effort and sacrifice on your part. But we have no way out. Every single person in the base, the elderly, children, and women, their lives depend on us." Xiao Yi took a deep breath. "We shoulder responsibility, hope, and the future of countless people." "So, I emphasize again that we must ensure the absolute safety of the base. Any mistake will be unforgivable." Xiao Yi stood up straight, his expression resolute, as if he was ready to fight the enemy to the death. The faces of the personnel responsible for the defense were solemn, and they responded in unison: "Yes, we will ensure the completion of the mission!" The voice was loud and resolute, and it echoed for a long time in the command post.

After a period of hard work, the base's expansion has yielded remarkable results. The once somewhat cramped site has undergone a dramatic transformation. Looking out, the new buildings are neatly arranged, presenting a scene of prosperity. The new residential area is spacious and bright, with brand-new houses neatly arranged. The houses are both beautifully designed and functional, with ample light and ventilation in every unit. The community is shaded by trees, and the roads are wide and clean. Children play in the garden, while elderly people relax on benches, basking in the sun, their faces beaming with joy. The factory area has expanded several times in size, with modern buildings rising from the ground. Advanced production equipment operates efficiently, humming with energy. Workers busily work on the assembly line, producing high-quality products that are shipped to various locations. The factory's output has increased significantly, not only meeting the base's internal needs but also exporting them, generating substantial economic benefits for the base. The farmland has also been greatly expanded, and crops are growing abundantly in the vast fields. Golden waves of wheat billow in the wind, and heavy rice ears bend the branches. Farmers toil diligently, their joy at the harvest overflowing with words. New irrigation systems and agricultural technologies have significantly increased farmland yields, providing ample food security for the base. The base's infrastructure has also been improved. Newly constructed roads are wide and smooth, making transportation more convenient. New water and electricity facilities provide a stable supply, meeting people's daily needs and production needs. Schools, hospitals, shopping malls, and other public services are readily available, providing great convenience for people. Regarding defense, sturdy walls stand tall, soldiers in watchtowers remain vigilant, and advanced defensive weapons are ready for action. The entire base resembles an impenetrable fortress, giving people a sense of security. All these remarkable achievements are the result of everyone's hard work and wisdom. Gazing upon the newly renovated base, everyone feels filled with pride and a bright vision for the future.
