Others show their swords, I show my missiles!

After about twenty minutes of silence, a deafening roar suddenly tore through the sky. The sound was like the wrath of Thundergod, penetrating the thick soil and striking people's hearts.

The already tense atmosphere in the underground fortifications was instantly broken by this sudden shock. Parts of the fragile wall could not bear the weight and peeled off, turning into fine dust, which slowly drifted away under the dim light, adding a bit of depression and uneasiness to this enclosed space.

Omanrek's heavy bomb landed on our army's position without any warning.

Fortunately, the enemy did not use the more deadly bunker-buster bombs, otherwise, this sturdy underground fortress would probably not be able to withstand their edge. Li Yunlong and Zhao Gang, the comrades who fought side by side, might really face the cruel fate of life and death.

Even so, the power of ordinary aerial bombs alone was enough to frighten the new recruits who had just entered the battlefield. There was anxiety and trembling in their eyes, and their bodies were involuntarily tense, as if even the dust in the air was telling of the cruelty and ruthlessness of war.

At this critical moment, Zhao Gang's figure was like a warm spring breeze, shuttling through every corner of the fortifications.

His steps were firm and powerful, and his eyes revealed unquestionable determination and encouragement.

His words were gentle yet powerful, nourishing the soldiers' dry hearts like spring rain, helping them dispel their fear and regain their confidence.

Zhao Gang comforted each soldier one by one in his own unique way. His voice echoed in the small space, becoming an invisible force that brought everyone together.

In the interweaving of comfort and encouragement, Zhao Gang demonstrated his ability of ideological education.

New recruit Xiao Li held his gun tightly, his face pale, his eyes revealing anxiety and fear. Zhao Gang stood beside him, his eyes firm and warm.

"Don't be afraid, Xiao Li. Our fortifications are very strong. We are now in the core part of the underground fortifications, which is enough to block those big guys outside."

"Political Commissar, this is my first time on the battlefield. Hearing those bombs falling, my heart felt like it was being pressed down by a huge rock. I couldn't breathe."

Zhao Gang patted Xiao Li on the shoulder and smiled with understanding: "When I fought my first battle, I was just like you. I was so scared, as if I was standing on the edge of a cliff and was about to fall off if the wind blew."

"Commissar, you too...?"

Zhao Gang nodded, his eyes deep: "Yes, I was just a young boy at that time, just like you, full of passion but also full of fear.

I remember that day, there was continuous artillery fire and bullets were raining down like raindrops. I was hiding in the trench, my heart was pounding.

But at this moment, I saw the comrades around me. Some of them insisted on fighting even though they were injured, and some rushed forward bravely without even blinking.

At that moment, I realized that fear is not our enemy, but escape is.

We stand here not for ourselves, but for our families behind us and for the peace of this land."

"Commissar, what happened next?"

"Then I took a deep breath and told myself I couldn't let fear control me.

I picked up my gun and rushed out with my comrades.

At that moment, I realized that I was much braver than I thought. Since then, I have told myself that no matter what I face, I must not let fear take over. "

"Commissar, I understand. I cannot let fear defeat me. I must face this bravely like you and my comrades."

Zhao Gang nodded with satisfaction and patted Xiao Li on the back: "That's right, Xiao Li.

Remember, there is a power in each of us, and that is courage.

As long as we are united in heart and shoulder to shoulder, nothing can defeat us. Now, take a deep breath, relax, and we will wait for the moment of victory together. "

As Zhao Gang finished speaking, the atmosphere in the underground fortifications seemed to become a little more relaxed.

Xiao Li's clenched fists gradually loosened, and his eyes showed more determination and courage.

The roar of enemy planes continued, and the ground was still shaking. But in this solid underground fortification, the soldiers' hearts became stronger because of each other's support and faith.

A chandelier could not withstand the shock of the bomb explosion and suddenly fell to the ground and broke into pieces. Several soldiers reflexively raised their guns and aimed at the debris on the ground.

Zhao Gang took a look and calmly ordered, "Turn off a few lights and unnecessary equipment to reduce electricity consumption."

Soon, Omanrek's three frantic bombers dropped their bombs, flapped their wings and flew away.

Immediately afterwards, the Japanese and the Yellow Shoe Army on the ground launched another attack, but were repelled by our army's remaining unmanned sniper units and the soldiers who returned to the bunker.

This wave of bombing cost Omanrek 3 bombers and 13 fighter planes, and our three bunkers were reduced to ruins.

A shallow underground working collapsed.

Although the artillery fire had not stopped, the soldiers in the underground fortifications breathed a sigh of relief and wiped the sweat off their faces.

A staff officer hurried into the command room, interrupting Zhao Gang's thoughts.

Zhao Gang's brows unconsciously furrowed. Looking at the solemn expression of the staff officer, he had a bad feeling in his heart.

"Commissar, the situation is not good." The staff officer's voice was low and urgent, "The Japanese have dug more than 200 meters, and there are only more than 500 meters left to the front of our position."

Upon hearing this, Zhao Gang immediately realized the seriousness of the situation.

He was just about to use the aiming device of the unmanned sniper unit to more clearly observe the situation outside, but at this moment, a heavy artillery shell suddenly fell on top of the bunker.

The violent vibration caused the chandelier to shake again, dust flew everywhere, and the entire bunker seemed to be shrouded in a thick layer of gray fog.

The image on the display was also affected, and there was a violent shaking that made people dizzy.

After the shaking stopped, the image became blurry and difficult to recognize.

Zhao Gang suppressed his discomfort and gently brushed off the dust on his clothes. His eyes remained calm and deep.

He asked in a deep voice: "How many sniper units are left that can observe the excavation area?

The staff officer shook his head helplessly: "Just now there were two left, but now... I'm afraid there is only one left at most."

His words revealed deep worry and helplessness.

Zhao Gang and several staff officers hurried to the display screen of the last unmanned sniper unit.

Fortunately, the observation and aiming system of this unmanned sniper unit survived.

Everyone stared at the screen with bated breath, feeling uneasy, as if every second of waiting was a great test of their will.

As the sighting system slowly turned, a shocking picture suddenly came into view - the enemy's position had now become a sea of ​​fire, with explosions and wailing intertwined. Through the blazing flames, one could vaguely see the devastated land engulfed by smoke and flames.

"Look! The Japs are running away!" a staff officer exclaimed, pointing at the screen.

In the light of the fire, the surviving enemies were fleeing in panic. Their figures looked particularly embarrassed and helpless in the smoke and fire.

"It must be Lao Li!" Zhao Gang's voice was full of affirmation and gratitude, "He must have seen our predicament, so he called in artillery support!"

The truth is more complicated and ingenious than Zhao Gang imagined.

It turned out that after receiving the photo of the unscrupulous artillery sent by Zhao Gang, Lao Li keenly sensed the crisis on the front line.

Li Yunlong knew Zhao Gang's characteristics. He would not ask for help from him unless it was absolutely necessary.

He did not choose to directly order the Second Artillery Regiment to provide artillery support, but instead adopted a more covert and efficient action plan.

At this time, the Second Artillery Regiment was fully supporting the battle in the direction of the Beast-Exterminating Valley and had no time to care about Zhao Gang.

So Li Yunlong quickly took out six heavy drones and a set of catapult devices from the system space. These high-tech weapons are not only highly concealed, but also accurate and powerful.

This is an upgraded version of a drone whose main purpose is bombing. It has a bomb load capacity of 10 tons, but does not require a runway to take off.

Because it is a drone, it can be launched by catapult with the greatest possible acceleration, without having to consider whether the crew can withstand such a large overload.

The disadvantage is that it is a bit troublesome to recover: because it is far larger than the original size and is newly developed, the runway originally used to recover drones is no longer capable of it.

Therefore, when recovering, you need to throw away the remaining ammunition, use up all the fuel, lower the altitude, slow down the speed, aim at sparsely populated areas, and then leave it to fate.

Of course, if there is time and sufficient machinery and equipment, it would only take two days to build a barely adequate runway.

This is a type of unmanned bomber that Li Yunlong researched and modified himself using drones and various materials exchanged from the system, as well as various machines and equipment that had already been exchanged in the system space.

Li Yunlong has undergone system knowledge reinforcement. If he does not make use of this knowledge, all the system's efforts will be in vain.

While transforming this type of drone, Li Yunlong was surprised to find that the system space seemed to be a secret realm independent of the external time flow.

Here, the flow of time is completely different from that in the outside world, but it is difficult to say which one is faster or slower.

He was surprised to find that the long days and nights he spent in the system seemed to be still to the outside world.

After several hours of contemplation, the outside world has not changed for a second; after three to five days of intensive research, the outside world still remains the same as when you first saw it; even after living in the system for two consecutive months, the outside world has only quietly passed by for a short five minutes.

And during this long "internal time", as long as he left the system space, his beard had not grown, the burden on his bladder had not increased, and all physiological activities seemed to be running according to external time.

However, he also has to eat and sleep every day in the system space; his heart rate in the system space is also about once per second as in the internal space, instead of being calculated according to the external space.

If calculated based on the speed of time flow in external space, his heart should beat once every 48 hours within the system.

However, this strange system space presents a different picture of the laws of nature.

Crops sown in the system space thrive at an astonishing rate, and time is accelerated here;

The period from hatching to egg laying for laying hens is compressed to a little more than half an hour in the outside world.

This allowed Li Yunlong to taste the sweetness of the time difference for the first time, but because he had not adapted to it yet, he regrettably witnessed the tragedy of several caged chickens dying of starvation due to the time mismatch.

What is even more bizarre is that the physiological time of the living animals and plants exchanged through the system - live pigs, live chickens, etc. - stubbornly follows the rules of the outside world.

Even if they briefly travel between the two time dimensions, these creatures seem to carry some kind of "time mark" and grow firmly according to the pace of external time.

In order to transform these drones, Li Yunlong stayed in the system space for fifteen years!

Fifteen years is just less than one night to the outside world, but within the system space, these long years have witnessed Li Yunlong's sweat and persistence, and also allowed him to reach an unprecedented level in the transformation of drones.

Not only did he overcome numerous technical difficulties, but he also explored the subtle and complex connection between life, space and system time in the mist of time.

At present, Li Yunlong has modified seven aircraft. One of them was taken out by Minister Yang and placed in a highly confidential laboratory. A group of top military scientific research personnel are conducting more in-depth analysis and optimization on it, striving to tap its potential to the fullest.

Li Yunlong took out the remaining six aircraft all at once, disassembled them into modules, and handed them over to the transport team along with the catapult systems and sent them to the air defense regiment.

That's right, he gave these planes to the Air Defense Regiment instead of the Air Force 1st Regiment.

Because he knew that the 1st Air Regiment was busy fighting in the northeast and had no time to look south, he handed over the batch of drones to the commander of the Air Defense Regiment, Xiao Zhanwu.

As one of Li Yunlong's first missile disciples, Xiao Zhanwu is a leader in the field of drone warfare and has profound attainments in missile strike technology using drones.

In fact, Xiao Zhanwu did not let this trust down.
