Others show their swords, I show my missiles!

In the area of ​​Shenxian and Yanggu in the southwest of Liaocheng, the signalman's voice came through the radio waves, reporting the latest enemy situation detected by the drone with a hint of urgency:

"Report to Commander Li, drone reconnaissance shows that the Japanese 1st Independent Mixed Brigade has already moved!"

Upon hearing this, Li Yunlong raised his eyebrows, a sharp light flashed in his eyes, and he asked anxiously:

"Really? Which way?"

The signalman reported the enemy's movements quickly and in detail:

"The Japanese kept increasing their forces along the way. They set out from Xingtai and headed south. After reaching Handan, they split into two groups. One group advanced eastwards through Guantao and Guanxian, while the other group passed through Weixian and Daming and headed southeast. The total force was about 70,000 to 80,000. In addition, they were equipped with dozens of tanks that were much larger than Xiaodou. These tanks were heading in the direction of Weixian."

After listening to the signalman's report, Li Yunlong nodded slightly, with a sneer on his face:

"These bastards are finally willing to leave their den! They are just 70,000 or 80,000 beasts, yet they dare to be so arrogant. This time, I must smash their beautiful dreams!"

His tone was full of contempt for the enemy and firm belief in victory.

"Back then, our heavy armored combined regiment, with the strength of a single regiment, defeated the 200,000-strong enemy army and made them flee in panic.

Now, we have two columns in our hands, and the enemy is just a mob of 200,000 people, most of whom are puppet troops. Can't we defeat them? What a joke! "

Li Yunlong raised his eyebrows and a disdainful smile appeared on the corner of his mouth, as if the 200,000 enemy troops were just a group of lambs to be slaughtered in his eyes.

Zhao Gang, standing aside, suggested with a cautious look in his eyes: "Old Li, why don't we call together the commanders of the two columns to hold a meeting together, brainstorm and have a good discussion?"

When Li Yunlong heard this, he frowned, waved his hand, and shook his head without hesitation:

"What else is there to discuss? I can see through the Japs' little tricks at a glance. Two brigades will hold back the enemy in the direction of Liaocheng. As for the rest of the troops, we will catch them off guard. Once the Cheetah Armored 1st Column arrives, we will attack them from the front and back, encircle and annihilate them, and let them know how powerful Lord Ma is!"

His tone was firm and resolute; that confidence and dominance were Li Yunlong's unique style.

After saying that, Li Yunlong strode towards the door and pushed it open. Outside the door, the afterglow of the setting sun appeared hazy and dim in the sky full of sand and dust. The whole world was shrouded in a layer of gray and yellow, as if foreshadowing the coming night.

"It's getting dark, it's time for the Japs to find a place to hide."

Li Yunlong talked to himself, with a cunning light flashing in his eyes, as if he had already planned his actions for the evening.

"Tonight, our artillerymen must open their eyes wide and do a good job of calculating the accounts. In the first round of bombardment, we must let those Japanese tin cans see the power of our artillery. Before they know our details, we should give them some more 'welcome gifts'!"

There was a hint of ruthlessness and cunning in his words.

"Yes!" The signalman responded and left, while Li Yunlong stood at the door with his head held high, his eyes fixed on the gradually fading sunset in the sky. An indescribable sense of pride and ambition surged in his heart, as if victory was already in his grasp.

He thought to himself: "Another night has come. I have to toss around in this system space and see what new tricks I can come up with!"

In his system space, there are artificial intelligence-assisted design software, simulated wind tunnels, all-round robots, 3D printing and other high-tech gadgets. The most important thing is that the flow of time here is very different from that in the outside world. One night in the system space is equivalent to several years in the outside world.

However, the only drawback is that he is the only one in this system space, and it is extremely difficult to make any breakthrough progress in science.

It's okay to change the size and make improvements on the original basis, but if you ask him to develop a big thing like an aerospace fighter or an airborne aircraft carrier on his own, let alone one night, even if you give him ten nights, he will have to shake his head and smile bitterly.

"To encircle and annihilate the Japanese 1st Independent Mixed Brigade this time, the 1st Column of the Cheetah Army must quickly penetrate into position and clear the mines on the road as soon as possible." Li Yunlong thought to himself, "I still have to use this half night to modify the mine-clearing machine."

In fact, the mine-clearing drone in his hand had undergone two nights of modification and its performance had been greatly improved.

However, when encountering mines that cannot be detonated by microwaves and lasers, the only way now is to spray paint to mark them and then have a mine-clearing vehicle deal with them.

But tonight is a night operation and the spray paint is completely invisible, which worries Li Yunlong.

He also thought about using fluorescent paint, but then he thought that thing would be too conspicuous at night, and it would be troublesome if it attracted the enemy's artillery fire.

So he decided to add a new function to the drone, so that it can accurately locate the mines after discovering them, and then send the location information to the mine-clearing vehicle. In this way, the efficiency of mine clearance can be greatly improved.

The sun finally set. After Li Yunlong arranged the shelling plan for 3:07 a.m., he went straight into the warehouse of the temporary arsenal.

Before it was completely dark, he was already soundly asleep, and he even called it "getting enough rest to fight a good battle."

For the past ten days or so, Li Yunlong's bedroom has been located in the warehouse of the arsenal, and everyone has become accustomed to it.

In fact, he arranged Xiao Ai to watch the door, and he entered the system space early and started his research and development work.

Zhao Gang watched Li Yunlong walk into the warehouse, turned off the lights, shook his head helplessly, and thought to himself:

"Old Li, Old Li, your energy is declining day by day. It seems that you are really old. For the sake of our Commander Li's next generation, it seems that we have to find a companion for you.

The Anti-Japanese Army has sent a group of female nurses to support us. I have to go and see them when I have time. It doesn’t matter if they are too young to get married. I can just get to know them and cultivate some feelings for them first.”

It was 2:30 in the morning and the general attack was about to be launched. At Xiao Ai's reminder, Li Yunlong emerged from the system space with dark circles under his eyes.

A few hours in the outside world is equivalent to several years in the system space. Doesn't Li Yunlong have time to sleep?

At first, Li Yunlong's daily routine did follow the logic of ordinary people. He explored and researched the system space with all his might during the day, and at night he fell asleep like an ordinary person to recuperate.

However, as the research deepened, a subtle but fatal problem gradually surfaced - the fragility and forgetting of memory.

While concentrating on overcoming one technical difficulty after another, he sadly discovered that his memory of previous research results began to blur. Those modules that were once carefully designed now only left some vague shadows in his mind.

This discovery undoubtedly brought huge challenges to Li Yunlong's research progress.

In order to overcome this problem, he had to adjust his strategy and adopt a more direct and efficient approach: whenever he successfully researched a module, he would immediately start to transform it into a physical entity, rather than just leaving it at the theoretical level.

This change greatly promoted the progress of the project and brought new vitality to the originally stagnant situation.

However, the good times did not last long, and new problems ensued.

As the research deepened, the previously manufactured parts gradually revealed their shortcomings in subsequent applications and needed to be redesigned and reworked.

This is undoubtedly another race against time, testing Li Yunlong's wisdom and perseverance.

What was even more urgent was that this night was different from the usual nights, time was particularly precious, and only half a night was available. The attack would be launched in the second half of the night.

Facing the upcoming general offensive, Li Yunlong knew that time was running out, so he resolutely adopted a more extreme work system - the 617 work system.

At six o'clock every morning in the system space, when the first ray of sunlight had not yet completely dispelled the darkness of night, he had already begun his busy day; it was not until eleven o'clock in the evening that he reluctantly put down his work, hurriedly ate, and took a short rest.

Days like this happen seven days a week without a break.

It was with this extraordinary perseverance and persistence that Li Yunlong finally managed to produce the unmanned mine-clearing machine, a key equipment, before the system was released.
