Chapter 2143 Fighting like conditioned reflex

The outbreak of war is often very sudden. Ma Hongyun was on duty on the city wall that day, and the underground base now has a circle of outer walls, which was built after the last attack. The composite wall is stronger than simple reinforced concrete. The structure similar to carbon fiber makes most physical attacks unable to break through the thick city wall. Although the city wall is not a shield, it can still be crossed if it can fly. But the flying people are in the minority. Without flying insects, even the five-turn strong people may not be able to fly.

The partitions formed by the city walls can cover a large number of weapons. Many weapons are buried inside the city walls, like armed tanks, relying on the thick outer shell to almost be immune to all attacks.

With such a city wall, it can at least bring a great sense of security to the people in the underground base from a psychological level. Ma Hongyun patrolled the city wall. The main purpose was not to patrol whether there was an enemy invasion. He was not a scout. He did not have relevant reconnaissance skills. The probability of discovering the enemy was actually very small. His patrol was mainly to check whether the turret was normal and to check whether the machinery on the city wall was normal.

He carried more wrenches, not firearms, and knocked on the pipes, and judged whether the pipes were normal through the echo of the sound.

This kind of thing that old workers can do through experience, now through the construction of killer moves, new mechanics can do it. Light bars appear in Ma Hongyun's pupils, showing sounds of different frequencies, and the shape of the light bars meets a certain threshold. This means that the pipeline is operating normally.

The facilities on the city wall are quite new, so I didn’t find any mechanical failures after patrolling the next round. I just routinely maintained the steam pipeline to provide painting and maintenance where there was long-term steam spraying.

If it is normal, after patrol for a while, he should go back. But before he went back this time, he happened to meet the sentry who was replaced. A pair of telescopes were hung on the sentry's chest. High-precision optical glass is rare in daily life. Such a telescope is definitely a rare thing. Ma Hongyun, who was so stupid, talked to the sentry who had changed his post. The sentry on the post cannot talk to them casually, otherwise it is very likely that they will be shot directly. But they are just ordinary people who have changed their posts.

When a person saw someone talking to him, he stopped and heard that the other party was to use his telescope to take a look. After thinking for a while, he nodded. He was not worried that the spy was preparing to take this opportunity to tamper with his telescope. According to the regulations, every time he changed the job and returned to the dormitory, he had to check his telescope. It was confirmed that the parameters on it were normal. Now even if ordinary people touched it, they would be discovered after any small movements made by them.

Ma Hongyun is indeed not a spy, he is just curious. After all, telescopes of this type are not common. He really doesn't have much chance to play with them on weekdays.

After I really got started, I suddenly felt novel. Look at this and that. Then I was a little disappointed. The optical telescope had a very poor capture effect on weaker places. I could see the brightly lit industrial area very clearly. I could even see the safety helmets above the workers' heads on the construction site. I couldn't see clearly from the dark wasteland outside. Only the searchlights could vaguely see it. The endless grassland was like a vast ocean in the night. It was extremely deep, giving people a feeling of not seeing the end, like falling into an abyss.

He stared at the grassland for a while. There was basically no sight of anything without the searchlight. But as he concentrated, he did not notice that his pupils began to spread. His pupils quickly became bigger, like a cat, and their pupils expanded to almost the same as his pupils. The huge amount of light entering allowed him to finally see clearly what was hidden in the darkness in the distance.

He had not had this ability to adjust the amount of light entering his pupils before. It was the ability to wake up after observing the darkness through a telescope this time that the Taoist traces on his body woke up to help him awaken.

On the distant plain, he vaguely saw black shadows moving forward on the grass, lined up in twists and turns, and surrounded the city slowly.

This scene scared him. At first he thought it was an illusion. But soon he realized that his power was probably different from others in the darkness. The darkness would cover him, but would not hinder his perception.

So much so that he was not discovered, but also sensed that the enemy was constantly gathering troops at a very distant distance. A reconnaissance plane had aerial photos of the enemy's traces. At that time, the enemy was still quite far away from the underground base. These people were besieging the underground base from different directions. The strategic purpose was already obvious on the aerial map, which was to occupy the area where the underground base was located.

However, if you estimate based on the contents of the aerial photography, it will take at least three days for them to arrive at the area where the underground base is located. Therefore, the underground base is also based on the preparations made in the face of the general attack in three days.

But I didn't expect that the enemy was discovered under the city wall today. Judging from the ruler on the telescope, it was probably only a little more than 1km away from the city project.

If it weren't for being so close, it would be difficult to spot them even with telescopes. These people seemed to know the rules of searchlight patrols, and they paused for a while every time they advanced, just avoiding the scanning of the searchlight, so that they had already reached such a close position and were not discovered.

Ma Hongyun saw this scene and his hair stood up, but he still cautiously doubted whether he had read it wrong. He stared carefully at the place where the enemy had sneaked in for a long time.

At this moment, the elite soldiers lurking were all holding peach pits in their mouths, ensuring that they would not make any sound. But although they could not talk to each other, they still admired Dongfang Yuliang, who had made this plan in their hearts.

"It should be said that he is worthy of being the wisest man in Beiyuan. He has so many opponents. The big iron bird flying in the sky has long seen our movements clearly. If he really launched an attack at the speed of the march, even if he could win in the end, he would probably suffer heavy losses.

But the military has slowed down our marching speed. The birds in the sky have indeed misjudged the date of the arrival of the army.

Now our small army is the sword that breaks through the enemy's defense line. It has sneaked into this position and has not been discovered yet. It seems that victory is in sight. As long as we continue to lean forward, we can directly attack the city wall. We set fire in the city while the chaos is happening. As long as the scene becomes chaotic, even if our mission is extremely risky, the probability of survival is still very high."

Many people in the team had the same idea. Their commanders were really perfect. They not only misled the air force at the underground base through the false speed of the army, but also calculated the patrol rules of the searchlights at night. Through the calculated rules, the infiltrating troops successfully arrived near the city wall without being exposed.

But just when they felt that victory was in sight, Ma Hongyun was finally sure that he had read it correctly and quickly handed the telescope to the non-commissioned officer: "Sir, I just saw an enemy approaching our city wall. According to the ruler, they were probably only more than 800 meters away from the city wall."

The sentry on duty who had just replaced him suddenly turned serious when he heard this: "You can't say this nonsense. Where did you see the enemy? Point me a general direction."

According to the direction pointed out by Ma Hongyun, the sentry quickly observed the area through the telescope. But it was blurry in the sentry's field of view, with only the traces of the wind blowing the grass leaves, and the figures on the ground could not be seen clearly. In such a dark environment, he even looked at the grassland, let alone the people hiding in the sesame size.

"Don't you see them yet? I can see their location. If you don't believe it, please mobilize a searchlight for directional illumination. I can tell their location. As long as the searchlight illuminates them, we will naturally be sure."

The sentry nodded when he thought of this. Although he had just changed his duty, he still regarded protecting the underground base as his duty and had the authority to mobilize the searchlights.

As a searchlight changes its rotational pattern, it shines in a direction that should not have been illuminated.

Suddenly, dense figures of people appeared in the telescope's observation.

The elite soldiers who were infiltrating suddenly were shrouded in the light of the searchlight and stood up one by one. A few even escaped in panic. But more eyes showed cruelty. They had reached this distance. Even if they were exposed, it was worth a rush.

The next moment, a rapid alarm sounded. Under normal circumstances, even if the searchlight shines on a person, sentries may not recognize it as a person at the first time, but at this moment someone is staring at that area. The searchlight just swept over and the army hidden inside is exposed.

While the emergency alarm sounded, compared with the soldiers stationed on the city wall, the cannons inside the city wall opened fire first.

The artillery inside the city walls were also garrisoned by soldiers. The ones responsible for this side of the artillery were soldiers of the Seventh Artillery Battalion of the Second Army. They had just been on duty. In order to ensure that they were not sleepy while on night shifts, the battalion commander allowed them to chat during the duty. In addition to the few people guarding the orders on shifts, others were even allowed to play cards to relieve boredom, but one thing must be guaranteed, that is, the artillery must be in a state of preparation and excitement at any time.

This is a city fire artillery, not a long-range gun. These are all used to set the muzzles of heavy artillery flat and direct fire, which means that their targets will usually be within three thousand meters.

At this distance, you must achieve a quick battle. They practice targeting the target as soon as possible and firing at the first time. At night, the target of their fire is very clear, and they need to distinguish where the enemy is. Where the searchlight is shining, the searchlight at which position is trembling at high frequency or marked with special colors, they cover the firepower of the area.

I don’t know how many times I repeated the movements during the drill. I never used them once when I was on duty. So much so that they even doubted whether their practice was meaningful.

But they really came to the chaotic battlefield. The facts proved that the previous exercises were all meaningful. Without high-intensity exercises, they would not be able to react and adjust the gun parameters as soon as possible after the searchlight light turned red.

The moment the alarm sounded, the entire artillery battalion moved. In the panic, they didn't have time to think too much, thinking that the enemy had already hit the ground. After all, it was common sense that the range of their city defense artillery was limited. When it was their turn to shoot, the enemy might be very close to the city wall and was in an extremely dangerous state.

In a panic, the only thing that can help them is conditioned reflexes and muscle memory.

Everyone was like a part of the machine. They subconsciously did things they had trained countless times. When their brains could not think rationally, they pulled out the safety of the shell according to their instinct, closed the bobbin to aim at the red area, turned the muzzle, and put the gun on the right position, and then everyone stayed away from the cannon. The gunman pulled the long rope, and the violent roar and strong muzzle storm made the soldiers almost unstable, but they began to carry out the second round of filling in the conditioned reflex.

The soldiers on the city wall who are responsible for adjusting the position of the searchlight. At this time, they are also conditioned and reflected according to the situation reported by the detective's telescope. Adjust the direction of the searchlight and shine the red light at the position where the enemy is.

Although the enemy sent a small group of elite troops to infiltrate, the number was already quite large. At the same time, the siege was carried out from all directions, and no single breakthrough was chosen. Their purpose was to break into the city and set fire instead of destroying a section of the city wall.

Now some of the scouts in Zicheng are busy. While using Hawkeye to enhance their vision, electromagnetic perception and ultrasonic perception are also used at the same time. Through all-round senses, they are reconnaissance to find the enemy's location.

Under the all-round high-power electromagnetic radiation, the detected echoes finally exposed the enemy's direction.

The red beam of the searchlight is like the King of Hell being named.

Wherever the red light beam is shining, a violent explosion will occur. So much so that the elite gathered on the battlefield are scared by the red light. Most people have not even distinguished whether the attack comes from the light source or something else.

Several who were good at long-range attacks randomly released their attacks. They hit the searchlights at the city, and suddenly shattered several searchlights, but the artillery fire continued to cover them.

In this way, the underground base fired the first shot of the second Beiyuan anti-encirclement and suppression campaign in Beiyuan.
