The war began to catch everyone off guard. However, although the artillery soldiers were not experienced many battles, they were well-trained. The repeated training made their artillery bombardment quickly suppress the enemy's first wave of attacks, like conditioned reflexes. It also suppressed the most dangerous assault.

This is the enemy's closest assault to the city wall. If the enemy touches the city wall, within 500m, the effect of these direct firepower can be greatly reduced. At the speed of those masters, this distance can quickly rush to the city. Compared with the power of these direct fire cannons, heavy machine guns are slightly less powerful to the strong people in this world. Basically, only by lowering the anti-aircraft guns for air defense can they effectively kill those with more than three revolutions.

At this moment, the bombing of artillery fire brought severe chaos to the enemy. But at the same time, the bombing of artillery fire also had defects. The explosion of artillery created a large amount of smoke. Not all observers could see the enemy clearly through the smoke. Their reconnaissance killing moves would also be affected by the storm released by the artillery, especially the huge sound waves caused by the explosion of artillery shells will affect the effect of echo positioning and interfere with the judgment ability of these reconnaissance players.

At the same time, the inside of the enemy responsible for the attack also slightly recovered from the initial chaos.

They each held walkie-talkies and called each other in a mess in my heart, because they were not familiar with how to use this thing in their hands? Most people were concentrated in the same channel, which caused the internal noise to be very noisy. Whoever had a loud voice and who could get the right to speak.

This thing was given to them by Dongfang Yuliang, and it is said that it cost a lot of money. It was made from the immortal behind the scenes. It is said that a huge empire was established from the distant southern Xinjiang, which was a commodity exported by that empire. According to the description of the goods, this thing can maintain communication within a range of more than ten kilometers, and has an immediate effect on the chaotic battlefield. Dongfang Yuliang saw the cross-age meaning of this thing, so he spared no expense. He asked for this thing from the immortal behind him.

The battle between the royal court in Beiyuan is actually very similar to the battle of the gods. It seems that a group of mortals are fighting, but in fact they are the immortals behind the mortals. In the big game, the mortals on the battlefield are just chess pieces. This means that if they fall into a loss on their side, they can ask the immortals behind them to help. Fang Yuan, the original history, participated in the battle between the royal court, and took the opportunity to blackmail the benefits. He blackmailed a large number of wolves from the immortals behind the scenes of the Hei Family, and even many wolf kings with the strength of the fourth-level wolf kings. These things can only be regarded as residues in the cracks of their fingers for immortals. But for mortals in the chess game, they are already a force that can determine the outcome.

The communication device worn on these commandos at this moment has indeed worked. Dongfang Yuliang considered that these untrained people would definitely not be able to use this communication device well. Therefore, he gave the captain he selected to ban the entire channel of the ban. When he needed to speak, he could ban the others.

At this moment, there was chaos in the channel, and the effect of this command was reflected. The commander directly banned everyone and shouted in the channel: "All people who can fly take off, and those who can't fly lie on the ground without moving. The grass is dense. As long as it doesn't move, it will be difficult for the enemy to discover us.

Don’t be afraid of those who fly into the sky. Only when the enemy’s shells explode on the ground can they kill us on a large scale. The space in the air is much wider than that on the ground, and they cannot hit it accurately.”

In the channel, because the forbidden speech suddenly became quiet, only this voice was left. Although many people did not know who made this voice, the instinct in panic still made them subconsciously follow what the backbone could stand up to. In a moment, everyone flew into the sky one by one.

Those who could not fly were lying down on the ground and hid in the grass. This move was indeed effective in hiding some people who were hidden in the grass and were killed by one shot after a slower pace. However, more of them did escape the scanning of the searchlight. They successfully escaped under the cover of smoke and dust caused by artillery fire, but I don’t know when they can escape in the chaos.

Those who flew into the sky were still being tracked by searchlights, but as people said before, how vast is the sky, where can the searchlights keep up with them?

Searchlights shine on the ground. Because the reflection of objects on the ground can illuminate a large area. However, in the sky, searchlights can only illuminate a cylindrical area. Unless they are just shrouded in this cylindrical area, it is quite safe to fly in the sky, especially in the night, and it is even more difficult to find their existence.

At this time, the city defense cannons also turned to the air to fire. The limited technology made them unable to recognize the enemy's near-explosion fuse. The Gu Master is not an aircraft and does not have many metal parts on it. It is still a bit difficult to rely on electromagnetic induction and Doppler effects to make the shells explode when they flew past the enemy's position.

If these shells do not explode, the killing efficiency in the air is absolutely low. If the trajectory of the shells flying alone wants to penetrate the enemy, then it is purely a struggle for luck. At this distance, it is still dark. The only possibility that can block the enemy is to use shells to lay barrage in the air and build a fire isolation belt in the air. As long as you try to pass through this barrier, you will be treated with fierce firepower.

The shells were installed with a delay fuse and would explode after flying to a certain height in the air. The fragments brought by the explosion were the main source of damage. The shells in the sky exploded one by one like fireworks. A large number of prefabricated fragments were released, forming a death storm area in the sky.

The commando team members who had always despised the shells before and thought that they could not hit their heads when they arrived in the sky hit them. They immediately hit their heads and bloodied. Several unlucky ones were directly penetrated by prefabricated fragments. They lost their ability to fly and fell from a height of hundreds of meters.

There was no need to rescue him when he hit the ground. He had already fallen and had no human form. With this stupid method, many experts who were good at flying were blocked.

However, to be honest, this move is just a stopgap, because this defense method has one of the biggest flaws. It is that it consumes too much ammunition. The underground base is not a Republic of Mountains and Rivers, and the productivity has not yet expanded to that point. The production of shells is also cost-effective, especially the powdered Gorery potato pot filled inside the shells. Even if you buy the mother pot, which has been improved many times in the Republic of Mountains and Rivers, the output of explosives produced is still limited and cannot be used openly.

Such defenses will only last for a few hours at most and will exhaust the ammunition. Even if the enemy attacks the city wall head-on, they will probably be unable to resist if they lack ammunition.

The commander selected by Yu Liang from Dongfang is obviously also a good at adapting to the randomness. Although he will not rush to the front line of the battlefield, he will carefully observe how other soldiers fell on the battlefield. He will adjust his deployment in a targeted manner. The communication channel will send instructions again, requiring soldiers who are already a little red-eyed to stop attacking.

"All flying soldiers stop attacking and circle around the enemy's fire defense zone. Look for firepower weaknesses, and once they are found, they will attack tentatively. It doesn't matter if they can't find it, continue to circle. I don't believe that their ammunition is infinite." On the battlefield of this era, they have surpassed more than half of the generals. Being able to think about the point is even more rare and excellent generals.

A large number of soldiers hovered in the air and hovered on the periphery of the fire storm. It did put a lot of pressure on the air defense soldiers at the underground base.

If their technology is more advanced, they actually have a way to deal with this tactic. Just use missiles to launch, and as long as they rely on guidance, they hit enemies who flexibly avoid them in the air. However, today's technology production chips are almost impossible. Let alone production missiles.

They were obviously very clear about their shortcomings, so after the enemy retreated from the fire blockade circle, they did not try to use missiles to attack. Instead, several special shells were knocked to high altitudes.

The anti-aircraft guns that fired these shells were adjusted to an exaggerated angle. The shells flew all the way to a height of thousands of meters. Then the parachute was opened in the air.

Immediately after another sun rose in the air. The shells hanging under the parachute burst out with an extremely bright light. They continued to illuminate the sky and brightened the battlefield. This immediately exposed the enemy's position. Originally, they were hovering in the air, and it was difficult for anyone to discover them. But at this moment, the flares here were illuminated like daytime. The hidden effect of the night was completely useless.

As these people were shining out, anti-aircraft machine guns began to aim at these people. Shooters were not good at shooting such distant targets. The settings on the sight were actually not very useful. At this time, tracer bullets were used to indicate the ballistic trajectory of the weapon. Then manually adjust the trajectory of the weapon and splashed water on the enemies running around in the sky.

The hit rate of water splashing like this is worrying. It is also difficult to cause any fatal damage to enemies at this level. But one thing is that if the attack hits the wings, it is quite likely to knock people down from the sky. Even if you are prepared, you will not fall to the ground and cause serious injury. After falling to the ground, you may be named by heavy artillery. Therefore, this kind of water splashing enemy has to hide.

So the impact of the high-speed attack towards the city wall was blocked partly by force, which saved a lot of shells and blocking lines.

However, such defense can only stop those enemies below the fourth turn. When it reaches the fourth turn level, its combat power is equivalent to the level of the head of each family. Although there are not many such masters, there are more than a dozen of them in the commando team. At this moment, relying on the strength of their bodies, they directly ignored the shrapnel, broke through the blockade line, and landed on the city wall.

Originally, they were just going to set fire in the city, but now it seems that they will not tear a hole in the defense of the city wall to attract the attention of their opponents. It is difficult for those tribe members who are not strong to evacuate safely.

And their fierce attack did have an effect, and the attacked wall suddenly became silent. Ma Hongyun watched a piece of artillery squad beside him buried under the broken wall, and he was unaware of life and death. Before he could react, he was pulled off the wall by someone. He was a battlefield mechanic and was not responsible for facing the enemy head-on. The logistics personnel evacuated as soon as possible when facing the enemy's attack. He was originally going to restrain his opponent, but he was dragged back by his own people.

After falling on the city wall, these masters merged into the unmanned realm. Their powerful killer moves are comparable to human-shaped missiles. After the distance is closer, these people can quickly eliminate targets that threaten them.

A four-turn master had a steely color all over his body. The bullets of the heavy machine gun hit him, sputtering sparks, but they could not break his defense at all.

Instead, he picked up a piece of scrap iron and threw it over, and directly smashed it out with the man and the machine gun.

The desperate gunner on the position flattened the cannon, completely contrary to the requirements of training, and shot flat on the city wall at the enemy. This distance was not enough to use the cannon to mirror, and it was impossible to hit the wrong shot with the naked eye.

With a bang, the enemy covered in iron gray disappeared in an instant and was knocked away by shells, smashing a city tower. But what made people desperate was that in the collapsed city tower, the four-turn master with clothes turned into cloth strips, lifted the collapsed city wall and climbed up again without any injuries.

If this scene made the gunner desperate. Even the artillery in his hand could not hurt the enemy, what hope would they have?

Ma Hongyun was anxious when he saw this scene and wanted to go up and help, but he was not sure about his strength in his heart. Logically, he absorbed the essence of a Ten Thousand Beast King. It was indeed very strong. But the Ten Thousand Beast King was only a four-turn strongman, which was on the same level as the man just now. He lacked combat experience and might have to send him off.

Just as he was struggling, heavy footsteps sounded from the city, and tons of heavy objects trampled on the ground and ran towards the city wall quickly. He saw his old friend running while wearing a heavy steel helmet on his head, dragging the heavy power armor, and rushing to the top of the city.

The four-turn master with iron gray all over was walking towards the desperate gunner slowly, ready to appreciate the scene of her twisted neck, but felt a huge force coming from beside him, and the heavy chain saw sword hit him like a heavy hammer...
