Su Yun didn't feel a sudden sense of enlightenment, he saw layers of black walls less than a hundred meters away. www.biquge.info In fact, in this dense underground, any space that is too large can cause a collapse, so the space outside the passage is not huge and vast, but consists of countless fluffy cavities, and if you want to find a similar analogy, you can refer to the internal structure of cheese.

In such a place, there is no point in concealment. A neat formation of carrier-based aircraft poured out of the nest, and the searchlights carried on them were extremely powerful, and the staggered pillars of light illuminated the filthy air underground, revealing dense floating particles -- not dust, but countless spores implicated in the cocoon filaments, wriggling, waiting for something.

In the next second, the searchlight carrier-based aircraft began to detonate one after another.

This deflagration is an active attack, and as the vanguard of the storm, they have two tasks, one is to illuminate the battlefield ahead, and the other is to clear the spores of the enemy's forward positions.

They do not need to return home.

In an instant, brilliant fireworks exploded in the small space, and a total of 22 groups of about 100 carrier-based aircraft groups simply self-destructed, their bodies were filled with high-spirited incendiary bombs, and they attached to everything within the explosion range like a heavenly maiden scattered flowers. The bright white flame became the only color, and under the powerful light, Su Yun felt that the surroundings were extremely dark.

It took two minutes for the fire to dissipate, everything was purified, and the spores formed a suspended ball of fire, burning and falling. The thick layer of pollution covering the walls was still raging, and it looked like a world made of pure fire, and the oxygen index in the air was decreasing, and soon it reached a point where it could no longer support the burning of pollutants, and the light in the distance dimmed.

The burning sensation made Su Yun frown slightly, even if they were dozens of meters away, the temperature of the surrounding air was still extremely high, at least to the extent that they could fry eggs. But at the same time, on the rock walls covered in heavy pollutants, the combustible pollutants are burned and consumed, so as the flames are extinguished, what is hidden inside is gradually revealed.

A deep-sea fortress that is ready for battle.

A few decades ago, when the deep sea dared to build the main nest on an island deep in the ocean, these deep-sea fortresses were also called deep coastal defense fortresses, and now that humans have mastered air supremacy, watching everything on the surface of the sea from space, the deep-sea main nest retreats back to the bottom of the sea. However, the shore forts did not disappear, they evolved and became the backbone of the defense of the main nest, only in the core main nest group.

These deep-sea fortresses are incredibly powerful, not only with cannon capabilities comparable to the main guns of battleships, but also equipped with dense anti-aircraft equipment, they hide in the contaminants, waiting only to deliver a critical blow to the enemy. There are only a few deep-sea fortresses that have been revealed now, but in fact, Su Yun knows that this is just the tip of the iceberg, in the deeper depths of the pollution, there must be more deep-sea fortresses, which are aiming at this passage with long guns and short guns......

However, this is not the first time that the expeditionary force has penetrated into the main nest, and they have been prepared for it for a long time.

The second wave of offensives followed, and 22 groups of interceptors had already suspended at the mouth of the passage, covering the passage with a diameter of 100 meters in a neat and orderly manner, forming an array of 10 meters from top to bottom at the front and back.

It wasn't until half a minute after they were ready that the first deep-sea fortress erupted in flames.

The shells came in an instant, straight into the interceptor's defensive net.

The blow may seem devastating, but it is not. The interceptor was hovering, with a 10-meter gap in between, but it was negligent but not leaky. At the same time as sensing the artillery, one of the closest interceptors unfolded its reaction position, which was exactly 10 meters in diameter and could only exist for a moment, but the energy generated was extremely large, equivalent to a small-scale directional detonation in situ, and with accurate timing, it was just able to intercept the armor-piercing projectile launched by the deep sea fortress.

At the cost that the interceptor was also torn to shreds at the same time as the position unfolded.

It is disposable.

The shelling of the first deep-sea fortress was like a signal, and immediately after, more deep-sea fortresses began to act, and continuous artillery fire rang out one after another. The deep sea is a learning one, and although it is not flexible, it always finds the most efficient way - they do not fire blindly, but cover the passage mouth one after another at an uninterrupted speed, the interval between each cannon is exactly the duration of the interception position, and the landing point of the shell is strictly the same as the first shot, in order to break through the force field array under the interception and setting with the highest efficiency.

But these deep-sea fortresses can also only fire once.

Therefore......

At the same time, Su Yun also received the counterattack signal, and under the assignment of the central command system, he got his own shooting target, which was a deep-sea fortress located above the side, which had just exposed itself because of the fire, which was highlighted in the virtual reality system. Su Yun took aim instantly, and then fired a series of main guns with a roar.

Under the precise strike at close range, the fortress was instantly destroyed.

He was not the only one who received the order, and while the artillery was being fired in the deep sea, the artillery fire on the side of the expeditionary force was also sounding continuously. Unlike deep-sea shells, the expeditionary force's shells will also trigger a reactive force field when passing through the interceptor to ensure that the deep-sea main cannon will not take advantage of the weakness, but the shells fired from the inside to the outside will not only not be blocked by the position, but will be greatly accelerated in the detonation, thus generating several times the original power. Almost every deep-sea fortress that fires its main guns will be destroyed within 3 seconds.

On the other hand, the interceptors are constantly replenished, and in the interception array, it can be said that one side is destroyed and supported from all sides, and no matter how fierce the artillery cover of the deep-sea fortress is, none of them can break through the defense line. Of course, the interceptor is so stable and seamless, and its cost is quite expensive, almost the most expensive of all types of carrier-based aircraft.

Su Yun looked at the interceptors flying all over the sky, thinking that these were all shredded money......

The battle seemed to be over soon.

In just a few breaths, no less than 50 fortresses opened fire, and the sky was already full of fire outside the passage. But it was destined to be an unequal battle, and the fortresses had nothing but to destroy more than 50 interceptors, but the counterattack from the expeditionary force was ineffective, and under a single efficient fire, almost all the exposed fortresses were bombarded to smithereens.

The opposite side finally fell silent, but the interceptors did not disperse.

Because everyone knows that at least more than half of the fortresses on the deep-sea positions, which seem to have been reduced to ruins, have not been destroyed, they are hidden in the deeper depths, and they are not involved in the first round of shooting.

Well, a third wave of attacks is launched.

The overwhelming array of attack aircraft was released by 11 carriers, who did not form in formation, but were completely dispersed and passed evenly between each interceptor. At that time, the deep-sea fortress group that had been dumb once again erupted into a cannon sound that shook the world, but this time the artillery fire was not the previous large-caliber main gun, but the overwhelming small-caliber secondary artillery, which was also evenly covered in nearly 10 different coordinates, wanting to take advantage of the attack aircraft being sent out and the interceptor plane's weak defense to launch a devastating surprise attack on the entrance of the passage.

However, these attack planes were only decoys, and in the force field generated by the interceptors, the expeditionary force, which had long been ready to attack, once again devastated the remaining fortresses, and in another exchange of fire that lasted for several seconds, the two sides achieved completely unequal results. This time, it was finally quiet outside the passage, until the fourth wave of attack planes broke into the battlefield in large numbers, and there was no decent return fire in the deep sea.

The first contact of the expeditionary force with the deep sea, won with the advantage of completely occupying the initiative. (To be continued.) )
