Compared with the front pass, the back pass is more narrow and long. Long before the Kamon army marched in, He Yongnian sent engineering ships to push away some movable celestial bodies and establish an open field within the narrow pass, which people habitually called "fish maw".

A group of 5,000 battleships, three layers of staggered arrangement in the "fish belly" are waiting for the battle, and the Camon army, dense lights are advancing in the Houguan Road at a speed visible to the naked eye. The Houguan Road is narrow and can only accommodate 2,000 ships at the same time, but it still looks crowded.

The range figures continue to shrink, and the main and secondary guns are all unveiled. A group of inconspicuous airship formations flew from the rear of the defenders to inspect the wall to prevent the situation of being cut off from the back road again!

"Hold down, don't move!"

"Don't panic, let them in!"

The missiles were loaded, and seeing that the range number was approaching zero, the captains of the ships did not immediately order to shoot, but according to the battle plan, let the enemy advance some more distance.

-10, -50, -100, -300, the numbers on the range table changed rapidly, until it became -500 kilometers, and the command to "open fire" was given, and a dense rain of missiles poured into the pass with a long tail.

The advancing Carmon fleet was held back and could only pause its advance and defend it with all its might. It is easy to attack from outside the pass to the inside of the pass, but it is extremely difficult for the ships inside the pass to attack outside the pass. Neither the numbers nor the terrain were dominant, and the Camon fleet's firepower had already suffered damage before it even touched the defenders of the Blue Domain.

Although all the firepower was used to intercept the artillery fire pouring into the pass, the Blue Domain people arranged a three-story battleship in the fish belly, which was equivalent to intercepting the attack of 15,000 ships with the firepower of 2,000 ships for the Kamon people.

The tracking system was running at full speed, but it made a series of mistakes under heavy artillery fire and the blockage of the pass. Soon, the first layer of the battleships of the Carmon advance fleet was full of holes, and the artillery fire was approaching the second layer.

"Get on the ship shield!"

The combat commander of the Kamon side, a three-colored insect man, saw that the road ahead had been blocked by the fragments of the battleship, so he gave a resolute order.

Usually using a warship as a shield means that you want to be a shield ship with the determination to die. Under the military order, the first four layers of the battleship stopped moving forward and turned on the engine to the test state before flying faster than the speed of light, forming a layer of "light shield".

More than 4,000 "little suns" were formed again in the pass.

"Here we go again. Is this warship driven like this to consume energy? ”

"Watch out for them crashing faster-than-light! It's faster than light in one move! ”

"He hit a fart, he hit it, the artillery fire is so urgent, that kind of speed, he didn't wait for it to hit him, he was gone! Where to hit! ”

"Let's see how it moves!"

As the strategists had expected, the Camon battleship neither collided nor moved, but simply hovered in place, opening up the cannon fire that distorted time and space to tear apart the invasion.

"Report to the sir, find out that the enemy is moving!"

"Detailed report!"

"Behind the shield of the Kamon Army, about 2,000 warships, is moving forward around the wall."

"Do you want to go to the wall to intercept it?"

"This won't work! This will distract our forces, which will fall into their ploy. Activate the Celestial Defenses and destroy them. ”

The situation at the gate was complicated, and the battleships that were circling around could no longer huddle together to launch a light curtain attack, and He Yongnian was full of confidence and prepared to watch the effect of the celestial defense.

However, it was as if it had been calculated in advance: all the large objects were perfectly avoided, the small ones were intercepted, and the gravitational traps were cleverly avoided. The 2,000 ship, unscathed, bypassed the pass, swaggered forward for 600 kilometers, and cut into the pass again.

"Oh no, that cow is telling the truth! Not only our star map, but even our defense map in Pingzu Pass, they have all gotten it! He Yongnian only remembered Wujiang's words at this time, but he still doubted in his heart that it would be easy to get the star map through Hanes's starship trajectory, but if he got the defense map of the entire Pingzu Pass, this was a secret that only the high-level and head of Pingzu Pass could guide. But in any case, the cow's words still have some credibility.

Between the general's thoughts, 2,000 warships slowly "infiltrated" into the wall, first the outer ring battleship opened the saturation interception from the edge of the pass with relatively weak artillery fire, and then immediately opened the "light shield" after completion, and then the second ring battleship, which followed up from behind the first ring battleship to form the second ring "light shield". And so on, the third ring, the fourth ring......

Until the entire pass was blocked again by the "ship shield" composed of "light shields".

This time, the Kamon people who did the "ship shield" in the back end did not usher in the fate of running out of energy and being crushed by a rain of bullets. After the front layer of ship shields is set up, they automatically withdraw from the customs to replace the energy source, and make way for the rear fleet to move forward.

This operation took less than 2 hours in total, and so on. By noon tomorrow, the entire Camon fleet will reach the fish maw safely.

"Heh, we want to take advantage of the large fighting surface in the fish belly to fight them. They took advantage of the small defensive surface in the pass to consume us! Hmph, with their energy, consuming our firepower, we can really think of it. He Yongnian's face was full of sadness, he had long heard that Duke Aimo was a commander who won all battles, and he really saw it today!

"Is there any way to break these shields?"

"It's difficult, this level of space-time distortion, it takes a super-large equivalent cannon to explode near it in order to transfer energy into it and disrupt its protective shell!"

"Hey, if only there were planetary cannons. By the way, where is the cannon! ”

"It's still on the road, the towing is slow, and it will take at least 10 days to wait."

"10 days? We have long been consumed by him! ”

Wei Ran listened anxiously to the conversation between He Yongnian and the strategists, hesitated again and again, but still said what he had been thinking about for a long time.

"They use battleships as shields, and we can also use battleships as cannons to break his shields!"

Wei Ran's words once again attracted everyone's attention.

"Young man, why do you sacrifice this and that at every turn? The life of a soldier is so humble, don't you be a stepping stone to promotion? ”

"Make it clear, I'm talking about the battleship blowing itself up, what's the matter of human life!"

This time, He Yongnian decided to listen to the young man's advice: "Okay, you don't have to fight, you go on, how did you plan it?" ”

"That's right, more than 2,000 damaged ships were withdrawn from Qianguan yesterday. Find those that have no repair value, get people out, take out the remaining fuel, and let them hit. ”

"I'm afraid it's not enough to exchange one for one! Our battleships are all in it, and we can't break through a few floors! ”

"There are not enough battleships, cannonballs come together. Each battleship hits, at least one for one, and will cause a violent disturbance around the perimeter at the moment of the explosion, at this time, only need to adjust the density of artillery fire, add attack disturbance, and it will cause a larger explosion. ”

"Okay, listen to you this time, let's put 500 battleships to test the water first!"

At Wei Ran's suggestion, the tactic of using battleships as shells had to appear for the first time in the war, and 500 battleships did not need to turn on the force field protection under the rain of bullets on their own side, and they could directly get close to the front of the ship's shield.

The moment the battleship and the light shield came into contact, there was a violent burst of light, illuminating all the spectators who were almost blind. When the light dimmed, people began to observe the damage to the shield from the dimness brought by their senses.

500 holes, the disturbance caused by the entire shield was transmitted throughout the ship's shield, and under the seamless thrust of the 500 missile streams, the battleships close to the explosion point also began to burst one after another. The burst point was immediately captured by the supercomputing system, and the missile stream was once again repositioned according to the most disturbance, and a series of explosions emerged one after another. Within 30 minutes, the entire "ship shield" was successfully disintegrated.

"Then the shield, the backing, the front shield. Let's see if they have enough warships to spend with us. ”

Under the order of the tricolor wormmen, another group of ship shields was once again formed in the pass road and the wall, and the front shield moved forward another 600 kilometers.

The shield breaking and the shield were carried out at the same time, and Wei Ran's self-detonation tactics had a good effect in breaking the shield, but also hindered the progress of the Kamon people to a certain extent.

The 2000 battleships could not support 4 waves of broken shields and ran out. He Yongnian calculated the ratio of battle losses, 500 for 2000, 1 to 4, which was also worth it, so he ordered those warships with poor performance to also withdraw excess energy and personnel, and joined the ranks of self-explosion.

The battle lasted for 2 days, and by noon on the third day, the Blue Guys lost 8,000 ships and the Kamon lost 32,000 ships. The attacking fleet, escorted by the ship's shield, finally approached the fish maw. At this time, there were still 3 days left before the first batch of fleets rushed to help.

"The front row of ships is withdrawn and the energy is replaced, the rear row of ships is pressed forward, and the last row is added with another layer. Aim for the hole and saturate the attack. ”

Under the military order, the neat battleship network was adjusted in an orderly manner, and at this moment, all the battleships pressed up became V86.

"Move the whole level forward and seal the gap."

Watching the three-layer protective net be completed again, another command flew out, and the entire shot was panned forward by 300 kilometers, compressing the space in the fish's belly to the limit.

"Shut up group action!"

He Yongnian pressed almost all the treasures, and sent 5,000 V86 warships to the upper and lower ends of the disc-shaped blockade surface in a circular arrangement. At this point, the protective net in the entire fish belly, like a covered bowl, is tightly buckled on the crossing. Battleships coming out from all directions could not escape the attacks in the first five directions of the up, down, left, right, and left.

This time, He Yongnian did not order the self-detonation team to dispatch, but ordered the battleship's firepower to continue to decrease, waiting for the Kamon shield to run out of energy.

Everyone was silent in their hearts for a few seconds, the air condensed, and their eyes were firmly fixed on the 2,000 "little suns". After 90 minutes, the dazzling light slowly dimmed at a speed visible to the naked eye.

"Watch out for fire suppression, they're coming out."

As the light of the shield gradually dimmed, the firepower of the Blue Domain Army gradually increased, and after 10 minutes of continuous shooting, the first "light shield" burst open, followed by the second and third, one after another, until the entire protective net turned into a dark red ruin.

"The outer ring warship is activated, and the whole array is saturated to attack."

"Patrol boats outside the wall have stepped up their patrols. Report the enemy situation immediately! ”

Two commands flew out at the same time. At the same time, the shield of the pass ship was broken, and the Camon fleet was like a bee that had been stabbed in its nest, and with frantic acceleration, it swarmed towards the battleship guarding the pass.

Under the dense rain of bullets, none of the Camun ships could get close to the blocking net intact. But the Carmon people are like this, relying on the advantage of more people and more ships, charge, charge, and charge. Completely ignoring the explosions, explosions, and explosions that greeted them.

"Release the airship!"

The insect man with the three-color pattern gave the order again, if it was a swarm of bees that gushed out just now. Then after this order, the airships that poured out seemed to cause a plague of locusts.

"Report to the sir, a large number of airships have flown out of the battleship Camon and are heading around the wall."

"Blue Domain, the airship army is ready!"

In order to reduce unnecessary casualties, He Yongnian released the airships of the traditional warships early on, and the airship army, which was on a par with the "locust swarm", also entered the pass at the same time.

The blocking battle inside the pass and the airship melee outside the pass made the entire Pingzu Pass form a beautiful scenery in the universe.

"Looks like it's in!" Yuan Tianji, who was far away from the pass, had already witnessed this unprecedented battle, and he expected that with the deployment of Pingzu Pass, he could hold out for at least a week, but he didn't expect that it would last less than three days, no matter what the fate of the checkpoint was, the price paid for Huo Qimeng's return to his position was too great!
