The whistling of cannonballs piercing the air echoed through the sky, piercing through the hard shell of the electromagnetic beetle with a white trail. The explosion shattered the beetle in pieces, and the spiders were unable to dodge and were crushed into patties by their massive bodies.

"The beam cannons focus on one Eritan every group of three, be careful not to waste ammo." Yang Jingzhong sat in the captain's chair, and the seat belt held him firmly in place.

I have to say that Gao Qianhui's attack is still quite terrifying, the number of Eritan in each wave is more than ten more than the previous wave, and the gap between the attacks is also decreasing one minute at a time, which makes Yang Jingzhong have to reduce the use of resources on the ground, increase the number and technology of warships as much as possible, and at the same time have to use the fleet very carefully, each battleship is a vital treasure. But even then, by the end of the fourth offensive, the number of fleets could not return to their peak. The ground defense line was also drastically reduced, and the depth of the defense was reduced from 200 kilometers at its peak to 50 kilometers, because the shortage of resources prevented the loss of ground losses from being replenished in time, so that the fleet had to allocate valuable firepower to the ground forces to provide bombing support.

Yang Jingzhong seriously considered whether he should develop a Hanhai-class planetary warship, and after Wolfe's simulation, he finally dismissed this idea. It takes quite a lot of resources and technology to build the Hanhai class, not to mention that the planetary warship is positioned as long-range fire support and cannot fight near normal planets. In such a combat environment in the orbit of a planet, if you forcibly use a planetary battleship, I am afraid that you will be the first to die. Instead of pursuing the biggest and strongest, it is better to build more cruisers and destroyers, and Yang Jingzhong still knows the difference between the evil tiger and the wolf.

By the end of the ninth attack, he only had three Sun-class battleships, twenty Haoyue-class cruisers and fifty destroyers, which were far from the five provincial fleets at his peak, and the number of Eritan he was about to face reached an unprecedented one hundred and twenty, which was even more than the number of warships, and all Yang Jingzhong could do was to use all the last resources to build Meteorite-class destroyers.

"Sir, the final wave is only ten seconds away, are you ready?"

"Alas, come on, survive this wave, and you will be able to enter the best department." Yang Jingzhong stretched hard, and the high-intensity battle that lasted for more than an hour made his nerves tense to the extreme, and he must not relax at this time.

All the Vulture-class fighters took to the skies, unlike before, he did not let these fighters fight the scorpion swarm, but concentrated near the fleet, with the primary purpose of protecting the fleet.

Four of the remaining ten nuclear bombs were installed on space-based electromagnetic railgun platforms, ready to kill as many scorpions as possible.

Before Yang Jingzhong had fully adjusted the fleet, Gao Qianhui's attack had already arrived, and the insect tide that covered the sky was even more terrifying than a desert storm.

"Wolf, prepare to launch a nuclear bomb and hit as many places as you can."

Yang Jingzhong still trusts Wolfe's computing skills, and has relied on him several times before to save the day, but this time Wolf failed. Before the nuclear bomb flew to the designated position, the originally dense swarm of insects scattered in one go, four nuclear bombs, grandma's four, not even a fart exploded, so angry that Yang Jingzhong completely became a Zu'an person.

Meteorite-class destroyers were the first to fire, and for such a dense swarm, it didn't even need to aim to achieve a 100% hit rate. The scorpion that was hit in front exploded into a cloud of green blood, and the scorpion behind still rushed straight forward. The Meteorite-class battleship was completely vulnerable to an attack of this magnitude, like a green leaf drifting on the rough sea.

The outer layer of firepower was quickly breached, and the army of detonation bugs followed.

"Wolf, open the gravitational wave shield."

The gravitational wave shield generator in the middle of the fleet opens up a large position, covering the entire fleet in it. Although this shield could not completely reflect the opponent's energy back as Yang Jingzhong imagined, it could at least give these high-speed flying detonators a lot of sticky effect.

The Vulture-class fighter took the remaining six nuclear bombs and rushed into the middle of the Shock Explosion Worm that had dropped sharply in speed for the first time, but this time the Shock Explosion Worm was not concentrated as before, but attacked in waves. After this wave, there are only two nuclear bombs left, and there are at least five waves of detonators, and it is almost impossible to win if they continue like this.

"All Meteorite-class battleships, change formations, and line up phalanxes!"

"Sir, ...... you" Wolf's eyes widened in disbelief, giving up the spherical formation at this time was no different from looking for death, could it be that the old man in front of him had completely lost his mind.

"Do what I tell you to do, and in extraordinary circumstances, you have to use extraordinary means to win." Yang Jingzhong's fingers were sensitive to mark the designated position of each Meteorite-class battleship on the star map, and the fleet at this time was more like an ancient phalanx of spearmen.

"The shield is concentrated in the bow of the ship, and the front-mounted laser cannon fires directly ahead!"

The destroyer engine power was increased to the maximum, and the scorpion swarm came to a hedge. The scorpion swarm was caught off guard, and for a moment it was too late to brake, and it crashed into meat sauce on the strengthened shield.

When the bugs come to their senses, the Shock Worm begins to slow down and instead stick to the shield, exploding at the same time when the number reaches a certain level. Under the ravages of such a terrifying storm of energy, the shield began to crack, and then shattered like glass. But the destroyers did not show the slightest intention of slowing down, and rushed directly towards Eritan.

This hand directly disrupted the offensive rhythm of the swarm, Gao Qianhui was not stupid, of course he knew that the other party was coming for his Eritan, if Eritan was killed too much by the other party, the remaining scorpion swarm and shock insects could not penetrate the shield of the Scorching Sun-class battleship. The large forces of the swarm began to quickly retreat to protect Eritan, and the tentacles also took action, trying to annihilate all these destroyers in advance.

"Moon-class cruisers, attack those tentacles and detonation bugs. A Sun-class battleship that concentrates its fire on Eritan, which is the farthest away. ”

The pillar of light crossed the destroyer array and hit Eritan's body, and the tentacles cleared a lot of obstacles for the advance of the Meteorite-class battleship. But the huge scorpion swarm was still unstoppable, and the scorpions landed on the battleship, gnawing at the battleship's armor and external reactors, and more than a dozen battleships lost control and deviated from the course of the charge. The tentacles braved a hail of bullets and bullets, tying the battleship like a mummy. The Shock Bugs could only crash head-on into the battleship because of their speed, and the indestructible shock wave made the battleship brake sharply as if it had hit an obstacle, and any battleship that lost its speed was a fish on the anvil and could only be surrounded and annihilated by the scorpions. Most of the warships have gone through ups and downs, and the hull of the ship is billowing with smoke, and I am afraid that the crew has all been sacrificed, leaving only the computer control of the battleship itself to complete this final mission.

Beautiful fireworks burst into the night sky, a fantasy song to hell that the destroyer had given to Eritan. The Meteorite-class destroyer itself has two nuclear fusion reactors, and with the huge kinetic energy of the hull itself, it is simply a super-large armor-piercing grenade for Eritan. Dozens of Eritans fell into the sea of stars under the attack of this suicidal charge, and less than fifteen Eritans were powerless to resist in front of the three Sun-class battleships. Knowing that they were no match for the Sun-class, the Shock Worm and the Scorpion turned their guns on the Haoyue-class cruisers, destroying all of these slightly weaker defenses.

The space side has freed up its hands, the ground defense line has been beaten to the doorstep, the outer defense of the base has been destroyed, and the remaining infantry company has retreated to the innermost layer of the base in despair, and if it is a minute late, I am afraid that the base will be completely destroyed.

As the spiders were elated to deliver the final blow to the base, a whistling sound could be heard overhead that pierced the air. First, the electromagnetic beetle seemed to be struck from the head with a hammer, and its huge body swayed twice before falling to the ground, and the ground was instantly plowed out of a deep pit, and the pit buried the corpses of countless spiders.

The first round of artillery fire killed all the beetles, and this is only the record of the main gun, and other laser cannons of various sizes and powers rained down on the spiders, killing all the spiders closest to the infantry with precision.

The automatic loader quickly loaded the railgun with the next shell, which Yang Jingzhong specially prepared for the sharp-toothed locust.

The shells burned through the atmosphere like meteorites, and thanks to the protective shells on the outside of the shells, they were not detonated prematurely, but were controlled by a delayed fuse to explode at an altitude of three thousand meters. Raindrops of debris fell on the locusts and spiders, cutting through deep bloody wounds. The white phosphorus from the shells stuck to the wings of the locusts, and no matter how much they fluttered, they could only turn into a foul-smelling corpse.

"Alright, Wolf, this should be all done, right?" Yang Jingzhong breathed a heavy sigh of relief, his tense nerves finally relaxed, and the tiredness rushed to his brain like a tidal wave, almost making him faint to the ground.

He picked up his bag and prepared to leave, only to find that the scene around him had not returned to its original state, and the countdown to the expected attack wave sounded again, and Wolf's voice full of confusion came from behind him.

"Sir, I, I don't know why, you still need to withstand four rounds of attack."
