The cannon fodder troops on both sides passed by, and both sides tacitly did not attack each other, and even if these mass-produced cannon fodder were killed, the enemy's warships could be replenished immediately, so it was not worth wasting artillery fire.

At the same time, seeing that the enemy's rear troops were rushing over from the rear at full speed, Ding Yuan couldn't help but show a smile. The enemy's technology tree is not as good as ours, this is the conclusion reached by Dingyuan.

After all, those battleships that came out of the starport in the rear were all just in a state of sub-light speed.

In order to protect the fortress, it takes about half an hour to fly the distance between the portal and the fortress at sub-light speed, and if you jump a short distance, it will not take even a minute to get here.

But the enemy didn't do that, knowing that their lone mothership was likely to be destroyed by Li Nan's fleet. Hundreds of millions of them cannot be a show of weakness to the enemy, after all, no matter how strong the effect of showing weakness to the enemy is, I don't know how to use a mothership to return.

That is, the opponent's technology is still stuck in the era of the first generation of warp navigation, and for the Tyranid Empire, which has already mastered the second generation of warp engines, the technology tree of the Kitari people is obviously one era behind.

The difference between the first and second generation warp engines is very large, the former needs to first increase the speed to sub-light speed, and then through the warp engine, the battleship is propelled into the warp space, the whole process takes about half an hour to several hours according to the difference in technology, and most of this time is spent on speeding up the warship to sub-light speed.

The latter, on the other hand, can directly push the battleship into the warp space when needed, without the need for acceleration. It can even perform short-distance space folds on the battleship, which greatly increases the maneuverability of the battleship in battle.

If the Kitarians had a second-generation warp engine, their warships would be able to leave the range of the starport and immediately make a spatial warp to the side of their mothership. Instead of hurrying slowly through sub-light speeds, as is the case now.

And the engine, which is the most important part of the battleship, is a generation behind, and as for other weapons, there is even less to worry about. It is precisely because of this that Dingyuan is relieved to let the opponent's cannon fodder troops get close to him.

Rather than wasting time in the mutual chopping of cannon fodder units, it would be wiser to let those carrier-based aircraft abandon the cannon fodder units and directly destroy the enemy's mothership. If they only have a lone mothership that has gone deep behind enemy lines, and even the cannon fodder unit of the mothership's escort has been dispatched, what better time to destroy the enemy mothership?

The enemy obviously knew this, so it simply abandoned the defense forces of the mothership, used the mothership to drag the carrier-based aircraft in Dingyuan, and then eliminated the battleships in Dingyuan's fleet through those cannon fodder troops. Those carrier-based aircraft are just cannon fodder that can be mass-produced through the production line, and it is meaningless to destroy them, and the battleship, as long as it is eliminated, then it will be difficult to replenish it again, unless the troops are transferred again.

Of course, Dingyuan also saw the enemy's thoughts clearly, but her fleet was different from this ordinary situation. In her subspace, there are still a lot of battlecruisers accumulating dust, but her mental strength is not enough, so she can't use them.

In fact, the battlecruiser is the carrier-based aircraft of Dingyuan, and those small planes are just the next level of carrier-based aircraft, but it is these small planes that will consume a lot of her mental power. If Dingyuan wants to control a larger number of battlecruisers, he will have to wait for her level to be higher.

And now, both sides are already within range of the attack. The first to fire was the big kun of those cannon fodder troops of the Chitari, and the main guns on the head armor of more than two hundred big kuns fired a salvo at the same time, and more than two hundred beams were fired at the front row of battlecruiser formations at the same time.

However, a huge dark blue shield protected the entire fleet, and the shield resisted all the beams shot by those big kuns.

The United Shield System is a new technology developed by Nova . Through this system, the shield generators of the individual battlecruisers in these battlecruisers will be connected when the distance between the multiple battlecruisers does not exceed a certain value, thus forming a shield that protects all the battleships. And the strength of this shield is stronger than the sum of those individual shields, and this effect is not as simple as 1+1=2.

The Great Kun's attack was useless, which was the result of what had been encountered before. However, the main purpose of these attacks is to drain the energy of the enemy's shield. The benefits of the Combined Shield system can also be reflected at this time, this shield is maintained by the common function of all combined warships, so the staying power of the shield is also greatly enhanced.

And these main artillery attacks of the Great Kun can't even make ripples in this combined shield. If you want to consume the energy of the shield, the speed of consumption is actually not as fast as the energy generated by the Ghost Power Furnace of the shield function.

The Kuns stopped after the first wave of attacks, and they were charging the second shot of the main cannon. The other Kitari soldiers continued to drive on their flying machines. Although they can also attack their targets at this distance, this distance is enough to consume most of the power of the beam gun in their hands, and it is difficult to use the enemy's shields, so they need to get closer before attacking.

As for these flying machines, Dingyuan didn't care about them at all, and when they approached the shield, those armored infantry regiments stationed on the various platforms of the battleship would also take action to clear them.

And the battlecruisers in the front row, the laser artillery crews in the front row arranged in the bow of the ship have risen from the turret, and then they have aimed at the big kun in the distance. Each giant kun was given a beam of light in return, for a total of multiple beams.

As biological warships, the mobility of these Great Kuns is inferior to that of ordinary mechanical warships, so these beam Great Kuns cannot dodge, and the beams directly hit the Great Kun's head armor in the next second.

However, the Chitari people are obviously aware of the shortcomings of the Great Kun, so the armor of these Great Kuns used in the universe is obviously strengthened, and it is difficult for even high-output laser cannons to penetrate this layer of surface armor.

After the beam dissipates, the reflective beam coating on the surface of the armor also plays a good role in heat dissipation. However, these battlecruisers in Dingyuan are obviously different from the old warships sold to Fury, these beam gun sets shoot out not gamma rays generated by the fusion power furnace, but ghost energy beams generated by the ghost power furnace.

The characteristic of ghost energy is that it is very erosive and radiant to matter, so if it is used in the atmosphere, it will have a great impact on the surrounding environment, but of course, there is no such concern in space.

And Li Nan will install ghost batteries in his base as a defense, because Li Nan has the ability to clean up these pollution.

Therefore, it is best to use a shield to defend against the Spectral Beam. And these big kuns without shields, although their armor has been strengthened, the part that just hit the ghost energy beam has been corroded into a small pit with a diameter of tens of centimeters at this time. Moreover, this small pit is constantly corroding the metal on the side, and as the corrosion intensifies, the area and depth of this small pit can also expand at a speed visible to the naked eye.

On the other side, the mothership of the Kitari. At this time, those small planes were already close to the mothership, and the beam guns on the planes were also using ghost beams. However, the beam guns on these planes, which are powered by ghost batteries, are much less powerful than the gun crews on battleships.

To Li Nan's surprise, the Kitari people had not yet developed shield technology. This mothership, which is about the size of the Leviathan, actually relies on its surface deck to resist the damage of the ghost beam.

However, the surface deck of this mothership is much stronger than the armor of the Great Kun, and the power of the beam guns on the aircraft is not too strong, and each beam can only create a small hole the size of a thumb in the deck of the mothership.

However, although the power has decreased, the corrosive energy of the spectral energy has not diminished, and the rate of fire is much faster than that of the laser cannon group, and these beam guns can fire 40 beams per minute.

The small planes, which had been 3 out of 5,000 planes, had left a large number of small holes in the surface deck of the Kitari mothership after a minute of intensive fire. And the residual ghost energy in the small hole quickly corroded towards the nearby deck.

And the enemy's mothership did not fail to counterattack, but as a mothership, she did not have a frigate, relying on her own meager firepower alone, she could not cause damage to these very maneuverable aircraft at all. And occasionally due to the dense formation, they were unable to dodge the attack, but the individual shields of these planes easily resisted the attacks of these close defense guns.

Soon, the remaining ghost energy had been consumed, but by this time there was already an area of nearly 10,000 square meters on the surface deck of the mothership, which had been corroded to a depth of almost 1 meter.

This piece was joined together by corrosion in the small holes caused by the intensive attack of the small planes before. Without the massive damage, it would have been impossible to inflict damage on the mothership with these thumb-sized holes. It was really because of this that Dingyuan was sure that his small plane would be able to take down the mothership before the enemy's reinforcements arrived.

During this time, the fleet had already fired 5 waves of beams at the opposite Kun, and the Kun had also counterattacked three waves. However, it was obvious that Dingyuan's side had a complete advantage, and after several waves of attacks, even the light on the shield had not weakened at all. Looking at the shield data on the screen in the bridge, the shield energy value is still at full value, and Dingyuan nodded with great satisfaction. For Nova's new equipment, Dingyuan is still very satisfied.

On the other side of the big kun, after experiencing the baptism of the waveless ghost energy beam, these big kun have already suffered casualties. In fact, after the third round, these big kuns no longer dared to stand and fight with Dingyuan's fleet.

Although they are slow to move and maneuver, these large kuns were able to dodge the beam with luck. However, with the corrosion of the ghost energy, those ghost energy has corroded through the surface armor of the big kun, officially causing damage to the body inside, which also slows down the movement speed of the big kun.

At this time, there are only 120 large kuns left that can still swim, and the rest are floating quietly, some are dead, and some are suffering from the erosion of ghost energy, and are in a state of dying.

And the more than 8,000 flying machines have also come to the edge of the shield, and a large number of beam guns are pouring fire on the shield.

On the fleet's side, the soldiers who boarded the platform had already exchanged fire with the flying machines outside. However, the aircraft relied on its superior agility to control the aircraft to fly around the shield and avoid the attacks coming from the platform. The number of downed aircraft is also not 100.

Of course, the reason for this result is that Dingyuan released the water, and the close defense guns on the battleship did not fire. And in order to give them hope, Dingyuan quietly reduced the energy value of the shield by 20 percent. And the most intuitive manifestation of the sunshade is that the dark blue shield, which was originally very strong, suddenly became a little darker in brightness.

It's really because of this performance that the enemy thinks that their attack has worked. They are death squads, and as long as they can weaken the enemy's fleet, their mission is accomplished. The mothership on my side is no longer good, but even before it is destroyed, it will bite you.

In the face of this situation, the attack on people is more vigorous, which also causes the cannon fodder to slow down the speed of the coquettish movement in order to increase the DPS output. And this is exactly what Dingyuan wants, while retaining his own strength, to easily destroy the enemy.

As the battle continued, five minutes later, the Kitari were still attacking frantically, but by this time they had all been destroyed, leaving only piles of wreckage floating in the universe.

And the 8,000 besieging fleet aircraft, at this time there were less than 2,000 left, but their results were gratifying. Although they couldn't break through the nasty shield, the brightness of the dark blue shield had been greatly weakened under their lifeless attacks, and it was about to reach a precarious level.

After all, the shield oil tiger, after being turned on at full strength, has been surrounded by their Kitari for so long, and the energy has been almost consumed. And they felt that they could fight for it, and break the enemy's shield before the group was destroyed.

The shield had diminished in brightness under the firepower of their beam guns, and even the weakest point felt like it could be pierced with just one more shot.

We had a great advantage in this wave, hitting all the firepower, giving the enemy a general attack, and breaking the shield before we were wiped out.

The Kitari mothership, which was also already in danger, gave the final order to the cannon fodder who were besieging at the last moment.

"Seeing their efforts, even I can't help but want to help them, so let's reduce the strength of the shield by another 5%. Go for it, there's only 50% of the shield strength left. "Of course, all that the Kitari see is just an illusion.
