Because in their previous battles, they basically encountered civilizations that used energy attacks, and the distance of energy attacks was generally impossible to launch an attack at such a long distance.

Therefore, these biological warships were suddenly blindsided after being hit head-on, but then they immediately reacted and continued to rush towards the Ming Empire warships.

As time continues, the electromagnetic railgun attacks of the Ming Empire are becoming more and more intensive, and the hit rate of the vital parts is getting higher and higher, and the losses of these biological warships of the entire biological civilization are getting bigger and bigger, although the loss is very large, but for the biological civilization, this little loss is nothing at all, even if all the fleets on the blockade line are wiped out, it is only a drop in the bucket for the biological civilization.

So although the losses are very heavy, the biological ships of these biological civilizations are even more crazy, and with the passage of time and the proximity of distance, the biological warships of these biological civilizations have also issued their own attacks, and the attacks of biological civilizations are very different from mechanical civilizations, but in general, they are also divided into energy attacks and physical attacks.

It's just that the attacks of biological civilization are corrosive, whether it is the energy attack of biological civilization or the physical attack of biological civilization, due to the characteristics of biological civilization, which contains negative energy, and negative energy is very corrosive to matter, even if it is protected by a protective shield, after being hit, these negative energy will be pinched on the protective shield and then gradually corrode these protective shields until these corrosive energy disappear.

And the energy attack of the biological civilization is also very strong, after all, the other party is also a space battleship belonging to the fifth-level top civilization, but it is much weaker in terms of physical attack, of course, this is only relative to the Ming Empire, compared to other civilizations, the physical attack of this biological civilization is already very powerful.

After all, no matter how powerful the metallurgical technology of the Ming Empire is, no matter how advanced the energy shield is, it will still collapse after being attacked many times, not to mention that the attacks of biological civilization are also corrosive, and these small assault ships and ultra-small spaceships are more tolerant of devastating blows.

However, since these assault ships, as well as small and ultra-small spaceships, are consumables, and the pilots of these spaceships are all people from the Baiyun Civilization, it doesn't matter to the Ming Empire at all.

After all, there will definitely be casualties in the war, not to mention that the casualties of the Ming Empire at this time are not large, after all, there are only one or two operators in each small or ultra-small spaceship, even if there is a loss of one or two thousand ships, the energy loss is only a negligible amount for the entire fleet.

Although the medium-sized spacecraft also suffered losses, none of them have been sunk until now, but the damage is relatively large, and the casualties are not large.

However, as time continues, the attack of biological civilization continues, so the next losses will be even greater.

And Zhu Lei, they also found through the radar that those biological warships that were not on this line of defense were still rushing here one after another, and Zhu Lei couldn't sit still when he saw this situation.

After all, there are enough biological civilization warships on this defense line, and if you add that they come one after another, it is simply endless and they can't finish fighting, and Zhu Lei has a limited number of warships in their fleet, especially those small and ultra-small space warships.

As the distance between the two sides got closer, finally the other party entered the attack range of the weapons of the Ming Empire and other weapons, so various weapons began to fire one after another, laser beam weapons, particle beam weapons, and photon weapons. Mass weapons, quantum weapons, and so on all fire.

But Zhu Lei found that most of these energy weapons did not cause much damage to these biological civilization warships, and even energy weapons that were originally very effective against other scientific and technological civilizations, but when attacking these biological civilization warships, the efficiency was not great, and it was not even as good as the damage caused by small electromagnetic railguns.

For example, laser weapons, photon weapons, and particle beam weapons, the damage caused by these energy weapons to these biological civilizations is very limited, and even the damage caused by attacks is not as strong as the healing ability of these biological warships themselves.

You must know that these weapons are very effective for scientific and technological civilizations below level 5, although the power of civilizations above level 5 has decreased, but the damage to the protective shield is very large.

Zhu Lei took a closer look and found that it was precisely because the energy of these energy weapons was too concentrated that the wounds caused were very small, and even after penetration, they could heal quickly with the healing ability of biological warfare agents.

And if this continues, the energy in the fleet will definitely not be enough, after all, the energy in the entire fleet can only last for a few years under such a high intensity of consumption.

You must know that this is a space war, and in fact, it is energy and logistics, but Zhu Lei and they are in such an isolated state, and the energy of the entire fleet can support it for several years, which is already very remarkable.

If it is replaced by a space warship of another civilization, under such high-intensity war conditions, it is already very remarkable to be able to support it for a few months, let alone support it for several years like the Ming Empire.

Seeing this situation, Zhu Lei immediately adjusted the strategy of the fleet, and ordered to stop all weapons that had little effect on these biological civilization warships, and increase the frequency of attacks by other weapons.

When Zhu Lei's order was issued, it was obvious that the damage efficiency of the entire fleet against the enemy was much higher, and the best killing effect was the photon cannon, as well as electromagnetic railguns and other weapons with physical damage.

And as these biological warships approached, Zhu Lei's fleet losses became bigger and bigger, and even the medium-sized space warships had already been destroyed, but at this time, Zhu Lei couldn't care about the losses.

Because in order to better deal with the spaceships of these biological civilizations in the future, in addition to breaking through the blockade, they must find a way to capture a biological warship of biological civilization for research.

After all, with such a high level of civilization, Zhu Lei and they encountered it for the first time, not to mention that this was a biological warship of an alien civilization.

Zhu Lei had a hunch that if he could capture a biological civilization warship this time, it would be very beneficial to the future war, and at the same time, it would also be of great help to the biotechnology of the Ming Empire in the future.

Although the Ming Empire is still dominated by scientific and technological civilization, it has not given up the development of biotechnology, not to mention that the Ming Empire also has a subsidiary civilization of biological civilization, so no matter what, Zhu Lei has to find a way to capture a deep civilization warship this time.
