As the fleet led by Zhu Lei gradually approached, the atmosphere on the home planet of the Kara civilization became more and more tense, after all, all the people of the Kara civilization who were at war with a fifth-level civilization had no bottom in their hearts, you must know that the Kara civilization is a civilization that understands the level of interstellar Chinese, not those who have just walked out of their home planet, Yelang arrogant civilization.

They knew very well the gap between the fourth-level and fifth-level civilizations, so for the fact that they were going to fight a fifth-level civilization, all of them were feeling weak in their hearts, even with the help of the black bear civilization.

After all, this is not the black bear civilization itself and this civilization is at war, it will definitely not be desperate to fight with this civilization, if the war is unfavorable, they can leave at any time, not to mention that because the distance between their own civilization and the black bear civilization is not close, the black bear civilization will not be able to catch up for a while, and they must fight for a year before the black bear civilization can come, not to mention that the black bear may not come for thousands of miles!

Although the total number of combat spaceships of the Kara civilization is as high as more than one million, and the fleet led by Zhu Lei is only about 200,000, with a ratio of more than 5:1, all the people in the Kara civilization are more pessimistic about this war, because the fleet of the earth civilization is getting closer and closer, and even ordinary people on the home planet of the Kara civilization can clearly see the fleet of the earth civilization through a telescope.

Although there is a 5:1 gap between the total number of ships in the fleet of the Earth civilization and the Kara civilization, the very quality is far from the difference, and the largest spaceship of the Kara civilization is the space cruiser purchased from the black bear civilization, which has a tonnage of only six million tons and a length of no more than five kilometers.

And the fleet of human civilization, there are tens of thousands of spaceships of more than 6 million tons, not to mention the flagship of the fleet, the flagship of the fleet of human civilization has a tonnage of more than 10 million tons, and the length is more than 20 kilometers.

So whoever sees such a big gap between the two fleets will inevitably be pessimistic. What's more, the gap between the scientific and technological strength of the two sides is also very large, although the two sides are not the same as the Kara civilization in terms of science and technology level, the human civilization is a fifth-level civilization, but the same as the Kara civilization, it is a fourth-level civilization, but because the human civilization is a mixed civilization, many technologies that cannot be achieved through existing science and technology can be achieved by means of cultivating civilization.

For example, most of the spaceships in the human civilization fleet do not have protective shields, but a small number of them in the space war world have protective shields, because the armor of these spaceships is painted by human monks, that is, cultivators, on these armor A large number of sigils.

This makes these very similar to the existence of protective shields of technological civilizations, but unlike protective shields, since these sigils are on the armor of spaceships, each sigil is a single and separate, and there is no overall defense like the protective shield of technological civilization.

Moreover, the energy of the rune seal used in the cultivation method is limited, and it can only defend against one or several attacks, which means that after the same part of the spaceship is attacked or attacked once, the rune seal on the armor will collapse.

The protective shield of scientific and technological civilization is different, as long as the energy of the spacecraft is not exhausted, then the protective shield will always provide protection for the spacecraft, but when the energy impact exceeds the protective shield, the protective shield of scientific and technological civilization will also collapse.

Although it is said that there are many inconveniences in using the defense means of the cultivation civilization compared with the scientific and technological civilization, it is undeniable that the defense means of the cultivation civilization also have its own advantages, that is, even if the energy of the spaceship has been completely depleted, these defensive runes on the armor will not collapse, and even if the defense power exceeds the rune itself, the rune seal will collapse, and it will not completely collapse like the protective shield of the scientific and technological civilization, and the collapse will only be the defense of the place where it is hit, and will not affect other places.

Therefore, the performance of the spaceships of the two civilizations is very different.

……

Finally, when the human fleet was only 1.5 light-years away from the Kara civilization home system, the speed began to slow down, and finally stayed at 1.2 light-years away from the Kara civilization home system, because less than 0.2 light-years away from the fleet, there was a Kara civilization fleet waiting for the arrival of the human fleet, and they were ready to fight at this time.

In fact, the Kara civilization has three fleets outside of their home galaxy, each of which has about 200,000 ships, and each fleet is about the same as the total number of human civilization's space fleets.

No civilization in the universe wants war to break out in its home galaxy, and the Kara civilization does not want war to break out in its home system.

After the space fleet led by Zhu Lei stopped and reorganized, it began to accelerate again and flew towards the interception fleet of the Kara civilization, but as time passed, the space fleet led by Zhu Lei was divided into two echelons, and the main fleet began to slowly fall behind.

And rushing ahead is the vanguard fleet of the human fleet, which is composed of a hundred cruisers, a hundred aircraft carriers, tens of thousands of destroyers and a huge number of frigates, the total number of ships of the entire vanguard fleet has reached about 50,000, and the more than 150,000 ships of the main fleet stopped at a distance of 50 astronomical units from the Kara civilization interception fleet after sailing a distance.

At this time, the Vanguard fleet in front also began to change, the entire Vanguard fleet began to divide into sub-fleets one by one, and flew towards the other side at the fastest speed, when it was only 30 astronomical units away from the opponent's fleet, all the spaceships of the Pioneer fleet reached 50% of the speed of light.

At this time, all the electromagnetic railguns of the Vanguard fleet fired one after another, and with the blessing of the speed of the spacecraft, the speed of these shells reached more than 70% of the speed of light, which is also the highest speed that human beings can achieve when firing shells.

After all, the level of human science and technology is now only at the level of a fourth-level civilization, and it is impossible to achieve that the shells fired by electromagnetic railguns exceed the speed of light, because this is not something that can be reached by intermediate civilizations, and perhaps only when the level of civilization reaches the advanced level, it is possible to make the shells fired by themselves exceed the speed of light.

However, human civilization can make its own cannonballs shoot at a speed of 70% of the speed of light, which is also quite remarkable, you must know that most of the fifth-level civilizations in the entire galaxy have not yet been able to make their own cannonballs reach 70% of the speed of light.

So comparatively, so comparatively, the electromagnetic railgun fired by the human fleet is already quite remarkable that it can reach 70% of the speed of light.

I saw that each warship of the human vanguard fleet emitted bursts of blue light, which was generated by the energy of the electromagnetic railgun on the spaceship reaching its limit, and then an object burned red by energy flew out of the muzzle of the electromagnetic railgun, and then this object flew out not long before it slowly darkened and finally slowly merged into the background of the universe.

After the first launch of the electromagnetic railguns, it was not long before the electromagnetic railguns were fired again, and the cycle continued.

When all the spaceships fired nearly 200 shells, the speed of the spacecraft slowed down, after all, the electromagnetic railgun also has a considerable recoil force when it is fired, although with the help of various mechanical and other scientific and technological means, the recoil force of the electromagnetic railgun when firing the shells is already very small.

However, when the spaceship reaches 50% of the speed of light, the impact of the electromagnetic railgun firing is still very large, and every time an electromagnetic railgun shell is fired, the speed of the spacecraft will be greatly reduced, even if the ship's engine is turned on.

For example, the current Vanguard fleet, due to the continuous firing, the speed of all the spaceships in the Vanguard fleet has been reduced to less than two percent of the speed of light.

You can imagine the huge amount of energy generated when the electromagnetic railgun is fired.

However, at this time, the vanguard fleet was less than fifteen astronomical units away from the other party, and 15 astronomical units had already entered the combat area for a fourth-level civilization, so at this time, the Kara civilization had also entered a state of readiness and activated all the spaceships and various instruments on the spaceships.

However, at this time, the spaceships in the Kara civilization fleet are all alarms, after all, the Kara civilization is not the Ruhr civilization, the Kara civilization is a fourth-level civilization, and the Ruhr civilization is only a third-level civilization, not to mention that the spaceships of the Kara civilization, especially the large warships, are equipped with the radar profile and other equipment of the black bear civilization.

So when the electromagnetic railgun shells fired by humans were less than five astronomical units away from them, the detection equipment on their ship finally discovered these incoming shells.

However, at this time, although they found the incoming shells, but the time was a little late, after all, these electromagnetic railgun shells fired by humans were not aimed at a certain spaceship, but fired in a facet, after all, the two fleets were so far apart, and the speed of the electromagnetic railgun shells was only 70% of the speed of light at the fastest, and the slower the shells fired by the electromagnetic railgun in the back.

Therefore, if you aim at a certain spaceship and launch, it is impossible to hit at all, after all, the opponent's fleet is also moving.

Although most of the warships in the fleet of the Kara civilization were alarmed, the Kara civilization was a fourth-level civilization that had experienced war after all, and it had a lot of experience in space warfare. Therefore, all the spaceships of the Kara civilization began to disperse, after all, as now, the spaceships are concentrated and are the most vulnerable.

When all the spaceships were dispersed, the Kara civilization also began to fight back, although the shaped cannon they used to attack at this distance, even if it hit the other party, it would not have much power, but it was not their style to only take a beating and not fight back, although at this distance, even if it was a cruiser they bought from the black bear civilization, that is, their capital ship, the cannonballs fired by the main gun could not cause any damage if they hit the opponent's large battleship, after all, a large battleship is not a small battleship, However, the threat to small warships is very high, so the fleets of the Kara civilization have also begun to fire at the vanguard fleet of mankind.

When the human electromagnetic railgun shells arrived only 0.5 astronomical units away from the Kara fleet, the Kara civilization also began to counterattack, and all the main guns of the Kara civilization emitted bursts of energy fluctuations, and then one by one the fireball-like energy cannonballs flew in the direction of the human fleet, but when they flew out of a distance, they met with the electromagnetic railguns launched by humans, so from a distance, not far from the Kara civilization fleet, bursts of fire were emitted from time to time, which was generated by the collision of the energy cannon shells sent by the Kara civilization and the electromagnetic railgun shells of humans.

Not long after the Kara civilization fired the shells, the electromagnetic railgun shells fired by the human civilization finally reached the area where their fleet was located.

"Boom!" As soon as the light flashed, a medium-sized battleship flying in front of the Kara civilization fleet suddenly flashed, and then the entire battleship began to disintegrate, and it didn't stop until more than halfway through, and then the back half of the battleship also appeared in the rolling fire, the medium-sized battleship is a kind of main warship of their civilization for the Kara civilization, and it is also the backbone of their current fleet, after all, the large warships of each fleet are very limited, Moreover, the materials needed to build a large space warship and the personnel required to operate the warship are very large, and it is impossible to manufacture and equip them without limit.

Not far from this battleship is a large spaceship, this large space battleship is the space cruiser that the Kara civilization purchased from the Black Bear name, and this battleship is the flagship of their fleet.

At this time, the commander of the fleet was sitting calmly in the command hall, although the various equipment in the space cruiser made by the Black Bear Civilization was very awkward to operate for the Kara civilization, but the personnel in front of him who controlled the spaceship were very familiar with the operation, after all, this cruiser had been beautiful enough for a while, and all the operators on this battleship were the elite of the Kara civilization.

At this time, the medium-sized battleship next to him was directly hit and disintegrated, which was a very big impact on the personnel on this cruiser, and even the fleet commander above the flagship was taken aback.

In fact, the commander of the Kara civilization fleet has already overestimated the fleet of human civilization, after all, in his eyes, the human race is a fifth-level civilization, but he found that he still underestimated the attack of human civilization.

You must know that this is a medium-sized battleship, even if he uses the flagship he is on, it is impossible to destroy a medium-sized battleship at once with a main gun attack, let alone directly dismantle the medium-sized battleship.

At this moment when she was stunned, the warships in the fleet led by him were shot one after another, and the small battleships directly turned into space fragments, after all, the longest small spaceship of the Kara civilization did not exceed 150 meters, and the positioning was only about 100,000 tons, so the small spaceship of the Kara civilization would be directly destroyed as long as it was hit by a human cannonball, even if it was an electromagnetic railgun shell launched by the smallest human space warship, it would be the same if it was hit, after all, the speed of the first wave of electromagnetic railgun shells reached the level of 70% of the speed of light.

Even a fist-sized stone can generate a huge amount of energy when it hits an object at 70% of the speed of light.
