Even the space cities of the Baiyun and Atlantean civilizations have become raw materials for building warships, so it is impossible to stay in the original star system.

So they had to take small and medium-sized space warships and follow their fleet to the globular cluster ahead.

Although these small and medium-sized warships are already absolute behemoths in the eyes of the Atlantis civilization and the Mandala civilization, Zhu Lei and the others know that these spaceships have a diameter of nearly twenty or thirty kilometers, which is even bigger than those space cities of the Atlantis civilization and the Baiyun civilization, but on the battlefield of the sixth-level civilization, these small and medium-sized space warships are definitely cannon fodder.

As the ships were all activated, they flew towards the globular cluster in front of them, and when the speed reached a certain level, the warp engine was activated, and the entire fleet began to enter the superluminal phase.

However, although their original location was only more than a thousand light-years away from the globular cluster in front of them, with the current level of technology of the Ming Empire, it would take several warp voyages to reach that globular cluster.

Moreover, there are countless alien civilization patrols in the middle, and they don't have to think about it if they want to reach the globular star cluster directly, but now Zhu Lei and they don't have to worry, because the blockade line arranged by the alien civilization in front of them, after Zhu Lei's observation for more than a year, they were pleasantly surprised to find that most of the civilizations on these blockade lines are some biological civilizations below level five.

And the biological civilization below the fifth level can't find the spacefleet that is traveling at warp speed, maybe these civilizations also have some instruments in their hands that can detect spaceships flying at warp speed, but the fleet of the Ming Empire is so large that it can sail at warp speed, as long as it is not a fool, the low-level civilization will definitely not intercept it.

However, after passing through the periphery, it is more troublesome to enter the globular star cluster, because the second and third blockade lines are not composed of low-level civilizations, and these two blockade lines are all composed of fleets of biological civilizations above level 5, but fortunately, the fleets on these blockade lines are not too many, and they are basically composed of small and medium-sized space warships, so they can only break through these two blockade lines.

Sure enough, as Zhu Lei and the others expected, when Zhu Lei's fleet passed through the first blockade line in warp sailing, the biological civilization warships above the first blockade line did not react at all.

After passing through the first blockade line, Zhu Lei and the others continued to fly towards the second blockade line, but as Zhu Lei and the others got closer to the second blockade line, everyone's hearts became more and more nervous.

Because the first blockade line and the second blockade line are completely two concepts, because the space warships above the second blockade line are all space warships of the fifth-level civilization, and the spaceships of the fifth-level civilization can already vent and attack the spaceship that is sailing at warp speed.

Even if the other party is a biological civilization, after all, once the level of civilization reaches the level of a fifth-level civilization, whether it is a biological civilization, a technological civilization or other civilizations, warp navigation is no longer a secret.

Although according to the detection of the previous detectors, the second blockade line has been the weakest time for their defense in recent times, but it must not be negligent, after all, the hidden means of biological civilization are definitely much higher than that of technological civilization, so if it is true that these biological warships are all hidden.

Then even with the current level of science and technology of the Ming Empire, it may not be able to detect the existence of the other party, unless the Ming Empire has been equipped with a space detection radar that is in the laboratory.

But it's a pity that Zhu Lei's main fleet is not equipped with a space detection radar, so once these spaceships are really hidden, it will be more difficult for Zhu Lei and them to vent than to ascend to the sky.

Finally, the fleet reached the front of the second blockade line, but just when Zhu Lei and the others were worried and afraid, the biological warships on the front blockade suddenly scattered in all directions, and did not attack Zhu Lei and his fleet at all.

This made Zhu Lei and all the personnel in the fleet very surprised, after all, although the spaceships above the blockade line were all fifth-level biological spaceships, and there were not many of them, but letting Zhu Lei and them enter like this was not in line with the habits of biological civilization at all.

However, although Zhu Lei and the others were very surprised, they were in a state of faster-than-light sailing. The speed was very fast, and in an instant, it passed through the second blockade and moved towards the third.

But when Zhu Lei and the others crossed the second blockade line, all the spaceships that had been scattered returned to their original state, and some biological spaceships were also sent to follow Zhu Lei and them.

When Zhu Lei and the others were only about half a light year away from the third blockade line, the fleet ended its warp sailing and began to enter normal space, this was because Zhu Lei and they had to jump out of the warp space, because the third blockade line was completely different from the first to second lanes in front.

The first and second blockade lines in front, although there are also a large number of spaceships, are only a small fleet at best, and they can't be compared with Zhu Lei's fleet at all.

But the third blockade line ahead is different, this blockade line has a huge number of biological warships, and the scale of the number far exceeds that of Zhu Lei's fleet.

However, Zhu Lei and the others are still confident that they can break through this blockade line, although the biological warships on the blockade line in front of them are obviously much larger than the biological warships on the first blockade line and the second blockade line, according to the division of biological civilization, most of the biological warships on this blockade line are fifth-level top-level space warships.

The largest of these biological warships has reached the level of tens of kilometers, which is already very remarkable for biological warships, after all, biological civilization is not like mechanical civilization, after all, biological civilization is not like mechanical civilization, and the warship of biological civilization is simply a living thing, so generally speaking, the size of the battleship of biological civilization is definitely much smaller than that of scientific and technological civilization.

Even some biological civilizations have reached the level of seventh-level civilization, but their biological warships still do not exceed 50 kilometers.

Moreover, the biological warships of the biological civilization are also much worse than the scientific and technological civilization in terms of combat effectiveness and defense, and the space warships of the same level are definitely dominated by the scientific and technological civilization, but when a large-scale war is fought, the outcome may not be determined.

Just like the blockade line in front of them, according to Zhu Lei's preliminary estimates, the number of biological warships on the third blockade line in front of him alone exceeded 50 million, and all the spaceships of Zhu Lei's entire fleet did not reach this number combined.
