For the plants on these planets, Zhao Zhongguo is naturally very clear, after all, when experimenting with these plants, he was also very concerned, and even at that time, he was severely shocked by the domineering of these plants, the planet occupied by such plants, even if the Ming Empire wants to get rid of it, it is very difficult, after all, these plants devour energy is too strong. So powerful that it can only be cleared with the ship's main cannon.

As a soldier of the Ming Empire, Zhao Zhongguo knew very well that there was no civilization in the entire galaxy that could be compared, and it was necessary to use pure physical strikes to destroy these plants.

And at this time, as a sixth-level biological civilization, they also vented Zhao Zhongguo's existence, after all, although the Ming Empire's technology is advanced, it still can't hide its own spaceship, not to mention that the civilization level of this foreign civilization is not low, although the other party is a biological civilization.

Although Zhao Zhongguo and their fleet have more than a thousand spaceships, it is obvious that the number of spaceships in their fleet is far from being comparable to the other party, although the fleet of this alien biological civilization sneaking up on the mine is only a small fleet, but there are tens of thousands of spaceships at least, but in comparison, the other party's biological civilization and their biological spaceships are much smaller than Zhao Zhongguo's spaceships.

When the sneak attack fleet of this biological civilization found that the fleet led by Zhao Zhongguo was coming, they did not turn around and leave, but saw that Zhao Zhongguo and their fleet were far inferior to them, so they immediately turned around and attacked Zhao Zhongguo and them.

After all, in the eyes of biological civilization, Zhao Zhongguo and the number of spaceships in their fleet are far inferior to them, although they have an advantage in the size of a single spaceship, but with such a huge number gap, it is no longer important that the size of the spaceship has a slight advantage.

However, the fleet of biological civilization did not develop any formation and any tactics, but all the spaceships rushed over in one go, in fact, this is also the characteristic of biological civilization warfare.

But what greeted them was a blow to the head, when Zhu Lei and they broke through the third blockade line, Zhu Lei and they had already fought with these biological civilizations, of course they knew the methods of war of these biological civilizations, so when these biological civilization warships began to charge, Zhao Zhongguo and they began to launch a large number of electromagnetic railguns, and sent countless space mines into the space in front of them, these space mines are all the latest space mines of the Ming Empire, and the intelligence level of these space mines is very high.

These space mines include a variety of new types of space bombs of the Ming Empire, including the earliest nuclear bombs owned by the Ming Empire, but unlike the previous nuclear bombs, these nuclear bombs are very powerful, and even the power of their explosion can directly destroy a medium-sized space warship made by the Ming Empire itself.

Of course, in addition to space nuclear mines, antimatter mines, quantum foam mines, and so on.

Moreover, Zhu Lei's main enemy in this globular star cluster is this alien biological civilization, so Zhao Zhongguo and the spaceships in their fleet are all specially designed to fight against biological civilizations.

These ships may not be very strong in terms of ship size and energy attack, and even the ship's protective shield is only the most basic.

However, these spaceships have been greatly strengthened in terms of physical attack and the protection of the spacecraft itself, and the artillery of pure physical strike methods such as electromagnetic railguns is even more than the number of capital ships of the Ming Empire, and the protection is not weaker than that of the capital ships.

Therefore, although the number of spaceships in this biological civilization fleet far exceeded the number of spaceships in Zhao Zhongguo's fleet, after the enemy fleet began to charge, these space mines in front of the spacecraft alone had already caused heavy losses to the fleet of biological civilizations.

And because these mines are specially designed for this alien civilization biological spaceship, so these mines have a very high destruction rate for the biological spaceship of biological civilization, basically no matter what kind of biological spaceship, as long as it is blown up by these space mines, it will either kill or be injured.

Therefore, the fleet of biological civilization has not rushed to Zhao Zhongguo and them, and the loss is as high as more than 2/3, seeing such a situation, the sneak attack fleet of biological civilization turned around and ran, after all, the fleet of biological civilization is not stupid, although they still have 1/3 of the very number at this time, but basically each of these biological spaceships is injured, and the combat effectiveness has greatly decreased, plus they know that the remaining fleet is not Zhao Zhongguo's opponent at all, so it is natural to retreat.

At this time, a similar scene happened in many places not far from them, of course, not all mines have biological civilization fleets waiting there for the Ming Empire fleet to annihilate them, in fact, there are not many situations like this, most of the biological civilization fleets leave immediately after sneaking up on these mines.

Although Zhao Zhongguo and the others wiped out most of the spaceships that came to attack the fleet this time, whether it was Zhao Zhongguo or Zhu Lei, they knew very well that such a fleet of tens of thousands was nothing to the enemy's biological civilization.

What's more, according to the information that Zhu Lei got from the Barabba civilization, these biological civilization spaceships were not the ships of the strongest biological civilization in the other party's biological civilization.

According to the summary of the news, these biological spaceships should belong to the subsidiary civilization of the strongest civilization of the other party, that is to say, the loss of these spaceships has no impact on the overall strength of the other party at all, and even the other party still wishes that the Ming Empire will wipe out their fleet.

After all, every river system is the same as the galaxy, and the subordinate civilizations are generally used as cannon fodder, after all, these have become the subsidiary civilizations of other civilizations, and their civilization level is not high, and there are many civilizations like this in each river system like the galaxy.

Just when Zhu Lei and the others eliminated a large number of biological civilization spaceships, at this time, the big river civilization that was hostile to them also got the news that many of the fleets that went to sneak attack the mine had been eliminated, and they also got Zhu Lei They specially developed a physical strike firepower enhanced fleet.

So they know that it is obvious that these fleets are specially built for them, after all, they also have some understanding of the war between scientific and technological civilizations, and the main means of attack in the direct war of scientific and technological civilizations is generally energy strike, and the energy strike method is not very efficient for their biological civilization, and even being able to exert 50% of the efficiency is already very high.

"Unexpectedly, the fleet of that civilization is much stronger than the intelligence shows, and the losses of those fleets that went to attack their mines at this time are very serious, basically more than 1/3, and even some of the borrowed teams are all wiped out, those civilizations are really some garbage, they can't contribute to our Big Magellanic Galaxy, and they still think about how to divide more resources every day, it's really wishful thinking, if you want resources, you must exchange them for war achievements."
