Almost reached 10% of the number of defenders on the defensive line.

Of course, it cannot be calculated this way.

After all, in the defensive battle at the passage entrance, the defenders have an absolute advantage.

Limited by the width of the passage, the attacking side cannot allow all warships to enter and arrive at the same time.

Take this third-class legion as an example. Each wave reaches 2,000 ships, which is already the limit.

At the same time, the defender can also set up a hemispherical defense line with the passage entrance as the center, and attack from all directions to form a super firepower network.

In the cold weapon age of the home planet, if you want to attack a city, you usually need several times the strength of the defenders.

But in the interstellar era, this kind of passage attack and defense battle...

I'm afraid it would take dozens of times the number of troops to make it possible.

After all, in the early stages, the attacking side was at an extreme disadvantage both in terms of numbers and position.

It will take a long time to rely on each wave of remaining battleships to slowly gather enough numbers to try to break through the defenders' defense line.

In fact, it is said to be a hundred times lighter.

Because the enemy is not only a fleet, but also a defense system, and even deploys various special means, etc.

Many times, the attacking side even needs to gather a hundred times more troops to be considered relatively safe.

Therefore, although this third-class legion has come out in fifty waves and one hundred thousand battleships.

But in fact, the number of warships that are still capable of fighting at this moment is only worth over ten thousand.

The rest...

Basically, they were destroyed the moment they came out of the passage.

But no matter what, the number has gradually accumulated to tens of thousands, hasn't it?

This also allows them to destroy more defenders on the defense line every time they counterattack.

After all, those United I-type battleships on the defense line...

But there is no space shield!

Just hit one ship and explode the other!

Although it can probably destroy thousands of combined battleships each time.

But this also made Luo Yu very heartbroken.

You know, he only has a total of 3 million Joint I-type warships in his hands.

Moreover, he still has to rely on these battleships to last until the pioneering fleet arrives.

"Let the 200,000 Joint Type II battleships enter the defense line immediately to enhance the firepower of the defense line!"

"Suppress the growth of the enemy's strength in the shortest possible time. Even if it cannot be completely suppressed, it will slow down its growth rate to the greatest extent!"

There was a hint of solemnity on his face.

Luo Yu said clearly.

It's not that he doesn't want to send more battleships up and suppress them with absolute firepower.

But this defense line is only so big. After all, it is just a passage that can pass 2,000 warships at the same time.

A hemispherical defense line is arranged around the entrance of the passage, ten light seconds away. Excluding the positions occupied by the defense systems, it can accommodate another 12.3 million battleships...

This is already the limit.
