In the face of the mechanical army that was waiting for the battle, the Zerg did not respond and launched an attack directly.

Seeing that the Zerg side started attacking without saying a word, Cheng Yuan and Zero could only launch a counterattack.

The Zerg still used the same tactics they had used to deal with the Crystal Spirits, and they sent out a large number of vanguard troops, which were very mobile and could carry biological soldiers to board the ship, which was the best test for them.

In terms of energy weapons, simple laser weapons are used to interfere on a small scale, so that these assault ships can reach the enemy ships smoothly.

He has a lot of research on the combat methods of the Zerg, and seeing that the other party did not use weapons of mass destruction at the first time, although he was a little puzzled in his heart, he still launched the energy barrier for the first time.

The golden barrier unfolded, and when the laser hit the barrier, it only created a small ripple, without any effect.

"The energy shield is pretty good. Leigh saw this and nodded appreciatively.

For his creation to be able to master the energy barrier technology, his inexplicable sense of relief broke out again.

"Look at ...... again"

Before he could say anything, the Vanguard had already crashed headlong into the energy barrier.

Clusters of dazzling firelight erupted, like fireworks, and Rang Li swallowed back the next words.

His eyes widened, with an expression of disbelief on his face, he felt that he was dazzled just now, the Pioneer ship should have been hit before it exploded!

Rubbing his eyes vigorously, he looked at the vanguard ships that crashed into the barrier one after another, and then exploded, and his face became gloomy for the first time.

“......”

"Very nice. After holding it for a long time, Li popped out these words from his mouth.

A barrier against energy and physical weapons, a technology that even the Zerg didn't have when he left.

It's not that they can't make it, it's that this kind of dual defense barrier, whether it's energy consumption, judgment mechanism, or the transformation of the protective layer, is not easy to solve.

It's not like they haven't invented that kind of energy barrier that can defend against any attack.

Although this barrier against kinetic and energy weapons is powerful, the problem is that while the barrier is deployed, they cannot send small vanguard ships to carry out surprise attacks.

This is a technique that refutes their overall tactics, and the adoption rate is extremely low!

It wasn't that I didn't think about putting this technology on the Starfortress at the beginning, but every time the spacecraft entered and exited the Starfortress, it needed to switch the energy barrier once.

Not to mention the huge waste of resources, it also makes things very cumbersome.

Eventually, this barrier technology was put into use in prisons.

This kind of place that only enters but does not leave, with this kind of barrier, they don't even need managers.

But he didn't expect to see this kind of technology again, and the other party was also very proficient in using it, looking at the small spaceships that came in and out of the other party.

Leigh instantly understood that the civilized race he had accidentally changed was now also a civilized race with powerful technology.

Thinking about this, Leigh's eyes also changed.

If I was interested in appreciating it before, now I'm getting a little more serious.

But he was a little puzzled, they obviously had a very powerful technology, why didn't they expand externally?

As an Overseer of a higher civilization, he had seen too many civilizations in the universe.

Among the civilizations he saw, almost all the races that had just entered the interstellar civilization were all plundering and exploring the outside world without any scruples.

I can't wait to expand my interstellar colony as much as possible.

It's not a sign of civilization's belligerence or madness, it's the need for resources that forces them to go on a crazy expansive quest!

But he couldn't understand the civilization in front of him.

When he arrived, he found that the galaxy was very inhospitable, with only a small and isolated galaxy, and other planets were basically not suitable for living organisms except for the target planet.

Although this small galaxy has two suitable planets, what can only be done with just two planets?

To put it bluntly, just two planets, not even a single interstellar fortress can be made!

It can be said that the poor jingle bell!

Could it be that this race thinks that there are no alien civilizations around it, so it is slacking off in terms of external expansion?

Just when he couldn't figure out why, the situation on the battlefield changed.

After fending off the Zerg's vanguard ship, Zero was also not to be outdone, and launched a swarm battleship to counterattack.

The dense small fighter crews formed a huge formation, and the fighters flying at sub-light speed were naturally unmatched in speed, and they rushed to the Zerg battleship group almost in the blink of an eye.

Then, with Leigh's stunned expression, he crashed into his battleship without hesitation.

The outer armor of the Zerg battleship is very hard, and even a small fighter with an energy shield cannot be directly destroyed, but is inlaid straight and straight on the surface of the Zerg battleship.

Leigh almost bit his tongue off when he saw this.

What happened in front of me looks so familiar!

"Could it be that when the genes were put in, even the genes of the Zerg were mixed in?" he muttered, and he couldn't help but have such thoughts in his heart.

This thought intensified when he saw the mechanized units pouring out of those fighters.

How similar to the way they fight the Zerg!

"Suan!" he couldn't help but contact his lieutenant.

And the moment he contacted Su An, his neural network was naturally connected to the neural network of the Zerg troops who were still in the Crystal Spirit Empire.

Zero has not relaxed its infiltration into the Zerg neural network.

After discovering that the neural network of the front line was connected, he did not hesitate to inject the virus he had developed.

He wants to perpetuate the connection between the two through clones mixed with the Zerg.

In this way, he had the opportunity to infiltrate the entire Zerg neural network through the war on the battlefield with the virus that Cheng Yuan gave him.

After confirming the connection between the two parties, Zero turned back to look at the robot that had already boarded the ship.

As soon as these robots appeared inside the Zerg battleship, they were surrounded by a group of Zerg soldiers with biological soldiers.

There is no nonsense on both sides, and after meeting they go straight to war.

Leo wants to see what difference this civilization has been transformed by them, and Zero's purpose is simpler, and he doesn't care about the loss of robots.

What he cares about is whether these robot soldiers can get enough nanovirus robots to mix in!

Whether it is an electronic virus or a biological virus, it needs to be transmitted through these nanoviral robots as a medium.

......

While paying attention to the battle between the two sides, Cheng Yuan also quietly controlled the embryonic creatures in the forbidden area of life to slowly come out of it.

Once there is a problem on Li's side, Su An, as an adjutant, will definitely put down the matter on Jingling's side and rush directly to Li's side.

What he has to do is to use these embryonic creatures to block Su An!
