Catherine's scalp was numb at the moment.

What the curvature engine represents, he is well aware that on the entire Orion arm, only one civilization has mastered this technology.

That is the only fourth-level civilization, the Babawi Empire.

To say that the current Human Federation is a curvature engine purchased from the Babawi Empire, Catherine believes that this is absolutely impossible, because this technology is forbidden to be sold in the Babawi Empire.

Then the problem arises, after eliminating all the impossibilities, it seems that there is only one possible situation left, and that is...

------

More than 10 million kilometers behind the garrison fleet, the Third Legion of the Io Federation is galloping through the void.

At this time, Alfi also received the latest report from the garrison fleet, but this content really surprised him a little.

The other party actually destroyed the Oaks Empire and saved a large number of captured angels on the Oaks star?

This time it was specifically to escort these angels home? Do you want to be so friendly? When did you say that there was so much love in the universe?

It's no wonder that Elfi thinks so, after all, in this jungle-like universe, war between civilizations is the main theme, the law of the jungle is the foundation of everything, and peaceful coexistence and hand in hand are non-existent, okay!

Of course, if it weren't for the fact that the Io Federation is an angel clan and has been detected to be able to reproduce with humans without barriers, the Federation would not be doing what it is now.

So, in essence, Elfi's idea is still not wrong.

And what surprised Catherine the most was that the opposing fleet was highly likely to have a curvature engine.

If this is true, then the matter is a big deal, this is most likely an unexposed native fourth-level civilization, or a fourth-level civilization from outside Orion?

Either way, it's not something that the Io Federation can afford to offend.

"How long do we have to get there?"

"It's currently 12 million kilometers away, and it can be reached in about 40 minutes!"

"Okay, tell Commander Catherine, hold the other party steady, and we'll talk about it when we get there!"

"Yes, Captain Elfi!"

Inside the bridge of the Ouranos, Lin Fan looked at Catherine with a pale face, knowing that she had reacted to the key point and was ready to continue to add fire!

"Liang Xue, order a battle cruiser to fire its main guns at us!"

"Yes, Commander!"

Half a minute later, Catherine received a report from her subordinates that a battleship in the opposing fleet was being recharged.

Catherine was a little nervous about this, not knowing what the other party was going to do, until the next moment...

A battle cruiser not far from the Ouranos fired a cannon-level ion beam that bombarded the Ouranos directly.

This attack directly stunned Catherine, what are humans doing?

However, the ensuing scene made his eyes widen and his face was incredulous.

The ion beam at the main cannon level did not pose a threat to the Ouranos, and a light blue energy shield appeared in front of everyone's eyes, easily resisting the attack, and not even leaving a trace of waves on the shield.

At this moment, Catherine finally understood what Lin Fan said before.

If we have malicious intentions, can your 1,000 warships and the 300,000 warships that are rushing behind us stop us?

That's right, this is an energy shield, if the other party is really malicious, do you need to talk so much to yourself? You can completely push yourself sideways!

And the energy shield plus the curvature engine, what does this represent? This is a fourth-level civilization!

Even if it is not, it must be half a foot that has already stepped into the fourth-level civilization, and the third-level civilization is nothing in front of it, no wonder the other party directly and easily destroyed the Oaks Empire, and now all this has a reasonable explanation.

Catherine, who figured it out, immediately passed the information on to the Third Legion.

------

"Commander Elfi, Commander Catherine has the latest information, it's a video material!"

"Huh? Play it out and see! ”

"Yes!"

A projection screen immediately appeared in the bridge, and the video from Catherine was played, which was the scene where Lin Fan showed the energy shield just now.

After seeing it, Alfi's scalp was numb.

Energy Shield? Coupled with the curvature engine reported by Catherine before, is this really a fourth-level civilization?

In this regard, Alfi did not dare to slack off, but he knew what the result of angering a fourth-level civilization would be, it would inevitably be the death of the people and the extinction of the race, and there was no other possibility.

A fourth-level civilization saved his own people, and specially sent a fleet to send him back, but he treated the other party as an enemy, isn't this looking for death?

This matter is no longer something that can be handled by herself, and the queen must be left to decide as soon as possible.

"Inform Commander Catherine that you must not make any rude acts, and I will personally visit the opposing warship later!"

"Yes, Commander Elfi!"

------

Planet Io, in the Hall of Angels, Queen Bella was frowning at the leaders of the various tribes in front of her.

In the Io Federation, don't think that calling the queen is an imperial civilization.

The queen also has a term, but the angel queen each term is up to 1,000 years, and after the term ends, it is not her own daughter who takes over, but re-elects a new queen.

"Queen, Commander Elfi has an update!"

A guard walked into the room and reported to Bella.

"What did Elfi say?"

"The other party is suspected to be a fourth-level civilization, and it has been confirmed that it has a curvature engine and energy shield, and the other party has no obvious malice, in order to show respect, I will personally visit the other party's flagship."

After the guard's words fell, the whole room exploded.

The faces of the eighteen clan leaders turned pale all of a sudden, fourth-level civilization? Are you sure it's not a joke?

Isn't there only a fourth-level civilization like the Babawi Empire on Orion's arm? When did another one pop up?

What are they here for?

"Everyone, be quiet!"

Looking at the clan leaders whispering below, Bella also had to stop it.

"First of all, the fact that the other party has the curvature engine and energy shield has been confirmed, and secondly, the other party should have no malicious intentions as Captain Elfi said, otherwise it can directly push us sideways, and there is no need to do so many things."

In response to what the queen said, the tribal leaders also nodded one after another.

What the queen said is not wrong, if the other party is really malicious, there is no need to do this at all, just push it sideways and it's over.

After all, it is too simple for a fourth-level civilization to destroy a third-level civilization, and there is no need to talk nonsense with you at all.

Seeing that there were no objections from the people below, Bella continued.

"In that case, then according to what Captain Elfi said, she will personally visit the other party's flagship and confirm the other party's intentions first!"
