It has been nearly five years since the end of the battle of Wayne.

Four years ago, Imran, the emperor of the Sierra Empire, sent a message asking for a peace agreement with the Federation of IO and willing to cede ten star systems close to the Federation of Io. Queen Elfi immediately agreed to this request.

In fact, both angels and humans didn't want to agree at first, but later they learned from basil that there were two royal fleets and more than 4 million warships in the sera empire. Considering that they could win each other with their strength at that time, but their own losses were not small, they finally agreed.

After all, time is on the side of human beings and angels. As long as there is three or five years, the strength of human beings and angels can be doubled. At that time, the destruction of the sera empire can be achieved at a very low cost. There is no need to be forced at that time.

Taking advantage of these years, the IO Federation not only completed the establishment of the first regiment of the Queen's guards, but also established the second and third regiments of the Queen's guards with the support of mankind.

At present, there are three quasi class IV warships in the army, and the number of warships is as high as 900000.

In addition to the Queen's close guard fleet, the IOF also refitted a number of ordinary fleets, only installed the shield system, but not the transition system, which was only used for the defense of the way of the border node star.

At present, there are four modified fleets stationed at four nodes on the latest border between the IO Federation and the Sierra empire.

It has to be said that in the past four years, the IOF has moved very quickly. In particular, the development of warship manufacturing industry is amazing. It is worthy of being an old class III civilization.

At this moment, a fleet out of the transition state, appeared in the IO federal capital circle.

This is the seventh fleet of the second legion of the Federation of mankind. This time, the mission of the Federation of IO is to escort Bella and her son.

Speaking of Bella, the last queen of IO Federation has been away from the Federation for ten years. Now even Lin Tian is nine years old, so she specially discussed with Lin Zhen and wanted to take Lin Tian to IO Federation.

To this, Lin Zhen nature won't refuse, even let Liang Xingchen arrange a fleet to escort.

When she finally returned to IO, Bella was also very emotional. She never thought that a visit would stay on the earth, and even made a couple with Lin Zhen.

Now think about it, it seems that the guy bullied himself and didn't know anything, so he cheated him. Now that he has rich knowledge, it's incredible to think about himself.

The most exaggerated thing is that I even said to Lin fan that I would like to ask him to have a baby. Now I think it's a shame.

Through the porthole, looking at Io star getting closer and closer, Bella also pulls Lin Tian to say to him.

"This is where mom was born!"

"Mom, why is this planet green?"

Lin Tian pointed to the growing IO star in front of him and asked Bella.

Unlike the earth, the earth's ocean accounts for more than half of the whole planet, while the ocean area of IO is relatively small, accounting for only about 20%.

The most important thing is that IO, as the capital star of the Federation, basically has no industrial equipment on it. It has a good idea of nature conservation. The whole planet is covered with thick vegetation and tropical jungle can be seen everywhere.

Coupled with the refraction of light and many other reasons, the whole IO seems to be emitting green light.

"This is because the environment is different. You will learn it when you go to middle school!"

Bella said with a smile.

When the mother and son looked at Io, unexpected guests came!

Just about 5 million kilometers away from the seventh fleet, the void suddenly contracted, and a strange fleet, about 1200 ships, appeared.

Suddenly, the alarm rang throughout the seventh fleet, bridge, army commander Scott is very clear, this is the jump engine!

However, among the Orion arms, besides human beings and angels, are the subsidiary civilizations of human beings and the babavi empire.

But after comparison, there is no record in the shape database of these spaceships, so the answer is obvious. It is likely to be a fleet of babavi empire.

"Commander Scott, what's the matter?"

At this time, Bella also took Lin Tian to the bridge and asked Scott.

"First lady Bella, a fleet suddenly appeared not far away from us, and still came here through the jump engine."

Scott said as he controlled the projection of the observed fleet image.

The moment Bella saw it, her eyes suddenly shrank. She had the impression that she had seen this fleet once decades ago.

"This is the fleet of the babavi Empire, but it's not their combat fleet, it's a fleet of star traders!"

"Star merchant?"

Scott had some doubts. After all, human beings don't have such a profession."Yes, it's the kind of businessman who runs around on the Orion Arm, doing business with all civilizations!"

Listening to Bella's words, Scott breathed a sigh of relief, but then he remembered something and frowned again.

Even businessmen can't expose themselves, otherwise the news will reach the ears of the babavi empire.

"First lady Bella, at present, we can't expose ourselves too much to the eyes of the babavi empire. If you want to get angry with queen Alfie, just pretend that we are an ordinary third class civilization fleet!"

Scott thought for a moment and said to Bella.

"OK, I'll contact Alfie to talk about the situation!"

Then Bella picked up the messenger and contacted Alfie.

And five million kilometers away, on the flagship of babavi's imperial caravan, babavil was also observing the fleet which was obviously not the Federation of Io.

"Lord babavile, we found that this fleet is different from any known civilization through database comparison! There are no records in our database! "

Babaville was a little bit suspicious after listening to his men's report.

Looking at the observed images, the formation of this fleet is very similar to that of the babavi Empire, that is, a unified type of ships, which is also a symbol of the fourth level civilization.

After all, with energy shields and jump engines, there is no point in having more than one type of ship. Only civilizations below level 4 will use more than one type of ship to cooperate in combat.

Isn't this the mysterious fourth level civilization that Imran talked about so coincidentally?

"Record everything of this fleet in detail, all scanning methods that can be used take turns, and record all data into the database."

"Yes
