The construction of vellas is in full swing. Tens of millions of robots and a large number of experts are working hard on the planet.

On the planet orbit, dozens of small and medium-sized spacecraft production lines transported by Chris have been laid and put into production.

These production lines are civilian level, mainly used for the production of resource acquisition spacecraft. After all, it is impossible for the Federation to install jump engines for such spacecraft, and then transport them to Shanhaiguan.

In this case, the cost is too high. It's better to transport dozens of production lines directly and manufacture them in Shanhaiguan.

According to the plan, there are even production lines for killer whale Class Battleships in the last three batches of materials.

When Lin Fan wanted to die for the sake of great construction, Chris also took three legions to attack the city and pull out the stronghold. After all, these places have only 12000 local guard fleets. For Chris, it's a good choice to train the recruits of the fourth Legion.

As for the two Tianjun regiments, Tianjun was basically used to hold down the battle, and rarely made moves.

In this battle, Chris also used the latest wide area communication jamming device developed by the Federation for the first time.

In fact, this technology is very weak for high-level civilization, because it only works for the communication of low-level civilization, that is, the first to third level civilization.

When a civilization has mastered quantum communication, it is basically unable to interfere.

Therefore, the exchange price of this technology in the theo Federation is only 1000 points, which is basically free of charge, and few civilizations will exchange it at all.

Although it is totally useless technology for the other four civilizations, it is of great use to human beings. Especially for the plan of Lin Zhen and ED, the Federation must try its best to avoid exposing its real combat power!

Therefore, in the process of Chris' promotion, the defenders of the Republic of orr could not even send out a message, not to mention the incomplete message of Shanhaiguan.

It can be predicted that when Chris conquers all 38 star systems, the Republic of orr will still be unknown.

half a year later, the construction of Shanhaiguan has been completely on the right track, and three batches of resource collection spaceships, 300 in total, have been offline in the spaceship production line, and all of them have entered the working state. They will go to an asteroid belt in Shanhaiguan, and then they will continue to produce at the rate of one batch per month. After all, Shanhaiguan alone needs at least 5000 spaceships to basically meet the demand .

The mining robots have been deployed to the surrounding resource satellites for mining.

According to this progress, Shanhaiguan will be self-sufficient in about three years.

As for vellas, many buildings have been built in the ten sites selected by Lin fan, and gradually there is a trace of the city.

Of course, it will take several years before the ten mega cities are completely completed. At present, the infrastructure construction has just been completed.

And in some places with beautiful scenery, such as the seaside, hillside and so on, numerous villas have been built one after another!

These places are different from residential areas in cities. They are specially assigned to officers. That is to say, as long as you can reach the rank of lieutenant, you can apply for one.

For ordinary soldiers, they will be arranged in the residential areas of ten giant cities. Of course, both ordinary soldiers and officers will be provided with free housing.

In addition, on the track of Vilas, the star harbor group is also under construction with very high efficiency. The first batch of 1000 star harbors is expected to be completed in half a year.

All the things are going on in an orderly way.

On the other side, 8000 light-years away, the first wave of offensive launched by the IO Federation against the Sierra Empire has finally officially begun.

The first level Legion opened the way and directly defeated the defense line deployed by the Sierra Empire at the exit of Starway. Then the four second level legions followed up and soon swept the entire stellar system, completely destroying nearly 2 million warships of the Sierra empire.

However, the loss of IOF itself is very small, and mainly concentrated in the secondary Legion.

Among them, the first level Legion lost 6000 warships, and the second level Legion lost 80000 warships!

In the following six months, the other three attack fleets also arrived in the territory of the Sierra empire through the path of the stars, and quickly destroyed the defenders of the Sierra empire under the leadership of the first level Legion.

In only half a year, the Sierra empire lost four important border nodes and damaged 6 million warships!

You know, the main warships of the entire Sierra empire are only 9 million, and now there are no more than two-thirds of them. It's painful.

When the news reached Imran, the emperor of the Sierra empire was stunned for more than ten minutes!

Isn't it said that the babavi empire will solve the IO Federation? How can the IO Federation not only fail to solve it, but also launch a massive attack?

What's more, I don't know why my two royal fleets were paralyzed more than a year ago, and I have been wondering whether it was the hands of the babavi Empire, otherwise it doesn't make sense.I don't know why. In a word, after using the babavi Empire to deal with the IO Federation, everything that happened later seems to be off track, completely contrary to my own expectations.

If you look at the star map, Imran is a little scared.

As the Sierra Empire ceded ten star systems close to the side of the IO Federation, the IO Federation launched an offensive from the new border. The most recent route, only three star systems, could reach the capital circle of the Sierra empire.

There is no organized force to defend this route. After all, the remaining 3 million warships of the Sierra empire are scattered in the border areas.

Even if they can come back immediately now, they will not be able to arrive in less than ten years. Within this time, the Iow Federation has been directly attacking the capital circle for a long time.

According to Imran's calculation, the time left for him is less than five years, which is still under the premise that the IO Federation attacks through the way of the stars.

In fact, Imran was optimistic. After all, because he was afraid that the babavi empire was still under surveillance, the second legion of the Federation of human beings and the third legion of the queen of the Federation of IO had not been used!

Now, after confirming that the people of the babavi Empire did not stay behind to watch, the Iow Federation and human beings have decided to join these two armies to attack the Yellow Dragon.

A month later, 540000 warships of the United Fleet came directly to the capital circle of the Sierra empire. Originally, there were two royal fleets stationed in the capital circle, totally 240000 fourth generation civilized warships.

However, now the two royal legions are paralyzed in the fortress, completely unable to move.

The entire capital circle of the Sierra Empire has no resistance.

------

a month later, Loulan, the territory of the human Federation, will become the world's largest city.

After several years of fighting, the last fleet of the third Legion returned here, announcing the perfect end of the Loulan star cleaning operation.

Mankind has added 500 light-years of territory and thousands of star systems.
