In order to ensure that nothing went wrong, Lin Yifan asked the Xingsheng to be fully prepared before allowing Princess Ziyang to go.

The Prosperity decided to first upgrade the Warframe's Warframe and Combat Mecha once, then add Elemental Cannons to the Sea Spirit Battleship, and secondly, install two sets of manufacturing lines in the small flagship.

With the manufacturing line, Princess Ziyang and the others can create weapons and equipment for the Destroyer fleet and warriors over there.

Anyway, except for battleships and drone carriers, all other conventional equipment can be manufactured, and they are manufactured in large quantities.

Two sets of god-level assembly lines are enough to support a big battle. The big deal is that it just consumes materials, as long as there are no casualties, it's easy to say.

Lin Yifan was very concerned about the safety of Princess Ziyang, and he asked several generals to lead ten small flagships and supporting capital warships and drone carriers.

Of course, the replica version of the Ice Phoenix Battleship must be indispensable. Not only can the Ice Phoenix Battleship use teleportation tactics, but it is also an escape artifact.

The Xingsheng mobilized all the logistics forces in the base and prepared to complete this upgrade mission in the shortest possible time.

The Prosperity was worried that there would be danger on the side of the Crystal Stone Guard, and he was afraid that the Guardian Civilization would be killed, after all, there was only one Crystal Stone Guard, and it was difficult to protect them when facing the siege of many enemies.

In fact, Lin Yifan was very worried that if there was a problem with the crystal stones in the Dapeng River system, there might be the same problem with the crystal stones in other places.

Maybe those hostile forces didn't find the coordinates of other crystal stones, but Lin Yifan didn't dare to guarantee this.

The crystal stone is the key to overthrowing the hegemonic power, and Lin Yifan will never allow the crystal stone to fall into the hands of the enemy.

Even if he is really robbed by the enemy, he has to snatch it back strongly. Now Princess Ziyang's task is very important, after finding the sixth crystal stone, Lin Yifan can analyze the more advanced flagship manufacturing technology.

Only by perfecting the manufacturing technology of the flagship can it confront the hegemonic forces. The regular fleet, in the face of flagship formations, can only be the presence of cannon fodder.

After the sixth crystal stone is found, it can also analyze high-level space technology, which will make Lin Yifan's troops even more elusive, and the distance of the teleportation array can also be increased by several times.

At the same time, with the sixth crystal stone, the strength of the special sensor will be increased by dozens of times, and it will be much easier to search for other crystal stones.

It took two months for all the upgrade tasks to be completed, and during these two months, Princess Ziyang and several other generals were not idle.

In order to face unknown dangers, they are strengthening their training and mastering more scientific knowledge.

The Xingsheng was worried that the crystal stone would change positions again, and he couldn't wait for these two months in vain.

On its way back to base that day, the Prosperity used the teleportation array to teleport the tracker over.

The places where Lin Yifan and Princess Ziyang went were very far away, and they needed to teleport twice in the teleportation array.

To this end, prior to the operation, Tis conducted a detailed reconnaissance of the first teleportation site.

She discovered that there was an asteroid belt near the teleportation point, and used the teleportation array to build a small base there and installed a new teleportation array to facilitate a second teleportation.

The Prosperity also followed the example of Ties, and also found a suitable place to set up a base at the first teleportation point, and then installed a new teleportation array.

Both bases are camouflaged and equipped with state-of-the-art anti-scanning devices, as well as supporting defense systems.

These two teleportation points are very critical, and they are important conditions for Lin Yifan, Princess Ziyang and the others to return.

Tis and the Prosperity will never put this base in danger, and there are dedicated people and intelligent systems to keep an eye on everything there.

As long as there is an abnormality in the surroundings, the base will send heavy troops to defend it as soon as possible. Otherwise, if the teleportation point was destroyed by the enemy, it would be difficult for Lin Yifan and them to come back.

Two months passed quickly, and the Xingsheng was ready. At this point, all the fleets were floating in the orbit of the planet, and then a curtain of light enveloped the fleet.

The next moment, all the fleets disappeared in place, appearing at the first waypoint. The first thing to do when you land is to explore the surrounding environment in detail, and then leave a number of combat mechs and engineering robots in the base.

Princess Celestial's fleet will stay here for two days, and after two days they will teleport a second time, with the target river system called Sun Constellation.

At the same time, on Lin Yifan's side. They had already completed the work of perfecting the waypoint, and now the fleet had teleported to the second target.

The river system that Lin Yifan went to is called Kunpeng Constellation. This constellation is very large, much larger than the Roc River system.

Because the volume of the Kunpeng River system is too large, Lin Yifan launched a large number of probes at the first time.

With space technology, Lin Yifan can teleport the teleporter to any location in the Kunpeng River system.

He had to get to grips with the situation in this river system as soon as possible so that he could find his people.

Of course, the first thing you do when you come here is to build a base. He can't run around the world with his fleet, which will definitely cause panic among the local civilizations and cause unnecessary trouble for himself.

The large army must find a place to hide, and there are many things to be done to build the base, which cannot be completed in a day or two.

Anyway, now that the probe has been launched, Lin Yifan is not in a hurry. There may also be strong enemies here, and Lin Yifan must prepare in advance.

In order not to attract the attention of the local civilization, Lin Yifan chose to teleport at the edge of the river system every time.

However, the resource planets here are also relatively scarce, and it is difficult to find a suitable star field to build a base here.

The fleet is docked in the orbit of a barren planet, and Tees unleashes a large number of engineering boats to gather minerals nearby.

Three days later, the probe sent back a message that ten light-years away, there was a star system suitable for a base to build.

The reason why the base was chosen here is because of the harsh environment within this star system. For the forces in general, their fleets simply cannot come close.

And for Lin Yifan, who has mastered space technology, it is easy to teleport the fleet to the interior of the star system.

The first to enter is the engineering boat, which is loaded with a large number of engineering robots, which are responsible for the preliminary construction of the base.

Teess used nanotechnology to speed up the construction of the base, and in less than two days, the base has been preliminarily completed, and now the installation of the teleportation array, which is a very critical device.
