After Lin Fei devoured the Extraterritorial Heavenly Demon and strengthened his own divine soul, it was equivalent to searching for the Extraterritorial Heavenly Demon, so naturally there was no secret that could be hidden from him. Pen & Fun & Pavilion www.biquge.info

The Extraterritorial Heavenly Demon comes from a large world called the Fahua Realm, which is more than a hundred light years away from the Five Seas Realm, and it is only possible to reach it by passing through more than ten spatial wormholes on the way, and the Extraterritorial Heavenly Demon is also because of his luck, when he has no way out, he happened to meet the Dragon Emperor, and he was able to appear in the Five Seas Realm.

Now, according to the memories of the Extraterritorial Heavenly Demons, Lin Fei was naturally able to return the same way and go to the Fahua Realm, and it was estimated that it would take about a year on the way.

Of course, this estimated time is based on the premise that the long-range space shuttle has been successfully refined.

Soon, Lin Fei came to the Five Seas Realm smoothly with the first batch of people who settled in the Five Seas Realm, including Fu Fengzi and other four god old monsters.

Fu Fengzi and the others came to the Five Seas Realm to break through the bottleneck of the gods with the help of the environment of the Five Seas Realm, as long as their strength can be stronger, the right to speak will naturally be heavier, and to provide a suitable cultivation place for the cultivators of the Kunlun Realm, that is also the content clearly stipulated in the alliance.

As long as there are enough resources and time to cultivate, I believe that it should not be a problem for Fu Fengzi and the others to break through the realm of transforming gods. Especially with the talent of Fu Fengzi, it is not impossible to be promoted to a Mahayana old monster even if he is promoted one day in the future.

It is precisely because of the great prospects that Fu Fengzi and other old monsters will become the help behind Lin Fei, and fully cooperate with Lin Fei to promote the cooperation between the two worlds.

However, after coming to the Five Seas Realm, Lin Fei didn't have much time to hang out with Fu Fengzi and the others, but directly entered the Iron Emperor Palace for retreat.

The purpose of Lin Fei's retreat this time was, of course, to refine the voyage-type cosmic shuttle, but he hadn't told anyone else for the time being, and it was a secret act.

Anyway, Lin Fei could control the Fire Spirit Iron Emperor, and if he wanted any heavenly and earthly treasures, he could supply them in the Five Seas Realm in a steady stream, and let Lin Fei try to test the degree. What's more, the Fire Spirit Iron Emperor also unreservedly helped Lin Fei to retreat together, which was enough to put Lin Fei's whimsical ideas into practice, and he was not afraid of wasting anyway.

There are two difficulties that are the most difficult to break through in refining the long-voyage type space shuttle, one is the thickness of the armor of the space shuttle, and the other is how to install the high-power space shuttle magic weapon on the space shuttle.

If you want to sail long distances, you must use the space wormhole in the universe, and when you travel through the space wormhole, due to the complete distortion of the three-dimensional space, you will be under great pressure in the wormhole, even if you are an old monster in the realm of transformation and integration, it is difficult to survive it with your physical body alone. Therefore, this requires the space shuttle to be equipped with extremely pressure-resistant armor, otherwise it will only crumble into the space wormhole.

If it is a large starship, as long as the armor is thickened desperately, it is estimated that it is not too much of a problem to withstand such pressure. However, in order to carry out a long voyage, it is impossible to completely sacrifice speed performance, and if you really have to keep thickening your armor, it will probably become a strange thing similar to a solid iron stone in the end.

Fortunately, after years of accumulation in the Five Seas Realm, there are a lot of special meteorites from outside the universe, and under the continuous attempts of Lin Fei and the Fire Spirit Iron Emperor, a special alloy was finally refined, which has an unimaginable ability to resist pressure, and finally successfully solved the armor problem of the long-range space shuttle.

Another problem is the device used to travel through space on the space shuttle.

If you want to sail far away in space, even if you can use the space wormhole to cross, but the space wormhole is not continuous, and there are extremely long distances between different space wormholes.

Some space wormholes that are far apart, the distance between each other is also calculated in light years, if you just rely on the speed of the space shuttle itself, I am afraid that Lin Fei's Shouyuan will not be able to reach the destination, so he can only use space shuttle to cross the space.

With the current starship technology of the Kunlun realm, the space shuttle device has been developed, but there is no doubt that it is a magic weapon that belongs to the category of giants, and it is naturally no problem to install it on planetary-level and stellar-level starships, but the space shuttle is impossible, even if it is the smallest model of space shuttle, it is more than ten times larger than the space shuttle!

In order to install the space shuttle device on the space shuttle, it is necessary to miniaturize this space magic weapon, and it must cross several generations at once.

Fortunately, Lin Fei and the Fire Spirit Iron Emperor were both refining masters, plus Lin Fei was a top expert in the miniaturization of magic weapons when he was researching nanoparticles, and he was also able to get the help of the Origin Fire, so he finally succeeded in miniaturizing the space shuttle device and successfully installed it on the cosmic shuttle.

Of course, although the miniaturization was successful this time, this space shuttle device did not have the possibility of mass production, and it must be refined by Lin Fei himself to succeed, but Lin Fei took this opportunity to guide a possibility for the way of refining, as long as the technology continues to develop, it is not impossible to mass-produce this small space shuttle device over time.

After solving the two major problems, it was very easy to refine the long-range cosmic shuttle, Lin Fei and the Fire Spirit Iron Emperor spent almost three months before and after, and a single cosmic shuttle that could travel long distances was finally completely refined, and Lin Fei could embark on a more distant journey at any time!

During the period of refining the voyage-type space shuttle, Lin Fei had already unknowingly spent his twentieth birthday, and to be able to have such an achievement at such an age, looking at all the worlds, I am afraid that there will be no second one.

At that moment, Lin Fei finished the retreat, received the refined Cosmic Shuttle into the Qiankun Ring, and broke through the barrier with the Fire Spirit Iron Emperor.

More than three months have passed, the run-in period of mutual cooperation between Kunlun and the five seas has passed, and now the five seas have changed greatly, with the help of relevant technical personnel in the Kunlun world, there have been more than ten production lines established in the five seas, and its efficient production efficiency has really subverted the thinking of many people in the five seas.

As for the Kunlun Realm, many strong people have easily made a breakthrough in the realm of cultivation after coming to the Five Seas Realm, especially Fu Fengzi has been in retreat until now, and it is very likely that when he breaks through, he will already be in the realm of integration.

The cooperation between the two worlds can indeed play a role in learning from each other's strengths, which is very beneficial to the two worlds, and it has made a good start for the cooperation between the two worlds!
