From Xu Yuan's introduction, Xu Fei finally understood everything, when he was on the far side of the moon, he didn't expect that the energy wave of the powerful thunder tribulation was discovered by the Arabalans hundreds of light years away;

They sent warships to arrive, originally wanting to occupy the earth, but found that although the weapons of the Japanese army on the earth were relatively backward, they could have many attack power and attack methods, so they were ready to take away the little devil they had chosen;

When the establishment of the space gate had just diverted the little devils, the space-based kinetic energy weapons of the Japanese army penetrated their energy shield and destroyed their warship, and the Japanese army obtained advanced technology from the broken warships of the Arabarans, which continued to develop in the following decades;

Establish a lunar base, immigrate to the moon and space, and then highlight the solar system and the Galactic Bantana Alliance, the two sides hit it off, and the high-level Japanese army who has established the Chinese Federation has joined the alliance and is ready to fight against the Kaba Empire;

In the first two or three hundred years, the Japanese army developed rapidly, the population of the Chinese Federation exceeded 100 billion, eight life planets were found within the diameter of 50 light years divided by the alliance, no less than 3,000 large-scale industrial planets were developed, and as many as 1,000 colonial satellites were established in space;

When China joined the alliance, countries that had been dragged down such as Europe and the United States began to unite and re-develop their science and technology;

After the Huaxia Federation has become an interstellar country, their spaceship has finally flown out of the solar system, and they have also joined the alliance, and now they have established the European and American Federation in the star field next to the Huaxia Federation;

But they still regard the Earth as their capital, and that's it. The two interstellar nations jointly use the earth as their capital, which is also a strange thing in the interstellar world.

The Exterminator now has ten starfleets, in addition to the Venus fleet in the solar system. The rest of the fleets are all scattered on the borders of the Huaxia Federation Territory, because space is the most difficult to defend, which makes Huaxia, which has not been in the interstellar development for a long time, very headache.

Just when Xu Fei was thinking about how to completely destroy the little devils and block the continued development of the Mosa Empire in China, Xu Ling'er, who had been tinkering with the system, suddenly said loudly:

"My husband's brother's system exchange function and promotion function have been launched, and it is actually interstellar items that occupy the main one, and now you are the peak of human immortals, and you can exchange a lot of things;

Everything from the basic laser cannon to the starfortress can be redeemed, alas. It's just that the price is high, it's really high;

You eliminated a devil's star destroyer before, and wow, the price is also high, alas. 500,000 merit points, which is equivalent to the previous 5 billion merit points. ”

Xu Fei only had less than five million merit points in his hands at this time, so he received 500,000 merit points again, which was also good news. Xu Fei asked Xu Yuan's projection to wait for a while. He directly threw his divine consciousness into the virtual system and looked at it.

The laser gun is only one merit value, and the laser cannon is only three merit points, but just like the price of fighting the enemy, a standard mass-produced mecha is worth 800,000, a captain is worth 1 million, and the God of War mecha is 3 million;

And the standard space destroyer is only 500,000 merit points, the large battleship is only 2.5 million merit points, and the interstellar counterattack platform is worth only 15 million. There are only 30 million Star Fortresses;

Of course, the number of exchanges provided in the system is the same as before, divided according to the standard. The above products are actually divided into 100 years, 1,000 years, 10,000 years and 20,000 years span technology products, the equipment after 20,000 years is far different from the product value of 100 years, Xu Fei saw that it was drooling;

However, he also looked at those equipment, although the God of War mecha spanned 20,000 years, the materials used were far inferior to his current infinite free materials, but the operating system and weapon system on it became more detailed and flexible, and the external radar and surveillance systems were incredibly advanced.

He finally took a look at the merit points he needed to upgrade the Earth Immortals, 100 million merit points, which was equivalent to ten times the previous upgrade Mahayana Ascension, so that the subsequent upgrade system was also ten times higher.

"Xu Yuan, is the current scientific research institute still under your control?" Xu Fei said in a deep voice after studying his exchange system.

Xu Yuan nodded and said:

"At the beginning, in order to prevent the scientific research institute and the special combat team from being controlled by the government, I confirmed when setting up the system terminal that no one can interfere with the research and combat plan of the scientific research institute and the special combat team, otherwise it will be recognized as treason;

At least all the top levels of the government and the military ministries that have changed over the past few hundred years have understood this, and they have been working diligently and have not tried to seek absolute power. ”

Xu Fei touched his chin and thought for a moment, since he returned to the Earth Universe, why not continue to promote Huaxia's great leap again, if he wants to find a suitable immortal cultivation object, it is not an easy thing, maybe when he cultivates to the time when the Great Luo Golden Immortal reaches the Flying Ascension Earth Immortal Realm, he does not have a suitable object yet.

Looking at Xu Yuan, who only had one brain left, Xu Fei said in a deep voice:

"Wait a minute, I'll reopen a large space underground, and by the way, set the passage mouth in the sea, I'll give you a future mecha, you are responsible for studying all his designs and systems, where will I put infinite freedom, you give me to modify it according to the settings of the future mecha, it's a loss to fight without an energy shield and phase transfer coating."

Also, I will give you a battleship with the role of a space aircraft carrier, step up to learn the above data parameters, we will produce those equipment in large quantities in the future, I don't believe that even if little Japan sacrifices chrysanthemums to aliens, their technology can be 20,000 years ahead of us. ”

Xu Yuan's loyalty to Xu Fei is undoubted, even if he only has one brain left, he will never betray Xu Fei, Xu Fei can definitely trust him.

Take out three million merit points worth exchanging equipment, so that Huaxia's technology will leapfrog again, whether it is an earth war or an interstellar war, Xu Fei's goal will always be that the Yanhuang nation is all over the infinite starry sky.

"Okay, Commander, I will immediately mobilize the best scientific researchers for development, and recycle the main mecha group of the special combat team to the lunar range, the Japanese army is preparing to attack the Huaxia Federation from the solar system, in addition to revenge, I think they also hate the destruction of the Japanese army to the core, and even have a grudge against the entire earth." Xu Yuan said with a smile.

Xu Fei was silent for a while, looked at Xu Yuan's brain trembling slightly in the incubator and said:

"Maybe it won't be long before I have a way to bring you back to life, and you can reset the main system when you're fine."

"Resurrection, well, the commander should be able to do it, I think I can learn a lot about the computer system while learning about the new mechs and battleships." Xu Yuan's virtual human body nodded and said.

Xu Fei's body shook in the computer room, and his body directly escaped below 4,500 meters, he summoned the true fire of the sun, almost in seconds, a huge space about two thousand meters high, long and wide, and fifteen kilometers wide, Xu Fei instantly exchanged hundreds of millions of tons of overall special material guards and columns to fix this space;

After completing the underground research space, Xu Fei burned a huge passage all the way to the bottom of the Bohai Sea, of course, he did not penetrate the bottom of the sea for the time being, it was because they needed a new type of battleship to build a few before they would leave from here.

Turning around, Xu Fei connected to Xu Yuan's spirit wave, and under Xu Yuan's guidance, he connected a passage where he could take an underground train, which was the first step for him to complete the new secret research institute for destroying the Japanese army.

Swapping out the extremely excellent mecha and battleship at a glance, Xu Fei asked Xu Yuan to start mobilizing people to control here, he was unwilling to directly expose himself to the outside, this time he was ready to let go of the once highest position of the commander of the Japanese army, and secretly intervene in the war between Huaxia and any enemy.

After doing all this, Xu Fei and Xu Yuan chatted about the development of the earth and the pace of Huaxia's entry into the universe over the years, because of Xu Yuan's existence, Xu Fei had a new identity certificate, and he also got a villa that belonged to the scientific research institute near the scientific research institute, which contained almost everything.

When Yingkou entered the middle of the night, Xu Fei lazily lay on the roof of the villa and looked at the starry sky, but his thoughts were ethereal, thinking of his wife and children and two doppelgangers who didn't know what world he had entered (to be continued......
