With the strong cooperation of Lingxumen, the Lingxu Science and Technology City jointly built by Mochizuki Science and Technology City and Lingxumen was successfully built in only three years.

It was a megacity covering an area of thousands of square kilometers, and it also had a Spirit Gathering Array to attract casual cultivators to join.

Except for those technologies that do not have the Ministry of Armed Forces, the rest of the science and technology are shared with them free of charge.

After all, Zhong Yuan didn't rely on that to make money, and using them to help him earn merit was what he cared about the most.

The overall strength of Lingxumen is much stronger than that of Mochizuki Science and Technology City, and their efficiency is even higher than that of Mochizuki Science and Technology City, which has given them a lot of processing plants, production lines, and a lot of skilled workers and teachers.

Soon their production level reached a high level, and the number of workers was in the millions.

Gu Xiyuan didn't care too much about this matter, but he was not stingy in terms of people and things.

He also wanted to accumulate some merit.

Although there is no hope of impacting the Heavenly Immortal Realm yet, what if?

Impacting the Heavenly Immortal Realm and surviving the Heavenly Immortal Tribulation requires a lot of merit protection, and it is also a good thing to be able to take some merit now, and it doesn't cost much.

Even if you calculate it, you will still have to earn after a long time, and it is not impossible to earn back those billion spirit stones.

As the city lord of Lingxu Science and Technology City, he let a peak cultivator who had no possibility of advancing to preside over it.

For an old monk like this, there is no possibility of advancing in cultivation, but his mind has settled down, and he is more interested in making meritorious deeds.

That monk was more than willing to take on the position of the lord of the city, and to advance science and technology in this area of Zhiguo for the benefit of mankind.

Under his auspices, the scientific and technological achievements of Lingxu Science and Technology City have expanded outward at a very fast speed, although it has not yet reached the point of docking the radiation range of other science and technology cities, but at this speed, with the backing of Lingxumen, it will probably not take a hundred years to allow the entire Zhiguo and other ordinary people to enjoy the convenience of science and technology.

The backstage of Mochizuki Science and Technology City is not as strong as that of Lingxu Science and Technology City, and there are not so many monks' power to mobilize, so in terms of science and technology promotion, it is not as fast as Lingxu Technology.

However, in the development of cutting-edge science and technology, after integrating into the Xiuzhen civilization, it has entered a relatively high level.

Two days before Zhong Yuan left the customs, the Armed Forces Department of Mochizuki Science and Technology City conducted a missile test launch, this time it was the sixty-seventh missile test launch after the large number of refiners from the Thousand Machine Pavilion joined.

A large number of runes are added to the refining process of the missile, and very precious materials are used to ensure that they are not burned out during high-speed movement, and the positioning system is also very accurate, and it also has the function of automatic correction.

This time the test launch reached a range of 50,000 kilometers, and the speed reached an astonishing 100 times the speed of sound.

A hundred times the speed of sound, that is, a distance of 50,000 kilometers, can be reached in about half an hour.

With such a fast speed, there was not much time left for the monk to react.

It's not enough to deal with the Returning Monk, but it's already very effective against the Avatar Monk.

The average Returning Void Cultivator's Divine Sense sensing distance is about 1,000 kilometers, that is, about 2,000 miles, and at this speed, after sensing the crisis, the reaction time left for him is about thirty seconds.

This time is enough for them to move to a safe place.

The distance of the monk's divine sense is about five or six thousand miles, and the chance of avoiding danger is even greater.

However, the Divine Transformation Cultivator, even if he is at the peak of the Transformation of the Divine Consciousness, has not cultivated a special method of improving his divine consciousness, and the distance of his divine sense sensing will not exceed five hundred miles, and the time to be able to react is too short, just a few seconds.

And their transfer speed is far less than that of the Returning Monks.

If the missile carries a nuclear warhead with a high explosive yield, it is possible that they will be reduced to ashes.

And the accuracy of this missile's hit has reached within 100 meters.

This is already a very remarkable breakthrough.

This is not the limit of their technology, they once test-fired a super long-range missile, which flew an astonishing million kilometers and was very fast.

At that time, Zhong Yuan happened to be out of the customs, and after hearing the news, he was very surprised: "Why are you shooting so far? Is it necessary? Who are we going to deal with when we come up with a missile with such a long range?"

These words made those people stunned.

Who is it used to hit at such a distance?

Even if it is a Returning Void Cultivator, the distance of divine sense sensing is only a few thousand miles, and there is no need to fight each other from a distance of millions of kilometers.

And it can't be hit at all.

The longer the range, the higher the requirements for the material, and the lower the accuracy, which is completely unnecessary.

They only pursue the limits of technology, but forget about practicality.

So in the end, Zhong Yuan asked them to study those missiles with a range of 5,000 to 50,000 kilometers to enhance accuracy and speed.

Why did he go to 50,000 kilometers, it was because Zhong Yuan felt that there might be an existence in this world where the divine sense sensing distance could reach tens of thousands of miles.

Just like that time when he assassinated Luo Ning, he was obviously tens of thousands of miles away from Luo Ning, but the Kunpeng that suddenly appeared found him, if he hadn't escaped with the Eight Poles Disc, he would probably have died at the hands of that Kunpeng.

After thinking about it, it is safer to be separated by a distance of 50,000 kilometers.

The distance of divine consciousness sensing is 100,000 li, which can only be achieved by the Heavenly Immortal Realm, and there should be no such ruthless people in this world.

They also didn't insist on dealing with the Returning Monks, because they found it too difficult to kill the Returning Monks with nuclear missiles.

Unless the Monk sat still, it would have been impossible to kill him.

They are also researching laser weapons, which Zhong Yuan brought back last time in the technical data.

To what extent has the laser weapons on the earth developed and have a certain combat effectiveness.

However, the lethality of laser irradiation to monks is very limited, and although it is very fast, it is basically impossible to accurately irradiate a person at a very long distance.

Of course, if a person with a strong divine sense like Zhong Yuan took a super-large laser weapon and irradiated it at the enemy from a distance of tens of thousands of miles, he would indeed be able to hit the enemy.

The distance of tens of thousands of miles, for the laser, does not need a second, a fraction of a second is enough, and no monk can react so fast.

However, the lethality of the current laser weapon is still very limited, and the power is not strong enough, even the Jindan monk can't help it with a short period of irradiation, let alone the monk who returns to the void.

This weapon looks lofty, but at the moment it is not as useful as a nuclear missile for monks.

At least the nuclear missiles are already effective against the Avatar Monks.

Of course, development is to be developed, and perhaps one day we will be able to make a laser weapon that is quite powerful enough to kill the Monks of Resurrection.

More advanced weapons, such as antimatter weapons, are also being studied.

However, after years of research, the existence of antimatter has been discovered, but how to capture those antimatter and how to make it into weapons has not been studied.

What has not been studied on Earth for so many years, it is not so easy to study here.

In addition, nuclear bomb tests have been carried out seven or eight times in the past few years, and each time it has been a big breakthrough.

In a recent nuclear test, the explosive yield was equivalent to 10 million tons of high explosives, and that kind of power made the faces of the monks who participated in the test change their faces drastically.

They still have ideas to develop nuclear ejections on the scale of hundreds of millions of tons or even billions of tons.

The earth has carried out hundreds of millions of tons of hydrogen bomb explosion experiments several decades ago, and there is not much technical difficulty, they just want to test the destructive power of nuclear bombs of different yields, so as to obtain a data suitable for them to develop weapons.

What level of monks to deal with, what level of warhead to use, this requires relatively accurate data.

After Zhong Yuan came out of the customs this time, he was more satisfied with the progress he heard.

He urged those scientific researchers in the Ministry of Armed Forces to continue to step up their research on nuclear weapons and strive to produce several billion-ton or even 10-billion-ton warheads.

Although the Returning Void Cultivators move very fast, no matter how powerful their nuclear weapons are, they can't be beaten, but the sect's heavy ground can't move, and such a billion-ton nuclear warhead explodes, there is probably no protective array that can resist it, and one can level a major sect's dojo.

Even if you can't defeat those Returning Void Monks of the Ten Thousand Souls Sect, a high-yield super nuclear bomb flies out and destroys the Dojo of the Ten Thousand Souls Sect, but there is no problem.

Under the attack of that kind of super nuclear bomb, the only one who can escape is the Returning Void Monk.

If you return to the void, don't even think about escaping.

After joining so many refiners in the Thousand Machine Pavilion, the technological progress of the Armed Forces Department was faster than Zhong Yuan could have imagined.

In the past, there was a big gap between the level of weapons and the level of weapons on the earth, but now, it has surpassed the level on the earth.

If there is a confrontation between the two armies in Mochizuki Technopolis and the Earth Legion, Mochizuki Technopolis can use these weapons to completely abuse the Earth Legion.

Of course, it still made him feel that there was something inadequate.

However, after some refiners in the Thousand Machine Pavilion figured out some scientific concepts, they came up with a very bold idea, which made Zhong Yuan very interested.

They want to build a space battleship powered by nuclear energy, which has both the most advanced science and technology, as well as a very high-end Xiuzhen civilization, which can travel in the vast universe for a long time.

The space technology in the Xiuzhen civilization can ensure that when this space battleship shuttles through the universe, it is not very worried about the storage of materials, nor is it very worried about the energy problem.

In their vision, it would be a very large, long fusiform flying object, several miles long, but not very wide, like a submarine, narrower than the proportions of a submarine.

This flying object has a spirit stone drive system and a nuclear energy drive system, which will be able to carry tens of thousands of people to fly at one time, and the speed will reach an incredible height in a vacuum.

Zhong Yuan was interested in this, not because this space fortress could improve the strength of Mochizuki Technopolity, but because he felt that it made it feasible for people on Earth to carry out space migration.

There is no big technical problem, basically it is all existing technology, but it needs to complete a fusion.

Because there is no relevant data, some experiments need to be carried out, but the difficulty will not be very large, and the probability of success is relatively high.

After all, the best magic weapon of Qianji Pavilion is the flying magic boat, and the experience in this area is too sufficient.

Zhong Yuan asked those refiners to evaluate the cost, and it would probably take billions of spirit stones to build one.

Such a high cost is extremely rare in the cultivation world, but Zhong Yuan still agreed to such a decision without hesitation, and put forward his own requirements:

"It is better to be segmented, which can be disassembled or assembled, and it can also be equipped with some more weapon launch systems. ”

Only in the segmented form can he be put in a storage ring and brought back to the solar system and handed over to the people stationed in the lunar scientific research station in Huaxia, otherwise there would not be such a large storage ring to install such a large space battleship.

The earth is his real hometown, and if he has the conditions to make some contributions to his hometown, he is still very happy.

With so many people and so few resources, the more advanced science and technology there are, the greater the demand for resources.

As far as the resources on the earth are concerned, there are not enough years for human beings to build.

It would be better to help them with space migration.

Even if you can't immigrate, it's okay to find resources from space.

The solar system is too vast, and at the speed of a space battleship in the design, the possibility of crossing the solar system is very small, and no one has that lifespan.

However, in the nine planets, it is not impossible to cross that kind of possibility, but the time is a little longer, but it will not be longer than the lifespan of mortals.

If there is more progress in the future, it may be possible to travel between galaxies.

Such research must be done.

With Zhong Yuan's support, the Ministry of Armed Forces immediately set up such a project team, which received great financial support.

This project is the largest scientific research project of the Armed Forces Department of Mochizuki Science and Technology City, and the largest number of refiners and scientists are involved.

Because there's so much technology involved.

Including nuclear power systems, early warning systems, navigation systems, and weapons and equipment launch systems.

It can be said that it integrates all the cutting-edge technology of the surgical class, and it has hollowed out most of the scientific and technological strength and refiner team of the Armed Forces Department at once.

For their project, Zhong Yuan took out 30 billion spirit stones at one time, and said to the person in charge of this project team: "Don't worry about the problem of funds, you have to spend where you should spend, it doesn't matter if you are wrong, all you have accumulated is experience." If 30 billion is not enough, you can still ask me. ”

The person in charge of that project team was the elder of the Refining Hall of the Thousand Machines Pavilion, and building a super flying giant ship was his dream of entering the Refining Hall for the first time, but the funds involved were too huge, and it was impossible to realize it in the Thousand Machines Pavilion.

Unexpectedly, now that there is a chance to realize it, he was so excited that he burst into tears, and made a promise to Zhong Yuan: "City Lord, don't worry, with your support, I will definitely get it out!"
