Zhang Fan was not in a hurry to leave the Central Holy City, because there was always a premonition in his heart: his preparations did not seem to be very sufficient, and it was better to have more means. After all: the strength of the overall cultivation world of the legendary Boundless Continent's Profound Generation is one level stronger than that of the western border of the Boundless Continent, so the "Protagonist-level Transformation God Genius" converted according to the western standard in his previous estimate may not be able to have a relatively safe position in other places. Therefore, in the Qiankun Shield, he still took a huge risk and spent a certain amount of time to endure more than 30 consecutive "Z-ray refining" to increase the appearance protection to the original level of about 16,000 times, which is equivalent to just converting his original strength to reach the level of refining the three grades of the void, and the overall strength has risen by seven grades, almost consuming most of the advanced scientific and technological material resources related to it in the civilized society that has been cultivated over the years.

Subsequently, Zhang Fan used these scientific research resources and even energy resources of civilized society to produce at least thousands of energy storage talismans in the following thirty years, consuming the previous hunting gains, and further improving the warhead magic circle of the Shenlei cannon shells, and even accommodating more complex energy storage talismans to further enhance combat effectiveness. It wasn't until Zhang Fan felt that according to the theoretical calculation, not counting the mental power factor, the combat power fully deployed by his various means could match the conversion of the combined nine grades, that he was a little low in his heart. Of course: because Zhang Fan is not very familiar with the level of refining and the level after it, these are just theoretical "equivalents". If you really encounter a strong enemy in the merger realm, and you haven't been seconded yet. Of course, his choice is to avoid war if he can.

In the forty years or so that Zhang Fan further used the core civilization methods of the Xuanfa School to cultivate and upgrade, the industrial civilization of the entire Xuanfa School in the neighboring areas also expanded by about 1,000 times according to the five-year plan of the Stalin era or the extreme speed of the peak of the Four Little Dragons, which doubled every four years, with an average annual economic growth rate of 18 to 19 percent. A major breakthrough has also been made in technology. When Zhang Fan came to the area adjacent to the Central Holy City of the Xuanfa Sect again, almost all the areas within a radius of one billion square kilometers had become an area full of spectacular buildings, and the air traffic was vertical and horizontal, which was quite like the future science fiction style of the past. By constantly digesting other new migrants, the population size has also reached about 50 trillion.

According to the direction roughly given by Zhang Fan, the armament system of the entire central region has also taken on a new look, and there are no longer too many shadows of the military system of the early 21 st century. Through the efforts of less than half a generation, a total of about 2,000 "space warships" have been built

Of course, after several tests and the loss of dozens of specially built "space warships," it has been proved that it seems to have a very powerful "soft barrier" at an altitude of about 50 kilometers above the earth's surface, and it is useless to use a variety of means of attack and breakthrough means.

Zhang Fan is not a big science and technology master, more than the technology of the 80s of the 21st century, he can't provide too much technical guidance, not to mention that this is not the earth, and many things can't be copied and copied. Therefore, he politely asked the trusted "Commander of the Combined Fleet" through the Thousands of Miles of Mind Transmission Technique: "How is it? In the past 40 years, according to my general prompts, the performance and combat effectiveness have been improved, right?

"The scale is a bit unsatisfactory, but at the cost of a slower rate of expansion, it should be able to reach 10,000 standard warships within ten years. Each warship is about five kilometers long and about six hundred meters wide, and under normal circumstances, only the main pilot and two co-pilots are maintained in shifts, and other systems can be handled by artificial intelligence. In order to install a nuclear explosion pulse-ray device, the frontal protection is somewhat unsatisfactory, only reaching a thickness of about six meters, which is converted into the hard protection level of 550 meters of homogeneous steel armor or the thermal protection level of standard steel armor of about 220 meters. When a pulsed ray attack fires, a single attack can fire a X-ray radiation attack that is close to the peak of the Avatar Monk, which is about 10 million tons of equivalent X-ray radiation attack. Of course, even at high altitudes, the speed of the spacecraft has a lot of resistance, and at the highest altitude that can be reached, the short-term speed can only reach 100 times the speed of sound, and the overload can reach 15 times the gravity... ”

"How about the detection ability of the spiritual radar," Zhang Fan asked.

"The long-term alert mode has an average kilometer of tens of millions of kilowatts, and the combat mode can reach 100 million kilowatts, coupled with the expansion of the radar diameter to hundreds of times, the signal processing capability has also increased to about 1,000 times in the past few decades, and the detection distance of air targets in the cross-sectional area of the square centimeter-level radar has increased to about 10 million kilometers, and the reconnaissance capability of the square centimeter-level targets can reach 66 million kilometers when the entire fleet carries out coordinated reconnaissance, and the search and attack capabilities for illusion targets have also been enhanced after using some spirit stones。。。 ”

Zhang Fan lowered his head and was silent, because even if he understood this, he still couldn't accurately deduce the approximate strength of the fleet he had created. In Zhang Fan's view: Although the attack and defense power are quite passable, the target is too obvious, and the stealth efficiency is too poor. Placing a few symbols is also very limited for such a large and signal signature target. And: the dynamics are too bad. And although the radar signal processing ability is roughly calculated to be about 100,000 times stronger than the 21st century in my impression, which is equivalent to 17 overturned Moore's laws, it is still somewhat unsatisfactory. This radar system model seems to be a bit outdated.

"In this way, let the fleet gather and prepare for battle, and practice at a certain distance from the core area now, and I will see how much your combat effectiveness has improved over the past few decades... Zhang Fan said with some unease. Zhang Fan, who planned to leave the area around the Central Holy City, was actually still a little worried about the defense capability here. If he couldn't deal with one or more ordinary god powerhouses, Zhang Fan still planned to let this civilization develop and grow a little bit. In that way, I have some confidence to travel far away.

It's not entirely that there is too much responsibility for these mundane realms that they have created. Zhang Fan found that with the development of the mortal world under the maintenance of a certain level of modernization and healthy order, the strength of the Supreme Flame of Perfection seemed to have become stronger in the perception of spiritual power. It seems to provide at least a big realm, which is obviously a big hole card to solve strong enemies by yourself. If something goes wrong in this mundane civilized world, maybe your own Flame of Perfection will also be unlucky...

In this way, after more than ten days, in a place not too far from the core area of the Central Holy City, which was more than 20 million kilometers away, the air fleet with a total tonnage of 2,000 ships and a total tonnage of 100 billion tons opened a formation with Zhang Fan himself at a distance of about 10,000 miles.

Under Zhang Fan's order, although the joint command was hesitant, fearing that it would accidentally injure the divine master or bring about something too big, it still did not dare to resist Zhang Fan's final order. More than 2,000 warships linked together launched an attack in the direction of a void thousands of miles away with their main guns almost at the same time. Zhang Fan did not use illusion or stealth techniques to resist.

The high-frequency laser is almost invisible from the side, but the penetrating power and huge energy instantly turn many gases and particles in the air into ions and explode outward, like a straight and tangible yellow lightning bolt converging into the distance.

The violent shock wave covered the range where Zhang Fan was, making Zhang Fan, who had increased his protection tens of thousands of times higher than before, feel a little uncomfortable. Zhang Fan can be sure: If it is an ordinary god-level powerhouse, he will definitely be wiped out in the face of such a joint attack. Even if you face a hit attack from a spaceship, you will inevitably be hit hard. Of course, at this time, I am obviously a special case.

However: can this attack power really represent real combat capabilities?

"Lord God ... Is the Lord alright?" the pulsating radio waves seemed to be a tentative inquiry.

"It's okay, you can attack with confidence. Before, it was just a test or two to avoid danger. Now it's time to get into the real fight!"

Hearing the news that Zhang Fan was still safe and sound in the face of the fleet's joint fire attack, many people's hearts were relaxed, and they no longer had the pressure they had before. Once again, heavy combined fire was ready. Unlike many low-powered laser devices, directed energy devices that are equivalent to the entire energy of a 10-million-ton nuclear bomb still require at least a second or so of attack cooldown.

However, at this moment, on the light curtain and radar curtain of the battleship group, Zhang Fan, who was thousands of miles away, suddenly conjured up multiple gods, as if hundreds of signals were reflected from different directions. The only good thing is that these signals are not too far away from each other.

Under the circumstance that the level of automatic control has reached a considerable height, almost the entire combat process is automatically controlled, and when the next second of firing, the fleet's automatic control system begins to bombard at a long distance in a focused manner in accordance with the priority order of the threat judged after signal processing.

However, none of the more than 60 bombardments that lasted for a minute hit Zhang Fan himself, but only made Zhang Fan feel some heat waves brought by high-frequency rays sweeping through his surrounding area. This made Zhang Fan shake his head helplessly.

Zhang Fan's figure shook suddenly, and in less than ten seconds, he approached from a distance of 10,000 miles to a distance of only about 1,000 kilometers from the ship group, and the illusion attack did not seem to be of much use to the ship group of automatic intelligent combat, which made Zhang Fan feel a little relieved. However, under the long-range bombardment of the next thunder, the seemingly powerful ship group could no longer withstand the blow, and in a short period of time, more than 200 warships seemed to lose control under the fierce lightning strike.

Recalling the entire battle process, Zhang Fan was still a little disappointed: "The attack, attack speed, and hard protection are all okay." The ability to confront in terms of mobility, mental power, electronic warfare, etc., is too poor, and the defense is too poor for means of attack other than physical and thermal. I have a general feeling: The entire fleet should not have the level of a relatively mediocre Yuanying peak master in front of people who really know a thing or two about you. Even if you don't know much about you, as long as you are not too arrogant or unlucky, you will definitely not be able to cope with the powerhouses of the God Transformation Realm. Over the years, you've relied a little too much on technology outside of the occult arts. Ignoring the combination of talismans, formations, spiritual means and scientific and technological means to make up for their own shortcomings. It seems that it is not time for me to leave ... ”

In this way, in the next few years, Zhang Fan left a lot of spirit stone materials and even assisted the fleet to improve its recognition, stealth power, and ability to resist multiple attacks, so that the combat effectiveness of the entire fleet could be improved to the point where it could threaten the pinnacle-level Yuanying master even if they understood each other.

Of course, at this time, those high-ranking cultivators of the Xuanfa Sect who had been practicing in retreat on the Tower Mountain of the Central Holy City according to Zhang Fan's request had finally decided not to be silent anymore. According to the agreement a hundred years ago: in the development stage, high-ranking monks of the Jindan or Yuanying level should not show up as much as possible. However, when the strength of the mortal realm seemed to have developed somewhat beyond many people's expectations, and even developed towards the level of god-transforming combat power, many high-level cultivators still couldn't sit still.

As a representative, an old man at the peak level of Yuanying took the initiative to admonish Zhang Fan through a unique way of contact: "Is it really safe for the Divine Lord to increase the power of the mortal world to such a point? ”

Of course, Zhang Fan knew that for these people who were not inferior in intelligence and had rich experience, general explanations were useless. Therefore, he didn't mind lying and said, "I've heard some of you talk behind your back, saying that the mortal realm has a strength comparable to the peak level of the Yuan Infant is going against the way of heaven. If this is the case, do you think that the heavens will not punish you for this? I'm afraid that many of you should also know that there should be a master or even a master plane that is more powerful than the gods, right? So far, these things have not been interfered with, and it has been proved that they are the Composite Heavenly Dao. You can rest assured: I have specially checked the procedures of the ruler of the mortal world and even the relevant social system, and there will be no big problems... ”

Zhang Fan thought about it, but he still didn't fully confess that his purpose was to ensure and enhance the power of the Supreme Flame of Perfection, after all, no one could guarantee what kind of trouble this secret leaked might bring to the civilized area near the Central Holy City. At the same time, after a period of observation, Zhang Fan also roughly believes that the higher the technological level of the society, the more advanced it will be on the whole, although there is a certain risk, but a world of semi-mystical and semi-technological civilization, in general, is still much stronger than the cultivation world of the underworld cultivating immortals, and it is not unacceptable to himself.
