A huge city unfolded in front of Chen Xin. Now the distance from the city is only about a kilometer, and at the foot is a square that seems to be paved with a whole piece of white jade, and the wall of the same white jade is about ten meters high, and together with the ground, it emits a faint light, making people feel the temple of the fairy palace. Chen Xin's angle could not see the extent of the city wall at a glance.

The most conspicuous thing is a towering golden tower in the middle of the city, which looks very mysterious in the hazy light.

There was no limit to the divine thoughts of the Black Forest, and Chen Xin carefully probed with the divine thoughts. Now Chen Xin's divine intensity, because of the opportunity and exercise, is much higher than the Hedan period, and Chen Xin's own estimation is at least equivalent to the Jindan consummation, and the distribution distance has reached about 10,000 meters. The powerful divine mind quickly explored the surroundings, and there were traces of formation on the ground and the city wall, and there was nothing abnormal, including that there was still no sign of life in the city.

Holding the principle of safety first, Chen Xin still walked cautiously, came to the edge of the city wall and jumped up, by the glimmer of the city wall and the giant tower, Chen Xin can still see the panorama of the city, the buildings of different sizes are neatly arranged, the most surprising thing is the wind shape and color of the building, each house is different, each has a strong personal style, or round, or square, a combination of various shapes, etc., each is full of individual beauty.

Chen Xin slowly approached the nearest house, a blue pyramid-like building. Walking to the door, Chen Xin habitually knocked on the door and asked, "Hello, is there anyone at home?"

Of course, no one will answer him. Chen Xin smiled, turned over his hand to push the door, because he felt that the door was made of metal when he knocked on the door just now, he subconsciously used the heavenly decision, and the door that had just been pushed half stopped, Damn! Not only this door, but the whole house is actually built of blue gold, no wonder this color is so gorgeous and natural! It's too extravagant! Anyway, this is also a third-level material! How much is it used to build a house! Chen Xin looked around again and said, "No, the buildings here are all made of refining materials, right? If it is really too extravagant." I'll check it out later, and explore the house in front of you to see if you can find information about the city.

Opening the door completely, and stepping in carefully and slowly without danger, Chen Xin breathed a sigh of relief. Looking up, he was startled! There was a person sitting on a chair not far in front of him, facing this with his left hand casually on the table beside him, and his right hand holding a cup on his chest, his handsome face with clear angles, looking at Chen Xin with a smile. Chen Xin was extremely nervous at this time, he had just used his divine thoughts outside the house to carefully probe the traces of life!

Thinking of this, he hurriedly said: "Senior, I'm sorry, I came to this city by accident, I thought that no one came into this house, I offended you! I hope you don't mind." ”

After speaking, Chen Xin waited for a while without waiting for an answer, and then said: "I really didn't mean to, I knocked on the door just now," there was still no movement on the other side, Chen Xin looked at the person who was sitting without even changing his posture, and boldly moved forward, or moved again without moving, or didn't move, is it a dummy?

Chen Xin simply walked to his side, touched it with his hands with an open-minded mentality, Chen Xin did not feel a trace of life characteristics under the physical contact, because the Heavenly Discernment had not yet been completed, a large list of material names suddenly appeared, I didn't expect this person to be a refining puppet!

This puppet is simply vivid just by looking at its appearance, and there is also a puppet refining method in the Heavenly Refining True Law, Chen Xin is also very curious about this kind of robot that can be said to be a true version of cultivation, so he studied this one carefully, and finally was dizzy by its complicated and cumbersome refining process, and secretly decided that he would never refine this thing. But today's puppet, in terms of appearance alone, is far more detailed than the puppet recorded in the Heavenly Refining True Law.

Chen Xin touched the puppet's face, and the skin refined from the juice secreted by the trapped immortal vine was still very elastic. It's just that why can't this puppet be moved? Where has the owner gone? Chen Xin was very curious about the puppet at this time, but it was important to investigate the details of the city first. I had to ignore the puppet for the first time and look around the room for clues.

It has been abandoned for an unknown number of years, and most of the objects have not stood the wear and tear of time, leaving only piles of ashes to prove that they existed, and only a few metal tables and chairs are still sturdy. Chen Xin didn't find any useful clues in this house. Only retreated and entered the next house, although he was prepared, he was still sitting on the same chair, facing the puppet at the door, and jumped slightly, Chen Xin walked several houses one after another, and still found nothing, but in every house there was a puppet facing the door, waiting alone and lonely, as if there was something to tell!

In fact, Chen Xin thought that if he could activate a puppet, he would definitely get a lot of answers, and he also found an energy slot under his arm in the hidden place on the puppet's body, and took out two spars that had exhausted his ability, but when he thought that the puppet was made of a large number of sixth- and seventh-level materials, it was the material used by masters above the distraction period to refine magic weapons, and the puppet grade ability made by them must be very high。

Now the only way to go is the golden tower, the tallest building in the city, and there should be a clue to it, right?

Walk through the strange buildings to a huge square with a golden tower in the middle. At this time, I also found that there was a building under the tower, which looked very much like the National Center for the Performing Arts in the previous life, but there was an extra tower in the middle, and Chen Xin walked to the building and quickly found the door. Chen Xin, who did not encounter any obstacles, entered the building safely.

The interior of the building resembles a huge movie theater, with rows and rows of seats. Facing a huge hedron screen, the chair has been reduced to metal shelves over the years. There should be no secrets in the unobstructed space, Chen Xin went straight to a small door next to the crystal screen, he felt that there must be everything he wanted to know.

Slowly pushed open the heavy small iron door, a wall attracted Chen Xin's attention, one by one small drawers covered the entire wall, each drawer was engraved with words, Chen Xin walked in and took a closer look at the text and the current Xiuzhen world The text is exactly the same, Chen Xin casually pulled open a drawer engraved with the word metal fusion 1, inside are small grids, there is a box in each grid, and there is also handwriting on the box Chen Xin picked up a carved ' The perfect fusion of Huang stone and aurora jade' box with the words 'carefully opened to reveal a crystal inside, Chen Xin gently picked up the memory crystal, and looked at the largest drawer in the middle that read 'Xinxing Era'. Chen Xin knew that he was looking for the key to unlocking the city's secrets.

Memory hedron is the equivalent of a computer hard drive. And it has the characteristics of almost never wearing, as long as a playback device can project the sound and image, the playback equipment Chen Xin does not have, but Chen Xin believes that it must be found here, the spar screen must be used to show memory spars. Chen Xin looked around and immediately found a machine, looking at its shape, the external structure should be the playing magic weapon, Chen Xin carefully studied and fiddled with it for a while, and then roughly understood the use of the machine, in a small hole opened by pressing it indiscriminately, took out a spar with no energy, and then put in an intact spar, and then went to the text 'Xinxing Era' took out all the memory crystals in the drawer, Chen Xin first put the last memory crystal in the order, pressed the play button in the groove of the playback instrument, and then quickly ran to the outside of the small room to see the big screen, now what he wants to know most is what happened to this planet, where did all the people go?

The screen that slowly lights up shows a moving picture. In the square I had just walked through, countless holes had been cracked, and spaceships rose up in it, and a pillar of light shot out from the top of the golden tower, and a hole appeared in the shell of the planet illuminated by the pillar of light, revealing a fiery red sky. The spaceships flew out one after another, flying towards the fiery red sky and disappearing into the sky.

A voice was heard from the amplification instruments around the hall. "Today is the first warrior to go out in the '1235th year of the Earth Yuan Calendar' to send back the news, they have almost occupied the galaxy closest to us, they are able to catch the soul fluctuations of life, the best isolation circle, no matter how weak the soul can escape their search. Once they enter our galaxy, our planet will not survive either. All the inhabitants have agreed to go on the expedition, even if all sacrifices may at least preserve our legacy. Being able to see this video shows that you are a cultivator just like us. If they enter, they will be greeted with an explosion that would destroy the planet. Okay, it's time for us to go. I really hope that someone can hear me say these words, which means that we cultivators are not extinct yet. At this point, the sound stopped abruptly and the screen went dark.

Chen Xin fell into deep thought, remembering that in a house that he had just explored, a calendar-like ritual vessel that was still in operation said 'Earth Yuan Calendar 2357'. That is, more than 10,000 years have passed, which basically coincides with the time of the Great Tribulation 10,000 years ago that was circulated in the cultivation realm. So far, no one has been able to say the reason for the Great Tribulation of the Xiuzhen Realm 10,000 years ago, and this image is also a secret and does not say clearly, what they are, what the taboo is, and even their titles cannot be clearly stated.

Since you can't figure it out, put it aside, this is Chen Xin's always rule of mind. Let's see if there's anything useful for you first.

The many memory crystals in the room are all good things, and judging from the buildings and puppets, the refining level here is significantly higher than that of the current cultivation realm. Compared with the Heavenly Refining True Method, it can also be said that each has its own strengths, and it is unbearable. The memory crystals are the cheats that are hard to buy. Looking at these memory crystals, Chen Xin couldn't help but think that if he learned all of these, coupled with the Heavenly Refining True Method, with the growth of his skill realm, he would definitely be able to stand at the highest point of refining in this world, and even in the future, he might be able to surpass the Duobao Dao people.

Then Chen Xin began to study ambitiously, but a memory spar about abyss iron made Chen Xin's patience drop to the bottom line, which has a detailed explanation of the refining of abyss iron, the fusion of various materials, and what utensils can be used to refine after fusion. It took Chen Xin half a month to fully remember. Thinking that there were still countless memory crystals waiting for him, Chen Xin did not have a certain confidence in completely mastering Xinxing's refining inheritance. This is not a huge project that a normal person like himself can complete. Let's do something that a lazy person like myself can do.

Next, Chen Xin picked out a set of defensive magic weapons, an attack magic weapon, a flying sword, and a puppet refining method marked as an all-powerful puppet among all the memory crystals, a total of four kinds of learning. Then, when the refining methods of these four magic weapons involve materials that you are not familiar with, you can find the memory spar of this material and learn it. In this way, until Chen Xin fully mastered these four refining methods, three full years had passed. In the past three years, I have summoned three Duobao Dao people, but there is no response.

In the past three years, once Chen Xin was bored, he watched the memory spar about the history of Xinxing as a movie, so he already had a deep understanding of the history of Xinxing. Since the beginning of the record, Xinxing has been a world full of cultivators. The population of the planet is not large, but the mineral resources of the planet are varied, and they are very rich, relying on the sale of resources. People all over the planet live a life of abundance. There is a lot of time to cultivate, but because there are not many cultivation techniques on the planet, and they are not very profound, there has never been a person who has ascended to immortal in Xinxing, and with the increase of cultivators, the years have grown. The people of Xinxing are becoming more and more perfect in their cultivation, and the realm they can cultivate is getting higher and higher. Xinxing finally appeared as a master of the Mahayana period, and the catastrophe was in sight.

However, this master of the Mahayana period discovered an extremely critical situation with a powerful divine thought. It turns out that due to excessive mining of minerals, there are countless huge cavities in the interior of the planet, which has greatly changed the weight of the planet and destroyed the gravitational force of the entire planet. Due to the very slow speed at the beginning, the people of the planet did nothing unusual except for some sensitive people who felt that the weather seemed to be getting hotter and hotter year by year, and now the speed of this pull is getting faster and faster, and it will become uninhabitable in about a thousand years, and finally turn into a big fireball, which will be slowly swallowed by the sun.

The masters of the Mahayana period informed the people of the whole planet of this amazing news, and most of the people on the planet did not believe the news, and then tried various methods to prove that it was a false news, but the result was to provide accurate evidence for this news...... Fortunately, the planet is used to trade with the outside world, and there are a lot of teleportation arrays built, and a thousand years is enough time for people on the entire planet to move away several times, so people's reluctance to their hometown is far more than the fear of the sun. But just as people were about to move out of work, a faint black spot suddenly appeared on the sun. People suddenly found that all the teleportation arrays on the planet had lost their coordinates, and no one was teleported over. This is to add insult to injury! No one can calm down. Because the location of Xinxing is very remote, and the galaxy in which it is located often has dangerous energy storms. The existing coordinates were recovered tens of thousands of years ago at great cost to the predecessors. Now it's time to send another spaceship to find a viable planet. Time is far from enough. Countless years of exploration have learned that the closest viable planet to Xinxing will also fly for three thousand years. After the panic calmed down, the people began to discuss and study countermeasures.

In the end, there are two options left, one is to build a large spaceship and fly all out of the planet to find life. Due to the limitations of production capacity, this method does not take all the people. Some must be sacrificed. The second is to find a way to resist the gravitational pull of the sun and stop Xinxing from flying towards the sun. This method is theoretically possible, but it is extremely difficult to implement. Not necessarily successful.

In the end, the two options were at odds, and the people split into two groups to implement their own actions. At first, some of the people who built the spaceship were full of confidence, but they encountered a problem that they couldn't get over at the beginning, the materials were insufficient, and the resources of Xinxing had begun to be depleted due to uncontrolled mining, but people didn't pay attention. And the over-mining has made Xinxing almost hollow out. This also makes Xinxing's own weight and gravity unbalanced. The reason for drifting to the sun. The materials left now can only build about 100 large spaceships, and even one percent of the humans on the planet can't take it with them. The majority of people still have a conscience, that is, a few people are only themselves, and they are not invincible to the power of the masses. Now there is only one way left for everyone, to resist the sun. It has to be said that there is a lot of strength in numbers, and the pressure of survival stimulates people's potential, and all kinds of ideas are quickly gathered together, and finally a final plan is made, with the sun facing the sun, there is a planet closest to Xinxing, which is a planet that the fastest spacecraft will fly for thousands of years to arrive, an extremely cold world. No spaceship dares to approach a terrifying place for hundreds of miles. It is the goal to increase the gravitational pull in order to reduce the speed of Xinxing's travel towards the sun, and it would be even more ideal if it could be pulled back.

The gravitational force is provided by the formation, which will be covered with gravity under the surface of the entire Xinxing, and the energy formation, when the back is facing the sun, the gravitational formation starts, and stops when facing the sun, and the energy of the gravitational formation is provided by the side facing the sun to absorb the sun's heat and convert it into aura, and people act quickly with the plan. There are materials to prepare. For those who transport materials, more people depict gravitational formations and energy formations on the top floor of the underground. During the construction process, it was found that there was a serious shortage of manpower. At this time, someone tried to use a puppet to help with the work, and found that the puppet was much faster than people in depicting repetitive formations. Immediately people began to create a large number of puppets. And the progress of the formation is getting faster and faster.

The ground is getting hotter and hotter, and people have migrated to live underground. And the arrangement of the formation has an additional thermal insulation formation. After nearly a thousand years of hard work by the people of Xinxing, the speed of Xinxing towards the sun finally slowed down and finally stopped. What disappointed people was that they were never pulled back. At this time, Xinxing's surface was already what Chen Xin saw. In this way, after another 10,000 years, the people of Xinxing have built the world below into a beautiful home, and the connection with the outside world has also been re-established. At this time, Xinxing is no longer a resource planet. Instead, it has become a production planet with many refining formation masters, especially the most outstanding puppet refining. Everything that Chen Xin sees now is what Xinxing has been built for I don't know how many years of development. It's just that the population is very small at this time. Most of the people, out of fear of past crises, moved out of Xinxing after the teleportation array was built. In the end, there are less than a million people left, and it is difficult to leave their homeland.
