After saying a few words, Zheng Xiyuan returned the room fee and left.

If you want to talk about Xue Ruolan's answer, do you still need to say it? That girl has to agree if she doesn't agree. It's very simple, because the Xue family has reached the verge of either life or death. If there is no one to help, it will be swallowed by the Nalan family sooner or later. Reality doesn't allow them to choose.

Sure enough, Xue Ruolan also followed Zheng Xiyuan back to Obsidian City in the magic array.

As for the caravan she brought, she had her butler with her, and he went back and forth from there. In fact, before she came, she knew it in her heart. Kelcott's pass was not so easy. Smuggling mecha to the Shenyin Empire is strictly forbidden by the empires of the mainland. Once discovered, without the Nalan family's hands, the Xue family will be finished. If it weren't for the forced end of the road. Xue Ruolan would never do such a thing.

Little did she know that her dear partner was planning to carry "this kind of thing" forward. But even if she knew, she didn't have a choice. It's so easy to get on Zheng Xiyuan's thief ship?

When he arrived in Obsidian City, Zheng Xiyuan handed over 200 million gold coins to Xue Ruolan. I believe that this money is enough to save the Xue family. He also handed over 100,000 gold coins and a list to An Xi, and asked him to buy them according to the materials on the list. And send ships to the three islands that they had previously requisitioned from Nangumo.

With that done, he flew towards the three islands that finally belonged to him.

In order not to arouse Nagumo's suspicions, he bought all three islands before. But since you bought it, of course, you can't let the gold coins go down the drain. Zheng Xiyuan wondered when to make use of these two islands.

Zheng Xiyuan didn't bother to think about the names of the three islands. The small island with the main spiritual vein is called Penglai Island. The one on the north side of Penglai Island is called Hojo Island. The one to the south is called Yingzhou Island. It is the three immortal islands in the story of Xianxia. There will be no Buddha-figures in this world. Zheng Xiyuan plagiarized it into a habit and used it unceremoniously.

Landed on Penglai Island. The Dark Moon turned into hundreds of long swords and flew out. Fly across the island. From time to time, large trees are cut down, and long arcs are carved on the ground of the island.

If you look at it from the sky of Penglai Island, a huge complex array is gradually forming on the island with the continuous crisscrossing of hundreds of flying swords. This array is divided into five circles, one large and four small. A circular array in the center, in the four directions of the southeast, northwest, and four small circles, are arranged. And Zheng Xiyuan was standing in the center of the big circle in the middle.

He took out five jade stones with a transparent color from his arms.

In this world, jade is not an expensive item, at least not compared to magic crystals. Just as a popular ornament among the common people. So I easily bought a bunch of them. These five pieces of jade. It is the best of them all. I don't know if there are spiritual stone veins in this world, and the spiritual power is so abundant, I think there is. Spirit stones are much better than jade stones for arranging formations. But now there is no hurry to refine something too advanced, just pay attention to it yourself in the future and find it.

Hold up five pieces of jade in the air. The three-flavored true fire slowly spewed towards the five pieces of jade. In the raging flames, the jade slowly melted into a milky white jade liquid, and some impurities in the jade turned into a black smoke and flew out.

Zheng Xiyuan pointed with one hand. The jade liquid is divided into five equal parts. Hand quickly changes mudras. The faster the movement, the sooner the movement, the more the hands turned into a mass of interlaced cyan fingers. Spell marks flew out of the shadows. It is engraved into five balls of jade liquid.

The five rays of blue, red, white, black, and yellow light rose from the five clusters of jade liquid. Five balls of jade liquefied into five balls. The blue, red, white, and black balls swirled rapidly around the yellow one.

"Formation, stand!"

The yellow jade in the center "popped" like a drop of water into the surface of the lake and submerged into the soil under Zheng Xiyuan's feet. The central main array of the five circles lit up with a golden light.

"The green dragon of the east is rising!" "The cyan jade liquid flew towards the east. The eastern side array lit up with a cyan glow. "Roaring !!" A cyan dragon emerged from the cyan circle and spiraled up, obscuring half of the eastern sky.

"The white tiger of the West stands proudly!" the white jade liquid flew towards the West. The western side array lit up with a white glow. "Whoop!!" A huge tiger phantom with white hair and black stripes was constructed out of thin air. Gradually become a substance. Lying on top of a mountain in the west.

"Southern Vermilion Bird Flying!" the red jade liquid flew south. The southern side array lit up with a red light. Magma slowly gushes out of the center. Soon, the entire sub-array turned into a sea of fire. "Yo !!" Firebirds flew out of the sea of fire, blended with each other, and soon turned into a huge Vermilion Bird. Fly above the sea of fire.

"Northern ......" Zheng Xiyuan's face suddenly turned pale, and sure enough, it was still a little reluctant to arrange this formation with the sword embryo realm. But he couldn't wait a few years for him to break through the Sword Infant realm. A mouthful of essence blood spat out, merging into the golden light on the ground. And he continued to shout:

"Northern Xuanwu Shen Abyss!" the black jade liquid flew to the north. The northern side array lit up with a purple glow. Purple lightning flashed. The sea in the north suddenly became rough. A drop of water rose into the sky. Fall into the formation. Suddenly there was a black glow in the water. "Woo!" Nine hideous dragon heads protrude from it. Xuanwu crawled, shaking the island with every step. Eventually it sank to the surface of the sea. The sea was calm.

"Formation into a !!" Zheng Xiyuan squirted another mouthful of blood. Condensed in the hands. He clasped his hands together, and the essence of blood condensed into a spell in his right hand. He was pinned to the ground.

The five golden rays of light that rose to the sky disappeared in an instant. Only the four divine beasts were left to guard the place.

"Boom. The place where Zheng Xiyuan was standing suddenly collapsed, and soon, a basin formed in the center of the main formation. In the surrounding void, a faint blue light surged rapidly towards the center of the formation.

Zheng Xiyuan jumped out of the center of the basin, and where he was standing, a trace of blue spiritual fluid was already pouring out. It turned out to be the crystallization of the purest spiritual power liquefaction.

This formation laid by Zheng Xiyuan is called the Quartet Divine Beast Gathering Spirit Array. It is a magic circle that uses the qi of the four directions to coordinate the power of the earth to condense the spiritual power of heaven and earth. It can also be said to be a combination of the Spirit Gathering Array and the Four Elephant Array. Use the power of the four divine beasts to accelerate the gathering of spiritual power in the spirit gathering array, and then use part of the ability of the spirit gathering array to maintain the four divine beasts in turn. And the extra spiritual power gathered into the spiritual fluid of the central basin. It is also the substance that Zheng Xiyuan intends to use as "fuel" in the future.

In addition, although the Divine Beasts of the Four Directions do not have their own thoughts, they will guard the magic circle on their own. Those who try to break into battle will be counterattacked. Although the materials used by Zheng Xiyuan are limited. The formation can only deal with an existence of the same level as him, but it is also a great thing in this world.

With a sigh of relief, he laid out this formation, which consumed a lot of natal essence blood. There is no year that cannot be made up. If he hadn't absorbed Antuoga's huge divine power, he would have almost fallen back to the Ning Dan realm. However, Zheng Xiyuan looked at the huge divine beast in the four directions. Make such a stylish thing. Tired to vomit so much blood, it's worth it!

I recovered my overdrawn spiritual power. Zheng Xiyuan looked sideways, but saw a ship quietly moored on Abbot Island in the north. But it was the ore sent by Anxi.

Ordered the ore to be removed. Fortunately, there are no four divine beasts to be seen outside Penglai Island. Otherwise, Zheng Xiyuan is afraid that there will be a lot of trouble.

Sending the boat away, Zheng Xiyuan ordered Dark Moon to turn into the form of a boat, carrying ore and flying back to Penglai Island. Begin to smelt the ore with three true fires.

In Genesis Z237. A very strong alloy was recorded. It was called "artificial heptogold" by Zheng Xiyuan. "Heptane gold" is a fairly high-grade refining material. It's also quite precious. In the spiritual world, it can be said that it is hard to find. However, once Zheng Xiyuan became interested in this kind of thing, he would completely understand the ingredients of this kind of thing and imitate it. However, he later discovered that heptogold is a metal nourished by the qi of heaven and earth, and it cannot be imitated artificially.

In desperation, similar elements can only be used for chemical simulation. The final "artificial heptogen" is very different from "heptojin" in terms of the conductivity of spiritual power. The hardness is also much worse, but it is not comparable to ordinary iron.

Zheng Xiyuan didn't plan to refine powerful magic weapons. It's just a matter of making some mass-produced mobile weapons. This kind of metal with low weight but terrible hardness has naturally become the first choice.

Zheng Xiyuan's practice is three days. Thirty tons of high-quality artificial heptane gold were finally refined. The first thing that was decided to be refined was the artificial heptyl gold refining facility. Otherwise, if you don't exhaust yourself to death in the long run?

When they arrived in front of the Southern Vermilion Bird Circle, the scorching temperature kept coming. Zheng Xiyuan slammed his fist on the ground, and a small pit was blasted out of the ground. Then the Dark Moon turned into countless shovels. Soon a diameter of more than ten meters. A large pit was formed six or seven meters deep. Zheng Xiyuan was also not polite, and directly sprayed the three-flavor real fire into the big pit. While sprinkling some special materials into the pit. It burned like this for more than an hour. Zheng Xiyuan stopped the three flavors of real fire. At the bottom of the crater, a crystalline spar was formed.

Zheng Xiyuan knows. These spars are refined by the three flavors of true fire, which is quite heat-resistant, and will not be burned even if it is exposed to fire. Pour the remaining material into a large pit. Suzaku flying in the sky let out a long howl. A crimson flame erupted into the pit. The material soon began to melt, and the excess impurities in it were constantly burned out.

The new artificial heptane gold was quickly refined.

Although it is not as good as the ones that Zheng Xiyuan refined with the three-flavor true fire, it is also very hard.

Under the control of Zheng Xiyuan. These uncondensed heptane gold quickly turned into parts in the air. Piece it together.

Three days later, Zheng Xiyuan breathed a sigh of relief. looked at the three assembly lines in front of him with satisfaction. and fifty industrial robots.

These three assembly lines are the production machine robot, and the flying shadow system, and the spiritual kinetic energy assembly line.

The assembly line of industrial robots is relatively simple. It is unlikely that artificial intelligence will be produced in this case. This kind of intelligent system made by Zheng Xiyuan is quite low-level. Constructed robots will only take instructions from Z237 to act. I can't think about things. Problems can occur when they are affected by external forces. However, Zheng Xiyuan just wants some robots to control the monotonous assembly line. This kind of thing is not difficult for him, and there are design drawings in the genesis Z237 as a detailed reference. This assembly line was "refined" out of thin air by Zheng Xiyuan in just three hours.

The Flying Shadow system is an auxiliary system for the driver of a mobile weapon, which can be connected to the driver's neural network to control the mobile weapon. It was something designed in the early days of Chu Tianxie in the previous life, but it was never put into production once. It wasn't of much value to him at the time. But now that I think about it, this thing is just right for him who doesn't have the conditions to mass-produce artificial intelligence.

The last type of psychic kinetic device is, to put it simply, something similar to an engine. It's just that this is powered by spiritual power. Where there is spiritual power to absorb, it can operate infinitely. You can also store spiritual power in normal times.

For this world, these three things are very rebellious. However, for Zheng Xiyuan, it is still far behind.

It's been seven days since I arrived on the island. The first batch of ore purchased from Xue Ruolan has finally arrived. To say the least, there were ten times more materials than when I came back last time. Stuffed with twenty cargo ships, about 10,000 tons. After unloading on Abbot Island, crash into a half-human-high wooden crate. It was piled up into ten hills about 20 meters high. Zheng Xiyuan gave Xue Ruolan 200 million gold coins, which was almost 10 million tons according to the average price of 20 gold coins per ton of ore. Carrying these ores will undoubtedly be a heavy physical task later on.

Zheng Xiyuan has never been in the habit of being a coolie. For him, once and for all, it's king. Fly towards the Blue Dragon Circle.

The Green Dragon Circle was in a dense forest, and the huge Green Dragon was entrenched above the trees. Quite majestic.

Green dragon wood. Under the aura he exuded, the island was already lush and the woods were even more lush.

Zheng Xiyuan pinched out a trick in his hand. Once again, he forced out a mouthful of essence blood, divided it into thousands of parts, and integrated it into every tree species in this forest. Thousands of trees here swayed and turned into large and small tree people in an instant.

Nodding with satisfaction, Zheng Xiyuan was not willing to let humans set foot on Penglai Island. But the factory of the future cannot be without workers. The largest of these treants can be used as guardians of the island, while the smaller ones can be used as coolies. The island is full of spiritual power. plus a drop of Zheng Xiyuan's essence blood. These treants can survive forever.

Following Zheng Xiyuan's order, the tree people lined up in a long line and walked towards Abbot Island in the north one by one. The basalt in the water floats up and forms a hill. Tree people ride on this hill. It's on Abbot Island. Boxes of materials were picked up from Abbot Island. and returned to Penglai Island on Xuanwu's back.

Each of these tree figures is five or six meters tall, and the two of them are so thick when they hug each other. Handling about three tons of ore at a time is basically not a problem. About 3,000 tree people, two or three trips back and forth, have all finished moving ore.

Boxes of ore were poured into a large pit and smelted by Suzaku.

In the end, the large piece of artificial heptane gold that was smelted was grabbed by the sharp claws of the white tiger, and a uniform piece of iron was separated, together with another batch of insulating materials. He was carried to the production line by the tree man. Under the operation of 50 industrial robots, the production line also began to work in full swing.

In the afternoon, the first batch of 300 robots manufactured by the production line was manufactured.

Zheng Xiyuan was relieved that his small factory was finally on the right track.

Because Xuanwu has the ability to control celestial phenomena. Zheng Xiyuan is not afraid that these devices will be exposed to the rain. The plant can not be in a hurry. I took an interesting look at these working robots. Finally, Edgeworth left Penglai Island.
