Li Yuxuan and Filson took the guards in the vast sea area, searching and collecting all kinds of mineral deposits, but they searched the entire sea area and found no oil and natural gas, and no oil and gas were found on the land in the werewolf clan, bear clan and tiger clan area, seeing that the Dongyuan Star is not short of plants that have grown for more than 10,000 years, but there are no plant fossils, is it possible that this Dongyuan Star has never had a crustal change? Li Yuxuan was puzzled, and then recalled that Dongyuan Star had lava pools and mountains, but no volcanoes! Could it be that these mountains are also man-made? If this assumption is true, and with the base of the large attack machinery that has been excavated, it is likely that this Dongyuan Star is an abandoned super-giant space battle fortress.

When Li Yuxuan and Filson searched for a trench five hundred kilometers deep from the water level, they unexpectedly scanned a huge alloy metal outline hidden in the reef at the bottom of the sea with their divine sense, and the reef was already covered with a thick layer of fine sand, and it was covered with a variety of rare undersea plants, such as the Knife Light Spirit Grass used for the defense of the Fish-Man Clan, there are dozens of plants here, most of which even Filson has seen for the first time, but the plants he can recognize are all precious species, or have important medicinal value, or are the same as the Sword Light Spirit Grassto build a defensive position.

Li Yuxuan scanned the hidden entrance hidden in the fine sand with his divine sense, didn't say anything, covered the shock in his heart with a calm expression, and led everyone back to the location of the Fish-Man Palace, and Filson commanded people to empty the items in the palace, Li Yuxuan waved his palm to crush the coral that built the palace into fine particles and sprinkled it around, and batches of corrosion-resistant molten metal mixed with rock molten slurry swayed out in Li Yuxuan's hands, and at the same time, the outer contour of the condensed and magnificent dragon-shaped ten-story building was formed, A series of pure mechanical dragon guns, underwater torpedo launchers, and underwater sonar thermal radars were set up at the observation ports on the periphery of the building, and the Broken Dragon Stone, a mechanism usually used in cemeteries, was arranged at the location of the city gate, and the hundreds of tons of heavy city gates and the surrounding city walls could withstand the skill bombardment of any True God Realm cultivator.

Li Yuxuan carved a reinforced formation pattern on the periphery of the city wall that had not yet solidified, and used electric energy to drive the formation to work, arranged lighting facilities and lines in the city, arranged five tidal generators to generate electricity with the help of the surging water energy in the center, built a row of cultivation rooms above the water energy source, and built a food processing base in the city, a production plant for consumables such as torpedoes and dragon guns, and beautifully decorated the residential and production areas in the city.

Li Yuxuan invited Filson and his entourage to enter the newly built new Fish-Man Palace that can accommodate 500,000 fish-people to live, and explained the use of various basic living facilities and defense facilities, and the fish-people who accompanied Filson into the new palace were stunned, never thought that one day they could live in such a place, Filson was embarrassed to watch his generals immersed in the new palace building, so he had to personally record the various points explained by Li Yuxuan, so as to avoid the invasion of foreign enemies at that time, dragon guns and torpedoes will not be used, even if it is daily residence, Those lighting facilities and living facilities also need to be used by the people.

After Li Yuxuan finished explaining the new residential area of the Fish-Man Clan, he pointed to the small island ten nautical miles to the east and said to Filson: "Patriarch Filson, on this small island, I will build the above-ground part of the Fish-Man City, mainly entertainment area, industrial area and commercial area, with a small number of residential areas, and the defense system of the above-ground Fish-Man City and the underwater defense system are integrated, which can be used together when encountering an attack. In normal times, trade between cities is carried out by the Fish-Man City on the island, and keeping the underwater Fish-Man City secret can also leave a way out in a crisis. ”

Filson nodded gratefully, and said: "The fish-man clan listened to the arrangement of the Holy Demon King, and knew that the Holy Demon King could build such a beautiful, dreamy home, what kind of confusion did I make, and I also sent people to block the holy demon army, I really regret not being in the first place, otherwise with the fish-man army led by Fisher, to deal with the attacking saint clan and demon clan, and keep them back, those warriors of the Praetorian Guard would not have died in vain." I will send someone to follow the king to record the rules of the use of the Fish-Man City on the island, and I will first teach these bastards how to use the facilities of the underwater Fish-Man City, so as not to be ruined by the bastard boys for such a good facility. ”

Filson smiled bitterly, beckoned his three sons, who were more clever, to follow Li Yuxuan to the island, and repeatedly told him to be sure to record the use of various facilities.

Li Yuxuan flew over the island with the fish-man clan, first leveled the island with a golden spiritual power, and dug out some foundation pits, and then poured a torrent of steel into the surface of the island, and quickly and accurately formed under the control of Li Yuxuan's divine sense, without the slightest error and trachoma, just in the blink of an eye, the red steel outline was formed, on the surface of the steel outline with a high temperature of thousands of degrees, Li Yuxuan's illusion and consolidation pattern were also used as an energy source.

Li Yuxuan has the construction experience of the previous four cities, in the construction of the Fish-Man City on this small island, the flow of water, the torrent of metal and magma mixed dreamily created the basic structure of rows of various buildings, flashed into these buildings, output synthetic special metals to create the precision parts in it, and assembled at a speed approximate to the speed of light, but in three hours, the construction of various facilities in the Fish-Man City on the island was completed.

Li Yuxuan personally debugged each facility, absorbed the problems of the facilities that failed in the first four cities, optimized and fine-tuned, so that each facility was in the best operating state, approaching the state of zero wear and constant power, and beckoned the sons of the three fish-man patriarchs Filson, to introduce in detail the operation essentials of each facility, the operation requirements, the pricing of various commodities, the pricing of labor payment and other basic elements of the unified economic system of the five major cities to which the holy demon belongs.

Filson's three sons nodded incessantly, quickly recording every sentence Li Yuxuan's narration, for fear of missing half a word, and looked at Li Yuxuan with a look of reverence, it was hard to imagine that this Holy Demon King, the first combat power of Dongyuan Star, also created a precedent for Dongyuan Star in the mechanical and economic fields, so that the people to whom the Holy Demon belonged could live a life beyond imagination, which can be called the miracle of Dongyuan Star.

As a large number of Fish-Man people and mortal-level warriors arrived at the fish-man city on the island and the fish-people at the bottom of the sea, under the command of Filson's father and son, the official operation began, and the people of the fish-people and mortal-level warriors were jumping with joy and celebrating a happy new life.

Fisher led the soldiers of the Fishman Legion to be refining blood, refining bones, refining souls, and the terrible screams echoed in the sea area, from time to time there were Fishman soldiers who couldn't help but feel pain and fell into a coma, Miao Miao took the soldiers of the True God Realm to carry out emergency rescue, with the strength of the True God Realm, only barely kept nearly 20,000 Fishman Legion soldiers did not blow up, all of them passed the three refinements without danger, after the pain, they experienced the reborn strength soaring, and all the Fishman Legion soldiers felt that this pain was worth! With the military literacy training, combat formation drills, and cultivation exercises, the soldiers of the Fishman Legion have seen an infinitely bright future, and know why the Holy Demon Legion is so powerful, technically it is not at the same level at all, through the purification of the power of the three refining bloodlines, some of the elites of the Fishmen Clan have even appeared atavistic phenomena, some are closer to the direction of the dragon, some are closer to the direction of Kunpeng, and some are closer to the direction of the dragon whale, all of which are to activate the trace of ancestral blood in the bloodline, so that you can obtain low-level bloodline skills.

Miao Miao smiled and reminded Fei She: "This blood refining, bone refining, and soul refining can only play a role when it is run for the first time, and the effect of artificially carrying out three refining in the future is very small, but the danger of the explosion falling is very great, and it can only challenge the difficult tribulation in the tribulation, although it is dangerous, the benefits are also great, our lifeforms of Dongyuan Star are all very thin ancestral blood, and it is extremely difficult to completely atavistic to the ancestors, according to the calculation of the Holy Demon King, at least to the small universe realm, it is possible to completely atavistic and inherit all the bloodline skills of the ancestral blood, In order to make up for the weakness of the transitional stage, by cultivating the cultivation techniques provided by the Holy Demon King, the speed of increasing strength would not be slower than that of the ancestor race. ”

Fei Sher's own vague realization had confirmed what Miao Miao said, and immediately thanked Miao Miao for reminding him, and sternly instructed his subordinates not to practice again without permission, it would be dead! (To be continued.) )
