(Happy National Day!)

In order to increase the probability of success, Shui Sheng simply added all the remaining two spiritual materials for refining space treasures in his hand to the Fu Demon Tower, and intercepted a part of the Tiangang Stone from the black stick and added it to the tower, so that this new Fu Mo Tower, the tower body is more than twice as tough as before, and the internal space is even more considerable than originally envisaged.

With the addition of a large number of earth attribute treasure Nine Heavenly Resting Soil, according to aquatic estimates, the internal space at the bottom of the Fu Demon Tower can reach more than 100,000 li wide, and even the space on the top floor is thousands of miles long and wide.

The reason why the space immortal treasure is more precious than the offensive and defensive immortal treasures of the same level is that it can continue to expand and evolve, step by step to upgrade and evolve, for example, the aquatic life can now directly move some spiritual ore spiritual veins with rich spiritual energy into a certain layer in the Fu Demon Tower, so that the monks who are ingested into the tower can use the rich spiritual energy in this spiritual vein to cultivate.

You can also directly move the source of earth fire in the Black Flame Valley to a certain layer of the tower, so that this layer becomes a prison cage of hell, and at the same time, you can also add various prohibitions to the tower, and you can use these prohibitions to trap the opponent when fighting the enemy.

Of course, whether it is the spiritual veins of the Spirit Mountain that are moved into the tower, or the Hell Prohibition has a limit, and if it exceeds the carrying capacity of the Fumo Tower itself, it will cause it to collapse.

In order to verify the power of this tower, Shui Sheng, Tian Peng, and Liu Donghai spent several months setting up many prohibitions and various defensive measures in the fourth layer of the Demon Tower, and moved several sources of earth fire in the Black Flame Valley into the fourth layer of the pagoda.

This purpose-built space of Hell is under the blessing of prohibition. The temperature was even hotter than several of the strongest places in the Black Flame Valley.

I have tried the power of the Demon Tower, and witnessed the successful refining of two immortal treasures. Tianpeng and Liu Donghai couldn't help but feel itchy, and they also wanted to upgrade the treasures in their hands. And Shui Sheng also wanted to accumulate more experience in refining immortal treasures, and the three of them hit it off.

In order to avoid defeat as much as possible, the next target fell on the seven purple-gold flying swords that Tian Peng had obtained from Fan Yao Immortal Monarch.

Refining flying swords is the best at aquatic life, and for Tianpeng, the seven Saint-level Lingbao-level flying swords are not as good as a fairy sword, and the materials used in these seven flying swords are also extraordinary, and they can even be strangled by the Tiangang Sword Array without damage.

In order to increase the power of the immortal sword, Tianpeng deliberately added some extremely precious thunder attribute spiritual materials given by Doumu Yuanjun in the past to the sword embryo.

The second fairy sword came out half a year later, and the sword name was Zixiao!

Although the power of the law contained in Zixiao is slightly inferior to that of the Seven Stars. Tianpeng was still ecstatic, and his next target was the natal magic weapon that had followed him for countless years, the silver axe.

Unexpectedly, this refining ended in failure, and even the silver axe was not destroyed.

In addition to being disappointed, Tian Peng took out a shield of the top level of the Holy Rank Spirit Treasure and added a lot of rare spiritual materials to transform it, but as a result, it failed again.

Thinking of the previous eight consecutive failures. Tianpeng suddenly stopped the idea of transforming and upgrading the yin and yang double rings.

Immediately afterwards, Liu Donghai's spear magic weapon and a seal were destroyed at the last moment of formation.

Four failures in a row left the three of them deep in thought.

Thinking about it carefully, the main materials used in the three treasures of the Seven Star Sword, the Demon Tower, and the Zixiao Sword all came from the Immortal Realm, and even in the Immortal Realm, they were rare and difficult to find. And the silver axe and shield of the canopy, and Liu Donghai's spear and seal, although they also added a lot of rare spiritual materials in the heavenly realm. But there are no Tiangang Stone, Taiyi Essence Gold, which only exist in the Immortal Realm and even in the Sanqing Saint realm.

Could it be that only these rare spiritual materials from the fairy world have been added. In order to successfully refine the immortal treasure?

After some deliberation, the three of them put their next target on the black long knife that Liu Donghai had obtained from the Thousand Eyes Demon Clan. The sharpness of this long knife was not inferior to the Tiangang Sword in the hands of Shui Sheng, and the space where the Thousand Eyes Demon Clan was located was also an independent space higher than the Heavenly Realm.

In order to increase the probability of success, Shui Sheng provided some Tiangang stones to integrate into the knife embryo, and the three of them adjusted the Great Array of Spiritual Attraction to increase the power of the Great Array, so that the Great Array could absorb more Heaven and Earth Spiritual Qi.

Sure enough, this long knife was successfully cast, and it was named Tiangang Demon Killing Blade by Liu Donghai.

The four immortal treasures were all transformed on the original basis, and none of them were directly refined from spiritual materials, and the three of them couldn't help but feel regretful.

It's a pity that the rare spiritual materials in the hands of the three of them that may have come from the fairy world have been exhausted, and it is impossible for the aquatic beings to constantly intercept the Tiangang Stone from that black rod in order to transform other magic weapons.

This black rod made from the melting of the entire Tiangang Mountain has a higher status in the aquatic heart than the Seven Star Sword, the Burning Sky Mirror and other treasures, and not all the treasures are suitable for adding Tiangang Stone.

After some careful consideration, Shui Sheng decided to refine an immortal treasure-level flying boat.

The Heavenly Wind Warship was seriously damaged by meteorite rain outside the Nine Heavens back then, and it was repaired many times but could not reach its original state, while several other Saint-level Spirit Treasure Rank Demon Boats were also difficult to enter the Aquatic Eye.

As for the boat to heaven, although it is fast, it is limited by its small size, only three small quiet rooms, and it is okay to travel occasionally on behalf of others, and it is not suitable for long-distance travel in a particularly harsh environment.

The flying magic weapon in the shape of a meteorite mountain obtained from the leader of the blue-eyed golden mastiff back then was fully stimulated, and after it was fully stimulated, it was more than ten miles long and short, more than ten times larger than the area of Tiangang Mountain, and there were beehive-like caves all over it.

Even with such a large volume, the flight speed of this magic weapon is still not much slower than that of the Tianfeng Warship, and this magic weapon can withstand the bombardment of meteorite rain from nine days away, which is far tougher than the Tianfeng Warship.

Aquatic beings have carefully inspected it countless times, this magic weapon does not look like a pure acquired refining, but rather like a transformation and sacrifice of a naturally generated mountain, perhaps the material is too hard, and the beehive-like caves are also built according to the situation, not directly excavated.

With Allure's knowledge, I didn't recognize what material this treasure was made of back then, because the area of this treasure after stimulation was too large, and it was too ostentatious to control, whether it was in that secret realm or after returning to the cold underworld, Shui Sheng never took out this treasure to use.

This "mountain" is undoubtedly the best thing for refining the flying boat, and for the aquatic beings with the seven-star sword, it is not too difficult to break through this mountain.

Next, the three of them were in full swing into the trial of the flying boat, and this mountain-shaped treasure was also split into five parts by the water.

Even though the three of them had a careful plan and a tacit understanding, and the material of this mountain-shaped treasure was excellent, it was only after three successive failures that it was successfully refined in the fourth trial.

This flying boat, which is named "shadowless" by the aquatic life, is bright white all over, like a shuttle, and has a length of 100 zhang after it is opened and excited.

Aquatic added a large number of wind attribute spiritual materials to the boat, and after refining the boat body, it laid a lot of prohibitions in the flying boat, and when the prohibition was fully opened, the speed of this boat was several times faster than that of the Tianfeng War Boat, whether it was aquatic, Liu Donghai, the Fire Beast, or the Earth Wing Demon under the canopy seat, it was difficult to catch up with all the supernatural powers, and when flying from the sky, I am afraid that even the monks of the Earth Immortal Realm could not see the existence of the flying boat with the naked eye.

The sturdiness of the body of this boat is also remarkable, under the full ban, except for the extremely sharp immortal treasure like the seven-star sword, it is impossible for other treasures to hurt the body of the boat at all, and a teleportation circle inlaid with empty cloud crystals in the middle of the flying boat allows the aquatic beings to teleport the flying boat millions of miles away anytime and anywhere.

Of course, once the boat escapes at full speed, the speed at which the spirit stones are consumed is also amazing.

The rich are like aquatic beings, and after refining the shadowless boat, some of the rarest spiritual materials in their hands are also exhausted.

After some celebration, the three parted ways.

From Tianpeng and Liu Donghai stationed in the Black Flame Valley to leaving, nearly eighty years have passed in a flash, and in these eighty years, in addition to the boring refining tools, the three of them have exchanged cultivation experiences, and each has its own gains.

As for the six Terran Heavenly Immortal Realm cultivators who were recruited by the aquatic beings, the harvest was also very expensive, and being able to participate in the refining of the immortal treasure was itself a kind of opportunity, and the guidance of the aquatic beings on their cultivation during this period, as well as the rich reward they received after leaving the Black Flame Valley, was a great opportunity.

After a short stay in Futu Mountain for a few years, the aquatic life began to travel through the entire cold underworld, a prosperous city, and a dangerous place everywhere left the shadow of the aquatic life, during which some demons and fierce demons and traitors were ambushed by the water one after another, and even included two high-level demon lords who were famous when the two worlds of cold and red fusion fused.

Gradually, the high-ranking monks in the entire Cold Netherworld paid attention to the whereabouts of this "True Martial Ancestor", but those infamous people hid one after another, for fear that this True Martial Ancestor would come to the door.

Xuanyuan Jing and Xiaojuan have always been with the aquatic life, and they have not only opened their eyes but also tempered their minds.

However, there are a few more spiritual mountains with rich spiritual energy and a spiritual eye spring in the Demon Tower, and there is even an iceberg taken from the extremely cold land, this iceberg is composed of 10,000-year-old Xuan Ice, and the amethyst ice pith in the depths of the mountain's belly is enough to easily freeze a monk in the Heavenly Immortal Realm.

It was only after Yijiazi that the aquatic figure returned to the human race.

Immediately after, a message quietly flowed out from among the high-ranking monks of the human race, the True Martial Ancestor was going to retreat in the Futu Mountain for a thousand years, and the Great Dao of Enlightenment!

As soon as the news came out, not only those trembling treacherous people breathed a sigh of relief, but even some of the powerhouses of the big clans who were secretly worried about their courage were also relieved, it seems that this True Martial Ancestor did not have the heart to turn the Cold Underworld upside down, and the Terran race did not seem to have the ambition to continue to expand its territory.

Happy reading at the end of this chapter! (To be continued......)
