Zheng Huaiyu nodded and said, "It's okay, with your talent, I'm afraid you won't be able to take revenge in a few years." Nie Feng shook his head and said: "No, I plan to take revenge now, it is not too late for a gentleman to take revenge for ten years, and the villain's revenge is from morning to night, I think I am not a gentleman." Zheng Huaiyu shouted lightly: "Do you know how big a gap there is between you and the Little Nirvana Realm Xuan Xiu now?" He didn't think that Nie Feng would be able to kill the Little Nirvana Realm Xuan Xiu, even if Nie Feng had more means, it would be impossible to kill the Little Nirvana Realm Xuan Xiu, the gap between the Three Stars of Qi Gathering and the Little Nirvana Realm Xuan Xiu was too big.

Nie Feng said bitterly: "I didn't know before, but now I know, I just saw the power of the Little Nirvana Realm not long ago." Lan Rumeng's lips opened slightly, "Even if this is the case, do you still want to go?" Nie Feng said firmly: "If you want to go, you must go." ”

"Hey!" Zheng Huaiyu sighed, he had comprehended Nie Feng's martial arts in Nie Feng's words, it was a kind of indomitable will, knowing that once Nie Feng decided something, he would not regret it.

He said softly: "If you have anything you need, just tell us, we can only help you in this, and the points on your Blood Jade Order can also be exchanged for supplies in the treasure trove of Free City." Nie Feng's eyes lit up when he heard this, and he asked, "I don't know if there is a spatial attribute Xuan Nucleus?" Zheng Huaiyu thought for a while, shook his head and said: "No, spatial attribute Xuan Beasts are extremely rare, let alone spatial attribute Xuan Nucleus." When Nie Feng heard this, a trace of disappointment flashed in his eyes, although he didn't have much hope in the first place, but now that his hope has been completely broken, he is still inevitably disappointed.

But just when Nie Feng was extremely disappointed, Lan Rumeng said loudly: "I have a third-order spatial attribute Xuan Beast Xuan Core, which can be given to you, but your fluctuations came out, permeating the entire refining room, and then the spatial Xuan Pattern fell into the wood attribute jade basin, and the wood attribute jade basin and the outer pelvis quickly shrunk, and finally shrunk to the size of a fist." Seeing this scene, Nie Feng breathed a sigh of relief and wiped the sweat from his forehead, with his current realm and physique, there would still be sweat left, you can imagine how nervous and laborious he was just now. Nie Feng put all the things in the refining room into the sea of knowledge, the most important things are ready, he wants to go to the treasure house of Free City to take a look, what else can he get that will have an auxiliary effect on him, in the face of the powerhouse of the small Nirvana realm, it is not too much to prepare more things. He pushed open the door of the refining room and found that the sun had already set in the west, but Nie Feng still walked towards the General's Mansion after identifying the direction, and cultivators generally didn't care much about time. Of course, before leaving the refining room, Nie Feng put on a cloak, and the people in this free city were so enthusiastic that they couldn't resist even with his heart. \0\u0000After getting the spatial core, Nie Feng talked with Lan Rumeng and Zheng Huaiyu for a while before taking his leave. After saying goodbye to the two of them, he found a formation refining room in the crafting area of Liberty City, and he now urgently needed to dispose of the loot obtained this time. After entering the refining room, Nie Feng took out the Xuan Beast that he had killed from the Zhihai Space, and at the same time sorted the corpses of the Xuan Beasts and separated their muscles, skin, bones, and flesh. This was a huge project, even with Nie Feng's work efficiency, it took him ten hours of work, and after sorting all these things into categories, he felt that his whole body was no less tired than this battle with the Xuan Beast. He sat cross-legged on the floor and slept all night. The next day, after getting up, Nie Feng continued to work, he made five huge pots with the remaining jade from the last time, and then used the blood of the five attributes of gold, wood, water, fire, and earth to carve the golden array, the wood array, the water array, the fire array, and the earth array on the five basins. These five single formation methods have no power, and they are used by the materials created by the predecessors to preserve the five attributes. However, the five formations engraved by Nie Feng are unusual, these formations he portrayed have all been transformed by Xuan Tianzi, and these five formations are also the few formations that Nie Feng can depict in Xuan Tianzi's inheritance now. These five formations have been transformed by Xuantianzi, so that they can not only preserve any of the five element attribute materials, but also absorb the Xuan Qi in the void, so that the Xuan Qi becomes the corresponding attribute, and slowly enhance the things stored in the Wei Xuantian Treasure Vault The materials of the five element attributes are used in this formation. After the five huge jade basins were carved into the formation by Nie Feng, they immediately turned into golden, cyan, green, red and yellow~ colors, and slowly absorbed the Xuan Qi, turning it into the corresponding attribute to strengthen the basin, if placed here, thousands of years later, these ordinary jade basins may turn into five treasures of the five elements attributes. Nie Feng put the five basins around, and then took out the Xuan Core that had been classified and placed from the sea of knowledge space, he took out the Xuan Core of the fire attribute, and put it in the red basin, and the spiritual power turned into a needle tip and pierced it on the Xuan Core. The Xuan Core burst in response, and at the moment of shattering, the crystals were about to dissipate, but they didn't want to turn into liquid and gather at the bottom of the basin under the action of the fire array, and the silver straight lines that were about to disappear were also left at the bottom of the basin. It looked like a few silver fish swimming in the midst of flowing flames. When Nie Feng saw this scene, he breathed a sigh of relief, and secretly said in his heart: Xuan Tianzi's things are really high-quality, and even the crystals of the Xuan Core and this natural rune can be preserved. You must know that once the Xuan Core is broken, the crystals of the Xuan Core will dissipate between heaven and earth, and if the natural Xuan Pattern in the Xuan Core is not used, it will also disappear. And Nie Feng knew from the information left by Xuan Tianzi that those disappeared natural Xuan patterns were integrated into the rules of heaven and earth in that side of the world, in order to repair or strengthen the Dao patterns of that side of heaven and earth. Nie Feng saw that this formation could preserve the natural Xuan Pattern and Xuan Nucleus crystals, and he no longer hesitated, he took out a lot of Xuan Nuclei from the Sea of Consciousness, and his spiritual power turned into countless needles and pierced these Xuan Nuclei. It didn't take much time for the five pots around Nie Feng to be filled with the corresponding attributes of the Xuannucleus crystals and natural Xuanwen, and the five elements that Nie Feng harvested in the last battle Nie Feng looked at the five pots and couldn't help but sigh with emotion: "It's so beautiful!" The five pots are of different colors, but they all have corresponding lights, they look like flowing gems, and there are countless gold and silver lines swimming among the five gems, which look like twinkling stars in the starry sky.

After Nie Feng sighed for a moment, he put the five jade basins into the sea of knowledge, and then took out a lot of Xuan Beast bones and smelted them into five larger basins, which were more than ten times larger than the jade basins.

There is an inner ring in the middle of the basin, which looks like a huge mandarin duck pot, and this inner ring is just the size of the five jade pots.

After the white pelvis was made, Nie Feng carved the Life Essence Preservation Array on it, and then he took out the last bit of material and refined a Life Return Array, which was the formation arranged around the thirteenth layer of the Life Pool of the Xuantian Tower.

After everything was ready, Nie Feng took out the flesh and blood of those mysterious beasts and the remaining blood from the sea of consciousness and put them into the large array.

Under the effect of the Great Array, this blood and flesh quickly turned into a turquoise liquid, and Nie Feng controlled the turquoise liquid to be evenly divided into the five pelvises.

While pouring the flesh and blood of the mysterious beasts into the large array, he moved the liquid of life into the five basins, and finally Nie Feng gritted his teeth and put the desolate beasts in the space-time coffin into the large array, leaving only the ones that were used as bait.

However, so many mysterious beasts and desolate beasts, after turning into the liquid of life, only accounted for one-tenth of the pelvis, and judging by the color, its quality was far inferior to those natural life liquids in the thirteenth layer of the Xuantian Tower's Pool of Life.

Seeing this situation, Nie Feng gritted his teeth and said, "If I gamble all my net worth, I will not trust the genius earth treasure to smash the powerhouse of the Little Nirvana Realm." He opened the space-time coffin, and the liquid of life harvested on the thirteenth floor of the Xuantian Tower would take a long time to remove the murderous aura on his body, so as not to affect his heart by the murderous aura.

And after having this piece of Shura blood jade, he doesn't have to be so troublesome, as long as this piece of Shura blood qi is slightly refined, he can absorb the murderous qi on his body, and the refining method Nie Feng just has it, and his current strength can carve part of that set of formations.

This set of formations is different from other formations, it is composed of countless small formations, and a part of the formation can also be used normally, and when the strength is reached, it is slowly being completed, in short, this set of formations can be upgraded.

After Nie Feng exchanged the Shura Blood Jade, he looked at the remaining points, and then did not hesitate to exchange these points for formation materials that were difficult to find outside.

Looking at the empty Blood Jade Order, Nie Feng found a problem, points and the like can't be stored for long in his hands, the credits of Xuantian Academy are like this, and the hunting points of Free City are also like this.

After exchanging things, Nie Feng said goodbye and left the General's Mansion, and walked towards the Tianxiang Building opposite the General's Mansion, Lan Rumeng gave him such an important thing as the Space Xuannucleus, and when he left, he had to say hello.

As soon as Nie Feng walked under Tianxiang Tower, he saw the four daughters of Meilan Zhuju waiting for him, and after he was slightly stunned, he naturally walked over.

\0\u0000Nie Feng arrived at the General's Mansion, and after identifying himself, he was welcomed in, but he didn't see Zheng Huaiyu, and he was greeted by the four brothers who killed him in blood.

But this is normal, what kind of identity Zheng Huaiyu is, even if Nie Feng is a genius, he can't see it if he wants to see it.

After Nie Feng expressed his intentions, the bloody killing of the four people was also a refreshing person, and he directly took Nie Feng to the treasure house of Freedom City, which was in the backyard of the General's Mansion.

It is a six-story tower, standing straight where it is, showing its domineering. After Nie Feng entered the treasure house, he looked around and nodded slightly, although the formation in this treasure house is not as good as the formation of the Xuantian Treasure House of Xuantian Academy, but it is also arranged by a seventh-level formation mage, if there is someone who controls the formation, even an emperor-level powerhouse will not dare to enter this formation.

Unlike most of the materials in the Xuantian Treasure Vault, most of the things in the Liberty City's Treasure Trove are finished products, including armor, weapons, array plates, and special treasures.

But think about it, Xuantian Academy is a place where array mages gather, and most of the treasure house is naturally materials, while Liberty City is a place of war, and the treasure house is a finished product, which is really right.

But Nie Feng frowned as he looked at these countless weapons, armor, array plates, and treasures.

The wealth gathered by the three major forces of the Xuan Realm, the Dao Alliance, the Dan Dao Alliance, and the Instrument Dao Alliance every year made countless people blush, why didn't anyone make a move against them?

In addition to their own strength, there is also the fact that they will leave a back door on top of the things they refine, because they are also afraid that what they make will be used by others against them in the blink of an eye.

Therefore, leaving a back door on top of the things being refined is basically a subconscious practice of every Xuanwen master, even Nie Feng is no exception.

You can imagine how aggrieved it was to die when fighting with the Xuanwen Master, an elixir that improved its strength in a short period of time was inexplicably turned into a self-detonating pill by the opponent.

Therefore, Nie Feng would definitely not use the things refined by other Xuanwen masters, let alone Xuanwen masters of unknown origin, if he encountered a despicable and shameless Xuanwen master, it was not impossible to have a monitoring Xuanwen on the finished product.

Seeing Nie Fengzhi's frown, Blood Kill thought of Nie Feng's ability to arrange the formation with one hand, and suddenly said: "You don't like these finished products, please come with me, and I will take you to the material area." Nie Feng nodded.

The four bloody brothers took Nie Feng to a corner of this treasure house, where there was a small door, they opened the door, revealing a stone room that was only about one percent of the size of the outer treasure house, and the things inside were very messy, not as simple as the outside treasure house, it can be seen that this treasure house is basically no one takes care of it, and things are put in at will.

Bloody Kill said embarrassedly: "To make you laugh, the people in Liberty City are basically rough people, it's okay to let them dance knives and guns, they don't know anything about these things." Nie Feng walked around the treasure house, and had a general understanding of the things in the treasure house, I have to say that those big forces of the human race are still very generous, many things in the treasure house are rare treasures, and because they are from the entire human race, everything from all over the world can be seen here.
