A ray of cyan colored light shot out from Xu Ruqing's cave. After circling in the air for a while, it revealed the figure of the person inside, who else could it be but Xu Ruqing.

"This guy, he actually hasn't stopped the circulation of the Sky Fire Array, could it be that he's refining a piece of sacred material? But looking at his wooden body, he doesn't seem like a person with a sacred material! "Whatever, since you haven't come out for half a month, you can't blame me for that, haha!"

Looking at the black and white light in the air that had yet to disperse, Xu Ruqing muttered to herself. Her body moved, transforming into a streak of green light as she arrived at the mouth of the cave.

After arriving at the cave entrance, the storage bracelet in Xu Ruqing's hand shone with a brilliant light, and a large amount of green array flags appeared in her hands. After taking out the array flags, Xu Ruqing used her spirit power to activate them, followed by the True Essence in her body.

"Rising Wind, Formation complete!"

After spending a bit of time and effort to send 81 array flags flying all over the ground, Xu Ruqing formed a seal with her hands and formed a seal in the air, following that, the 81 array flags all around lit up with green spirit light, and countless green symbols appeared together with the cyan light. These symbols interweaved in the air, and instantly transformed into a large array.

This Gale Tornado Array of mine has undergone many years of study and improvement. Forget about trapping True King Rankers, even if I were to be trapped in there, it would not be easy for me to escape from it with my normal Tongxuan experts. Stupid wood, make me angry, if I don't teach you a lesson, you would think that I'm a vase!

After Xu Ruqing said this, sshe took out her seven-storey ice tower from her bracelet of holding with a complacent look. After taking out her ice tower, he threw it into the Gale Tornado Array, and then used both hands to form a few seals, causing the imposing Gale Tornado Array to become invisible under the flickering green light, as though it had never appeared before. After finis.h.i.+ng all of this, Xu Ruqing nodded her head in satisfaction, then turned into a ray of green light and returned to her own cave.

Li Mu naturally did not know anything about the arrangements for Xu Ruqing at the entrance of the Wine Spirit Cave. At the moment, he was weakly urging his own flames of Quintessential Essence to condense one of the Big Yellow Seal s in the flames in front of him.

In this half a month, Li Mu had refined two-thirds of the black iron on his body into the initial stage of the huge seal. This huge seal was created using the copy of the Heavenly Spirit Treasure that Ren Xiaoyao had left behind in the jade scroll, and although Li Mu's black iron was very different from the copy of the replica, and even though he still lacked a lot of supplementary materials, the difference wasn't too great. After all, black iron were rarely seen Sacred Level materials, and Li Mu had even used two-thirds of them.

"Heaven and Earth are limitless, there are Daos in myriad magics, Chaos is formed, congeal!"

Suddenly, Li Mu bellowed, and then, his two hands formed an extremely strange hand seal, this hand seal was something Li Mu learned from imitating the refining method of the Chaotic Seal, he spat out a few drops of blood essence and with a thought, the blood essences merged with his hand seal, forming a hand seal that was constantly flickering.

Following the formation of the seal, Li Mu's consciousness moved, raising his hand towards the seal formed by the black iron, Li Mu formed a seal of his own.

Finally, the upper half of the seal condensed into nine yellow heavenly dragons. The nine yellow celestial dragons circled around the Big Yellow Seal, and the nine dragon heads protected a yellow dragon pearl in the center. At the same time, on all four sides of the Big Yellow Seal, the diagrams of the Azure Dragon, White Tiger, Vermillion Bird, and Black Tortoise respectively appeared.

The Big Yellow Seal that looked somewhat rough right after the Four Symbols and Sky Dragon formed, became much more n.o.ble and generous. Seeing that, Li Mu was overjoyed, although he was only an imitation of the Seal of Primal Chaos that was refined, but its appearance did not look much different.

The next step is to inscribe a spell formation. There are a total of seventy-two seals for this replica, but some of the formations are too complex and complicated, it would take at least ten to eight years for me to master all the techniques, but in any case, the black iron will be able to refine them again in the future, so I will first engrave eighteen of them into the simpler ones.

After successfully modeling the Big Yellow Seal, Li Mu muttered to himself, he bit his own fingertip, and a drop of blood essence flowed out. The True Essence in his body circulated, and carved an array in the air, it used True Essence and Blood as materials to condense the array formation, and was also a method used by many Spirit Treasures, the only difference was, the complexity of the array formation was different, every array was formed of symbols, and all of the different array formations had different effects, for example, the first array formation Li Mu was inscribing was the Universe Heaven and Earth Will Formation, the so called Universe Formation Formation Formation Formation was controlling the change in size of the Spirit Treasure.

Very quickly, under the guidance of Li Mu's powerful consciousness, a blood red formation formed in front of him. Li Mu lifted his hand, and with a point of his finger, the formation flew into the Big Yellow Seal that was still being tempered by the dao flame.

After the Big Yellow Seal absorbed the blood formation, its entire body flashed with light, and quickly returned to normal. There was not a single trace of blood on its body, making it look rather marvelous.

It did not take Li Mu much time to create eighteen formations. A few hours later, Li Mu inserted the last of the eighteen formations into the Big Yellow Seal, and with a thought, both the Sky Fire Array and the Earth Fire Formation closed up at the same time. The streaks of fire in the air instantly lost their supply of heavenly fire and earth fire, and Li Mu's true essence fire was still burning.

"Half a month's time. As for success!" "Hahahaha!"

After withdrawing the Earth Fire and Sky Fire Array, Li Mu laughed complacently. A wisp of his primordial spirit was separated from his forehead, and he fused it into the Big Yellow Seal that was enveloped by his flames of true essence.

After the fusion of his primordial spirit and the Big Yellow Seal, Li Mu instantly formed a mental connection with it, this spirit treasure that took a lot of his energy to create could finally be considered as a success.

Li Mu used his Spiritual Sense and the Great Brahma Seal that was originally four to five metres wide immediately shrunk to the size of a fist. With a wave of his hand, Li Mu caused the Great Brahma Seal to spin in midair and fly towards him.

"In the end, it was a formation left behind by a copy of the Heavenly Spirit Treasure, it is profound enough, I had to spend two-thirds of the black iron to refine it, and its weight is more than two million jin. In the Dao fire, with the support of the Heaven Fire Earth Fire Formation, it should not be impossible to endure, and now that it has landed in my hands, it is as light as a feather, it is truly profound."

Although this Great Brahma Seal looked simple, the eighteen array formations that were incorporated into it had huge origins. Among them, there was the Universe Ruyi Formation that could control sizes, there was also the Small Void Formation that could control weights, there was also the array formation that could increase attack and defense, there was even a formation that could increase attack speed and strengthen the control of Spiritual Sense, etc.

On the contrary, there was a large pile of them scattered about. However, Li Mu could clearly feel that the formation in the jade scroll that he obtained from Ren Xiaoyao was very different from the one that was normally used in the cultivation world to refine weapons.

For example, the Universe Ruyi Formation, was used to control the size of the formation while the cultivation world normally used it to control the size of the formation, but it could at most enlarge or shrink the spirit treasure ten times, but Li Mu himself knew that the body of the Great Brahma Seal, which was only four to five meters wide, could enlarge to the size of a mountain. This difference was not ten or twenty times.

Looking at the Great Brahma Seal in his hands, Li Mu had the urge to go out and fight with someone, but he resisted the urge himself, because he had only completed half of the mission, and had yet to make use of the remaining one-third of the black iron.

Li Mu shrunk the Great Brahma Seal in his hand into a ray of yellow light and then swallowed it into his middle stomach. At the same time, he kept his own Yuan Dan inside his stomach, he was not planning to leave, and prepared to rest well for a few days, then continue refining his second treasure.
