The eighteen spiritual aperture all had their own spiritual aura, Su Tang thought for a moment, and chose the big staff, and with his breathing, the spiritual spirit of the big staff turned into a little brilliance and flew away in the brain domain. Although the spirit is gone, the spiritual power it has will not disappear with it, but will be integrated into other spirits.

In the past, it was possible for other spirits to improve, but now that the level of each spirit spirit is very high, it is difficult for that bit of ablation spiritual power to have a significant effect.

It took four or five hundred breaths to collect the melting spirit, and Su Tang was a little anxious in his heart, and immediately shifted his attention to the magic sword.

The Poison Dragon Domain is not a place to stay for a long time, although Xi Xiaoru has a point, as long as the spiritual power fluctuations can be controlled, it will be difficult for other cultivators to find them, but no one knows when the danger of the Dao will come. Once discovered, Xi Xiaoru will definitely fall into a passive situation, if the other party is more clever and uses him Su Tang to blackmail, the situation will be critical.

Xi Xiaoru's personality is strong, in fact, Su Tang is the same, he is unwilling to drag Xi Xiaoru down.

Unexpectedly, the process of refining the Demon Sword was very easy, in Su Tang's estimate, it was less than two thousand breaths, and the spirit of the Demon Sword had already been formed, which was too much worse than the time it took to refine the Demon Heart.

Something is wrong...... The more powerful the spiritual power possessed by the spirit weapon, the longer it will naturally take, and the magic sword can turn an ordinary dumb slave into an extremely fierce one, it should definitely not be so easy, what is missing

Su Tang suddenly remembered what Xiao Buregret had said, the boulder with the magic sword was very weird, densely covered with countless black silk threads, it might have been formed by the extravasation of the magic sword's spiritual power, could it be ...... When the dumb slave pulled out the magic sword, what spiritual power did he draw?

Perfect Spirit, Magic Sword, Level 3.

What's more, when refining the Demon Heart, the spirit of the Demon Heart is the fourth level of perfection, only one level short, how can it seem empty, not even a little light?

Su Tang tried to activate the spirit, and at this moment, there was a roar in his brain, and the spirit of the magic sword seemed to suddenly explode, and countless black smoke spread in all directions, and wherever the smoke spread, the spirit would become dim, as if it had been corroded.

Su Tang was shocked, and the remaining seventeen spirits were all activated, and he tried to stop those smokes

The spirit of the magic sword was trembling, and Su Tang faintly heard the sound of wild laughter, but he didn't bother to think about how the wild laughter came out, and tried his best to control the other spirits.

The smoke emitted by the spirit of the magic sword became more and more, at first, it was just like a diffuse mist, but it didn't take long for the smoke to condense into endless darkness, and Su Tang could only sense the existence of the spirit, but he couldn't see anything.

Su Tang was horrified, he knew that if he lost control of the brain domain, he would become like a dumb slave

In the outside time, nearly ten hours have passed, Xi Xiaoru, who was sitting still, suddenly felt something, looked sideways at Su Tang, and found that a black liquid flowed out of Su Tang's nostrils and eyes, she hurriedly stood up and took a closer look, but she didn't know if this was a deviation or a normal phenomenon, after all, Su Tang had never talked to her about this before.

Su Tang's resistance was fragile, the thick darkness was condensed like substance, his reason gradually became muddy, one moment, he was still trying to stimulate his spirit, the next moment, he forgot what he was going to do, only knew that there was an urgent matter that had to be done, but he couldn't think of anything.

Su Tang's face became more and more gray, no matter what kind of desperate situation he faced, if he could keep his sanity, he would always struggle, but if he didn't even have his senses, it would be equivalent to complete defeat, and it would be impossible to turn the tables around.

Xi Xiaoru found that Su Tang's face was wrong, and reached out to pat Su Tang's shoulder, but hesitated again, the magic sword had disappeared, shouldn't Su Tang have succeeded? Wait...... If you are disturbed in the retreat, you will definitely suffer from spiritual backlash, if Su Tang is fine, then isn't he plotting to kill Su Tang?

Su Tang definitely did not lack the courage to confront despair, but he didn't know what he wanted, and the confrontation naturally did not exist.

Suddenly, a huge towering ancient tree appeared in Su Tang's mind, no matter how thick the darkness was, it couldn't hide its figure, so that Su Tang instantly regained his clarity, by the way, the spirit of the magic sword was strange

Airplanes...... The towering ancient tree was trembling, and countless giant leaves were slowly falling, each giant leaf could take away a wisp of darkness, making Su Tang's brain domain clearer and clearer.

However, the leaves of the towering ancient tree were numbered after all, and the spirit of the magic sword was still emitting smoke, and I don't know how long it took for the shadow of the towering ancient tree to begin to blur.

The next moment, Su Tang suddenly fell into a trance, and then, an old man appeared in front of him.

"This spiritual refining method, a total of eighty-one articles, can open eighty-one spiritual apertures, and when the merit is completed, even if the gods and demons of the heavens are satisfied, you must let you have a few points. The old man seemed to be speaking to him.

"Old Ancestor, can the art of spiritual refining be immortal?" This question came from his Su Tang's mouth.

"If the spirit does not fall, the body will not be destroyed, and you will live forever, you are willing to learn?"

"I am willing to learn, I am willing to learn, thank you for the cultivation of my ancestors" Su Tang could feel that he was extremely happy.

The old man's hands waved, and strange golden talismans appeared in the air, bombarding the depths of Su Tang's mind one after another, and the flickering golden light wiped out all the darkness.

Then the figure of the old man vanished, and everything seemed to be nothing.

Su Tang heard the sound of wild laughter again, and the spirit of the magic sword was still emitting smoke.

Do you want to repeat what you just encountered?

Su Tang also laughed, the spirit refining method was taught to the Ancient Tree of Destiny by that unknown and incomparably powerful existence, and fused with the Ancient Tree of Destiny, he could refine the spirit weapon, but that was only the most basic ability.

Every golden rune that the old man punched into his brain domain was vast and boundless, and this was the true inheritance

It doesn't matter if you are the aura cultivated by the magic sword for thousands of years, or the remnants of the will of Ren Yukou are at work, come on, he has been inherited, the spiritual aurture is his, the spiritual spirit is his, and the brain domain is also his, and no one can defeat him here

Now Su Tang understands that opening the spiritual aperture and refining the spiritual spirit is just the beginning, just like the reincarnation of yin and yang, there are more and more spiritual spirits, this is released, so it will naturally be collected in the future.

There are nine turns in the art of spiritual refinery, ninety-nine into one, Fang Shi is complete, and now he is about to break through the first turn.

Su Tang's mind worked, and the spirit of the fixed light sword slammed straight towards the magic sword.

Rumble...... In the violent shock, the two spirits merged into one, and the wild laughter that was faintly heard just now turned into a terrible wail.

Perfect Spirit, Magic Sword, Level 5.

Su Tang used his mind again, and the spirit of the chain knife then crashed into the magic sword.

Rumble...... There was another wail from the spirit of the magic sword.

Perfect Spirit, Magic Sword, Level 6.

Hu Lishan's sword is only an eighth-level spirit, so I don't want it

After another fusion, the perfect spirit, the magic sword, level six.

Could it be that the spiritual power contained in the eighth-level spirit is too low? Then there is another eighth-level one, and I don't believe it or upgrade

The spirit of the short iron rod also fused with the spirit of the magic sword, and sure enough, the magic sword was upgraded and became a perfect seventh level

That doesn't work...... The number of nine turns is the rule, it is fused four times, and there are still four chances left, plus the magic sword, which is exactly nine turns.

The next moment, the spirit of the Dark Sky Hammer flew towards the magic sword, booming ...... The spirit of the magic sword exudes a dazzling brilliance, and the Dark Sky Hammer is the perfect spirit, making the magic sword rise to the next level again.

Again, the Flying Rainbow Sword is a perfect spirit level two, and I don't know what effect the Dao will have.

Rumble...... Perfect Spirit, Magic Sword, Rank 9

The mournful wails in the magic sword grew more and more, and had turned into a whimper.

There are still two Su Tang who chose the sword of Taizheng, and he was a little hesitant, because the sword of Taizheng was the object of love between him and Xi Xiaoru, but ...... Let's get out of the way

Rumble...... Perfect Spirit, Magic Sword, Rank 9.

Perfect Ninth Level is the highest? Su Tang has already come to the temperament, the Ninth Perfect Spirit, the Sunset Sword, and I don't want it, I don't believe in the Demon Sword Spirit of the Nine Revolutions, and it is still not under his control

Rumble...... The spirit of the magic sword skyrocketed, and if the other spirits and spirits were bright or dark stars in the night sky, then the magic sword became a golden morning sun, and where the light swept through, it was enough to sweep everything.

Waves of scarlet blood were squeezed out of the spirit of the magic sword, and then they were swept away by the golden light

Yuanluo, magic sword, level 1

Su Tang took a long breath and suddenly opened his eyes, Xi Xiaoru, who was squatting in front of him, was startled, and his body involuntarily fell back, Su Tang's eyes turned golden, as if there were two small suns shining inside.
