《The Twelve Dutian Gods and Demons》 was most suitable for Jiang Xuan's cultivation.

Because of this, although 《The Twelve Dutian Gods and Demons》 could only create twelve clones, it was best suited for Jiang Xuan's cultivation.

Now that he was still in the Heavenly Immortal realm, using some immortal pills would be enough to master the first level. It was very easy to get started with this divine power secret technique. After all, the first level came at the cost of reducing the strength of the original body. The original body was divided into twelve, and each clone's strength was reduced to one-twelfth of the original, so it was naturally the easiest. As long as there were some immortal objects to assist, it could be cultivated.

But the second level would be a thousand times more difficult, because various rare objects were hard to find, and they were also very valuable. It would not be easy to find them all.

Fortunately, the rare objects required for the second level of 《The Twelve Dutian Gods and Demons》 could be found in the Three Realms. Although they were considered rare and precious, Jiang Xuan was now only in the Heavenly Immortal realm, so he didn't need to consume too much to cultivate it. Moreover, he also had the skill of alchemy. Even if the treasures on his body were not enough to exchange for enough rare objects, he could also use the skill of alchemy to exchange for them.

As for the third level, it not only required rare objects, but also required comprehension. It was even more difficult to cultivate. Of course, Jiang Xuan didn't have much else, but he had a lot of "himself." This kind of method was very useful to all Jiang Xuan, just like the 《Chaos Gang Dou Sutra》 back then. At that time, all the versions of him in various worlds would deduce it together, and it would be strange if he couldn't cultivate the third level.

Of course, it was not convenient for Jiang Xuan to leave the Underworld now, so he contacted Ao Yu and asked him to inquire in the Shennong Dojo which of his subordinates had the rare objects he needed, and then exchange for them in Jiang Xuan's name.

"The first level is the simplest, so I will cultivate the first level first, so that I can do more things."

Jiang Xuan thought to himself, after dividing into twelve, although he only had one-twelfth of his current strength, his own cultivation had reached the threshold of the Heavenly God True Immortal. Even if he divided into twelve, he would not be too weak, and he would still be a top expert among Heavenly Immortals.

For example, he could have several clones handle Underworld affairs together, and other clones could refine immortal pills, or even Pure Yang Immortal Pills, without delaying either side.

Thinking of this, Jiang Xuan also directly began to cultivate. As he circulated the method of 《The Twelve Dutian Gods and Demons》, he saw black and white threads begin to condense on his body surface, interlacing with each other, gradually condensing into mysterious runes.

As time passed, there were more and more runes on Jiang Xuan's body surface. In the blink of an eye, he seemed to be wearing a robe of chaos, with mysterious auras emanating from the black and white runes.

Buzz buzz buzz~~~

A large number of chaotic runes began to interweave with each other, and then seemed to turn into flowing water, actually flowing on Jiang Xuan's body surface, causing many runes to gradually merge.

Boom!

With the flow, these countless runes finally merged into a cocoon of chaotic color, completely wrapping Jiang Xuan. The mysterious power of the runes in the cocoon instantly invaded Jiang Xuan's Heavenly Immortal body.

The true mysteries began to gradually appear at this moment...

At this moment, Jiang Xuan only felt himself in a daze, but he could still sense that his true spirit was gradually separating, one part, two parts, three parts... each part was neither more nor less, exactly one-twelfth of the complete true spirit of the second primordial spirit.

His divine soul also began to split, and at the same time, he could feel his own power beginning to weaken and deplete. The immortal pills that he had prepared long ago were also constantly being taken by him.

In a daze, he didn't know how long had passed.

The Jiang Xuan in the Yama Palace suddenly transformed into twelve cocoons of chaotic color. Immediately afterwards, the twelve cocoons gradually dissipated, and a figure appeared in each of them, all sitting cross-legged, with completely identical auras, and even completely identical strength and cultivation.

Moreover, all twelve clones could be regarded as the original body. Even if one of them died, it could quickly condense again, and it would not damage the divine soul like ordinary clones.

This was equivalent to directly having twelve lives, and as long as one body did not die, the other clones could continue to condense!

"It's done. This kind of method is really mysterious." Jiang Xuan sensed the changes in himself and couldn't help but sigh, "Each one has a complete true spirit, divine soul, and even the Chaos Golden Core in the body, although they are only one-twelfth of the original, they are still extraordinary."

Jiang Xuan was overjoyed. The Golden Core world in his body, also known as the Chaos Golden Core, was his true trump card. With the existence of the Chaos Golden Core, as long as he could continuously expand the world within, even without the help of rare objects, his cultivation would sooner or later return to its peak.

Of course, that would definitely be an extremely long process. Jiang Xuan didn't have so much time to wait now, so he naturally wouldn't choose this method. If he could quickly cultivate the second level, he would naturally not waste time.

Soon, Jiang Xuan also began to divide the work. Six clones handled Underworld affairs. Although the intensity of divine sense and divine soul had decreased, the six clones were of one mind and cooperated seamlessly, so the speed was not slow.

More importantly, the other six clones could free up their hands to refine immortal pills, and even with his current cultivation, refining Pure Yang Immortal Pills was not a big problem.

As for the medicinal materials, there were countless precious medicines and divine medicines outside the Hundred Herbs Hall. Anyway, the Hundred Herbs Hall also had rules that 30% of the pills refined with the medicinal materials of the Hundred Herbs Hall could belong to him. Although it was not much, refining more would always be enough for him to trade for rare objects.

Because of this, Ao Yu was also running back and forth. As long as someone was willing to trade rare objects, after agreeing on the price, he would go to the Hundred Herbs Hall to pick enough precious medicines, and then send them to the Underworld for Jiang Xuan to refine. Then he would give 70% to the Hundred Herbs Hall, and take the rest to trade.

Fortunately, there were many strong people in the Shennong Dojo, and each of them had a lot of background, so trading was not too difficult.

Moreover, Jiang Xuan was originally of the Shennong lineage, and he was also a disciple of Qing Fan Xianzi (Azure Lotus Fairy), so they were of the same faction. And since he didn't take advantage of them, those who had rare objects were naturally willing to trade.

Therefore, Jiang Xuan only used half a year to exchange for the rare objects needed to cultivate the second level. Then, six clones cultivated the second level first, while the other six clones continued to handle Underworld affairs.

Cultivating the second level required three kinds of rare objects, which could improve the cultivator's divine soul, mana divine power, and immortal body strength. After all, they were divided into twelve, and their strength decreased, so if they wanted to quickly restore to their original level of strength, they naturally needed corresponding rare objects.

At this time, there were three clusters of precious light floating in front of each clone, and Jiang Xuan's mana was absorbing the essence from them. At this moment, Jiang Xuan's immortal body, including his soul, seemed to be washed.

He also immediately used the method of 《The Twelve Dutian Gods and Demons》, guiding the energy of the rare objects, and tempering his own divine soul, immortal body, and Chaos Golden Core bit by bit.

The effect was also very direct. The strength of the immortal body and divine soul was like a seedling, gradually growing, about to become a towering tree. And the world within that Chaos Golden Core was also expanding under Jiang Xuan's guidance, transforming towards the size it should have been.

At the same time, the aura of the six clones was getting stronger and stronger, gradually approaching the critical point between the Heavenly Immortal and the Heavenly God, about to completely cross over, but it was still a little short.

"It's done."

Jiang Xuan opened his eyes. The strength of these six clones had reached the original level of the second primordial spirit, and the Chaos Golden Core world in their bodies had also returned to the extent of a Small Chiliocosm again.

After that, they also exchanged with the other six clones, allowing those six clones to cultivate the second level.

Before long, the other six clones also successfully cultivated. At this moment, all twelve clones had the original strength of the second primordial spirit, and all of them could be regarded as the second primordial spirit's main body. Even if one of them died, the other clones could quickly condense it again.

"Now, I can be considered to have some ability to protect myself."

In these Three Realms, let alone if he had only reached the threshold of the Heavenly God True Immortal, even if he was a true Heavenly God True Immortal, he was nothing. In that final battle, the number of Heavenly God True Immortal deaths was in the tens of thousands. Without becoming a Dao Ancestor, he could only be considered cannon fodder after all.

And even if he became a Dao Ancestor, if he didn't reach the level of a leader, he wouldn't be much better off in the final battle, and he could still die at any time.

The current Jiang Xuan could only be said to be a slightly larger ant. Even the original body, after sharing the power, could not stand at the peak of the Three Realms. However, cultivating the first two levels of 《The Twelve Dutian Gods and Demons》 could be said to have some ability to protect himself. At least, it was very difficult to completely kill him.

"I'm not in a hurry for the third level, and even if they merge, they may not be comparable to a first-class Golden Core Heavenly Immortal."

Ji Ning, after successfully cultivating the 《Eighteen Divine Demons of Tao Wu》, was only comparable to a first-class Golden Core after the eighteen clones merged. Moreover, at that time, Ji Ning's Golden Core had already been upgraded to the second class, which was at the same level as the current Jiang Xuan.

Therefore, even if Jiang Xuan cultivated the third level now, it would be difficult to upgrade the Chaos Golden Core world to the extent comparable to a first-class Golden Core, so he was not in a hurry for the time being.

Moreover, his Chaos Golden Core was different from ordinary Golden Cores. Even if he didn't cultivate the third level, he could continuously improve his strength by expanding the Golden Core world, and it was not impossible to even transform the Chaos Golden Core in each clone's body to the extent comparable to a first-class Golden Core.

"Twelve clones can do a lot of things. It's enough to leave one clone in the Underworld. As for the other clones..."

Jiang Xuan pondered secretly. The second primordial spirit cultivating 《The Twelve Dutian Gods and Demons》 could definitely not be hidden. The Underworld could not isolate the Heavenly Dao, so it was impossible to hide it from the Heart Devil Dao Ancestor.

Therefore, what he could do now was how to maximize his own advantages. Before accumulating enough power, he had to ensure his own safety. At least, he had to ensure that at least one clone survived at all times.

The Underworld could be considered a place where there would be no danger in a short time. The current Wu Jian Sect (Seamless Gate) would not be crazy enough to forcibly attack the Shennong World Domain because of him alone, nor would they send a Dao Ancestor to deal with him, a small Heavenly Immortal.

As for the other place, it was naturally the Slanting Moon Great World. That was Bodhi Dao Ancestor's territory. Without Bodhi Dao Ancestor's permission, even other Dao Ancestors could not find it. A clone hiding in it would be absolutely safe, but now it would be a little troublesome to go back. He could only contact his other senior brothers to see.

As for the other clones, he had already thought about it. One would return to the Tianyu Great World, one would return to the Shennong Dojo, one would go to the Great Xia World, and as for the other seven, they would travel to the Three Thousand Worlds to experience the mortal world and seek opportunities.
