After bestowing the merit, the Eye of Heavenly Dao gradually faded away. Dao Xuan reappeared once more.
And at this moment, Dao Xuan's cultivation had also broken through, advancing from the Early-Stage Primordial Golden Immortal to the Mid-Stage Primordial Golden Immortal.
His Dao cultivation had grown increasingly terrifying. He could command Taiji, divide Yin-Yang, transform the Three Talents, arrange the Four Symbols, grasp the Five Elements, derive the Six Harmonies, establish the Seven Stars, embrace the Eight Trigrams, traverse the Nine Palaces, and suppress the Ten Directions. With but a thought, he could unleash all manner of Great Dao laws.
Especially within his own world, Dao Xuan felt as though he were omnipotent.
As Dao Xuan traveled ever farther down the path of the World Dao, his foundations had become vastly more profound than those of cultivators at the same realm who cultivated only one law, or merely several laws.
This was the overbearing aspect of the World Dao.
If cultivated to the utmost limit, with all three thousand Great Dao laws brought to perfection and held within one's grasp, it would be simply unimaginable.
And that was indeed the case. If someone truly mastered all three thousand Great Dao laws, their realm would be identical to the Great Dao within the chaos.
In other words, that was something only the Great Dao Realm could possibly achieve.
Naturally, Dao Xuan did not dare to entertain such thoughts just yet.
However, this time, after gathering the Five-Element Spiritual Roots, his Inner World had undergone such an astonishingly violent expansion that the benefits he gained were utterly terrifying.
Though Dao Xuan's cultivation had already broken through as a result, this was merely the beginning.
As the Inner World continued to operate and evolve, he would gain even more benefits.
After all, the world's expansion was currently driven mainly by the growth of the Five Elements Law. Yet now that the world had expanded to such a scale, it would in turn benefit the other laws as well, accelerating their evolution.
Dao Xuan stood high in the sky, looking down upon his world, his heart filled with countless emotions.
Who could have imagined that he would truly reach this point step by step? From a Supreme-Grade Innate Spiritual Root, to opening up his own world, and then to evolving a world to such a degree.
If he continued onward step by step like this, might there come a day when he could reach the level of the Primordial World?
Just thinking about it made Dao Xuan's blood boil, but he quickly calmed himself.
Reaching the level of the Primordial World was still far too distant. For now, he should first evolve the Inner World into a Greater Thousand World and advance to the Hunyuan Daluo Golden Immortal!
For the Inner World to advance into a Greater Thousand World, aside from meeting the requirement in scale, the most crucial condition was to evolve one of the laws serving as the world's core laws to perfection.
Or rather, if he could not bring a core law to perfection, the world could never transform to the scale of a Greater Thousand World.
This was an unwritten rule that could not be defied.
Dao Xuan looked at his world as its ten core laws passed through his mind one by one:
Yin-Yang, Four Symbols, Five Elements, Creation, Destruction, Time-Space, Reincarnation, Stars, Karma, and Fate.
In the end, Dao Xuan settled on the law he intended to use to advance to Hunyuan. It was—
The Five Elements Law.
Although, although Dao Xuan's most fundamental law was the Four Symbols Laws.
Logically speaking, if Dao Xuan wanted to prove the Dao, he should use the Four Symbols Laws!
But note that Dao Xuan was not following the Law-Proving Dao. Although it had been mentioned before that the World-Proving Dao could also be regarded as a special form of Law-Proving Dao.
There was still a difference between the two.
And for the current Inner World, perfecting the Five Elements Law was clearly much easier than perfecting the Four Symbols Laws.
The reason lay in the Five-Element Spiritual Roots.
With the aid of these spiritual roots, Dao Xuan's Inner World could evolve the Five Elements Law much faster than other laws.
Besides, this did not mean that once the Five Elements Law reached perfection, the other laws could not reach perfection as well.
One enormous advantage of the World-Proving Dao was that it was effectively equivalent to proving the Dao again and again!
However many kinds of laws existed within the world, that many times one could prove the Dao.
And one could imagine that after repeatedly proving the Dao time and again, all kinds of perfected Great Dao laws would be added to one's body.
By then, even without using the power of the Inner World, Dao Xuan's strength would reach an unimaginable level of dominance.
Having made his decision, Dao Xuan looked over the spiritual roots again and felt that there was still more he could do.
After all, the Yang Five-Element Spiritual Roots had now been gathered, but beyond the Yang Five Elements, there were also the Yin Five Elements.
If he gathered the Yin Five-Element Spiritual Roots as well, would evolving the Five Elements Law not become even faster?
However, Dao Xuan had been able to take a shortcut in evolving the Yang Five-Element Spiritual Roots of the Inner World by making use of the Yang Five-Element Spiritual Roots that already existed in the Primordial World, saving himself much effort.
But the Yin Five Elements were much more difficult. As mentioned before, there were at least some legends concerning the Yang Five-Element Spiritual Roots in the Primordial World.
Yet Dao Xuan knew very little about the Yin Five-Element Spiritual Roots. It was no longer feasible to gather them using the previous method.
Of course, Dao Xuan had already thought of a solution.
He first flashed out of the Inner World, then returned again not long afterward.
When he returned, Dao Xuan already held a section of long vine in his hand.
This vine looked very familiar. That was right—it was the Gourd Vine. As it turned out, the Gourd Vine was one of the Yin Five-Element Spiritual Roots, the Yi Wood Spiritual Root.
Since the Gourd Vine had developed its own intelligence, Dao Xuan had not destroyed it. He even treated it as though it were a fellow Daoist.
At ordinary times, he would even occasionally expound the Dao to it and impart some of his cultivation insights.
The Gourd Vine's spirituality grew stronger by the day. It was not far from forming complete intelligence and taking human form.
The Gourd Vine and the Enlightenment Tea Tree, these two great spiritual roots, also shared an excellent relationship with Dao Xuan.
This time, when Dao Xuan asked the Gourd Vine for a section of vine, it gave it to him without hesitation.
And in this way, Dao Xuan's Inner World now possessed two Yin Five-Element Spiritual Roots.
Among them, Yi Wood was the Gourd Vine, while the other was the Moon Laurel Tree, the Gui-Water Spiritual Root!
Of course, there was actually another Gui-Water Spiritual Root—the Myriad Transformations Treasure Lotus.
However, compared to the Myriad Transformations Treasure Lotus, the Moon Laurel Tree possessed a much purer and higher-grade origin, as well as greater potential.
Therefore, Dao Xuan would focus on cultivating the Moon Laurel Tree.
After all, beyond being a Gui-Water Spiritual Root, the Moon Laurel Tree also possessed a Lunar attribute. And this Lunar attribute was related to Dao Xuan's next plan.
At present, he had the Yi Wood and Gui Water Yin Five-Element Spiritual Roots. Three remained: Ji Earth, Ding Fire, and Xin Metal.
Dao Xuan did know something about the Ding Fire Spiritual Root. During the previous Calamity Cycle, the Dragon-Han Calamity, one of the three great overlords, the Phoenix Clan, possessed a Ding Fire Spiritual Root known as the Parasol Divine Tree.
This was also the Phoenix Clan's clan-protecting spiritual root. The saying that phoenixes roost upon parasol trees referred to this spiritual root.
But given the Phoenix Clan's current situation, whether they could even preserve the Parasol Tree was a question.
Moreover, even if he added the Parasol Tree, he would only have three of the Yin Five Elements.
Dao Xuan had no desire to exhaust his wits and take enormous risks again, as he had when gathering the Yang Five-Element Spiritual Roots, just to forcibly assemble the Yin Five-Element Spiritual Roots.
After all, even in the best-case scenario, if the Phoenix Clan still possessed the Parasol Tree, Dao Xuan would inevitably have to deal with them to obtain it.
But how could the Phoenix Clan possibly hand over a Parasol Tree that was so important to them?
And as for fighting, leaving aside whether the Phoenix Clan had some powerful expert hidden away, even if he could win and seize it by force, Dao Xuan absolutely did not want to become conspicuous in Hongjun's eyes again.
