Chapter 681: Millennia Pass

The smooth opening of twelve particle worlds meant that Lin Yuan could continue walking down this path.

Being able to open and maintain twelve particle worlds meant he could open and maintain one hundred and twenty particle worlds, 12.0 billion particle worlds, and even infinite Ganges-sand particle worlds.

But at the same time,

another problem would arise.

That was resources.

The opening of worlds was not done out of thin air.

It required a large amount of resources to support it.

Compared to the Internal World and the Universe, particle worlds were much smaller, and their consumption of resources would also be significantly reduced.

But the sheer number was overwhelming.

Now that only twelve particle worlds had been opened, Lin Yuan could still support it, but what about one hundred and twenty particle worlds? What about twelve hundred particle worlds?

"Qingyun Saint Sect?"

Lin Yuan thought of his own Sect. As a hegemony-level force before the great upheaval of heaven and earth, even though the Qingyun Saint Sect had declined through successive attacks on the mountain by great demons, its foundation remained very deep.

If Lin Yuan obtained all the resources of the Qingyun Saint Sect, it could indeed support the opening of particle worlds for a very long time.

But that was treating the symptoms rather than the root cause.

Even if the total resources of a single Qingyun Saint Sect could support him in opening up to twelve hundred particle worlds, what then?

Where would he get the resources to open twelve thousand particle worlds or one hundred and twenty thousand particle worlds?

Regardless of how it was put, the Qingyun Saint Sect was also the Sect of his original body, and Lin Yuan was not willing to demand too much.

"I still need a stable channel to obtain a large amount of resources,"

Lin Yuan thought to himself.

In terms of resource richness, this Origin World was naturally the Central Heaven, but nowadays the Central Heaven was the place where Devilish Qi was most dense, and the traces of the Source Demon were often found there.

Before his strength had recovered to its Peak, Lin Yuan was not very willing to go over.

Even if his strength recovered to its Peak, if he had no means to deal with the Source Demon, Lin Yuan would still be reluctant to go.

"Gate of Myriad Realms."

Lin Yuan thought of sending resources from the First Source World for his own Cultivate.

He had an extraordinary status in the First Source World. Even the Six Ancestors bowed and befriended him. Getting enough resources to open particle worlds would not be a big problem.

But the key was that using the Gate of Myriad Realms as an "intermediary" to send items to another dimensional space required paying the price of Boundary-Breaking Source Power.

For example, during his several traversals before the Twelfth Order, Lin Yuan often teleported the Origin Bell and the Mysterious Gourd to the traversed worlds for his own Cultivate.

Of course, this consumed a few wisps of Boundary-Breaking Source Power during the process.

A few wisps of Boundary-Breaking Source Power were indeed not much, but it was limited to sending just two items: the Origin Bell and the Mysterious Gourd.

If the quantity of items increased or the "quality" became larger, the consumed Boundary-Breaking Source Power would naturally rise accordingly.

Furthermore, the resources consumed by Lin Yuan to open particle worlds were more like mountains and seas. Relying solely on the Gate of Myriad Realms to send them over, the consumed Boundary-Breaking Source Power would probably have to be calculated in millions or tens of millions of wisps.

"Forget it then."

Lin Yuan shook his head slightly.

How much Boundary-Breaking Source Power had he painstakingly accumulated until now? Every wisp was highly valued. If he had to consume so much Boundary-Breaking Source Power just to open particle worlds, Lin Yuan would rather directly Cultivate in the First Source World.

"The resources for opening particle worlds still have to be placed on this Origin World."

Lin Yuan thought to himself. Sending resources through the Gate of Myriad Realms had a price that was simply too high, so high that Lin Yuan did not want to pay.

"The resources of this Origin World."

Lin Yuan looked up outside the Qingyun Sacred Mountain. Ever since the great upheaval of heaven and earth, what was the most abundant thing in this Origin World?

Devilish Qi.

Omnipresent Devilish Qi.

"Devilish Qi?"

Lin Yuan's expression turned slightly solemn. He had studied Devilish Qi before and determined that this was a very high-end power. Otherwise, once those who fell into demonic deviation began to be assimilated by Devilish Qi, their strength would not surge immediately.

But Lin Yuan had never tried whether Devilish Qi could be converted into energy and then absorbed and devoured.

Because countless Experts in this Origin World had already tried it long ago; Devilish Qi could not be absorbed. Once forcibly absorbed, one would be assimilated by Devilish Qi and thus become a person who fell into demonic deviation.

As long as they were practitioners, everyone knew about the hidden dangers of those who fell into demonic deviation.

With the increase in the degree of demonic deviation, the emotions of those who fell into it would gradually be worn away, until finally their memories were rapidly erased, turning them into a powerful 'demon' resembling a walking corpse.

"Just because the practitioners of this Origin World cannot absorb Devilish Qi does not mean that I cannot absorb Devilish Qi."

Lin Yuan's thoughts moved slightly, and a wisp of deep power intertwined between his fingertips, which was precisely Devilish Qi.

Outside the Qingyun Sacred Mountain, overflowing Devilish Qi was everywhere. It was effortless for Lin Yuan to obtain a wisp of Devilish Qi.

"Absorb?"

Lin Yuan carefully observed this wisp of Devilish Qi.

Direct absorption definitely wouldn't work.

Devilish Qi would directly erode the mental will.

Although with the strength of Lin Yuan's mental will, he could completely block it, there was no need to ask for trouble.

"Chaotic Yin-Yang Taiji Diagram."

Lin Yuan's thoughts moved slightly, and a Taiji diagram composed of one Yin and one Yang appeared before him.

As the Chaos power path evolved by Lin Yuan himself, it only required a single thought to directly gather and urge it.

Buzz, buzz, buzz.

The black and white Taiji diagram rotated, vaguely beginning to penetrate the overlapping space and time in all directions.

Lin Yuan directly placed that wisp of Devilish Qi beside the Chaotic Yin-Yang Taiji diagram.

The Chaotic Yin-Yang Taiji diagram had one Yin and one Yang, one black and one white, devouring that wisp of Devilish Qi like a millstone.

The Chaotic Yin Yang Taiji Path originated from Chaos and possessed the ability to transform all things into Chaos.

Seeing that wisp of Devilish Qi being devoured by the Chaotic Yin-Yang Taiji diagram, it was continuously crushed by the black and white millstone.

However, after being crushed, the essence of the Devilish Qi remained unchanged; it was still Devilish Qi.

Then it was crushed again.

After repeating this hundreds of times, that wisp of Devilish Qi finally transformed into a certain pure power.

"Is this the essence of Devilish Qi?"

Lin Yuan's eyes lit up as he carefully observed this wisp of pure power.

"Let's see."

Lin Yuan immediately began to absorb it.

"It can be absorbed and refined."

"It is very suitable for opening particle worlds."

A smile appeared on Lin Yuan's face. In this way, the biggest problem in his opening of Ganges-sand particle worlds—insufficient resources—was resolved.

"It's just that after a wisp of Devilish Qi returned to its Origin, the pure power formed was simply too little."

Lin Yuan thought to himself that the resources consumed by opening Ganges-sand particle worlds could not be supported by just a few wisps of Devilish Qi.

"It seems those demons…"

Lin Yuan's heart stirred slightly. The so-called demons were essentially nurtured by dense Devilish Qi, and the demon itself was an aggregate of extremely high concentration of Devilish Qi.

It could be predicted that the 'demons' refined by the Yin-Yang Great Millstone could provide Lin Yuan with pure power far exceeding a few wisps of Devilish Qi.

"I'll go out and try it right now."

Lin Yuan's heart moved slightly, and he immediately left the Qingyun Sacred Mountain quietly.

During these past few years in the Qingyun Institute, with Lin Yuan's Heaven-Defying Comprehension Ability, he had long thoroughly studied the Sect-protecting grand array of the Qingyun Sacred Mountain.

Not to mention entering and leaving the Qingyun Sacred Mountain soundlessly, even directly mastering the entire Qingyun grand array was a breeze.

Outside the Qingyun Sacred Mountain.

Devilish Qi drifted around.

Lin Yuan searched carefully and finally discovered a demon spirit.

Although the size of this demon spirit was not as towering as that great demon that attacked the mountain, it was still as large as one million miles, crouching there and quietly breathing in and out the Devilish Qi between heaven and earth.

Not every demon liked to wander around; many 'demons' were more willing to stay in a certain place and slowly breathe in and out Devilish Qi.

"It's you."

Lin Yuan looked at that demon spirit. A demon spirit with a size of one million miles? How many wisps of Devilish Qi did it contain?

Not to mention that the composition of a demon spirit was inherently an aggregation of high-concentration Devilish Qi. Once such a demon was refined by Lin Yuan, he didn't know how much resources it would be equivalent to.

"Quick battle, quick decision."

Looking at the massive demon spirit not far away, Lin Yuan directly operated the Chaotic Yin-Yang Taiji diagram to suppress it.

"Roar!!"

This demon spirit was originally sleeping soundly, but suddenly felt its behavior of breathing in and out Devilish Qi interrupted, and instantly became angry.

'Demons' did not have thoughts, but they possessed simple ideas and notions, such as curiosity? Or anger?

The so-called great demon attacking the mountain was just a great demon developing curiosity about the Qingyun Sacred Mountain, then trying to attack it, and later finding no changes, losing interest and turning away.

"Suppress!"

Lin Yuan urged the Chaotic Yin-Yang Taiji diagram. As a Disciple of the Qingyun Saint Sect, the original body itself possessed Eleven-Tier Peak strength. Over these past few years since Lin Yuan took over the Cultivate, his true strength had long recovered to the Sovereign Realm.

With the strength of the Sovereign Realm urging the Chaotic Yin-Yang Taiji diagram, let alone a mere demon spirit, even a great demon would have to flee in defeat.

After a while,

this million-mile-large demon spirit was suppressed by Lin Yuan.

"Refine."

Lin Yuan put the demon spirit into his Internal World, then urged the Chaotic Yin-Yang Taiji diagram to continuously crush it.

Swish, swish, swish.

The demon spirit's huge demonic body rapidly shattered and soon turned into the purest power, which was quickly absorbed by Lin Yuan.

"Right now, I am actually quite similar to those who fell into demonic deviation."

While devouring and absorbing the refined power transformed from Devilish Qi, Lin Yuan thought to himself.

It was just that while both devoured demonic entities, what Lin Yuan absorbed was the demonic entity crushed into the purest state by the Chaos Taiji Great Millstone, which would not cause any impact on himself.

In fact, judging by the methods of this Origin World, there must be similar methods to refine demonic entities like Lin Yuan did and then absorb them.

However, once Devilish Qi was transformed into the purest power in this way, it would not have that effect of rapidly boosting strength.

What the practitioners of this world lacked was not resources, but the strength to fight against demonic entities.

A few days later,

Lin Yuan successfully refined that demon spirit.

"It is almost enough to let me open more than three hundred particle worlds."

A smile appeared on Lin Yuan's face. A single demon spirit had such an effect; those great demons and even Source Demons? How great would their help be to Lin Yuan?

Of course, in the short term, Lin Yuan would only make a move against demon spirits and great demons. As for Source Demons? Even if he recovered to his full strength, Lin Yuan would not easily make a move against Source Demons.

According to the conclusions drawn by Lin Yuan from the many ancient books and records seen in the Qingyun Institute,

the so-called Source Demon was very likely related to the legendary Demon Gods in legends.

Rashly refining a Source Demon might summon the gaze of a Demon God.

If Lin Yuan's speculation was correct, the Demon Gods of this Origin World benchmarked against Thirteen Step Time Life.

Furthermore, judging by the performance of many demonic entities, the Demon Gods probably were not very smart either, and would not be like the Six Ancestors, who would view Lin Yuan's future timeline in advance and thus choose to befriend him.

"It's time to go back."

Lin Yuan immediately chose to return to the Qingyun Sacred Mountain.

The majestic energy obtained from the demon spirit he had just refined was enough for Lin Yuan to Cultivate for a period of time.

Just like that,

every once in a while, Lin Yuan would quietly leave the Qingyun Sacred Mountain and come to the outside world to hunt 'demons' to provide himself with the means to open particle worlds one by one.

Time passed quickly.

In the blink of an eye, a millennium later arrived.
