The first time I saw the boundary stone was when I was in the old town of East.

Each boundary stone contains a rich world origin, and it is generally a currency used for trading between the powers of the Holy Realm, but I didn't expect this thing to be used in the cosmic sea.

"The boundary stones are also divided into grades, low-grade, medium-grade, upper-grade, and superb, and the quality of the world's origin contained in them is the same, but the quantity is a hundred times different. ”

The Emperor of the Underworld took the initiative to popularize science.

"When you arrive in the Cosmic Sea, you can take some time to familiarize yourself, but it is said that the Lord of the Dao Sect is about to start a war with the Emperor of the Marauder camp, so don't run out for the time being. The Immortal Emperor reminded.

"That'...... What about the immortal matter?"

Qingxi asked.

"Don't worry, after this battle, we will take you to the Dao Sect and gather enough immortal matter that can allow you to break through the first step of the Half Emperor. ”

Tai Agu Di said.

Qingxi has always hidden his aura with the Void Devouring Celestial Body, and with the eyes of the four Immortal Emperor Realms, he can't see that he has broken through.

"Actually, I am already immortal in the flesh. ”

Qingxi raised his palm and released a thick immortal power.

The pupils of the four ancient emperors shrank suddenly.

"How is that possible?"

"Where did you get so much immortal substance?"

"Did you ransack a whole new universe?"

"This is a big sin in the Great Dao Alliance!"

The faces of Emperor Tai Agu and the others changed suddenly, and they all immediately showed worried expressions.

Within the Great Dao Alliance, cultivators are strictly forbidden to plunder the universe under their command, and once discovered, they will issue a cosmic sea hunt and kill order.

Normally, even a lone Immortal Emperor Realm would not be able to escape the pursuit of the Great Dao Alliance's All-Universe Sea.

Such cultivators are basically wiped out in the end.

If you are lucky enough to survive, you will basically join the Marauder camp and become the public enemy of the Dao Alliance and the Wanderer camp.

Therefore, the Immortal Emperor was very worried that Qingxi would take the wrong path.

It would be a pity if such a rebellious pride was wiped out or joined the camp of the marauders.

What's more, this Tianjiao is also the descendant of their great universe.

"Don't worry, seniors, I didn't do that. ”

Qingxi hurriedly waved his hand, "How could I plunder other universes, just by exchanging them for immortal substances and other cultivation resources. ”

When everyone heard this, they immediately breathed a sigh of relief.

As long as it's not plundering other universes, that's fine.

But soon, new doubts arose.

"To this day, the immortal matter in the major universes has been collected by the two major forces of the Great Dao Alliance and the Marauder Camp, and there is no excess immortal matter in the single universe for a long time. ”

Emperor Tai Agu said in surprise.

"Even if there is still an immortal substance, it would be very good to be able to become an ordinary half-emperor in the first step, your foundation is so strong, how can you gather so many immortal substances?"

The Immortal Emperor looked puzzled.

Qingxi pondered for a moment and said, "The Immortal Emperor forgot, the grinding disc you left in the Chaos Mist Courtyard?"

The Immortal Emperor was stunned for a moment, and said with a strange face: "You mean, you kidnapped my treasure?"

But that's not right!

That grinding disc could only grind out an impure acquired immortal liquid, and could not be further purified.

It is impossible to become immortal by relying on impure immortal matter. ”

The Immortal Emperor, the Human Emperor, and the Tai'a Ancient Emperor had also heard of this treasure of the Immortal Emperor, and they also thought it was incredible.

As an Immortal Emperor Realm, which one is not a stunningly talented person?

Such beings can create legendary world-class treasures, and process and refine ancient medicines, immortal medicines, divine medicines, holy medicines and other heaven and earth spiritual objects to obtain acquired immortal substances with a purity of more than 99.99%.

But even if you add countless more 9s to the end, it's still not pure.

As long as the purity is not 100 percent, it cannot be useful.

Under normal circumstances, completely pure immortal matter can only be created at the beginning of the universe.

"I guess you all know that I created the Microcosmic Sea, right?"

Qingxi suddenly asked the people present.

"So what?"

The Human Emperor's thick eyebrows furrowed slightly, "Although our divine sense is extremely strong, we can all involve the particle level, and we have also tried to purify it from the particle level, but in the end, we can't reach 100% purity. ”

"Well, I didn't say that I was purifying immortal matter at the particle level, in fact, I used other methods, although it is also related to particles, but it may be different from what you think. ”

Qingxi took a sip of enlightenment tea, looked at the people with confused faces, and said.

The emperors looked at each other.

Not at the particle level?

What is that?

Not only them, but even the Emperor Realm of the other forces in the Cosmic Sea all agreed that purifying the immortal matter from the particle level was the best way.

There are even several Immortal Emperor Realms who have been studying this method all their lives.

The purity of the immortal substance they extracted had reached countless decimal places, but it was still a little bit worse.

If there is a method of complete purification in the world, once it is announced, there is no need to worry about the lack of immortal substances.

At that time, it would be possible to mass-produce the super-first-class powerhouse of the third step of the Half Emperor.

But if you want to break through to the three-dimensional one, you have to rely on personal understanding.

After all, if you don't create your own Dao, no matter how much immortal matter you have, you can't break through.

"So, what the hell is the method?"

Emperor Tai'agu's face was full of curiosity, "Is it convenient to say?"

"This matter has to start with the microcosm. ”

Qingxi pondered for a long time, seemingly considering whether to tell the secret, but in fact thinking about how to make up a reason.

The reason why he was able to transform into a pure acquired immortal substance was because of the transformation function driven by the legendary world-class spiritual root.

During this time, he was already working on a low-profile version of this feature.

I am also thinking about whether to publish this method.

Before that, he had no such intentions.

But since he passed through the Xuanji Universe Group some time ago, he had guessed the general situation of the Cosmic Sea, and knew that the so-called immortal matter had long been depleted.

And his breakthrough can't be hidden after all.

Rather than being suspected when the time comes, think of a better way to deal with it.

For example, to create a viable method of purifying immortal matter.

As a "super demon" who can create the best way to seal the gods, Qingxi thinks about his own method of recreating and purifying, which should also be reasonable.

Moreover, he used good fortune and evil fortune to predict his own state, and found that if he really created the method of purification, it would be a "great luck" state.

If it weren't for this, he would have sneaked back to the great universe to escape the world long after he took the first step to become a half-emperor.

"The microcosm has something to do with the purification of immortal matter?"

The Immortal Emperor looked dazed, and tapped his fingers on the table, it was really difficult to understand why there was a connection between the two.

"Of course it is. ”

Qingxi nodded and said.

The Emperor of the Underworld could see that Qingxi deliberately didn't want to say it, so he changed his words and said, "It's okay not to say the specific method, but you can always show it, right?"

"Lend me a hundred thousand years old medicine. ”

Qingxi said.

"Ancient medicine that is more than 10,000 years old, I'll take it here!"

Emperor Tai'a Gu was rich and wealthy, and directly took out a high-level space ring, and the inner space was comparable to a small world, which was actually an ancient medicine garden.

Not to mention the 10,000-year-old ancient medicine, it is millions of years and tens of millions of years.
