The mist entered the body with the breath, turning into a stream of pure energy, and with the twenty snow dragon phantom inner elements running in the limbs and hundreds of remains, every time it ran a big week, it would be transformed into Ye Qingyu's inner element power, and finally like a hundred rivers returning to the sea, it would enter the dantian desert world.

This kind of internal element growth rate far exceeded the effect of any of Ye Qingyu's previous cultivations.

Breathing and breathing, the element is increasing every minute and every second.

Yuan Jing slowly floated, levitating half a meter in front of his face.

Countless silver mist that was as fine and dense as an octopus's tentacles continued to separate from the source crystal, and with Ye Qingyu's breathing, it entered his body, and the speed of the entire source crystal was also visible to the naked eye, and it was constantly shrinking, as if it was a piece of ice contained under the scorching sun, melting bit by bit.

Less than a stick of incense later.

Rumble!

An invisible power fluctuation came out of Ye Qingyu's body.

The twenty-first snow dragon phantom slowly appeared around Ye Qingyu's body.

A faint dragon groan came out.

Twenty-one eyes of the spiritual spring.

When the twenty-first snow dragon phantom first appeared, it was still a little illusory and dim, but with Ye Qingyu's breathing, as the power of the source crystal continued to enter the body, soon this snow dragon became full and moist, and the actions became more and more flexible and elegant, as if it had gained life, and began to exude a faint coercion.

After another stick of incense.

The twenty-second Snow Dragon Phantom appeared.

Another incense stick time.

Twenty-third ......

Another hour later.

The snow dragon phantom that was haunting Ye Qingyu's side had increased to twenty-five.

Each snow dragon phantom is like a real dragon, meandering and flying and circling, guarding Ye Qingyu in it, shuttling in and out from his mouth, nose, facial features, navel and eyes, running around the sky, the speed is like a streamer, and when it reaches the extreme, it completely turns into a silver halo with the power of a real dragon, guarding Ye Qingyu in it.

At this time, a faint flush appeared on Ye Qingyu's face.

And the piece of source crystal suspended in front of him was less than a quarter of its original size.

Slowly exhaling a breath of turbidity, Ye Qingyu stopped running his mind and opened his eyes.

Yuan Jing fell into the palm of his hand.

Ye Qingyu was thoughtful.

"It is worthy of being the exclusive product of the cultivation of the powerhouses of the Bitter Sea Realm, such a small piece of source crystal actually contains such a majestic power, just three hours, let me open the eyes of the five spiritual springs in a row, it is worth the past few months of hard cultivation, you must know that my normal cultivation speed is already extremely fast, if it is an ordinary martial artist, this small piece of source crystal is enough for them to save a year or two of cultivation time." ”

To be honest, with such a cultivation growth rate, even Ye Qingyu felt a little shocked.

Since he practiced martial arts, his biggest opportunity to increase his strength by leaps and bounds was when he was caught by Chen Moyun, the king of Qingluan Dan, and stuffed into the Yunding copper furnace, wanting to refine Ye Qingyu into a human pill, but he absorbed the Baicao Divine Liquid and a small piece of source crystal, achieved a big breakthrough in strength, and finally killed Chen Moyun.

And this piece of source crystal just now was about twice as large as the one that Chen Moyun sacrificed into the Yunding Copper Furnace that day.

"However, although this source crystal is good, it can't be absorbed unlimitedly, my ** strength, among the martial artists of the same realm, is definitely the first, but after absorbing the power of the source crystal for three hours in a row, in the meridians and acupoints, I have already felt the swelling and unbearable, obviously because the increase in strength is beyond the **normal tolerance limit, so I need to slowly adapt to it, and then absorb it for the second time!"

Ye Qingyu realized in his heart.

The reason why he stopped cultivating just now was because the power of the source crystal continued to enter the body, and after opening up the twenty-fifth Yuan Qi Spiritual Spring, the body of the limbs and meridians felt a feeling of swelling, just like a person would have a stomachache after eating too much, if he continued to cultivate, he was afraid that it would damage the meridian body, but it would not be beautiful.

"Yuan Jing is worthy of being the crystallization of the aura of heaven and earth, and it can be favored and competed for by the powerhouses of the Bitter Sea Realm, it is really a good baby. ”

Ye Qingyu was very satisfied with the results of tonight's cultivation.

After storing the remaining small piece of source crystal into the Yunding Copper Furnace and preserving it, Ye Qingyu was a little worried.

"If there is enough source crystal support, I can definitely enter the Bitter Sea Realm within two or three years and become a top powerhouse, and at that time, I will have more room and strength to help protect Xiaojun, and I can also find a way to go to the Snow Country Royal Priest Temple as soon as possible to solve the mystery left by my father before his death. ”

Ye Qingyu was looking forward to it.

But the problem is that the treasures in the source crystal are too rare.

Even for the entire Snow Country, it is a strategic-level national resource, and the source crystal mineral deposits in the Snow Country have been divided by the major powers, most of which belong to the empire, and only the imperial family has the right to mine, Ye Qingyu was named a marquis, and he got such a small piece for the first time, even if it is a big man like Lu Chaoge, the god of war of Youyan, it is impossible to get an unlimited supply, let alone Ye Qingyu himself.

What to do?

Ye Qingyu, who had tasted the sweetness of Yuanjing's cultivation, was a little bit of a marrow eater.

But after thinking about it, there seems to be no way for him to get enough source crystals.

If you can't get the source crystal, shouldn't you consider its replacement, if there is something, it can replace the cultivation effect of the source crystal, even if the effect is slightly worse, it's okay......

Wait a minute?

Substitute?

Ye Qingyu's eyes suddenly lit up, and he remembered the Danfang left by the old doctor Li Shizhen.

The content of the Dan Fang had been firmly engraved in Ye Qingyu's mind, and the content of this Dan Fang was not used to refine an elixir that could help a martial artist increase his inner element?

Damn it.

After coming to Youyan Pass for such a long time, because he was busy with all kinds of trivial matters, it was almost non-stop, and Ye Qingyu actually forgot about this matter.

He carefully recalled the contents of the Danfang.

"The text of this Danfang is undoubtedly from the ancient gods and demons, and the names of these raw materials recorded above seem to be heard of, and some are unheard of......" Ye Qingyu thought carefully, although he had read and paid attention to common knowledge such as alchemy before, but compared with the real Dan Master, it was too far and too far, and it could only be regarded as a half-understood understanding.

But this could not stop Ye Qingyu from being determined to refine the pill.

It is better to rely on heaven and earth and people than on yourself.

Ye Qingyu thought about it, and then took out the Dan Sutra found from Liu Yuanchang's corpse from the Yunding Copper Furnace, with the annotations of Chen Moyun, the Qingluan Dan King, which was definitely a Dan Dao classic that many ordinary Dan masters dreamed of.

Turning the title page of the Dan Sutra, a line of cinnabar characters jumped on it, saying

"There are three ways of Dan, one of which is medicine, the second is spirit, and the third is the avenue. Medicine, the basic of the Dan, all the Dan must have medicinal properties, with this nature, can be regarded as the one hundred and one of the Dan, but this is the Yongdan, taking it can dispel the harm of a hundred viruses, and take away the creation of plants and trees; the spirit, the spirit of the Dan, the Dan has the spirit, it is the Changdan, take it, it has a wonderful use, the wonder is endless, it can take away the creation of the soul; and the avenue is included, it is the supreme Dan, the creation of heaven and earth, up to the nine heavens of the sky, down to the Yellow Spring, the wonder is not in the grass and trees, not in the gods, but in the creation of heaven and earth, in the operation of the avenue, between the sun and the moon, in the stars, eternal and immortal!"

This is the opening outline of the Dan Sutra.

Ye Qingyu pondered carefully and comprehended the meaning.

That is to say, according to the rank of the division, Dan can be divided into three kinds: medicine pill, spirit pill and Dao Dan, medicine pill to cure diseases, spirit pill to cure life, Dao Dan is the embodiment of the order and law of heaven and earth, wonderful and infinite, containing heaven and earth.

He continued to flip through.

What follows is a very detailed elaboration of various pill theories, starting from the most basic medicinal properties, which is the so-called pill chapter.

The first level of the medicinal pill chapter is to read through the compendium of plants and trees, memorize the cold and heat properties and pharmacological effects of various spiritual herbs and elixirs, sprinkle tens of thousands of words, with brief illustrations, including Chen Moyun's annotations, which can be regarded as clear and understandable.

Ye Qingyu could only remember it, and after watching it once or twice, he had already firmly remembered it.

At the end of the medicine pill chapter, there is a reflection of Chen Moyun's annotation, and the content is varied.

But the general meaning is that he has painstakingly studied the Dan Sutra for countless years, thinking that he has a deep immersion in the way of alchemy, and his alchemy attainments are enough to rank among the top three in the entire Qingluan Province, but he can only be proficient in refining the Dan, and several attempts have taken countless efforts, and he can only refine half a semi-finished elixir, which is still a coincidence, and then he reflected, even he himself can no longer find a clue, as for the legendary Dao Dan, he dare not think about it.

"It turns out that Chen Moyun can only refine the pill ......"

Ye Qingyu was slightly surprised in his heart, and he had a better understanding of the division of the rank of the elixir.

He flipped back.

The next Lingdan and Dao Dan chapters, the content is extremely simple, just a rough explanation of what is the elixir, what is the Dao Dan, almost the general outline of the beginning of the Dan Sutra is re-elaborated, and about a list of several legendary elixir and Dan Dao names, but also just a scaly claw, there is no value of deeds.

Ye Qingyu was slightly disappointed, but felt that this was in line with common sense.

If this piece of Dan Sutra can be clearly expounded on the mysteries of refining the spirit pill and the Dao Dan like expounding the medicine pill, then the Dan attainments of Chen Moyun, the king of Qingluan Dan, I am afraid that he will not only stop at refining the pill, but he will not trade such an important book with Liu Yuanchang.

"I just don't know, the pill that Mr. Li Shizhen gave me is the pill of the medicine pill or the pill of the spirit pill?"

Ye Qingyu smiled.

He carefully read the Dan Sutra three or four times in a row, and after confirming that the contents of it were firmly in his heart, he thought about it, put his hands together, and a cold ice power poured out, completely icing this Dan Sutra, and then rubbing his palm, the Dan Sutra turned into a fine powder, floating between heaven and earth.

This Dan Sutra, after all, is Chen Moyun's thing.

I believe that at this time, Chen Moyun's death has become a mystery, Qingluan Academy will hunt down Chen Moyun's whereabouts, once it is discovered, he has this Dan Sutra on his body, I am afraid that it will cause a lot of unnecessary trouble.

After taking care of everything, through the window, the sky in the distance has already revealed the whiteness of the fish's belly.

The night passed.

Ye Qingyu got up, slowly stretched his waist, yawned, and was about to lie down to rest, when at this moment, the palm of his right palm suddenly burned and stabbed violently.
