Xuan Qing held it in his hand, it was heavy, and the book weighed two or three pounds. He flipped it open and read it carefully.

Yun Qingshui saw that he was in a trance, and did not bother, and then left the secret room.

In the secret room, only Xuan Qing was left. He was deeply attracted by those words, read the book thoroughly in one breath, and compared it with the Ding furnace, and then stopped. He took out more than 100 relevant volumes from the bookshelf and began to study them, and for three whole days, he forgot to sleep or eat.

I was sleepy and leaned on the scroll and squinted for a while, then got up and continued to read.

Xuanqing relied on his good mental strength and not bad physique, so he was bored for three days, and finally mastered the basic methods of filling.

When he walked out of Yun Qingshui's secret room, he was in a trance.

Xuan Qing held it strongly, and such a large-intensity battle consumed a huge amount of spiritual power.

He rubbed the corners of his aching eyes, and suddenly remembered that it was time for Da Wudan to open the furnace, so he immediately shook his body and came to the side of the giant ding.

The top cover had been untied by Dantong at this time, and Dantong was cleaning up the waste residue on the ground.

"What about Cheng Dan?" asked Xuan Qing.

"Not only did not make a single one, but this furnace was all wasted. That Dantong said secretly annoyedly.

In the pile of waste slag, Xuan Qing looked carefully, and in a very inconspicuous place, he picked up the big udan, which was a little uglier than the original, hidden in the charcoal fire and waste materials, very inconspicuous.

Xuan Qing leaned over and picked up the big udan and put it away.

"In the past, was the success rate also very low?"

Glancing at the scum on the ground, Xuan Qing asked lightly.

"In the past, there were at least fifty percent, and this furnace ...... It turned out to be nothing. ”

After the boy finished speaking, he turned and walked away.

Xuanqing held the pill, walked towards the bedroom, ate something simply, starved for three days and the body was in a state of emptiness, ate three plates of meat, and filled a bottle of wine to feel better.

He took out the burnt udan and looked at it carefully, but he couldn't see anything special, and when he tried to swallow it, he found that it was as hard as a stone.

Xuan Qing smiled bitterly: "It's wasted." ”

However, he did not lose heart, and after reading the books in the secret room, he realized that the main reason for the failure of the Great Udan was that he misplaced the direction.

The composition of the Great Udan corresponds to the position of the Bagua Qian, that is, the northwest direction. He misplaced it in the Kun location, which is southwest. It's no wonder Dan ruined. Knowing the reason, Xuan Qing took out a big udan again, this is the fourth.

He neatly poured the Great Udan into the spiritual spring water, and when it was time to wait, he came to the furnace, calculated the direction, and put it in again.

"You can't go wrong this time!"

Xuan Qing wrote down the brand number of the furnace ding, and then went to Yun Qingshui's secret room.

Ever since he decided to study alchemy, the Chamber of Secrets has become a place he frequents. He was so motivated, Yun Qingshui simply threw all the keys to the various organs to him, and now Xuanqing came to the secret room to read the books whenever he had enough time.

Alchemy requires a lot of knowledge from a person.

Xuanqing must read a lot of books, record all the knowledge in the books in his mind, and integrate it in the alchemy of reality, so that he can be called a qualified Danshi.

This stay was another three days and three nights.

The dozens of books on the shelves in the secret room had already been read by him.

Three days later, Xuan Qing came out of the secret room and rushed directly to the furnace.

This time he came a little early, the furnace had not yet been opened, standing next to the furnace, Xuan Qing's mind was a little worried.

I wonder what will happen this time?

I saw that the huge lid of the stove was slowly opened, and Dantong held the plate and stood on one side.

The heat in the furnace slammed out along with the ashes, Xuan Qing took two steps back, wiped the ash on his face, and looked into the furnace.

The little boy pressed a few times on the stove arm, and the pills were suspended one by one.

The little boy looked happy, took the plate in his hand, and those finger-sized pills fell down one by one. The tinkling sound on a child's plate sounds extremely crisp and pleasant.

After a while, the stove stopped moving.

Dantong, who was holding the plate, glanced at the furnace:

"Probably not...... This time it's good, it's fifty. ”

Just as he was about to close the small door on one side of the furnace, he saw a buzzing sound, and a small red Dan the size of a fingernail flew out.

The little Dan swayed and flew to the boy's plate.

The little boy picked up the little Dan in surprise, looked at it and asked, "What is this?" ”

When Xuan Qing saw Xiao Dan flying out, his heart suddenly rejoiced.

"Mine. ”

He raised his hand and took the little pill from the little boy's hand. Regarding the matter of the monk putting the pill in the furnace by himself, although it is expressly forbidden by the sect rules, and people outside the pill shop are definitely not okay, but Xuan Qing is wearing the clothes of the pill shop at the moment, and the little boy does not say anything.

Holding that little pill, Xuanqing couldn't help but be excited for a while.

This is a small red Dan, crystal clear, and the original big udan is simply two things. Xuan Qing gently stroked this little Dan, such a small thing, how much effort he put in!

Now, I've finally practiced it, but I don't know how effective it is, so I have to give it a try!

He held Xiao Dan in his hand, ran wildly into the pine forest, found a quiet place, and sat down cross-legged.

Throwing that little pill into his mouth, he felt that his throat slipped, and the dantian was hot for a while.

The red bead fell into the abdomen, and the white crystal nucleus in the body suddenly brightened, and it lasted for more than a dozen breaths before it slowly returned to this.

Xuanqing conditioned his body and slowly ran the meridians.

"Ugh. Breathing suddenly, Xuan Qing only felt that the meridians were subject to layers of resistance in the operation, and there were also bursts of pain that penetrated the bones.

After a while, the red bead quickly rotated in the body, and the speed became faster and faster, like a wind wheel that was speeding up, colliding uncontrollably in the dantian.

The original condensed true qi layer was scattered by it.

Xuan Qing gritted his teeth and tried his best to control Pingheng, and at the same time, completely ignoring the pain in his body, he ran the meridians strongly.

Titicaca.

Every breath you take is accompanied by bouts of pain. The pain spread from the limbs to the chest one by one, becoming stronger and stronger, more and more violent, the fluctuation and pain, and finally concentrated into a big explosion.

Xuan Qing's body shook and spurted out a mouthful of blood.

After a few more breaths, everything was calm.

The red beads in the body disappeared, and at this time, they had completely fused with the true qi in the body. The scattered true qi layer was re-placed, and Xuan Qing felt it carefully, and there were a lot more true qi layers than before.

When he opened his eyes, Xuanqing was overjoyed.

It's finally done!

This ugly Great Udan has smoothly turned waste into treasure in his hands! This effect is not inferior to that of the Great Ink Dan.

It's just that when I have my period, it hurts too much.

But he had to endure this pain, and who made him destitute and poorly aptituded! He could not find a second way except to work hard.

After practicing for another two hours, Xuan Qing stood up at this time.

There is a heavy sense of harvest in my heart, and now that the Great Udan test has been successful, I want to refine the remaining two pieces as soon as possible.

As soon as he said to do it, Xuanqing immediately found the remaining Da Wudan and placed it in it.

Three days later, it was time to take the pill again.

"Let's go, take Dan!"

Xuan Qing said to Xiao Wu, who was still asleep. Xiao Wu rolled on the bed, I heard that the master was going to take the pill, presumably there was a new progress in the recent experiment?

Xiao Wu didn't ask, he was used to the master giving surprises.

The two of them came to the alchemy room and found the furnace where the big udan was placed, and the little boy was collecting the pill.

When he saw two jujube-red Xiao Dan flying out, Xuan Qing raised his hand to catch it.

pinched one of them and showed it to Xiao Wu.

"This is what Da Wudan refined, I have tried it, and the effect should be no worse than that of Da Ink Pill. ”

Xuan Qing said lightly, "According to the description of the palm envoy, twenty big ink pills can help cultivate to an advanced level, and this little pill is not bad at all!"

Xiao Wu Yile gently pinched Xiao Dan in his hand, for fear that he would break it if he was not careful.

Xiao Wu gently stroked this little Dan:

"Baby, what a baby, master, did you name him?"

Xuan Qing smiled faintly: "Not yet." ”

He only experimented with the effects of this elixir, and where could he bother to name it.

Xiao Wu Ning Xiao Dan in his hand grinned: "It is refined by Da Wu Dan, and it is all vermilion, so it is called Da Zhu Dan!"

Xuan Qing nodded in agreement.

The two of them took the big Zhu Dan and walked back happily.

"Master, what's next?"

"Now I have a lot of spiritual spring water, but Da Wudan is not easy to find. "That Great Udan was already bought out by him last time in the Phantom Sound Palace, even if he waited until the Phantom Sound Point opened again, it was only one.

If you only have one per month, it is really not enough, and you have to find more of it.

"Leave it to me. ”

Xiao Wu has always been happy about this kind of thing of going to heaven and earth and inquiring about things.

In the following time, Xiao Wu inquired about the elders, new disciples, and previous generations of disciples through various methods.

In the past ten days, when Xuanqing woke up, he was always gone, and when he went to bed at night, Xiaowu still didn't come back.

After tossing like this for about ten days, on this day, Xiao Wu panted and returned to the dormitory with a cloth bag, and was out of breath when he entered the door.

Xuanqing was meditating, and when he saw Xiao Wu coming in, he said:

"You're back. ”

Catching up with the owner's worried gaze, Xiao Wu said, "I can find it...... It's all here. ”

As he spoke, he shook the cloth bag in his arms, and with a bang, a large number of big udan immediately rolled out of the cloth bag. Those big udans were stacked on top of each other, piled up into a small black mountain.

Xuan Qing was overjoyed: "So much!"

Although he never doubted Xiao Wu's ability, so many big Wu Dan were still beyond his expectations.

“...... Is it enough?" asked Xiao Wu, gasping and leaning against the edge of the table.

"Enough, enough!"

There are so many big udans, not to mention that they will be supported until the end of the year, and even next year's year will be enough.

Xuan Qing excitedly stroked those big udans, now with the udan, plus the spiritual spring water he originally had, he will show his strength in the future!
