The sky was dark, and a touch of chaos rose in the east.

On the night road, a figure galloped by, heading towards Qingshan Town.

"Dan Ling, can the elixir in the mustard seed ring be able to refine the Xuandan?"

"Yes, of course!

Dan Ling is now temporarily residing in the mustard seed ring, counting all kinds of heavenly and earthly treasures for Yun Mu. Hearing Yun Mu's inquiry, Dan Ling immediately gave an affirmative answer, and his tone of voice was excited.

In fact, Dan Ling is naturally very fond of heaven and earth treasures, and it has not been in contact with it for tens of thousands of years.

In contrast, although Yun Mu was equally happy, he didn't care too much, after all, he hadn't experienced the difficulties of alchemy, and he didn't know the preciousness of these heavenly and earthly treasures.

"Dan Ling, do you have any elixirs there that can improve your cultivation?"

"Yes, yes, but your cultivation has improved very quickly, if you use the pill to forcibly break through the realm of Xuanzong, I am afraid that it will damage the foundation and be detrimental to your future cultivation. ”

Dan Ling persuaded Yun Mu very responsibly, although it admired Jindan Avenue very much, but there were gains and losses...... When a practitioner wants to gain strength faster and easier, he is destined to lose his solid foundation.

Heaven and earth are natural and operate in balance, which is also the truth of the world.

"You think too much, refining the pill is not for my own use, but for others. ”

Yun Mu shook his head directly, and said in a deep tone: "I always feel that this Mountain Gate Ceremony will definitely not be calm, so you need to make some preparations, you will refine the pill to see if there is a suitable pill that can break through the shackles of the realm and directly improve your cultivation, it is best not to have any side effects." ”

Although Yun Mu didn't know how to refine the pill, he also knew that some pills could not be eaten indiscriminately, otherwise the consequences would be unimaginable.

"Well, I'll take a look at it...... Ascend to ......"

After a moment of silence, Dan Ling suddenly shouted, "There is......! That's right! It's the Little Spirit Barrier Breaking Pill! The Ancient Dan Dao is broad and profound, although the grade of this Little Spirit Barrier Breaking Pill is not high, but the effect is extraordinary, once the cultivator takes it, it can stimulate the potential of the body, slightly improve personal cultivation, and it just so happens that the elixirs here are very complete, and it should be able to refine a few furnaces. ”

"Is this Little Spirit Barrier Breaking Pill useful to Xuanzong?"

"Xuanzong, what ...... this?"

Dan Ling didn't expect Yun Mu to refine the pill for Xuanzong, so he thought about it seriously and said: "It should be possible! Today's Xuanzong is far inferior to the martial arts masters of the ancient period, this pill is useful for the ancient powerhouses, and there should be no problem for Xuanzong." ”

After a pause, Dan Ling continued: "In addition, the side effects of the Xiao Ling Barrier Breaking Pill are very small, there is no residual erysipelas, and it only takes three or five days of meditation to refine the spirit pill and consolidate the realm, and it will not affect its own foundation. The only thing to note is that this pill is very strong and will cause a certain impact on the body, you can only take one pill at a time, and the time and limit of each dose are determined according to your personal physique...... In short, alchemy is very complicated, and it is necessary to pay attention to the use of alchemy. ”

Yun Mu nodded, and couldn't help but breathe a sigh of relief in his heart: "Okay, then the matter of alchemy will be handed over to you, I hope you can refine it as soon as possible." ”

"No problem guaranteed!"

Dan Ling took a big bag, patted his chest and said: "With so many medicinal materials, I can see that your heart is itchy, I have long wanted to try it! What's more, you take the two poles of fire and the mystery is infinite, and it is in line with the meaning of the Great Dao, I also want to see its power." ”

To be honest, he has been living in Danding since the day Dan Ling was born, although he has witnessed the birth of many pills, he has not really practiced it personally, so he is now more anxious than Yun Mu to show his ability, he wants to prove his worth.

......

Half an hour later, a person and a spirit entered Qingshan Town.

At this time, it is still dark, but the town is bustling with activity. Many powerful people gathered here, and under the guidance of the outer disciples, they all headed towards the mountains outside the mountain.

Yun Mu did not delay, and ran directly to the town medical hall, where Dr. Mu had been waiting for a long time again.

"Congratulations to Yun Xiaoyou, who has returned safely. ”

"Dr. Cheng Mu Ji Yan, although there were some twists and turns in this trip, but it was relatively smooth. ”

While greeting Yun Mu, Dr. Mu was supported by his subordinates and walked into the inner hall.

As for what happened in the Outer Heavens, Dr. Mu had already found out through his own channels. Tianzhao vision, the relict realm suddenly changed, he thought that Yun Mu would not be able to come back, but he didn't expect to stand in front of him now.

After the two sat down, Dr. Mu waved away, and only him and Yun Mu were left in the inner hall.

"Cloud Little Friends ......"

Dr. Mu looked excited, with anticipation on his face and a little apprehensive.

Yun Mu knew what the other party wanted to ask, so he didn't go around in circles, and directly took out a scroll from the mustard wheel and handed it over.

"Doctor Mu, this is what you want, please take a look. ”

Hearing what Yun Mu said, Dr. Mu's body trembled slightly, took the scroll with trembling hands, opened his mouth, and couldn't say a word for a long time.

Some people, although they were born ordinary, have a supreme mission, and they have passed on the torch from generation to generation, continuing the civilization of the human race.

Dr. Mu was such an ordinary person, and on the first day he became a healer, his master told him to pass on his medical skills. So he never gave up his responsibility to find the Thousand Machine Scrolls.

In fact, not only Dr. Mu, but also many thousands of disciples in this world.

"Heavenly Eye Technique, open!"

Doctor Mu's mind condensed, and his eyes burst into two intense rays of light.

Seeing such a scene, Yun Mu had a hint of enlightenment in his heart...... It turned out that Dr. Mu opened the spiritual aperture of the eyes, so although the eyes were blind, he was able to see the things around him clearly through the eyes of the mysterious spirits.

"Sure enough...... Sure enough, it's a thousand machine rolls!"

Dr. Mu touched the scroll, and the whole person was excited. However, when he opened the scroll and looked at it, a deep look of disappointment appeared on his face. The scroll does not record the art of medicine, but the method of making various mechanical instruments.

"It's a pity...... It's a pity......"

Doctor Mu muttered to himself, and the gap in his heart made him extremely decadent. Ten years of waiting, only to be exchanged for a volume of useless things...... No, it shouldn't be said to be useless, it's just useless to healers.

"What? This thing is not what the predecessors wanted, but it is the only thing in the Asker Pavilion. ”

Hearing Yun Mu's words, Doctor Mu shook his head bitterly and said, "No, I want to get this thing, but unfortunately, the content recorded here is far from what the old man wanted...... The old man is a descendant of a medical family, and the things recorded on this thousand machine scrolls are the content of Tiangong. ”

Hearing this, Yun Mu was silent, he could very well understand Dr. Mu's mood at the moment. Ten years of waiting, a fantasy, no one's heart will feel good.
