Xu Yuan had already left, but the old man in the house, who was called yuanzun by Xu Yuan, turned his attention to the book in his hand and seemed to forget the existence of Chen Yu and Mu su.

Mu Su stood at the door, also silent, the atmosphere inside the house seems silent.

"Again!" Chen Yu curled his lips. After waiting for a moment, Chen Yu's heart was full of indignation. He simply walked around with his hands down, regardless of the old man.

The furnishings in the house can be described as very simple, not like the place where the head of the first courtyard lived, but Chen Yu's eyesight was not bad, and he still saw a lot of good things when he looked at them.

For example, there is a painting hanging on the wall, which is extremely exquisite. It also contains some mysterious artistic conception, which makes people feel ethereal after looking at it more.

There is also a red stove on a square table. The style of the red stove is primitive and full of ancient and mysterious runes. Chen Yu looks around and reaches out his hand to rub it. He can't help but tut tut.

Of course, Chen Yu had seen the Danlu, but he had never manipulated it himself. In the memory of emperor Xueyan, he had several experiences of alchemy, but his attainments were not very high. There was nothing left or right. Chen Yu studied the red stove carefully with his memory.

Although his attainments are not high, Chen Yu can also see that this Dan furnace is not an ordinary thing. The runes all over the furnace, especially the internal runes, are mysterious. What Chen Yu can see is that there are different kinds of runes that gather, disperse, circulate and defend.

Looking at Chen Yu's performance, Mu Su's eyes were a little dull.

This is the place of Daohong, the leader of Yaoling Academy. Daohong's position in Langya Jianzong is highly respected. The leader Zuo Xingzhou had to treat him with courtesy when he saw him. However, when Chen Yu came here, he was just like those shops in the secular world, which made Mu Su feel embarrassed for Chen Yu.

"Cough..." A light cough rang out, but Dao Hong finally put down the book and straightened up from the rattan chair.

His face was unsophisticated and his eyes were turbid. Like an old man in the twilight, he looked at Chen Yu in this way, but Chen Yu had a feeling of being seen through and knowing all the secrets.

This kind of feeling seems familiar. Chen Yu had a similar feeling when he met the old man who guarded the entrance of the secret place after he came out of the magic secret place of yulingzong.

Is the master of Yaoling academy a super strong man in the divine realm? This kind of feeling makes Chen Yu very uncomfortable. He jumps in his heart and turns around an idea.

"Get out!" Without waiting for Chen Yu to think more, Dao Hong suddenly gave a low drink.

Chen Yu gave a pause.

Dao Hong pointed to the door and said, "get out!"

Chen Yu could not help scratching his head and asked, "out? Where are you going? "

"Dou Qing!" Dao Hong's face was expressionless and he gave a low drink.

The young man quickly appeared at the door and said in a respectful voice, "master?"

"Give each of them a medicine bowl and a portion of Jingang powder!" Dao Hong lay down again, Dao.

"All right!" Dou Qing nodded, turned and disappeared at the door.

King Kong powder? Chen Yu didn't know why, so he looked at Mu Su, who was also at a loss, but still went to the door.

However, after thinking about it carefully, Chen Yu turned around and walked out of the door, muttering: "make a mystery!"

Dao Hong completely ignored Chen Yu's mumbling, took the book and continued to read it.

After waiting in the yard for less than a minute, Dou Qing came out of a room beside him, holding a medicine bowl in his hand and handing it to Chen Yu and Mu Su respectively.

The medicine bowl was very big, but it was rather heavy. Chen Yu took the medicine bowl and said, "what do you mean, elder martial brother? We're not here to make medicine!"

Dou Qing grinned and said, "I don't know. I just follow the master's arrangement! "

With that, Dou Qing picked up his own medicine bowl and pounded it up. The sound of pounding medicine was still rhythmic.

Chen Yu put the medicine bowl aside and couldn't understand Daohong's intention.

According to Chen Yu's conjecture, he was brought to yaolingyuan to contact the suspected warrior in yaolingyuan, but now this behavior of being asked to stamp medicine completely overturns Chen Yu's conjecture.

Dudu, Chen Yu is still pondering, and there is another sound of pounding medicine around him.

Chen Yu turned his head and saw Mu Su with a bowl in his hand and a pestle in his hand.

Compared with Dou Qing's pounding sound with a strong sense of rhythm, Mu Su's pounding sound is as sharp as silk, sometimes light and sometimes heavy. However, Dou Qing's sound of pounding medicine was not disturbed, and the rhythm was still clear.

Looking at Mu Su for a long time, Mu Su didn't speak to Chen Yu. Chen Yu couldn't help laughing bitterly. Then he carefully looked at the medicine bowl in his hand, and saw that there were several kinds of herbs in the medicine bowl, among which there were moist things like sand and stone.

"Well, it's just mashing medicine? I'll see what it's like! " With a murmur, Chen Yu rammed the pestle into the bowl with his right hand.

There was a dull sense of impact on his hand. The sound of pounding was like the tearing of cloth, just like the sound of musu.

"Well?" Chen Yu raised his eyebrows, controlled the strength of his hand, and continued to pound it a few times. The sound was like the collision of sand and stone. He couldn't make the sound of Dou Qing at all."That's interesting!" Chen Yu picked up the pestle and looked into the bowl for a while. He saw that the fresh herbs inside had been smashed and the slurry overflowed, but the gravel like things were still intact.

Chen Yu's heart moved, a vigorous Qi poured into his palm, wrapped the whole pestle, and then pounded it hard.

When This time, there was a sound like the impact of gold and stone, but the sand and stone in the medicine bowl were still intact.

Oddly enough, the medicine bowl, which looked like wood, was also intact. It was not smashed by Chen Yu This shows that the material of this medicine bowl is extraordinary.

"Emery is the hardest spirit sand. If you want to grind it, you should not only use Linggang, but also control your mind!" Dou Qing's voice suddenly rang out, saying: "if you can pound out a Jingang powder, it will be good for your Linggang control and the tempering of God's will!"

Chen Yu Chao Dou Qing saw that the latter didn't turn his head, but still pounded the pestle slowly.

But it's still very obvious.

"Lingsha? Is it the same refining material as the star sand? " Chen Yu asked.

"Yes, it's very common for Lingsha to be used as medicine!" Dou Qing still didn't turn his head and replied: "emery is hard and powerful. It is made of green root grass, aconite, rainbow shell powder and bawangzhi. Applying it on the surface of human skin for three days can make the skin as indestructible as emery!"

Unexpectedly, a Jingang powder had such an effect. Chen Yu only felt that it was an eye opener.

Compared with Langya Jianzong yaolingyuan, Chen Yu's superficial ability of distinguishing medicine and refining pills from emperor Xueyan was obviously far from enough.

"How long have you been making medicine, elder martial brother Dou?" Chen Yu's heart moved and asked.

"Since childhood!" Dou Qing replied.

Chen Yu can't help but look at Dou Qing more. From this simple answer, we can know that Dou Qing has been in Yaoling hospital since childhood, and should have been accepted as a disciple by Daohong very early.

"Now how long will it take you to make a diamond powder?" Chen Yu continued.

"Half a year!" Dou Qing is still not in a hurry to pound the medicine, but the answer is very natural.

Chen Yu was surprised.

Dou Qing, who has been practicing medicine since he was a child, takes half a year to produce a piece of Jingang powder. We can see how difficult it is to make it.

"It seems that Dao Hong is deliberately trying to embarrass me?" Chen Yu turned his mind and found it difficult to understand. It's the first time that he and Daohong meet. How can they be embarrassed?

After a while, Chen Yu shook his head, took the pestle and pounded it wholeheartedly.

Since Dou Qing, a disciple of Daohong's family, was able to concentrate on making medicine and regarded making "Jingang powder" as a kind of practice, Chen Yu had nothing else to do, so he didn't mind to experience it.

Dudu, pengpeng The sound of three pounding medicine is different.

At the beginning, Chen Yu found it difficult to concentrate. Every time the pestle fell and made a harsh sound, his attention was attracted by the impact sound, so that he was gradually annoyed by the harsh sound of emery friction.

The annoyance continued, and Chen Yu's thoughts began to be confused.

Realizing that he was influenced by the harsh voice, Chen Yu simply closed his eyes and no longer focused all his attention on the medicine bowl.

As a result, Chen Yu's mind became distracted, and all kinds of thoughts and ideas poured in, so that his sound of pounding medicine became weak and intermittent.

As time went by, Chen Yu focused on the medicine bowl again, staring at the emery in the bowl, and began to control the aura in the changing body, and the strength and location of the medicine pestle.

The reappearance of annoyance and aversion made Chen Yu feel anxious.

It seems that the most simple mashing is far from as simple as you think.

Chen Yu did not stop the action of pounding medicine, continued to change, and finally found the best strength and landing point at a certain moment, making the sound of pounding medicine no longer so harsh.

Chen Yu felt a little less annoyed and evil, and subconsciously closed his eyes.

In every sound of pounding, there is a little more charm.

Chen Yu suddenly found that as long as his mind is calm, as long as he doesn't force to smash emery, the process of mashing medicine is not particularly difficult.

With the passage of time, in the repeated sound of pounding medicine, Chen Yu felt that his mind gradually tended to be quiet, and no more thoughts appeared.

I don't know how long it took, but at a certain moment, Chen Yu suddenly found that his consciousness had entered the space of knowing the sea.

In the sea of knowledge, the starlight is pure and clear. Chen Yu "sees" another person holding a pestle under the stars and repeating the action of pounding medicine.

However, in the sea of knowledge, there is no sound of pounding medicine, but every time the pestle falls, the starlight begins to flow, like a fog, and the whole is shrinking.

All of a sudden, Chen Yu saw that in another starlight around him, there were five colors of spiritual light converging into the starlight, which kept fluctuating. The five colors of gold, wood, water, fire and earth rose and fell like tides, forming a close cycle.

Looking at this scene, Chen Yu's mind was empty, but he didn't have any superfluous ideas. He didn't think there was anything strange about this scene.Until the medicine bowl, suddenly appeared a red as blood.

At this moment, Chen Yu felt a strong spiritual fluctuation, and then he suddenly woke up, and the other self and the whole space of the sea disappeared together.

Chen Yu suddenly opened his eyes!
