Outside the hut, Bai Xiaowu put down the cup and walked to the lake, looking at the cold wind sitting in the middle of the lake with a scorched mouth.

With a low sigh, she crouched down, picked up small stones from the ground, and threw them into the lake, one by one.

Even though her expression was a little gloomy, her eyes were still bright.

Zou Lao told Bai Xiaowu a few months ago that he wanted to leave her, Bai Xiaowu was definitely unwilling at that time, and after Zou Lao's repeated persuasion, Bai Xiaowu could only agree. Now that she knows that this moment will come soon, she will inevitably feel a little depressed.

Although Bai Xiaowu also knew that Zou Lao was not her own grandfather, Bai Xiaowu, who had followed Zou Lao since he was a child, couldn't imagine that Zou Lao was not around. Despite all his reluctance, Bai Xiaowu didn't make a fuss for too long because of this matter.

"Maybe what Grandpa is going to do can really affect the entire immortal cultivation world. Bai Xiaowu muttered to himself, picked up a piece of firewood beside him, and rubbed the layer of stone and sand on the ground.

In the thatched hut, Zou Lao summoned a liquid shining with multicolored light from his own world, and the color of the liquid light kept changing, as if turning into a water snake, swinging in the air.

"It's the old man's medicine technique, and now it's yours. ”

Yue'er didn't understand what Zou Lao meant, but after he made a few seals on his hand, the inexplicable multicolored liquid suspended in the air suddenly flashed a light, and then converged.

Zou Lao's palm stretched out, and the multicolored liquid converged into a round ball, beating on Zou Lao's palm.

"This is formed by the elixir liquid, which records the medicine technique, it is not only a pharmaceutical secret book, but also a medicine that can live and die human flesh and bones. ”

Zou Lao's palm moved, and the elixir spheres suspended in his palm suddenly dispersed, tiled in the void and turned into many small round balls, and these small round balls quickly changed into different words, arranged in an orderly manner.

And these words are exactly what Zou Lao said about alchemy.

As Zou Lao pointed his finger at Yue'er's abdomen, these words composed of elixir liquid drilled into Yue'er's volume word by word, and fused again in Yue'er's volume to form a round ball.

Yue'er felt that this qiē was incredible, a medicine that can give birth to life and death, and it is also a pharmaceutical technique, which can change with Yue'er's mind, and the beating words float to her mind, which records how to make medicine.

"The materials used to refine this liquid are quite precious, and once part of it is used, the medicine technique will not be complete, so don't use it unless you have to. ”

Even if Zou Lao didn't say it, Yue'er also knew that she could feel that after this elixir liquid entered the volume, the breath of life continued to overflow from the medicinal liquid, and even if Yue'er was not meditating at the moment, she could feel that the aura around her was slowly entering her volume.

"You must let Leng Gongzi learn the magic of medicine, the elixir can enhance his physique, and thus also enhance the connection between the soul body and the physical body. ”

It turned out that Zou Lao handed over the pharmaceutical cheats made of this elixir to Yue'er, thinking about how Guò Yue'er came to tell Sù Leng Feng how to make medicine.

On the other side, the cold wind is still absorbing the aura on the lake, and for some reason, on this lake, there is no restlessness in the heart, and the aura is very abundant, once you sit down, you don't seem to want to get up.

In this way, a few days passed, and the cold wind still sat on the lake, motionless, as if petrified.

Yue'er took advantage of these days to learn how to make medicines, while Zou Lao taught on the side.

Different from alchemy, medicine is not about spiritual power, but about the combination of materials. Anything rich in life can become a pharmaceutical material. The more materials a medicine contains, the more complete it will be. The most important point of medicine is that it needs to consume the spiritual power in the body, and the spiritual power that needs to be consumed is not ordinary spiritual power.

The alchemy technique that Zou Lao conveyed to Yue'er explained how to convert his spiritual power into the spiritual power needed for medicine. This kind of spiritual power is cultivated according to the description of the pharmaceutical technique, and the spiritual power can independently fuse the desirable points of the pharmaceutical materials and refine them in the flame of the tongguò.

This kind of flame is the same as the flame used in alchemy, and the difference in flame can also directly affect the effect of the medicine.

Pharmaceuticals can be said to be an endless minor immortal art, there is no law at all, and the medicine that is refined is also different from person to person, and the formula also needs to be mined by pharmacists. The pharmaceutical knowledge that Zou Lao taught Yue'er was only to tell her how to transform the spiritual power in her body into the spiritual power needed for medicine, and the most important thing in medicine is to be able to transform the nature of the spiritual power in her body at will.

Before I knew it, a few more days had passed.

In the middle of the lake, where the cold wind was originally sitting, formed a blue insect-like aura membrane. If you look closely, you can see that this aura membrane is made of many blue aura filaments that quickly rotate around the cold wind.

I have to say that above this lake, it is an excellent place to cultivate, the cold wind has never absorbed the aura so quickly, and the aura here seems to be very pure, and it is completely possible to use some aura to make the zuò rune spirit.

In this way, the cold wind sits for a few days. On this day, when he opened his eyes, all the blue spiritual energy filaments that swirled around him drilled into his body, and he suddenly felt that the newly born Chiyang Sword in his soul body had materialized as much as half.

In just a few days, it has improved so fast, which makes Leng Feng shocked in his heart, and he really wants to stay on this lake and is reluctant to leave.

However, it is less than three months before Hengshan talks about it, and he needs to find his next opponent to improve his fighting experience.

So, Leng Feng stood up and walked towards the hut, and the water spread out in circles as he walked.

When I came to the front of the hut, I saw Yue'er squatting on the ground, holding her right hand with her left hand, and the two fingers of her right hand stretched out, emitting a spiritual power from the two fingers into a jar a few feet in front of her. There is a normal flame burning underneath the jar, and some dim gas is coming out of the jar from time to time.

Leng Feng stood beside Yue'er, although he didn't know what Yue'er was doing, he didn't ask, just asked lightly.

"What's next?"

Yue'er clenched her teeth and said as she injected spiritual power into the jar

"Do you want to go?" Yue'er plans to stay, Xi will be leaving. ”

The cold wind hesitated for a moment, turned into a golden light and flew into the sky, and disappeared from Yue'er's sight after a while.

Yue'er, who turned her head, smiled slightly, then let go of her hand and wiped the fragrant sweat from her forehead.

Looking at the medicine in the jar, it seemed that this time it had failed again, and the spiritual power in Yue'er's body was not enough to fuse these materials that were put in.

I didn't expect that refining ordinary medicine would require such a huge amount of spiritual power. At this moment, Yue'er only felt that there was not much spiritual power left in the instrument, and if he didn't use his luck to restore it, I am afraid it would dry up.

So she sat down on the spot and began to adjust.

After a while, Zou Lao walked over and said

"Is he gone?"

Yue'er didn't open her eyes and said

"He doesn't know the way. ”

Zou Lao kept looking at the direction where the cold wind disappeared, and he felt that the breath belonging to the cold wind was flying back.

"He's back. ”

After a while, I saw a golden light flash in the sky, falling between Yue'er and Zou Lao.

The cold wind after landing just said lightly

"I don't know the way. ”

Then he walked towards the lake
