Look at the smug look in the teacher's eyes.

Ye Mo nodded, and a trace of heat flashed in the depths of his eyes, as long as his immortal spirit continued to devour fire energy, sooner or later it would grow up, and then he would definitely be able to devour a spiritual fire and cultivate it into a flame that could refine the spirit pill.

Ye Mo shook his head, put the coveting of the spiritual fire in the bottom of his heart, and pulled his mind down to reality.

Seeing that Ye Mo came back to his senses, Mu Lao smiled slightly, and the dark purple flames in his palm kept surging, and clusters of flame vines were in the air, and they immediately dissipated.

"This is the Spirit Swallowing Grass, a fourth-level spiritual material, it looks no different from ordinary Spirit Grass, but this grass is extremely fond of absorbing spiritual energy, so its body is covered with pure energy, and the more blue light it emits on its body, the more pure energy it contains. ”

Grabbing a Spirit Devouring Grass in his palm, the old man explained to Ye Mo, and then gently threw it into the flames in his palm.

As soon as the Spirit Devouring Grass was touched by the "Purple Flame Soul Fire", it was calcined into a dark cyan liquid in an instant, and the liquid slowly rolled in the flames, reflecting a faint luster.

The purple flames were churning more and more intensely, but Ye Mo on the side was a strange discovery, the air outside the purple flames was getting hotter and hotter, but the feeling of making people's souls was getting colder and colder.

Mu Lao was engrossed in controlling the temperature of the flame in his palm, at this moment, as long as the temperature of the flame was slightly wrong, this dark cyan liquid would be calcined into a cloud of void air.

After the temperature of the flame was maintained to a certain limit, the dark cyan liquid suddenly appeared a little black impurity.

Looking at the black impurities that appeared in the liquid, Mu Lao nodded slightly, and with a flick of his fingers, a small ball of liquid wrapped in the black mongrel was expelled from the main body by him.

After expelling this black impurity, some small pale red impurities appeared one after another, and these impurities were all cleaned up by Mu Lao without exception.

In the continuous calcination of the purple flames, the dark cyan liquid, which was originally half a fist in size, had shrunk to the size of a thumb.

The clear cyan liquid slowly rolled in the purple flames, and the faint cyan was like a flowing cyan jade, faint and brilliant.

After calcining the first Spirit Devouring Grass to the size of his thumb, Mu Lao stopped calcination and put the other five Spirit Devouring Grass into it again, refining them all into five pure liquids as green as jade.

After a long period of calcination of the "Purple Flame Soul Fire", the six small liquids gradually fused, and after the fusion, the volume expanded a lot, but this phenomenon only lasted for a moment, and then shrank back to the original size.

After rolling in the flames for a long time, even within the cyan liquid, it seemed that a cluster of purple flames could be seen dancing.

Seeing this scene, Mu Lao quickly grabbed another spiritual material on the table with his palm, and then threw it into the flames.

"This is the four-grade spirit fruit rhyme spirit fruit. Mu Lao separated a trace of his mind and explained softly with Ye Mo.

As soon as the Yun Ling Fruit entered the flames, it turned into a cloud of turquoise liquid with a trace of aura, quickly removing the impurities in this turquoise liquid, and Elder Mu slowly covered it with a cyan liquid that was burning all over his body.

"Squeak..."

The two liquids with different properties collided, and suddenly there was a strange sound, and a faint white gas rose from the flames.

The white qi gradually weakened, and a rudimentary elixir with a rough surface quietly appeared in the flames.

Looking at the spirit pill that had taken shape calmly, Mu Lao nodded slightly, and once again put the spirit frost leaf and a fourth-order spirit core into it.

Forging into liquids, removing impurities, fusing with each other... Several tedious and delicate steps, Mu Lao almost did it in one go, without the slightest stagnation.

Seeing Mu Lao's neat movements, Ye Mo, a little white spirit refiner who only knew how to follow the steps and refine a first-grade spirit pill, couldn't help but sigh in his heart, so skilled and elegant movements.

After several spiritual materials neutralized the violent energy in the spirit core, a pill that looked round and smooth appeared in the flames, and after completing these steps, Mu Lao did not stop immediately, but kept the spirit pill in the flames for nearly ten minutes, and the purple flame in the palm of his hand slowly extinguished.

When the flames disappeared, Mu Lao slammed his left hand over a crystal bottle on the table, and then put the cyan elixir into it.

"Whew..."With a long sigh of relief, Mu Lao casually threw the crystal bottle to Ye Mo, and said lightly: "Take a look." ”

Carefully took the crystal bottle thrown by Mu Lao, Ye Mo took out the elixir, looked at the cyan elixir in his hand, and a familiar incense emanated from the elixir, making Ye Mo's aura move.

"This is a four-grade spirit pill and a green spirit pill, absorbing and refining can increase the spiritual energy in the body extremely high, and it is a spirit pill that many spirit king-level spirits are excited about. Don't you really want to improve your realm quickly? This kind of gentle Qingling Pill that will not damage the spiritual veins in your body is the most suitable, put it away, it can be regarded as a meeting gift for your teacher. ”

Ye Mo held the cool crystal bottle tightly, exhaled slowly, and said heavily: "Thank you, teacher." ”

"As for the higher-grade spirit pills, I can't refine them for the time being for some reasons, if you want to quickly improve your realm, you still need to learn the method of refining spirits by yourself. ”

"From today onwards, I will teach you how to identify spiritual materials. Mu Lao looked at the young man in front of him and slowly spoke.

Ye Mo put away the Qingling Pill in his hand and nodded.

The spirit ring in Mu Lao's hand flashed, and between the flips of his hand, six jade slips appeared.

"This is the introduction and picture of the spiritual material, there are 90,000 kinds of first-grade spiritual materials, 50,000 kinds of second-grade spiritual materials, 30,000 kinds of third-grade spiritual materials, 9,000 kinds of fourth-grade spiritual materials, 5,000 kinds of fifth-grade spiritual materials and 1,000 kinds of six-grade spiritual materials. You take it back and examine it carefully, and you have to understand the level of extreme detail of each herb, and when you can recognize each spiritual material at a glance, you can come to me again. The old man commanded lightly, I think this nearly 200,000 spiritual materials are enough for Ye Mo to see for nearly ten years, right?

The fairy world is a high-level plane, and even ordinary spirit masters have a lifespan of hundreds of years, so once the king becomes an emperor-level powerhouse, the lifespan is even more than a thousand, and ten years is just a time to close up in the eyes of the strong.

Mu Lao didn't care at all, but Mu Lao didn't know that Ye Mo didn't have the slightest awareness of this, his persistence that went deep into the bone marrow made him not want to quickly cultivate to the realm of tearing the shackles of the plane every moment, break the space and go back, and understand the past events that had entangled him for more than ten years...
