She hurriedly turned her head to look, and saw an old man with gray hair slowly coming out from behind the screen.

The old man's figure was not tall, only a little taller than Mu Yan.

The hair was as white as snow and stood up with a jasper hairpin.

The beard is also snow-white, long hanging down to the chest, coughing, the old man strokes his beard, quite a bit of fairy wind bones.

But Mu Yan looked at the old man, but he always felt a strange sense of disobedience.

After observing for a long time, she saw that the old man's eyes were too clear, too translucent, and too round.

And the mouth, although most of it is covered by a white beard, you can still faintly see the pink lip flap.

"Presumptuous!" A sharp low shout came, "Bow your head, who allowed you to be a teacher?!" ”

This voice was mixed with powerful coercion, which startled Mu Yan, and he hurriedly lowered his eyes, not daring to look at it again.

In his heart, he became more and more curious, "You are the Holy Ancestor Medicine King?" ”

"Of course!" Han Chujiu snorted coldly, "Apart from me, is there a second person in this world who can become a Saint Ancestor-level refiner?" ”

After boasting, Han Chujiu said, "Do you want to get the inheritance of the Medicine King as a teacher?" ”

Mu Yan nodded without hesitation.

"Then you first refine a furnace of elixir for the teacher to see."

With a casual wave of words, some of the common elixirs in the Xiuzhen Continent were piled up in front of her.

One of the alchemy furnaces stuffed with garbage also arrived in front of Mu Yan.

Han Chujiu blushed when he saw the garbage inside, and hurriedly waved his hand to clean up the garbage: "Let's refine it here." ”

Mu Yan did not hesitate, and quickly selected the elixir to refine it.

What she refines is still her best barrier-breaking pill.

As the Dan fire rises, throw the elixir into it one by one and slowly melt it.

Han Chujiu's voice sounded in the hall from time to time.

"Huh? What kind of formula is this, how come I haven't seen it before? ”

"Tsk, it's a little interesting, it can actually stimulate instantaneous potential, clear and wise, if you take it, it should help people break through the bottleneck." You little girl is really interesting. ”

However, when Mu Yan controlled the flames and began to fuse and condense the melted elixir.

Han Chujiu was furious, and scolded: "Violent destruction of heavenly things!" It's too tyrannical! Such a good Danfang is actually refined in such a garbage way! Which idiot taught you this method of fire control and condensation? It's just stupid, idiot, stupid! ”

Mu Yan stopped the movement in his hand in a daze.

She couldn't refine anymore, and if she continued refining, she was afraid that this medicine king would be angry and pick up an alchemy furnace and smash it on her head.

Han Chujiu blew his beard and glared, and roared loudly: "Say, in the end, that turtle king bastard taught you to control fire and refine the pill!" This is killing genius, Lao Tzu is going to strangle this idiot to death! ”

Mu Yan touched his nose and said embarrassedly: "No one taught me, I found it all by myself." ”

The Elementary Dan Dao Daquan and Intermediate Dan Dao Daquan in the Heavenly Demon Qin Space taught relevant theories, but they did not actually teach her how to control fire and how to condense Dan.

In fact, words alone can't teach this thing.

Therefore, Mu Yan felt the changes in the elixir inch by inch according to the Danfang and the process of alchemy, and figured it out by himself.

This time, it was Han Chujiu's turn to be shocked.

Myself...... Groped out?!

The most difficult thing in alchemy is fire control and condensing pills, and ordinary alchemists may not be able to master these two aspects after being taught by famous teachers for several years.
