After Wu Renyi saw that the magma vortex below was getting smaller and smaller, he immediately opened his mouth in some surprise.

"Little rabbit, where did your spiritual fire come from?

"Well, this is something that Master Zun specially prepared for me to use for alchemy. ”

Integrity value deducted ten!

Wu Xin, who originally wanted to be proud for a while, couldn't get up at all now.

Just because of this imaginary master, he has almost been deducted hundreds of integrity points!

"I see!"

Wu Renyi nodded, and then said to Wu Xin, "But if you have this spiritual fire, you can completely suppress those boys, don't accept this fire first, I'll call those boys back first, and you can show your hand in front of them later." ”

"Show a hand?"

"Well, just show your ability to control fire a few times! Also, you will be called ...... in the future It's called Wu Yan, a fifth-order Dan Master, Wu Yan!"

Wu Xin: "......"

Wu Yan: This name is so familiar!

......

"Ye Yun Ye Lei, you little rabbit cubs are all back to Lao Tzu! The fire vein has been suppressed by Master Wu Yan and Wu!"

After discussing with Wu Xin, Wu Renyi shouted directly at the entrance of the cave.

Outside the valley, Ye Yun and the others, who were still fleeing frantically, couldn't help but reduce their speed when they heard this.

"Master Wu Yan, could it be the black-robed man just now?" Ye Yun couldn't help but think in his heart.

"Brother Yun, I seem to hear Uncle Wu calling us back. Ye Lei said to Ye Yun.

"Well, I heard that too" Ye Yun nodded.

"Shall we go back then?"

"Go back! Although when we came, my father warned us that Uncle Wu was not a good thing, but it was a matter of life and death for us, and he probably wouldn't joke about it!"

After Ye Yun thought about it, he decided to turn his head and go back to take a look.

Ye Yun's group of people did not grow up in Tonglin City, they had lived on the Red Cloud Continent since they were children, and they were not many miles away from here.

The Red Cloud Continent is also the place where Wu Renyi has been growing up.

Then, Ye Yun and the group turned back the same way.

When Ye Yun and the others, with a nervous mood, drilled into the cave again, the scene that came into their eyes made them open their mouths wide!

I saw that on the calm magma river, a black-robed monk with a burning python on his feet was walking back and forth as if nothing had happened!

Foot on the hot river?!

What kind of realm is this black-robed man!

"Hiss~"

Ye Yun and the others suddenly gasped collectively!

Because they saw that the black-robed man actually stretched his hand into the river of flames!

The black-robed man's hand was 'soaked' in the river for a while before he took it out of the lava again.

This scene directly made Ye Yun and the others look straight in the eyes, because they found that after the black-robed man took his hand out of the magma, his sleeves were exactly the same as before, undamaged!

"Hiss~"

"Ye Yun Ye Lei, this is Master Wu Yan Wu in front of me! I specially spent a sky-high price, please come to teach you alchemy, you must learn it for me well in the future!

In the end, Wu Renyi's voice suddenly became fierce!

"I heard you!"

Ye Yun and the others swallowed their saliva, and then replied loudly in a proper manner.

"Well, you guys go and meet Master Wu, do the disciple ceremony!"

"Yes!"

Ye Yun (Ye Lei, Wu Ying...... I've seen Master Wu!"

Ye Yun and the others saluted Wu Xinshen, and his head was almost lowered to the ground.

"Hmm"

Seeing this, Wu Xin felt that it was almost over, so he stepped on the Yan Python and went up to the shore from the magma river.

After going ashore, Wu Xin put Xuan Huangyan away, and then said in a hoarse voice, "I will only teach you for nine months, as for how much you can learn in these nine months, it depends on your own creation!"

The first sentence Wu Xin said made the hearts of Ye Yun and the others tighten suddenly.

"Yes, the disciple knows!"

"Well, let's go, without further ado, we'll start now!"

As he spoke, Wu Xin pretended to be and walked towards the row of Dan furnaces placed next to him.

These Dan furnaces are placed very carefully, and there are three zhang apart between each Dan furnace.

And under each Dan furnace, there is a fire starter, which is used to draw out the earth fire in the fire veins below.

Bang!

Airplanes~

Walking up to a silver-white Dan furnace more than half a person high, Wu Xin slapped the Dan furnace directly on the stomach.

"The first step of alchemy is to light the furnace! The furnace has two functions, one is to clear the ashes of the furnace, and the other is to identify the quality of the Dan furnace. ”

"I'll knock again, and you listen carefully. ”

Bang!

Buzz ~ Buzz

"When the furnace is lit, the sound is even, take this silver-white Dan furnace as an example, the tremor is strong and weak, it is obvious that the texture of the Dan furnace is uneven, and the alchemy with this Dan furnace is light and expensive, and the heavy is to fry the furnace. ”

"So this stove, waste one!"

Rumble!

As he spoke, Wu Xin's right hand was directly pressed on the stove, and then Xuan Huangyan skyrocketed instantly!

Sneer~sneer......

Under Wu Xin's Xuanhuang Yan, this silvery-white Dan furnace actually melted at a speed visible to the naked eye!

The silvery-white iron juice hit the ground with a strange snorting sound.

Boom!

Boom!

This scene made Ye Yun and the others feel a chill in their hearts, and then they swallowed their saliva in unison.

This old guy is terrible, a second-order Dan furnace, and if he says that he will melt away, he will melt away.

"Okay, let's start with the skills of lighting the furnace, the first step of lighting the furnace, the earthquake is very simple, find the pulse of the Dan furnace, and smash it hard. ”

"Master Wu, what is the pulse?"

"The pulse mouth is a special position of the Dan furnace, generally in the five or three places of the Dan furnace, that is, this circle is called the pulse mouth, and there are skills when smashing,......"

"The second step of lighting the furnace, listen! After shaking the furnace, the sound of the furnace is crisp and even, the second is uniform but rough, and the second, the sound is neither uniform nor crisp......"

Next, Wu Xin took Ye Yun and the others, lit up one stove after another, and finally found that among the twenty Dan furnaces prepared by Wu Renyi, thirteen were defective products!

After watching Wu Xinlian melt thirteen Dan furnaces, Wu Renyi's heart twitched in pain, this Nima is all money!

"After the stove is finished, let's move on to what to do with the elixir. ”

"Everything that has spirits in heaven and earth can be used in medicine! plants and trees, monsters, and even monks...... Yes!"

"Hiss~"

"Have you heard of the famous Absolute Yin Pill? This Absolute Yin Pill is made from the number of ninety-nine, and the female cultivator Yuan Infant born in the lunar year is the main medicine!"

"Forget it, let's not talk about this, let's continue to talk about this method of dealing with spirit grass......

Wu Renyi left that afternoon, and he went back to prepare the Dan furnace again......
