The next day, Lin Yuxing was still the same as usual, getting up early in the morning to meditate and practice qi, and when he was done, he was proficient in the exercises.

It wasn't until noon that Lin Yuxing stopped to rest for a while, but what made him feel strange was that until now, Wen Lao still hadn't come out.

Last night, he couldn't wait, and wanted Wen Lao to refine the pill immediately, but Wen Lao wanted to say that the time had not yet come, and he would wait until noon when the sun was shining brightly.

Before Lin Yuxing could finish speaking, then Lin Yuxing was stunned, turning into a cloud of white qi and burrowing into his body and disappearing without a trace.

Now that the time has come, he still hasn't seen Wen Lao come out, Lin Yuxing is a little anxious, and is thinking about how to contact Wen Laoshi.

Elder Wen appeared behind him like a ghost, startling him.

"I thought you couldn't get out?" Lin Yuxing patted his chest, as if relieved.

Elder Wen just glanced at him, didn't say anything, and then walked into the cave by himself, looking left and right.

Just when Lin Yuxing was confused, he saw Wen Lao's hands sealed, and then waved his hand to the top of the cave, and then he heard a deafening sound.

Lin Yuxing was shocked in his heart, and reminded him: "Elder Wen, this is the Barren Mountain Range, and the sound is too loud to attract fierce beasts or cultivators. ”

"Hmph, what's the panic, didn't you see that I had already used my divine sense to form an enchantment?" no matter how loud the sound was, it couldn't be heard," Wen Lao snorted coldly.

Lin Yuxing looked at it with his divine sense in disbelief, and found that it was indeed as Elder Wen said, and now the entire mountain was protected by a layer of protective cover. Judging by its appearance, it should be the enchantment that Elder Wen said.

Lin Yuxing was extremely surprised that Wen Lao had arranged the enchantment quietly, and just when he wanted to see what Wen Lao would do next, he happened to see that in front of Wen Lao, a cave actually appeared.

Lin Yuxing curiously followed Wen Lao in, and what caught his eye was a cave the size of the Lin family's secret room, the cave was not as dark as he imagined, but as bright as day.

Lin Yuxing looked up at the top of the mountain, and this look made him dumbfounded.

The top of this cave actually leads straight to the outside, and the light inside is actually the real sunlight, if it weren't for Lin Yuxing seeing Wen Lao build it with his own eyes, I'm afraid he would think that this cave itself exists here.

Wen Lao's series of methods, Lin Yuxing was really impressed, and he looked at the top of the cave and couldn't speak.

"Why don't you go and get the herbs? ”

Just when he was stunned, Wen Lao's words woke him up, he hurriedly came out of the cave, held all the medicinal herbs in his arms, and then walked to Wen Lao and put it down.

Wen Lao pointed to a corner of the cave and motioned for Lin Yuxing to sit down as well, and Lin Yuxing did so.

After seeing that everything was ready, Elder Wen looked at Lin Yuxing and said:

"The first thing in this alchemy is to identify the herb and know whether it is warm or strong, positive or negative. If you make one wrong step, the elixir will turn into poison, you can hear clearly. ”

"Hear me clearly. Lin Yuxing replied solemnly.

Wen Lao nodded with satisfaction, and then waved his hand in the direction of Lin Yuxing, I don't know what it was flying towards Lin Yuxing.

When Lin Yuxing saw it, he hurriedly caught it and fixed his eyes to see that it was a piece of jade as big as a palm.

When Lin Yuxing turned over and over to see that he didn't understand, Elder Wen's words rang out and explained to him.

"This is the Hundred Herbs, which contains pictures of hundreds of herbs and their medicinal properties, which you must keep in mind. ”

Lin Yuxing suddenly realized, and he couldn't put down this jade piece, and he planned to take time out of it in the future to memorize this "Hundred Herbs".

"The next thing is alchemy, I will explain the specific steps to you one by one, if there is anything you don't understand, remember it first, and then ask later. Elder Wen explained again and again.

Lin Yuxing also nodded his head to show his understanding when he heard it, and then kept silent.

"The pill that you have refined this time is called Naqi Dan, which is specially used to improve blood qi, this pill is a top-grade four-star pill, and the medicinal materials required are: burning weeds, glazed buds, spider lotus, ......."

Wen Lao introduced it, and Lin Yuxing remembered it silently. In this way, Elder Wen took the trouble to explain all the medicinal properties and matters that need attention in it.

Although Lin Yuxing heard these things in a fog, he remembered them well, and he memorized them by rote.

After explaining all this, Wen Lao once again sealed his hands and recited silently in his mouth.

At this time, on the ground in front of him, a trace of blood was methodically carving runes that Lin Yuxing couldn't understand.

The runes depicted were all crooked, but when Lin Yuxing looked at it carefully, he felt that it was extremely neat and very weird.

There was a low sound of "hum", and the runes carved on the ground had ended at this time, but at this moment, Lin Yuxing suddenly felt a surge of heat on the ground, thinking that it was an illusion, but when he touched it with his hand, he confirmed that this was the truth.

After the runes on the ground were carved, the blood and qi floated to the mouth of the top of the mountain, and they were carved again, and in this way, in less than a cup of tea, two runes were formed.

At the moment when the rune was formed, the entire cave was already filled with heat, making Lin Yuxing sweat profusely and his mouth dry.

At this time, Wen Lao's handprint changed, and he saw that the upper and lower runes were close to each other, and it was this closeness that all the heat in the cave surged towards them, and Lin Yuxing suddenly felt that the temperature in the cave slowly returned to normal.

These two runes are like a space inside, absorbing all the heat inside, then storing it, and slowly moving closer together, constantly compressing, making the heat more pure.

This phenomenon surprised Lin Yuxing.

"Every alchemist must have his own Dan Furnace, and this is my Dan Furnace. Elder Wen said talkatively.

"Dan Furnace? You can form a Dan Furnace with two runes. Lin Yuxing still couldn't help but ask.

As for the Dan furnace, he had seen it in the book, and the Dan furnace was made by the alchemist with various precious materials, and it was a physical existence.

But like Wen Lao, a Dan furnace that can be formed directly with runes, this is the first time he knows about it.

"My Dan furnace is different from the secular Dan furnace, my Dan furnace is called the Heaven and Earth Creation Furnace, with heaven and earth as the furnace, with the fire of the earth's lungs and the essence of the sun as the fire, the elixir refined by it can be several times better than that refined by others. Elder Wen said with some pride.

Lin Yuxing suddenly realized, no wonder he felt that the ground was hot just now, and the air was also hot, it turned out to be the fire of the earth's lungs and the essence of the sun.

At the same time, Lin Yuxing finally understood why Wen Lao chose to refine the pill at noon during the day, because noon is the time of the day when the heat is the highest, which is conducive to absorbing heat.

Although he didn't understand these Lin Yuxing, he was sure that not everyone could do these methods, and unconsciously, he had a high opinion of Wen Lao's strength again.

As he pondered, the heat collected by the Heaven and Earth Creation Furnace had reached its climax, and it could be seen that it was already fiery in the middle.

At this time, Wen Lao did not drag the slightest mud and water, and the medicinal materials on the ground with one hand and one hand flew to the Dan furnace to refine, forming a mass of green liquid, floating in the furnace without a support.

Looking at Wen Lao's comfortable appearance, Lin Yuxing secretly admired, and at the same time had some expectations.

After a few hours, the cave was finally filled with the fragrance of medicine.

Lin Yuxing took a deep breath and felt refreshed, which made him intoxicated.

Looking at this Dan furnace again, the pills at this time are no longer more than ten clusters of green liquid, but have formed two round pills, which are dripping and rotating in the Dan furnace.

"Up!"

Boss Wen shouted, only to see that the originally stable rune actually tilted out slightly, revealing a gap, and the two pills inside flew out of the gap and floated in front of Elder Wen and kept turning.

Elder Wen unhurriedly took out a jade bottle, and sucked the pill from the mouth of the bottle, and the pill flew in like a fish.

Then, Elder Wen waved his hand at the Heaven and Earth Creation Furnace and snorted softly:

"Scatter!"

I saw that the two runes "poofed" and turned into a little starlight.

And Lin Yuxing only felt that a heat wave swept in front of him, but it disappeared without a trace before it reached him, as if it had never been, which made Lin Yuxing amazed.

He has finally seen Wen Lao's alchemy, and all this can only be described as unfathomable.

"This is the Naqi Pill, take one pill every five days, and after absorbing all the medicinal power, the cultivation can be restored. Wen Lao threw the jade bottle in his hand to Lin Yuxing's body and said lightly.

"Thank you, Elder Wen!" Lin Yuxing hurriedly caught it, then stood up and saluted Elder Wen and thanked him.

Elder Wen waved his hand at him and said, "It's okay, you go find the best time to take the pill, recover your cultivation as soon as possible, and I'll meditate here to recover." ”

Lin Yuxing also had this intention, so he simply left.
