Alchemist Alliance, in one room.

"You can wait here with peace of mind, if what you say is true, there will be no shortage of spirit stones, and we will also let you go. After speaking, the middle-aged man pretended to fall asleep on the chair and no longer paid attention to Lin Feng.

Lin Feng sat on the chair and closed his eyes slightly, thinking about what he would say after seeing Zhou Quan.

But only three days have passed.

Lin Feng couldn't help but be anxious, and was just about to open his mouth to ask the middle-aged man when Zhou Quan would return, when the people in the room were pushed open from the outside, and an old man in a black shirt and white hair strode into the house, this person was Zhou Quan.

"Elder Peng's transmission note is this person?" Zhou Quan pointed at Lin Feng.

"That's right, Elder Zhou, please take a look. The middle-aged man took out a Linzi brand potion.

After Zhou Quan took the potion and examined it carefully, he said, "This is exactly the potion refined by Lin Shan, and the mark on the jade bottle will not be wrong." ”

"I don't recognize most of these potions, have you explained to you that Lin Shan Daoyou?"

Hearing the question, Lin Feng got up and clenched his fists, and briefly explained the efficacy and characteristics of several special medicines.

The middle-aged man and Zhou Quan were both surprised and delighted after hearing this, and no longer doubted Lin Feng's words.

Both of them were masters of the Three Grades of Elixiries, and although they had never heard the names of several of these special potions, they had no doubts about the quality of the potions.

Once these high-quality elixirs flowed out, they would greatly enhance the reputation of the Alchemist Alliance and Lin Shan's reputation.

The smile on Zhou Quan's face slowly retracted, and said, "You saw Lin Shan Daoyou tell him, come to Zhongtian City, beware of Zuo Zhongshan!"

Hearing this, Lin Feng's heart sank, and he nodded quietly.

Afterwards, the middle-aged man and Zhou Quan accompanied Lin Feng to receive nearly one and a half million spirit stones at the exchange office, and 15,000 alliance contribution points.

Because the Linzi brand potion is very popular, Zhou Quan and the middle-aged man made the decision to recycle the Linzi brand potion at the price of 3,000 spirit stones per bottle.

Lin Feng was secretly happy in his heart, in this way, he didn't need to sell the third-grade elixir anymore, and his net worth already exceeded two million and three hundred thousand spirit stones, which was enough for the formation.

He didn't want to waste time, so he said goodbye and left the Alchemist Alliance and rushed back to He's house.

Inside the living room of the He family.

"The juniors have already gathered enough spirit stones, if it is convenient for the seniors, I want to start now. As he spoke, Lin Feng took out a jade plate.

The middle-aged man took the jade plaque and put it away, and said in astonishment, "I really didn't expect that you would be able to scrape together this huge amount of money in a few days, you copied the secret method to me, confirm that the secret method is correct, and we can start immediately." ”

On the way here, Lin Feng had already burned the Yin and Yang Returning Technique in the blank jade slip, and he did not hesitate to take out the jade slip and hand it to the middle-aged man.

Reading the jade slip, the middle-aged man muttered excitedly, "Yin and Yang Technique!" I have never seen such a subtle secret method...... You come with me!"

The middle-aged man was very happy, put away the jade slip as if it were a treasure, and made a gesture of please.

Lin Feng followed the middle-aged man into a huge stone room built under the attic, in the middle of the stone room there was a bluestone plate with a height of one zhang and a diameter of twenty zhang, carved with a one-foot-sized rune.

On it, there is a yin-yang fish pattern as big as the stone plate, and there are two bluestone pillars engraved with runes and runes one zhang thick and nine zhang high.

The middle-aged man looked proudly at the formation in front of him and said, "You put two million spirit stones into the groove on the stone plate, and then sit cross-legged in the middle of the stone plate. ”

"Good!"

Lin Feng jumped onto the stone plate without hesitation, and with a wave of his hand, the spirit stones piled up a hill in the groove, and he crossed his knees to the middle of the formation.

"Let's start now. ”

The middle-aged man sat cross-legged on the spot, pinched his hands and smashed a half-foot-long green light into the formation stone plate, and in an instant, the black light on one stone pillar flashed slightly, and a faint white light flashed on the other stone pillar.

Suddenly, Lin Feng felt a strange suction force around his body out of thin air.

The vitality in the body turned into a light green mist, slowly drifted out of the body and disappeared into the white stone pillar, and then a lot of light gray mist floated out of the body, and disappeared into the black stone pillar.

As time passed, more and more mist drifted out of his body, and his appearance slowly aged, but he didn't feel any discomfort in his body.

"Remnant Soul, are those pale gray mist the vitality in my body?" Lin Feng asked in his heart.

"That's right!" replied the remnant in the affirmative.

Hearing this, Lin Feng put his mind at ease and didn't speak, and slowly closed his eyes.

Twenty days passed.

The middle-aged man had been sitting cross-legged in place, and every few days he would carefully observe the formation, and only after confirming that the formation was working properly would he enter the state of pranayama with his eyes closed again.

And Lin Feng, who was in the middle of the formation, was already full of white hair, and a lot of wrinkles appeared on his face, looking like an old man in his sixties.

At this time, the two different colors of mist floating out of his body decreased a lot.

About 10 more days passed.

When the two million spirit stones on the formation were about to be consumed, the last two traces of vitality in Lin Feng's body were also drained by the formation.

He was shocked, and for the first time he felt that death was so close to him, as if he would leave this world in a few breaths.

At this moment, the middle-aged man with a solemn face shot a green light into the white stone pillar, and the dazzling white light on it flashed and disappeared.

An incomparably pure pale green mist rushed into his body from the stone plate under Lin Feng's body, and instantly transformed into his own vitality, and the feeling of imminent death suddenly disappeared without a trace.

At this time, he felt that the vitality in his body was extremely pure, but this vitality could only provide him with about half a year's lifespan.

The middle-aged man exhaled heavily, got up and smiled, "The whole process of withdrawing vitality is very smooth, and the hidden dangers in your body have been completely removed. ”

"Thank you, senior!"

Lin Feng got up and clenched his fists, his voice was old and hoarse, his appearance looked like he was in his eighties, and his hair was gray and wrinkled.

The middle-aged man smiled and nodded.

Out of the He family.

Lin Feng didn't plan to return to the Jade Spirit Sect for the time being, he didn't want to go to see Ling Xue'er, Zhang Dazhong and Wang Xiaotian in such an old state of Dragon Zhong, so as not to make a few people worry about him.

He found a large inn in the city for monks to live in, and rented one of the best rooms at a high price of 3,000 spirit stones per month.

Telling the innkeeper not to disturb him for half a year, Lin Feng entered the house, closed the door, and crossed his knees on the futon.

"Remnant Soul, can the wooden character technique restore my longevity for more than two hundred years?" Lin Feng asked in his heart.

The remnant soul explained, "The wooden character recipe is not strong enough to have the ability to surpass the Heavenly Dao to increase your longevity out of thin air, so wouldn't you be immortal?"

Lin Feng asked puzzledly, "Then why can the wooden character recipe produce a lot of vitality before extracting vitality?"

The remnant soul thought for a moment and said, "You also said that it was before the withdrawal of vitality, due to the passage of normal years and the artificial withdrawal of vitality, the wooden character formula cannot be replenished for you. ”

Lin Feng nodded helplessly, he wanted to condense the five-colored golden pill as quickly as possible to obtain a large amount of longevity, and restore his original appearance as soon as possible.

At this time, Lin Feng didn't know about it.

The second-grade high-grade special elixir he refined had flowed out of the Alchemist Alliance more than twenty days ago.

Many Linghai stage monks have purchased and taken this potion, and their combat power has increased several times in a short period of time, not only that, but the special effect produced by the potion, which surprised those monks.

Therefore, in just a few days, this batch of Lin Zi brand potions caused an uproar in Zhongtian City.

That's it.

A few days later, the three spring elixirs were copied to eight thousand spirit stones, while the other five special elixirs were copied to the high price of one bottle of ten thousand spirit stones.

Even the Blue Spirit Milk, which quickly recovered the spiritual power of the Spirit Sea Stage cultivators, was copied to a bottle of four thousand spirit stones, and even so, it was still difficult to find a medicine.

Since then, in front of the Alchemist Alliance, there are clerks or shopkeepers of more than a dozen shops every day, asking to order Lin Zi brand potions again.

Since no one in the Alchemist Alliance knew when Lin Shan would come to exchange the potion again, those merchants did not get a clear answer.

On this day, on the fifth floor of the Alchemist Alliance, there was a small living room.

An old man with a round face wearing a green shirt and kind eyebrows frowned slightly and looked at a delicate jade bottle in his hand.

Not far away, two people stood respectfully, one of them was Zhou Quan, and a middle-aged man in a purple brocade robe.

The round-faced old man muttered to himself, "Extremely Yin Cold Ice, this is the first time the old man has heard of the name and efficacy of this potion. ”

Lin Shan deliberately controlled the quality of the medicine at the top grade, and according to the old man, he could easily improve the quality of the medicine to the top grade. ”

"His potion skills have a solid foundation, and his alchemy skills are exquisite, and even the old man is ashamed of himself for handling some details. ”

The middle-aged man and Zhou Quan glanced at each other, they didn't expect that the round-faced old man in front of them had such a high evaluation of Lin Shan.

Zhou Quan was even more surprised, the round-faced old man was a Great Perfection Cultivator of the Elixir Period, and he was also a Potion Grandmaster, even the old man said something that was ashamed of himself, so how superb was Lin Shan's Potion Technique?

Zhou Quan was secretly delighted, he admired himself at this time, and he did not hesitate to make the decision to befriend Lin Shan at that time.

The old man asked, "Pengyuan, what is the reaction after this batch of potions flows out?"

Hearing this, the middle-aged man named Peng Yuan respectfully hugged his fists and said, "The alliance leader doesn't know that this batch of potions has caused a great sensation in Zhongtian City. ”

"Many monks who have taken potions have praised the special effects of potions, but they don't care about the side effects with Ben Hao, and the reputation of the Alchemist Alliance and Lin Shan has increased greatly again. ”

The old man nodded happily and said, "If you have a chance, I want to meet that little friend of Lin Shan in person, okay, you guys go down." ”

"Yes!"

Zhou Quan and Peng Yuan respectfully replied and exited the living room.

"Who will Lin Shan's master be, and where do these potion formulas come from?" the old man looked at the jade bottle in his hand and muttered to himself in a puzzled voice.

Bang bang, there was a knock on the living room door.

"Come in. ”

The old man's voice fell, the door was pushed open, and a young woman in a snow-colored dress walked in lightly, this person was Ling Xue'er.

"I've seen the teacher!" Ling Xue'er smiled sweetly and bowed slightly.

"Apprentice, have your potion skills improved in the past few days?" the old man smiled and nodded.

"I can't hide anything from your eyes, this is the medicine that the disciple refined some time ago, please take a look at it. Ling Xue'er took out a beautiful jade bottle, walked a few steps quickly and handed it to the old man.

The old man put the jade bottle in his hand on the wooden table beside him, opened the potion that Ling Xue'er had refined, and sniffed it carefully.

"Dan Yuanlu...... The liquid medicine is not pure enough, the dosage control is not very accurate, the efficacy is average, and the drug is of medium grade!"

After a pause, the old man continued, "Dan Yuan Dew is one of the more difficult to refine among the third-grade low-grade elixirs, and you have achieved such results in less than a year after entering the third-grade level, which has already exceeded the expectations of the teacher. ”

Receiving the teacher's appreciation, Ling Xue'er was very happy and smiled sweetly.

"It just so happens that I have a bottle of high-quality potion refined by the members of the alliance here, you can refer to it. As he spoke, the old man picked up the jade bottle on the table.

"Oh, the teacher has such a high opinion of this potion, let me see. Ling Xue'er was a little unconvinced, and took the jade bottle with a smile.

Immediately, she saw at a glance that the jade bottle had the mark of the word Lin, and the good-looking smile on her face suddenly converged, replaced with a shocked expression, her hands couldn't help trembling slightly, and she almost threw the jade bottle on the ground.

After a few breaths, Ling Xue'er came back to her senses and asked excitedly, "Teacher, where did you get this potion? Do you know what the name of the person refining this potion is, and where is he?"
