After I cultivated immortality, I discussed the theory of lifespan with a long-lived spirit.

Chapter 23 Single Recipe for Peiyuan Dan

[You have successfully refined your first elixir: Rejuvenating Dew. Knowing the importance of elixirs for cultivation, especially in environments lacking spiritual energy, you have decided to search for the recipe for the Nourishing Essence Pill. Reward: Mastery of Nourishing Essence Pill Refining.]

A quest has been triggered.

Lin Er was slightly taken aback. The Qi-Nourishing Pill was the reward for the previous mission, and it seemed quite important.

He immediately returned to his room at the Broken Sword Tavern and retrieved the previous mission rewards.

A three-inch-long white porcelain bottle and four low-grade spirit stones landed in his hand.

Lin Er opened the small porcelain bottle and a rich medicinal fragrance wafted out. Inside the bottle were ten crystal-clear pills, brimming with spiritual energy.

"This Qi-Nourishing Pill has a much richer spiritual energy than spirit stones."

As expected of a well-refined pill, it is far superior to spirit stones.

Lin Er poured out a Qi-Nourishing Pill and put it in his mouth. It melted instantly upon entering his mouth, leaving a sweet taste, and a huge burst of spiritual energy erupted from it.

He quickly closed his mouth and eyes, sat cross-legged on the bed, and began to circulate his energy to refine the spiritual energy.

Lin Er quickly discovered that a Qi Cultivation Pill contained twice as much spiritual energy as a spirit stone, and it was also much purer, containing no impurities.

His speed in refining spiritual energy has increased significantly.

This highly efficient refining process made Lin Er extremely cautious, afraid of wasting even a single drop of spiritual energy.

His dantian gradually became scorching hot, with an unnamed fire burning inside, aiding in the refining of spiritual energy.

This seems to be an effect of the Pure Yang Sword Technique.

Lin Er never expected that the Pure Yang Sword Technique, which was clearly not a celestial technique, could still have such wonderful uses. Indeed, even the most ordinary things recorded in a technique still have their uses.

As the pure Yang sword intent rose, his mind was free of distractions, and the refining speed increased greatly.

I don't know how much time has passed.

After Lin Er refined the last trace of spiritual energy, his consciousness gradually returned, and he heard the chirping of birds in his ears.

He suddenly opened his eyes; it was already dawn outside the window, and early risers were already out and about.

"I started cultivating yesterday afternoon, and now a whole night has passed. I have actually refined three times the original amount of spiritual energy."

This Qi-Nourishing Pill is truly amazing.

Lin Er then realized that his attention had become somewhat scattered, and his body was both thirsty and hungry. He had been so focused that he hadn't noticed this at all.

He got out of bed, went downstairs to the bar and ordered breakfast. After filling his stomach, he went back to his room and went to sleep.

When Lin Er woke up again, it was already afternoon.

"The Qi-Nourishing Pill is a good thing. The mission requires me to find the pill formula. It looks like I can only try my luck at the herbal medicine shop again."

Lin Er picked up his sword, got up, and went to the herbal medicine shop.

He looked up and saw that the herbal medicine shop was closed, with a sign outside saying it was closed.

Just as Lin Er was about to leave, he heard the sound of pounding medicine coming from inside the shop. He leaned closer to the door and listened more clearly; sure enough, someone was pounding medicine inside.

Because the alchemy process here went very smoothly yesterday, he still preferred to obtain the recipe from this shop, so he knocked on the door.

Then, a weak, feeble voice came from inside the house.

"Can't you see? This shop is closed."

Lin Er said, "Boss, I'm here to buy the formula."

As soon as he finished speaking, the sound of pounding medicine inside the room stopped abruptly, and then the door opened.

Inside, flames roared and smoke billowed, and Carlisle poked his head out.

He had dark circles under his eyes, looked extremely haggard, and his face and hands were covered in soot, making him look quite disheveled.

Upon seeing Lin'er, Carlisle's eyes lit up again, and he excitedly exclaimed:

"Guest, you've finally arrived."

Lin Er looked puzzled and asked, "Did you need something from me?"

Carlisle, fearing that Lin Er would escape, pulled him into the house and then knelt down and hugged his leg.

"Please, teach me how to make medicine! I've been trying for a whole day and night, and I haven't succeeded even once."

Lin Er thought to himself, "I'm just a novice. How can I teach an alchemist how to make medicine?"

He politely declined, saying, "I'm just a beginner myself, I can't teach you."

Carlisle clung even tighter to Lin's leg, pleading:

"Please teach me, or I won't let you leave."

Lin Er stared in disbelief. Suddenly, he remembered something and asked:

"Are you talking about Ning... Mountain Orchid?"

Carlisle nodded repeatedly, his face contorted in pain, and said:

"After you left yesterday, I have been trying to make it with wild orchids. I have tried dozens of batches, but I have not succeeded even once."

Since yesterday, Carlisle has found that he has been unable to replicate the process. He tried to imitate Lin Er's alchemy process as much as possible, afraid of missing any details, and almost achieved a one-to-one replication, but still failed.

He deeply doubted his skills and no longer cared about making money; he only wanted to successfully refine the medicine.

Linton was somewhat embarrassed.

He used blood-clotting herbs, refined using orthodox alchemy methods, a skill that is probably impossible to teach.

Lin Er said, "I'm sorry, I really can't teach you."

Carlisle's expression changed slightly. He hadn't given up. As if he had made a decision, he gritted his teeth.

"Guest, if you are willing to teach me, I am willing to exchange my family's secret magic restoration potion recipe."

Lin Er shook his head and replied, "I really can't teach it."

Carlisle was still unwilling to give up, and said, "Guest, why don't you demonstrate it for me again? I'm still willing to trade the mana restoration potion recipe for it."

After a brief moment of consideration, Lin Er nodded.

Carlisle's expression softened, and he finally released Lin'er's leg and got up from the ground.

Without Lin Er lifting a finger, Carlisle, like a pharmacist's apprentice, proactively prepared the wild orchids and the necessary materials for him.

After receiving the mountain orchid, Lin Er placed it in front of him and sat down quietly.

Carlisle then picked up a pen and paper and began taking notes diligently.

So this is what needs to be done before making medicine; he had completely overlooked it before.

Carlisle was so angry that he slapped his thigh.

After Lin Er reopened his eyes, the mountain orchid had turned into blood-clotting grass. He easily ground it into powder and then refined it.

Two hours passed.

The familiar aroma of medicine emanated from the crucible, growing stronger and stronger.

Carlisle sniffed, his fingers trembling slightly, and his expression flushed.

Lin Er looked at his notes, which were filled with dense writing, and the handwriting was extremely neat.

Isn't this process very simple? Is it necessary to remember so many steps?

Lin Er withdrew his gaze, opened the lid, and an even stronger medicinal fragrance wafted out.

The two looked closely at the same time and realized they had succeeded.

Carlisle was overjoyed and quickly said:

"Guest, I'm here to test the medicine."

Carlisle pulled out a dagger and, without hesitation, slashed his own wrist, causing a large amount of blood to spray out and splatter onto the wall.

That's too cruel!

Are you out of your mind?

Lin Er was shocked and quickly put the Rejuvenating Dew into a bottle, then poured it onto Carlisle's wound.

In the blink of an eye, the bleeding stopped, and the wound healed at an extremely fast speed.

Upon seeing this effect, Carlisle suddenly burst into maniacal laughter.

"Haha, we did it!"

Lin Er felt that Carlisle was even more excited than he was, which was simply insane.

After a moment, Carlisle finally stopped laughing and said, "Guest, I am willing to buy this potion at double... no, three times the market price."

The materials and tools were provided by Carlisle, and the effects of this rejuvenating lotion are nowhere near as good as the genuine product.

After a brief consideration, Lin Er nodded.

Carlisle immediately took out 30 workshop coins.

Lin Er was somewhat surprised by this.

This treatment is so expensive?

They previously went to the Misty Forest to wipe out goblin lairs, and the bounty was only 10 workshop coins. Although there was extra income, this also shows how expensive healing potions are.

No wonder Carlisle is so crazy; wild orchids only cost a few dollars, this is pure profiteering.

Lin Er suddenly had an idea.

At this moment, Carlyle went back into the inner room, took out a parchment, presented it with both hands, and said:

"Guest, this is my family's secret recipe for magic restoration potion."
