When it comes to cultivating immortality, it naturally starts with upgrading the herb garden.

Feng Sancai looked down at Song Chen kneeling on the ground, a disdainful smirk playing on his lips, but he quickly regained his composure and said:

"Get up. Take these spiritual herbs. Now, refine a batch of Crimson Flame Pills and show me."

A basket of spiritual herbs was tossed in front of Song Chen, which stirred his heart.

This is all money!

What delighted him even more than this was Feng Caisan's one-on-one guidance in alchemy!

It's well known that cultivators at the late stage of Qi Refining are rare, let alone Feng Sancai, who is also a second-grade alchemist. He is extremely rare, and giving guidance to someone would surely cost an astronomical fee.

Even when he studied under Feng Sancai, he never directly instructed anyone; he always gave indirect guidance and casual pointers.

Now, however, Feng Sancai is going to give Song Chen guidance for free.

Thinking of this, Song Chen dared not slack off, fearing that Feng Sancai would return. He even became more efficient and hurriedly began refining pills.

Feng Sancai then carefully observed from the side, constantly pointing out his problems.

"Be gentle! Don't ruin the medicinal herbs!"

"it is good."

Song Chen listened attentively, his hands never stopping.

......

"Handle with care! Do you think these spiritual herbs are trash?! You're just throwing them into the alchemy furnace!"

"good!"

Song Chen slowed his movements a bit, and Feng Sancai nodded slightly upon seeing this.

......

"Your fire power has improved somewhat, but your use of spiritual energy is still a mess. However, the quality of your spiritual energy has improved, which should be related to your cultivation level. Try combining your core first, and then go to the spirit field to practice properly later!"

"I will obey Master!"

Song Chen nodded in agreement and began to combine the pills.

......

"Two failed pills, four inferior pills, and four successful pills, resulting in a success rate of 40%, which is neither high nor low. The number of inferior pills has improved somewhat. If the pill-making process is mastered, the success rate could be increased by another 20%... Hey! What are you going to do?"

"Reporting to Master, go to the spirit field to practice the use of spiritual energy."

Song Chenyan appeared neither humble nor arrogant, but submissive.

"...Wait a bit, I'll forge a batch for you to see. You can light the fire, watch carefully, and learn well!"

Song Chen's lips curled up slightly as he walked back from the doorway, bent down to carefully control the fire, and observed the details of Feng Sancai's alchemy process.

Feng Sancai's alchemy process was extremely efficient; every movement was exactly the same as described in the book, without any unnecessary actions.

"Now all that's left is to combine the pills. Did you notice anything in the previous steps?"

"Master's movements are clean, unlike mine which are messy."

Feng Sancai remained calm and continued:

"Anything else?"

"...My master's cultivation level is at the late stage of Qi Refining, and his spiritual energy is pure enough that he can directly attach it to his hand and put it into the furnace, while I can only use spiritual energy to wrap the elixir externally."

Feng Sancai's lips curled up almost imperceptibly, and he raised an eyebrow:

"Anything else?"

Song Chen shook his head, unable to discern anything else.

To be honest, it's already quite remarkable that someone with his alchemical expertise could see the problems arising from cultivation level. Anything else is just asking the impossible and is pure fabrication.

But Feng Sancai was still not satisfied and kept asking questions, trying to extract the answer from Song Chen's mind.

After repeatedly confirming that Song Chen couldn't say it, he frowned slightly, and a hint of annoyance flashed in his eyes.

Then, with a wave of his hand, the fire at the bottom of the furnace immediately shrank by more than half. He opened the cauldron, and a strong aroma of elixirs wafted out and filled the entire room.

Song Chen stood up and stared at the scene inside the alchemy furnace. He was shocked at just one glance.

Two inferior pills, eight perfect pills!

An 80% success rate in achieving the desired pill!

Seeing Song Chen's expression, Feng Sancai shook his head rather arrogantly:

"I'm getting old. Before, my success rate with first-grade pills was a solid 90%, but not anymore!"

Despite his self-deprecating manner, his eyes clearly revealed an air of arrogance.

"Master's skills are profound, known to all. Who in Huanbei City doesn't know this?"

Song Chen learned a lot of experience and skills, so he naturally followed suit and flattered her.

Feng Sancai listened with delight, and Song Chen, seeing this, pressed his advantage and asked a few more questions, all of which were answered one by one.

Suddenly, Feng Sancai's expression turned serious, and he asked, "Do you know how to deal with inferior pills?"

"Feed them to demonic beasts, use them as fertilizer for medicinal purposes, or use them as raw materials for refining other elixirs."

To everyone's surprise, Feng Sancai didn't answer. Instead, he took out a silence note and stuck it on the wall.

"What you've said is all correct, but today I'm going to teach you a unique skill. Can you guarantee you'll never pass it on to anyone else?"

Song Chen understood that this was what Feng Sancai truly wanted to impart.

Those were just tests to see if he had made any progress in alchemy.

He immediately adopted a stance: "Words are meaningless; let's establish a legal framework!"

Song Chen immediately focused his spiritual energy in his right hand. Feng Sancai, revealing an expression of admiration and triumph, also focused his spiritual energy in his left hand, shook hands with him, and said:

"What should be the punishment for actively leaking this information?"

"Cultivation power diminished, lifespan greatly reduced, forever barred from reincarnation!"

Then, a wisp of spiritual energy, thinner than a hair, drifted from Feng Sancai's left hand and entered Song Chen's spiritual energy.

Similarly, Song Chen's spiritual energy also entered Feng Sancai's spiritual energy.

Thus, the vow was fulfilled.

If he breaks the vow, the spiritual energy within Song Chen will activate and form a causal chain, forcibly killing him to fulfill the oath.

This is Feng Sancai's second talent besides elixirs: the art of contracts.

This method can also be initiated by a third party; as long as the person who casts the spell does not die, they can continue to act as a guarantor for the transaction.

Feng Sancai was in a great mood. He looked Song Chen over a few times. This boy used to be quite impetuous. Although he had talent, he was not capable of great things. Choosing him was just a last resort.

The changes now are likely due to family troubles and external pressures, which have given rise to new wisdom, a kind of destruction followed by construction.

Moreover, this is a good thing for Feng Sancai. Song Chen has no relatives or friends, so as someone who helps him in his time of need, he naturally becomes his closest person.

Thinking about it that way, he could indeed rest assured to pass on his life's skills and begin that matter!

"Very well! In that case, I will tell you about other uses for inferior pills!"

After saying that, he took out two inferior pills and carefully examined their patterns.

Before long, a pale blue light emanated from his hand.

Under Song Chen's puzzled gaze, one of the pills changed its pattern in Feng Sancai's hand, forming a dividing line. One side was completely black, while the other side looked like a newly born pill.

The other one is the same.

Then, a miraculous thing happened.

The two pills in Feng Sancai's hands broke in two along the dividing line, and then they were combined to form a new pill and a useless pill.

Feng Sancai picked up the newly combined pill, checked it repeatedly to confirm that it was correct, and placed it together with the previous eight pills. He could not see any difference between them.

This... is simply miraculous.

Song Chen was stunned.

Everyone knows that inferior pills and waste pills are useless, but no one knows that there is such a miraculous way to process inferior pills.

This should be Feng Sancai's unknown third talent—the legendary Pill-Making Technique.

"You should have heard of this technique; it's what outsiders call the elixir-making technique that turns the useless into the useful."

"In this way, the success rate of pill formation will be 90%."

He tossed the discarded pill aside, and it fell to the ground, shattering into pieces.

"Would you like to learn?"

Song Chen nodded frantically.

"This method cannot be accomplished overnight. You must first increase the success rate of the Crimson Flame Pill to 70%, and then I will consider teaching you."

Feng Sancai pushed open the door, intending to leave Song Chen alone inside to practice, but when he reached the doorway, he suddenly stopped and said:

"If you encounter any difficulties, you can tell your master. Don't limit yourself to alchemy."

Upon hearing this, Song Chen suddenly realized that his family's refined pills had no market, and perhaps he could discuss it with his master.

He immediately called out to Feng Sancai, "Master, wait a moment!"

"What?"

......

Song Chen and Feng Sancai talked about the family's process of refining mortal pills.

"Alright... in the future, make less of these kinds of pills; it damages the reputation of alchemists."

"...yes!"

"Take those refined Crimson Flame Pills."

What!

Song Chen stood there stunned in surprise, never expecting happiness to come so suddenly.

boom!

The door was closed, leaving only a ecstatic Song Chen behind.

One Crimson Flame Pill costs nine spirit stones. Including the ones he refined, there are a total of thirteen Crimson Flame Pills, costing one hundred and seventeen spirit stones!

However, compared to exchanging it for spirit stones, the Crimson Flame Pill has other uses for Song Chen.

That is the large amount of pure fire-attribute spiritual energy it contains, which is very beneficial for cultivators with strong fire spiritual roots.

Although Song Chen has a pseudo-spiritual root, his fire element spiritual essence is the strongest among the five spiritual roots, making him extremely suitable for consumption!
