Nishiyama Hokyo, the Cheng family's pharmaceutical factory, the Liang sisters' laboratory.

After more than a month and hundreds of batches of pills, Li Mu finally succeeded in refining the Soul-Returning Pill.

Looking at the five pale purple pills in my hand, I felt a surge of emotion.

If it hadn't been unintentional, adding *Clematis chinensis* to the elixir might have prevented it from ever being made.

After hundreds of failed attempts at alchemy, he discovered the problem: the purified soul essence lacked activity.

Although licorice has little medicinal value and is very common and inexpensive, it is a versatile type of licorice.

A fresh stalk of sage contains not much active substance, but it is precisely what is lacking in the essence of soul liquid.

If it weren't for fresh *Clerodendrum trichotomum*, this pill-forming effect might not be achieved.

It must be said that, for something to succeed, the element of chance within the inevitable is even more important.

The five pills in Li Mu's hand, aside from the medicinal fragrance they emitted, weren't even of the lowest grade.

However, this does not mean it was a failure, because with this foundation for elixir formation, the correct direction for elixir formation has been found.

There was still one-third of the Soul Liquid essence left. His initial idea was to use quantitative change to influence qualitative change, thinking that using more would lead to the formation of the pill.

After refining several batches, he discovered that adding more soul essence was not necessarily better, so he began to reduce the amount of soul essence used.

Only five drops of soul essence were added to this batch of pills.

Even if the pill is successfully formed now, this dosage is not the most accurate.

Multiple trials are needed to find the precise dosage.

With the current experimental methods and the amount added to each batch of pills, the remaining soul essence can still be used to refine dozens more batches.

.

Although the Liang sisters no longer went to observe Li Mu's alchemy process in the same laboratory, they kept a close eye on him.

After watching Li Mu finish refining the first batch of pills and then remove the fire, I sensed something was different.

Seeing him staring blankly at the pill in his hand, and the joy on his face and in his eyes, they knew that Li Mu had successfully refined the pill.

In the same laboratory, over a period of more than ten days, they only met with Li Mu two or three times.

Although they didn't see him, they knew that Li Mu had encountered considerable problems with his alchemy this time, as they had used up all the supplementary medicines he prepared each day.

Therefore, their mood soured along with Li Mu's failed alchemy attempt, and the only thing they could do to help was to prepare more auxiliary medicines.

Seeing the hint of joy in Li Mu's eyes, the two of them felt much better.

"Sister Xiaoxiao, could you please go to the storeroom and get me some more fresh grass? I'll need it later."

Seeing the Liang sisters smiling at him, Li Mu spoke directly.

If it weren't for the two sisters helping to prepare the auxiliary medicines during this period, his alchemy experiments wouldn't have gone so smoothly.

After Liang Xiao brought back the herb, Li Mu sat on the sofa in the laboratory and shared some of his recent insights and experiences in alchemy with the two of them.

Refining elixirs requires talent, as well as continuous understanding and improvement of the refining techniques and processes.

From the day Li Mu began teaching the two sisters alchemy, he imparted all his knowledge to them, and the two sisters studied extremely diligently.

While Li Mu was speaking, the two listened attentively and took notes, asking questions whenever they didn't understand something.

.

After chatting with the Liang sisters, Li Mu adjusted his mood and resumed his alchemy experiments.

The alchemy session lasted the longest that day, starting in the morning and continuing until evening.

Over ten hours, a total of twelve batches were refined. To replenish the insufficient spiritual energy, Li Mu took three Great Qi-Nourishing Pills.

Although all twelve batches of pills were successfully refined, only one batch satisfied Li Mu, producing only three low-grade pills.

The recipe for this batch of pills is as follows: the auxiliary ingredients remain the same, but add five drops of soul essence, two stalks of stick grass, two drops of thousand-year-old stalagmite water, and a small piece of purple coral.

As the day ended, Li Mu felt exhausted, but his mood became extremely excited, and the Liang sisters were also all smiles.

Li Mu did not take the refined pills. After the formula was finalized, he would continue to refine the Rejuvenation Pill to give himself the best.

After two days of rest, he resumed refining elixirs.

To ensure the quality and grade of the pills he produced, he only refined two batches of pills each day.

A week later, twelve Rejuvenation Pills were successfully refined, one of which was of medium grade.

Three days later, his alchemy skills became even more proficient, and the success rate of pills was stable at full, with mid-grade pills accounting for half of his output.

He was confident that he could refine a high-grade pill if he continued, but the essence of his soul liquid was exhausted.

.

Li Mu put away the pills he had refined, said goodbye to the Liang sisters, and returned to his villa with some lingering interest.

Lin Hongluan was scrolling through her phone at home when she noticed that Li Mu seemed a little down, so she quickly got up to check on him.

Faced with Lin Hongluan's concern, Li Mu realized he had been preoccupied with appearances, and immediately put on a smile, revealing a happy expression.

"Haha! Hongluan, I've successfully refined my elixir! Come and congratulate me!"

Lin Hongluan noticed the change in Li Mu's expression; his face, which had just been furrowed brows, suddenly turned into a goofy one, which made her a little uncomfortable.

"You, you're really okay? I just saw you looking really unhappy."

"Hehe! I was just kidding! Let me tell you, I'm really happy right now, I've never been happier than I am now."

And hey, Hongluan, you have to trust your dashing, incredibly capable, and ridiculously handsome husband.

"Tch! You're such a tease! What do you want to eat tonight? Tell me quickly so I can prepare in advance."

Lin Hongluan was a little suspicious that Li Mu had activated his goofy side; this husband seemed a bit unreliable.

Li Mu's goofy demeanor was also a way of trying to quickly adjust Lin Hongluan's mindset.

The successful refining of the elixir should have been a joyous occasion, but a few regrets affected those who cared about him.

This is a situation he doesn't want to see, especially with his loved ones.

Hearing that Lin Hongluan was preparing dinner, Li Mu suggested inviting the Liang sisters over for a meal together.

This is a good suggestion, but it puts Lin Hongluan in a difficult position.

In two months, he learned to make noodles and stir-fry a few home-style dishes. He wanted to invite people to eat her cooking, but she felt guilty.

.

The dinner, which was a treat for guests, ultimately consisted of seven or eight home-style dishes prepared under the direction of Liang Huan, the guest.

Including Cheng Yishi, who happened to arrive at dinner time, the five of them had dinner together.

With the addition of the even more hilarious Cheng Yishi, the atmosphere became very lively, filled with laughter and joy.

Dinner ended amidst laughter and chatter; this simple meal strengthened the bonds between the group.

On the path of spiritual practice, amidst the hustle and bustle of this world, it is truly precious to have such warm feelings between each other.

After dinner, Li Mu returned to his room and took a mid-grade Rejuvenation Pill.

He should have taken the elixir long ago, but he was so engrossed in the mysteries of alchemy that he forgot.

The pills melt upon entering the mouth and, once inside the body, transform into a medicinal liquid that rapidly spreads throughout the body.

A surge of purple energy rapidly merged into the Purple Mansion, and the soul's injuries were quickly nourished by the essence of the soul liquid, instantly healing half of the damage.

Before the effects of the medicine wore off, Li Mu took two more pills, and an even more powerful medicinal effect began to repair and nourish his damaged soul.

Two hours later, the soul injury that had troubled Li Mu for many days was completely healed, and his body and mind were sublimated, making his soul stronger than before he was injured.

Moreover, the purple energy in the elixir entered the Purple Palace, as well as the meridians and dantian.

The purple energy that entered the meridians and dantian actually fused the chaotic energy and spiritual energy into a new kind of spiritual power.

This was a mutation in cultivation, and Li Mu could sense that this mutated spiritual power was incredibly strong.

This was a change that Li Mu had not anticipated, and it could be described as an unexpected surprise.
