After entering the space, Nanqu looked at the surrounding environment with a sense of disbelief.

What she had entered was her family's former clinic. Now, she stood in a medicinal herb field, filled with herbs imbued with spiritual energy.

In front of the medicinal herb field, there are five different buildings.

First and foremost, what Nan Qu was most concerned about was the outer gate of their family's clinic, which she hadn't seen since she transmigrated into the martial arts world.

Almost reflexively, Nan Qu arrived at the entrance of the clinic.

With trembling hands, he opened the door to the clinic.

Looking inside, it had transformed back into the old clinic her family used to run. For a moment, Nan Qu seemed to see her father sitting there treating patients and prescribing medicine, while her mother stood in front of the medicine cabinet, constantly dispensing medicine for people.

Nan Qu thought she had grown up and that her memories of her parents were blurred, but now it seems that's not the case.

However, she is strong enough now and will not lose her mind because of missing someone.

Nan Qu looked around and confirmed that this clinic was exactly the same as when she first acquired her spatial ability; the medicinal herbs in the cabinets were still constantly being replenished. However, they were all ordinary herbs. There were no rare or miraculous herbs.

Emerging from the clinic, to the left is a silver-white laboratory. Even without entering, Nanqu knew this must be a pharmaceutical lab. To the left is the mountain where Regal lived.

To the right, there was a strange door. Nan Qu went inside and discovered that it led to the ancient era, the timeline where Bai Ze and his companions lived.

Further to the right, there was a thatched hut. Curious, Nan Qu went inside and discovered a hidden world within. There was a medicine cabinet inside, where Nan Qu found the medicinal herbs she had placed there.

In front of the medicine cabinet was an alchemy furnace. Below the alchemy furnace were horizontal and vertical fire pits.

It seems that this upgrade has divided the previously merged space into different sections.

As expected of a high-level spacetime, even the upgrades are extraordinary.

I've heard Master Baicao say that not everyone has a fire elemental root, and those who don't have one either need to capture heavenly fire or use earthly fire.

The Medicine Sect has a dedicated alchemy room, divided into countless smaller rooms, each isolated by an array. Each room contains earth fire, specifically for disciples who lack heavenly fire or fire spirit roots.

Nan Qu was somewhat curious about the difference between refining pills with earth fire and refining pills with fire spirit roots.

Therefore, the medicinal materials for Peiyuan Dan were prepared.

She just hadn't expected the subterranean fire to be so violent.

At first, Nanqu followed her previous alchemy methods, placing the herbs into the furnace and heating them to transform them. However, now, the herbs burst into flames as soon as she put them in, leaving not even a trace of ash.

Clearly, this earth fire was far more powerful than her spiritual fire.

Nan Qu emerged from the space and found books about refining medicine with earth fire. Only then did she realize that, unlike heavenly fire and fire spirit roots, earth fire is an existence that has a tacit understanding with its master and can control the temperature of the fire.

Earth fire is a naturally occurring source of fire on the earth, and it cannot claim a master. Nature is also a merciless fire.

If you want to refine pills using earth fire, you can't control the temperature yourself like other methods. What you need to do is match the temperature of the earth fire.

This, however, requires control through divine sense.

Refining elixirs with earth fire doesn't involve simply throwing herbs into the furnace. Instead, it involves using divine sense to guide the herbs into the furnace. The herbs are then suspended in the center of the furnace. The heat within the furnace is used to extract the medicinal properties from the herbs.

In other words, if you want to use earth fire to refine pills, your spiritual sense must be strong enough.

Coincidentally, Nan Qu's cultivation level wasn't very high, but her spiritual sense was quite strong. After all, she had traversed three worlds and then used spatial abilities to travel back and forth. Her spiritual sense had surpassed that of a Nascent Soul stage cultivator. Therefore, refining pills using her spiritual sense was truly not complicated for her.

The divine consciousness split into three. One part was placed into the alchemy furnace, and after finding the right temperature, another part began to add medicinal herbs. The third part began to continuously refine the impurities in the medicinal herbs.

The medicinal properties are retained, while impurities are removed.

Then, spiritual energy is input to allow the medicinal herbs to fuse together in sequence. Finally, they are divided equally. Then the pill is complete.

Unexpectedly, while waiting for the results, a bright light suddenly emanated from the alchemy furnace. Then, the lid of the furnace was opened, and pills flew out one by one.

Nan Qu subconsciously used her divine sense to imprison each pill. Then she opened the medicine bottle. Soon, the pills were placed into the bottle.

After everything calmed down, Nanqu opened the medicine bottle.

She had never encountered a situation like this before, and was unsure whether the Qi-Nourishing Pill had been successfully refined.

Unexpectedly, when she opened the medicine bottle, she smelled a particularly refreshing scent that completely soothed her, who was feeling quite hot standing in front of the fire.

Nan Qu poured a pill into her hand, only to find that the pill she had refined was different from the one Bai Cao had given her.

If I had to pinpoint the difference, it would be that the patterns on the pills given by Master Baicao weren't as clear as hers.

The Peiyuan Pill given by Master Baicao has a grayish-black pattern, making it very difficult to see on the pill itself.

Hers is silver. It's very eye-catching.

Nan Qu wasn't sure if the pills she had refined were of good quality. She also dared not let Bai Cao see them. Bai Cao was so skilled; what if she could tell that she had used earth fire to refine them? How would she explain where the earth fire came from? And how would she explain how a Qi Refining Stage 5 cultivator could refine pills using divine sense?

There's simply no way to explain it.

If she couldn't explain it, she would find the answer herself.

Fortunately, the answer was in the library. Looking at the book's description of Nanqu, I learned that elixirs are also graded: low-grade, medium-grade, high-grade, spiritual-grade, holy-grade, and divine-grade.

The clearer the patterns, the higher the quality. Silver patterns like those on the Nanqu jade are considered spiritual quality. Above that are white holy quality and golden divine quality.

Seeing this, Nan Qu was overjoyed; she had successfully refined a Spirit-grade Qi-Nourishing Pill on her very first attempt. This showed that she truly possessed great talent.

With the Peiyuan Pill, Nanqu was eager to go back.

She's been in this world for over two months now. She's starting to miss her husband and children.

So, after buying some fasting pills, Nanqu decided to go into seclusion to cultivate.

Back in the modern world, Nan Qu was a little disoriented for a moment. But she quickly recovered.

Nan Qu had no intention of bringing cultivation techniques from the cultivation world to this world. Having internal energy in this world was already incredibly powerful. Even if she did bring cultivation, she wasn't sure if it would have any impact on this world.

Even the Time-Space Beast couldn't guarantee this.

Back in her small villa in Northeast China, Nan Qu hadn't yet seen her children or husband. But she felt a sense of belonging. Knowing that Su Ruoyan had gone skiing with the children, Nan Qu simply sat in the living room and turned on the TV.

Su Ruoyan and the children returned at three o'clock in the afternoon. After returning, the two children excitedly told Nan Qu about their performance that day.

Su Ruoyan stood to the side and teased, "You skipped it today. Next time you go, you'll probably be worse than two kids."

The two children perked up immediately: "Mom, let's go skiing again tomorrow! I'll be your instructor!"

"Then I'll be the assistant coach."
