Lu Supervisor furrowed his brows almost imperceptibly upon hearing Han Li's words, but quickly regained his composure.

"Manager Lu can rest assured that all expenses for the contest will be borne by me," Han Li added.

"Since Senior has said so, our Thousand Medicines Hall will naturally not refuse Senior's interest, please." Lu Supervisor said without further hesitation upon hearing this.

With that, he took the lead, walked out of the room, led Han Li downstairs, exited from the main hall on the first floor, and walked along a winding corridor towards the backyard.

Deep in the backyard was a circular archway that separated the front yard.

Before even reaching the archway, Han Li sensed a layer of transparent light screen floating in the void within the gate, from which came distinct spatial fluctuations, indicating that it was a teleportation formation.

Reaching closer, Lu Supervisor stopped and turned to Han Li, saying, "Senior, please wait here for a moment. I will inform them first."

Having said that, he flipped his hand and took out a purple token, waving it in the void towards the archway. Immediately, a bright light lit up within the gate.

He took a large step and walked into the gate, his figure disappearing immediately.

After observing the surrounding environment for a moment, Han Li saw the light within the gate rise again, and at the same time, Lu Supervisor's voice came from within:

"Senior, please come in."

Upon hearing this, Han Li stepped into the gate.

As soon as he entered, he felt a heat all over his body, and a rich and mixed medicinal scent reached his nose.

After looking around, he realized that they seemed to be in a hall similar to an underground palace, with several wide lanes leading in all directions.

On the walls on both sides of the lanes were bronze doors, each about ten feet high, with faint lights shining from within.

Before Han Li could clearly see the surrounding environment, Lu Supervisor led him into one of the lanes, arriving at a spacious reception room.

Sitting inside the reception room was a red-haired old man of medium build, wearing a purple-black short shirt, holding a teacup in one hand and using the lid to skim the tea leaves with the other.

Han Li scanned him at a glance and found that the man's aura was profound, making him clearly a Mahayana cultivator.

Seeing the two enter, the red-haired old man put down his teacup and slowly stood up.

Lu Supervisor, seeing this, introduced to Han Li:

"Senior, this is Grandmaster Zhu of our Thousand Medicines Hall, a Grade A Alchemist of the Human Rank. He has agreed to help you with this test."

"Then thank you very much, Grandmaster Zhu." Han Li said, bowing to him upon hearing this.

Knowing that Han Li's cultivation aura was no weaker than his, the red-haired old man did not dare to be negligent, and returned the greeting slightly, saying:

"Since Fellow Daoist wants to test his Alchemy level, then let us each refine a Huayang Pill to restore mana. By comparing the quality of the pills, we can determine Fellow Daoist's level."

"Huayang Pill? I don't yet know the composition of this pill formula. I wonder if your Hall can sell it?" Han Li frowned slightly and asked.

"Oh?"

The red-haired old man was slightly surprised upon hearing this, seemingly not expecting Han Li to not even know this pill, and couldn't help but look down on him a bit in his heart.

"There's no need to buy it. Although the Huayang Pill is of a rather high grade among Human Rank pills, its formula is quite widespread in the nearby sea area, and it can be obtained in many places. It's not worth much money, so I'll give it to you."

After saying that, the red-haired old man flicked his wrist, and a white jade slip floated lightly to Han Li.

Han Li took it and scanned it with his divine sense, and couldn't help but sigh in his heart.

The pill formula was free, but the medicinal materials used in this formula were all expensive items, and he had to pay money to buy two portions, which was indeed a considerable expense.

After that, the red-haired old man began to explain to him, in a lukewarm manner, some of the precautions for refining the Huayang Pill.

While listening carefully, Han Li nodded slightly, silently memorizing everything, and at the same time, he began to deduce the steps for adding the spiritual herbs and the control of the fire, based on his past experience.

Half an hour later, the two took the storage bags, already prepared and containing the spiritual herbs needed to refine the Huayang Pill, from Lu Supervisor, and each walked into an alchemy room.

With a "clang", the heavy bronze door closed.

Han Li looked around the room and found that the alchemy room here was indeed somewhat different from what he had seen in the Spirit World.

There was almost no furniture in the room, only a one-person-high purple bronze alchemy furnace placed in the center. There was no fire pit on the ground, and no fire-inducing runes on the furnace body.

The surrounding walls and the ground were engraved with complex runes, which seemed to be some kind of restriction that could condense and lock the spiritual energy in the room.

He only looked at it for a moment before calming his mind and preparing to start refining pills.

He raised his palm and snapped his fingers with a "snap", and a silver-white flame flew into the pill furnace like a bird.

With a "whoosh",

Burning silver flames rose in the pill furnace.

After about the time it takes to drink a cup of tea, after the temperature inside the pill furnace rose high enough, Han Li began to add the spiritual herbs into the pill furnace one by one.

As one spiritual herb after another flew into the furnace, a strange medicinal fragrance began to permeate the entire alchemy room.

After about an hour, Han Li heard a "poof" sound from inside the pill furnace, and saw a wisp of light purple mist rising from the gap at the top of the pill furnace, gathering above the pill furnace, condensing and not dispersing, which was very peculiar.

According to what the red-haired old man had said before, it was time to add the Huayun Grass at this time.

But when Han Li took the pale white spiritual grass in his hand, he hesitated a little.

From the Mortal World to the Spirit World, he had refined countless pills. All the combinations of spiritual herbs and materials could be summarized as "King, Minister, Assistant, Envoy". Among them, the King was the main herb, the Minister was the auxiliary herb, the Assistant was the second-class auxiliary herb, and the Envoy was the harmonizing herb.

This Huayun Grass was not a unique spiritual herb of the Immortal World. He had used it in the Spirit World before, and knew that this herb had a mild medicinal property and was often used as an envoy herb to harmonize the medicinal properties of various herbs. Naturally, it was no exception in this Huayang Pill.

At this time, the purple mist had just risen in the pill furnace, indicating that the medicinal properties of the previous herbs had just begun to emanate and had not yet reached the time when they needed to be harmonized. Adding the Huayun Grass at this time was definitely not the best time, so he hesitated.

But soon, he made a decision and stuck to his own opinion.

After another half an hour, when the purple mist in the pill furnace turned from light to thick, Han Li immediately lifted the furnace cover and added the Huayun Grass into it.

As a burst of rich medicinal fragrance rushed to his nose, a trace of joy appeared in Han Li's eyes.

At this time, lights suddenly lit up on the surrounding walls, and the array patterns engraved on them actually began to operate on their own.

A small vortex was immediately formed in the entire alchemy room, wrapping the spiritual power escaping from the pill and gathering towards the pill furnace.

……

Two hours later, the red-haired old man had walked out of the alchemy room and was standing with Lu Supervisor, waiting outside Han Li's alchemy room.

After about a quarter of an hour, the bronze door on Han Li's side also slowly opened, and he walked out holding a white porcelain bottle in his hand.

Lu Supervisor smiled upon seeing this:

"It seems that Senior has also successfully refined the pill. Congratulations, congratulations."

"I don't yet know what the grade is. Please, Manager Lu and Grandmaster Zhu, appraise it." Han Li said, handing over the porcelain bottle.

Lu Supervisor took it and pulled out the stopper, and a rich medicinal fragrance immediately escaped from it.

The red-haired old man's expression suddenly changed slightly after smelling it, and he couldn't help but move closer to Lu Supervisor, looking at the pill refined by Han Li.

At this time, in Lu Supervisor's left and right hands, were placed the three Huayang Pills refined by each of them. The appearance did not seem to be much different, but Han Li's pill seemed to be smaller.

Han Li turned his gaze to the red-haired old man, intending to ask a question, when he saw him sigh silently and turn away directly.

Seeing this, Lu Supervisor did not stop him. After his figure disappeared at the end of the lane, he said to Han Li with a slightly strange expression:

"Senior, don't blame him. This Grandmaster Zhu is... is a little shocked."

Upon hearing this, Han Li already understood what he meant, and waved his hand with a smile, saying, "Then please, Manager Lu, appraise it."

"If, as Senior said earlier, you have not been exposed to high-level Immortal World pills before, then Senior is truly a talent in the art of alchemy. Senior's control of the heat is truly extremely precise, able to remove all the impurities from these three Huayang Pills without harming the medicinal power at all... The quality of these pills is even higher than those refined by Grandmaster Zhu." Although Lu Supervisor was not good at refining pills, he seemed to have some research on the art of pills, and he spoke eloquently.

"Then, based on this, what level should I be in the Immortal World alchemist?" Han Li asked with a slight smile.

"Although only the Huayang Pill has been refined, judging from the quality of this pill, Senior is already a Grade A Alchemist of the Human Rank." Lu Supervisor said solemnly.

Han Li nodded thoughtfully after hearing this.

In fact, refining pills of this grade, although he has not yet exerted his full level, the complexity and difficulty of refining this pill is no less than those top-level pills in the Spirit World.

If calculated according to this, his alchemy skills, which he was once proud of, are probably only equivalent to a Grade C Alchemist of the Earth Rank in the Immortal World.

"In fact, with Senior's current alchemy skills, you may be able to become a Earth Rank alchemist in the future." Seeing that Han Li did not show any excitement, Lu Supervisor's heart moved, and he said with a slightly flattering tone.

"Haha, then I'll take Lu Daoist's kind words." Han Li responded in his mouth, and immediately made a decision in his heart.

He must become a Celestial Alchemist in the future, so that as long as he finds a suitable Dao Pill formula, he can refine the mysterious crystal grains produced by the small bottle into Dao Pills.

After all, the Law spiritual materials that are extremely precious to others are much easier for him to obtain.

"I wonder if Senior plans to stay in this Black Wind City for a long time, or is just staying temporarily?" Lu Supervisor hesitated slightly and asked.

Han Li frowned slightly upon hearing this.

Seeing this, Lu Supervisor quickly explained:

"Senior, don't misunderstand. I just want to invite Senior to join our Thousand Medicines Hall and be an enshrined alchemist. I believe that with Senior's alchemy level, you will definitely soon become a high-level enshrinement second only to Grandmaster Hao, at that time..."

Han Li waved his hand, interrupting his words, and said, "I am only staying here temporarily and will not stay for long. I can only accept Daoist's kindness in my heart."

Seeing that his expression did not seem to be false, Lu Supervisor had no choice but to sigh a few times in regret and let it go.

After that, Han Li bought some Wangyuan Pills, and settled the cost of refining the Huayang Pill together, and then left without staying any longer, bidding farewell.

Of course, the six Huayang Pills refined by him and the red-haired old man were naturally all collected by him and taken away together.
