I can gather experience beads

Not long after.

After notifying Yun Changsheng, Yun Tiankong hurried over.

"Senior Cao, I have already informed the ancestor."

"The ancestor agreed, and the payment of 30,000 spirit stones has been settled."

Cao Rui nodded slightly. Through the contract sensing, he knew that Yun Tiankong was not lying.

"Okay, help me find a recipe for refining the second-level Demon Spirit Pill." Cao Rui said.

Yun Tiankong was slightly startled: "The recipe for the second-level demon spirit pill..."

Yun Tiankong patted his storage bag, took out a jade slip, and handed it to Cao Rui.

"I have it here, Senior Cao, please take a look."

You want the recipe for the Demon Spirit Pill, you are here to refine the pill. It seems that these six sea monsters were indeed killed by Senior Cao.

Killing six sea monsters in a short period of time, Senior Cao's strength is unfathomable.

Cao Rui reached out to take the jade slip, slowly injected a trace of magic power into it, and examined it carefully.

Soon, he saw the contents of the jade slip - the recipe given by Yun Tiankong was called "Yunjian Yaoling Pill", which was one of the most widely circulated and most common Yaoling Pill recipes on the market in the East China Sea region.

Cao Rui looked at it carefully, but suddenly found that the so-called Demon Spirit Pill recipe was too simple and not complicated at all! Its difficulty was not even as difficult as some 0-level pill recipes. No wonder almost all foundation-building cultivators could refine the Demon Spirit Pill by themselves!

With his rich knowledge of pharmacology, Cao Rui could discover that the recipe for the so-called Demon Spirit Pill was just to use auxiliary medicines to purify the demon power in the demon pill.

After the demon pill is purified and the chaotic demonic power is smoothed out, it can be absorbed and digested by the cultivator.

During the whole process, a lot of the demon pill's energy will be consumed.

"Are there any other recipes for the Demon Spirit Pill?" Cao Rui asked.

Yun Tiankong replied, "The Yunjian Demon Spirit Pill is the most effective second-level demon spirit pill recipe on the market. It can basically preserve more than 30% of the demon pill power of the second-level demon pill."

"Please collect for me all the recipes for the second-level demon spirit pills on the market in Donghai Market." Cao Rui said.

Although Yun Tiankong did not understand Cao Rui's intention, he did not ask any further questions. He received the order and went to collect the recipes.

With the help of the market owner, Cao Rui soon had eight more recipes for the Demon Spirit Pill.

Cao Rui looked at them one by one and found that it was indeed as Yun Tiankong said. The recipes of these Demon Spirit Pills were similar to the Yunjian Demon Spirit Pills in terms of efficacy, both of which were used to purify demonic power.

And its efficacy is much worse than that of Yunjian Yaoling Pill.

One of the pill recipes can only preserve 10% of the demon pill's power.

However, Cao Rui collected these recipes only for the purpose of gathering information.

It is obviously very difficult to create a recipe for the Demon Spirit Pill from scratch in a short period of time.

However, with Cao Rui's current level of alchemy master, it would not be a problem to collect the recipes of these predecessors, extract their essence and remove their dross.

Cao Rui asked Yun Tiankong for an alchemy room, purchased some elixirs, and began to modify the elixir recipes in the alchemy room with his knowledge of pharmacology.

So. Five days later. In the alchemy room, Cao Rui slowly opened his eyes, a hint of surprise flashed in his eyes. He gently stroked the recipe in his hand and muttered to himself: "The new recipe is ready. It can preserve about 50% of the demon power. The auxiliary materials of the recipe are worth 240 spirit stones, which is not expensive."

After several days of trial and error, Cao Rui finally succeeded in improving the recipe for the second-level demon spirit pill.

The materials needed for this new pill recipe were relatively cheap, which made Cao Rui very satisfied.

Relying on his solid knowledge of pharmacology and alchemy skills, Cao Rui successfully completed the improvement of the elixir formula.

"Let's give it a name." Cao Rui thought for a moment and decided to name the pill recipe "East Sea Demon Spirit Pill".

The name implies that this elixir was developed in the Xiuxian Market in the East China Sea, and also represents his experience here.

Looking at the pill in front of him, Cao Rui's heart was filled with a sense of accomplishment. This was not only a pill, but also the result of his alchemy skills reaching a certain level.

Cao Rui took a deep breath, calmed himself down, and then took out a second-level demon pill from his storage bag. The second-level demon pill was also the core ingredient of his new pill formula.

He carefully held the second-level demon pill in front of him, feeling the powerful energy contained in it.

Next, Cao Rui took out his third-level alchemy furnace.

He lit the flame in the alchemy furnace, adjusted the temperature, and then put the various auxiliary materials into the alchemy furnace one by one.

These auxiliary materials are carefully selected and, when combined with the second-level demon pill, can exert the greatest effect in tempering demon power.

Finally, Cao Rui gently threw the second-level demon pill into the alchemy furnace.

As the demon pill entered the alchemy furnace, a powerful energy wave instantly erupted.

Cao Rui immediately used his spiritual power to stabilize the alchemy furnace to prevent it from exploding.

Under the combined effects of the pill fire and auxiliary materials, the overbearing demonic power on the second-level demon pill was gradually consumed and dissolved, leaving only pure demonic power.

This process requires time and patience, but Cao Rui has always maintained a high level of focus.

Several hours passed, and the dark blue demon pill was still rolling in the alchemy furnace. Its color slowly turned into light blue, and its volume shrank by nearly half.

Cao Rui knew that this meant that he had successfully removed most of the impurities in the demon pill and extracted the pure demonic power.

hum!

Cao Rui extinguished the elixir.

The demon pill at this time is extremely pure and can already be called a demon spirit pill.

"At least 60% of the demonic power has been retained." Cao Rui looked at the demon pill in front of him and was not surprised.

With his alchemy skills, it is not surprising that he can achieve this.

"Let's try and see the effect of this Donghai Elixir."

Cao Rui glanced at the Shenyuan Jue experience beads in his mind, which were currently at the 1% level.

Cao Rui swallowed the Hailing Pill in one gulp.

The rich and pure energy of the Demon Spirit Pill dissolved in Cao Rui's stomach.

Cao Rui activated the experience beads to absorb these energies.

It seemed as if purple water was continuously pouring into the dark black experience bead.

After a full cup of tea, the energy of the Demon Spirit Pill was finally absorbed by the experience beads.

Cao Rui looked at the Shen Yuan Jue experience bead again. "Nineteen percent."

"A demon spirit pill can actually increase so much experience points."

"No wonder Elder Ye said that the happiest time was when we were hunting monsters in the Endless Sea."

"Besides, my demon spirit pills were absorbed with experience beads, so there are no side effects at all..."

No matter how the Demon Spirit Pill is refined, as long as there is energy, there will be chaotic demonic power hidden in it.

After all, it is essentially a demon pill. After tempering, it only reaches the level that can be absorbed by cultivators, and it is far from being 100% pure.

The rest of the cultivators, after taking the elixir, need to spend a lot of time to dissolve the demonic power that has taken the opportunity to invade their magic power. This process can take as little as several months or as long as a year or two.

Cao Rui had no such concern at all. In the process of absorbing the demon spirit pill and converting it into experience points, the experience pill had already eliminated the residual demonic power.
