Chapter 159 East Sea Demon Spirit Pill

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, and through the contract induction, he could know that Yun Tiantian was not lying.

"Okay, you can help me find a recipe for refining the second-level demon spirit pill." Cao Rui said.

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

Yun Tiantian patted the storage bag, took out a jade slip, and presented it to Cao Rui.

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

The recipe for the Demon Spirit Pill must be refined to refine the elixir. It seems that these six sea monsters were indeed killed by Senior Cao.

Killing six sea monsters in a short period of time showed that Senior Cao's strength was unfathomable.

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

Soon, he saw the contents of the jade slip - the elixir given by Yun Tiankong was called "Yunjian Demon Spirit Pill". It was the most widely circulated and most common demon spirit elixir prescription on the market in the East China Sea region. one.

Cao Rui looked over carefully and found out to his surprise that this so-called demon spirit elixir recipe was too simple and had no complexity at all! Its difficulty is not even comparable to some level 0 pill recipes. No wonder almost all foundation-building monks can refine the demon spirit pill on their own!

With his rich pharmacological knowledge, Cao Rui could discover that the so-called demon spirit elixir recipe only uses auxiliary drugs to purify the demon power in the demon elixir.

After the demon elixir is purified and the chaotic demon power is smoothed out, it can be absorbed and digested by the monks.

The whole process should consume a lot of demon elixir energy.

"Are there any other demon spirit elixir prescriptions?" Cao Rui asked aloud.

Yun Tiankang opened his mouth and replied: "Yunjian Demon Spirit Pill is currently the most effective second-level demon spirit pill prescription on the market. It can basically preserve more than 30% of the demon power of the second-order demon pill."

"Help me collect all the second-level demon spirit elixir recipes on the market in Donghaifang City and give them to me." Cao Rui said.

Although Yun Tiankong didn't understand Cao Rui's intention, he didn't ask any more questions and went to collect the elixirs after receiving the order.

With the help of the master of Fangshi, Cao Rui soon had eight more demon spirit elixir recipes in hand.

Cao Rui looked at them one by one and found that indeed, as Yun Tiankong said, the prescriptions of these Demon Spirit Pills were similar to those of Yunjian Demon Spirit Pill. They both purified the demon power.

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

One of the elixir recipes can only preserve about 10% of the demon power of the demon elixir.

However, Cao Rui collected these prescriptions just to collect information.

In a short period of time, it is obviously very difficult to create a demon spirit elixir recipe from scratch.

But by gathering the elixir prescriptions of these predecessors and discarding the dross, it would be no problem for Cao Rui's current level of alchemy master.

Cao Rui asked Yun Tiantian for an alchemy room, purchased some elixirs, and began to transform the elixir recipe in the alchemy room with his own pharmacological knowledge.

in this way. Five days later. In the alchemy room, Cao Rui slowly opened his eyes, with a hint of surprise flashing in his eyes. He gently touched the elixir in his hand and murmured to himself: "The new elixir is ready, and it can preserve about 50% of the demon power. The elixir's auxiliary ingredients are worth two hundred and forty spirit stones, which is not expensive."

After several days of trying and adjusting, Cao Rui finally succeeded in improving the second-level demon spirit elixir recipe.

The price of the materials required for this new recipe is relatively low, which makes Cao Rui very satisfied.

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

"Give it a name." Cao Rui thought for a moment and decided to name this elixir "East Sea Demon Spirit Pill".

The name means that this elixir was researched in Xiuxianfang City, Donghai, and also represents his experience here.

Looking at the elixir in front of him, Cao Rui felt a sense of accomplishment. This was not only an elixir, but also the result of his alchemy skills reaching a certain level.

Cao Rui took a slight breath, stabilized his mind, and then took out a second-level demon pill from his storage bag. The second-level demon elixir is also the core ingredient of his new elixir recipe.

He carefully held the second-level demon elixir 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 heat, and then put various auxiliary materials into the alchemy furnace one by one.

These auxiliary materials have been carefully selected, and when combined with the second-level demon elixir, they 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 burst out instantly.

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

Under the combined action of the elixir fire and auxiliary materials, the domineering demonic power on the second-level demonic elixir was gradually consumed and dissolved, leaving only the pure demonic power.

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

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 pure demon power.

Buzz!

Cao Rui extinguished the elixir.

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

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

With his alchemy skills, it is not surprising to achieve this step.

"Try it out and see the effect of this Donghai Lingdan."

Cao Rui glanced at the Shenyuan Jue experience bead in his mind, which is currently at the level of 1%.

Cao Rui swallowed the Hailing Pill in one gulp.

The rich and pure energy of the demon pill melted in Cao Rui's stomach.

Cao Rui urged the experience bead to absorb this energy.

It seemed that there was a purple stream of water constantly pouring into the dark black experience bead.

After a full cup of tea, the energy of the demon pill was finally absorbed by the experience bead.

Cao Rui looked at the Shenyuan 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 hunting demons in the Endless Sea."

"Besides, my demon spirit pill was absorbed by the experience bead, and there is no sequelae at all..."

No matter how the demon spirit pill is tempered, as long as there is energy, there will be messy demon power hidden in it.

After all, it is essentially a demon pill. After tempering, it only reaches the point where cultivators can absorb it, and it is far from 100% pure.

Other cultivators, after taking the pill, need to spend a lot of time to dissolve the demon power that took the opportunity to invade the mana in their bodies. This process takes at least several months and at most one or two years.

Cao Rui has no such concerns at all. The experience pill has eliminated the residual demon power in the process of absorbing the demon spirit pill and converting it into experience points.
