The quality of the human spirit essence refined by the blood of Zao Xuan Zhenren can be imagined. Even if it is not as good as the heavenly essence, it can still be top-notch among the earthly essences.

Although these three drops of human spirit essence are a little less, they are a quality that Han Xi has never obtained.

Therefore, looking at the dazzling and smooth human spirit floating on his palm, Han Xi's evil and handsome face couldn't help but curl up the corners of his mouth: "Good luck."

Collect three drops of human spirit essence.

Han Xi looked up at the snow around him again.

Since the mysterious blood can be found here, it proves that it cannot be the only place.

But its aura was covered by the white snow, making it difficult for ordinary people to detect it.

Of course, Han Xi couldn't just give up there, so he followed the bloodstain as the center and searched nearby.

As the snowflakes were blown up into the sky, Han Xi actually found a lot of blood residues emitting a mysterious aura, which naturally had to be refined.

While Han Xi was busy refining the essence of the human spirit.

In the quiet room, Kong Ju, who had just exchanged two ancient pill recipes, "Shengyang Pill" and "Shenggu Huanrou Pill", and the immortal technique "Dongyou Zhuyuan", also opened his eyes.

The three jade slips and several spiritual medicines obtained from Lingxiao's treasure house also withdrew from the void of the Enlightenment Monument along with his consciousness and appeared out of thin air in his hands.

"Don't rush to refine the elixir. Take a look at this immortal eye technique first." Kong Ju first put away the elixir formula and elixir, and then impatiently put his consciousness into the "Dongyou Zhuyuan" immortal eye technique jade slip.

Half a day later, Kong Ju finally lost consciousness, with a thoughtful look in his eyes.

This "Dongseuizhuzhuyuan" is worthy of the name of immortal technique.

Its magic is somewhat shocking.

According to the jade slips of immortal arts, when one cultivates to the realm of great success, one can actually see through the barriers of space. Wherever one's sight reaches, the blessed space, reality, and the void are all visible before one's eyes.

"If you are in the void, you can overlook the world; if you are in the world, you can also overlook the void."

Kong Ju was amazed by this. In comparison, the pupil technique of perceiving the cultivation level of cultivators and finding spiritual objects seemed a little shabby.

These are easy for Dong Youzhuyuan who is practicing.

In addition, Dongyou Zhuyuan is not just as simple as the pupil technique.

Since it can be included in the immortal techniques, it naturally has corresponding Taoist techniques.

A pair of strange eyes similar to Liu Che's, which can display powerful magical powers.

The entire "Dongyou Zhuyuan" immortal method is divided into "Dongyou Chapter" and "Eclipse Yin Chapter"

"Dongyou Pian" is a fairy method for cultivating the eyes, which enables the practitioner's eyes to see through all false barriers in the world, even space barriers.

"Eclipse of Yin" is a chapter on Taoist magic.

Guide the practitioner on how to use those dark eyes and unleash the power of magic to fight the enemy.

"No wonder only the lower half is left. The Lingxiao Treasury requires more than a hundred sacrificial points to exchange."

"It's a pity that only the "Dongyou Zhuyuan" chapter is left of "Dongyou Zhuyuan". The "Xiuyin" chapter has been erased when the jade slip was broken."

"That's right. If it's a complete Immortal Eye Technique, how can I exchange it with my limited sacrifice points?"

Kong Ju secretly felt regretful, as he didn't know whether the Enlightenment Stele could complete "The Deep Cave and the Far Away Candle".

Of course, the good news is that although "Dongyou Zhuyuan" is only half complete, the "Dongyou Chapter" for practicing pupil techniques is still complete.

Kong Ju's original intention in learning this magic technique was not to fight against the enemy.

Thinking of this, Kong Ju collected his thoughts and began to ponder the section in "Dongyou" about practicing pupil techniques.

The Dongyou chapter divides the training of pupil techniques into three stages.

The first stage is small.

The second stage is observing the world.

The third stage is the secluded cave.

According to the statement in "The Deep Cave and the Faraway Candle".

As long as the first stage of Zhuwei is cultivated to perfection, no cultivator below the level of immortals will be able to block the cultivator's eyes.

Any false illusions will be exposed, pointing directly to the essence and overlooking the world.

Moreover, the three stages of Zhuwei, Guanshi and Dongyou respectively correspond to three kinds of Taoist magic techniques that can be used to fight against the enemy. Of course, those are all recorded in "Zhu Yin Pian" and are incomplete.

Practicing immortal arts requires immortal fate, and "Dongyou Zhuyuan" is no exception.

There is a prerequisite for practicing pupil techniques in the Dongyou chapter, which is to use natural treasures to nourish the eyes of the soul.

The Dongyou chapter specifically records an ancient pill recipe called "Jianmingye", which is of third grade quality.

Practitioners need to drip the seeing liquid into their soul and eyes, and repeat this process over and over again to warm and nourish them continuously for up to a year.

During this year, the practitioner's soul and eyes will be burning like fire, and he will suffer from the pain of burning flames every day.

After a year, if the practitioner's soul and eyes have not yet produced "candlelight".

It is equivalent to declaring that the practitioner is not suitable for practicing this immortal method.

Forcing yourself to practice carries the risk of harming your soul.

In addition, "Zhu Yin Pian" also records another method that is specially marked.

"For those who are born with double pupils that are nourished by spiritual energy and transformed into spiritual pupils, they can directly skip the step of using the "Jianming Liquid" to warm them up."

"Spiritual pupil!" Kong Ju's eyes suddenly became strange.

Aren’t Liu Che’s pair of strange eyes the result of natural spiritual eyes nurtured by spiritual energy?

"Isn't this a coincidence?" Kong Ju flipped his hand and took Liu Che's other heterochromatic eye in his hand.

"The Cave is Deep and the Candle is Far Away" also said.

Those who are born with spiritual pupils will achieve twice the result with half the effort when practicing this magic technique.

"It's simply a magic method tailor-made for people like Liu Che who are born with heterochromia." Kong Ju exclaimed.

It's a pity that Liu Che did not have such an immortal fate. He was killed by Dapeng in Chaodi Ancient City, and his pair of spiritual eyes ended up becoming a wedding dress for Kong Ju.

But for someone who has reached the realm of palm life, a powerful being that has transcended the physical body, it is already a piece of cake.

This is especially true for a third-grade alchemist like Kong Ju.

"Among the second-grade elixirs, there is a kind of elixir called 'Bone Removal Pill'. After taking it, even the bones in your body can be replaced with others at will."

"Just a pair of eyes, isn't it easy?"

Kong Ju murmured.

"Bone-Cutting Pill" is not a rare elixir, and its medicinal properties and pharmacology are not difficult to understand.

Kong Ju didn't even need to look for a pill recipe deliberately. With his status as a third-grade alchemist, he could make a pill recipe similar to the "Bone-Picking Pill".

"It's just a pair of shields. With great power in the palm, the body can be discarded, let alone a pair of eyes."

"I have mastered this Immortal Eye Technique."

There is no wrong version in the 1619 book forum!

Tightening the pupil in his hand, Kong Ju made the decision without any hesitation.

For many alchemists with good skills in alchemy, as long as they understand the medicinal properties and pharmacology of the elixir, they can prepare many elixirs by themselves without even a prescription.

Of course, to be considered "outstanding", one must be an alchemist of the third rank or above.

Most of the pill recipes prepared are of first grade.

The second-grade elixir is somewhat difficult to make, unless the pharmacology behind it is not difficult and you can find an elixir that can replace it.

The third grade is even more difficult. The pharmacology and medicinal properties of the third grade elixir and the spiritual conflicts of the elixir itself make it extremely difficult to control the medicinal properties ratio and process.

It just so happens that Kong Ju is a third-grade alchemist, and one of the best among them.

After he searched through his collection of spiritual medicines, it only took him an incense stick of time to come up with a substitute for the Bone-Eliminating Pill.

A day later, a furnace of elixirs with similar medicinal properties to the Bone-Picking Pill was produced from the Xuanwu furnace.

As the lid of the basalt furnace opened, a shiny blue-black pill appeared in front of Kong Jue.

He took out the pill which was still warm, and carefully examined it in his hand.

His nose also kept sniffing the medicinal properties of the pill.

After a cup of tea, he was certain that this pill would have similar effects to the Bone-Picking Pill.

After refining elixirs for more than ten years, Kong Ju still has some skills.

"Let's call it... "Returning Pupil Pill." Kong Ju happily named the pill.

Then he swallowed it without any hesitation.

After doing all this, he suddenly raised his left hand and inserted it into his left eye.

Phew!

A chilling sound was heard afterwards.

Kong Ju dug out his left eye expressionlessly, leaving only an empty bloody hole in his left eye socket.

Fortunately, he had already blocked the blood vessels and pain sensation in his eyes in advance, so when he dug out his eyes, not only did he not feel any pain, but there wasn't even much blood.

Then Kong Ju stuffed Liu Che's remaining pupil into the empty eye socket.

The medicinal effect of the Returning Pupil Pill began to take effect.

As the medicinal power flowed in his left eye, the severed blood vessels in his eye socket began to grow wildly, and the freshly grown blood vessels perfectly wrapped the heterochromatic eye.

This process lasted for about an incense stick of time.

Liu Che's strange eye gradually changed from a crystal clear shape to a distinct black and white eye.

Kong Ju tried to close his right eye, and his left eye, which had been replaced with an alien pupil, could see clearly.

Moreover, he could see more clearly with his previous eye. He did not need to use any pupil techniques. He could see the flow of spiritual energy in the quiet room and even the spiritual light on the basalt furnace that was invisible to the naked eye.

Even if Kong Ju did not practice any pupil techniques, this pair of strange eyes could still glimpse many mystical things.

Kong Ju looked at it and blamed himself, "I miscalculated. I should have changed it before. With this pair of eyes, even if I don't have the ability to see through the darkness, practicing any eye technique would be icing on the cake."

Moreover, the pupil technique contained in that strange eye can also be mobilized by Kong Ju at will.

Kong Ju's mind turned, and he poured the power of his soul into that left eye.

Bang! A black and red light that made people feel terrified instantly burst out from his left eye.

It hit the stone wall of the quiet room directly.

Boom! The light with evil light left a huge dent in the stone wall that could defend against the palm-born mighty's attack.

Obviously, Liu Che's pupil technique, when performed by Kong Ju, who was already a powerful palm master, was many times more powerful than Liu Che's at that time.

"But it is not as good as divine power. It can only be regarded as a Taoist skill at the level of a palm-born."

Kong Ju evaluated the power of the pupil technique in that eye and spread his hands.

"It's better than nothing."

Of course, Kong Jue got these strange eyes not for the pupil technique in them.

Touching his left eye socket, Kong Ju smiled slightly and once again focused his consciousness on the half of the "Dongyou Zhuyuan" magic in his hand.

With this strange eye, he not only saved a year of waiting, but could also directly start practicing this immortal eye technique.

At the same time, he can achieve twice the result with half the effort in practicing this pupil technique.

But after replacing Liu Che's heterochromatic eye, Kong Ju's left eye also became a vertical pupil.

Occasionally, a demonic light flashes like that of a demon.

That would have been fine, but his other right eye remained the same as before.

It gives people a weirder feeling than having both eyes have heterochromia. (End of this chapter)
