Without hesitation, Lu Yu spent 3 million experience points to upgrade the Celestial Spirit Profound Qi Technique to the tenth level, raising his realm to the third layer of the Qi Mastery Realm.

[Through diligent cultivation! The Celestial Spirit Profound Qi Technique has been upgraded to the tenth level, Qi Blood +5, Spiritual Power +150]

[Insight gained from cultivating the Celestial Spirit Profound Qi Technique, realm upgraded to the third layer of the Qi Mastery Realm, Qi Blood +11, Spiritual Power +200]

Then refine and consume 4 Spiritual Qi Fruits.

Each of these 4 Spiritual Qi Fruits contains over ten thousand units of Spiritual Qi, formed from the Spiritual Power cultivation of various life forms devoured by the Undying Demon Flower, concentrating the essence of multiple beings' Spiritual Power.

Using the Purple Flame Demon Fire to burn the soul imprints, mental fragments, and residual consciousness within the Spiritual Qi Fruits, Lu Yu consumed the four Spiritual Qi Fruits and activated the Ice and Fire Sevenfold Heaven Cultivation Technique for some time, refining all the Spiritual Qi.

The four Spiritual Qi Fruits enhanced Lu Yu's Spiritual Power by 2000 points.

Currently, Lu Yu's Qi Blood reaches 2040, total Spiritual Power reaches 7350, with Ice and Fire Spiritual Power respectively at 3675.

The cultivation of Spiritual Power has reached the seventh layer of the Qi Mastery Realm.

Glancing at the sky outside, after refining the four Spiritual Qi Fruits, he unknowingly finds that it's already evening.

After dinner, Lu Yu begins the most important task—refining the Eye of the Sea.

Lu Yu was not planning to give up the power of the Fire Demon Pupil. After researching the refinement method of the Eye of the Sea, he was ninety percent sure he could force all the power of the Fire Demon Pupil in one eye into the other.

The ability of the Eye of the Sea to manipulate the ocean, that is, to control water flow, would not conflict with the Ice Jade Pupil, making it possible to treat the Eye of the Sea as a blank canvas for cultivating the Ice Jade Pupil.

By then, Lu Yu would possess three abilities: controlling fire, controlling water, and controlling ice.

Before actually starting to refine the Eye of the Sea and transfer the power of the Fire Demon Pupil, Lu Yu rehearsed no fewer than ten times in his mind.

The rehearsal process involved the refinement method of the Eye of the Sea and the cultivation technique of the Fire Demon Pupil.

Only after resolving all possible conflicts and contradictions between the two techniques did Lu Yu dare to take action.

The real assurance that allowed Lu Yu to take the risk with his eyes was that he had already found several natural treasures and pills that could be used to restore his eyes, even if an eyeball exploded, he could use those treasures and pills to heal his injured eyes.

As for whether the power of the Fire Demon Pupil could be retained after the eyes healed, Lu Yu wasn't sure, but even if only one eye retained the power, it would be enough.

Lu Yu brought the Eye of the Sea, which seemed to contain a vast ocean, close to his left eye, activating the refinement method to draw out the power within the Eye of the Sea.

Establishing a power bridge between his left eye and the Eye of the Sea, Lu Yu's vision suddenly transformed, seeing himself situated above an endless ocean, with sea water stretching to infinity beneath him.

This sea water symbolized the power of the Eye of the Sea.

The Eye of the Sea is a treasure chosen by the merfolk as a royal token, possessing extraordinarily high quality, surpassing spirit-level natural treasures, containing the power of the ocean, and can only be formed in deep sea eyes.

So far, the merfolk have only mastered seven sea eyes, and each Eye of the Sea takes at least a hundred years to form, so they seldom send the royal token Eye of the Sea to outsiders.

If it weren't for Hai Wei's extremely special status, Hai Yuling wouldn't have given an Eye of the Sea to Lu Yu.

Moreover, the merfolk can sense the power of the Eye of the Sea within a certain range. If Lu Yu approaches the deep sea, they can immediately detect his location.

A human recognized by Hai Wei was worthy of receiving an Eye of the Sea from Hai Yuling.

Under Lu Yu's guidance, the power within the Eye of the Sea entered his left eye, instantly causing him to feel a swelling sensation.

That sensation was as if his left eye was already full, yet Lu Yu continued to "consume" more, and the space in the left eye to contain power was insufficient.

While activating the operation method of the Eye of the Sea, Lu Yu also performed the cultivation technique of the Fire Demon Pupil, directing the power within the left eye of the Fire Demon Pupil into the right eye.

Using the power of the Eye of the Sea to compress the power of the Fire Demon Pupil while opening a passage to the right eye, this was Lu Yu's method of transferring the Fire Demon Pupil's power, fairly violent.

Having practiced the operation of two techniques simultaneously in advance through mental simulations, he only needed to repeat the previous simulated operations.

Although he encountered unforeseen problems not anticipated in the simulations, overall, it was successful.

The power of the Eye of the Sea expelled the power of the Fire Demon Pupil from the left eye. Lu Yu felt the swelling sensation in his left eye diminishing, but the right eye experienced a burning sensation, shedding tears uncontrollably.

Crack! The Eye of the Sea split open, all its power entering Lu Yu's left eye.

Lu Yu felt a bit dizzy. He hadn't anticipated the severe Spiritual Power drain from refining the Eye of the Sea, nearly unable to complete the refinement. Now, overly exhausted, he only wanted to sleep.

The overexertion of Spiritual Power resulted in a heavy feel on his left face.

His eye socket felt unusually heavy.

The right eye was still searing; even when tightly closed, he could see the light of flames through his eyelids.

In the short term, Lu Yu couldn't use his right eye normally, unable to control its power.

Within seconds of lying on the bed, the room was filled with Lu Yu's snoring.

As he slept, his right eye continued to weep, soaking his pillow.

By the latter half of the night, the right eye gradually stopped tearing, and the red light in the room began to dim.

Lu Yu's body was gradually adapting to the newfound power.
