Thinking of this, Zhou Xun patted the Blood Demon Bag at his waist,

Five beams of blood light flew out and landed in front of Zhou Xun.

"Roar! Roar!"

Looking at the two Blood Demon Crystals in Zhou Xun’s hand, the five Blood Demon Children stirred, each showing a greedy expression, full of desire.

These five Blood Demon Children,

were respectively refined from the corpses of Master Fengyue and Wu Zongdao at the Early-Stage Core Formation; the Celestial Feather Sect Third Elder and the Spirit Control Sect cultivator Feng Yue at the Middle-Stage Core Formation; and the Celestial Feather Sect Grand Elder at the Late-Stage Core Formation,

Master Fengyue and Wu Zongdao were originally newly advanced Core Formation Cultivators, their cultivation was weak,

and the Blood Demon Children refined from their corpses naturally had lower strength levels, barely reaching Tier Three,

and always maintained the lowest standard among the five Blood Demon Children, thus being a major factor influencing their power,

Now with two Blood Demon Crystals here, they could be enhanced,

This way, the combined strength of the five Blood Demon Children could surely increase again.

Therefore, he tossed the two Blood Demon Crystals toward the Blood Demon Children refined from Master Fengyue and Wu Zongdao,

The two Blood Demon Children opened their mouths and swallowed them, expressing satisfaction.

As for the other three, they watched Zhou Xun eagerly,

"Why the rush? Once I have extracted these four Blood Demon Children, there will be plenty for you all!"

Saying this, he waved his hand and directly recalled the five Blood Demon Children into the Blood Demon Bag.

Then he sat cross-legged, took out the Ancient Jade Talisman, and began to comprehend the technique of extracting Blood Demon Crystals within,

This spell was extremely simple, and in less than half an hour, Zhou Xun fully understood it.

So he then took a Blood Demon Bag, gently tapped it, releasing the Blood Demon Child inside,

With its master fallen, as an External Incarnation, it was merely a shell at this point; the once unparalleled, fiercely powerful Blood Demon Child naturally turned sluggish,

This saved Zhou Xun a lot of effort in extracting the Blood Demon Crystals.

With a wave of his hand, the Blood Demon Child in front of him floated up instantly,

Then he formed a spell with his hands, casting a Spirit Light upon the Blood Demon Child, enveloping it in a faint red glow,

Seeing this, Zhou Xun forced out a drop of Essence Blood and, under the spell’s control, transformed it into a Blood Talisman, suspended above the Blood Demon Child,

The spell then changed again, continuously impacting the Blood Talisman and Blood Demon Child,

Afterward, strands of strange blood-red power emanated from the Blood Demon Child, captured by the Blood Talisman above, merging into one.

As time went on, the momentum of the Blood Demon Child diminished, while the Blood Talisman above began to condense into a small bloody stone, and continued to grow larger.

Eventually, this Blood Demon Child became withered and collapsed like a heap of scattered sand, turning into dust,

While above it was an egg-sized, blood-red, gem-like Blood Demon Crystal.

Using the same method, Zhou Xun repeated this process three more times,

Finally obtaining three egg-sized and one fist-sized Blood Demon Crystal.

Zhou Xun then summoned the other three Blood Demon Children, giving each one a Blood Demon Crystal,

It is worth mentioning that Zhou Xun specifically gave the largest one to the Blood Demon Child refined from the Celestial Feather Sect Grand Elder,

It was already at the Tier Three Middle-Grade Level, and after consuming the largest Blood Demon Crystal, to see if it could directly break through to a High-Grade, reaching the late-stage level!

After all this, Zhou Xun absorbed all the Yin Qi from the four Blood Demon Bags into his Blood Demon Bag, greatly replenishing it.

"Once they have completely absorbed and refined the Blood Demon Crystals, who knows what level they will reach, and how much their combat strength will increase!"

After dealing with the Blood Demon Crystals, Zhou Xun meditated for half an hour,

Then he took out the pair of Thunder Eagle Wings he had collected earlier, according to the records in the Thunder Night True Technique,

The best time to refine Thunderbolt Wings was within three days of acquiring the wings of a Thunder Attribute Demon Beast,

This way, the original power could be preserved to the greatest extent; otherwise, with time, the Spiritual Power in the wings would dissipate too much,

The speed of the final refined Thunderbolt Wings would likely be significantly reduced!

Zhou Xun decided to immediately begin the sacrificial refining of the "Thunderbolt Wings," aiming only for an initial refinement to lock in the Spiritual Power and prevent its loss,

After all, in this Secret Realm, treasure hunting was still the main focus.

He examined the giant pair of wings before him, which had been cut down less than a day ago and remained extremely fresh.

Using the method recorded in the Purple Sky True Technique, Zhou Xun forced out a drop of Essence Blood, and then according to the spell, transformed it into a Blood Talisman, embedding it into the wings,

Perhaps due to the Demon Soul of the Thunder Eagle being entirely absorbed by the Cyan Ape, Zhou Xun proceeded very smoothly in this step,

With a successful insertion of a Blood Talisman, Zhou Xun immediately sensed an extremely subtle connection inside,

Seeing this, Zhou Xun was pleased and continued without pause, embedding the next one,

He continued embedding until forty-nine Blood Talismans were successfully inserted, at which point he stopped,

According to the spell’s record, the method he used was called the Blood Refining Technique for refining magical treasures,

The advantage of this method is its simplicity and ease of use, and the refined magical treasures can be stored within the cultivator’s body like Lifebound Magical Treasures, making them extremely handy to control,

The drawback is that the refined magical treasures can basically only be used by the one who refined them,

They cannot be passed down,

Once the refiner perishes, the treasure will lose its Spirituality, with remaining power less than thirty percent!

With the successful insertion of Blood Talismans, the next step was refinement,

Zhou Xun reached out, and the wings floated up,

Then Zhou Xun spread his Divine Sense, wrapping around this pair of giant wings, and continuously cast spells,

Under the refining of these two forces, the giant wings began to change,

Rune after rune was engraved upon them, becoming radiant and full of Spirit,

The connection between Zhou Xun and the wings also grew deeper...

One day later,

"Whew!"

The wings suddenly flashed with light, becoming lively, and Zhou Xun felt a blood-bonded connection with them,

Suddenly, with a thought, the wings flapped once, and with another thought, they flapped again!

"Hahaha, in one day, I’ve finally preliminarily refined these ’Thunderbolt Wings’!"

Zhou Xun was overjoyed!

Although it was only a preliminary refinement at this time, not yet capable of exerting its full power or exhibiting its extreme speed,

it could now be simply stored within his body without any problem,

"Once I find the time, I will refine this treasure further!"

"As long as I refine these ’Thunderbolt Wings’ to Great Success, even if I encounter a Nascent Soul Cultivator in the future, I can escape successfully!"

"Indeed, this time I made the right decision to come here!"

Zhou Xun chuckled lightly, with a thought, the giant pair of wings shrank to a few inches in size, then flew into his body.

After finishing this, Zhou Xun sat cross-legged, took out a Tier Three Middle-Grade Qi Recovery Pill, and swallowed it,

While also operating the Purple Sky True Technique, he began meditating and regulating his breath.

Half a day later, Zhou Xun opened his eyes again, only to see a flash of light in his gaze, looking radiant!

At this time, his Essence, Qi, and Spirit had fully recovered to their peak state.

"Next, it is time to collect my Profound Jade Lotus!"
