According to the God and Devil Tyrant Body Art, these interwoven black-and-white god and devil patterns were Innate God and Devil Qi.
They were also the key to mastering the God and Devil Tyrant Body Art.
The moment Innate God and Devil Qi spread through every piece of flesh, every bone, and every inch of skin, he would have completed the first level of the God and Devil Tyrant Body.
Qin Wuyou had finally found his way in.
His divine sense focused entirely on studying the Primordial God and Devil Visualization Diagram, while his body absorbed the power of heaven and earth, automatically condensing it into Innate God and Devil Qi.
Roughly every minute, another strand of Innate God and Devil Qi formed within his body.
This speed was already astonishing.
Yet to Qin Wuyou, it still felt too slow.
According to the God and Devil Tyrant Body Art, even the first level of the God and Devil Tyrant Body required him to condense 108,000 strands of Innate God and Devil Qi within his body before it could truly permeate all his flesh and bones.
At his current speed, it would take several months to complete the first turn of the God and Devil Tyrant Body.
And that was assuming he went without sleep or rest the entire time.
If he factored in time to rest, it would take more than twice as long.
In other words, under normal circumstances, he would need at least a year to have any hope of completing the first turn of the God and Devil Tyrant Body.
Qin Wuyou could not wait that long.
He wished he could master the God and Devil Tyrant Body right now.
Now, the black Demon Blood Essence he had collected from the demons he had slain earlier came in handy.
With a turn of his palm, countless sealed portions of black Demon Blood Essence appeared before him.
Over the past few days, he had accumulated enough Demon Blood Essence to form a small mountain if he took it all out.
What lay before him was only one percent of it.
He had gathered this Demon Blood Essence to cultivate the God and Devil Tyrant Body Art in the first place!
Now was the time to put it to use.
As he absorbed the portions of Demon Blood Essence one after another, his body rapidly grew stronger.
At the same time, the rate at which Innate God and Devil Qi formed within him abruptly increased.
By the time he had absorbed all the demon blood essence before him, two hours had passed.
In those mere two hours, the Innate God and Devil Qi within his body had increased by a full 360 strands!
His speed of condensing Innate God and Devil Qi had increased more than threefold!
At this rate, if he went without sleep or rest, he could complete the first turn of the God and Devil Tyrant Body in just over ten days!
Yet Qin Wuyou was still far from satisfied with this speed.
"Demon Blood Essence from demons in the Essence Condensation Realm is still a little too weak."
"If I can collect large quantities of Demon Blood Essence from demons in the Foundation Establishment Realm, I'll definitely master the God and Devil Tyrant Body faster!"
Demons in the Foundation Establishment Realm had undergone another round of bodily tempering, and the quality of their blood essence was more than ten times that of those in the Essence Condensation Realm.
Its effects would also be far better than those of Demon Blood Essence from the Essence Condensation Realm!
Yet now was not the best time to go out and slay demons in the Foundation Establishment Realm.
He was no fool.
When he had traveled through the Underground Cavern World in his Kunpeng avatar earlier, he had already noticed cultivators in the Underground Cavern searching for him like madmen, carrying portraits of his transformed appearance.
After some thought, Qin Wuyou quickly realized that he must have drawn the attention of someone with an agenda by killing too many demons in the Essence Condensation Realm on the third level of the Underground Cavern.
So if Qin Wuyou made another move, he would have to be even more cautious.
After all, his cultivation was only at the Foundation Establishment Realm. If he really encountered the Seven Kills Hall's Primordial Spirit Realm Deputy Hall Master, he might not be able to defeat him.
Until he was absolutely certain, Qin Wuyou had no intention of meeting his opponent head-on.
"Cultivate! Once I master the God and Devil Tyrant Body, my flesh will be able to withstand attacks from Spirit Artifacts!"
Divine light flickered in Qin Wuyou's eyes.
The body was the very foundation of cultivation.
Only an imperishable body could endure through the ages.
That was why he placed such importance on cultivating his body.
As he devoured and absorbed portion after portion of demon blood essence, earth-shaking changes took place within his body.
Countless strands of Innate God and Devil Qi filled every part of his body, transforming his flesh, bones, and skin.
His flesh became radiant and crystalline, his bones turned translucent like glazed glass, and even his internal organs became more extraordinary under the tempering of Innate God and Devil Qi.
But what truly delighted Qin Wuyou was the Supreme Bone within him!
His Supreme Bone lay along his spine and was only as long as his thumb. Ever since his birth, it had remained unawakened.
Originally, this Supreme Bone had shone a brilliant gold, as though cast from pure gold.
Now, however, a layer of sealing power left by his Lineage's Emperor-to-be ancestor covered it.
This seal did not suppress his Supreme Bone. Instead, it concealed the Supreme Bone's aura and radiance.
Unless someone's strength surpassed that of the Qin Family's Emperor-to-be ancestor, no one could discover the Supreme Bone within him.
Simply put, it was a form of protection.
After all, a gift like the Supreme Bone was far too shocking.
If anyone learned that he possessed a Supreme Bone, it would stir up towering waves.
Even those undying old monsters in the Upper Realm would likely be tempted, and might even move to seize his Supreme Bone.
Though he possessed a Supreme Bone, he lacked the strength to protect it.
He clearly remembered the lesson that Emperor-to-be ancestor had taught him back then.
"Boy, tell me. What do you think is the greatest thing in this world?"
"The sky."
Qin Wuyou, only three years old at the time, had answered in his childish little voice.
"Wrong."
The Emperor-to-be ancestor had narrowed his eyes and smiled.
"Then it's the earth."
"Wrong again."
"The starry sky."
"Still wrong."
"The sun? The moon? The sea?"
That day, Qin Wuyou had offered countless answers, but his ancestor had rejected them all.
"Ancestor, are you tricking me?"
Three-year-old Qin Wuyou had tilted his head, growing a little angry.
"Boy, listen carefully."
"You are the greatest!"
The moment he saw the Emperor-to-be ancestor's fingertip touch his little nose, Qin Wuyou had frozen in bewilderment.
"Me?"
Qin Wuyou had looked down at his little arms and legs and said in disbelief,
"You're lying, Ancestor! I'm only this big. I'm not even as big as you, so how could I be the greatest? You're tricking me!"
"Am I?"
The Emperor-to-be ancestor had chuckled, gently rubbed Qin Wuyou's little head, and said kindly, "Boy, remember what I told you today. You'll understand in the future."
Back then, Qin Wuyou had been unable to grasp his ancestor's words.
But now, he understood.
The greatest thing in this world truly was himself!
Of course, that was only from his own perspective!
So that day, his ancestor had placed a seal on his Supreme Bone and told him not to remove it until he possessed the strength of a Saint King.
Qin Wuyou still remembered tilting his head and asking with an innocent expression,
"Why?"
His ancestor had remained as kindly as ever, chuckling as he said, "Once you reach the Saint King Realm, you'll understand."
