To be honest.
Compressing spirit power was truly exhausting.
It not only consumed physical strength, but also mental energy!
As Ye Yu cultivated the Inner Elixir Method and compressed the spirit power within his body, he would be exhausted after barely more than an hour.
He had to rest properly and recover before he could continue.
Fortunately, the enhancement from fusing with the Blue Silver Emperor's Right Leg Bone—
As well as its Second Spirit Skill: Wildfires Cannot Burn It All, Spring Breezes Bring It Back to Life!
Coupled with the four Plant Spirit Beast spirit rings he had absorbed, all of which possessed extremely powerful life force and recovery abilities, they had greatly improved Ye Yu's body's ability to recover.
Therefore, Ye Yu's physical strength recovered very quickly!
As for his mental recovery speed—
When he was not compressing spirit power and was merely cultivating the Inner Elixir Method—
In that Unity of Heaven and Man-like state, his Spiritual Power also recovered quite quickly.
Thus, throughout the night—
Ye Yu would compress his spirit power for a while, then simply meditate and cultivate the Inner Elixir Method before continuing to compress it.
He repeated this cycle over and over!
"A Yu, how is it?"
When the next day arrived—
That morning, seeing Ye Yu finally open his eyes, Dugu Yan's stunningly beautiful face, both glamorous and heroic, immediately filled with anticipation and hope as she asked.
"I'd say I'm halfway there!"
Ye Yu sensed the condition of the spirit power in his body, thought for a moment, and replied.
"The compressed spirit power in my body now takes up about two-thirds of the space it used to occupy in my dantian."
"I feel that, with my current physical constitution, I can continue compressing it."
"I can compress the spirit power in my body to half of what it was before."
"That should roughly be equivalent to around Level 23."
At this point, Ye Yu could not help but sigh.
He wondered how an energy like spirit power could be explained from a scientific perspective.
He had discovered that after compressing his spirit power—
When he cultivated to restore it—
What he restored was spirit power of that compressed quality.
Did spirit power have memory?
Did it remember this state after being compressed?
By now, Heaven Dou Royal Academy was no longer of much use to Ye Yu.
After all—
Ye Yu had initially wanted to enroll in Heaven Dou Royal Academy partly so he could pursue Dugu Yan more conveniently as a fellow student.
The other reason was the valuable books in Heaven Dou Royal Academy's library—
Books related to Spirit Masters and Spirit Beasts.
Especially the books about Plant Spirit Beasts with the Life Attribute, which he needed most.
But because he possessed an eidetic memory—
During his nearly two years at Heaven Dou Royal Academy—
Ye Yu had already read almost all the books in the library that he needed.
So Ye Yu had Dugu Yan ask the academy for another leave of absence, one with no set end date.
He intended to continue compressing his spirit power at the Ice and Fire Yin Yang Well!
And while he was at it, he planned to look over the Thunderclap Body Tempering Technique he had won from Yu Tianheng.
He would study it, learn from it, and practice it for himself.
That would also make it easier for him to create his own lightning body-tempering method in the future!
In the blink of an eye, more than two days passed.
At the Ice and Fire Yin Yang Well—
Ye Yu finally compressed his spirit power to the current limit of his body.
In terms of level—or rather, quantity without considering quality—it had reached the equivalent of Level 23.
Next, he needed to restore his spirit power from Level 23 back to Level 47.
Because his spirit power had been compressed—
When Ye Yu cultivated now—
His spirit power recovered much more slowly than before.
However, in an environment like the Ice and Fire Yin Yang Well, where the spiritual energy of heaven and earth was abundant—
With Blue Silver Emperor A Yin and the vast expanse of newly grown Blue Silver Grass around him serving as a Mimic Training Ground for his martial soul—
When Ye Yu cultivated the Inner Elixir Method—
His spirit power still recovered very quickly.
Under the resonance produced by Ye Yu's Inner Elixir Method, which brought him into Unity of Heaven and Man with the surrounding environment—
Blue Silver Emperor A Yin and the newly grown Blue Silver Grass were also driven along, their cultivation speed greatly increasing!
Especially the Blue Silver Grass.
In the environment of the Ice and Fire Yin Yang Well—
The newly sprouted Blue Silver Grass quickly grew lush and sturdy to a degree that would likely require a year to achieve in the outside world.
After restoring his Level 47 compressed spirit power—
Ye Yu took out the handwritten copy of the Thunderclap Body Tempering Technique from his Jade Dragon Bracelet and began reading it.
It had to be said that, as a self-created soul skill of Douluo Continent—
The cultivation method for the Thunderclap Body Tempering Technique was extremely crude.
Blue Lightning Tyrant Dragon Spirit Masters simply used the Power of Lightning converted from their own spirit power to first stimulate unimportant parts of the body, such as the flesh on the limbs, allowing the body to gradually adapt.
At the same time, they gradually strengthened the Spirit Master's control over the Power of Lightning converted from spirit power.
This allowed the Spirit Master to gain a precise sense and understanding of the intensity of the Power of Lightning converted from spirit power.
Afterward, they could begin using the Power of Lightning to temper their entire bodies.
One crucial point in cultivating the Thunderclap Body Tempering Technique was understanding—
The intensity of the Power of Lightning converted from one's own spirit power.
The Thunderclap Body Tempering Technique described it as Lightning Pressure.
It strictly specified what level of Lightning Pressure should be used to temper the body at the start—
And what level of bodily strength had to be reached before the Lightning Pressure could be increased, among other requirements.
If one rashly used Power of Thunder that was too powerful to temper the body—
The violent Power of Thunder could easily injure the body!
However, Ye Yu felt that he did not need to pay much attention to this.
Because of the Second Spirit Skill of the Blue Silver Emperor's Right Leg Bone, as well as the powerful recovery ability granted to his body by the Life Attribute Plant Spirit Beast spirit rings he had absorbed—
Especially the Lightning Attribute Resistance granted to his body by absorbing the Ten-Thousand-Year Thunderclap Hellvine spirit ring—
He could greatly reduce the damage inflicted by the Power of Lightning while cultivating the Thunderclap Body Tempering Technique.
Moreover, he had the external soul bone, the Thunderclap Netherworld Vine, which could absorb the Power of Lightning.
This meant that the various taboos of cultivating the Thunderclap Body Tempering Technique practically did not exist for him!
A smile appeared on Ye Yu's face.
Afterward, Ye Yu began cultivating the Thunderclap Body Tempering Technique at the Ice and Fire Yin Yang Well.
He first converted spirit power into the Power of Lightning to temper his body.
And aside from converting spirit power into the Power of Lightning—
Ye Yu also had the external soul bone, the Thunderclap Netherworld Spear, which could release the Power of Lightning.
He also had his Third Spirit Skill: Tribulation Ascension, which could directly summon heavenly lightning to temper his body.
In the future, he basically would not need to worry about the intensity of the Power of Lightning being insufficient.
Meanwhile, in Heaven Dou Imperial City—
After Ye Yu completed his transformation—
At Heaven Dou Royal Academy, he had not only displayed overwhelming might by crushing more than a dozen classmates on his own—
He had also effortlessly defeated Yu Tianheng, one of the Blue Lightning Tyrant Dragon Clan's twin stars of the current generation.
This not only shocked Heaven Dou Royal Academy—
Through the word of mouth of the many Heaven Dou Royal Academy students who had witnessed it at the time—
Ye Yu's reputation quickly spread throughout the Spirit Master World of Heaven Dou Imperial City!
Since Ye Yu had enrolled in Heaven Dou Royal Academy through Qian Renxue's recommendation—
To some extent, he could be considered Qian Renxue's man.
After learning of this—
Still in shock, the Heaven Dou Three Committee Members hurriedly reported the news about Ye Yu to Qian Renxue.
They had never imagined—
That Ye Yu, who had enrolled with Innate Level 1 Spirit Power, a Blue Silver Vine martial soul that had only undergone one mutation and evolution, and cultivation at merely Level 10 Soul Warrior—
Would undergo such a complete transformation in just two or three short years.
He had directly become a Soul Elder and overwhelmingly defeated Yu Tianheng, one of the Blue Lightning Tyrant Dragon Clan's twin stars!
His Highness the Crown Prince absolutely could not overlook such a genius!
After absorbing the Thunderclap Hellvine spirit ring, the protagonist's spirit power also gained the Lightning Attribute and could be converted into the Power of Lightning.
