At dawn the next day, as the sky was just getting light, Chu Chengzhou rushed back to Sea God Island.
"Nana, are you ready?"
Casting a glance at Xie Di, the Evil Eye Tyrant Emperor, who stood obediently to the side ready to sacrifice at any time, Chu Chengzhou asked Hu Liena.
Xie Di was a spiritual-type fierce beast, and its race was rather special, a huge eyeball with only tentacles. Under normal circumstances, when it died it would drop only a head spirit bone.
Of course, there was a small chance it would also drop an Evil Eye external spirit bone that likewise enhanced spiritual power.
In that case, there was no need for Hu Liena to refine torso and limb spirit bones and occupy those slots early; he could precisely control Xie Di to drop a head spirit bone.
If, after Xie Di's sacrifice, what dropped was a head spirit bone, then he could remove the sixty-thousand-year Spirit-Condensing Wisdom Skull that Hu Liena already had in her body.
If they got lucky and an external spirit bone dropped, even better.
After all, in the original, Hu Liena had a fox-tail external spirit bone, but perhaps the changes brought by his butterfly effect had been too great, causing Hu Liena to miss that rare external spirit bone; this would make up for it.
"Mm, ready!"
"Come, begin the sacrifice."
At that, Xie Di did not comply as readily as that six-hundred-thousand-plus-year Darkgold Sea Cucumber back then; a violent struggle flashed in its eye.
"Oh? Your will is quite strong?"
Seeing this, Chu Chengzhou raised an eyebrow.
By using the Void Illusion Realm to alter others' consciousness, coupled with his own powerful spiritual force, Chu Chengzhou had never failed in making hundred-thousand-year and above spirit beasts sacrifice. This was the first time he had met one that did not directly cooperate.
It could only be said that Xie Di lived up to being the second-ranked among the Ten Great Fierce Beasts of the later continent, the Evil Eye Tyrant Ruler. Not only was its spiritual power overwhelming, but its will was also extraordinary.
However, the gap in hard strength was not something willpower could bridge; at least Xie Di's will had not reached that level.
At once, azure light flashed over Chu Chengzhou's body, and the Nine Heavens Chaos Armor manifested.
At the same time, the True Spirit Banner martial soul appeared in his hand, his ninth spirit ring shone, and Xiao Guang, the Dragon of Time, condensed beside him, then turned into a platinum stream of light and merged into his body.
With the battle armor manifested and entering spirit-form, Chu Chengzhou's spiritual power surged, and he once again activated the Void Illusion Realm.
Immediately, the struggle in Xie Di's eye faded. Black-violet light flashed over its body, its form shifted, revealing the Evil Eye Tyrant Emperor's true body, and it began the sacrifice.
Before long, the sacrificial rite reached its final stage.
The gold-patterned bloodflame ring pulsing around Hu Liena suddenly contracted. In an instant, the Star-Moon Nine-Tailed Fox martial soul surfaced and possessed her. The seven spirit rings she already had (yellow, yellow, purple, purple, black, black, red) appeared one by one. Then the contracting gold-patterned bloodflame ring transformed into a blood-red eighth spirit ring marked with seven golden streaks.
At the same time, a beam of blood light shone upon Hu Liena's forehead. The black-violet shadow of a single eye flashed and vanished. On the massive corpse left after Xie Di's sacrifice, a head spirit bone of the same black-violet hue appeared.
"Two spirit bones?"
Chu Chengzhou's eyes widened in disbelief.
A spirit beast of a hundred thousand years and above would always drop a spirit bone upon death, but in general only a single hundred-thousand-year bone.
Since there was a general case, there were exceptions.
For example, Bibi Dong. When she hunted the hundred-thousand-year Death Spider Emperor in the past, she hit the jackpot and two hundred-thousand-year spirit bones dropped at once.
Although the slots were not the relatively more precious head and torso, a pair of left-right arm bones was still very good.
Either way, two different hundred-thousand-year arm bones were still worth more than a single hundred-thousand-year head or torso bone.
Who would have thought Hu Liena's luck would be even more heaven-defying: not only a head spirit bone, but even an external spirit bone.
While Chu Chengzhou was still dazed, Hu Liena's eighth spirit ring settled. Her spirit power broke through the level 80 bottleneck and instantly surged to level 87 Spirit Douluo.
Now formally an eight-ring Spirit Douluo, feeling the surging spirit power within her, she lowered her head to look at the eighth spirit ring blooming on her body with seven golden patterns, and could not help grinning foolishly.
"Stop grinning. There's another spirit bone here."
Seeing her like that, Chu Chengzhou spoke.
At his words, Hu Liena raised her head to see Chu Chengzhou handing over a black-violet head spirit bone as deep as a dark abyss.
"This is..."
Looking at the head spirit bone he handed her, Hu Liena was puzzled.
"What else could it be? You got dumb luck."
"You're the one with dumb luck!"
Hu Liena shot Chu Chengzhou a glare, then happily took the head spirit bone and examined it with satisfaction.
This was a head spirit bone of over seven hundred thousand years. There was probably only this one on the entire continent.
"All right, enough preening. I'll remove your Spirit-Condensing Wisdom Skull first."
Chu Chengzhou said with a smile.
"Mm, hurry up!"
In less than a quarter of an hour, Chu Chengzhou had removed the Spirit-Condensing Wisdom Skull from Hu Liena.
But refining the Evil Eye Tyrant head spirit bone would take far longer. The vast spiritual power within it was not something Hu Liena could completely refine in a short time.
Time passed. The sun and moon turned. In the blink of an eye it was the morning of the third day.
After two days and two nights, the refinement of the Evil Eye Tyrant head spirit bone was nearing its end.
Suddenly, the fluctuations of spiritual power around Hu Liena gradually subsided, stabilizing near the Limit Douluo level. Then she opened her eyes.
"How do you feel?"
Seeing her wake, Chu Chengzhou stepped forward and asked.
"Your aunt is invincible now!"
After carefully sensing herself, Hu Liena raised her chin and spoke with full confidence.
"Give it a rest. You're still far from invincible."
Chu Chengzhou said, not amused.
Although, thanks to the Evil Eye Tyrant head spirit bone and the Evil Eye external spirit bone, Hu Liena's spiritual power had risen to the brink of the Limit realm, calling it invincible was still a stretch.
Still, even if not unmatched under heaven, Hu Liena at this moment was enough to rank among the continent's top experts.
With spiritual power near Limit Douluo level, and an eighth spirit skill and bone skill of over seven hundred thousand years, even the level 98 Golden Crocodile Douluo would have to kneel.
It was not that the Golden Crocodile's strength was lacking, but in this era most Spirit Masters did not emphasize training spiritual power, or rather had no effective method to cultivate it. Compared to their spirit power, spiritual power was generally the weak link.
