The B-grade dark energy spirit crystal that Mo Yu spat out was obtained by Wang Sen after killing a B-grade early stage demonic tiger not long ago. It contained nearly 10,000 spirit energy, which not only fully replenished his spirit energy but also refilled the depleted spirit energy within his Pure Land space, with some left over.
Unlike the goose egg size of C-grade dark energy spirit crystals, B-grade ones were condensed to the size of a pigeon egg, covered with naturally formed intricate patterns. These patterns represented the circulation routes of dark spiritual energy within the bodies of secret realm demonic beasts when they used various skills.
At this moment, only a small half of the demonic crystal remained in Yu Zhibo's hand, and because the spirit energy concentration within his Pure Land space had reached saturation, it stopped volatilizing.
This made Yu Zhibo somewhat delighted.
It meant that as long as he placed more purified dark energy spirit crystals in the space, he could rely on their volatilization characteristic to continuously replenish the spirit energy within the space, and it would never be wasted.
Although it wouldn't be inexhaustible spirit energy, his recovery speed would greatly increase. Yu Zhibo's expression was excited. He then had Mo Yu spit out another 10 dark energy spirit crystals and began purifying them with lightning techniques.
An hour later, ten B-grade light energy spirit crystals of varying sizes were placed in a corner of the Pure Land's center, resembling a small pile of gems.
Yu Zhibo split off a clone and allocated 2,000 points of spirit energy to it, instantly emptying his own spirit energy.
Because he was currently inside the space, rather than the space being inside him, the sequence core could not directly access the spirit energy within the space at will.
Therefore, he began to circulate the sequence core to plunder the rich spirit energy within the space to replenish himself.
Soon, the saturated spirit energy concentration within the space began to decrease, and then it was rapidly replenished by the spirit energy volatilizing from the pile of light energy spirit crystals in the corner.
"Haha!" Yu Zhibo's eyes lit up. From now on, insufficient spirit energy would no longer be his weakness.
"It's been two hours. I wonder how things are outside," Yu Zhibo murmured, then looked at his clone, "You go out and take a look."
With a thought, he sent the clone out of the space.
As a result, less than a second later, he began to grimace and convulse all over, because after the clone appeared in the outside world, it was instantly obliterated by the Chaotic Demon Bat that was lying in wait outside.
And as the clone was destroyed, he felt the bottleneck that had troubled him for a long time (days) loosen slightly.
This made Yu Zhibo happy, but he quickly felt it was only natural.
After all, after he separated from the team, he used the abilities of his Sharingan, combined with the Body Flicker Technique, to dodge the Demon Bat's attacks. Almost every movement was like dancing on the tip of a knife, equivalent to experiencing dozens of near-death crises.
Coupled with the death of the clone, it was equivalent to dying once more. Therefore, the loosening of the bottleneck seemed only natural.
"Since I can't go out now, I'll just cultivate."
Murmuring, Yu Zhibo sank his consciousness into the sequence core, controlling the Mangekyo-shaped sequence core like a millstone, grinding and absorbing the rich spirit energy within the space to increase the density and capacity of his spirit energy.
Soon, his spirit energy broke through the 2,600-point mark and began to rise.
Two hours later.
Yu Zhibo slowly opened his eyes. At this moment, the spirit energy capacity of his sequence core had reached 3,600 points, leaving him 1,400 points short of the D-grade benchmark of 5,000 points.
Then, the sequence core within his body began to rotate automatically, forming a small vortex at his Dantian outside his body. Instantly, the spirit energy in the space surged backward and poured into his body like a torrent. It was then transported by the sequence core to all parts of his body, beginning to transform his physique.
Another hour later, when Yu Zhibo opened his eyes again, his body had significantly strengthened. His Physique, Strength, Agility, and Constitution had all improved to varying degrees. Moreover, his mental power, which had been depleted due to the clone's death not long ago, had been fully restored.
Looking at his status panel, this promotion had directly increased his mental power to 2,900 Hertz, surpassing the mid-stage C-grade level. His Strength, Agility, and Constitution attributes had all exceeded 90 points, bringing him exceptionally close to the C-grade benchmark of 100 points.
"Since experiencing life and death can loosen my bottleneck, then I can only inconvenience you all."
A determined look appeared on Yu Zhibo's face. He then split off eight more clones, instantly filling the entire space, even stepping on Mo Yu, who was lying on the ground eating dried fish.
Yu Zhibo allocated 400 points of spirit energy to each clone and instructed them to immediately use the Body Flicker Technique upon exiting, escaping in eight different directions. After escaping, they were to find Ling Xiaotian and the others.
Then, with a thought, he sent all the clones out simultaneously, his face filled with anticipation, clearly placing great hope on his clones.
Then he clutched his head and began to scream and writhe on the ground.
There was no luck. With the peak B-grade Chaotic Demon Bat lying in wait, the moment the eight clones appeared, before they could even use the Body Flicker Technique, they were killed by the pre-prepared sonic attack from the Demon Bat.
With the simultaneous death of the eight clones, Yu Zhibo's brain felt a tearing pain. His mental power plummeted from 2,900 Hertz to a mere 100 Hertz, followed by superimposed physical pain, which almost made him faint.
His eyes were bloodshot, veins bulging on his forehead. He rolled around on the ground, frantically pounding the earth with his hands.
Mo Yu was terrified. It pushed the dried fish in front of it aside with a paw and meowed anxiously around Yu Zhibo, pacing back and forth in distress.
After a long while, Yu Zhibo's writhing body began to calm down slowly. He raised his head, his eyes bloodshot, his face covered in tears and snot, looking utterly pathetic.
Han Chen and Zhao Tianru were recovering by sitting cross-legged after taking medicine. Ye Ling, however, sat in the corner hugging her knees, her eyes red, her mind replaying the scene of Yu Zhibo luring away the Chaotic Demon Bat.
"Don't be sad. Little Yu might not be dead yet! I personally saw him retreat into his own space. This time, he should be able to overcome the crisis in the same way."
Hearing this, Ye Ling suddenly looked up, her face filled with hope as she looked at the speaker. "Really?"
The speaker was Wang Sen. He leaned against the wall with his eyes closed and said faintly, "Don't worry. Abandoning our comrades has never been the style of our Shenhua Bureau. Not to mention the large amount of supplies he carries, just the fact that he sacrificed himself to lure the Demon Bat away for you is enough reason for us to rescue him."
"Mhm!" Ye Ling nodded heavily, finally feeling a little better.
Wang Sen glanced at her, shook his head with a smile, and closed his eyes again.
