"With sufficient energy, half a day is sufficient."

In this desolate world, Death Energy and Dark Energy are extremely abundant.

Unfortunately, these energies have been eroded by the Abyss, tainted with Abyssal Aura. If absorbed directly without refining, one would be contaminated by the Abyss and become an Abyssal creature.

Kasi is strong, yet he doesn't dare to absorb these energies directly, needing to refine them bit by bit before absorption.

Therefore, the speed of restoring strength is severely slowed down.

"Can other energies be absorbed?"

Specialized Dark Energy or Death Energy, absorbing Dark Crystals and Death Crystals works best.

But this world is entirely contaminated by the Abyss, and these resources no longer exist.

However, Mo Qingchen and the others come from the outside world, and the things they carry have not been polluted by the Abyss.

The Female Demon Beast has quite a few Dark Crystals on her, and the lowest is of Tier Six quality.

However, she doesn't plan to take them out directly but instead asks if other energies can be used as a substitute.

"As long as it's not energy polluted by the Abyss, it can be absorbed. However, it needs to be converted first, which will delay some time. But as long as there's enough energy, I am confident of restoring to peak condition within a day."

Kasi nodded, but his eyes were drawn to the transparent dome that had covered him earlier.

He remembered it vividly.

The terrifying electric arc and thunder were actually a type of energy that, with a little processing, could also be absorbed.

The war machine they are in must harbor immense energy in its Energy Core; otherwise, it couldn't have unleashed such formidable thunder to inflict fatal harm on him.

"Grey Wolf, put him back in and inject reactor energy to see if it can be absorbed."

The Female Demon Beast's eyes glanced over, and Mo Qingchen naturally understood her thoughts, directly instructing Grey Wolf beside him.

"The nature of energy conversion is a research-worthy topic."

Grey Wolf nodded, pushing Kasi lightly back into the pale blue dome.

Then he opened the control panel, his claws becoming a blur of afterimages. With a series of operations, the dome that had just been releasing arcs and gathering thunder was now directly filled with immense energy.

The nuclear energy generated by the reactor was converted through the Wolf King's transformation into a pure pale blue energy.

In almost a minute, this pure energy filled the entire dome.

"What a special and pure energy. With enough of it, not only can I restore to my peak condition, but I could even return to the Tier Nine Peak from my past life."

Kasi felt the surrounding energy in ecstasy, expressing his admiration.

The next moment, a black hole appeared on his body surface, and the abundant pure energy, as if finding an outlet, surged into the black hole.

Immense energy was gradually converted into Dark Energy within the black hole, then integrated into Kasi's body.

His strength kept increasing at this moment.

The Level was continuously rising.

The Tier was easily breached.

Yet the external energy wasn't fully absorbed by him; instead, under Grey Wolf's control, it was continuously injected into the dome.

Numerous energies being infused, Kasi's power soared, breezing through each realm effortlessly.

The Tier Eight LV89 Level was reached in just a short half day.

But he didn't stop, absorbing even faster, as if fearing Grey Wolf would cut off the energy.

Grey Wolf, undisturbed by this guy's little schemes, continued to infuse energy while checking the constantly changing parameters on the screen.

These parameters were extremely detailed, and naturally, the data source was Kasi himself.

It could be said that ever since this guy entered, the Wolf King's detectors and radar have not paused for even a split second.

The entire process was recorded, and after parameter comparison, it was clear that Kasi's strength had now returned to the Tier Eight peak level.

And at this moment, without halting the energy infusion, it was very clear he had some plans, possibly intending to take advantage of the immense energy to break through the current bottleneck and step into Tier Nine.

In fact, as they expected, after another half day's persistence, an immensely powerful spirit wave erupted from Kasi's body.

The next moment, the black hole formed on his body surface abruptly expanded.

The energy within the dome surged into the black hole like a flood.

Almost instantaneously, the energy that filled the dome visibly disappeared.

"Is this about to break through? The ability isn't enough, so let's keep infusing! Wolf King, activate the overload mode for energy infusion!"

With a simple operation, the entire Wolf King vehicle lightly shook.

Then, energy almost turned tangible and began filling the dome.

Under 200% energy overload, the energy that had just visibly disappeared slowly became abundant again.

And this increase in energy made Kasi relax his previously tense heart.

He initially thought that the energy would run out while trying to break through, leading to being stuck and failing to break through successfully.

Unexpectedly, this little werewolf had a backup, so he had nothing to worry about now.

In such an abundant energy environment, and with such pure energy, it only needed a little circulation to be directly absorbed.

Such a good environment, what better time to break through the realm?

Having made up his mind, Kasi no longer paid attention to the outside of the dome, but instead focused on breaking through.

Countless energies, under the constraints of the half-ghost, half-witch demon form, were subdued one by one from a chaotic state, and then began circulating throughout his body according to a specific route.

His body opened all apertures, and his meridians flowed smoothly. Finally, under the wash of immense energy, they gathered in his mind.

As countless energies surged, his entire mind was as if a door had been pushed open, bursting wide.

The next moment, Kasi's momentum surged rapidly, and simultaneously his Tier advanced from Tier Eight to Tier Nine, the Level leaping from LV89 to become LV90!

Successful tier breakthrough, realm advancement, level leap...

Tier Nine Witch Demon Cassie felt the immense energy within and couldn't help but curl his lips into a smile, looking exceptionally chilling and cold.

Meanwhile, the black hole on his body surface expanded once more, directly covering the interior of the dome.

The energy infused into the dome was almost instantly exhausted, all absorbed by him.

Furthermore, due to the strong absorption force of the black hole, even the channel for injecting energy was forcibly absorbed.

At this moment, Kasi's Level, which was just Tier Nine LV90, climbed steadily until it reached LV92 before finally stopping.
