"Congratulations."

Outside the barrier, a rare smile appeared on Lumi's face.

Louis nodded, his expression rather calm.

If he was a sword with a sharp edge in the past, now he had learned to hide that sharpness.

He appeared more harmless now, but in reality, he was even more lethal.

"Is this the power of the Eternal Blade?"

Lumi's gaze shifted to the spiritual body hovering around Louis, and she couldn't help but show an expression of admiration.

A hidden weapon is always more lethal than one that's exposed.

This was the lesson Lumi imparted to Louis through the training.

Louis nodded and said:

"Without Merlin's guidance, it would have been impossible to catch it."

The Kupari Bird is an extremely rare magical creature.

Or rather, it is uncertain if it could even be classified as a magical creature.

After all, it fundamentally lacks magical abilities but possesses supernatural powers.

Dragon's physique + Supersonic flight + Magic power perception.

Even though it has a challenge level of only LV10, its danger and difficulty cannot truly be measured at LV10.

The reason is, the challenge level means "what level of adventurer can challenge it," not representing the ability to capture it.

Additionally, because the Kupari Bird has an extreme aversion to extraordinary energy, this flaw means that if mages are willing to expend magic power, they won't be attacked by it.

It is a magical creature with extremely obvious strengths and weaknesses.

"In the end, it was still a trick."

Louis sighed, "Is this the power of the shepherd tribe's Daya?"

"Had it not been for Master Merlin's help in initiating the [Eternal Training], and the restrictions placed on the Kupari Bird's movement range, along with the allowance to use other extraordinary powers to limit their actions, it would've been impossible to shoot it down."

Hearing Louis's words, Lumi remained silent for a moment.

If it were in a previous life, someone would have told her that Louis was being pretentious.

To have shot down a Kupari Bird in just over ten days was a feat bordering on the godly.

She had never heard of it before.

Even with so many restrictions, the Kupari Bird remained a nearly uncatchable magical creature.

To shoot it down under limited conditions could truly be considered the work of a genius.

Having accomplished in over ten days what ordinary people couldn't achieve in a lifetime, even if His Highness Louis had every favorable factor, was still an exaggeration.

How could His Highness still find fault?

A few hours after the training concluded, while Louis was still recuperating, a little swan rushed to the scene.

Perhaps spurred by Louis's recent strength enhancement, the little swan had genuinely put in a lot of effort these days.

This time, when she came to find him, Louis could clearly sense an extremely active presence of spiritual power within her.

Louis knew this marked an enhancement in the little swan's abilities.

Usually, she controlled her spiritual power well, making it difficult for the ordinary person to sense the volcano-like pressure within her.

But today, it was exposed.

The increase in power had caused her control over her spiritual power to falter.

This situation would only be rectified once she adapted to the expanded power.

"Your Dark Dragon Armament is quite peculiar!"

Seeing Louis in tattered clothes while recuperating, the little swan commented with a strange expression.

Louis furrowed his brows, unsure of what the little swan meant.

The little swan said, "I am almost certain this Dark Dragon Armament is more like a living being without consciousness."

"This thing fits well with your concept of biological weaponry."

"It's more like a bio-enhancement system for function augmentation and modulation."

Louis was taken aback.

This Dark Dragon Armament gave him a sense of déjà vu that grew stronger and stronger.

At first, he thought it was like a buff, directly bestowing him with the power of a dragon.

But after Olivia's research, she stated it wasn't that.

She said it resembled more of a bio-enhancement system for function augmentation and modulation.

He could understand that.

After all, when the Dark Dragon Armament unfolded, the power exhibited did not come out of nowhere. Instead, it resembled a temporary alteration of cellular structure to allow him to express the power characteristics of a dragon.

This couldn't help but remind him of a comic from a previous life—

"Guyver: The Bioboosted Armor"

In the comic, the bioboosted armor was high-tech from a prehistoric civilization.

Though called armor, its essence was a living cell that could grow with its host.

Louis distinctly felt that, in the state of the bioboosted armor, the real change wasn't in his life essence but rather in his cellular transformation.

He couldn't help but recall some information he read in his past life.

In his former life, human cells were categorized as unstable, stable, and permanent cells.

Among them, skeletal muscle cells and cardiac muscle cells are a type of permanent cell.

What we often refer to as muscle fibers is actually skeletal muscle cells.

In daily fitness regimes, some trainers claim that muscle tears and regeneration post high-intensity workouts can enhance muscle cell strength.

People who say this should go back to high school to relearn.

Cells that cannot regenerate do not change after completing cellular differentiation in the womb.

If the cell damage caused during fitness isn't serious, and the muscle membrane remains intact, muscle fibers only partially necrotize. At this point, neutrophils and macrophages will actively clear away the necrotic material, produce muscle plasma, and differentiate into muscle fibers.

In this process, muscle fiber performance can indeed be improved.

However, this has nothing to do with changes in the quantity of muscle cells.

So if the muscle fibers completely break, the muscle fibers during regeneration will cause the ruptured ends to enlarge into bud-like forms to complete self-healing.
