Using the Rarity-7 Skill Upgrade Stone on War-King Aura had a simple reason.
Without the stone, the skill was basically capped.
Totem Aura and Ultra Aura shared the same origin—
Their fusion was expected.
But above that?
Bai Chen couldn't imagine any higher-tier aura ability.
And this aura skill, like Nergigante's Strength Incarnation,
was something everyone on the team could learn.
One stone to upgrade a skill that benefited the entire squad—
That alone made it priceless.
Not to mention—
He had discovered a new way to level aura skills:
Defeat Ultra Beasts and absorb their Ultra Aura.
With that, the skill temporarily jumped
from a second-tier ability
to a first-tier one.
Before returning to the Monster Hunter world,
his goal was clear:
Get everyone's aura to Master-level.
Grandmaster?
Not realistic yet.
Bai Chen had already asked Buzzwole.
According to him,
wild Ultra Beasts as strong as he was
were extremely rare.
Buzzwole had defeated countless enemies
to build up his current Ultra Aura.
And he didn't resent Bai Chen absorbing all of it—
After all, Bai Chen beat him fair and square.
Plus—
Buzzwole deeply admired
Bai Chen's perfect muscles.
In the classroom…
Kukui was stunned.
│ "You're saying the bodyguard used a Z-Move himself…
and his partner also used one completely on her own!?"
Kiawe, Mallow, and the others nodded firmly.
There was no mistaking it.
Those were definitely Z-Moves.
Kukui muttered:
│ "Impossible… humans cannot use Z-Moves."
Kiawe asked:
│ "But Professor… could we learn to do that someday?"
Kukui shook his head.
│ "Don't be ridiculous.
A human body can't withstand the energy.
Even Pokémon need trainers to share the burden—
How could we survive it alone?"
│ "Then why can Bai Chen do it?"
│ "…How would I know!?
But one thing's certain—
His physical strength is far beyond normal.
You could try asking Lillie.
He is her family's bodyguard."
Everyone looked at Lillie.
She smiled rigidly
I don't know either.
And if she told them
Bai Chen could also Gigantamax into a 30-meter giant,
What would happen then?
Eventually, she said:
│ "You'll get used to it.
Don't think too hard."
She was already mentally prepared
for Bai Chen to suddenly Mega Evolve someday.
Mallow sighed:
│ "How do you 'get used to' something like this…"
On the field…
Bai Chen had just finished digesting the spoils of battle
When Lusamine walked toward him.
One look at her expression
and he knew exactly what she wanted.
│ "Any progress?"
Lusamine nodded.
│ "Yes.
With Buzzwole helping our research,
and using the wormhole he came through,
We should soon be able to open a stable Ultra Wormhole."
│ "That's good news."
He kept quiet after that.
Lusamine hesitated for two seconds,
then finally asked:
│ "…Could I ask a favor?"
│ "You want me to rescue Faba?"
She nodded.
│ "Even after he hurt Lillie, you still want to save him?"
│ "His crime doesn't warrant death.
I'll punish him justly."
Bai Chen fell silent.
She understood that this was no small request.
They had no idea how dangerous the Ultra World was,
Nor could she guarantee
Their wormhole would stay stable.
If Bai Chen went through and failed to return—
The consequences would be unimaginable.
But realistically,
he was the only candidate.
An outsider who had survived another world.
A world just as dangerous—if not more.
Lusamine said softly:
│ "I understand the difficulty.
I won't force you.
But if you're willing…
I'll offer great compensation."
Bai Chen had already decided to go.
He wanted Ultra Aura
and mountains of skill proficiency.
If he could take a side reward—
even better.
But he kept it clean:
│ "I owe my current strength to your help.
If I refused, I'd feel heartless.
Keep the reward."
He and Lusamine were in a cooperative sweet spot.
Asking for payment now
would only damage trust.
And Lusamine—
with her personality—
would reward him no matter what he said.
Lusamine's eyes lit up.
│ "You're really willing to go!?"
│ "As long as you can stabilize the wormhole,
I don't mind taking a trip."
Lusamine quietly admired him.
│ "Don't worry.
I'll prepare everything thoroughly.
If you were hurt in the Ultra World,
Lillie would never forgive me."
Bai Chen simply smiled.
After school…
Everyone went home.
Buzzwole followed Bai Chen.
Burnet and Wicke had already collected
the research data they needed.
Back home, Indeedee served a large dinner.
Afterward, Bai Chen decided to
Extract the remaining value from Buzzwole—
By having him spar with Nergigante.
On the dueling grounds,
He kept Basarios and Zinogre nearby
in case something went wrong
And no one could restrain Nergigante.
He planned to awaken the forbidden power inside her body.
A month and a half ago,
Lusamine's Bewear hit Nergigante
with a Psychic Headbutt,
triggering that forbidden force by accident.
Now both Buzzwole
and Indeedee
knew moves that could put Nergigante into a state of 100% confusion.
And Bai Chen was far stronger
than he was back then—
He should be able to withstand her chaotic killing intent.
│ "Buzzwole—
Use Lunge Punch on Nergigante."
