Speechless.
Yuzhou was completely speechless.
At this point, it was obvious why the Science and Technology Bureau of the Land of Light was constantly getting robbed.
Security issues aside—
that safe alone was doing half the work.
"Tiga, this is for you—basic scientific research knowledge."
As he spoke, Hikari produced a data chip and handed it to Yuzhou.
"Huh? This thing…"
Yuzhou stared at the chip in confusion, having absolutely no idea how he was supposed to use it.
"This chip contains foundational scientific knowledge," Hikari explained.
"The volume of information is massive. If you tried to memorize it normally, it would take an extremely long time."
"Instead, it uses Light Memory Transfer, allowing you to absorb the knowledge rapidly."
"Then wouldn't higher-level knowledge work the same way?"
Yuzhou's eyes lit up with pleasant surprise.
"No."
Hikari shook his head.
"In science, there is only basic and non-basic knowledge."
"Advanced science must be obtained through experimentation, step by step—not through direct knowledge transfer."
"Every experiment contains countless possible outcomes."
"I see."
Yuzhou nodded, finally understanding Hikari's point.
In short—
practice is the sole criterion for testing truth.
"Knowledge gained from books always feels shallow. True understanding comes only through action."
Yuzhou converted the chip into light and absorbed it into his body.
Instantly, a vast amount of scientific knowledge surfaced in his mind.
It didn't feel forcibly implanted—
rather, as if these memories had always belonged to him, merely lying dormant until now.
"By the way," Yuzhou asked suddenly, "can I use this Sublimator too?"
He felt an urge to try Sublimation himself.
"Of course."
Hikari nodded readily and handed the Sublimator to Yuzhou.
He also produced three Ultra Medals and passed them over.
"Cosmos, Agul… and your medal too, Hikari."
Looking at the medals in his hand, Yuzhou glanced at Hikari with confusion.
"Just try it," Hikari said, offering no further explanation.
"Alright."
Yuzhou pressed the activation button.
A dimensional light gate opened before him.
He understood immediately—this was the Sublimation Space, where time flowed differently.
One minute inside equalled one second outside.
Without hesitation, Yuzhou stepped in.
"Yuzhou—access granted!"
An identity card formed in his hand and was inserted into the Sublimator.
The Sublimation Space responded with authorization.
"Ultraman Cosmos!"
"Ultraman Agul!"
"Ultraman Hikari!"
Yuzhou inserted the three medals and pulled the activation lever three times in succession.
Energy surged forth.
"Ultraman Tiga!"
Three streams of blue energy fused into Yuzhou's body.
Within the intersecting light, his appearance underwent a dramatic transformation.
His entire body turned silver-blue.
Multiple medals appeared embedded across his chest.
At the same time, two bracelets materialized on his wrists.
With a thought, both bracelets released blades of light.
One carried Hikari's sharp, technological aura.
The other radiated Agul's deep, oceanic power.
Next, Yuzhou felt light as air—so weightless that he almost felt like performing a round of Tai Chi.
A gentle wave of light flowed from his hands, passing through Hikari's body.
Seeing the look of clear enjoyment on Hikari's face, Yuzhou immediately understood.
Cosmos' Full Moon Light Wave.
A purification ability used on monsters.
"Sublimation successful," Hikari said, shaking off the lingering comfort.
"How does it feel?"
"Pretty good," Yuzhou replied honestly.
He couldn't think of a better description.
"Besides these abilities," Hikari said, examining Yuzhou's silver-blue form, "you should possess additional powers."
"For example, when fighting in the ocean, your energy will continuously regenerate. That's Agul's power."
"A passive ability like that?"
Yuzhou nodded appreciatively.
"Very nice."
"If you like it," Hikari said casually, "then consider it a gift."
He handed the Sublimator to Yuzhou outright and, in addition to the three medals, gave him a large stack of blank medals.
Yuzhou could collect Ultra powers himself.
"There's such a good deal?!"
More than receiving the Sublimator, what truly thrilled Yuzhou were the blank medals.
If he ever needed the power of some absurdly strong Ultraman—
Thick skin or not, asking for energy was totally an option.
Saga.
Noa.
Ultraman King.
Legend.
If he gathered medals like those and performed a fusion sublimation—
Wouldn't that be outright invincible?
"Well then, Hikari—I've got things to do, so I'll be heading out."
Yuzhou deactivated the Sublimation, left the Science Bureau, and flew toward the Space Garrison Headquarters.
Unfortunately, Ultraman King was off wandering who-knew-where again. Otherwise, Yuzhou would absolutely have gone to borrow some power.
"Captain Zoffy!"
The moment Yuzhou entered the Garrison, he spotted Zoffy.
Approaching quickly, he took out a blank medal.
"Captain Zoffy, in preparation for our battle against Tartarus—
may I borrow some of your power?"
Yuzhou spoke with utmost seriousness.
This man's strength was something even Belial struggled to suppress.
If it could be borrowed, then it absolutely should be.
"Of course!"
Zoffy agreed immediately upon hearing Tartarus' name.
A stream of light flowed from Zoffy into the blank medal.
With a flash, Zoffy's emblem appeared.
"Thank you, Lord Zoffy!"
Yuzhou said excitedly, bowing his head.
"…Lord?"
Zoffy blinked in confusion.
But Yuzhou had already moved on, approaching the other Ultra Brothers one by one, collecting their medals in turn.
Hikari had given him so many blank medals it was practically ridiculous.
Not using them would be a waste.
After collecting all the Ultra Brothers' medals, Yuzhou turned his gaze toward Father of Ultra.
Truth be told, talking to the elders of the Land of Light was never easy.
In another timeline, Yuzhou was quite close with Ken—
But here, things were different.
"Come," Father of Ultra said first, raising a hand.
"For the sake of universal peace, I too will contribute my strength."
Yuzhou was overjoyed and quickly offered a blank medal.
Moments later, amid flashing light, Father of Ultra's medal was completed.
"I'll contribute as well."
To Yuzhou's surprise, Mother of Ultra stepped forward.
Though slightly embarrassed, Yuzhou still handed her a medal.
With a soft flash—
Mother of Ultra's image appeared upon it.
