The training room dedicated to the Chairman was much more spacious than Yuu had imagined.
It had wooden floors, walls covered in thick, reinforced shock-absorbing tiles, and the lighting was brighter than in ordinary rooms.
After bidding farewell to Beans.
Yuu stood alone in the training room, recalling Netero's questions from earlier, speculating:
"The final exam usually tests the candidates' actual combat abilities."
"Either fighting the examiners, dueling that guy Hisoka, or possibly even Netero himself acting as the examiner."
"Facing average examiners is one thing, but if I'm up against a powerhouse like Hisoka or Netero, trying to beat them without using 'Blue', my only trump card, would be a pipe dream..."
Currently, Yuu's most lethal move was the maximum output "Blue," which could easily destroy buildings and land within a twenty-meter radius of the singularity.
The downside was that it took longer to charge than a standard "Blue."
Also, its movement speed was extremely slow. Unless he caught them off guard, it would be difficult to hit Nen masters with keen senses.
Aside from that, Yuu's only other viable move was "Cursed Ren," a derivative combining "Ren" and "Cursed Energy."
In this state, his speed, strength, and explosive power would be more than ten times his normal state, but the stamina consumption was also multiplied.
Also affected by the duration of "Ren," the maximum duration was currently only about 15 minutes. The downside was that it temporarily could not be activated simultaneously with the "Limitless Technique."
"Going down the list... it's really just hand-to-hand combat skills."
Thinking of this, Yuu couldn't help but sigh...
Before mastering the "Reverse Cursed Technique," the attack methods of the "Limitless Technique" were simply too limited.
Considering these factors, he decided to cram at the last minute and try to develop some offensive means for his Nen ability.
"Two days is really a bit short... obviously not enough to develop new moves, at most I can only try to verify various previous conjectures."
Yuu had many inspirations in his mind, but he hadn't had the time to verify them before.
"Kuro, time to work."
Yuu summoned his gluttonous and sleepy black cat Nen beast after a long time and said to it.
Hearing this, Kuro meowed reluctantly a few times, looking particularly lazy.
[The Greedy Metamorphic Demon Cat]
Conjures a two-tailed black cat capable of swallowing 'Nen' and most 'physically existing' things.
This was Yuu's Nen ability.
"Kuro can swallow and digest 'Nen', but can also choose not to digest it, converting the swallowed 'Nen' into 'Nen pills' that can be used to replenish Nen."
This was a phenomenon Yuu discovered when Kuro was still a worm.
Regarding this function, the simplest usage was to feed Kuro the surplus 'Nen' daily to make replenishable 'Nen pills'.
Like mana potions in a game, they could effectively alleviate the problem of insufficient 'aura' during combat.
"However, 'Nen pills' will only not dissipate over time when stored in Kuro's stomach, and 'Nen pills' occupy part of Kuro's 'appetite'.
"This means that when storing a large number of 'Nen pills', the amount Kuro can swallow will be greatly discounted."
An hour later.
Yuu mentally commanded Kuro to continuously swallow the Nen around him, creating more than 10 Nen pills.
The amount of Nen contained within them was basically equal to the amount of Nen swallowed. And unlike the one accidentally produced at the very beginning...
These Nen pills were marked with the character "100" on the surface, obviously indicating that the absolute value of Nen contained within was one hundred points.
And the total of over a thousand points from these dozen pills... was Yuu's current total amount of 'Nen'.
"Although my absolute Nen volume is less than Hisoka's, if I include these 'Nen pills', even a beginner like me can utilize a considerable amount of 'Nen volume' in battle."
Thinking of this, Yuu suddenly realized...
His Nen ability seemed more useful than he thought.
Unfortunately, the amount of Nen contained in the 'Nen pills' stored by the Nen beast could not exceed twice Yuu's own capacity. In other words, the Demon Cat's stomach could currently only hold a little over twenty pills.
Once exceeded, all the Nen pills would slowly dissipate just like in the outside world.
This could be considered a restriction existing within the Nen ability itself, just like the many restrictions existing when Chrollo's [Skill Hunter] steals others' Nen abilities. It wasn't something the Nen user could change at will.
An hour later.
Through testing during this period.
Yuu also discovered two ways to use these Nen pills.
One was to crush them directly. The 'Nen' contained within would automatically attach to the external Nen... that is, the 'Manifested Aura Volume', slightly increasing defensive power.
The other was by swallowing, increasing the 'Potential Aura Volume' within the body, which could improve physical functions to a certain extent, increase self-recovery ability, and alleviate pain.
"However, although swallowing 'Nen pills' can alleviate injuries, given the characteristics of these 'Nen pills', they could most likely also be used to help ordinary people sense 'Nen' without any harm."
"If given freely to ordinary people, it might create a terrifying Nen user overnight. Must be used properly."
Yuu understood this and continued to seize the time to study his own abilities.
Time ticked by.
Soon, only a few hours remained until the official start of the exam.
And Yuu became increasingly obsessed with verifying his previous conjectures, indulging in the journey of exploring Nen abilities... almost forgetting the time.
Besides 'the usage of Nen pills'.
Yuu discovered two more noteworthy points.
The first was that Kuro... the Nen beast itself could also choose to digest the 'Nen pills' in its body, thereby briefly enhancing its physical functions, including 'digestive ability'.
This function could help it accelerate the digestion of 'Nen' in its stomach.
And the second concerned the type of 'Nen pills'.
When Yuu tried to use the technique of 'Hatsu' to mix the malice in his heart into the surrounding 'Nen' for Kuro to swallow...
The 'Nen pills' produced in this situation no longer appeared turbid white like pearls as before, but had an unidentified black mist swirling within them.
And these black-tinged 'Nen pills', after Yuu's cautious testing...
The moment they were crushed... the black Nen pills would instantly unleash the offensive 'Nen' within them into the immediate vicinity.
Like a small bomb.
The power was slightly greater than attacking with 'Nen' normally.
Before the test, Yuu keenly sensed the dangerous aura emanating from it and kept the "Limitless Technique" active the whole time, so he wasn't harmed during the testing process.
"I just don't know if I can swallow the enemy's 'Nen' and turn it into offensive black Nen pills as well."
With this conjecture in mind, the mentally exhausted Yuu yawned, lay down, and fell into a deep sleep.
Until the airship arrived at the destination and Beans' voice spread to every corner again...
Yuu woke up again.
"The airship has arrived at the destination. Candidates, please follow the guide at the exit to the final stop of this assessment after hearing the broadcast."
"The final assessment will officially begin within an hour. Candidates, please arrange your time reasonably."
"That is all."
