Taking on a personal disciple could be considered either necessary or unnecessary, it all depended on one's own choice.
Yi Tianyun currently possessed countless treasures, yet had no one suitable to pass them on to. Even Yi Sixue and Shi Xueyun weren't fully compatible with his inheritance, so he couldn't teach them everything he knew.
What he needed was a disciple compatible with the martial arts he cultivated, only then could he properly pass on his legacy. The benefit of this was clear, not only gaining a loyal disciple, but potentially nurturing a future powerhouse!
If there was one thing he had in abundance, it was resources. Training a disciple would be incredibly fast, just pour resources into them relentlessly. Top-tier Heavenly Dao martial arts? Not even an issue.
However, he had yet to find someone who met his requirements. He needed someone with a balanced affinity across the five elements, just like himself, someone who could cultivate into a Ten Refinement Earth Monarch.
"This can wait. That kid was kind of interesting."
Yi Tianyun had developed a bit of interest in that bold youngster.
Courage and guts alone made him worth considering as a disciple. Perhaps not a core one, maybe as a registered disciple first.
He didn't demand extraordinary talent. The first requirement was absolute loyalty. Without that, how could he pass on anything? Next came diligence and hard work. Talent came last.
Even a less talented disciple could play an important role in the long run. Not every disciple had to become a genius or surpass him, they could simply be loyal and steady.
Such disciples could still take part in major decisions and planning.
Shifting his attention back to the wall, Yi Tianyun continued his walk along the long corridor. The scenes around him kept shifting, showing various parts of the Three Realms, all functioning smoothly and in order.
In the years since his retreat, everything remained peaceful and united.
Generally speaking, nothing would go wrong unless he'd provoked a serious enemy. Now, he had indeed made enemies, but who would suspect him?
Especially with Heavenly Venerable Slaughter God's death, no one would imagine that Yi Tianyun, from a First-Grade God Territory, could kill a Heavenly Venerable!
As he walked on, he realized just how long the corridor was. It had essentially flattened the Three Realms into a single long hallway, allowing complete surveillance of every detail.
No wonder it felt endless. Even so, Yi Tianyun kept a brisk pace while continuing to scan his surroundings.
"Once your cultivation reaches a certain level, observation rooms like this become pointless. I guess this place is more like a walking path for someone with nothing better to do…"
After all, at the Earth Monarch level, divine sense could scan any corner of the realm at will, visual observation was redundant.
Still, maybe the creator just liked it this way, Yi Tianyun wasn't going to argue.
Before long, he spotted an exit ahead and quickened his pace, shooting through the corridor and emerging on the other side.
What greeted him was a glowing orb of five-colored light, spinning slowly and radiating an endless stream of energy.
Five Elements Core, Sixth-grade core. A super core of extremely rare class. Fused from the five elemental attributes, harmoniously supporting one another. The power it holds is overwhelming. This is the might of the Supreme Five Elements!
"A sixth-grade core... and it's the Supreme Five Elements kind?"
Yi Tianyun gasped. Sixth-grade was already rare, but a core that fused all five elements? That was almost mythical! Single-element cores were rare enough, this multi-elemental fusion was truly unheard of.
He never expected to stumble upon the very location where such a core was housed.
This made him think of the other two cores, were they also Five Elements Cores? At least for this one, there was no doubt, it was the real deal! That meant he could absorb its energy and possibly form his own Five Elements Core through internal fusion.
He already possessed metal, water, and wood attributes, lightning didn't count as one of the five elements. So absorbing this could fill in the missing earth and fire energies.
"This is insane... a Five Elements Core in a single orb…"
He could feel the terrifying energy radiating from it, perhaps even stronger than a Heavenly Venerable. It was so intense he didn't dare get too close, the energy waves alone might obliterate his soul.
Surveying the surroundings, he found nothing else, just the Five Elements Core in the center. No other entrances or features.
Behind the core lay a dead end. That was all.
"Absorb this Five Elements Core, and you will become the true Master of the Mortal World. Simultaneously, two new trial paths will be unlocked."
A line of text suddenly appeared in the void, startling Yi Tianyun. He hadn't realized this was a trial mission. Absorb the core, and you'd become the Mortal World's ruler.
"Ding! Special mission accepted: 'Become the Master of the Mortal World'. Completion reward: Title – 'Mortal World Master'. Grants access to the strongest effects of the Mortal World! No other rewards available."
"So there's a title for that? I thought I already controlled the Mortal World…"
Yi Tianyun was surprised. With his current power, he'd assumed he already held that status.
But upon seeing this Five Elements Core, he realized that true mastery meant possessing this core. The Five Elements Core was the embodiment of the Mortal World's power.
And... there were no extra rewards. Not even experience points?
He was slightly speechless. Such a massive task, and only a title?
Still, he didn't dwell on it. If the reward was this simple, it probably meant the title itself held incredible power, so much so that no extra compensation was necessary.
"The true Master of the Mortal World, huh? Looks like I have to try this."
Eyes lighting up, Yi Tianyun sat down and began absorbing the energy from a distance. If he could draw in its power, he could instantly condense two more elemental cores inside himself. That would meet the requirement of five planetary cores, necessary for breaking through to Heavenly Venerable!
If successful, he would instantly be two steps closer.
Without delay, he began rapidly absorbing the Five Elements Core's power, carefully channeling it into himself. After a period of buffering, he successfully condensed two new core energies, earth and fire!
Two planetary cores formed at once, something truly unprecedented.
"I wonder... what kind of power will I gain after fully absorbing this and becoming the true Master of the Mortal World?"
Yi Tianyun was filled with excitement. If successful, it might be the edge he needed to win the God Territory War. Perhaps only by reaching the Fourth-Grade God Territory level could he truly secure his place.
Even with Heavenly Venerable Li Tian's help, having an extra trump card of his own was always a good idea.
