After listening to Volcarona's explanation, Yuga finally understood why Cofagrigus contained such vast life energy and why there was a human skeleton within its body. He also realized why his Insight ability didn't affect it. While its situation was different from Muya's, there were similarities.
"Now that Cofagrigus is gone, you don't need to guard this place anymore. Have you thought about what you'll do next?" Yuga asked Volcarona.
The Unown that responsible for sealing Cofagrigus had disappeared when the magic circle shattered.
Volcarona shook its head, indicating that it didn't know. It had been guarding Cofagrigus's seal since its birth, and now that the task was over, it was unsure of its next steps.
At this moment, Yuga heard the system's voice in his mind.
[ Congratulations, Host, on triggering the task: Taming Volcarona. ]
[ Explanation: Powerful Pokémon are every trainer's desire, and a formidable Volcarona is right in front of you. What are you waiting for? ]
[ Reward: A Fire Stone vein. ]
Yuga was startled by the sudden task announcement and its extravagant reward. Could it be that taming an Elite level Pokémon like Volcarona was that straightforward? And a Fire Stone vein as a reward? That seemed excessive.
Seeing Volcarona's uncertain gaze, Yuga cautiously asked, "Do you want to follow me? After all, you don't know where to go now."
To Yuga's surprise, Volcarona tilted its head in thought and then nodded.
Volcarona had rarely left this ruins since birth. While it was powerful, it had limited exposure to the world, making it easy for it to agree to Yuga's proposal.
Yuga had resolved Volcarona's issue with Cofagrigus, granting it freedom. This act had earned Yuga significant goodwill from Volcarona. Moreover, Yuga possessed formidable strength, with powerful Pokémon like Noctowl, Gengar, and Mismagius by his side, so joining him seemed like a reasonable choice for Volcarona.
Seeing Volcarona's nod, Yuga was overjoyed. He didn't expect Volcarona was easy to be "abducted".
Yuga took out a Poké Ball, and capturing Volcarona was surprisingly smooth. As soon as he tamed Volcarona, the system notified Yuga that he had completed the task.

While Volcarona's move set consisted mainly of Bug and Fire-type moves, its strength was undeniable.
With Volcarona now under control, Yuga turned his attention to Chandelure and asked, "What do you plan to do?"
Chandelure pointed towards Yuga's Shadow Space, indicating its desire to enter. The energy that had leaked from Yuga's Shadow Space had left Chandelure drooling.
Yuga sighed, "To live inside my Shadow Space, you need to be one of my Pokémon."
Chandelure promptly nodded, showing no hesitation. But after nodding, it seemed conflicted.
Seeing Chandelure's change of demeanor, Yuga furrowed his brow and asked, "What's wrong?"
Chandelure then expressed its concerns. It was worried about leaving its subordinates here without anyone to care for them.
Yuga smiled, reassuring Chandelure that there was nothing to worry about. Chandelure's subordinates could easily join it. If Yuga won the opportunity to establish a Gym, he would gain two new Sub-Ecopark. He could choose one suitable for Ghost-type Pokémon and relocate them there.
Yuga explained his plans to Chandelure, who no longer had any concerns and happily entered Yuga's Shadow Space.
Gengar and Mismagius, having absorbed a significant amount of life energy and leveled up, were now asleep within Yuga's Shadow Space while Marlon and the others remained unconscious.
Taking advantage of their unconsciousness, Yuga, along with Chandelure, transferred Chandelure's subordinates into Yuga's Shadow Space before Marlon and the others woke up.
Yuga checked on Marlon and the group. Although they had absorbed some life force from Cofagrigus due to the brief encounter, it hadn't caused significant harm. They needed some rest to recover fully.
Chandelure's subordinates were all Litwicks, there's no Lampent itself, totaling over a hundred. Fortunately, Gengar and Mismagius were asleep; otherwise, they wouldn't have allowed so many Pokémon into Yuga's Shadow Space.
With Chandelure's assistance, Yuga efficiently relocated all the Litwicks.
Volcarona saw that after Yuga had taken away the subordinates of Chandelure, he asked Yuga to take away its subordinates, Darmanitan and Darumaka, as well.
As for Cofagrigus minions that had been battling Darmanitan and Darumaka, Volcarona took care of them effortlessly. Yuga had no intention of taming them; even though they didn't drain life energy from others, being under a Shiny Cofagrigus's command made them unpredictable.
Once everything was in order, Yuga used a Poké Ball to capture the weakened Yamask, who was on the brink of fading away due to its damaged core. Like Muya before, it would gradually dissipate.
With everything settled, Yuga gathered Marlon and the group, including their Pokémon, in one place. Even the incapacitated Chimecho received treatment from Florges using a Grassy Terrain.
Despite the perilous journey, Yuga's gains were substantial: an Elite level Volcarona, a pseudo-Elite level Chandelure, Darmanitan, Darumaka, and many Litwicks.
However, Marlon and the others didn't fare as well. They had fainted shortly after entering the area. Yuga didn't intend to tell them about defeating Cofagrigus and capturing Volcarona; they were best left unaware.
Volcarona had informed Yuga that this location was originally the tomb of a small kingdom's king, so it likely contained various burial treasures. When Marlon and the others woke up, they wouldn't leave empty-handed.
These burial treasures held significant value and would surely bring satisfaction to Marlon and the rest.
With Florges' healing, Marlon and the group woke up shortly.
Brawly rubbed his head and sat up, glancing at Yuga and then around, puzzled. "What's going on? Where's Cofagrigus? What about Volcarona?"
The others also looked at Yuga with confusion.
Yuga patted his own head, pretending to have just awakened. "I don't know either. I woke up not long ago, just like you. I assume that Volcarona dealt with Cofagrigus."
Marlon and the others didn't doubt him; after all, they didn't believe Yuga had the capability to handle Cofagrigus and Volcarona. The most plausible explanation was that Volcarona defeated Cofagrigus and left. If Cofagrigus had won, it wouldn't have spared them.
