That was Nihilego's home, and the most dangerous place in all of Ultra Space.
Unlike other Ultra Beasts, which excelled at attacking and destruction, Nihilego were different.
They were intelligent parasitic life-forms with powerful neurotoxins, surviving by attaching themselves to Pokémon or humans.
They possessed survival instincts, but whether they had thoughts and emotions remained unknown. They were among the most dangerous Ultra Beasts.
"Even if we catch the Champion Class Nihilego, we'll still need to come back regularly to clear this place out. These Ultra Beasts are far too dangerous," Xuan Yuan Nian said as they walked through the Ultra Deep Sea.
The Nihilego looked harmless now, but Jiang Cheng had nearly fallen under one's control earlier. Without the powerful perception granted by Xiao Ran's Immortal Power, Jiang Cheng might already have been carried off. Not even her Psychic Power or Veranica's had detected it.
"Once we've cleared out the Ultra Deep Sea, let's head back to Earth first. We're running low on Beast Balls!" Xiao Ran said helplessly after checking the supply in his backpack.
They had brought a hundred Beast Balls with them, averaging ten per person, but they had almost exhausted their supply after clearing just over half of the Ultra Deep Sea.
The Ultra Beasts were truly powerful. They dared not leave even the slightly stronger ones here, and had taken away practically every Ultra Beast at the Late Stage of Elite Four Class.

Thoroughly clearing every region of Ultra Space was no different from land reclamation. Such work usually required many Pokémon Trainers working together. With only ten of them, who knew how long it would take?
"You're right.
