On Akala Island,
Olivia had said that Rockruff was about to evolve and suggested that Ash and the others stay another day.
So they decided to spend one more day on Akala Island to witness Rockruff's evolution.
After discussing it with Professor Kukui, Li Wei agreed as well. They had nothing to do tomorrow anyway.
Ash's Rockruff would almost certainly evolve into a Dusk Form Lycanroc.
How did Li Wei know?
Aside from what he remembered,
it was really thanks to his Appraisal Eye.
When Li Wei used his Appraisal Eye on an ordinary Rockruff,
[Name]: Rockruff [Type]: Rock-type [Ability]: Keen Eye / Vital Spirit / Steadfast (Hidden Ability) [Moves]: ...
that was basically what he saw.
But Ash's Rockruff was different.
[Name]: Special Rockruff. [Type]: Rock-type [Ability]: Own Tempo (Its independent nature prevents it from becoming confused.)
There was nothing subtle about what made this Rockruff special.
That was why Li Wei was certain this special Rockruff would evolve into a Dusk Form Lycanroc.
Ash really was something special.
Li Wei kept packs of Rockruff at the Theme Park. Even if there weren't a hundred, there were at least sixty or seventy.
These Rockruff would gradually be sent to other regions. They could serve as police dogs or be given to new Trainers as their Pokémon.
But the Rockruff at the Theme Park were all ordinary Rockruff and could only evolve into Midday or Midnight Form.
Professor Kukui decided to stay and watch, but Li Wei wasn't particularly interested and returned to the Theme Park.
Pokédex Rotom would record the evolution anyway, so Li Wei could watch it later.
That night,
Pikachu nudged Ash, who was sound asleep.
"Pika..."
Ash suddenly realized that Rockruff was gone.
"Come on, Pikachu! Let's go find Rockruff!"
