Chu Xin ignored Chen Huan and handed Slowpoke the King's Rock Chen Huan had given him.
"I've brought you your King's Blade, but if you want to use it, you have to tell me beforehand. Luo Luo and I need to plan out your future growth."
After handing Slowpoke the King's Rock, Chu Xin gave it a very serious warning. He could already tell that the Slowpoke he had caught was very different from ordinary Slowpoke. It surprised him in all sorts of ways, not just in battle.
And Slowpoke actually knew about an important item like the King's Rock. At this point, even if Slowpoke told him it could evolve using the King's Rock, Chu Xin would no longer be surprised.
Chu Xin had previously been torn over which evolution path Slowpoke should take. Now that Slowpoke had asked him for and received the King's Rock, it seemed its choice was to evolve into Slowking.
That was something of a relief for Chu Xin. If it evolved into Slowbro, he would have to figure out where to find a Mega Evolution Stone for it. Now that Slowpoke had decided to evolve into Slowking, he could skip that step.
Chu Xin's warning wasn't meant to hinder Slowpoke's growth, but to help it. For a Pokémon like Slowpoke, whose evolution had no level requirement, prematurely using an item to evolve into Slowking before it was ready would be an enormous waste of its potential.
Every stage before a Pokémon's final evolution was a period of storing up energy. The stronger the Pokémon, the more time and effort each of those stages required. Take Dragon-type Pokémon, widely recognized as powerful in the Pokémon world: most went through a long period of weakness before reaching their final forms. The stronger they trained themselves
