I can imagine that author of this shitshow simply doesn't give a damn about what he's drawing. This cringy, idiotic story about 3 year's old doing philosophical speeches (at least he tries) that somehow works really makes me wonder why I still read this. I am a masochist? I don't know, did mangaka thought that this bullshit is better than how they did it in WN?
WN: Let's check slaves -> Oh, this slave is Magic genius -> Purchasing -> New vassal acquired
Simple, and clean, but no, it would be boring and my manga can't be boring, so let's make rebellious slave story, but copy paste all events without reason in convenient moments (first slavers encounter, sudden kids appearance right after that, kids running to main hero for help even if they knew him for less than five minutes and didn't had any idea who he is, not to mention that he is younger than them ) deprave it of any sense and insert "deep" dialogues between 3 and 11 year old kids that can be summarized: slavery bad. Nobles bad. I'm noble, I'm bad.
Sorry, I had to vent up. Maybe real value of Isekai's stories is in commenting about how stupid they are?
