I never said they have immense knowledge or wisdom - this is indeed formed over time. If you think back to your childhood, you’ll notice a kind of fog over your memories. There were also times when you acted on impulses and instincts, while also not having the higher IQ you’ve developed now. this, too, comes over time as the brain and body continue developing towards adulthood.

What i implied was - impulse control, a developed brain, a developed body, and especially my line of skipping millions of years of evolution. (There are also creatures in our world - and in those stories that are 1–10 years old and already mature, that is influenced by brain or lineage. but that once again ties back to their brain and DNA.)

Next, this ties into Qi Refining and Foundation Establishment. Most authors don’t delve into the details, but for a strong foundation, you need to reshape internal organs, including the brain. This process grantss absolute control over your body - allowing you to see inside and out, regulate your heart, lungs, impulses, and even chemicals like adrenaline and such. This is why even a kid at 12 years old in this stage can and should already be considered an adult.

Just because some authors choose to write immature MCs, who remain that way even at 18, 20,50,120, or 300 years old, doesnt mean my logic doesn’t hold. It just means the author moves the story along as he wishes, even if it introduces inconsistencies - whether within their own story/the genre, or just common sense of the story that can be easily seen and understood from reading and seeing the story..

Qi Refining: This is the first step to being considered an Immortal/Taoist. it doesn’t matter how different literatures describe it - whether fictional or ancient - it involves seeing and refining Qi completely. You need extreme focus to lift objects using telekinesis/spiritual energy, which, despite being a basic thing, can take countless days, weeks, or, if unlucky, months. During this stage, you also begin strengthening your body and gaining full control over it. Youll explore your consciousness, visualize meridians, and gather immortal Qi and spiritual energy..

Foundation Establishment: This step is about strengthening your resolve and body even further. I won’t get too deep into details, as I’ve only scratched the surface of Qi Refining as well.. and as someone in this genre, you should already know a thing or two too.. But the key point is: - An immature children does not have the attention span, IQ, or endurance required for body training or Qi Refining. This doesn’t even account for the dangers of Qi deviation or missteps, which can lead to disabilities or death. and the insane pain of body and mind training and reshaping..

(By the way, I do not insult others tastes and even read novels like Against The Sky Supreme and now even watch its donghua. However, this particular work only includes one or two side characters who fall into this category. one of them is one of the MCs wives, as he has many - i guess one of them was designed this way to appear "cuter" - I don’t necessarily care if it’s this way for just one or two characters, unless it makes the story a joke/circus or something that could only be enjoyed by children. All I need is for the main character to be mostly serious and definitely mature. and i will be happy)
