"Well, Mingde, what do you think is the biggest bottleneck when disguising yourself as someone else?"
In a worn but tidy courtyard, a boy of about eleven or twelve years old was doing push-ups with three fingers on the concrete floor.
Beside the boy, a spirited old man was watering the flowers and plants in the yard.
"Details, background information, habits, and so on... thirty-three, thirty... four..."
The boy thought for a moment and answered casually while continuing his push-up exercise.
"Very close, but not accurate enough."
The old man casually picked up a red spider from a jasmine leaf, crushed it to death, mixed the corpse with mud, and softly said, "Plundered, returned to the original owner," burying the fragments in the soil.
"Is there a better answer?"
In a calm and unhurried tone, the old man asked the boy again.
"Thirty... six, three... seven... huh... I'll say if I feel like it, I'm not interested."
The boy, who was doing push-ups with great effort, refused to answer the old man's further questioning.
"Oh dear, young people are really impatient."
The old man paused, scratched his graying hair, and then sat down next to the boy on the ground.
"The biggest bottleneck is personality."
The old man looked like he had revealed a great secret, but the boy didn't appreciate it or pay any attention. In order to spark the boy's curiosity, the old man had to continue.
"A person cannot completely pretend to be someone else due to the differences in personality. Personality is not just about character, but a complex whole composed of memory, habits, and many other trivial factors, including the mentioned character."
"So even if the appearance is very similar, there will always be some details that give it away."
At this point, the old man intentionally paused and secretly glanced at the boy, hoping to see some hint of interest. However, the boy had just finished his forty push-ups and was lying on the ground, panting, completely indifferent to what the old man had just said.
Helplessly, the old man pretended to cough a few times to cover up his embarrassment.
"To address this fundamental bottleneck, I have been practicing a new skill lately, which I called 'personality forging.' I deliberately construct a completely independent personality in my brain and can switch back and forth between it and my current personality, even transferring it to other bodies!"
After saying these words, the old man eagerly looked at the boy again. However, the boy's reaction left the old man dumbfounded. The old man didn't expect the boy to show any interest; instead, the boy switched hands and started doing one-handed push-ups.
"Mingde, aren't you interested in such an amazing skill?"
"Eleven... twelve... thirteen... Why should I be interested? This has nothing to do with me, and I have no need to pretend to be someone else."
The boy was not polite at all in speaking to the old man, stating his indifference boldly. Hearing this, the old man finally gave up trying to persuade the boy.
"I thought you would be interested..."
Muttering to himself in disappointment, the old man took a final glance at the boy, stood up, patted his bottom, and left.
—Since I can't make him willingly learn, I'll have to use some means.
Beneath his charitable appearance, the old man quickly made a cold decision in his heart.
