"Kushina!" Minato quickly found Kushina. She had just come out of the Uchiha Clan Territory, her face still flushed with excitement.
"Minato! That kid Uchiha Chuan is really amazing, a total genius, you know?" The moment she saw Minato approach, Kushina immediately began chattering away, her voice full of excitement.
"You know the Loudspeaker Technique, right? Uchiha Chuan actually solidified it into a physical loudspeaker! And after it became physical, none of the Loudspeaker Technique's properties changed at all! You heard it just now too—I used it to broadcast the recruitment notice to all of Konoha! It's way faster than putting up flyers or anything like that!" Kushina said excitedly, her eyes sparkling.
"He solidified a loudspeaker ninjutsu into an actual loudspeaker?" Minato, who had been wearing a wry smile, stared in disbelief after hearing Kushina's words. In an instant, he threw all his previous concerns aside. Right now, he was simply a ninjutsu enthusiast and researcher facing an astonishing technique. "Can something like that really be done?"
"Hahaha, I bet my expression back then looked just like yours does now, Minato! I didn't believe something like that was possible either, but Uchiha Chuan actually did it!" Kushina said with a laugh, a hint of pride in her voice.
"And he even told me the principle behind it! He said every ninjutsu actually has its own fixed imprint. We copy that imprint, then reinforce it onto a Shadow Clone. That gives us the ninjutsu imprint of a physical Shadow Clone, and that counts as successful solidification! Then, whatever form we need, we just turn the Shadow Clone into that form!" Kushina continued explaining, her voice brimming with excitement.
"This... it sounds like it makes a little sense, but it also sounds completely unreliable." Minato looked utterly baffled after hearing it.
