"Wow—" Karin was utterly stunned. She had never seen such a method of training before.
Naruto used the Multiple Shadow Clone Technique, creating a large number of shadow clones.
Naruto's shadow clones began searching for suitable places to train.
Fortunately, the Uzumaki Clan estate covered an enormous area, with plenty of interior space and multiple separate rooms.
Every corner and every room of the estate was occupied by Naruto's shadow clones.
Seeing Naruto everywhere, with a Naruto in every corner, Karin was completely dumbfounded.
Naruto had devoted all his thoughts to training, wholeheartedly practicing the Flying Thunder God Technique.
"Are all men this boring?" Karin sat on the floor in boredom, watching Narutos diligently training everywhere, unsure what she should do for the moment.
"Release!" Naruto dispelled the Multiple Shadow Clone Technique, and an overwhelming wave of exhaustion hit him.
His eyelids became incredibly heavy. He instantly lost his balance, his legs gave out, and he collapsed straight onto the floor.
Naruto gritted his teeth and stood up, then dragged his heavy steps over to Karin.
Seeing Naruto's pitiful appearance, Karin rolled up her sleeve and revealed an arm covered in bite marks.
Naruto bit down on Karin's arm. As if that was not enough, he gradually increased the force of his bite.
"Ah—" Karin cried out. She could not describe the feeling with words. It hurt, yet she did not resist.
Karin pouted, thinking, He said he would be gentle before, but he's just like everyone else. Once he starts biting, he uses all his strength...
With that bite, Naruto instantly recovered his energy and became full of vigor.
"Multiple Shadow Clone Technique!"
Naruto collapsed from exhaustion and bit Karin once.
"Multiple Shadow Clone Technique!"
Naruto collapsed from exhaustion again and bit Karin another time.
"Multiple Shadow Clone Technique!"
