Chapter 149: Super-Strength Girl Rin
In the South Border Forest, Mugetsu was conducting his daily lesson.
"Rin, if you were teamed with Obito and Guy, what would your role be?" Mugetsu asked.
"To heal them when they're injured… and to protect myself during battle," Rin replied.
"Actually, medical-nin aren't without combat capabilities. You know Lady Tsunade, one of the Sannin, right?" Mugetsu continued.
"Yes. I also want to become an excellent medical-nin like Lady Tsunade," Rin said, her eyes filled with longing.
It might be hard to name the most popular male ninja in Konoha, but when it came to female ninja, Tsunade reigned supreme. She had fans among both men and women, and Rin was one of them. She admired Tsunade's ability to heal while standing her ground in battle.
"As long as you train hard, it's possible," Mugetsu said with an encouraging smile. "Excellent medical-nin can possess incredible combat power. The higher their medical ninjutsu level, the stronger their fighting ability will be."
He then led Rin to a large tree.
"Chakra Scalpel."
Chakra gathered in his hand, sharpened through precise shape transformation. With a light swing—
Boom!
The tree was cleanly severed.
"Amazing! Is this also medical ninjutsu?" Rin covered her mouth in surprise.
When she saw the cross-section of the trunk, her eyes widened further—it was smooth and even, nothing like a normal cut.
"Yes," Mugetsu explained. "This is the A-rank medical ninjutsu, Chakra Scalpel. It's an advanced technique that requires solid mastery of medical ninjutsu to learn."
Next, he demonstrated on a stone. The hard rock split cleanly in two, as if it were tofu.
"Are we going to practice this next?" Rin asked, hopeful.
"Not yet. Your medical ninjutsu knowledge isn't enough to master it right now," Mugetsu shook his head.
"I understand," Rin said, a little disappointed—but her determination only grew. If she could learn such a technique, she'd have formidable combat power.
"What I'm going to teach you now can also boost your strength—perhaps even more importantly," Mugetsu said.
He walked over to a tree even larger than the one he had just cut and, with a burst of chakra, kicked it.
Boom!
The trunk snapped cleanly, crashing to the ground. He then kicked the earth, and the ground within four meters cracked apart.
Obito, training nearby, kept glancing over at the noise.
"Is this taijutsu?" Rin asked uncertainly.
"Yes, but its destructive power doesn't come from raw strength—it's from a special chakra technique called Monstrous Strength," Mugetsu said.
He was using the Pain Sky Foot technique he'd acquired earlier. Whether applied with hands or feet, Monstrous Strength relied on chakra control.
Although Rin's medical training was still in its early stages, her chakra control was already promising. That's why Mugetsu chose to teach her Monstrous Strength first, rather than Chakra Scalpel.
"If someone already had great physical strength and learned Monstrous Strength, wouldn't that make them unstoppable? I think Guy would be perfect for it," Obito said, walking over.
"No. Guy's chakra control is too poor—he can't learn it," Mugetsu replied. "If he tried to learn both the Eight Gates and Monstrous Strength, he'd master the Eight Gates first, and might even open several gates before ever succeeding with this."
For that reason, Mugetsu didn't bother teaching it to Guy—it would be a waste of time, especially since Monstrous Strength couldn't be used after opening the Eight Gates.
"Among you, only Shisui and Rin can learn Monstrous Strength," Mugetsu continued. "But Shisui doesn't need it."
Obito nodded in understanding. Guy struggled with even simple techniques like Shadow Clone, so this made sense.
As Mugetsu expected, Rin picked it up quickly. She couldn't yet shatter the ground like him, but before long she could punch through a normal tree with ease.
"Such strength!" Obito gaped, his mouth wide enough to fit a duck egg, watching Rin's slender arms deliver such power.
"Don't underestimate a medical-nin," Rin said with a gentle smile, pulling back her fist.
Obito thought to himself—how could he? A punch like that could shatter bones.
"Hehe, Rin, in the next practical exam, you'll definitely scare everyone," Obito said, happy for her.
Mugetsu nodded in approval. To prevent Obito from falling into darkness, Rin needed to grow stronger—strong enough never to be a burden.
According to his training plan, by the time Rin turned twelve, she would have mastered advanced medical ninjutsu like Mystical Palm Technique and Chakra Scalpel. With Monstrous Strength and Chakra Scalpel, she could attack fiercely or retreat to heal allies.
(It's a pity she's not my disciple. This would be the perfect time to trigger the improvement reward, Mugetsu thought.)
Since he wasn't sure if he'd get new disciple slots in the future, Mugetsu guarded his last one carefully. Early on, it might not seem important, but during rapid growth, the difference in master-disciple feedback between talents could be enormous.
[For example: At Trust Level Four, if a talented disciple gained 1,000 chakra in a month, Mugetsu would gain 4,000. But if the disciple only gained 300 chakra, Mugetsu would get just 1,200.]
Right now, his greatest wish was to take on an Uzumaki clan disciple—but the opportunity wasn't there. The only Uzumaki he had contact with was Kushina, but she was already grown. Even with her chakra suppressing the Tailed Beast, she was still appraised at 150,000 chakra.
