This ninja in Naruto is unscientific

After a short rest, the hermit Fukasaku began preparing the Two Lives Technique for Nishikawa Tetsu.

"Konishikawa Tetsu, although you are already able to maintain perfect balance on your own, the point of the Two Lives Technique is not to make you relearn Sage Mode."

Fukasaku explained, "You must adapt to continuously receiving natural energy outside your body, while also maintaining your mobility and combat abilities."

"clear."

Nishikawa Tetsu nodded.

"Simply put, it's about using the two immortals as external charging devices."

"They are companions," Fukasaku the Hermit corrected.

"Functionally, it is an external charging device."

"Konishikawa Toru!"

"Good, good, good, it's a reliable Toad Sage Art synergy module."

Master Shima walked over from a short distance and happened to hear those words.

"I think you should just absorb natural energy on your own."

"No, Master Shima," Nishikawa Tetsu quickly said, "I was just trying to make it easier to understand, wasn't I?"

"You're calling us equipment; who wants to sit on your shoulders?"

"I can provide nutritional supplements."

Master Shima stopped in his tracks.

"What flavor?"

"Any flavor except durian is fine, and we can also customize flavors."

The biggest consumer of the durian flavor recently is Manda. The entire research institute has reserved this flavor from Manda. This is the condition that Nishikawa Tetsu asked it to take him to Ryuchi Cave to study Sage Mode.

"Deal!" Shima immediately agreed. He couldn't miss this opportunity to customize the flavor.

Nishikawa Tetsu brought fruit flavors, not that fruit flavors are bad, but she also wanted to try the insect flavor.

The immortal covered his face.

He suddenly realized that the transmission of immortal techniques from Mount Myōboku was developing in a very strange direction.

A moment later, Nishikawa Tetsu sat cross-legged on the edge of the shallows, his hands forming a mudra.

Fukasaku and Shima transformed into two wisps of white smoke, appearing on his left and right shoulders respectively.

"Celestial Art: Twin Life Technique!"

As the technique was completed, the surrounding natural energy began to converge on Nishikawa Tetsuya at a more stable rate.

The two sages simultaneously channeled their chakra, helping him convert natural energy into stable sage chakra.

Nishikawa Tetsu felt a slight weight on his shoulders, and two new channels for continuous energy input immediately appeared in his body, which were originally required to maintain their own energy balance.

"Input efficiency has improved significantly."

He said it instinctively.

"Much more stable than absorption alone."

"Of course," said Shima, the hermit, proudly. "We are the hermits of Mount Myōboku."

"If we record this process as a curve—"

"Don't draw us as lines!"

"I can draw it as two high-precision magic auxiliary modules."

"Konishikawa Toru!"

Just then, the sound of a water gate came from the side.

"Che, I'm going to start the second time."

Nishikawa Tetsu opened his eyes.

Although he had two immortals hanging on his shoulders, he still held the black staff in his hand very steadily.

"Okay, continue."

Minato sat up straight and adjusted his breathing according to the method that Fukasaku had taught him.

Nishikawa Tetsu felt the chakra input from the Two Lives Technique while observing Minato's changes.

"Slow down the rate of natural energy input this time."

"understood."

"Physical energy and mental energy should be kept in sync."

"Um."

"Don't get nervous just because I'm holding a stick."

"Could you put the stick down first?"

"cannot."

Why?

Nishikawa Tetsu smiled brightly.

"Because there aren't many opportunities to beat you up openly and honestly."

Minato took a deep breath and decided to ignore this person for the time being.

This time, he was indeed in much better condition than before.

The frog-like markings only appeared on the edges of his cheeks and did not spread further. Natural energy flowed slowly within his body, gradually merging with his own chakra.

ten seconds.

Twenty seconds.

Thirty seconds.

Minato's breathing became heavy, and sweat trickled down his face.

Nishikawa Tetsu didn't make a sound to disturb him, but just stared at the changes in the frog-like markings on his face.

Until a layer of light green skin texture suddenly appeared on the fingertips of Minato's left hand.

Nishikawa Tetsu raised the black stick.

"Don't move."

Minato gritted his teeth and maintained his posture.

"I can still hold on."

"I know."

"Then put the stick down."

"no."

"Are you going to hit me again?"

"No," Nishikawa Tetsu said seriously, "I just raised the stick in advance to avoid wasting time when it was actually time to hit."

Minato felt that coming to Mount Myoboku to learn Sage Mode today might have been a mistake.

But in the instant he was distracted, the frog-like growth on his fingers spread a little further to the back of his hand.

"Snapped!"

The black stick fell again.

The natural energy was forcibly dispelled, and Minato fell backward, lying on the edge of the shallows, panting heavily.

Nishikawa Tetsu put away the black stick with satisfaction.

"I held the position for over forty seconds this time, which is a significant improvement over before."

Minato lay on the ground, weakly raising his hand.

"Can't you show some concern for me first?"

"Of course I care."

"Is your concern just hitting me with a stick?"

"This is called stopping in time, preventing you from becoming a stone frog."

"Then you should at least have told me in advance."

"If I told you in advance, you would definitely get distracted."

Minato remained silent.

He found himself unable to refute it.

Fukasaku the Hermit came over and checked Minato's condition. After confirming that there were no problems, he was relieved.

"Minato, you've done a great job holding on to this level today."

"Really?"

Minato sat up, his fighting spirit rekindled in his eyes.

"Um."

Fukasaku nodded, "That's right, these two guys are cultivating faster than Jiraiya."

"If you keep practicing, you will definitely be able to master Sage Mode."

"Did you hear that?"

Nishikawa Tetsu patted Minato on the shoulder.

"Even the hermit Fukasaku says you have hope."

Minato looked at him.

"Then can you please stop using the guise of supervision to hit me?"

"That depends on how fast you transform into a frog."

Nishikawa Tetsu sat back down on the edge of the shallows, with Fukasaku and Shima on his shoulders continuing to absorb natural energy for him.

Not far away, Minato wiped away his sweat and began his training once again.

The afternoon at Mount Myoboku passed peacefully amidst the croaking of toads, the flow of natural energy, and the crisp sound of black sticks falling.

As for the operation of Konoha Express on its first day of official business, Nishikawa Tetsu decided to wait until he returned to the village to see how it went.

After all, he had something much more important to do today—to supervise Minato!
