Efficiency Soars

In adjusting the Bright Virtue Method, Kamiya Keiyun added a process for exploring the meridians rather than blindly shaping them.

If the meridians were too small, Chakra could be controlled more precisely and guided into them. Of course, he could also use the meridians to expand the meridians—gradually rubbing against them, then widening them once enough progress had been made. That was another method.

To better match the feel of qi cultivation, Kamiya Keiyun renamed the Bright Virtue Method the Bright Virtue Qi Cultivation Technique!

The Pure Tranquil White Lotus Sutra did not need changing. Like a passive skill, it remained in effect at all times and worked quite well. Kamiya Keiyun could feel his senses growing sharper by the day, to the point where he could even sense the Third Hokage observing him.

"Right, since Shadow Clones can transmit memories, can't I have one practice some ninjutsu for me?" Kamiya Keiyun thought of something else. He could have a clone handle things like digging tunnels too!

He immediately created a clone and said, "Try using the [Pipe Technique] in whatever way feels most natural to you."

He discovered that the Mud to Stone Technique should be a broad category of ninjutsu. It could branch into various techniques, such as the Pipe Technique, Brick Technique, Beaker Technique, Flask Technique, Test Tube Technique, and so on.

Calling them all [Mud to Stone] would make things unclear.

Ninjutsu would need to be categorized in the future, but Kamiya Keiyun did not know many techniques yet, so there was no rush.

"Alright!" A clone was his best helper, because it possessed the same memories and the same thoughts as him.

Kamiya Keiyun thought of a scientist from One Punch Man who had cloned himself. When he had been alone, his research output had been limited. But once he had clones, he immediately stopped acting human—not only did he start making artificial humans, he could even create Dragon-level monsters.

The Shadow Clone Technique had that kind of potential too.

Unfortunately, Kamiya Keiyun's Chakra reserves were still too low, so he could only create one clone.

"Can I change my appearance?" the Shadow Clone asked.

"Uh, why do you want to change your appearance?" Kamiya Keiyun asked.

"Uh, isn't making an alt account and changing your identity perfectly normal?" the Shadow Clone replied as if it were obvious.

"Ah, right." Kamiya Keiyun was somewhat speechless. That actually makes a lot of sense. The me on Bilibili, the me on Weibo, the me on Hupu, the me on Zuiyou, the me on Zhihu—they really don't look like the same person either.

"Do whatever you want," Kamiya Keiyun said.

Bang! The Shadow Clone formed hand seals and used the Transformation Technique, becoming a civil engineering graduate wearing blue work clothes and an orange hard hat.

"From today onward, call me Kamiya Ishiku!" the Shadow Clone declared.

"Fine, but when you just used the Transformation Technique, did you feel anything unusual? About your Chakra?" Kamiya Keiyun asked.

"Uh, it seems like it used very little Chakra?" Kamiya Ishiku thought about it. The Transformation Technique inherently consumed very little Chakra, so the difference was not very obvious.

He simply went into the tunnel and used a more Chakra-intensive technique: the Rock Pipe Technique!

Boom! In an instant, a twelve-meter-long rock pipe was carved out.

Kamiya Ishiku froze for a moment, then shouted excitedly, "Holy crap! This Chakra consumption produces twice the original result, but only uses one-third as much! In other words, the same amount of Chakra produces six times the effect when used through a Shadow Clone Technique!!"

"That's perfectly normal. Your Shadow Clone body has no meridians, like a circuit with no resistance—it's become a superconductor. Naturally, one hundred percent of the current can be used by the appliance, and ninjutsu is that appliance!" Kamiya Keiyun was excited. "That means you have half my Chakra reserves, but your daily workload is three times mine! You can dig sixty meters in one go!"

"As expected, science is the primary productive force!"

Kamiya Ishiku nodded in agreement, then added, "Right, give Hei Bei to me!"

"What do you need him for? He's much less efficient than you," Kamiya Keiyun said.

"He can't dig large pipes, but smaller ones should be fine. I want him to dig some light shafts. It's really too dark down there!!" Kamiya Ishiku said.

"Alright! Go find him yourself. He should be upstairs in class. If you can, teach him to recognize some words while you're at it!" Kamiya Keiyun nodded. He had originally found Hei Bei to dig tunnels, but now that he had Kamiya Ishiku, Hei Bei was naturally no longer needed.

Since Kamiya Ishiku wanted him, he could have him!

Meanwhile, Kamiya Keiyun checked his own Chakra reserves.

As he absorbed food, his Chakra slowly recovered. At this rate, it would be fully restored in about six hours.

Then he could create another Shadow Clone!

By then, Kamiya Ishiku would have nearly exhausted his Chakra and dispersed, so Kamiya Keiyun could simply summon him again and have him continue working.

In other words, he could work four times a day, digging sixty meters each time—for a total of two hundred and forty meters per day!

Kamiya Keiyun's total planned project was 100 + 100 + 400 = 600 meters. It would only take three days to finish!

"Hmm?" Kamiya Keiyun suddenly realized that time seemed to be running short!

He hurried upstairs and entered the Training Room.

Inside the Training Room, Sanyō and Ruri were diligently refining Chakra.

"Ruri, how is your Transformation Technique coming along?" Kamiya Keiyun asked.

"I can transform into something fifty centimeters tall now!" Ruri replied.

"From now on, stay with me. I'll continuously teach you a better Transformation Technique!" Kamiya Keiyun said.

"Ah!" Ruri excitedly sat up. "Yes, yes!"

The efficiency of Kamiya Keiyun teaching her personally was far too high. It was much more efficient than trying to figure things out by herself!

"Also, when class starts the day after tomorrow, I'll take you to the classroom. Hide inside my clothes and don't make a sound. Then I'll introduce you to everyone in the class," Kamiya Keiyun continued.

"Ah, so... what do you want me to do? Pretend to be you?" Ruri finally came to her senses.

"That's right. I need to leave the village for a while, and I don't know when I'll return. Shadow Clones can't go too far from the original body, so I can only have you attend class in my place!" Kamiya Keiyun said.

"Can... can I do that?" Ruri trembled nervously. "What if I'm discovered? I'm only a kitty!"

"What are you afraid of? The Ninja Academy only started a few days ago, so the lessons haven't progressed far at all. I'll teach you for three days, and that'll be enough for you to catch up. I don't interact with people much at school anyway. Once you get there, you can sleep from morning to night! The current classes are all first-year courses, and there are no combat classes yet. You don't need to worry about the Transformation Technique failing at all!"

"Then..." Ruri nodded. Put that way, it really did not seem like there would be any problem.

"Then it's settled!" Kamiya Keiyun said, pulling out a copy of Land of Fire Elementary Reader 500 Characters. "We'll start with this book!"

The Transformation Technique had requirements for body size, but they were not absolute.

Naruto could not transform into the Nine-Tails by himself, but he could when he transformed together with a toad.

But Naruto, still just a child, could use the Transformation Technique to become an adult woman—the Sexy Jutsu.
