Super Fast Progress! (Fourth Update)

"Earth Style: Earth Style Wall!"

Three thick earthen walls suddenly rose from the ground, shielding Ishii Kawa and Gong Yi within.

Even though he had already learned the Three Body Technique and had even managed to develop a bootleg version of the Shadow Clone Technique, Gong Yi was still struck with amazement at the sight of this Ninjutsu that could conjure a wall out of thin air.

Is this the power of Ninjutsu?

Gong Yi had no doubt that relying on these three walls could block any sudden attacks from an enemy.

He thumped the wall; its solid thickness promised excellent defensive capabilities.

Seeing Gong Yi's surprise, Ishii Kawa smiled.

Gong Yi had always been calm and indifferent, rarely showing much emotion, to the point where he seemed as mature as an adult.

Seeing him surprised now made Ishii Kawa feel quite proud.

However, as a teacher, he had to be thorough in his instruction of Ninjutsu.

"Are you a bit disappointed that the first Ninjutsu I'm teaching you isn't an offensive one, Gong Yi?"

Gong Yi pulled his hand away from the wall, his gaze returning to its usual calm.

"No, I think it's great. Compared to how to kill an enemy, preserving one's own life is the most important thing."

"Uh..."

Ishii Kawa gritted his teeth, feeling a slight headache.

This student was a bit too clever for his own good.

He began to explain the function of the Earth Style Wall, the sequence of hand seals, the timing of release, and other key points.

"I joined the battlefield at the end of the Second Great War, so I didn't participate in any of the most intense battles. However, I did encounter some small-scale skirmishes."

"In those small-scale battles, the defensive performance of the Earth Style Wall was exceptional; it saved my life several times."

"The Three Body Technique is too limited. As civilian ninjas, we are very likely to become cannon fodder once war breaks out. With the protection of the Earth Style Wall, your chances of survival will be much higher, Gong Yi. Only then will you have more opportunities to grow stronger."

When he said this, Ishii Kawa's words inevitably carried some personal subjective emotion.

He was also a civilian ninja, though he had managed to avoid the most brutal period of the Second Shinobi World War.

Yet, he still held onto his grievances regarding some of the village's practices.

And he harbored a great deal of resentment!

Gong Yi listened quietly, offering no opinion.

Ishii Kawa sighed, stopped talking, and turned to explain the hand seal sequence for this simple C-rank Ninjutsu.

"As a C-rank Ninjutsu, the seals aren't complicated: Rat, Ox, Monkey, Boar, Bird. Five movements in total. If you practice, you can release it quickly."

"You've had a practical training session today and must be tired, so get some rest early! If you have any questions, ask me later."

Ishii Kawa left, but Gong Yi did not rest.

He cast a Recovery Technique on himself, then walked home slowly, recalling the details of Ishii Kawa's lesson on the Earth Style Wall in his mind.

After arriving home, Gong Yi sat in meditation for ten minutes, then opened his eyes and went to an open space.

His slender fingers began to move, forming the seals slowly in the order of Rat, Ox, Monkey, Boar, Bird.

Once the seals were complete, Gong Yi slammed his palm onto the ground and gave a low shout.

Earth Style: Earth Style Wall!

Chakra surged out, the ground trembled slightly, and then a small mound of earth popped up.

A failure?

The corners of Gong Yi's mouth curled up; in his view, this was already a success.

The practice of any Ninjutsu is built up bit by bit. Since he had created a small mound on his first try, the next time would be even better.

In the days that followed, aside from his daily exercises, Gong Yi added a new training item.

That was the practice of the Earth Style Wall!

From the initial small mound to a fragile wall a few days later, and finally to a solid, sturdy wall after ten days, everything proceeded according to Gong Yi's plan.

One evening, Gong Yi stood before a two-meter-high wall, lost in thought.

"With the same Ninjutsu, Teacher Ishii can release three walls, and their defensive performance is equally excellent. Yet I can only release one?"

Frowning, Gong Yi touched the wall he had created.

In terms of thickness and hardness, it was actually no weaker than the wall created by Ishii Kawa, a Chunin.

If Ishii Kawa had been keeping an eye on Gong Yi during this time, he would likely have been incredibly shocked.

Even for a C-rank Ninjutsu with simple seals like the Earth Style Wall, mastering it in just ten days was enough to stun anyone.

However, Gong Yi didn't feel much pride.

He knew his own situation best.

The benefits brought to him by the Scholar System and its Recovery Technique were not as simple as most people thought.

It is common knowledge that the cultivation of Ninjutsu requires the constant expenditure of chakra.

A person's chakra storage capacity is very limited; once exhausted, one must spend time refining more before they can continue practicing Ninjutsu.

However, the Recovery Technique allows Gong Yi to bypass this process, enabling him to cast Ninjutsu without interruption!

If an average Genin can cast a C-rank Ninjutsu twenty times a day, then Gong Yi's capacity is ten, or even a hundred times that baseline!

It is precisely for this reason that Gong Yi was able to master this Ninjutsu so quickly.

Of course, this sounds wonderful, as if Gong Yi possesses infinite chakra.

But in reality, it is not that broken.

He only saves the time required for chakra recovery; his overall chakra capacity has not increased!

To put it simply!

Gong Yi can use the Recovery Technique to continuously cast C-rank Ninjutsu, and due to his physical and spiritual energy, he even has the chance to cast B-rank Ninjutsu.

However, his chakra ceiling makes it very difficult for him to fully cast an A-rank, or even an S-rank Ninjutsu.

The Recovery Technique also requires several minutes to perform, but the casting of a high-level Ninjutsu will not grant you the opportunity to pause midway, recover, and then continue forming hand seals.

Gong Yi sighed; he roughly understood the reason behind the discrepancy between him creating one wall and Ishii Kawa creating three.

He is a veteran Chunin, his chakra capacity is simply greater than mine, that's all.

Gong Yi bit his lip; this problem is not limited to just the Earth Style Wall Ninjutsu.

He will likely encounter this same issue when practicing other high-level Ninjutsu in the future.

So, how to solve it?

Gong Yi quickly found the direction.

"Bloodline! Tailed Beasts! Sage Mode! Superhuman physique!"
