Battle Against the Protagonist Class

Half a month later.

By the river in the forest.

"Fire Style: Great Fireball Technique!" Su Yu said while forming hand seals.

The next second.

A massive fireball erupted, landing on the surface of the water.

Until the fireball vanished.

Su Yu nodded in satisfaction.

A mastery-level Great Fireball Technique was enough.

Over these past half a month.

In terms of taijutsu, he made progress every day.

In terms of ninjutsu, he had learned all three techniques, and all of them had reached the mastery level.

That is to say, he possessed a certain degree of proficiency.

Great Fireball Technique, Water Prison Technique, and Rasengan.

To be honest, he was indeed surprised when he saw the training method for the Rasengan.

However, after giving it a little thought, he understood the Third Hokage's intentions.

His parents were Anbu under the Hokage's direct command, and he had been promoted to Anbu Chunin at such a rapid pace.

Giving him the Rasengan was both compensation and a reward from the Hokage.

It took Su Yu one week to master the Rasengan.

The Great Fireball Technique and Water Prison Technique—one an offensive ninjutsu, the other a control-type—were not that difficult to learn.

The hardest to learn were the sealing techniques and medical ninjutsu.

The sealing technique also gave him a surprise.

Because the name of this sealing technique was Adamantine Sealing Chains Modified.

The original Adamantine Sealing Chains were used by the Fourth Hokage's wife, Kushina Uzumaki.

She was a member of the Uzumaki Clan and the Nine-Tails jinchuriki; her bloodline was undoubtedly pushed to its peak, so there was no need to mention her chakra reserves.

The fact that she could use the Adamantine Sealing Chains to restrain the Nine-Tails even while severely injured showed just how powerful this sealing technique was.

The Adamantine Sealing Chains Modified that Su Yu received was derived from the Adamantine Sealing Chains.

The principle of this sealing technique was to generate a chakra chain to bind the opponent.

And Su Yu, by utilizing the Adamantine Sealing Chains Modified, reverse-engineered the original Adamantine Sealing Chains.

This was actually not difficult, mainly because he possessed the bloodline of the Uzumaki Clan, and the Adamantine Sealing Chains were originally a unique sealing technique of the Uzumaki Clan.

The authentic Adamantine Sealing Chains would allow Su Yu to seal a Tailed Beast directly into his own body.

His first reaction was that there was a wild Three-Tails waiting for him to capture it.

Then, he dismissed the idea.

Not to mention the immense risk involved, the Akatsuki's primary goal was the Tailed Beasts; if he were to seal a Tailed Beast into his own body, it would be equivalent to courting death.

However, using the Adamantine Sealing Chains to seal a portion of a Tailed Beast's chakra was feasible.

In other words, he could possess a portion of the Three-Tails' chakra.

Regarding medical ninjutsu.

The Healing Technique and Chakra Scalpel were not difficult.

The main requirement was the control of chakra, which had to be extremely precise.

Su Yu had long since mastered his chakra control through Water Surface Walking and Tree Climbing.

After the training for the Rasengan as well.

His medical ninjutsu, much like his taijutsu, was quite good.

The only thing he did not practice was the Konoha-Style Kenjutsu.

After all, this was an era dominated by ninjutsu; trying to defeat ninjutsu with swordsmanship was somewhat unrealistic.

Moreover, the Byakugan and Sharingan were already enough to keep him in an invincible position.

Now, the task he needed to do was simple: upgrade his Sharingan as quickly as possible.

Ten achievements had been completed, and the ten opportunities to draw abilities could not be missed.

When Su Yu returned to Konoha.

It was just in time for lunch.

During his days in the forest, he had brought plenty of food that required preparation, and his cooking skills were barely passable.

As soon as he stepped out of the forest.

He arrived at Ichiraku Ramen.

Just as he stepped into the shop.

Su Yu saw Kakashi and the others.

Kakashi glanced at Su Yu, noticing the Chunin vest on his body, and was slightly taken aback.

"Greetings, Jonin Kakashi." Su Yu bowed respectfully.

"If I recall correctly, you are a newly graduated Genin, just like them, aren't you?" Kakashi asked, puzzled.

"Su Yu, have you already become a Chunin?" Haruno Sakura asked in surprise.

"Su Yu, you're so amazing!" Naruto Uzumaki said, his face full of admiration.

Only Uchiha Sasuke let out a cold snort, looking somewhat disdainful.

"I passed the Anbu Chunin examination," Su Yu replied simply.

Kakashi was shocked.

Having come from the Anbu himself, he naturally knew the difficulty of the Anbu examinations; even for the Chunin level, one could not even participate without the necessary strength.

To be able to participate in this examination and pass it meant his strength was at least at the peak of the Chunin level.

Thinking of this, he looked at Naruto Uzumaki, Uchiha Sasuke, and Haruno Sakura.

"The three of you, do you want to see just how strong an Anbu Chunin is?"

"Can we?" Naruto Uzumaki's eyes lit up.

"The three of us against just Su Yu?" Haruno Sakura felt like it might be bullying.

Uchiha Sasuke, however, was full of fighting spirit.

"Su Yu, I'll treat you to a meal, and in return, why don't you help me test their strength?" Kakashi said to Su Yu.

"No problem." Su Yu did not refuse.

The current main cast was still quite weak.

He had just learned some ninjutsu, and they would be perfect for testing them out.

After a hearty meal.

The group arrived at the training ground.

Naruto Uzumaki spent the entire way asking Su Yu if the Anbu Chunin examination was difficult, how one could quickly become a Chunin, and what methods Su Yu used to get stronger.

Regarding the Anbu Chunin examination, Su Yu only said it wasn't difficult. As for how to become a Chunin quickly, the method was naturally simple: work hard to get stronger.

And the method to get stronger was to train in taijutsu, training constantly and continuously increasing the difficulty.

In reality, this training method was only truly suitable for those with the bloodline of the Uzumaki Clan.

This type of training could maximize the activation of one's own bloodline and increase chakra levels.

On the training ground.

Su Yu looked at the main cast opposite him.

"You don't need to worry about the situation of one against three, because I have companions as well."

After he finished speaking, he formed a seal.

Two Shadow Clones appeared by his side.

"Naruto, Sakura, you two go ahead and spar with my Shadow Clones. I'll see just how impressive the Uchiha Clan really is." As soon as Su Yu finished speaking, the two Shadow Clones charged forward.

Naruto Uzumaki and Haruno Sakura exchanged a glance and moved to the side, leaving space for Su Yu and Uchiha Sasuke to fight.

Su Yu looked at Uchiha Sasuke without saying a word.

Uchiha Sasuke let out a cold snort and lunged at Su Yu.

His taijutsu was indeed decent, at least at the mastery level.

Unfortunately, Su Yu's taijutsu was at the proficiency level.

Su Yu dodged Uchiha Sasuke's attacks with ease.

This made Uchiha Sasuke realize the gap between them, and his attacks became even more ferocious.

Su Yu responded calmly and unhurriedly.

Uchiha Sasuke activated his Sharingan.

With the aid of the Sharingan, he finally managed to see Su Yu's movements clearly.

Unfortunately, seeing clearly and being able to land a hit were two different things.

"The Sharingan is indeed powerful. However, your striking speed cannot keep up with your Sharingan; simply put, your taijutsu is too poor," Su Yu remarked.

"What did you say?" Uchiha Sasuke flared with anger.

Su Yu did not answer, landing a light palm strike on Uchiha Sasuke's body.

Uchiha Sasuke's body stiffened as he felt the chakra within him go haywire, the sensation of pain feeling like needles pricking his skin.

"Being able to see it but unable to dodge it—it's useless," Su Yu commented flatly.
