Shuichi Brand Power Bank

Upon hearing Shuichi's words, Kakashi immediately raised his hands and Hand Seals, unleashing "Explosion Release: Explosive Barrage!"

The Nature Transformation chakra quickly gathered in his throat, and the next moment he spat it out, sending it flying towards Shuichi, turning into a rain of pebbles that enveloped him.

"Earth Release: Earth Return!"

Shuichi flipped up a thick stone slab with his foot, and the raindrops of pebbles hit it, making a crackling and popping sound, just like the large firecrackers during the New Year in his previous life.

"This move has a large coverage area and consumes little chakra. It has a group attack effect against ordinary ninjas, so it's quite practical," he thought to himself.

"Explosion Release: Explosive Shuriken!"

Kakashi didn't stop moving. After releasing the first Ninjutsu, he immediately followed with the second. He held two Yellow Earth Shuriken in his hands, threw them, and they flew in a perfect arc around the earthen wall.

This attack was incredibly agile, and the combination of Shurikenjutsu allowed it to hit the enemy from a blind spot. Shuichi exclaimed in admiration as he jumped above, even leaving an Earth Clone for the enemy to explode. "You actually had similar ideas to mine! Not bad!"

The two Shuriken exploded instantly after piercing the Earth Clone, blasting it to smithereens. Shuichi glanced at it and immediately counterattacked, completing a hand Hand Seals while leaping, and simultaneously throwing three Kunai with his other hand, shouting, "Explosion Release: Explosive Kunai!"

"Earth Release · Earth Style: Earth Flow Wall!"

Seeing the Kunai speed, Kakashi was forced to continue channeling his chakra. A mud wall topped with three dog heads instantly rose up; the sharp-eyed Shuichi could even make out its detailed outline—it was a big-nosed pug. "Pakkun? Poor thing, he'll get smashed many more times in the future."

Whether by sheer coincidence or not, three Kunai pinpoint accuracy, creating a deafening boom at the same time. The shattered dog ears flew far away and disappeared from sight.

Kakashi was left looking disheveled. Shuichi's chakra control was so precise that he might have been injured if the power had been any greater. Clearly, Shuichi's mastery of Explosion Release far surpassed Kakashi's.

Afterwards, the two used Shadow Clone to hone their Explosion Release Ninjutsu, and also engaged in tactical maneuvers such as setting up landmines. Rumbling sounds echoed continuously from the depths of the forest, and a large number of trees were directly flattened, making them absolute masters of environmental destruction.

"Huff huff..."

Kakashi collapsed to the ground like a limp rag doll, his chest heaving as he gasped for breath. After Shuichi intensified the training, he could only activate his Sharingan. Although it wasn't as taxing as using the Lightning Cutter, he was still exhausted after a while.

"Hehe, you've become unable to move so quickly!" Shuichi walked over with a strange smile, an expression that made Kakashi feel a little uneasy.

"Your Explosion Release Ninjutsu is pretty well developed, but your physical fitness... well, it's still so-so. Now that you're one of my men, hurry up and take off your clothes!"

Kakashi: "???"

"Stop looking, hurry up and get to work. You don't want me to help you, do you?" Shuichi took out a Scroll from his body. "I just finished making something. Giving it to you will restore your virility and make your life less short and powerless."

"..."

Although he didn't know what the man was up to, he trusted him completely after knowing him for so many years, so Kakashi had no choice but to take off his shirt and sit up.

Shuichi unfurled the Scroll and wrote on it, then had Kakashi cut his finger to bleed, while simultaneously removing his Forehead Protector and inscribing dense arrays of spells on his body.

After finishing, Shuichi hand on Kakashi's Sharingan, "Sealing Connection Method!" All the techniques rapidly converged towards Kakashi's left eye and quickly disappeared completely.

"What kind of Fuinjutsu is this?" After being tormented on his body, Kakashi couldn't help but ask.

Shuichi pulled out a bag and tossed him two unremarkable strips of cloth. "These are Purple Aurora brand high-tech eye masks. They can not only prevent nearsightedness, but also make your body stronger."

"There are two eye masks in total. One is usually clipped inside your Forehead Protector, and the other is for sleeping at night. I guarantee you'll feel amazing. You can try it now."

Upon hearing this, Kakashi immediately sprang into action, tucking the strip of cloth behind his Forehead Protector and then wrapping it around his left eye before tying it to his head.

The moment he put it on, he felt a surge of heat flowing from the Forehead Protector into his left eye, almost negating the portion of chakra he supplied to his Sharingan.

"What is this thing? How can it have such a powerful effect?"

"Well, you'll find out later; it's one of the village's secrets," Shuichi replied calmly.

This is a large chunk of First Hokage Cells that he had Orochimaru cultivate. It was connected to Kakashi's left eye through Fuinjutsu, making it like an external power bank. Although the amount of chakra transferred was not large, its even and long-lasting characteristics were very suitable for Kakashi's situation.

"I'll tell you a few techniques. When you encounter a high-risk battle, you can unleash them to increase your output power and significantly extend your combat time." Shuichi showed him a few hand seals.

"However, this will temporarily reduce the effectiveness of the supplies, and excessive use might permanently disable them. Of course, you don't need to be overly frugal; I can make more when you run out. It's not that difficult."

With Shuichi's little Cheat/System, Kakashi's time to use Kamui will be greatly shortened, perhaps allowing him to activate it in his early twenties, more than ten years earlier than in the original story.

As July approached, Konoha was already buzzing with excitement after witnessing the Joint Chunin Exam.

Even though everyone couldn't see the first two exams, it didn't dampen their enthusiasm. They analyzed the strong players and even opened betting odds for the third round.

In that familiar laboratory, Anko pleaded with Orochimaru, "Sensei, I failed to become a Chunin last time Chunin of the Lord Hokage. This time, I'm determined to become famous like Shuichi- Senior Brother. Please go and see!"

Orochimaru shook the liquid in the test tube, turned his head, and revealed a wicked smile. "Alright, if you can make it to the third match, I'll be in the stands."

"That's great!"

Anko smiled like a flower. After being guided and trained by Shuichi, her foundation was more solid, and she was very confident. There was even an unspeakable ambition rising in her heart.

That means she'll push through the entire battlefield in this grand arena, just like Shuichi did back then. She's been secretly preparing for this moment, waiting to unleash her full power.

After receiving the answer she wanted, a while later, Anko finally left the lab to make preparations. The "Orochimaru" expression instantly collapsed, revealing that it was actually Shuichi in disguise after the Transformation Technique dispelled.

"Oh dear, the teacher's actions and expressions are really hard to imitate, I almost gave myself away!"

Shuichi felt that his chakra was running low. Sending a Shadow Clone this time was a bit of a miscalculation. Who would have thought that Anko would be so persistent?

"There's no way she'll be able to see it. There will be so many people on stage, she won't be able to notice anyway!" Shuichi muttered to himself.

Orochimaru has been at the Root Base recently, and he's in charge of patrolling outside the area, so he definitely won't see Anko's performance. He's mainly too lazy to watch rookies fight, and Sunagakure probably won't send anyone strong.

"No, maybe we can watch the last match." Shuichi grinned wickedly. "If nothing unexpected happens, she'll run into Shisui. I love seeing her get thrashed. I'll send a Shadow Clone to watch..."

"BOOM!"
