Konoha's Last Line of Defense!

Konoha's Scroll of Seals was famous, and Gong Yi had looked up information about it in his previous life.

But since crossing over, this was his first time coming into contact with it.

As he browsed through it, he discovered that it recorded far more Ninjutsu than the few that had been revealed.

Besides the well-known Flying Thunder God, Shadow Clone Technique, and Impure World Reincarnation, there were many other Ninjutsu that few people knew about.

But just as the Third Hokage had said, they were extremely difficult to learn and could even cause severe backlash to the user, so few people practiced them.

Naturally, over time, many of these Ninjutsu became forbidden techniques and faded from public knowledge.

For instance, the two techniques Gong Yi had just seen required the corresponding Kekkei Genkai to use. No wonder they had never been revealed to the world.

It was precisely because there were so many high-level Ninjutsu and forbidden techniques that they could be compiled into a book.

If it only contained a few techniques, it wouldn't be worthy of being called the Scroll of Seals.

If he had the chance, Gong Yi would definitely choose Impure World Reincarnation.

However, the Third Hokage would never agree to let him learn that technique. He might even grow suspicious of him.

As a second choice, Gong Yi could only set his sights on other Ninjutsu.

Flying Thunder God Technique: essential Ninjutsu for traveling, killing, and looting!

Unfortunately, it demanded far too much talent for Space-Time Ninjutsu. Learning it right away was simply impossible.

Even Minato Namikaze had only mastered it by combining Shurikenjutsu with the Uzumaki Clan's Sealing Technique and making use of his exceptional talent for Space-Time Ninjutsu.

Gong Yi had no knowledge of Sealing Technique, so he gave up on that option.

In the end, he set his sights on the Eight Gates.

The power of the Eight Gates was beyond question. If you knew, you knew.

And the technique hadn't been created by Might Duy, Might Guy's father, as the rumors claimed.

In fact, this Ninjutsu had already appeared during the Warring States period.

When Uchiha Madara was revived through Impure World Reincarnation and saw Might Guy open the final gate, he made a comment about it. That proved the technique had existed during the Warring States period.

So it was only natural that Konoha had managed to collect it.

Seeing that Gong Yi had made his choice, the Third Hokage prepared to undo the seal and let him copy down the relevant training instructions.

But when he heard the words "Eight Gates," he hesitated.

"Gong Yi, you've seen what happens when you learn this Ninjutsu. Are you sure you want to train in the Eight Gates?"

Gong Yi nodded. "I'm sure! My chakra reserves are too small for me to make much progress with Ninjutsu. The Eight Gates are perfect for me!"

"Your body won't be able to withstand it!"

"Lord Hokage, please trust me! At the Academy, I'm the most diligent about physical training. Even Might Guy can't keep up with me. I'm confident I can master this technique."

Gong Yi paused, then said earnestly, "If the village ever faces a powerful enemy that no one can resist, I'll open the final gate and unleash power beyond Kage Level to protect the village!"

The Third Hokage stared hard at Gong Yi, as if trying to see straight through him.

He knew how powerful the Eight Gates were. All eight gates opened, and the user would gain power beyond Kage Level. It had never been verified, but such a rumor wouldn't have spread unless there was some truth to it.

Even if it didn't surpass Kage Level, it would at least grant power on par with it.

If Gong Yi truly had the resolve to give his life to protect the village, then entrusting him with this Ninjutsu would be worth it.

"I hope you'll become the village's last line of defense!"

"As you wish, Lord Hokage!"

The Third Hokage no longer hesitated. He undid the seal on the technique and let Gong Yi begin memorizing the training instructions for the Eight Gates.

Gate of Opening, Gate of Rest, Gate of Life, Gate of Pain, Gate of Limit, Gate of View, Gate of Wonder, Gate of Death!

These were the Eight Gates!

They existed within everyone's body, restricting the flow of chakra.

The human body was extremely fragile, while chakra was a double-edged sword: it could harm others, but it could also harm its user.

Thus, the Eight Gates effectively restricted chakra from flowing beyond what the body could endure, preventing injury.

In a sense, this was the body's natural instinct.

This advanced Taijutsu taught ninja how to open the Eight Gates as safely as possible and draw out chakra far beyond their natural limits!

But it sounded as though anyone could practice the Eight Gates with this Taijutsu, and anyone who mastered the technique could become a Taijutsu expert.

In reality, it wasn't that simple.

Once someone gained far more chakra than they normally had, their body couldn't withstand it at all.

The moment that massive amount of chakra surged through the body, the chakra pathways, organs, and internal tissues might all be destroyed!

Therefore, to fight without strain after opening the Eight Gates and avoid dying on the spot when the technique ended, the body needed to be strong enough to withstand the burden.

Unconventional, grueling training that pushed the body beyond its limits for a long time.

Only then could one condition every part of the body and its organs to withstand the strain of opening the gates, minimizing the damage caused by the immense energy.

Gong Yi took a deep breath. He met every one of these requirements!

Four years of continuous basic training, completing the Undying Xiaoqiang mission, and enduring the terrifying pressure of eleven times gravity had made his physique monstrous!

Gong Yi believed that, apart from ninja who used secret techniques to stimulate their cells, few could keep up with him once he removed the elevenfold Gravity Technique.

The fact that he had defeated Kazama Heitetsu, an elite Jonin, in an instant with Taijutsu was proof enough!

"Since I already meet the requirements, I might as well try opening the first gate right away!"

"Gate of Opening! Open!"
