Yin-Yang Release Sealing Technique

"The memory I retain is that, for the sake of the mission, we had to erase each other's memories, which is why we lost our memories. As for why we erased our memories, Minato, I guess you should know, right?" Shiyu asked with a smile.

"I understand," Minato said.

"Our mission is complete! We can go back now. All the necessary memories are still in my mind," Shiyu said.

"Huh? Teacher Shiyu, why do I feel like you're a little different? The Yin Seal on your forehead seems to have changed?" Minato asked.

"Yes, that's right. Now it's not just the Yin Seal, there's also the Yang Seal, which is the Yin Yang Seal." Shiyu pretended not to remember.

At that time, the situation was extremely urgent. When Shiyu was about to burst, he directly used the Yang Release Seal Technique on himself, intending to take a gamble, but unexpectedly, it actually succeeded.

The power of the Dragon Vein surged into Shiyu's Yang Seal in an instant. Due to the interaction of Yin and Yang, Shiyu, like Jinchuriki, completely sealed the power of the Dragon Vein that was transmitted into his body.

Shiyu had actually absorbed almost all of the Dragon Vein's power. Minato and Queen Sara's sealing of it conveniently concealed this fact. In other words, the entire Dragon Vein had been drained by Shiyu.

What could be absorbed by Shiyu was absorbed by his main body; what could not be absorbed flowed into the Yin Yang Seal.

And the remaining Dragon Vein power is actually not much.

The power of the Dragon Vein is immense, yet Shiyu was able to completely empty it due to the Yin Yang Seal, which also demonstrates the power of the Yin Yang Seal from another perspective.

Minato Namikaze, Shiyu, and Kakashi quickly crossed the border of the Land of Wind and arrived in the Land of Land of Fire. They then quickly reached Konoha Ninja Village, and everyone felt a sense of familiarity when they saw the Konoha Gate again.

"So you're finally back? Let's go hand in our missions." The three went straight to the Hokage's office and reported all the missions they knew to the Third Hokage.

"I see. Since the mission is complete, that's enough." The Third Hokage nodded with satisfaction; an S-rank mission was now officially over.

Immediately afterwards, Shiyu returned to his residence and began to frantically study the Yang Release sealing technique. After all, the previous self-sealing technique was not very mature, and now he needed to study how to unseal it and how to seal and Hand Seals for others.

However, despite Shiyu's extraordinary talent, the Yang Release Seal Technique was extremely difficult to master. Out of necessity, Shiyu sought out Mito and Kushina, and the three of them began various exchanges and attempts. Time passed quickly, day after day, until one day, Shiyu burst into laughter.

"Completed! The Gouketu no Jutsu that completely releases the Yin Yang Seal! It's even more powerful than the Hundred Healings Technique! With all my chakra released, I will possess unimaginable fighting power!"

Immediately afterwards, Shiyu fully mastered the Seal Technique and Hand Seals of Yang Release.

Shiyu was about to release the seal on Xiao Xing, Lady Mito stopped Shiyu.

"Shiyu, the Yin Yang Seal is for sealing chakra. If someone uses this technique on Xiao Xing, they must have some purpose. Xiao Xing has learned enough Ninjutsu now. If the Yang Seal is removed, won't there be problems?" Mito sincerely advised.

Shiyu also realized what was happening.

"Yes, Xiao Xing is still young. If the Yang Release seal is lifted, what if something terrible happens and something happens to Xiao Xing?" Shiyu also felt that she had overlooked something.

"Wait a little longer. You're all still young. There's still time." Kushina also advised. Shiyu finally paused the process of releasing the seal on Xiao Xing. Shiyu returned to his residence and, by chance, saw his Meteor Blade.

"The Meteor Blade and the Dragon Fang Blade? Yes, I should go find Nao and Gray Fang-senpai. Having good swords but no good swordsmanship is utterly useless." Shiyu took down the Meteor Blade and the Dragon Fang Blade, put on his clothes, and headed towards the Hatake Clan.

Shiyu fought against Uchiha Shisui, he copied some of Shisui's sword techniques, but because they were not complete, they were not very practical in the battle.

"You are... Shiyu! You've finally arrived!" Kakashi Nao wasn't on a mission; he had just recovered from the injuries sustained Chunin Tournament and immediately began a sword duel with Hatake Sanyu at his own dojo.

"Nao, are you feeling better? I went on a mission and just got back," Shiyu said.

"I know, we were injured, and you and Minato Kakashi went on a mission." Nao didn't seem to care.

"Nao? Who is that?" A familiar voice came from inside the dojo.

"Father! It's my teammate Shiyu! He's finally here!"

"Oh? Why don't you invite him in?" Graytooth also looked quite interested.

In the World of Pirates of Hokage and One Piece, swords and knives are the same thing, and Grey Fang is currently holding a wooden katana, which he is slashing directly at Shiyu.

Shiyu immediately drew his Dragon Fang Blade, and Gray Fang's sword struck the Dragon Fang Blade, breaking it into pieces. However, Gray Fang still held the hilt of the sword.

"Is this the short sword you brought specifically to learn the Kakashi Sword Style?" Grey Fang said casually.

"Senior Gray Fang, no, it's just a divine artifact I obtained through a fortuitous encounter some time ago." Shiyu wasn't worried that Gray Fang wouldn't recognize its value.

As expected, Gray Fang nodded and said, "Indeed, this knife is definitely not from the mortal realm, but it still depends on who wields it, you brat."

"You promised to come and learn swordsmanship from me, why have you been dragging this out for so long? You deserve a beating." Gray Fang gradually softened his cold attitude and became more enthusiastic.

Nao also breathed a sigh of relief.

"Don't use your divine weapon yet, take this katana." Grey Fang tossed the wooden sword in his hand to Shiyu.

"Next, we'll continue with basic exercises. Nao, you'll do them too."

"This is a horizontal slash! This is a vertical slash! This is..." Grey Fang demonstrated all the parts he wanted to show, then asked, "These can't be copied even with the Sharingan. You can only slash and hack again and again until you find the feeling. How's that? No problems?"

Shiyu nodded and began slashing and hacking, as well as various other basic maneuvers, with Nao.

A long time passed, and beads of sweat dripped from their hair.

Greyfang nodded in satisfaction and said, "Good temperament. He's genuinely dedicated to the slashing. This guy is probably no ordinary genius. No wonder the Third Hokage also speaks highly of him."

"The basic training is almost complete. Next, we'll move on to the techniques." Grayfang then said, "First, the fixed techniques. When you can use the fixed techniques flexibly, it means you've truly entered the realm of swordsmanship and kendo."

Then, Greytooth began demonstrating his moves.

The two of them were studying diligently.
