Anbu is the short of Ansatsu Senjutsu Tokushu Butai which mean Special Assassination and Tactical Squad, was established by Nidaime Hokage. At the beginning, their most important function was to protect the Hokage and defend against foreign enemies. When they execute mission, they will hide their identity with a white animal mask.
The work of Anbu is boring and full of blood and the mission is also not easy at all.
Of course, they still need to get the trust of Hokage.
Speaking of this, there are now two types of Anbu, one is Anbu which belongs only to Hokage, and the other belongs to the Root that Danzo lead.
Of course they never get on each other ways but they also never help each other.
After all, the conflict between Danzo and the Sandaime is not a secret for the Village's top people.
Anbu Great Hall is the base of Anbu that belong only to Hokage.
Kakashi is no stranger of this place, although he has not been here since he was reborn, but the previous Kakashi was a frequent visitor here.
The Anbu who had previously teamed up with Kakashi had died in the Kyuubi's attack, so Sandaime arranged new teammates for Kakashi this time.
And Kakashi also know his new teammates, after all, those three people were always next to the Minato, Kakashi who was Minato's diciple, naturally has met them before.
When Kakashi came to Anbu Great Hall, it was still look the same as he remembered, and then he start to look for his new teammates.
At this time, there are not a lot of people so Kakashi recognized their location after looking for a while.
When Kakashi arrived, the three also saw Kakashi.
"Hey Kakashi, you're late. We have waited for a long time now." Genma Shiranui said as they walk to Kakashi's location.
"Sorry, I just got the news." Kakashi hearing this was embarrassed, after all the original Kakashi is also always late and use strange reason, now that he late again. He needs to apologize.
"Well, since that is the case, let's go ahead and execute the mission."
"Okay, but what is the mission?" Kakashi asked curiously.
"Nothing much, it is just some daily missions. We need to go to the border of the Land of Fire and the Land of Lighting to see the situation, and get the latest information of the border defense from the security personnel there."
Among the three, Genma Shiranui is the oldest, at the same time he is also a very calm person, so he is the one who convey the Mission.
"Oh okay then. Are we going now?" Kakashi asked.
"Don't be so anxious, there is an hour to prepare. After an hour, we then gather at the gate of the village, do you get it?"
Genma Shiranui and the other two then leave.
Kakashi also go back to his home to prepare the necessary things. He then put all of his things inside the seal.
He then takes out a bag from inside his room, that bag looks like it never had been opened for a long time. He then takes out something from inside the bag, then Kakashi is feeling melacholy after seeing this.
Kakashi whispered while stroking the kunai that Minato has gifted to him.
Flying Thunder God Technique is a very strong Ninjutsu. Every person who masters Flying Thunder God Technique will be known as the fastest shinobi, and they will become a sign of the enemy's death.
Flying Thunder God Technique can be used to reach its seal location. And the seal will never disappear.
This terrifying Space Ninjutsu, to a certain extent, is more terrifying than Kamui.
This technique contains a very profound Space theory, even if Kakashi has extraordinary Ninjutsu talent, he is still confused by it.
Minato is not a petty person. He even teaches his platoon guard the Flying Thunder God Technique, of course he will also teach Kakashi about it.
It was only that at that time, Kakashi was struggling with the darkness in his heart, so Minato wait for him to be better before he teach him. It was just not expected that Minato would die and he's not able to teach him that Jutsu.
It's really a shame that no one has mastered that Jutsu again. Even Genma, Raido and Iwasi can only work together to use it, and it is also not the real Flying Thunder God Technique.
Perhaps only Nidaime Hokage and Minato are the ones who manage to master this Ninjutsu.
Kakashi thought of this, could not help but feel a little emotional, as he gently touches the kunai.
Suddenly, Kakashi found that something is a wrong. This kunai was supposed to be cold. How could it feel warm?
Kakashi looked at it and found out that it wasn't from the kunai, but it was from the seal!
The seal is actually feels warm! And there is also a faint Chakra's flow from there!
This is…Chakra of Minato?
Kakashi was surprised, after all Minato had passed away. It was amazing that his Chakra could still flow inside here.
Then he suddenly realise, if there is no trace of Chakra from Minato, how can he know and teleport to the specific location?
"It's really a terrifying Ninjutsu. Even if the Minato-sensei has passed away, the seal still plays a can be used. It is no wonder that in the original work, Minato-sensei who is being resurrected by Edo Tensei can still use the seal he left behind."
Seeing the seal is a bit warm, Kakashi has a desire to find out what kind of secret does this terrifying Space Ninjutsu have?
And since he wants to understand it, it is natural to take a good look with his eyes.
Kakashi opened his headband to reveal the Sharingan that had been sealed for a long time.
Three black Tomoe in the scarlet pupils kept turning, and Sharingan's observation is being use to the extreme by Kakashi. The purpose is to take a look at the secret of this Flying Thunder God Technique.
"This feeling… it is not enough. Ordinary Sharingan won't be able to look at this Jutsu's secret, it looks like I have to use it…"
"Mangekyo Sharingan! "
The three black Tomoe instantly merge into one to form a black dart shape.
Kakashi instantly felt that the insight of his left eye is greatly improved, but his Chakra is consumed at a terrifying pace.
"What a terrifying Ninjutsu, there are so many complicated secret hidden in this seal!"
Under Mangekyo's insight, Kakashi finally saw the tip of the iceberg of Flying Thunder God Technique, but this tip of the iceberg made Kakashi couldn't help but feel awed. No wonder that after Minato, no one was able master this Space Ninjutsu. This technique is really complicated and hard to understand.
Only a true genius like Minato can master this technique easily.
Just as Kakashi thinking about this, his left eye suddenly start to change and the black darts pattern began to turn!
He feels some kind of formidable suction at his left eye, and the seal from the kunai was directly sucked by Kakashi's left eye!
Kakashi, who has witnessed all this, can't understand what is going on right now.
