Realization

'That went surprisingly well. But dismissing Danzo felt too easy does he have a hidden card?'

Hiruzen couldn't be blamed for having such thought, because the Danzo of Naruto area left a deep impression in his memory. But soon he reacted.

Today Danzo didn't have the Root army of the future because Mito always oppose to it before. Because of that, at this time Root was just a special unit of ten people from Anbu charged to do most of the darker missions and special intelligence works.

Besides because Danzo wasn't that inhumane yet, those root members still had emotion so he couldn't take them away, and he wasn't an elder yet.

So even if Homura and Koharu tried to dissuade Hiruzen, he still end up firing Danzo smoothly. The only regret Hiruzen had was that he wasn't able to hear the famous sentence 'Hiruzen you will regret it!'

After finishing his 'talk' with Konoha F4 Hiruzen quickly joined Tsunade and the other and lead them to the building without answering any of their questions.

Once there, he lead them to the biggest sealing that could accommodate them all.

While they knew that Hiruzen wouldn't hurt them, but all those secrets and sealing marks on the ground made them wonder if they were in some shameful and shady secret place of Konoha. This time Orochimaru took the lead.

"Sarutobi-sensei, what is this place? And why every room in this building has that same sealing mark? What is this sealing technique?"

Feeling like it was a good moment to pretend, Hiruzen didn't answer immediately but talk about other things.

"Did you know that Tobirama-sensei conduct experiment and research on the mokuton after lord Hashirama's death?"

While most of the people present didn't know about it, but when they thought about Tobirama's character they weren't surprise. The only people who already knew were Hiruzen's disciples. But they were puzzled as to why their sensei brought up that subject until Orochimaru react.

Breathing a heavily, he started to probe.

"Yes, but sensei you told us that he failed. Could it be that he actually succeed?"

That question brought a chock through the crowd. Wood style! Konoha's Symbol! Tobirama succeed in bringing it back?

Wanting a clear response they all stare at Hiruzen with eager eyes, but were disappointed when the answer came.

"No, he was unsuccessful in his endeavor."

"Then don't talk about it and letting us hang there for nothing old man!" shout Tsunade with anger.

If we talk about who want to awaken the mokuton the most beside Nawaki, it was Tsunade. As the granddaughter of Hashirama and the one with the most potential the Senju clansmen had hoped that she could awaken Mokuton. Unfortunately she didn't respond to their wishes. But the most disappointed in this was actually Tsunade.

Understanding the mood of his student, Hiruzen stop playing with them.

"While Tobirama-sensei didn't succeed, he did find the key to awaken the Mokuton: Yang Chakra. But even though he found the key, as everyone know it has always been hard to harness the power of Yang and Yin Chakra especially when it comes to harness more of them to yourself.

After his death, I retake the project, but with now a different direction, Yôton. And today, I can tell you with certainty that I succeed. The seal techniques that you saw along the way and thus one are the fruit of my labor. The Domain of Vitality!

It's only function is to gather pure Yang Chakra for you to absorb. While there is no guarantee that you will awaken mokuton Tsunade. But with this, the chances to do so increase greatly."

That was big news! While they had some expectations when Orochimaru asked, but when Hiruzen himself somewhat confirm it they couldn't contain their excitations.

Without wasting anymore time, Hiruzen lead them inside the seal while instructing them on how it works.

Because of the number of strong people present, Hiruzen was confident that there will be enough Yang Chakra for everyone to absorb so he participate in it too. After all, everyones physic was different so obviously they could only absorb so much.

Because all they had to do was inject Chakra in the seal, the overall process didn't take too long only 40 minutes. The conversion of Yang Chakra was almost instant, so most of those 40 minutes were more for them to absorb the Yang Chakra than anything else.

As Hiruzen expected, after absorbing the Yang Chakra his body got younger due to increase in vitality. From a mid forty looking guy to early twenty. While it didn't happen instantly, the transformation was still quick. But that wasn't the end, as time pass he felt his body get stronger and stronger.

Before getting this boost, his body was already as strong as a normal taijutsu specialist elite jounin, but now he was sure that he could wrestle with the third Raikage or some weak tail beast, with strength alone. Not to mention that he knew that after refining his Chakra, the amount will surely double.

All in all Hiruzen got stronger again.

Being the strongest here, he was the last one to finish. Opening his eyes, he saw that nobody was looking at him, but were eagerly watching Tsunade, eyes close and joined hand concentrating on something.

Suddenly her blue Chakra unleashed outside and start to take two distinct color: deep blue and brown.

Hiruzen immediately knew that it was the the nature transformation of Earth and Water.

As a Naruto fan, Hiruzen always thought that it was a pity and ironical that Tsunade didn't possess the Mokuton, but her clan rival did. Even Yamato, a random guy did, but not her! So he did hope that she could awaken it today.

Under the gaze of her clansmen, teacher and friends, Tsunade finally started to merge her two different Chakra.

At first, the two different Chakra nature seemed to reject very much, acting very violently. But when people start to discourage, a green color Chakra full of vitality suddenly appear between them, calming both of them.

Without any warning , the green Chakra started to absorb both of them quickly. The process didn't take more than 5 second. After absorbing all those Chakra, the Green Chakra who return inside Tsunade seems to become darker.

Once all the Chakra come back, Tsunade finally opened her eyes, but without waiting for them to ask the result she suddenly shout.

"Mokuton : Wood barrier technique!"

Beams of wood emerge, creating a half dome in front of her.

Mokuton. It appear once again!

Seeing the miracle being perform in of them made especially the senju quite emotional. Even Tsunade had some tear up to her eyes.

'Grandpa, I did! I didn't dishonor your name.'

Turning her head, Tsunade face her teacher as the other around were celebrating.

"Oldma- Teacher, Than..."

But Hiruzen didn't let her finish. But with a smile told her.

"Congratulation Tsunade. Your grandfather will be very happy for you and especially proud." then without waiting for her to reply, he decisively went out.

Even though Hiruzen received the memories of both Hiruzen Sarutobi and had been influenced a little bit by them, he knew. Or more precisely he could feel that until now he still had a sense of surreality in what was happening.

A day ago he was still a twenty years old student asking himself what he will be doing after graduation, but now he became one of the most controversial character of Naruto.

The transition was so fast that he didn't have the time to adjust and adapt at all.

It wasn't until returning home and seeing Biwako looking worried and waiting for him that he felt something.

"Hiruzen, I heard what happen." said Biwako, hugging Hiruzen. "Everyone is talking about it. Do you really need to go? Many ninjas said that this was a more of suicide mission than a rescue."

'Biwako...'

Yes, Hiruzen forgot about his wife and kids. No it would be more exact to say that he didn't want to think about them. But seeing the worried look of Biwako and the clueless Look of Asuma, Hiruzen finally had a change of heart.

No matter if this was a world of super power or not, at the end of the day, they were people with family too.

When he was still on earth he lost both his parents a month ago. And even now he was still impact by their deaths. Which is why seeing Hiruzen's family in front of him, he felt sad.

"Biwako, I'm sorry." Hearing Hiruzen apologize, Biwako shook her head and smile sadly.

"I don't blame you, Hiruzen. I know that as Hokage this is your duty. But please don't follow the footsteps of your predecessor and never come back from the Frontline. We need you alive."

Even though Biwako mistake the reason for his apologies, Hiruzen still nodded at her.

"Don't worry I'll be back. And still, I'm sorry."

'I'm sorry for replacing your husband. I promise you that I'll make it up to you.'

***************

Three hours later, Hiruzen stood in front of the wide open Konoha's Gates With with an army of Ninja behind him ready and full of momentum.

Taking a deep breath, Hiruzen steadied himself before taking the first step.

"Set off!"
