Tsunade stared at that Anbu for a long time.
"Who are you?" she asked, "Why are you reporting this now?"
"My subordinate is a member of Root Organization, codenamed Fox." Anbu said, "After Master Danzo died, I have been waiting for the right time. Now that the village is facing a crisis, I think it is time to hand over this inheritance."
"The right time?" Tsunade sneered, "Are you testing me?"
"I dare not." Fox lowered his head, "It's just that Master Danzo made an explanation before his death. This inheritance can only be given to those who are truly capable of protecting Leaf."
"So now you think I have this ability?"
"Yes."
Tsunade stood up and walked to the fox.
"Take off the mask."
Fox hesitated for a moment, then took off his mask.
It was a very young face, looking like he was only in his early twenties. But his eyes were very weathered, as if he had experienced too much darkness.
"What's your name?" Tsunade asked.
"A." said the young man, " is the code name given to me by Lord Danzo."
"A?" Tsunade frowned, "Root Organization's code names are all arranged according to the heavenly stems and earthly branches. A is the first, which means you are the person Danzo trusts the most?"
"It used to be." A said, "But after Master Danzo died, I was just an ordinary Anbu."
Tsuna Teuchi measured him.
This young man's Chakra Wave moves very smoothly without any abnormalities. His mental state is also normal and does not look like he is being controlled.
But she still couldn't quite believe it.
"Kakashi." She called out.
Kakashi walked in from outside the door. He had been waiting outside the door in case of any accidents.
"Let Ino come." Tsunade said, "Check his mental state."
"Understood."
Ten minutes later, Ino arrived.
She carefully checked A's spiritual world with Mind Perception Technique, and finally shook her head.
"There is no problem," she said. "His mental world is normal and there are no traces of being possessed or controlled."
Tsunade was relieved.
"Then take me to see that inheritance." She said to A.
"Now?"
"Now."
A nodded, turned and left Hokage's Office.
Tsunade followed, and Kakashi and Ino also followed.
The four of them walked through the streets of Konoha and came to a group of abandoned buildings on the edge of the village.
This used to be Training Ground of Root Organization, and it was abandoned after Danzo died.
A led them into one of the buildings and down to the basement.
The basement is very empty, with only a few pillars supporting the ceiling.
Person A goes to the innermost wall and knocks on the wall in a specific order.
Click.
A crack opened in the wall, revealing a passage extending downward.
"Follow me." A said.
The four of them walked down the passage.
The passage is very long and gets colder as you go down.
After walking for about ten minutes, we finally reached the end.
It was a huge Underground Space, as big as three football fields.
The space is filled with various experimental equipment, Culture Tank, and densely packed scroll racks.
"This is Master Danzo's secret base." A said, "All his research results during his lifetime are here."
Tsunade walked in and picked up a scroll.
What is recorded above is the transplantation experiment record of First Generation Cells.
The dense data is terrifyingly detailed.
"These experiments..." She turned a few pages, her expression getting increasingly ugly, "Were they all done with living people?"
"Yes." A said calmly, "Master Danzo believes that in order to make Leaf stronger, it is necessary to sacrifice some people."
"Asshole!" Tsunade slammed the scroll to the ground, "What does he think of this person?"
"Tools." A said, "In the eyes of Lord Danzo, except Leaf, everything else is a tool."
Tsunade took a deep breath and tried to suppress the anger in his heart.
She knew now was not the time to get angry.
"Where is the information about Otsutsuki?" she asked.
"In the innermost part." A led them to the depths of the space.
There is a separate room there with Sealing Runes on the door.
A Hand Seals, unlock the seal.
There is only one table in the room, and there are three scrolls on the table.
Tsunade Pick up the first scroll and open it.
What is recorded above is the history of the Ōtsutsuki Clan.
From when they came to the earth, to planting God Tree, to Kaguya eating the fruits.
All details are clearly written.
"How did Danzo know this?" Kakashi asked.
"During the Land of Rain war, he captured a White Zetsu." A said, "This information was extracted from the memory of that White Zetsu."
"White Zetsu's memory?" Ino was stunned, "But White Zetsu shouldn't have memory."
"Most White Zetsu do have no memory." A said, "But the one captured by Master Danzo is different. It is the first batch of White Zetsu that was created, and it retains some memory fragments about Kaguya."
Tsunade Continue to read below.
The second scroll records the sealing method of Kaguya.
Sage of Six Paths and his brother used Chibaku Tensei to seal the body of Kaguya in the core of the moon.
But the seal is not perfect and will loosen every once in a while.
Someone needs to reinforce it regularly.
"Is this why Moon Country exists?" Tsunade asked.
"Yes." A nodded, "The ancestors of Moon Country are the descendants of Sage of Six Paths, and they have guarded the seal for generations."
"What about Kageyama?"
"Kageyama is the descendant of Otsutsuki Hamura." A said, "Hamura is the younger brother of Sage of Six Paths. He stayed on the moon to monitor the seal of Kaguya."
Tsunade Pick up the third scroll.
What is recorded on this scroll is the information of Black Zetsu.
Black Zetsu is the will of Kaguya, and its purpose is to resurrect Kaguya.
It can possess anyone and is almost undetectable.
The only weakness is that it cannot possess the person who owns Six Paths Power.
"Six Paths Power?" Tsunade's eyes lit up.
"Yes." A said, "Six Paths Power is the nemesis of Kaguya. Only those who possess Six Paths Power can truly fight against her."
"Then Naruto and Sasuke--"
"The two of them are the most promising people to awaken the complete Six Paths Power." A said, "One is the reincarnation of Asura, and the other is the reincarnation of Indra. If they can join forces, they may be able to defeat Kaguya."
Tsunade Close the scroll.
She now finally understood the whole situation.
Kaguya was sealed on the moon, but the seal is loosening.
Black Zetsu is lurking in the dark, ready to resurrect Kaguya at any time.
And their only hope is Naruto and Sasuke.
"I want to take these scrolls with me," she said.
"Okay." A nodded, "But there is one thing I must remind you."
"What?"
" Lord Danzo left a prophecy before he died."
"Prophecy?"
"He said that Leaf will face an unprecedented crisis." A said, "That crisis does not come from external enemies, but from within."
"Inside?" Tsunade frowned.
"Yes." A said, "Master Danzo suspects that Black Zetsu has possessed the senior officials of Leaf."
