Naruto: Legend of the Thousand Sources

Tobirama's tone was cold and decisive, and he ordered the plan to be launched: "The 'Thousand Sources' has been completed, and it needs to be protected by the 'Root' that is absolutely loyal, has outstanding abilities and is always hidden in darkness, and will be handed over to the successors when the time comes." Senju Arashi—with a face as strong as Hashirama, and eyes as sharp as Tobirama—came forward and knelt down on one knee. Mito told softly but solemnly: "'Qianyuan' contains Hashirama's life force, my sealing power, and the core is locked with the resentment and power of the nine tails. You will say goodbye to the sun forever and give up the Senju name. No one will know your achievements and sacrifices, and your descendants will also inherit the fate. Can you think clearly?" Arashi looked at Hashirama's tiredness and determination, Tobirama's coldness that was unquestionable, Mito's concern and tenderness, and finally looked at his wife and children at the edge of the secret realm - his wife was in tears but silently supporting him, and the baby seemed to be feeling solemn and babbling. He closed his eyes and suppressed his attachment, and when he opened them he was left with determination: "From today on, my descendants and I will be removed from the Thousand Hands family tree and remain anonymous forever. I am willing to be the 'root of the wood', nourish the crown of the leaves, and protect the 'Thousand Sources' to the death!" He took the core scroll handed to him by Tobirama and took up the mission. The "Thousand Sources" sacred tree in the secret realm is the source of chakra and the eternal fire in Konoha's darkest moments, and the Senju Arashi lineage is the eternal guardian of this fire.
