Naruto: Rebirth of Yahiko, Starting with Generating Electricity from Rainwater

Reborn in the Third Ninja War, Yahiko awakens to modern memory, abandons the fantasy of "mutual understanding" in the original work, and relies on the Rain Country, where rainfall occurs all year round, to implement hydroelectric power generation and industrial farming, determined to end suffering through productivity. The plan for stable development was completely shattered by Obito's sudden visit with Lin alive, and his world view was thrown into doubt. After seeing through the collapse of the ninja world, Yahiko found a new way to establish the Ninja Management Association, recruiting weirdos from all walks of life: Scientific research bosses Orochimaru and Kabuto sit in the laboratory to improve grain and eradicate famine; Deidara, the explosives genius, becomes the backbone of infrastructure, blowing up mountains and rivers and building national railways; Black and White Zetsu joins the team to do odd jobs and engage in intelligence, and Uchiha Madara signs a contract to lead a team to prepare for interstellar development. Heroes from all walks of life gathered under his command, and enemies were everywhere. Countless forces in the ninja world were sharpening their swords to get rid of him. Yahiko looked at the skyrocketing pain points and sighed helplessly: Please, I really don't want the pain points to increase anymore! But this is just a prologue. As time goes by, when Yahiko awakens again in the form of Pain, the ninja world has entered the cyber era. The surge in productivity did not bring the expected peace, but instead gave birth to more terrifying monsters: class divisions, capital monopoly, and rampant giants. The former compatriots were divided into two worlds. Coupled with the secret infiltration of Tsukuyomi Sect, illusion and reality are intertwined, and happiness and pain are entangled. New dilemmas are coming one after another, new rules, new order, new bloodshed, and new pain. This time, Payne has to face a new troubled world and find a real way out.
