Naruto: Asking About Immortality with Mortal Wisdom

When the fire of science falls into the ocean of ninjutsu, will it be extinguished or start a prairie fire? The smoke of the Third Ninja World War had just dissipated, and a soul that did not belong to this world woke up in Konoha Hospital. Yaoshi Yan, a doctor of materials science in his previous life, is an orphan from the medical department in this life. There is no huge chakra of the Uzumaki clan, no Sharingan of the Uchiha clan, and no standard system plug-in for time travellers. His only weapon is the scientific thinking, research methods and cognitive system that transcend the times imprinted in his soul. This is a world where bloodline and destiny come first. But Yan wants to use data to confront experience, use logic to deconstruct mystery, and use replicable technology to challenge unspeakable secrets. As a result, the style of painting in the ninja world began to change: ·In the medical department, infection rates and recovery cycles are quantified into tables, and traditional "feelings" give way to precise "data." ·Next to the detonating charm workshop, a "bleeding patch" production line based on a standardized assembly line quietly appeared. ·In the forbidden laboratory of Orochimaru, one of the three ninjas, there is an assessment report on the "ethical boundaries of the chakra resonance field". Facing the crushing force of the Blood Succession Snare, Yan pushed up his non-existent glasses and calmly wrote in the experiment record: "Goal: Use mortal wisdom to build the first replicable rational road to immortality in this crazy world. Current progress: 0.01%." Ninja war? Messianic prophecy? Sorry, please don't interrupt my scientific research with metaphysics until I have completed controlled experiments and passed peer review.
