The soul of a modern social animal traveled through the Ninja world and became Ling Dou, an orphan from the Konoha War, which coincided with the end of the Second Ninja World War.
Forced by hunger and cold, he strayed into the ruins of Kaguya and accidentally ate a light blue ice crystal berry that did not belong to the ninja world - the frozen fruit mutated into ice escape. It has no bloodline or inheritance, but it has the power of rules to freeze all things.
Chakra only half that of a normal person? It doesn't matter, less fruit energy is better than more;
Is Wu Xueji being discriminated against? He used ice blades to condense frost, glacier trip, and ice-sealing reincarnation, and became known as the "Konoha Frost Imp" in three battles.
From genin to ANBU, from the border battlefield to Payne's invasion, Ling Dou relies on actual combat review and deliberate training to break through the situation. Ice escape restrains water escape, freezes chakra, elements become flesh, and unlocks the absolute zero field.
Coveted by Danzo, feared by the Ninja world, and watched by the Akatsuki organization, he stuck to his true heart amidst conspiracy and war, transforming from a survivor into a guardian of Konoha.
The Fourth War comes, the Ten-Tails appears, and Kaguya revives. Ling Dou finally reveals the truth: the ice fruit comes from another dimension, has the same origin as Kaguya, and is an extraterrestrial power that spans the world.
So what if there is no blood successor? With the power of the ice fruit, he sealed the ninja world in ice, broke the iron law of blood succession, and worked side by side with Nazuo to become a frost walker guarding Konoha, creating the ultimate legend of bloodless ice escape!
