Konoha: We, the Uchiha, are ready to give up!

Liu Jing was completely stunned after transmigrating into the Uchiha clan!
Relying on the ancient wisdom of his past life, he changed his name to Uchiha Jin and barely managed to get by by adhering to the principle of "survival".
Until Konoha 50.
The Third Shinobi World War was raging, and he, a fifth-year student at the Shinobi Academy, gloriously became a ninja (cannon fodder)!
He was stunned.
Is Hiruzen Sarutobi, that old bastard, unwilling to even finish sixth grade?
Uchiha Jin: "..."
He has a terrible headache!
The Third Hokage is targeting them from the outside, while Danzo, the "King of the Pot," is sharpening his knives.
Within the family, there are many traitors.
There was Uchiha Shisui, whose death was utterly worthless, and Uchiha Itachi, who was magnanimous, devoted to Konoha, and did not hesitate to annihilate his entire clan!
And Obito Uchiha, who only wanted to destroy the world for Rin's sake.
Holy crap! I'm totally devastated!
[Ding! Congratulations, host, for realizing the true meaning of life!]
