Naruto: King of Slacking, I Refuse to Overwork

After transmigrating into the Hokage world, Uchiha Jing becomes an orphan of the Uchiha clan. Knowing the shinobi world's fate and the clan's impending destruction, he sees through Konoha's chaos and his clanmates' foolishness. Just as the Third Shinobi World War breaks out, he's forced to graduate early and binds to the Lie Flat and Slacking Off System. He can grow stronger automatically by lying flat, and even unlocks the top-tier martial art, the Six Naval Forms. With three tomoe and the strength of an elite jonin, he keeps a low profile and pretends to be a good-for-nothing, refusing to get involved in conflicts. All he wants is to stay alive in peace and wait for the right moment to walk away unscathed.
