The first thing Gu Mingshu, a doctor of thermodynamics, did when he transformed into Uesugi Hayano, the most inconspicuous handyman in the Konoha Armory, to accept reality was to take out his homemade grid ledger and record "Traveling through the Naruto world, survival rate 3%" in the first column of the entropy increase event - this probability is 0.2 Percentage points higher than his acceptance rate for the top journal that year, which is stable.
While others competed for blood to create blood inheritance, and made balls to practice Susanoo, he held a flat mirror with the word "Gu" engraved on the temple, and used a broken abacus he picked up to calculate ballistics. He relied on the "Arsenal of Truth System" to turn the ninja world into a military-industrial experimental field: he changed the direction of detonating symbols to bomb the chuunin who had deducted food stamps, used Naruto as a living chakra reactor to gather energy, and squatted on water and wood as first-charge gift packs for upgrades.
His code of conduct is written on the title page of the ledger: entropy increase is the ultimate truth of the universe, and explosion is the most efficient way of entropy increase. While the five major powers were still debating how to fight the Ninja World War, Gu Mingshu had already set up a chakra kinetic sniper rifle and calculated the critical entropy increase rate of the six spots in the scope.
