In Uchiha Yue's original plan, after destroying Kirigakure's war supplies depot, he had intended to train within the Land of Water. Once the depot had been destroyed, Kirigakure would lack the strength to fight Konoha again in the short term, conveniently leaving the entire war in a stalemate. Under such circumstances, Uchiha Yue would undoubtedly have time to build up his strength and advance from a quasi-Kage-level expert into a true Kage-level powerhouse.
However, when Uchiha Yue learned that Uchiha Fugaku intended to return to Konoha from the Land of Water front, he knew that his plan would likely fall apart.
