Republican-Era Young Marshal: From Spoiled Warlord to Commander in the War Against Japan

"Call me a spoiled brat? Then I'll use guns to build the Jiang family's backbone in this chaotic age!"

In an alternate Republic of China, the nation is beset by turmoil, with foreign powers pressing in from all sides. Jiang Chen, mocked as a "green young marshal," unexpectedly binds himself to a "Strong Army System." Starting with the mess of taking charge of a corner of the Southwest, he advances one careful step at a time.

He conceals his strength, first reorganizing the army, then developing the arms industry. Using technology analyzed by the System, he improves firearms and doubles the accuracy of old rifles. He takes advantage of the mountainous terrain to design light artillery, making up for the lack of heavy firepower. He even secretly trains a disciplined, flexible "mountain iron fist" force, proving wrong the warlords who mocked him for being "better at putting on a show than handling guns."

With the Japanese invaders' iron hooves closing in step by step, he understands the vast gap in national strength and never dreams of an easy victory. When the Marco Polo Bridge Incident breaks out, he leads his troops on a night march to reinforce the front. No armored divisions appear out of nowhere; instead, he builds defenses with blood and ingenuity. He lays ambushes in the Taihang Mountains, tearing open Japanese supply lines with surprise attacks; plants minefields in villages on the plains to slow their mechanized forces; and uses an improved communications system to coordinate allied troops, winning one small but crucial battle after another.

This isn't an effortless triumph, but a difficult rise amid chaos. He stands firm against internal criticism while pooling the Southwest's resources to build an arsenal; maneuvers among the various factions, seizing territory and building strength amid the warlord conflicts; and personally leads from the front against the Japanese. With every hard-fought battle, he casts off the label of "spoiled brat" and makes the name "Marshal Jiang of the Southwest" one of the most dreaded by the Japanese. He carves a path to survival out of utter despair and reforges the backbone of the nation!
