The protagonist was a college student who loved sharing practical knowledge about ancient survival skills, earning pocket money by serializing Transmigration Guide online.
Who would have thought his words would prove prophetic? He really did transmigrate into a chaotic era resembling the end of the Southern Song dynasty, becoming cannon fodder among the new recruits at a frontier stronghold and facing a battlefield as merciless as a meat grinder.
To survive, he turned the Transmigration Guide in his mind into reality. While training under a veteran, he put modern physics and military engineering knowledge to use, building an era-defying weapon, the “composite bow,” from whatever materials he could find, while mastering a military saber technique designed to kill with a single strike. Starting with improvements to the frontier army’s logistics, he steadily advanced the technology tree and crushed the foreign cavalry with overwhelming technological superiority.
When the foreign armies laid siege to the city and the court prepared to surrender territory in exchange for peace, the former frontier foot soldier had already raised an invincible army equipped with firearms and fine melee weapons far ahead of their time. Watch as he uses modern ingenuity to restore the backbone of the Han people!
The progress is fast enough, but I don't know which direction to talk about the rebellion.
