After Losing Command of the Army, I Turned the Tables with the Help of a Chisu Marrow Master

On the northern frontier of the Great Yong, the lone city of Shuofang is besieged by a hundred thousand Northern Rong cavalry. Its food and supplies are cut off, and its red marrow reserves are depleted.

Gu Linshuo, the last iron-blooded duke of the guardian Gu family, lost his parents in battle and had his military authority stripped away. Left with nothing but an empty title and old wounds that never heal, he still holds the city gates, a discarded pawn at court and a tool for the Left Chancellor to use in killing by proxy.

The whole city believes its fall is inevitable, until a frail youth from the labor camp charges onto the battlements carrying a red marrow flame-thrower.

Red marrow is a rare substance found only on the northern frontier of Great Yong. It burns hotter than lamp oil, can be solidified into a power source, and, when integrated into military weapons, becomes a formidable weapon against the enemy. It is the ultimate trump card in the defense of the northern frontier!

“Linshuo, I’m here to defend you.”

Xie Lanzhao, heir to the fallen Xie family, was protected by Gu Linshuo in the capital three years ago. Now, he braves wind and snow to travel a thousand miles into danger, carrying his painstakingly researched red marrow notes. Along the way, he keeps upgrading red marrow by leaps and bounds, from flame jets to rapid-fire power weapons, from blazing city walls to crystal-powered crossbow towers, from infantry shredders to mobile fortresses... He wields red marrow as a blade and ingenious inventions as his heart, building an unbreakable wall around the man he loves.

Gu Linshuo gathers his former troops, brings his armored battalion guards back, and topples the Left Chancellor’s trusted commandery governor. With iron-blooded cunning, he gradually reclaims control of the northern frontier’s military, finances, and government, clearing every obstacle from Xie Lanzhao’s path.

No suspicion, no betrayal, only two people protecting one another, each choosing the other.

He is Gu Linshuo’s iron-blooded duke, defending the realm in a river of blood;

He is Xie Lanzhao’s red marrow genius, securing the northern frontier with his inventions.

When a besieged city on the brink of ruin meets the wonders of red marrow, and an iron-blooded general joins forces with a technical genius, watch the two of them face every crisis side by side, melt the snow and set the frontier ablaze, defend this vast realm, and topple the rotten court!

Two powerhouses joining forces, exhilarating triumphs and heartbreaking torment, political intrigue + ingenious technology + mutual devotion, with thrills from start to finish!
