Republican Era: The Strongest Young Marshal, Not an Inch of Fengtian Will Be Surrendered!

Shen Yanshan transmigrated to the Republican era and became a military commander. But when his father arranged a safe position for him behind the front lines, he wouldn't even give it a glance.

He grabbed his gun and headed for the front, going head-to-head with the Japanese. In the end, he was shot and nearly lost his life.

As a result, Shen Yanshan, a man from the modern era, transmigrated into this body and awakened the Cross-Time Military Arms System.

As long as he has enough resources, he can exchange them for any weapon within his knowledge!
