Batu the Iron-Blooded: Transmigrating to the Yuan-Mongol Era to Unite the World

Lin Feng, a scholar of modern military history, transmigrated into the Mongol Empire of the 13th century after a car accident, becoming Batu, Khan of the Golden Horde. By then, the Mongol Empire had long since splintered. After the death of Güyük Khan, the four khanates of the Golden Horde, Chagatai, Ilkhanate, and Ögedei were locked in factional warfare. The Yuan Dynasty established by Kublai Khan dominated East Asia, Mongols turned their weapons against one another, and the once-mighty empire spanning Europe and Asia was falling apart.

At last, he marched east, trading artillery fire with the Yuan army along the Yellow River defenses before ending the Yuan Dynasty's internal strife in the imperial palace at Dadu. He reunited the fractured Mongol Empire and forged a unified, multiethnic empire that embraced Han, Mongol, Persian, and Islamic cultures, writing a tale of iron and
