Shan Sihan

In 1937, eight hundred Chinese soldiers fight under siege from a warehouse in the middle of the Shanghai battlefield, completely surrounded by the Japanese army.

Two sword spirits born from a shattered divine blade—brothers Zhaoyun and Muyun—are raised on opposing sides of a brutal war and reunite as enemies on the battlefield. When the truth of their bond is revealed, they join forces with a tribal princess to find the Emperor Sword, defeat a ruthless warlord, and restore peace to a world torn by conflict.
