The Sea Song

At the sea near Yashan, a hundred thousand soldiers and civilians made their final leap, and history closed the final chapter of the Southern Song. But no one knew that a fleet, carried by the monsoon, was sailing with the last young emperor, the imperial seal, the royal library, and the last sparks of craftsmanship toward the unfathomable South Seas. They swore a blood oath: to bide their time and await the right moment. Seventy years later, the Yuan court is corrupt, and chaos spreads across the Central Plains. A fleet bearing the tattered flag of 'Song' returns from the horizon, carrying improved firearms, advanced navigation, and a group of young people who have never set foot on their homeland but believe wholeheartedly in 'rebuilding China.' They must face not only the dying Mongol cavalry but also the rising warlords, and a question that looms over all: After Yashan, does China still exist? This counterattack, delayed by seventy years, is it to reclaim the throne for the Zhao family, or to restore the backbone of this land? — Description from novelcodex.org
