戰神
After Guo Kan returned to China with Hulagu Khan following Möngke Khan's death, Guo Kan helped Kublai Khan in the difficult conquest of Southern Song Dynasty of Southern China. Khubilai's accession as becoming Khan allowed him to select the best Yuan Generals to serve him. Subutai and Jebe both died of old age, and Guo Kan was the last of the 'Gods of War', so the new Great Khan Khubilai assigned Guo Kan to command the final Yuan expedition and reunification of China.
