Back to the Southern Song to Become Emperor

Build a fleet and launch overseas trade, bringing in corn, spices, and rubber. Reform the tax system and increase revenue. Crack down harshly on corruption and clean up the bureaucracy. Establish an arsenal and develop firearms. Raise the status of military officials and appoint renowned ministers and generals. Annex Dali, Western Xia, the Western Regions, and Tibet. Defeat the Jin and reclaim lost lands. Drive out the Mongols and pacify the north.

The ruler's heart holds a vast realm, yet he is often troubled by love. War between the Song and Jin is unavoidable, but the Song emperor marries a Jin princess. A Song-Mongol war is inevitable sooner or later, yet the two nations have no choice but to intermarry.
