Ancient mountains and seas

The mountain sea continent is a continent surrounded by sea water. On this land, there are many countries, with thousands of large and small decimals! Although Ye Yi, Ming Tang and Chen Chen can't stir the wind and rain, they have contributed a unified posture! "I, Dayong, uphold the burden of heaven and follow the will of the emperor Dayu, the only orthodoxy in the world, unify the mountains and seas under the emperor! I should change the year to shunshi and Amnesty the world!" (comply with God's will and be the only one in the beginning)
