Southern Ship

In the nuclear winter after the nuclear war between the brother civilizations of Earth, the surviving human seeds survived tenaciously. A young man named Nanfang drove an invincible steam ship built by three generations and searched for the warm sea in the south on the boundless ice field. During the journey, there are friends to help, enemies to pursue, and higher civilizations to look down on. Whether the warm sea that our ancestors talked about exists or not, we have to wait for our protagonist to fearlessly explore it.
