The war between the Luobu Kingdom and the Black Holy Mountain Kingdom was quite dramatic.
Simply put, in every aspect, the Luobu Kingdom was inferior to the Black Holy Mountain Kingdom: its population was less than four-fifths that of the Black Holy Mountain Kingdom, its territory less than two-thirds, and unlike the Black Holy Mountain Kingdom, it did not possess expansive plains—most of its land was mountainous. The Luobu Kingdom's official fleet was even more pitiful compared to the Black Holy Mountain Kingdom's, with not only older and outdated ships but also a count less than one-third.
For anyone assessing the situation, it seemed impossible for the Black Holy Mountain Kingdom to be defeated.
However—
About half a month ago, after prolonged negotiations failed over a disputed border territory, war erupted between the Black Holy Mountain Kingdom and the Luobu Kingdom.
