In the eighth year of Emperor Hui of the Han Dynasty, Western Persia brazenly launched the first eastward crusade in order to open up the road to the east.

Pa You, the contemporary head of the Nanban Pa family, urgently asked for help from the Eastern Han Dynasty. But they got reinforcements, only a thousand, passing through the bay. Lost most of the news.

The Persian army was overwhelmed and fought all the way to the White City (later the City of Tides). The contemporary head of the Nanban Zapong family, Yululei mobilized the power of the whole clan to organize the Self-Defense Force (the prototype of the later Mountain Dog Army. The elephants of both sides engaged in their first encounter outside Tidal City. The Persian grain route was cut off, and in desperation, the marshal of the Eastern Expedition, Hanbani, wrote the quatrain "Looking West at the Tide", which has been passed down through the ages, and then committed suicide.

The leaves are dense and the moon is white arboreal crows, and the wind blows the leaves and hangs tears.

The tide is full of people, and he is alone in the east of his home.

Since then, the White City has officially changed its name to Tide City!

This is just a rough story, and when the main story line is really written, let's write these small stories. The background of the story is taken from the Soviet-German battle in World War II.
