================================
In the long and repetitive dream,
Quicksand constantly pours down.
The compass of destiny starts to tick.
The two wake up and embark on their separate journeys.
On this shore, you emerged from a perilous situation but were exiled to the harsh North Border, struggling to survive.
On the other shore, you found yourself in a maelstrom of power, striving to escape from a cage woven with conspiracies.
No need to bid farewell.
As time perpetually flows forward,
As the two shores will eventually meet,
You will meet each other one day.
