You have no choice

Lan Fen and Lan Deming were walking on the street with deep thoughts about their uncertain future. But before long, loud sirens started blaring off back in the castle.

The sudden noise jarred Lan Fen and Lan Deming from their thoughts, their heads snapping towards the direction of the castle. 

The loud, piercing sound echoed through the streets, causing a stir among the citizens. People started to murmur and speculate, fear and curiosity mixing in their eyes.

Lan Fen's heart raced. Sirens in the castle typically signified a major incident or a high-level alert. 

She exchanged a quick, concerned glance with Lan Deming. The siblings immediately knew that this was no ordinary event; something significant must have happened.

Without a word, they both quickened their pace back towards the castle, their minds racing with possibilities. Could it be an attack? Could some powerful creature that even Crawford couldn't handle have invaded the territory?
