"Remember, this arrow is called the Cloud-Piercing Arrow. It has no lethality. Don't try to use it to attack the enemy. It only has one function: sending a message.

Before Zhou Shu finished speaking, Shi Songtao had already shot a Cloud-Piercing Arrow into the sky.
A whistle-like sound pierced the clouds.
Then the Cloud-Piercing Arrow exploded like a firework.
