"Whoosh, whoosh, whoosh, whoosh, whoosh, whoosh..."
Countless arrows shot forward like a myriad of flashes of lightning.
The speed actually reached two hundred meters per second, and the most crucial part was that they flew faster and faster in the sky, eventually surpassing the speed of sound, emitting a series of sonic booms.
Even more terrifying was that the flight path of these arrows was almost a straight line, not an arc.
Because of these crystal-powered arrows!
After being shot, the crystals at the tail of the arrows began to react violently, generating tremendous thrust. Moreover, the tail fins and arrowheads of these arrows were all specially aerodynamically designed to ensure straight flight.
A speed of four kilometers for the crystal-powered arrows was only a matter of a few seconds.
Stopping abruptly...
In the sky, countless dazzling lights flashed suddenly.
Then, numerous crystal-powered arrows rained down fiercely on the enemy's Sky Legion like a downpour.
