With the advantage of range, Rocky's fleet was the first to open fire. Thanks to the new targeting system designed by Pelaya, the accuracy of the main guns was incredibly high, achieving nearly 50% hit rate even when engaging from 1500 meters away, resulting in over twenty warships of the City of Fury's fleet being sunk after the first volley.
The power of the Rune Main Cannons was so great that the typical warship's Defensive Net simply couldn't block it, and even though the City of Fury had already experienced the might of the Rune Main Cannons the day before, they had no means to counter this new weapon they had never seen before. The only thing Su De could do was to order the fleet to accelerate at full speed, planning to continue advancing while bearing the brunt of the enemy's cannonade.
