After all, it was just a probing attack. Even if this assault could not achieve the result Zachary wanted, it wouldn't affect him much. If worse came to worst, he would just switch to another method to continue probing.
Compared to the last time when the Flying Swords passed through the battleship's Energy Barrier without any obstacles, this time, as the Flying Swords were about to approach the battleship, the warship had already detected the high-speed Flying Swords heading towards them. The Close Defense Cannons on the deck rapidly fired a barrage of bullets that intertwined like chains in an attempt to block the swords' advance.
However, perhaps due to a misjudgment of the Flying Swords' flight speed, coupled with the fact that the swords hadn't yet entered the Energy Barrier and were still controlled by Zachary, even the barrage-like bullets from the Close Defense Cannons failed to hit any of the swords.
