It was a one-sided massacre. And the massacres were Lucifer and Belial, and the victims were more than 50 pirates.
The speed of Lucifer and Belial's attacks was too fast, and with Lucifer's use of Shadow Movement, the pirates would never have a chance against him.
Lucifer kept using Shadow Movement to jump into the shadows of the pirates, then suddenly appeared from behind them and finished them off. The pirates could only stand still and wait for death without being able to do anything.
Even if they wanted to hit Lucifer, they couldn't see where Lucifer was to attack him.
"What the hell is this guy?" The pirates could only scream in despair.
"Don't pay attention to this guy, focus on the guy with the armor!"
Since they couldn't hit Lucifer, they decided to switch their target to Belial, which the pirates didn't even know was an even more foolish choice.
