Previously, as Garland had rushed over quickly in order to kill Jiang Fei, he was struck by lightning not that far away from him. After Jiang Fei took a big step forward, Garland was already within the Dragon Bane's range!
"Go to hell!" Jiang Fei pulled the Dragon Bane's trigger. The Dragon's Bane's attacks were all sure-hit. So, without Jiang Fei having to aim properly, the attack had automatically flown toward Garland!
-369,184,000!
As the effect of Jiang Fei's Ruthless Barrage had disappeared a long time ago, he only had more than three million basic Attack Power. So, even with the Dragon's Bane that increased his Attack Power by a hundred times, he only dealt more than three-hundred million damage.
Even so, this amount of damage was enough to kill Garland who was already extremely low on Health Points!
