Within a minute, the barbarians' middle group sank into chaos as their men swiftly fell down dead one by one. They did not have the slightest clue of what hit them, and the unknown would always be the most fearsome. The barbarians could only watch with wide eyes as the brethren beside them lost their lives, one at a time.
Unfortunately, after killing more than a dozen barbarians, Tristan can no longer sense the blood pearl he made. It appeared to have diminished bit by bit from each hit. But it is still a very satisfying skill indeed.
"Dark magic!! Dark magic!!" shouted one of the barbarians, which unfortunately brought even more chaos to the already chaotic situation. Seeing their friends and companions died in succession made some of the barbarians charge forward in desperation. Alas, their attempt only resulted in them falling under the swings of Tristan's blade.
