The pillars of flames had incinerated the NPC soldiers, killing them so fast that they could not even feel anything.
Little Rain's Level was already high enough that his damage was not suppressed. With so many powerful equipments and the skill's own ten times power output, instantly killing the Level 70 NPC soldiers was only expected. It would only be weird if he was not able to.
After the skill was cast, only less than 2,000 soldiers remained. Jiang Fei took his time to slowly kill them all one by one. Only when Jiang Fei reported again after killing every single NPC soldier, Seven Star Warrior and Billy Boy relieved the players that were guarding the convoy and returned to the normal formation.
