Mr. Darkness' explanation left Sheyan a bit puzzled. According to common sense, if the robot disintegrated, they should have passed the mission. Why would it trigger a catastrophe instead? Wasn't it a good thing to defeat the enemy without fighting?
But Mr. Darkness' following words explained everything.
"The energy core of this robot is a nuclear core. Once the robot disintegrates, the nuclear energy will go out of control....and the mission item will also be destroyed. That's exactly the error in judgement our MT made the the last time we came here. He attempted to slowly drag the fight on in order to trigger the disintegration of the robot. When the nuclear explosion happened, he was right in the center of the explosion zone. He was really lucky to be able to use a life-saving item in time, so he managed to survive."
