"What?" Sect Leader Su was stunned when he heard the last part, "Their own disciples!?"
"Yes, their own disciples were exploding," Grand Elder nodded with a grave expression, "Not all of them, but there would be someone who would explode any time."
"There was chaos all around. And before the elder could recover, one of the disciples beside him shouted 'those' words and exploded."
"The elder then lost consciousness and was somehow saved by the debris."
Grand Elder took another pause and said, "That is not the end. From the disciple's shout, everyone investigating the incident was sure that there was some relation between the assassins and these disciples who exploded."
"There wasn't a definite confirmed answer to this relation. However, someone proposed a theory which almost everyone agreed on."
"What did the theory say?" Sect Leader Su asked.
