The Scum Is Marvelous

"I was just joking." Cheng Sheng said and coughed when he saw their stupefied expressions. 

Everyone. "…" then it is not a very good joke! They thought with their faces covered in black lines. 

Cheng Sheng looked away and smiled, deciding to return to the topic. "This magic tool, aside from being a defensive weapon as a barrier as well as a killing tool to trap the enemy, and kill them inside – " he continued. " – this magic tool also could prevent the spiritual energy from leaking outside, and prevent the spiritual energy from outside enter inside." He explained. "In short, this could prevent the enemies from dragging others with them when they self-explode." He told them. 

Everyone's eyes widened in awe. They recalled the news of Qie Shi's subordinate how Lei Ling was internally injured after suppressing the enemy's self-explosion. If there would be more of these magic tools, then the mages don't need to be internally injured again!
