The Scum Is A Support 

Everyone's expression is solemn after they hear Cheng Sheng's explanation about his experiment and its result earlier when he fought against the enemies. Then, they all looked at Cheng Sheng's leave with xiao Ling who recorded their sects' refining process and brought along their swords for Cheng Sheng to refine. Just like what Cheng Sheng did with his own sword, which is xiao Ling's original body that he used earlier to cut the enemies, revealing that the enemies' wounds don't bleed since their wounds were severely burnt including their flesh and bones after Cheng Sheng's sword cut them! 

This is really horrifying. They have never seen this kind of injury before that could burn even the flesh and bones! 

"Hey, if our swords would be refined, we would be able to kill our enemies for good, right?" Kang Ce asked as he looked at Qian Tian, Qian Jue, and Shu Mu whose swords were taken by xiao Ling for Cheng Sheng to refine.
