The crowd was also stunned. They thought that Ye Qingtang's dagger would definitely be broken. How could Chu Yi's sword break first?!
Only Master Du nodded his head slightly. He seemed to have predicted the outcome.
"Young man, you really forged this weapon?" Master Du looked towards Ye Qingtang and asked.
Ye Qingtang nodded. "I forged the dagger using black gold meteoric iron in combination with Spirit Crystals."
Master Du's eyesight changed as Ye Qingtang finished her words.
Spirit Crystals were completely useless for normal people. However, Master Du was trying to mix Spirit Crystals into the materials to forge weapons ever since half a year ago. There was no outcome until now.
When Du Sheng passed him the dagger previously, Master Du knew that the dagger was made of black gold meteoric iron. However, it was mixed with other things that he did not figure out.
Ye Qingtang's words answered Master Du's question.
