Five minutes later...

　　One of the examiners coughed in embarra.s.sment. "Little friend, what's the use of this soul cannon? The structure is a little special!"

　　Huo Yuhao smiled and replied, "It's also a Cla.s.s 4 soul tool. It's considered a high-powered soul cannon. I used a special technique to create it."

　　After whispering to one another, the chief judge looked at the other two and said, "Both of you created Cla.s.s 4 offensive-type soul cannons. It's very difficult to determine which is better. I suggest that the two of you challenge each other to determine the winner. After all, it's important that a engineer be able to use a soul tool to fight!"

　　"Alright!" Gao Dalou agreed readily. While rare metals were very attractive to him, a soul engineer like Huo Yuhao was also very tempting! Under such a circ.u.mstance, he was very willing to test out the strength of Huo Yuhao's soul cannon.
