Shamefully, Zhang Tie had not studied the pieces of these fierce deities that he acquired from the Heavens of Light during those years in the "dream". When he acquired their pieces, he was busy returning to Taixia Country. When he returned to Taixia Country, he was busy dealing with demons. Like other rarities and materials that he collected in the Castle of Black Iron, these pieces of fierce deities were just put in the warehouse in idle. Previously, he wanted to study the functions of these pieces; however, Meng Shidao and the dominant demon deity didn't leave time to him...
Now, Zhang Tie had enough time.
That fierce deity's head was a typical head of an ox-headed demon. It felt as heavy as a huge rock in hand. The cut was as smooth and neat as glass. After taking a closer look at it, Zhang Tie could see, blood vessels, bones, muscles, structures and organs inside the cut. However, all of them turned as hard as fossils.
