The Jiang Clan had integrated the Dark Blue Cold Iron into the iron door. It was thus reasonable that an ancient martial art practitioner in the Qi Nucleation realm would not be able to open it. After all, the Dark Blue Cold Iron was a material made in the world of Immortal Cultivators. Although it was something very average in the world of Immortal Cultivators, it was still very valuable on the whole.
A bright look flashed in Mo Wen's eyes, and then he punched the iron door fiercely. In the next moment, there was a huge roar, and that iron door instantly shattered. It collapsed dramatically and caused the dust all around it to fly up.
Zhou Honglu was shocked. That iron door had not been affected a single bit by ancient martial art practitioners in the Qi Nucleation realm, yet it had been destroyed by Mo Wen with a casual punch. This youth's capabilities were indeed frightening.
