Everyone thinks Qin Muwan and Ye Xun are doomed to die. If they’re killed, the Armor Alliance’s dirty deeds will never come to light! But... Ye Xun steps forward from behind Qin Muwan. The ordinary man in their eyes transforms into the Imperial Armor! The entire Armor Alliance is shaken to the core! The Imperial Armor they’ve dreamed of obtaining has appeared, and in such a way! But to Ye Xun, none of it matters anymore! The Armor Alliance, the people at the top, all of them! If they dare target his sister, they can all die! “Peak Imperial Armor? What the heck is ‘Heaven and Earth in My Palm’?!”
