He originally thought that he would only be able to use it after a hundred years, but he did not expect that in just half a month's time, Qin Feng had already fused the star-slaying iron into his weapon.
To be able to kill an Immortal, not only did he need the star-slaying iron, his weapon would also have to be at least at the level of an Immortal.
"Hiss!"
Even Qian Mu Prime was shocked by Qin Feng's methods. He also suspected that Qin Feng had the support of some elite behind him.
Even though the Immortals of the Dark Coalition were here, there were as many Immortals as the number of stars in the billions of realms. Qian Mu Prime did not know the background of this Xuan Feng.
And at this moment, after Qin Feng slashed at Wraith Devil Prime, a dark starglobe suddenly appeared beneath his feet. After this starglobe appeared, even the Floating City could not withstand it and was enveloped in darkness.
