The most incredible thing is that the girls who should have liked the protagonist all fell in love with the supporting role of Mu Zhian. Looking at the beautiful girls around her, Mu Zhian had a bold idea and was determined to kill it. The protagonist, turn over to be the master.
After finally pacing several protagonists, he got a lot of resources. In order to improve the strength of the girls, he shared many resources with the girls around him.
I thought that I, who enjoyed many resources, would be able to become an emperor in the future, and ascend to immortality.
Until one day, watching the sky robbery clouds rolling, and several empresses who were reborn in the thunder calamity, Mu Zhian's eyes gradually lost the light, and he muttered:
"I'm so stupid, really... I thought that after killing those chosen sons, I would be the protagonist of the new world, and I would be the future powerhouse of Ascension Stage, but I didn't expect... They turned out to be the protagonists."
