So They’re the Main Characters

Mu Zhian transmigrates into a world of immortals and martial heroes, becoming a supporting character destined to serve as a stepping stone for the protagonist. He intends to get along with the protagonists, those chosen by heaven, but when he looks around, he realizes that the girls surrounding him are either the protagonist's childhood sweetheart or his fiancee. Most baffling of all, the girls who should have fallen for the protagonist have all fallen for Mu Zhian instead. Looking at the beautiful girls around him, Mu Zhian comes up with a daring idea: kill the protagonist and take his place as the main character.

After finally defeating several protagonists and gaining a wealth of resources, he shares them with the girls around him to help them grow stronger. He thinks that, with all these resources at his disposal, he is sure to prove his Dao, become an emperor, and ascend to immortality someday.

Until one day, he sees clouds of tribulation rolling across the sky, and several female emperors reborn in the midst of the lightning tribulation. The light slowly fades from Mu Zhian's eyes as he murmurs, "I was so naive, truly... I thought that after killing those chosen by heaven, I would become the protagonist of the new world and a mighty immortal ascender of the future. But I never imagined... that they were the protagonists all along."
