After Ascending to the Throne, the Junior Sister Turned into Cannon Fodder

[Strong female + ceiling of female protagonist's combat power + pretending to be a pig and eating tiger + loyal dog] Once Pei Yunsu traveled to the world of cultivation, he worked so hard that he finally ascended. She thought she could just step through the void and return to her real home, but she was told that ascending meant sacrificing herself to work for Heaven? Absolutely not! What if he was thrown into another small world and merged with the heaven of the small world? There must be a way in this world to get her out of heaven and back to modern times. For this reason, Pei Yunsu quietly transformed into the lower world, just to allow the Son of Destiny to complete his mission as planned. What? The villain has awakened, and can retain his memory every time he goes back to heaven, so he still needs to rely on this to become a monster? It's nothing in front of her strength! The villain wants to strangle the Destined Child in the cradle? Pei Yunsu went up and died before the villain's plan could be realized! The villain wants to get rid of the boss that was originally used to upgrade the Son of Luck? Get her to lie down on her side! After escorting them all the way, the final battle finally came. Pei Yunsu faced many choices along the way, but she thought that she would never give up the goal she had persisted in for thousands of years. So, she won't regret it. But, who can tell her why there is a cannon fodder who says he will follow her forever?
