Is the Witch with the Forbidden Ancient Book a Friend of Herta’s?

【Not a power fantasy + not invincible + no transmigration + original plot + original settings + slight OOC】 One day, Herta received a message from the planet Lingyuan. After reading it, she knew who had sent it. She then commissioned the Astral Express to travel to Lingyuan, find Lingxi, and bring her to the space station. As soon as they arrived on Lingyuan, March 7th stood in the observation car and gazed outside. By chance, she saw something that had happened on Lingyuan in the past. But after leaving, she forgot all about it. She tried to stop Welt and Dan Heng from going, but it was no use. In the end, she went along too. On Lingyuan, the three accidentally triggered a mechanism and were separated. As they searched deeper for a way out, Welt happened upon Lingxi, who had turned into a little girl. Dan Heng found a sealed ancient book, while March 7th saw a coffin containing a saint’s body from that memory. From that moment on, the sealed forbidden book was opened once more, and the Nameless took the saint’s coffin away. Herta: You should go see the world outside, little country girl. Lingxi: You should get out more yourself, you old woman Herta! When the holy church is no longer holy, and the saint’s pure white hem is stained black by the abyss, where should the lost saint go? What path should the calamity witch take? White Kite: We cannot know. We have no choice. This is our fate, this is our destiny... 【The synopsis doesn’t do it justice. Please read the story itself.】
