The Witch with the Forbidden Ancient Book Is a Friend of the Black Tower?

[Not cool writing + not invincible + non-travel + original plot + private design + slightly OOC] One day, Black Tower received a message from Mio Yuan Star. After reading it, she knew who sent it. She then commissioned the Star Dome Train to go to Mio Yuan Planet to find Lingxi and bring her to the space station. When I first arrived at Mio Yuan Star, I stood in the observation car on March 7 and looked out. I accidentally saw what happened to Mio Yuan Star. But after leaving, she forgot about it. Although she prevented Walter and Dan Heng from going, it was to no avail, and eventually she went along. In Mio Yuan Star, the three of them accidentally triggered a mechanism, causing the three of them to be separated. While searching for a way out, Walter accidentally met Lingxi who had turned into a loli; Dan Heng found a sealed ancient book; and March 7th saw the coffin containing the holy body of the saint in that memory. Since then, the dusty taboo ancient books have been opened again, and the saint's coffin has been taken away by unknown guests. Heita: It's time for you to see the outside world, little sister from the countryside. Lingxi: You should go out for a walk more often, old woman Heita! When the holy church is no longer sacred, and the pure white skirt of the saint is also stained with a layer of darkness by the black abyss, where should the confused saint go? What kind of journey should the witch of disaster embark on? Bai Yuan: We have no way of knowing, we have no choice. This is our destiny, this is our destiny...
