They traveled to Changkong City, where a collapse had occurred.
Sikong is dead.
But he wasn't completely dead.
Super-Advancement Honkai Beast – Chariot-class Honkai Beast – Temple-class Honkai Beast – even Valkyrie Kiana, Raiden Mei, Bronya – Sikong can transform into whoever he wants, provided that the other party kills him first.
Sikong: "Humans! I will protect them!"
Himeko Murata: "In a way, you look better as a Honkai Beast. If you dare to transform into me and do anything strange again, I promise I won't kill you."
Kiana: "Um... could you transform into a Honkai Beast so I can ride it?"
Bronya: "Bronya was here first, Sikong should have granted my request first."
Raiden Mei: "Kiana, Bronya, you two stop bothering Sikong and come eat."
