"An... invitation?"
Otto froze for a moment after hearing Xu Yanwu's words.
"Xu Yanwu, are you sure that was... an invitation?"
"From the passage opened by the Second Divine Key, from that World Bubble?" Otto sounded somewhat astonished. "Are you certain?"
"I'm certain. I'm not crazy or stupid, and whatever's on the other side isn't some indescribable thing that bewitches people... Forget it, I can't say for sure without actually meeting him."
Xu Yanwu spoke from the other end of the communication. "He's inviting me over. I can feel that Durandal has already been invited over by him."

"Make preparations."
Otto spoke to the scientists of Schicksal. "Prepare for a second energy charge."

A few minutes earlier.
Xu Yanwu had personally watched Durandal disappear into a spatial rift.
