Wei Wuxian rolled his eyes. "Yes, and it is the only way to get him to move. String, stick, apple."

"He doesn't pull a cart, he just has to carry me, and I'm not that heavy. He's just a lazy donkey. Unless he wants something, then you can't get him to stop."

Wei Wuxian sighed. "I cannot do it right now, or I would show you. The Cultivators of my world have a Golden Core. Basically it is spirit power. As a junior you meditate many hours to create it and strengthen it, then you learn how to manipulate things. Spells, riding your sword, dealing with the undead and spirits, things like that."

He paused a moment, then smiled at the elf. "My new body...the previous owner never spent a lot of time working on his Golden Core." He cocked his head to the side and back. "If he had, he probably wouldn't have needed to summon me, so while I am critical, I understand...if it didn't happen this way, I would still be dead."

"But! If you want to see it," he grinned again, "Lan Zhan is very good at it. When we were in the caves, going down to help the Dweller, he gave me a lift so I didn't have to climb. He's the best husband ever."
