"That won't do," Wang Mu said helplessly. "I'm too weak right now; I can't even lift you. You should stay by your master's side and cultivate..."
What could it cultivate by my side? After a few months of cultivation, I'm afraid it would turn directly from a Divine Grade Sword Spirit into a little fool...
The Little Sword Spirit fell silent.
"How about this..." Wang Mu thought for a moment. "When I also become a Sword Immortal like your master in the future, if your master agrees, then we can cultivate together, okay?"
"Really?" The Little Sword Spirit's eyes lit up.
"Really," Wang Mu nodded.
"Then you have to pinky promise me," the Little Sword Spirit said, very childishly extending its hand.
This little one is a bit similar to Yan Qingwu from the game, where there was also a little plotline involving a pinky promise with Yan Qingwu.
That was on the eve of a major decisive battle.
