The system was momentarily at a loss for words,
"I... why should I teach you!?"
"Aren't you supposed to optimize and upgrade? With such a powerful flying sword, you must know Sword Control Skill, right?"
Huangfu Yi shrugged his shoulders and patted the stick on his back,
"Today is the seventh day, just like you said, exchange this thing for money, and I can trade it for skills.
First, pay off the money for the Five Immortals Sword, and if it's still not enough, you can credit me a bit more."
"Hmph..."
The system was silent for a while,
"There is more than one sword maker in the world, and each sect has its own Sword Control Skill. It's not clear yet, take it and see."
"Sure."
Seeing that the system agreed, Huangfu Yi flipped and climbed down the well like a monkey, stretched out an iron rod, slid through the bones, and with a hook, lifted the sword bag onto the rod and retrieved it.
