Qin Yi originally planned to stay for four or five days and then leave, but eventually stayed for about a week.
In the following days, Qin Yi was not idle at all.
Though he was tortured to the point of agony by Qin Mu and Ning Tian, he gained a lot, with rapid improvements in his cultivation and array skills.
All good things come to an end.
Qin Yi had to leave.
"Take this with you." Qin Mu handed Qin Yi a triangular piece of metal.
"What is this?"
"A Break Array Stone. With this, you can freely enter and exit the Heavenly Rift."
Qin Yi took it, "Thanks a lot!"
"I hope the next time you come, you can take that Immortal Artifact with you." Qin Mu said with a smile.
Qin Yi suddenly broke into a wide grin, "Why bother going to all that trouble? Anyway, with your cultivation, you don't need that thing, why not just give it all to me?"
