Halfway there, Gao Fei communicated with Xuan Jizi using Mental Power.
"The secret technique to alter memories is indeed very effective," Gao Fei said. "But I have some concerns."
"What are you worried about?" Xuan Jizi asked.
"I'm worried that He Hentian might regain his original memories in the future."
"That's impossible. Once the memory is altered, it can't be restored."
"Really? No hope at all?"
"Yes, human nerves are very fragile. Once damaged, it's difficult to repair."
"Then I'm relieved," Gao Fei said, finally able to let go of his tension.

He Hentian stopped and said, "Here, the treasure hideout is right ahead! Now you can have a good look."
"Oh?" Gao Fei looked up and nearly burst his eyeballs, asking in astonishment, "The treasure hideout you're talking about... is this the place? Are you sure there's no mistake?"
