After the two students left, Dean collapsed back into his chair in exhaustion.
He thought for a moment, before contacting someone through the communication token. An old man who had a scholarly aura walked into the Dean's office after a few minutes.
"Greetings, Dean."
"Greetings. How is the research going? Is there any progress?" The Dean asked.
The old man sighed and shook his head.
"I am really sorry, Sir. We have already used up every metal puppet we have access to including the wristbands. But we are unable to crack it."
"Are the inscriptions and formations built into them really that difficult to crack?"
Dean asked.
"To be honest, the formations and inscriptions used are not exactly of the extremely high level. But they are arranged and implemented in such a complicated manner that even Peak Stage Divine Plane Cultivators will have a hard time dealing with them."
