Tang San did not go to scrutinize the treasures within the vault, instead, he first located the Main Control Array.
The Main Control Array of the Academy's store was situated at the innermost part of the vault, within a sealed metal chamber.
This metal chamber had no windows, and its door was shut tight. However, there was no longer an Alarm Formation to interfere here.
Tang San did not need to enter the small chamber that housed the Main Control Array. He placed one hand against the metal wall, silently perceiving the energy fluctuations inside, and with his powerful Spiritual Power, he memorably catalogued every trace of energy variation.
