Previously, Lu Yi saw extremely mysterious array patterns at the exit of the East Forest Ruins, and it was only after absorbing the Array Tao inheritance and top-tier array analyses provided by the Heavenly Palace that he came to understand some of them.
All those array patterns were involved in space teleportation, capable of connecting to the void and traveling through it, a type of ancient transmission array pattern.
According to terms from his previous life, they were called transmission arrays.
Lu Yi, with his understanding of array patterns, could confirm that the exit he encountered at the East Forest Ruins was indeed a teleportation array.
However, perhaps due to the passage of time, the teleportation array had malfunctioned, and eventually it was possible to open it from the outside world to lead cultivators out of the East Forest Ruins.
