The entire Heavenly Mechanism is shielded.
Even at the junction of the Zhenmang Zone and the Xihe Zone, space-time heavy artifacts are constantly fluctuating, causing the space-time rules there to be chaotic. Even utilizing the Space-Time Altar cannot traverse through.

Everyone likes to surprise their opponents, utterly defeating them in one battle!
