The Dao Sect's mountain gates were completely enveloped by the Mountain Protection Array.
From the outside, the entire Dao Sect was shrouded in clouds and mist which formed a shape resembling a giant tortoise shell.
This is the Great Array formation that could be formed after achieving the Ten Base Formation, also known as the Array Formation.
The Great Array of the Dao Sect is named the Ten Directions Xuanwu Formation.
It was built by the Heavenly Mechanism Sect for the Dao Sect, perfected over countless years, to have today's form.
The Dao Sect also has its own Array Masters; such a massive Mountain Protection Array needs regular maintenance and cannot always rely on the Heavenly Mechanism Sect.
It's like putting the sect's safety completely in the hands of others.
Even so, the Mountain Protection Array built by the Heavenly Mechanism Sect still carries risks.
Now, these risks have emerged.
