Typically, before opening the portal, Silver Snake Valley would activate the Heaven Reflecting Mirror to check the outside surroundings and confirm there is no ambush from the Corpse Race.
To avoid any potential exposure this time, they did not activate it in advance.
Lu Ye and Ying Wuji, the two outsiders, were naturally unaware of this.
As Chu Ruoyu finished speaking, the cultivators standing guard joined forces to summon a treasure resembling a bronze mirror, channeling their spirit force into it.
Soon, ripples appeared in the bronze mirror, resembling the rippling effects when stones are thrown into a calm lake.
As the ripples stabilized, a bird's-eye view of the outside world appeared in the mirror.
