"Fellow Daoist Su, have you ever heard that the Ghost Realm possesses an ancient treasure known as the Judge's Seal?"
Su Taiping continued speaking, then turned to ask Su Shi'er.
Su Shi'er's thoughts stirred slightly, but he merely nodded calmly. "I have heard of it."
As for what the Judge's Seal represented in the Ghost Realm, he had no way of knowing.
Yet he currently held one of them in his possession. The ghost cultivator who had died years ago had once said that there were ten Judge's Seals in the Ghost Realm in total.
Once someone gathered all ten, they could trigger a supreme treasure of the Ghost Realm.
As for what that supreme treasure of the Ghost Realm was, Su Shi'er had no idea.

At this moment, Su Taiping's sudden shift to the Judge's Seal caught Su Shi'er rather off guard.
Thoughts raced through his mind, and in an instant, he realized something.
"Could Fellow Daoist Taiping mean that breaking this Ghost Qi Barrier requires the Judge's Seal of the Ghost Realm?"
Before Su Taiping could continue, Su Shi'er hurriedly asked again.
Su Taiping nodded lightly. "Correct. If my judgment is right, several ancient Ghost Realm artifacts, Judge's Seals, are hidden within this Ghost Cultivator's Cave Mansion.
"The Judge's Seal is recorded in the Ghost Realm as a set of treasures. They are interconnected.
"If we can find one of these treasures, we can use it to stir the Judge's Seals inside the cave mansion.
"In that way, whether it is breaking this Ghost Qi Barrier or using the Judge's Seal's power to let the two of us enter the Ghost Cultivator's Cave
