Regarding the Seven Great Wonders, Jun Xiaoyao still has some understanding.
In the Immortal Realm, perhaps there are few who haven't heard of them.
The so-called Seven Great Wonders refer to seven mysterious legends circulating in the Immortal Realm.
For example, the legend of the Ghost Ship at the end of the starlit sky, where anyone who sees that ship, regardless of who they are—even a Saint—becomes enchanted and boards the ship, heading to the end of the Other Shore of the Yellow Springs.
Another is the rumor of the Beheaded Swordsman, a headless figure carrying a rusty, blood-dripping sword, wandering in a dazed manner through every corner of the Immortal Realm. Anyone encountering the Beheaded Swordsman, from common cultivators to Supreme Venerables, meets with doom without exception.
These various legends eventually formed the Seven Great Wonders.
It can be said that each wonder represents a secret of the Immortal Realm, deemed as taboo.
