While Amanet was gathering all kinds of intelligence, Liu Zhi had also brought some of his subordinates through the passage between Ghost Realms and arrived in this world.
After all, he had to come and take a look at what was happening in the Ghost Realm.
Getting into a Ghost Realm was simple. Between two Ghost Realms, there was something like a signpost.
The signpost stood at a crossroads. It indicated which direction to travel to reach another Ghost Realm, along with an approximate travel time in days.
