Jian Wushuang, as the top Dao Lord of the Ancient Court and possessing the strength of a fifth-tier Dao Lord, personally oversaw the underground chamber.
In addition to him, there were three other Dao Lords and hundreds of top-tier cultivators in charge of guarding the imprisoned cultivators.
Originally, they were all allies.
But now, they were imprisoned here.
The Ancient Court's explanation was that a certain crisis had occurred within the underground chamber, and everyone had been infected. They were told they needed to stay there, but in a thousand years, they would be free to leave.
These people actually believed it.
Guardian Yunhai had been observing all along and knew exactly what Jian Wushuang was planning.
It was highly likely that after the army made its move, he would kill everyone here.
This was to erase all their memories.
Not only their memories but their very existence needed to disappear.
