"Indeed." Huangfu Ruiling nodded. "However, the heads of the major families or core disciples are not subject to such strict restrictions. There's too much going on in these big families to impose stringent rules on them. Of course, if they wish to leave the Hidden World, they still need to report to the Enforcement Team."
These rules were similar to the immigration and customs regulations in the mortal world. However, they were stricter for ordinary disciples and rogue cultivators, while more lenient for the heads and important members of large families.
It was due to the reporting requirement that Huangfu Ruiling came to know about Ye Hongxuan and Lian Mengzhu's presence in the mortal world.
Ye Leng'an sighed helplessly. "Well, I just don't want to deal with them anymore."
