After a while, Hei Xinjiu changed her mind and decided to leave immediately.
Jian Feng was confused. “Didn’t you say that it would be easier to leave at night? Why are you leaving now?”
Yun chujiu blinked her eyes and explained her thoughts.
She originally planned to leave through the entrance of the Earth fire main pipeline, which would be more convenient at night.
However, when she thought about it just now, there were too many unpredictable factors to leave through the entrance of the main pipeline. It would be best if she could leave through the exit of the No. 9 Forging Sword Hall. That way, she could appear in her dormitory without anyone noticing.
Then, there was a problem!
How could she know which of the many pipelines led to the No. 9 Forging Sword Hall?
The only way was to try it one by one. He would hide in every exit of the Earth Fire and listen to the voices outside. Eventually, he would find the pipes of the No. 9 Sword Forging Hall.
