Liao Hanxue nodded understandingly at Duanmu Luolan. "Your idea is excellent, and I support your decision to install a backup barrier. So, what level are you in formation arrays?"
"Haha." Duanmu Luolan took out a formation array and showed it to Liao Hanxue, surprising her a bit. "I reached rank 10 array master a long time ago, Senior."
Liao Hanxue read the formation while nodding several times. "This formation array is indeed for a rank 10 array master, but the grade is too low, and it is too weak for this realm. I had never descended into the Three Mortal Realms before Zhang Fei took me there a few days ago, so I want you to tell me about the array grades that exist there."
"There are only five grade arrays in the Three Mortal Realms." Duanmu Luolan then mentioned them one by one.
