For the other players, it's definitely a sky-high price!
To refine an array disk, it takes twenty drops of essence blood. After it's refined, teleporting back to reality might cost another considerable amount of essence blood. It's hard to say how much essence blood would be left after all that.
At this time, the middle-aged man said again, "I can refine the array disk, but I don't know the array patterns on it. You can only engrave them yourself. You need to wait here. When the basic structure of the disk is refined, I will call you."
"Alright."
Su Nan nodded, handed over twenty essence blood points, and the middle-aged man took the materials and turned to enter a secret chamber.
Now, it was time to wait.
Of course, Su Nan was not going to wait idly. His eyes looked at the foreknowledge ability.
"Perfect opportunity, use this chance to obtain information about The Land of the Lost from the Tiangong Pavilion."
