The cultivators in the underground karst cave looked at each other for a brief moment. Then without exchanging any words, they headed to a random Array Formation engraved on the walls of the cave.
Tang Yin was the same, he headed to a random Array Formation. He had never really used Array Formation before, let alone decipher and create one. The most contact he had ever had with Array Formations was destroying them.
However, he was still fairly confident in passing the trial. This confidence stemmed from his memories. He had killed thousands of cultivators, he had made sure to use Soul Plunder on every cultivator he killed. There were definitely Formation Masters among some of them.
Therefore, although he wasn't certain that he had the most knowledge regarding Array Formation among the cultivators present, he was somewhat optimistic about his chances of passing this trial.
