As soon as Zhao Hai's soul entered the cauldron, he felt as if he had entered a strange world. In this world, there were unintentional magic formations that were constantly operating. Zhao Hai tried to imprint his soul power into one of the magic formations. The moment his soul power entered the magic formation, the magic formation immediately lit up. Then, Zhao Hai felt a connection between him and the magic formation. And this connection was like his with the undead, an unbreakable connection.
At the same time, a message was sent to Zhao Hai from the formation. The message included the method of using the formation and its usage.
Zhao Hai was overjoyed. He knew that he had finally refined a formation, and it didn't seem very difficult. Therefore, Zhao Hai immediately began to imprint his soul power into the formations.
