Zhao Hai was not unfamiliar with metal puppets. He had been studying them when he was in the lower realm. The sea exploration sect had also used a large number of metal puppets to fight their enemies. To be honest, Zhao Hai looked down on the development of the arrays in the upper realm. The arrays in the upper realm were really poorly developed. They were far inferior to the sea exploration sect.
Although the spiritual array sect had obtained the method to insert the yin spirit into the array, this was the only method that could catch Zhao Hai's attention. The other arrays were not that impressive. There were still some redeeming qualities in the method of inserting the array into the Dharma, the dantian, and the sea of consciousness. As for the other methods, the spiritual array sect was really nothing special. An array sect that did not even have energy lines was nothing special.
