Although Elder Si was very reluctant, he had no other choice. He could only grit his teeth and sit down cross-legged.
He mobilized all the internal qi in his body and densely covered his body. Then he began to circulate the protective method.
This method was called the Thunder Protection Seal, a secret technique passed down from one generation to another in the Si family. It used the Si family's unique power of thunder as the core, combined with the research and cultivation results of the Si family's ancestors over thousands of years, and turned the power of thunder into protective magic power.
Elder Si used this technique with all his might. In an instant, the power of lightning was drawn from his body and condensed into the Thunder Protective Seal.
The shape of this protective seal was like an ancient talisman. It was engraved with dense lightning patterns as if it was an ancient book that sealed the endless power of thunder.
