The Great Northern Emperor felt that his processing speed wasn't fast enough, as he clearly could not keep up with Song Shuhang's thoughts. Weren't they talking about defensive magical treasures? How did railings suddenly come into the picture?

The Great Northern Emperor asked, "Tell me, what are you going to do with a guardrail? Could it be that you want to make an immortal boat-like magical treasure?"

Song Shuhang shook his head. He took out a piece of paper from his spatial bracelet. On this paper was the design for the 'treasured saber with guardrails' that he had drawn not too long ago.

He had thought of several different types of guardrails.
