Although the talk had gotten to this point, Sun Yixie, out of caution, still didn't untie Kang Haijiao.
He had Lin Yuancheng fetch a Japanese blade from Temple Island and had it stained with blood from the island, then together they escorted Kang Haijiao to his residence.
The place where Kang Haijiao lived was not the bustling inn but a nondescript private residence in the suburbs.
The house looked very simple, with just a table for dining and a bed for sleeping, almost devoid of any decent furniture—a place where even thieves wouldn't bother stealing anything.
However, it was precisely such houses that were good for hiding things.
To cut a long story short, it wasn't until Kang Haijiao revealed a hidden compartment beneath a floor tile and had Sun and Lin verify the presence of three swords that Sun Yixie finally untied him.
