Ji Yancheng has openly declared a threat to Su Xin, everyone assumed that Su Xin would certainly seek help from the Iron Family, but in fact, Su Xin was now at the headquarters of the Criminal Investigation Secret Agents.
The Criminal Investigation Secret Agents of the Six Gates pervaded everywhere, most of their intelligence was recorded in text form, but for some sensitive individuals, they used the Shadow Retaining Stone for record keeping.
Su Xin wanted to find detailed information about Ji Yancheng, but unexpectedly he found some rather interesting things, which added a bit more certainty to his prepared plan.
Normally, the various information from the Criminal Investigation Secret Agents was not allowed to be borrowed, let alone something as precious as the Shadow Retaining Stone.
