In this world, no wall is completely airtight. Even though Ji Ziyan was very meticulous, how could people possibly keep a secret completely?
Unless they're dead!
But even if a dead person can keep a secret, many things can still point to them.
And what Xiao Jiu found out was some evidence directly pointing to Ji Ziyan, and then Xiao Jiu had someone continue to investigate further, but what he found was a dead end.
It could be said that Ji Ziyan had already killed everyone who knew the details, completely silencing them, but one person left some information, which was found by Ma Yingjun, whom Xiao Jiu had sent out.
What Xiao Jiu is telling Ye Xunhuan now is completely evidence-based. As for Ye Xunhuan saying Ji Ziyan must pay with his life, Xiao Jiu wasn't surprised in the least.
In fact, if it weren't for waiting for Ye Xunhuan to wake up, Xiao Jiu would have already acted against Ji Ziyan, making him pay with his life.
