In places like these, trying to investigate anything can truly be more difficult than reaching the heavens.
Unless the person who goes to gather intelligence possesses incomparably formidable strength, capable of overpowering the forces behind the Black Market.
Furthermore, they must find the person who had dealings with He Song.
Otherwise, even if one's strength is boundless, it's probably still difficult to find any trace of He Song.
In Luo Feng Province's state mansion, not to mention whether there is someone with such strength.
Even if such a powerful individual exists, he is unlikely to overturn an entire Black Market within Smoke-Cloud State mansion over such a trivial matter.
In such a situation, as long as He Song claims he purchased what he needed from within the Black Market.
Then, almost no one would have any objections to it.
Even, because of the involvement of the Black Market, there would hardly be anyone who would dare to ask He Song what exactly he purchased.
