Cultivators travelling indeed face more troubles than ordinary people.
Although Boss Fatty doesn't hold any overt power, it's clear that his network is vast and complex... Lin Yuan even suspected that he may have some collusion with certain people inside the Eradication Department.
The Eradication Department is indeed very united.
But this unity is only present when facing Cultivators; then, they fight side by side, leaving no room for selfishness or scheming.
However, in daily life, casually selling some inconsequential information in exchange for some funds to pad their own wallets is a different matter altogether.
After all, unclaimed benefits expire eventually.
Otherwise, it's impossible to explain why Boss Fatty could know so much about the Flame Light Banner, which had only appeared once.
But even with his connections, the journey to the Cultivator gathering for Lin Yuan and Zhai Xing turned out to be much more complicated than imagined.
