Ireya pondered for a while and finally discovered where the problem lay.
Although she hadn't granted Li Yu the right to preach in Green Field, she also didn't stop the local populace from spontaneously worshipping Saturday, which created a loophole.
On any given day, Li Yu could completely omit mentioning Saturday but could keep demonstrating miracles on her territory, thereby attracting people to the territory of the Double Rest Sect, where all the subsequent missionary work could be finished, without breaching the agreement made between them.
Just like with Fitzwilliam now, who knew nothing at all about Saturday, yet because Li Yu saved his sister upon whom his life depended, achieving what other Churches and Gods couldn't, he had firmly resolved to convert to the Double Rest Sect.
Previously, this issue wouldn't be too serious, as most of Green Field's populace and the lizard people shared a blood feud and were equally wary of Saturday.
