Tonight, Zhang Yanzong was both mentally and physically exhausted.
If Li Ziqi's theory was correct and the map Saint Gate had given them was wrong, the remaining question was whether the location of the endpoint was correct or not.
Li Ziqi depended on her memory to draw Honglu Island out. It was in the same location as the Honglu Island marked in the map given by Saint Gate. Their shapes were the same.
The terrain was the same as well.
There didn't seem to be a problem at first glance, but Zhang Yanzong was an intelligent person, hence, he could verify right and wrong through his thinking process.
If the location of Honglu Island wasn't wrong, it meant that the Saint Gate gave them the wrong map out of boredom? This couldn't be the case, hence, there was only one possibility left.
