Southern Miao people don't venture beyond their borders; heroes descended from Emei instead.
Li Shentong might have been holding back for a long time... what he was waiting for was the chance when Zhai Muzhi was far from the heart of Ba Shu!
After all, he couldn't develop a massive covert power like Maitreya; his manpower was limited, so how easy could it be to conquer cities and territories? Even the heroes of Liang Mountain, after breaking through the cities, had to squat back in the mountains, essentially turning into bandits...
Going directly to attack Chengdu, or quietly taking off Zhai Muzhi's head, might have been simple for Li Shentong, but he was wary of a venomous snake lurking in the shadows.
The Snow Eagle was an assassin. When an assassin was hidden in the dark, that was when their threat was most potent, so Li Shentong kept his restraint, waiting for an opportunity.
But a glorious military formation could be broken.
