Li Zhirui frowned as he watched them escape; it wasn't that he didn't want to pursue and kill, but they fled too scatteredly, and there were quite a few cultivators nearby. Excessive consumption of mana could very likely put himself in danger.

In this way, Li Zhirui encountered several attacks from Devil Beasts and ambushes by cultivators. With sporadic stops and starts along the way, by the time he arrived at the frontline where Shen Leishan clashed with Yin Wind Cave, several months had passed.
On the border of Shen Leishan, there were five Great Immortal Cities and more than a dozen smaller Immortal Cities, forming a long defensive line to resist the invasion of Demon Cultivators from Yin Wind Cave.
