The Month-Passing Before the Trial at the Red Snake Mountains.
It's been nearly a whole month since Yang Wei and Liu Yan agreed to lay low and avoid causing any trouble.
Yang Wei figured there wasn't much to gain from attacking the sect matriarchs anyway, even if he knew where they were.
Liu Yan had been an Outer Sect disciple in the White Serpent Sect for about four months now, while Yang Wei, or rather "Wu Mingyu", had been there for almost a month. He spent most of his time holed up in his house, immersed in cultivation and picking up pointers from Bai Suzhen on how to amp up his demonic cultivation.
Unless Liu Yan dragged him out, he hardly ever left his place.
