Eight hundred thousand spirit stones was a vast fortune, even for the Heavenly Poison Sect with its tens of thousands of followers, whose monthly consumption barely exceeded ten thousand spirit stones. Such wealth could sustain the Heavenly Poison Sect for several years, by which time the invasion of the Worm Race from the Star River would likely be nearing its end.
As for the superior quality spirit stones that Tang Yi had obtained, he planned to give them to Lu Ren, He Bugui, and yes, Zhuang Bifan as well.
After all, these individuals were some of the few friends Tang Yi had made since entering the Cultivation World. Tang Yi would inform them about the Worm Race situation, and whether they wished to leave or not, he would give them some spirit stones. After all, it was an acquaintance made, and Tang Yi felt it was only right to offer what little help he could.
