Many years ago, Wang Wei predicted the Karma Backlash he would face because he stole many people's luck using a shoddy method, and the fact that he was so weak.
So, he was prepared in advance and delayed the backlash for as long as possible. His original plan was to use the Origin Pill Dao Sect's luck to withstand that backlash.

However, another plan came to mind; he wanted to use this situation to get some answers regarding the [Flame Controlling Art]. And the first step in his plan was to drastically increase the backlash before transferring it to his third senior sister, Lan Ling.
Although doing so was taking a little risk, it was a calculated one.
