Improving the Qi Return Pill

Niu Huaqing imparted all the formations knowledge he knew to Ling Han, and Ling Han also absorbed it completely. His ability to digest knowledge was astonishingly strong.

This made Niu Huaqing very happy. As a Master, he liked disciples like this the most.

However, he only imparted experience and understanding, and did not teach Ling Han the specifics of formations. As long as he grasped the basic knowledge thoroughly, setting up any formations would be a piece of cake.

Niu Huaqing only planned to teach Ling Han a set of formations, which would be used to defeat the General Vajra.

However, this set of formations had yet to be fully formed. Niu Huaqing had obtained inspiration from a broken ancient formation and modified it, calling it the 33 Layered Vajra Formation.
