After He Kao took the elixir with Xing Rui last time, his Alchemy Cauldron Skill progressed beyond Tier Three, and now he has successfully advanced to Tier Four.
In the eyes of others, this can be considered rapid advancement, but for He Kao, it's not too surprising, because he already had Tier Five cultivation, with the Insect Concealment Skill as his foundation; the Alchemy Cauldron Skill is merely an auxiliary practice.
He Kao's cultivation has never slackened. After breaking through Tier Five, he must experience a state wherein every movement and rest becomes cultivation, and further, he must train various applied techniques to the point where they can be executed instantaneously.
In his spare time, He Kao also participated in the construction of Floating Colors Grotto Heaven, assisting in the creation of grotto buildings and various landscapes, which also served as a honing of Divine Power.
