The Humans were indeed the race with the highest Insight.
Under Jiang Feng's teaching, around thirty of them had learned Alchemy while the other fifty had learned Blacksmithing.
In order to have the Humans help him create more wealth, he even bought many tools for Blacksmithing and Alchemy. He had even created an Alchemy Atelier and Smithy for them.
After teaching the Humans the Craft-Profession Skills, he found a quiet place and entered the Qiankun Gourd to continue with his evolution. He was going to increase his power some more.
After completing the first round of quests for the Uproar in Heaven plot quest, he obtained another 30 drops of Divine Dragon blood. He now had 31 of them, and he was going to evolve once again and see how much it would increase his stats.
The purity level for this Shifter Emperor Bloodline was 5. After consuming 19 more drops, his Shifter Emperor Bloodline's purity had reached 100%.
