He would have been content with the Dao Fetus if he could only cultivate really fast, but the Dao Fetus also granted him Domain Power, which amplified his power by squaring it.
He used the extraordinary power to absolutely demolish every Rank 2 peer he encountered and even killed many Rank 3 cultivators. This was how he was able to get enough lifespan to speed up his cultivation so fast.
But then the Dao Fetus upped the ante by giving him an extra set of attributes and essentially doubling his stats. It practically turned him into someone Rank 4 cultivators couldn't kill despite being at Rank 2.
Because of his newfound power, he transformed from someone at the bottom of the barrel into a predator that other cultivators had to respect. It gave him a grand purpose and the hope to rise to the top of the world one day.
