Draco and Eva continued to cultivate like this. Even though they had experienced an epiphany on where next to take their power, they still had to fully understand this system before trying anything funny.
Draco had already studied the makeup of all the Qi Stones in this world, from impure to 9th grade, and could now replicate them with Refinement. This was the first step, but Draco and Eva were not in a rush.
This Martial Spirits World should be the gimmick for the fourth set of floors, so up until the 40th floors, and they were only on the 34th. They would likely encounter more of this world in later floors, so they stuck to what they should do now.
They focused on observing their Martial Spirits and trying to understand how they converted Qi into Dragon/Phoenix Qi. With Control Tier 5, Draco and Eva could see into the atomic realm, so they were able to catch something of the process.
