Within a mere month,
Wei Cheng had successfully refined his third Reflective Sky Lamp.
This was also his fifth Primordial Spirit Weapon.
When Wei Cheng put the last wisp of Dao Fire into it, all three Reflective Sky Lamps resonated together. It seemed as if this triggered some extraordinary mechanism, or more straightforwardly, it was the progress from quantitative change to qualitative change.
As if having grasp something, Wei Cheng carefully savoured their resonance, then went on to adjust them one by one.
That's because he discovered three reasons for the resonance.
The first was the Dao Fire, which was naturally attracted to itself. Since Dao Fire existed within each of the three Reflective Sky Lamps, it was only natural that they would resonate, but this only accounted for about 50% of the resonance.
