Although Chen Lingyun's face was visibly flushed with warmth, Yan Yu did not get distracted because of that, still calmly observing the entire scene.
The four Yin Ghosts chosen by the opponent each held a different magic artifact. The white impermanent's pipa sword melody was for long-range attacks, the black impermanent's ghost-painted iron umbrella was for close-range defense, the horse-faced giant sword was for close-range attacks, and the ox-head's pagoda could emit large swaths of spiritual light, which seemed more like a type of magic artifact similar to the Xuan Guang Ruler, capable of both defense and control.
This combination perfectly confirmed Yan Yu's thinking: he believed that an Envoy Cultivator, especially one who played with ghosts, didn't need to excel in any particular aspect, but had to be sufficiently versatile.
