Not only had he heard about it, but Zhuang Qing had personally experienced Lu Qian's Five Elements Grand Array. Knowing that Lu Qian was merely at Late-Stage Qi Cultivation, yet able to hold off two Foundation Establishment cultivators for thirty breaths, his abilities were truly astonishing, causing deep apprehension among the two people from the Spirit Talisman Sect.
The Spirit Talisman Sect also had an Array Cultivator, also at Late-Stage Qi Cultivation, but his array skills were mediocre and couldn't fully control their own Foundation Establishment level Mountain Protection Grand Array. He could only use some Qi Cultivation level methods to link the Foundation Establishment attacks of the Mountain Protection Grand Array, better than nothing.
According to him, studying arrays requires a high demand on one's Divine Sense. At Late-Stage Qi Cultivation, it's just the starting point for learning, so there's nothing unusual about it.
