Whenever Xiang Yuan encountered a problem he could not solve, he would humbly seek his martial uncle's guidance. The latter had always given silently, never asking for anything in return—a model of a venerable senior with lofty virtue.

The grand formation here had been created by the Yellow Springs Saintess from moonlight, combined with the original illusion formation. It was not particularly ingenious in itself; its only standout quality was its eerie strangeness.
