Zhang Yu spoke at length with Daoist Zhengqing, gaining some understanding of Laiyuan Way. After Daoist Zhengqing departed, he stood alone in the hall, deep in thought.
As for how to wage war against Origin Xia, having personally come to Origin Xia and gathered a great deal of information about it, he already had a preliminary judgment in mind.
Previously, he had discussed several outer worlds destroyed by Origin Xia with Daoist Sui and gained a general understanding of the conditions within those world-domains. Though they had not touched on the specific battles, he had nonetheless glimpsed many things absent from the records.
