Zhang Yu received the letter Tao Dingfu had sent three days later. There were no pleasantries in it, only a mention of the Threefold Origin Convergence method and a warning that Master Bai Xiu had very likely attained "Inner-Outer Illumination," telling him to be careful in this battle.
This was his first time hearing of such a method. Judging from the letter's contents, so-called "Inner-Outer Illumination" meant, in truth, "one's own Dao-heart was settled, and the Dao sought outside was made clear."
