The Blind Man truly vanished so irresponsibly, leaving behind only one sentence: "Store the Heavenly Book in the ring, and don't take it out easily."
Zhao Changhe collected the Heavenly Book back into the ring with an aching head, deeply in contemplation.
Though they called him the Enigma, actually compared to before, this time he not only took action, but he also spoke quite a bit.
The Token is a sword-casting material, still missing a Night Sand. Although Xuanwu's records listed the needed materials, I couldn't recognize them, heaven knows what they are, and what material is the Token? The Blind Man's words gave me a clue all at once.
And the ring is a personal token of Emperor Ye, according to the description "used before achieving Dao," it might not represent the power of Emperor Ye, but at least it belongs to a "personal seal," able to represent an individual. The Token back then also could represent a single mission, but now it's meaningless.
