บท 674: Chapter 480: Yesterday's Beauty Becomes Today's Sister-in-law (4k)

Early in the morning, Zhou Dao had already entered the library of the Demon Control Department.

After all, the ''Demon-resisting Agency Work Manual'' is not omnipotent. Some secrets are not recorded, such as the Spirit Refining Furnace that Zhou Dao is most concerned about.

He had just witnessed the magic of this treasure last night, where the Six Ding Divine Fire Cover and the Great Spirit Thunder Pool merged into a first-rate magic artifact - the Thunderfire Wings.

The power of this artifact far exceeds any he has seen before, boosted by speed, and wielding the same power of thunder and fire. An average [Returning to Origin Realm] strongman would not be able to withstand it at all.

Naturally, Zhou Dao wants to study the Spirit Refining Furnace thoroughly.
