The Memory Bead is a very common magical treasure in the cultivation realm.
The Memory Bead in Han Youdao's hand, although only Tier One Lower Grade with the effect of recording surrounding images, is in high demand among cultivators.
Whether it's recording battles, lectures by high-tier cultivators, alchemy and artifact refining, talisman making and arrays, all require the use of the Memory Bead.
The images recorded by the Memory Bead can be completely preserved for about a hundred years.
Memory Beads of higher grade can preserve images for much longer, a thousand or ten thousand years is not a problem.
Seeing Han Youdao take out a Memory Bead, Lu Changfeng didn't find it particularly remarkable, as he had a few of them himself.
