Chương 390: Returning (3)

Shen Tianyu understood her meaning and began to explain in a low voice as they moved. Recording orbs were similar to jade slips but differed in their number of usages. Neither had a limit in how much they could record but a jade slip can only record one person's message and after it has been used, it will not be able to hold another person's message, though it can be viewed by a number of people. One must erase the previous message to reuse the jade slip. That's why cultivators prefer to use it like paperless letters.
