Fan Meinan grabbed the bronze rings from the hands of the lady in shades, throwing it to Zhang Heng, coming down from the second floor.
[Name: Oath Rings]
[Grade: F]
[Effect: If one of the two bearers breaks an oath, the other will know about it.]
Zhang Heng obtained this Grade-F game item from Mr. Coffee during the previous quest. The identification results just came in that afternoon, and it happened to come in handy during the interrogation process.
The conditions of activating the Oath Rings were straightforward. All the wearer needed to do was mix both wearers' blood, write the vows on parchment, then put on the ring. If one were to violate the vow, the other wearer would be instantly notified—the ring of the one who broke the vow would start to heat up. Once the ring was removed, the oath would become invalid.
