The item handed to me by Weichi is probably a Divine Seal Fragment that was gifted to him by the Divine Light in the past.
At this stage, having one more or one less Divine Seal Fragment doesn't make much difference to me. However, with the mindset of having more is better, I still decided to collect it, and casually asked, "Haven't you bound with this Divine Seal Fragment?"
"Binding with just one more Divine Seal Fragment wouldn't help me defeat the Old Fist God. Also, it's necessary to guard against the possibility of the Master of Divine Seal taking all my accumulated fragments halfway through via the binding connection. So, I didn't rashly do so," Weichi said.
Taking advantage of this opportunity, I also asked what method Master of the Divine Seal Tai Sui had entrusted to him to defeat the Old Fist God, as it might help me in dealing with Shan Liangyi. He openly shared it with me—due to the complexity of the method, he could only explain it in a way I could understand.
