The old man looked at Li Lin and smiled slightly, then said in a hoarse voice, "I didn't expect you to be so meticulous, little friend. How did you figure out that the magic robe I am wearing is made of Celestial Xuan Silkworm Silk?"
Li Lin replied, "I once saw a description in an artifact-crafting manual that matches your robe precisely. Furthermore, just now, when I used my Divine Sense to probe your Dantian, I found that my sense could pass through smoothly only at the tear in your clothes, while everywhere else it was bounced right back."
The old man nodded, unbothered that his secret had been seen through, and completely unconcerned about being killed for his treasures.
