This old beggar is full of bluster, talking about destiny not yet arrived. This is clearly just an ordinary jade pendant, without a hint of anything miraculous, yet the old beggar has been hyping it up as something divine.
Thinking about cheating me, is pure fantasy.
"Oh dear, young friend, wait, the old beggar remembered wrong. This is an ancestral jade pendant of the old beggar's. True, it has been around for a long time, but indeed, it has no special features. It's the old beggar who remembered wrong."
"How about this, I have a Space Ring here. If you let me out, I will give you this ring with both hands."
From behind the rock, the old beggar continued his shrill, surprised screams. He hadn't expected to be seen through by someone at the first meeting and was somewhat embarrassed. At this point, he could only offer something genuine in hopes of exchanging it for his freedom.
