The item I identified is very strange.

Xia Fan transmigrated into the body of an old man, running an underwear shop. Beautiful young women frequently visited his shop, but unfortunately, he was too weak to do anything about it; he could only watch. In this world of martial arts, only by becoming a martial artist could one hope to increase their lifespan. He tried countless methods, all to no avail, until today, when he suddenly saw a message appear on Chen Xiaoxue's exquisite little leather shoes: 【Identification: Top-grade Blood Qi Jar, containing a large amount of blood qi.】 Hmm? This identification method seems very strange!
