Jiang Yuan had the Information Collection Device at hand, so he wasn't very concerned about whether or not to sell the "charger."
Anyway, as long as he could take a quick glance from a distance, he could collect information and generate blueprints. At worst, he could ask Leng Yutang to help with the manufacturing... Also, he planned to ask at the gathering today if he could bind Leng Yutang, Hou Ze, the little fox, and others as guests.
With the system-authenticated binding relationship, it would feel more secure to use them in the future.
Unfortunately, Qing Niao seemed to have only heard of the treasure but never seen it, so there was nothing left in her memory now.
If she had seen it, he could directly perform a big data search for the treasure, and try if he could collect information from a distance. If everything went smoothly, he could achieve freedom in magical treasure blueprints without ever leaving his home with two divine artifacts!
