For a moment, the atmosphere outside the Sacred Puppet City's transport pavilion became very awkward. Everyone stared dumbfounded at the two men who put their hands on each other's shoulders. Many couldn't believe that another man had touched the puppet belonging to Lu Yu, who was a genius of the Nether Puppeteer Clan.
To Nether Puppeteers, their puppets were as holy and inviolable as virginity. Under normal circumstances, they wouldn't easily reveal their puppets. For example, Lu Cheng only produced his puppet during battle.
However, Lu Yu copied that top genius of the Nether Puppeteer Clan, so he carried his puppet on his back. The reason they gave to explain the behavior was to promote the spiritual connection between them and their puppet, and ultimately improve their control over it. In fact, they did so to show off.
For Nether Puppeteers, this was very cool, but in the eyes of experts from other clans, it was no different from exposing one's virginity.
