The tent was brightly lit by a Magic Crystal Lamp that consumed magic crystals, allowing the mechanical camera to clearly capture the schematics on the table. Some mages noticed his actions, but they had no idea what a camera was, therefore they didn't understand what Cheng Ziang was doing. Whoever attempted to inquire was promptly engaged by Yalunte and treated to a drink.
After finishing everything, Cheng Ziang approached the entrance of the tent and signaled Yalunte to leave. After downing the last glass of wine, Yalunte left the group of drunkards, leaving the tent with Cheng Ziang.
