Commander Xin, eager to equip his army with weapons, naturally wanted a Wind-Powered Automatic Forging Hammer as well, so he accepted Elder Jin's suggestion and began negotiating with the Han Tribe's emissary group, asking them for these technologies.
The emissary group's attitude was unclear. They neither agreed to provide them nor explicitly refused, and the two sides began their usual wrangling. Naturally, all of this was cover for Beast Tooth's intelligence transfers to Elder Jin. Every few days, Elder Jin would visit the emissary group to meet Beast Tooth. His public excuse was to seek the technology for the Automatic Forging Hammer, but in reality, he was repeatedly revealing the Xin Tribe's defensive arrangements to Beast Tooth.
Elder Jin's frequent dealings with the Han Tribe's emissary group naturally aroused Commander Xin's suspicion. In truth, he was merely anxious; it was not that he genuinely distrusted Elder Jin. Rather, Elder Jin had gone to negotiate so many times without making any real progress, and Commander Xin was naturally worried.
Whenever this happened, Beast Tooth and Elder Jin would put on a duet, revealing a little of the technology while demanding a hefty payment from the Xin Tribe's upper ranks: a certain amount of Copper Ingots from the Xin Tribe.
They would exchange Copper Ingots for the Windmill and waterwheel technologies, while making it clear that these were merely agricultural water-lifting devices or mill-type Windmills and waterwheels. As for the Automatic Forging Hammer type, the emissary group refused to provide it no matter what.
