The Birth of the First Camera

After dividing up their tasks, the two men quickly busied themselves again. Ao Fei went to improve his Photography Box, while Qu Bing went to the mechanical group to order a pile of Silver Plates for use as experimental materials. Fortunately, the research institute had ample reserves of all kinds of materials. Even Precious Metals like silver were available in sufficient quantities for them to squander.

The Han Tribe was not short on silver, and it did not use silver as currency for trade either. As long as the silver was not made into Silver Coins, it could not circulate on the market, so neither side had to worry about anyone embezzling these experimental materials.

After preparing the Silver Plates, Qu Bing once again went to the Chemistry Group to find Wen Nong, the group leader. He first asked about the news from Xingang Commandery concerning bullet-body materials and processing equipment for experiments. When he learned that they had not been delivered yet, he pulled Wen Nong into a discussion about his Photography Technique.

"Senior Brother Wen, the two materials you gave me can't be stopped once they start reacting. Is there any way—or some other reagent—that can terminate the reaction after they've reacted halfway, while also preserving the result for a long time?" Qu Bing asked from beside the experiment table.

Wen Nong stopped his research on Reagent No. 17 and asked in confusion, "Reaction? What reaction? Aren't you trying to make Silver Nitrate react? Why do you want to terminate the reaction now?"

"Exactly, to make it react. That Sodium Sulfite Solution you gave me really is useful, and it's already had some effect. But the reaction is too intense, so it still doesn't meet the requirements. I was wondering whether there's some way to make it stop
