Chapter 40 Dong Lai Wearing the Red Pill_2

Many people think that alchemy should be the kind of project that takes at least forty-nine or even eighty-one days, and that it must be operated with a huge alchemy furnace while someone is constantly watching the fire and controlling the fire power...

Actually, if you think about it, you'll realize that these are all futile operations.

The temperature that ancient furnaces could produce was limited to begin with, many metals with high melting points couldn't be processed at all, and temperature control could not be very precise. If you drag the process out for dozens of days, what could you possibly produce?

In fact, in that era, if you burned something for dozens of hours and it still wasn't processed properly, burning it for several more days would be just as meaningless.
