The method to refine the Golden Silkworm Gu is to separately collect a Golden Silkworm, a centipede, a small snake, a millipede, an ant, a poisonous bee, a cicada, and an earthworm—altogether twelve kinds of poisonous insects. Along with the refiner's own hair, they are dried and ground into powder, fed to the live Golden Silkworm, and placed before a Plague Tool, buried at an extremely spiritually energized crossroads.
After seventy-four cycles of forty-nine days, it is removed and stored in specially made censers, and the Golden Silkworm Gu comes into being.
This method of gu refining, is is recorded in detail in the Gu Refining Manual.
However, even with the Manual, Luo Bing failed to refine a Golden Silkworm Gu. After more than a dozen tries, each ended in a failure.
At the end of the day, Luo Bing simply was not proficient in using various methods of gu refining.
Chen Dengming was different.
