The hardest challenge in spider breeding was how to prevent the spiders from cannibalizing each other. Only by solving this problem, one could breed spiders intensively within a limited space. This issue had always been a problem that domestic entomologists were trying to solve. When Liu Shiqing instructed Fei Yujiao to establish Galaxy Spider, he directly told her the solution. Once Fei Yujiao tried it out, it indeed worked perfectly. It was because of this that she dared to breed so many spiders in one workshop.
To keep this secret, Fei Yujiao came up with quite a few solutions, including the installation of cameras, signing confidentiality agreements, which were relatively modern methods, as well as more primitive methods like tearing off the label of the gamma ray machine, and scratching off its scale.
