What do ancient books say about insect psychic?

Hello, there are few insects in thousands of traditional Chinese medicines in China, such as Eupolyphaga Seu Steleophaga, Aspongopus, Eupolyphaga Seu Steleophaga, Mylabris, Bombyx Batryticatus, Cordyceps sinensis, and so on. All medical people will answer that they don't have such a high standard of living, they only eat saprophytes and small insects; Cordyceps sinensis is the only insect that can treat nephropathy, but it is wild and cannot be artificially fed, so the only candidate has been ruled out. So I can tell you for sure that there is no such "rich worm" in the world; Precious medicinal materials are caused by factors such as low yield and scarcity, and Cordyceps sinensis is an example. That kind of bug either exists in martial arts novels or lies that hurt consumers.
