Jiang Daozhen's plan was to first lay a solid foundation for He Kao, then find a way to pass on the entry-level technique of the Insect Concealment Skill, waiting for Zhou Du to transfer the Hidden Moth identity to his son... He, the elder, could afford to wait.
The best time to impart the technique is precisely the moment He Kao receives the Hidden Moth inheritance. Receiving the Hidden Moth object and accepting the inheritance doesn't make one a Hidden Moth immediately; a process is still required.
This process could be long or short; a prodigy like Huang Xiaopang took only a month, while someone with average talent like Xiaopang's father, Huang Cankui, took nearly half a year.
If during this process one practices the Hidden E Technique, when the portal to the Hidden Moth Space opens, it'll signify the entry-level mastery of the Insect Concealment Skill.
