Zhao Gongming's "Controlling Thunder and Lightning" can only be copied by seeing it in person; obviously, videos won't work.
Of course, there's another way, which is to find students from the fifth or sixth year at our school who are Thunder Attribute Skill Card Masters and have them use a Thunder Attribute Skill Card to help replicate for Zhao Gongming.
But Jiang Yuan doesn't know any students from fifth or sixth year.
The biggest downside of social anxiety is not wanting to bother others; if something can be done independently, he would definitely not seek help from others.
Obviously, going to the Elemental Spirit Clan's Grotto Heaven would suffice, and if not necessary, Jiang Yuan wouldn't seek help from those senior students.
The main issue isn't just Zhao Gongming, but also Shi Ji; whether it's Necromancy Skills or Illusion Technique Skills, Shi Ji is better than Zhao Gongming, capable of self-study and development.
