Having been "taught a lesson" by Ruan Yan silently, the students no longer dared to speak up to interrupt him, quietly listening to his lecture.
The classroom was very quiet, with only the sound of Ruan Yan's lecture, note-taking, and the turning of pages.
Even their breathing sound was kept to a minimum.
Ruan Yan's lecture was excellent, but his attitude was rather casual.
Today, he was covering "Reconnaissance Intelligence Equipment," planning to finish the entire lecture tonight. This included an overview, optical reconnaissance equipment, communication signal reconnaissance equipment, non-communication signal reconnaissance equipment, ground sensor reconnaissance equipment, aerial reconnaissance equipment, and space reconnaissance equipment.
The first few sections were the focus, while the latter would probably just be briefly introduced.
