All the Geniuses in My Study Group Are Real

Li Dong, an underachieving student, accidentally stumbles into a bizarre chat group called the "Azure Dragon Study Squad." All the members have old-fashioned names like Isaac Newton, Faraday, Gauss, and Einstein, and they frequently debate obscure academic topics while occasionally sending exclusive red envelopes. The contents of those envelopes are even stranger: "Focus that Pierces Truth," "Fragments of Logical Thinking," "Absolute Memory," "The Origin of Calculus"... Li Dong is convinced they are just a bunch of delusional role-players. That is, until one day, a member named "Isaac Newton" suddenly types in a trembling voice: "Gentlemen, while measuring the speed of sound, I have discovered that God seems to have hidden a variable in the air."
