Showbiz: I Work as an Extra, Get Paid and Fed, and Earn an Internship Stamp

Su Yang transmigrated to a parallel world and, during his freshman-year internship as an extra on a film set, unexpectedly awakened the Talent Recruitment System! A war-of-resistance production urgently needs 300 Japanese soldiers who know a bit of Japanese. The pay is only 80 yuan a day? Nobody wants the job? I'll do it! Recruit 300 college students fluent in Japanese. It's fun, pays well, and includes meals. Only an idiot would turn this down! A gangster drama urgently needs 50 gang members with menacing faces who know how to fight. The pay is 50 yuan a day with three meals included? Nobody wants the job? I'll do it! Ugly college students, today's your lucky day! You get to experience life as a bad guy and hit on young women without breaking the law. How could you not sign up for something this fun? A hard-core sci-fi production urgently needs 10 graduate students in the basic sciences. Pay negotiable. Applicants must have relevant degrees and be able to offer ideas to fill in the technical details... Negotiable? That just means they're not paying, right? No problem! Just stamp my internship certificate! I'll do it! Recruit 10 graduate students from the physics departments at Qinghua and Beida... Wait, how did you end up bringing in a nationally renowned senior professor to verify the science? Thanks to Su Chen's incredible "connections," even though he can only land extra roles, nobody on the entire film set dares mess with him! A young star wants to put me down? Get lost. I can recruit someone else to play your role, and I'll pay them just one-tenth of your fee!
