The stingy system of a shady dealer, only granting her three minutes of use time after she painstakingly finished studying a book, was too outrageous!

But verbally, it said in a considerate manner, "Host can study within the system, so it won't interfere with your sleep time."
Jiang Mianmian snorted, "I'll study on my own during class."
