It Seems Everyone Likes Cheng Poli

It looks like a story about a golden finger, but it's really a found-family story where everyone likes the protagonist~ Cheng Poli, a person from Earth, transmigrates into a book world and accidentally binds himself to the System that was supposed to belong to the male lead. The System is a card-drawing System. In the original story, it was supposed to be the male lead's golden finger, helping him reach the peak of success in the mad world of the wealthy through card draws. Now, it can only bind itself to Cheng Poli and have him serve as the male lead's golden finger instead. The card-drawing System and Cheng Poli strike a deal: Almost all the abilities produced by Cheng Poli's cards must be used on the male lead to help him reach the peak of success as quickly as possible. Once Cheng Poli achieves this goal, he can collect his mission-completion reward. For the reward, Cheng Poli draws all sorts of strange cards and uses most of them on the male lead, helping him get through one "plot crisis" after another. Wait a minute... Why does it seem that, as he keeps doing missions, the male lead, the pet who was supposed to belong to the male lead, and even some minor antagonist are starting to act differently toward him? He's only a temporary golden finger, a System helper who's supposed to fake his death and disappear once his job is done. Updates at 6:00 a.m.! Love you all!
