I! Chicken Eating Devil

My name is Lin Cheng, and I am very panicked now. Because I traveled through time and got a golden finger. It's just that this cheat is a bit tricky, because he doesn't have a big gift package for newbies, nor does he give away a lottery as soon as he comes. After many years of reading novels, I know that the protagonist will definitely get some kind of opportunity as soon as he comes, or there will be some gift package from the system that will make me instantly awesome. But this awesome system was not given to me! I want to complain about it, what number should I call? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
