My Brother Asked for Help, and My System Arrived

The male lead was born in Huaxia and transmigrated into a parallel world! He was planning to lie flat! Then his drunk friend called the wrong number and got through to him! The System arrived! And the System is incredibly powerful! The bar is about to go under? No problem, I've got this. The crime boss's heir? No problem, even he has to call me big brother. The story goes full throttle from there!
