Transmigrated to the Qin Dynasty: The System Makes Me Complete Tasks

He accidentally transmigrated to the Qin Dynasty with the System. The System assigned him a mission: change the fate of the Great Qin, which was doomed to fall after only two generations, and he could go home. To earn points and upgrade the System, he helped an old woman catch chickens and a man push his cart. Even while being pursued, he never forgot to complete the System's missions. But the damn System won't let him speak up and reveal what happens in history ahead of time. Just because it won't let him talk, does that mean he can't reveal history? No one can stop me from making my way home.
