As the God of Time and Space, I Am Actually Unknown?

I got the law of time and space, but I actually have a systematic thing. Its function is not to let me have countless harems and reach the pinnacle of life, but to let me be a golden finger to help the beloved protagonist of heaven reach the pinnacle of life. After every time I assist a protagonist, I will be killed as a villain, and then go to another dimension, and so on. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
