The Most Powerful Vampire in History

Su Ming was reborn as a bat. He thought he would be an ordinary bat in this life, but suddenly a system popped up and told Su Ming that he was not a bat, but a vampire. But this is not the most important thing. The most important thing is that this system is called the most powerful vampire system in history. However, this system is very unfair. It is called the most powerful blood-sucking system in history, but it still lets him do things to save the world. Is this what a vampire should do?
