First Day In Game, I Got Ten Billion From Infinite Number Of Check-ins - Chapter 465 - Dizzy

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.

Now, I’m trying to save the world using the ‘System’ I gained as the ‘Regressor’s Privilege’… but the Main Heroines have also awakened their memories of the previous timeline.

God damnit.

A high-ranking Duke’s daughter, Roxana, and her fiancé, the crown prince.

Everything came crashing down when a Baron’s daughter Claire came between the two.

Honor, reputation, even her fiancé, the Crown Prince…..

In the depths of despair, the infamous Grand Duke Elvin reached out to Roxana.

“I can help you.”

It was a dubious proposition, but Roxana accepted it in the end……

The fragile and lovely Claire and the wicked Princess Roxana.

But who was the real villain?

MC (female protagonist) dies in a plane crash and wakes up in the body of a beautiful but corrupt and lascivious prime minister in ancient times, Zhang Qinglian. As circumstances decree, he (she) cannot reveal that the original owner’s soul is gone else calamity might occur. So he (she) decides to walk a righteous path, determined to help the lovely but simple little emperor rule the country. Not backing down after facing torture, not losing courage, destroying rebellions and facing off with scheming princes.
