Holy Sword and Demonic Sword

"Congratulations, host, you have advanced to level 9 cherub!

"Congratulations, host, you have advanced to level 9 chaos demon king!"

At this point, the system's voice stopped.

Davis was stunned.

What was going on?

How did his strength increase so much?

Before this, he was just a lord angel and level 1 demon king.

Now, he was only second to the seraph and the twelve demonic gods.

Was it because he saved Lea?

If it was because he saved the princess that his strength increased greatly, he would have to wait for the princess to be rescued by him.

Davis mocked himself in his heart and looked at Princess Lea in his arms with a complicated expression.

After Princess Lea retrieved her blood, her complexion had almost recovered.

Furthermore, when Davis accepted the sacrifice, she was also affected by it.
