Healing...

'This is bad...' Lucifer thought as he felt his head being massaged by a pretty woman.

Of course, Lucifer didn't care if Rachel was beautiful or not. Lucifer didn't give a fuck about something so mundane.

However, this situation was really bad as Lucifer was sure that he hadn't gotten any injury.

He hadn't gotten any injury or even a scratch from the old man or Professor Malbath's attack.

The old man was not that powerful, and he was a lot weaker than Sebastian. 

That was why Lucifer was sure that he hadn't gotten anything from the old man's attack.

And what's more, Lucifer...felt nothing at all when the old man attacked him. Absolutely nothing.

In fact, he felt as if the wind blew on his body, and that was it.

That was why Lucifer knew that Rachel wouldn't be able to find anything on his body.

And once Rachel founds it, Lucifer would immediately be suspected once she reports it to the old man.
