The next day, Zero woke feeling more energized than ever. After he took care of the three thieves, there were no more people trying to attack him.
Lilith was still sleeping on the side he was looking at. However, he was no longer worried as he had already found out the problem with Lilith being unconscious. Due to him absorbing Dark Energy from Lilith, she was suffering from a lack of mana. And for some reason, her body was no longer absorbing Dark Energy which led to her sleeping.
Lilith's problem could be easily solved if he transferred Dark Energy into her body, but he refrained from doing so for fear of creating additional problems. He was only willing to try this in the Tower Of Obelisk where he would be alone with her.
