Fixten

After Stargaze Family executed his family, Noel Ardagan embarked on his journey, restoring his family name with the help of a System. 

"What? How the heck did she get it before me? The system told me that I'm the only one who knows about it!" Noel Ardagan cursed in anger, "That conniving murdering woman!"

"At this point in time, only I should be aware about this tomb. But how did he find out about it?" Anna Stargaze, even after her reincarnation, couldn’t comprehend Noel's actions.

The clash between of a person holding a system and a reincarnator who knows everything in the future is about to start.

System vs Rebirth

"…" Noel thought for a moment and asked, "If I have to use a portion of my Spiritual Energy reserve to learn a new technique, doesn't that mean I have to be more careful about choosing my Spirit Abilities?"

"Not necessarily." Heisk shook her head. The Spirits were helping their master to improve, so even though she scared him about the possibility, Heisk had prepared for the solution. "We're the ones taking care of your Spiritual Energy reserve. That's why you haven't received any Spirit Abilities for a while."

"I see. But how can I know how much Spiritual Energy I do have and how much I have spent for the Spirit Abilities?"

"You can simply ask us. We're the one taking care of your Spiritual Energy, so if you ask us, we can make the rough calculation for you. For now, your Spirit Ability have taken sixty percent of your Spiritual Energy Reserve and forty percent are used for your consumption."
