Survival

"Good. For. You," Britney said, annoyed that he was making progress while she wasted three months of her time.

"I told you it wouldn't be easy," Jayce replied as he released all of his spells.

Not only was she irritated from no progress, but she was also constantly on the verge of suffering from mana exhaustion.

Since Jayce always activated his demonic energy through the system, he needed to put a few safeguards in just in case.

One of them was that Britney would drain almost all of her mana, right before she would get mana exhaustion.

This was in case she somehow accidentally used both her mana and demonic energy at the same time, making herself implode.

Yet, because of this, she always felt exhausted and tired, which wasn't helping.

"You need to get angry, furious," Jayce said for he didn't know how many times.

"I am angry!" Britney yelled back with a snarl. 

"No, you're not. You're annoyed, like you stubbed your toe."
