With the time chamber now complete, Shiro glanced at how much it drained her mana and couldn't help but widen her eyes.
Even with her new mana realm and monstrous regeneration, she estimated that she couldn't even keep this room up for more than 5 minutes and that was pushing it.
The realistic guess would be around 2 to 3 minutes outside this room.
Looking at the magic circle, Shiro saw that she could turn this off whenever she wanted but turning it back on would require her to recreate the magic circle since everything will need to sync up again.
Drinking a mana potion to keep this running, Shiro quickly teleported back to training hall 1.
"You're back. Considering the spike in mana that I felt, you were successful." Nan Tian smiled as Shiro nodded her head.
"Yup. Though it's a bit hard to sustain the room. It's draining my mana at a rate that I'll be empty in 3 minutes or so. I'll be drinking quite a few potions today." Shiro shrugged.
