Bloodthirsty Charm logged off to rest as soon as he finished speaking.
"The mental exhaustion is actually this severe?" Shi Feng frowned as he watched Bloodthirsty Charm go offline.
After observing him for some time, Shi Feng could confirm that Bloodthirsty Charm was an expert of the Vacuum Realm. He would be considered a top-tier existence even in a super guild, which was why he had been so confident.
The trials within the Titan Library tested nothing but a player's skill, having nothing to do with skills or equipment.
If even an expert like Bloodthirsty Charm found it helplessly difficult, it was hard to imagine just how challenging the central area's trial would be.
Once mental exhaustion exceeded a player's limits, recovery generally took three to five hours. If one overexerted oneself, even resting for over ten hours would not be surprising. Even using an S-Grade Nutrient Potion for recovery, it would still take at least an hour in the real world to fully recover.
There were only three hours to choose skill books in the Titan Library. Recovering for an hour in reality meant two hours in God's Domain. By the time Bloodthirsty Charm returned, he would have practically no time left to challenge the central area.
"This trial is really ruthless!" Shi Feng clicked his tongue inwardly.
Failing once meant using up an S-Grade Nutrient Potion and being limited to selecting skill books in the inner area. Without an S-Grade Nutrient Potion to recover, it was equivalent to losing an opportunity to choose skill books in the Titan Library.
Only now did he understand why so many peak experts had stopped at the central area.
"Fortunately, I still have a few S-Grade Nutrient Potions. Otherwise, I probably wouldn't even qualify to challenge it." Shi Feng adjusted his mindset
