The students felt excited as they quickly realise that that was the exit portal. Despite the happiness, they were cautious when they stepped towards the portal.
While they carefully tiptoed to the portal frame while simultaneously observing their surroundings, Lee casually walked past them and went ahead.
"Children, being over-cautious is more problematic than being carefree."
With this, he placed his palm on the stone frame.
*rumble*
The stone frame trembled briefly and calmed down after a few seconds. At the same time, Lee could see that his Mana reserve had lost about 70 Mana.
'Did it just take away 70 Mana?'
[Don't ask me. Though I know about Lurelands, I too am a stranger to these events.]
'Sounds reasonable.'
