A minute before Jason entered the second door, he had been pondering which one to choose.
The left one definitely had more treasures inside that radiated several mana colors at once, but Jason was somehow drawn to enter the one in the middle.
This caused Jason to have a slight headache but he just followed his gut feeling, as he didn't want to regret anything later.
Though he relied on his mana eyes more often than not, he was aware that something important could be missed if he solely relied on them.
The same could be said for Artemis in particular.
She radiated a distinct color that had been hard to spot amongst all the others and Jason had been extremely lucky to have found her egg before hatching.
Jason didn't think extremely weak colors or mana radiation could be seen through the wall. In the end, he followed his gut feeling, only to get surprised by a heatwave flooding his face, as he opened the door to the middle hallway.
