"Capturing Monsters"

When Ainsley heard that from the 51st floor to the 99th floor, the betting chip would no longer be energy crystals, she almost fainted. 

I thought I'd just asked Zack for five-coloured crystals this time and play! 

The baby didn't know that five, six, and seven-coloured crystals were so precious that no one would take them out just to gamble at the casino. 

Thus, the term changed into betting one's treasure. 

There were already lots of appraisers at the gambling hall, ready to appraise the treasure's value for the gamblers. 

One could find rare potions used as a gambling chip, a unique herb, stones, artefacts, beasts, monsters, and so on. 

Of course, not many would bring live beasts and monsters, so they'd just offer the body parts. 

Not only the 51st floor and beyond were treasure paradise, tons of mercenaries, treasure hunters and collectors also mingled inside.
