Qi, Mana, Lifeforce

The next one, Frostbite Den, was filled with many types of monsters, some humanoid, others just beasts. 

This would allow Alex to capture a variety of monsters. 

The last one, Serpent's Lair, was filled with serpents. 

What interested Alex here were the exotic resources that came from the serpents. 

If he captured many of them, he would be able to obtain his own source of various types of toxins and venoms. 

These would become great sources of income and experimental materials for Alex. 

After all, their toxins could be used for many things, not just poison. 

He could use them to make medicine or other materials. 

But his thoughts were cut short as a delicious aroma reached his nose, making his stomach rumble in protest. 

This made Emily chuckle, "Let's eat first. 

You're always like that; when deep in thought, you forget everything, so I ordered the food for you."
