Kain was hesitant to choose any of them. After all, he may have an idea of what their effect on Bea' evolution would be, but he couldn't know for sure until the evolution was completed.
Thankfully, he had the simulator.
Since the area was enclosed, he decided to briefly head into the Laboratory to see if he could use the GP he recently collected to run some simulations for Bea.
However, while several new evolutionary materials were added after their travelling during the missions, such as the yellow-grade Pterix Spiritual Power Orb, none of the mental-attribute materials he was currently looking at were in the System.
Kain realized that he must see an object in person before he could have it added to the Simulator.
Therefore, with hope Kain went to the only employee currently in the Exchange Hall.
"Is there any chance that I could see some of the evolutionary materials in person?"
