Kapitel 2062: "Creating A Holy Phoenix" 

"I can definitely use the blood control ability and the love virus at the same time, but lightning ability is still unstable. I don't know whether it can be used or not." 

There is also the realism art ability.... 

"I will focus on blood control, lightning and love virus from charm ability, so realism art can't be used simultaneously with the other three abilities. Using three abilities at once is already my limit." 

Thus, they had to think of what they wanted to create through the realism art ability. 

"As long as the thing created by this ability is still in use, it will still need my energy, so I will probably consume a lot of energy for several rounds before my energy core shows signs of discomfort." 

So, it was possible to create many things with the realism art ability, but it also sucked energy faster than just creating one thing but a super powerful thing.
