Auther's explanation:

(You can skip this)

Summoning creatures does not an that soone can summon anything they want. The spell model gives all the attributes and abilities of the summoned "beings." If there is no well-defined spell model, what will be summoned is just a useless 3D image. But it is not easy to find a spell model that has all the characteristics one wants in their summoned creatures. If One still wanted a personalized creature, then they have to create a spell model by themselves, but it is usually tough to even learn an already invented spell model, so the difficulty of creating a model from scratch could be imagined.

Let's say if the difficulty of using an already available spell model is equivalent to cloning a creature, then inventing a spell model from scratch is equivalent to creating a creature out of thin air. So people who are not good at magic research and developnt can't do it.

In theory, it was also possible to create a spell model that can summon the King Kong; but to really do it, in addition to the knowledge of magic developnt, One is also required to fully understand the nature, attributes, abilities and principles of King Kong's body, and even the characteristics of its soul. There are also many things that can go wrong while creating such a high difficulty spell model, So it is not sothing Punk can do at this stage.

Of course, if the spell model has been already created, then One can summon any creature as long as their soul foundation can support it.

In fact, all the so-called "learning spell model" actually ant they could now operate it step by step according to the road paved by the predecessors, without knowing the fundantals principles.

Learning these principles will only be necessary when one wants to promote to the legend.

Finally! The author will not include King Kong or any other elents that do not match this story's the.
