The system's concept underlying this novel is geometric shapes.
Expect lots of intriguing stuff based on geometry!

Each element will have its own dedicated geometric shape.
The four basic elements are: fire, earth, air, water. 
Their respective shapes are: circle, square, triangle, and oval.

3D and 4D shapes will be added late in the story.

“Hey monster, you're not ready for this blow, but I don't give a shit!!” said Lian as he drew a giant circle in his mind.

Then, a few istant later, a fireball as big as a house hit a monster just over 4 meters tall... 
It was a waste of resources, but it was damn fun!

“BOOM!!!” he said as the fireball reached the monster, covering it entirely.

The excitement on his face was palpable as his clothes and hair fluttered from the power generated by the impact.

“Tsk, it's really hard to achieve 100% accuracy when casting spells... that just means I have to do better!”

Meanwhile, the monster and the entire area around him was destroyed. The crater was huge, flames burned the ground, and ash mixed with dust covered the air.

Facing monsters from the Gates had become routine. Studying magic was a pastime. After all, he had the System, he didn't need to study classical magic. Or maybe not...

Geometric Mage: First Spell, Circle

After devouring several dead worms in a single bite, the colossal creature let out a guttural roar that made the air tremble.

Its mouth was as wide as a cart, adorned with a vortex of jagged fangs. On either side, two curved pincers formed a menacing clamp. Unlike its lesser kin, its segmented body was covered in a grayish-black armor, not yellowish, gleaming faintly under the harsh desert sun as if forged from molten steel.

Lian, with his swollen face, stared at the monster almost with gratitude, while Seline's green eyes shimmered with fear, her hand pressed against her aching ribs.

"Here it is, the boss has finally arrived," the man said with a giant smile on his face. His gray eyes oozed confidence. "I was getting tired of killing those useless weak worms."

"Oh," he added, casting a sidelong glance at the two kids before turning back to the monster. "My name is Freddy, nice to meet you."
