In Ditas Town, Merlin instructed Xialiberi not to let anyone disturb him.
Afterward, Merlin began the final step of constructing a First-Level Spell in his room: using his mental power to simulate the Spell Model. The First-Level Spell "Guardian Monument," reconstructed by Matrix, was about as complex as the Spell Model for "Berserk Flame" had been.
Previously, Merlin's mental power had not reached the second level. His six Zero-Level Spells had already occupied most of it, so when he had constructed Berserk Flame, it had been extremely taxing, and the construction had ultimately failed.
If he had possessed only four Zero-Level Spells, he likely would have successfully constructed a First-Level Spell long ago. But every gain came with a loss. He had become a Six-Element Spellcaster, and if he could advance to become a First-level Spellcaster, his strength would greatly increase. His potential was also immense, far beyond that of ordinary Spellcasters.
When simulating Spell Models with mental power, Zero-Level Spells had not been particularly complex, so Merlin could simulate one in his Sea of Consciousness within two or three hours.
However, the Spell Models for both Berserk Flame and Guardian Monument were far more complex than those of Zero-Level Spells. Merlin's mental power was now slowly simulating the intricate Spell Model. In his mental perception, the Spell Model of Guardian Monument resembled a three-dimensional image, densely packed with fine lines everywhere. An ordinary person would feel dizzy and disoriented after one glance, let alone simulate it within their Sea of Consciousness.
If not for Matrix's assistance, Merlin would have had almost no chance of reconstructing such a complicated Spell Model. He understood his own circumstances well. His talent as a Spellcaster was poor, whether in mental power or in constructing Spell Models. Only with Matrix had he been able
