Lu Sheng displayed his spellcasting talent early on in the next few casting tests.
He did not use Deep Blue, instead honestly laying his foundations on his own. While secretly searching for God-Entrusting Power in the Seven-Colored Dragons' treasure caves, he revealed only a small portion of his spellcasting talent, lest he draw too much attention from the elders.
Because he possessed incomparably powerful soul force, he successfully stepped into the realm of a Level 1 Mage in his first year of coming into contact with formal spellcasting textbooks.
He easily mastered three casting languages and sixteen spell release models.
One had to know that casting spells required weaving one's spiritual power into all manner of models, combining them with various strange materials, and building the spell model as though constructing a machine.
Only then could one pour in and draw upon elemental power to release the spell.
Different spells required different proportions of various elements, much like mixing chemical reagents. Once any problem arose, the resulting spell could very likely explode unexpectedly.
Thus, the basic spells recorded in Spellbook textbooks were the most perfected models, refined through the continual improvements and accumulated efforts of countless spellcasters over innumerable years.
Lu Sheng did not dare modify or create his own spells lightly, either.
Under normal circumstances, the success rate for creating a spell ranged from five in a thousand to one in a thousand. The instability of the elements made explosions extremely likely.
Therefore, Lu Sheng simply followed the Spellbook step by step, improving his meditation.
Yet even so, within five years, he successfully entered the realm of a Level 2 Mage. To the elders outside, however, he displayed only the standard of an ordinary Mage Apprentice.
It was then that he began noticing the mechanism of the Magic Net.
