In a room inside the Wizard's Tower, Merlin sat cross-legged on the bed, with a fiery red potion in front of her, her expression solemn.

A third-level apprentice will attract the attention of his mentor, and he will also have enough energy to cast spells, and he will be able to do it easily when conducting alchemy experiments and puppet experiments...... The reason why she chose this time to attack the third-level apprentice was also because when she was chasing and killing Podos, her spiritual power broke through again, which gave her a greater certainty.

She didn't tell Serena and the others about the impact, she just said hello to her mentor Alonso, and for the others, Merlin just used the excuse of doing experiments, telling them not to look for her no matter what happened.

It's not that she can't trust Selina and the others, even if someone wants to harm her when she advances to the wizard tower, she can't do it, it's just habitual caution.

The third-level apprentice is the last realm before advancing to the official wizard. For wizarding apprentices who don't have special talents, this may be an unattainable goal in their lifetime, but for Merlin, it's not even a starting point.

The first-level apprentice only simply uses energy particles and cannot use spells, and his combat power is similar to that of a knight, while the second-level apprentice can already use simple zero-level spells, and his combat power far exceeds that of a regular knight.

As for the third-level apprentices, their spiritual power has far surpassed that of ordinary people, their understanding of spells is more profound, and they have mastered some spell-casting skills, and they can cast the prepared spells at an extremely fast speed, even the big knights are not their opponents. Moreover, the third-level apprentice is the reserve of the official wizard, and the sooner the third-class apprentice is promoted, the more likely he is to be promoted to the official wizard in the future.

For wizarding academies and other organizations, the number of official wizards is extremely rare, and Level 3 apprentices are the backbone of these organizations!

Any wizarding organization attaches great importance to third-level wizard apprentices, especially young apprentices...... Young, means strong plasticity, it is easier to succeed in the impact of formal wizards, and the major wizarding organizations have spared no effort in the cultivation of young third-level apprentices, so Mei Lin has to become a third-level apprentice as soon as possible.

"To impact a third-level apprentice, you need to master at least three spell models, and your mental power must also be able to cast eight zero-level spells in a row. ”

Mei Lin picked up the blazing red potion in front of her, this is the purification potion she purified, as for the spell model, she has already completed it, generally speaking, the fifth-level qualification is from a second-level apprentice to a third-level apprentice, it is difficult to do without a three-to-five year accumulation, but it took Merlin less than two years to complete the promotion from a first-level apprentice to a third-level apprentice...... Oh, no, it hasn't worked out yet, but she's confident she can do it.

After having Nebula, her mental power has been steadily improving, especially the condensation potion is like drinking water for her. Although drinking too much of the potion will leave a precipitate in her body, she already has a purifying potion that will remove all hidden dangers.

Merlin recalled the process of advancing to a third-level apprentice in her mind, and after making sure that nothing was missing, she drank the blazing red potion.

Call~

She opened her mouth and spewed out a fiery airflow, and it was as if there was a fire burning in her body, scorching every cell and bone, and even a person with a strong will like Merlin couldn't help but let out a soft moan...... On the surface of her skin, a layer of black and yellow oil oozed from the pores of her sweat, giving off a strange smell.

"It stinks!"

It took a full hour for the fiery heat to subside, but the grease was thicker, and the air was filled with a strange and unbearable smell, and Merlin had to rush into the bathroom next door.

"Whew, I'm finally alive, and I'm almost smoked to death. Merlin washed off the dirty grease and put on a new set of clothes, and suddenly felt refreshed, and even her body seemed to be much lighter.

"Now, it's time to start the formal meditation, to fuse the will runes, I hope this level can be easily passed. Merlin took a deep breath, sat cross-legged on the bed, and began to meditate.

Her consciousness soon entered the nebula...... In that brilliant nebula, twenty-four will runes were loaded and sunk, like twenty-four golden crystal runes, which looked very beautiful against the background of the nebula.

These will runes are spliced together by a lot of special structures, and the construction of each will rune requires a lot of time and energy, if there is an accident in the fusion process, the brain will collapse and die, and the rune will collapse and the level will fall, so Merlin must not fail. No one can guarantee that she will succeed, but Merlin is still somewhat sure - at least her will rune has always been nurtured in the nebula, protected by the nebula, and even if she doesn't succeed, she won't be harmed.

Under her meditation, the twenty-four will runes all bloomed with golden light, and even the surface of the nebula was covered with a layer of gold.

Rumble~

Under the influence of Merlin's will, twenty-four will runes began to merge, and Merlin only felt a strong force bombarding her mind, and she almost fainted.

"Suppress!" Merlin hurriedly relied on the traction of the nebula to suppress the fluctuations caused by the fusion of runes.

For the will runes she had constructed, Mei Lin's control power was not trivial, and after a few seconds, all twenty-four will runes stopped resisting and began to slowly merge.

Rumble!

The twenty-four will runes all came together and combined into an even greater symbol, and the spiritual power continued to increase upwards as if riding a rocket, and it took a while to calm down.

And on that huge rune, there are many mysterious lines, and Zhihai also feels even stronger...... Suddenly, a burst of golden light bloomed from the huge rune, and Mei Lin only felt a soft force that could not be refused to push her consciousness out of the sea of knowledge.

"My head hurts !!"

The sudden increase in mental power, with Mei Lin's current body, was also a little uncomfortable, and she felt as if her head had been beaten with a stick, and it took a long time to slowly calm down.

"Finally succeeded, the feeling of a third-level apprentice is really not comparable to that of a second-level apprentice. As long as you have Nebula in your hand, you can avoid damage to the greatest extent and increase your spiritual power and soul. Merlin breathed a sigh of relief.

The promotion of a formal wizard is far more difficult than the promotion of a third-level apprentice, so to speak, even if the difficulties of Lei Lin from an ordinary person to a third-level apprentice are added together, it may not be comparable to the difficulty of being promoted to a full-fledged wizard.
