Along the way, Arthur's color was like constipation, and the bulging magic stretched the soul space into a balloon that was about to burst, squeezing from the depths of his soul, making Arthur have to be careful with every step.

Back at home, with no one around, Arthur hurried into the dark portal, not the first time he had entered it, but he believed it would be the last time he would cross it as an apprentice.

"Arthur, how are you feeling?" Dawus's voice was relaxed, as if he wasn't worried about anything.

Every wizard has to go through this experience, and the more geniuses and students who want to break through the difficulties, the greater the entrance examination for graduate school.

"It's very uncomfortable, the magic wants to start liquefiing uncontrollably, and it has to be reverse-decomposed all the time." Arthur was like fighting, battling the magic within himself.

However, this kind of combat is extraordinary, compared to ordinary magic apprentices who cross the threshold of mana concentration and liquefy mana, Arthur is completely fighting against the laws of nature.

The bulging balloon must continue to inflate, neither leaking nor allowing the magic gas to shrink in size, only by allowing the magic power to continue to expand, poking a gap in the soul space, and the road to the second space will naturally be opened.

It's dangerous, but it's worth it, the amount of mana stored is multiplied by two, of course, for ordinary wizards, these two spells will be two completely different meanings, negative mana controls witchcraft, and natural elements manipulate magic.

In a single item, the amount of magic power of a wizard may not be comparable to that of a mage of the same level, but if it comes to staying power and suddenness, a wizard is far superior to a mage.

This is why even Melissa, who has mastered some of the laws and achieved the legendary rank, is afraid of the red robe, winning the red robe that only has the magic power of the mage and the control of the great mage, it is not enough, but also needs to face another great mage-level wizard to 'besiege' together, which will be a big loss.

Arthur's magic is different, it is just a single negative energy element, in fact, it should be said, and for wizards, when opening up a second space, the purer the negative element, the more difficult it is to open up a second space.

The natural elements that have been rejected do not have enough weight to puncture the barrier of the soul space, and must be manipulated by the wizard himself 'manually' to force the opening of the second space passage to complete this step.

There is not a trace of impurities in Arthur's magic, which is rare, and it also means that the opening up of the second space is almost several times more difficult than others.

Not only did he have to pressurize, but he also had to decompress, and the two-line operation almost made Arthur's brain power reach the limit.

"Teacher, you think too highly of me, let me pass the idea of long live, rushing to the college entrance examination with a full score, the difficulty is too high!" When Arthur first heard this analysis of difficulty, his head almost shook like a drum.

After all, it doesn't sound reliable, what if the magic power doesn't break through the barrier and condenses directly, is it difficult for you to be a half-baked wizard who only has a soul space to store magic power?

Arthur had a lot of half-heartedness, and he really didn't want to add more, so after Da Wus explained it, he finally dispelled his concerns.

It doesn't matter if there is no breakthrough during the apprenticeship, if it is an ordinary wizard apprentice who can't break through, then there will inevitably be a choice, whether to use natural magic in the overworld, or continue to insist on the rare negative energy magic?

It doesn't seem to matter if you use negative energy magic, but after all, there are only a few magicians in the Overworld who can resonate with their own magic powers.

Insist on using negative energy magic, not only do you have to face the trouble of thinning mana and replenishing difficulties, but what is even more unfortunate is that once you encounter a big battle of the same level and the magic power is released, because of the scarcity of negative energy magic stones, you don't have the ability to recover quickly and play again.

But this is nothing to Arthur, there is a wizard tower space, Arthur can hide in it at any time and recover slowly, and the rich negative energy magic is afraid of the lack of a source of mana replenishment.

As long as it is equivalent to the level of the great magician breaking through the magician, the magic power will naturally enter a period of expansion again, and at that time, the quality and control of the liquid magic power can easily break through the soul space barrier and open up a second space.

"What measures the wizard class is knowledge, and it is the level of cognition of the laws of the entire world, so wizards are not graded at this stage, and the knowledge of a wizard who condenses magic may not be more than that of an ordinary wizard." Davus's explanation of the simple class structure of wizards is also very simple.

Well, even so, Arthur doesn't plan to really fail, wait until the wizard level sprints once, the situation in this life is different from the previous life, the pressure is even greater, Arthur must have strong strength earlier, and he can't move forward slowly.

In terms of mana control, Arthur is also outstanding, quickly decomposing mana, and constantly filling it, when he arrives at the wizard tower, the abundant negative energy mana surges.

He unhurriedly controlled the mana to rotate back and forth in both directions like a washing machine, absorbing the mana while generating enough centrifugal force to prevent the mana from condensing in the center.

At this time, he needs to wait for an opportunity, a time to truly reach the limit of his magic power.

Sitting quietly in place, Lilia on the side also looked at Arthur nervously, she felt that a storm was brewing around Arthur's body, as if there were two big hands, pulling the magic in the air back and forth.

Extremely strong control is difficult for Lilia, who is born to control part of the magic power, and she can't help Arthur on the side, so she can only act as a food server and a microphone, so that Arthur can not worry about the changes in the outside world and break through with peace of mind.

The wizard tower is very quiet, Aragorn has long been left in the overworld by Arthur, this big demon is now more and more dangerous, thinking of ways to intercept the magic power, and wants to leave himself the capital to upgrade again.

On weekdays, Riaser can still drain his mana by summoning a little greenskin, but he doesn't have this kung fu during the level, and any relaxation of mana control may cause a full transformation of mana.

Lilia sticks to Arthur on weekdays, but at the critical moment she is quiet like a rabbit, Arthur condenses magic and is also comforted in her heart, after breaking through the 50% mark, Lilia's temperament is getting more and more gentle, and the influence of the abyss is getting smaller and smaller, as long as she persists, she will definitely be able to defeat the abyss and become an independent negative elemental life, even like a half-goblin, becoming a powerful existence.
