After solving the problem of acid volatilization, the problem of hemophilic acid bugs, and all kinds of possible problems, Leo believes that he and his "companion" will have little problem surviving in the mines.

But it's not so easy to get out of here. Because the title clearly states that teleportation magic cannot be used in the mine, it is completely closed, which means that you can only leave from the inside out. In this case, it seems that there is only one way left, dig a passage out.

But this approach seems obviously too stupid, it is not efficient, and it is not necessarily going to succeed.

Magic such as "fossil to clay" can only soften ordinary quartz stone, and once the stone contains a certain amount of metal, the effect of the magic becomes quite unsatisfactory.

In this case, if you want to rely on this magic, I am afraid that you will not be able to succeed at all without casting the spell hundreds or thousands of times, and this will also consume a lot of time and energy.

It's not difficult to make water in a mine, but food is a serious problem, so do you have to eat bloodthirsty acid worms to get by?

Fortunately, after remembering the content of the paper "Fluid Metals and Magical Structures", Leo finally had a relatively perfect solution.

About one-third of all known spells require the use of casting materials.

Since the casting materials are mostly scarce, difficult to collect, and difficult to carry, most mages do not like this type of magic. Naturally, Leo is the same, and the magic he currently has basically no magic that requires the use of spellcasting materials. But all mages have to admit that although they hate spell casting materials, this kind of magic has an irreplaceable role.

For example, when it comes to magic that changes in metal, magic materials are basically used. Because the properties of metals are often very stable in nature, it is difficult to achieve the desired effect without the addition of materials for catalysis.

In the paper "Fluid Metals and Magical Structures". The author elaborates on how to fluidize the metal that acts as the casting material when building a magic model.

In this way, the properties of the metal become extremely active. The magic catalyzed by this is naturally more powerful, and the functions that can be achieved are more complex and diverse.

This process is not easy for ordinary mages, as it requires subtle mental control. and channel the free magic of space to bombard in a way that fits the metal. Moreover, the action must be very fast and completed in a very short time, otherwise the fluctuations in the properties of the metal will decrease quickly after reaching a peak.

The author refers to this situation as the Weakening Period of Nature Fluctuations, the better the magic channeling of the metal, the longer the weakening period, and the time left for the mage to perform the magic bombardment will increase, and the success rate will naturally be higher.

Once the Mage successfully completes the bombardment at the peak of the metal's fluctuations, the metal will enter the fluidization process. Greatly increases the success rate of spell casting and magic effects.

Leo is not an ordinary mage, his biggest advantage is the strong control of his own mental power, if he wants to complete the fluidization of metal, I believe that he only needs to conduct a simple experiment to analyze the properties of the target metal, and then try a few times to succeed.

Of course, he didn't want to do this to cast spells, but to take advantage of the metal's properties. Complete the penetration of the mine.

The fluidization of a metal is a chain process, once a certain part of the metal is fluidized. The metals of the same type connected to it will also be fluidized under the influence of active properties.

Therefore, Leo believes that as long as he succeeds in fluidizing the blackened copper with excellent demonic guiding performance, then the blackened copper around it will be fluidized. And at this time, it is only necessary to find the place with the most blackened copper. Let all the blackened copper flow out, it is not difficult to get a relatively weak pure rock channel.

At this time, together with the "companions", it is believed that it is easy to open a passage to the outside world.

After sorting out the language, Leo was satisfied and wrote his answers on the test paper.

He moved his stiff neck. I was about to move on to the next question, but I happened to see Sanders blushing. However, this kind of red does not seem to be suffocated because of not being able to play the question, but rather like a surge of blood and qi caused by excitement.

It is not difficult to guess that Sanders must have had a similar experience to himself just now, not only completely immersed in the topic, but also feeling very happy and proud because he found a good solution.

This discovery made Leo feel even more that Geralson's ability was indeed extraordinary, and if he completed his studies according to the plan he gave, the speed of improvement would be far greater than before.

An hour later, Leo had successfully completed the test papers, as did Saunders.

As if setting an alarm clock, Geralson walked out of the break room on time to go through the two of them's test papers.

Leo was confident in his answers, so he acted fairly normal. However, Sanders is different, although he has also completed the test paper, but due to the environmental impact of his life since he was a child and has not been favored, he does not have much confidence, and he seems quite apprehensive for a while.

Geralson looked very carefully, and the absolute silence in the laboratory lasted for twenty minutes before he finished reading the two exam papers, and said with a blank face: "Not bad." ”

A simple and faint word, but Sanders's heart finally fell back from his throat. Although it is not "very good", it is not "excellent", but a "good" is enough to prove that your answer is recognized.

And Leo, who knows Geralsson better, knows how difficult it is to be able to say some compliments from the other party. It can be seen that the answers of himself and Sanders have indeed met the requirements.

Geralson didn't mean to comment on the two papers at all, and directly continued: "Let's start the next stage." Sanders, if you're going to get involved, you're going to have to do what I ask. I'm going to drain every bit of your energy out of the process, and the consequences of quitting are so serious that you have to think about it before you make a decision. ”

Sanders didn't expect the other party to allow him to join, his fat face was full of surprise, and then he responded without hesitation: "Yes, Professor!

Geralsson nodded in satisfaction and looked at Lorsath, "Since you don't want to participate in the tournament." Then stay here and be a helper. I just don't need someone to go to the material library to pick up something. ”

"Uh......" Lothas suddenly regretted coming here, but under Geralson's frightened gaze, he could only nod: "Okay...... Teacher ......"

Geralson pulled out a list, handed it over, and said, "Go ahead, get all these things back." I've arranged that the library should be ready, and when I get there, I'll give this list to Lucari. Remember to take a good inventory, I don't want anything missing. ”

Looking at the list that seemed to have no end, Lothas smiled wryly and turned to leave.

Geralson looked at the other two and continued, "As for what you have to do, it is to turn it into reality according to what you have just written in the test paper. Start preparing now. When Lorshas returns, start immediately. You only have this one day, and there will be new content tomorrow. So, you have to finish it today, understand?"

This time, not to mention Sanders, even Leo didn't expect Geralson to come up with such an idea.

However, he was very much in favor of the idea. First, through your own thinking and knowledge accumulation, find out the most suitable method. And then turning it into reality, the process is really a very emotional experience.

Sanders thought of these things as well. And I'm looking forward to seeing what I can do.

Little did he know, however, a real nightmare had just begun.

Because ideas are always good, but when you start to implement them, they are often not so satisfactory. What's more, the ideas in the test papers are basically extensive and ideal. There is many, many more work to make it happen.

The analysis of data, the combination of materials, and all sorts of unexpected little problems are enough to break a person's initial passion and confidence.

When the first problem faced its tenth failure, Sanders felt like he was on the verge of collapse.

And with Leo's encouragement and Lothas's rebuke. He could only hold on desperately.

In this way, it was not until two o'clock in the evening that he finally completed all the projects. And after that, the little fat man collapsed directly to the ground, and after only half a minute, he let out a loud snoring sound.

The next day, just after the sun rose, Sanders was woken up by Geralson.

This time, he gave each of them a set of test questions and asked them to implement them after solving them.

As a result, the miserable two had to stay up late to complete it.

The same was true on the third day, the fourth day, and all the way up to the ninth day, and it continued to increase in intensity.

In the blink of an eye, ten days have passed, and the little fat man has to maintain a high degree of mental concentration and high-intensity energy consumption every day. As a direct result, his weight plummeted.

Leo has no doubt that if this continues, the little fat man's weight will soon return to the level of a normal person.

Geralson "humanely" allowed the two to rest for a day, and then a new round of torture began.

However, it is no longer the previous model, but has directly become a proposition project.

The two need to complete his request by all possible means after Geralson gives his proposition. And the proposition from Geralson cannot be simple, of course, on the contrary, its difficulty and depth are far beyond imagination.

Leo and Saunders had to keep trying, but they also had to keep learning so that they could do it.

The terrible days went on forever.

Early in the morning, Leo and Sanders were so busy in front of the laboratory table that they didn't notice that the door to the laboratory was opened.

Lothas coughed, trying to get the attention of the two, but unexpectedly failed without suspense.

In desperation, Lothas had no choice but to speak: "Stop! I have something to say!"

"Don't make a fuss! we're busy! You can play by yourself for a while!" Sanders said without looking back, still fiddling with his magic array components in his hands. Experiencing several failures early in the morning made him feel a little uncomfortable.

Lorsaston choked back, and almost didn't catch his breath, but it took a while to calm down and say, "You two won't forget what day it is?"

"What day?" said Leo, looking up from the pile of jars. At this moment, he can be said to be unkempt, with the smell of various potions all over his body, and he can't see his handsome appearance at all, only his eyes are still shining, even deeper than before.

Lothas sighed and raised her voice, "The House Trials! Today is the day of the House Trials! All contestants must arrive at the Academy Central Square at eight o'clock, otherwise they will be considered as abstentions!"

"Tryout!" Sanders reacted.

Isn't everything I've done these days, all the pain I've endured, just for the tryouts? If I really miss it, I'll really regret it for the rest of my life.

His eyes subconsciously looked at the magic hourglass, and suddenly exclaimed: "Magic is on it! Why didn't you come earlier, it's only been twenty minutes!"

Lothas replied angrily, "How did I know that you two would even forget about this kind of thing! Fortunately, I went to the central square ahead of time, otherwise you two would be unlucky!"

"Alright, don't talk about that, let's hurry over!" Leo was also a little anxious.

At this time, the wooden door of the lounge opened, and Geralson walked out of it and said, "What's the hurry, enough time, go and clean up yourselves, do you want to use your current image to participate in the tryouts?"

Leo and Sanders were in no mood to clean themselves up now, but since Geralson had already said so, they couldn't disobey, so they hurried to the sink and quickly washed their faces.

Feeling the cool water flowing down his cheeks, Leo's originally impatient mood suddenly calmed down a lot.

Sanders did the same, looking at his much thinner face in the mirror, he felt that he was not the same as before, and an unparalleled confidence rose in his heart.

After this hellish study, all his inferiority complex has completely disappeared in countless failures, and all that remains is incomparable firmness and anticipation for the future!

Even if you have survived such a difficult thing yourself, then what problems cannot be solved?

No, absolutely not!

What the two didn't expect was that Geralson's voice rang out again: "When are you going to wash? Hurry up to the central square! I don't want to see you disqualified for being late!"

"What a weirdo, attitudes change too quickly...... "Sanders muttered inwardly as Leo and Lorsas left the lab and headed toward the central plaza of the Academy. (To be continued......)
