Catherine didn't learn these expertise, she was a wizard of the shadowy department, and seemed to be better at necromancy, spirit research, and corpse activation, and mutation and anatomy should be her best subjects, but when it came to this kind of study of the nature of magic energy, which required a lot of memorized formulas and a lot of calculations, Yenifa was better at it. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The two instruments had been put away by him, this thing was very expensive and squeamish, and after the measurement was completed, Yenifa carefully put it back in the container and put it up, for fear of bumping into it and scrapping the instrument.

In the empty corridor, the sound of "rustling" writing echoed constantly, and Yenifa held a quill and moved his wrist as if dancing, writing line after line of calculations on the sandpaper.

"That's it! I'll take a look at ...... coordinates I'm done" Yenifa looked at the ground - the floor of the corridor had been painted with paint to make it easier for him to calculate the coordinates, and then he began to search the ground according to the calculated coordinates.

After a short time, Yenifa stopped at the wall next to the end of the hallway, and according to the calculations, the coordinates should be further back.

"Is there a hidden room? It's a bit of a problem......" Yenifa scratched his head in annoyance.

"Wait! I have a solution!" said Catherine, who suddenly stood up.

Yenifa looked at Catherine with an expression of disbelief, a look of hell in broad daylight.

"What's your reaction, is there anything I can do to be weird?" Catherine puffed out her cheeks, looking puffed out.

"No...... It's just that I'm used to the way you've always been a fart, and I'm a little surprised when you suddenly say that you can crack the mechanism here. Yenifa waved his hand and said.

Catherine smiled smugly: "Although I can't compare to you in terms of decryption and calculation, I also have my own special solution to the current situation!"

Hearing Catherine say this, Yenifa couldn't help but be a little curious, and pricked up his ears to listen, he wanted to see if Catherine had any way to unlock the mechanism hidden in the official wizard's laboratory.

"Don't forget, I'm a dark magician, majoring in necromancy!" Catherine pointed proudly at the inside of the wall, "I can vaguely sense that there is a corpse in the hidden area of this wall, exuding a strong aura of death!"

"A corpse with a strong aura of death?" Yenifa was shocked, "That is probably the corpse of a wizard who is at least a high-level apprentice, and only when it reaches that level, the demonic energy in the body will last forever after death, and that strong death aura will be generated." ”

Could it be that the corpse belonged to the owner of this laboratory? Yenifa suddenly had such an idea in his mind, which made him excited, after all, the hidden area of the laboratory was almost impossible for anyone to enter except the owner himself, and the one who died there was probably the wizard himself.

"The magic steel alloy here has a powerful blocking effect, if my magic energy can find a way to enter that hidden room through this wall, I will try to activate that corpse and manipulate him to open the door for us from the inside!"

Catherine said.

Yenifa had a speechless look on his face: "Okay, although your method is theoretically feasible, but let me ask you, the condition for the success of your method is based on your sorcery being able to penetrate the magic steel alloy wall, but!

The reason why magic steel alloy was widely used by wizards to build important buildings is that it has a wide range of raw materials, low price, excellent strength, stiffness and toughness, fatigue and corrosion resistance, and at the same time has strong witchcraft resistance and magic energy barrier.

Of course, after all, there is still a big gap between the magic steel alloy and those real high-end materials, this alloy can resist the relatively weak first-level wizard magic energy at most, and the average first-level wizard can also cause damage to it, and some powerful first-level witchcraft can break it effortlessly.

However, Catherine, a junior apprentice, wants her witchcraft not to be blocked by the alloy wall, which is simply a dream.

With her little magic energy strength, she can't even make traces on the surface of the magic steel alloy, and she still wants to complete that kind of difficult, high-precision, and high-tech work?!

"Don't you claim to be invincible in 'Magic Mechanics' and 'Alchemy Materials'! You can't even solve a low-end material like magic steel alloy?!" However, before Yenifa could say the sarcastic words, Catherine said to Yenifa with a questioning look.

"Blame me?!" Yenifa spread his hands in a helpless expression, "If you want to make the magic steel alloy fail?, it's simple, as long as the temperature is higher than the 2000 standard temperature, or it is hit by a strength of more than 45 degrees." ”

The measurement of temperature in the wizarding world is very similar to Celsius on Earth, and wizards divide the temperature of water from the freezing point to the boiling point in a standard environment into fifty equal parts, one of which is a standard temperature, and 2000 standard temperatures are almost equivalent to 4000 degrees Celsius on Earth.

"So you can't help it?" Catherine couldn't help but hang her head a little, "I thought you were a study maniac who had a way to deal with the magic steel alloy...... Ahhh

"Although it is said to be a low-end alloy, it is compared with other materials, but in terms of metal properties alone, magic steel alloy is much stronger than those so-called steel and the like in the secular world. As he spoke, a flash of inspiration flashed in his mind, "Wait a minute, speaking of magic steel alloy, there is really a way to make it temporarily invalid......"

"Why didn't you say it earlier?" said Catherine, leaning over at once.

"I just remembered it, a theoretical point of view that was eliminated a long time ago, let me think about ......it," Yenifah held his chin and scratched his head and recalled with difficulty, "I don't remember the specific theoretical basis and arguments, including the data or anything, I only remember that the article said that the reason why the magic steel alloy has a lot of magic resistance is because it is mixed with demonic materials." “

"I don't remember exactly which demon-averse materials are, but I remember that there are diorite and black corundum and other components, because of these ingredients, so this alloy has a certain resistance to magic energy, but! These demon-averse ingredients have a low temperature fatigue life, and the method I saw started from this aspect. ”

Of course, in terms of the nature of the magic steel alloy, it will not hurt to do it once, but if the process of low-temperature freezing and then high-temperature heating is repeated many times, those demon-averse ingredients will fatigue and fail due to repeated extreme temperature differences, so that the resistance of the alloy to magic energy will be greatly reduced. ”

Yenifa recounted in detail all the knowledge she could recall, and although Catherine did not understand the whole set of theories of "metal fatigue", she still understood exactly what to do.

"Anyway, you just need to freeze at a low temperature first, burn it with fire, and repeat it many times!" Catherine patted her chest and said, "Leave the freezing to me, I still have some knowledge of witchcraft in the water cold system, and the water cold system is my secondary magic energy phase." ”

"Then I'll take care of the flame, and hopefully my flame will be hot enough...... If the temperature difference does not meet the criteria for making it fatigue fail, it will be a wasted effort. Ye Nifa said, the essence flashed in his eyes, and the momentum of the whole person became vigorous, and he had already entered the state of opening the first-order gene lock.

Since the second-order gene lock was opened, the first-order gene lock no longer has sequelae, and the first-order gene lock can also maintain self-awareness when the first-order gene lock is opened, and Yenifa can now use this as his usual skill.

Catherine also asked for the Frost Wraith's Ice Crystal Powder and the Frost Wraith Essence, and with the help of the cold of these two things, she was able to release the lower temperature of the frozen air.

A burst of cold freezing gas spurted towards this magic steel alloy wall, and fine and dense frost instantly formed on the wall, but those frost-like fine crystals immediately slipped down as soon as they formed on the surface, which was the magic energy resistance of the magic steel alloy at work, repelling the ice energy.

Catherine has been releasing freezing gas against the alloy wall, until the temperature of the wall has dropped to an extremely low level, if an ordinary person touches it with his hands at this moment, the entire palm will be frozen to death in an instant, and the low temperature on the alloy affects the surrounding air, and in the air within a radius of several meters, the moisture continues to condense, forming a small range of "snowfall".

"Alright, it's my turn. Yenifa motioned for Catherine to stop freezing, and walked over herself, and a huge fireball appeared in her hand.

Yenifa didn't directly throw the fireball out to blow up the wall, although the explosion is a way to release energy instantly, although the destructive power is large, but the temperature is not concentrated enough and not durable enough, so he chose to directly imprint the fireball on the wall, so that the fireball will burn the wall for a long time.

In this way, Yenifa used fireballs to heat the walls to high temperatures, and Catherine used freezing air to quickly cool the walls to low temperatures, and so on, and so on, and the last one lasted for about a little more than a standard hour, and the two had already rotated dozens of times, and they were all too tired to do so.

"I know why this method you said was eliminated...... "Catherine sat down on the ground very unladylike because she was really tired, "your method is too time-consuming and laborious, what can't you do with this effort......

"But at least this method is really useful! For us who are still shallow, this method is a little tiring, but it can allow us to deal with the magic steel alloy, and this is enough. Yenifa said, gesturing to the wall.

Catherine looked in the direction of Yenif's finger, and the walls were covered with frost.

Originally, these frosts could not be attached at all because of the rejection of the magic steel alloy, but now they are covered with a layer, which shows that the disgusting ingredients in the magic steel alloy have been completely fatigued and invalid!
