The principle of this magic is also very simple, which is to manipulate the elements in the air, cool them down and condense them to interfere with the enemy. Its role in battle is very limited. If it weren't for the advanced magic [Ice Field], I'm afraid not many people would be willing to learn it.

Lin En certainly had no plans to learn, but was preparing to modify the magic based on its principles, such as changing an element to cast the magic!

And the element he chose was... Nitrogen!

This element is called "Seru" in the wizard's land. In Kelu's manuscript, it is even classified as a useless element...

Considering that nitrogen generally does not react with other substances, it is normal that it is simply ignored by some wizards.

However, Lin En knew that nitrogen was not as useless as the other party said. It could not only be used to make fertilizers and act as a protective gas, but also be combined with hydrogen to synthesize another toxic gas, ammonia...

The most important thing is that the boiling point of nitrogen is minus 196 degrees Celsius. Such a horrible low temperature is enough to freeze most things in a very short time! Of course, due to the Leidenfrost effect, the human body can withstand high and low temperatures for a short time, but the protection formed by the vapor layer is very weak and will be disintegrated in just two seconds.

Then the fragile skin will face the extremely low temperature, the epidermal cells will quickly die and fall off, and then all the fat, muscle, and blood will solidify instantly! The second reason why Lin En chose nitrogen is that the nitrogen content in the atmosphere is extremely high, accounting for about 70% to 80%, which means that he does not need to consume magic power to create this element, and can create a larger range of ultra-low temperature areas.

"071, activate overload mode..."

Lin En recited silently in his heart, then closed his eyes and sensed it. In the vast sea of ​​elements, there was no need to look for the active nitrogen element, because it was everywhere and it was relatively easy to control.

After about four or five seconds, the temperature around the body began to drop rapidly, and the nearly liquefied nitrogen appeared in the form of white mist, spreading in all directions.

Crack~ A slight sound was heard in the room. It turned out that the tea on the table was frozen into ice crystals in an instant after the white mist drifted past... Not only that, the surrounding tables, sofas and various decorations were covered with a layer of white frost...

A gecko lying on the wall foraging for food was staring at a moth in front of it. Just as it was about to pounce, a white mist spread over it, accompanied by a biting chill. Its skin, bones and blood solidified instantly.

The gecko was still in the air, using its tail as a support point. The same thing happened to the moth, which was flapping its wings. Both of them remained in the same state at the moment of action, and were directly frozen into two ice sculptures.

"It's so cold~" About a minute later, Lin En suddenly opened his eyes, shivered uncontrollably, and then used fireball magic to ignite the fireplace in the room.

The system prompt sound in my mind also rang.

[Five percent of energy has been consumed, and the remaining energy is 53.7 percent...]

"Does it consume so much?" Lin En frowned. Although there was one less step of magical mimicry, the computing power required to control so many elements at the same time was indeed not small.

Perhaps reducing the control range, or targeting only one direction like [Touch of Ice] would be a good idea.

Also, the casting speed just now was a little too slow. If it were in a battle, the enemy would not give me a minute to cast a spell. It seems that I need to practice more often...

Lin En summarized the advantages and disadvantages of this new magic, looked at the room that looked like an ice crystal world, and couldn't help but slap his forehead. After seeing the gecko stuck to the wall with its body stiff like an ice sculpture, he walked over with some curiosity.

However, before Lin En took two steps, the gecko's long and thin tail broke directly because it could not support the weight of the body. The whole body fell to the ground with a snap and shattered into a pile of ice chips...

Well, it's beyond saving...

Lin En shook his head and started a fire to clear away the debris on the ground.

“I shouldn’t be doing experiments here!” Lin En looked at the house covered with frost and couldn’t help but sigh. It seemed that the alchemy workshop had to be built as soon as possible, otherwise he would not even have a secret place to practice magic.

If some reckless apprentice breaks in when I'm casting a spell next time, the consequences will be serious.

Money, money...

Lin En muttered a few words with emotion, changed out of his robe that was stained with liquid nitrogen, took his professor badge, and went out to find money! ...

In the evening, in a remote workshop on the west side of Yieta Harbor.

The half-orc Darren was fiddling with the gadget made by Lydia out of boredom - it was a T-shaped flying toy made of hollow wood. As long as he rotated it heavily in his hand, it would fly directly with the help of the wind.

But why can this thing fly, but larger aircraft can't? Just when Darren was puzzled, the wind chime hanging at the door suddenly rang.

"Welcome to the Half-Body Workshop..."

Darren quickly put down the toy in his hand and turned to look at the door.

It was Lynn who walked in.

To avoid being too conspicuous, he did not wear the professional robes issued by Iyeta College, nor did he wear any medals, but Darren still quickly recognized that he was definitely a great wizard.

Because a few days ago in the square, Lin En appeared next to the great wizard Hellram and had a pleasant conversation with him.

Realizing that this was a big customer, Darren immediately shuddered, stood up from his chair, rubbed his hands excitedly, and asked respectfully and humbly: "Mr. Wizard, is there anything you need?"

"There are many novel and interesting things in the workshop. You can take a look at this fan. It can rotate by itself without magic. Also, this steamship model. Put it in the water and pull the rope at the back. It can really move..."
