Lynn's gaze swept over the ten one-ring magics, and after hesitating for a long time, he chose "Ice Touch" as the object of improvement.

The principle of this magic is also very simple, that is, to manipulate the water vapor in the air, to cool it down, condense to interfere with the enemy, and the role it plays in the battle is very limited, if it weren't for the fact that this thing also has an advanced magic [Ice Domain], I'm afraid there are not many people willing to learn.

Lynn has no intention of learning, but is ready to transform according to the principle of this magic, such as casting this magic with another element!

And the elements he chose were ...... Nitrogen!

This element is known as Thurus in the Wizarding Lands, and in Koru's manuscripts, it is even classified as useless......

Considering that nitrogen is an inert gas and generally does not react with other substances, it is normal for some wizards to ignore it directly.

However, Lynn knew that nitrogen was not as useless as the other party said, not only could it be used to make fertilizer, act as a protective gas, but also synthesize another toxic gas, ammonia, with hydrogen......

The most important thing is that the boiling point of nitrogen is minus 196°C, which is terrifyingly low 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 this protection formed by the vapor layer is very weak, and it will be disintegrated in just two seconds.

Then the fragile skin will face the extremely biting ultra-low temperature, the cells of the epidermis will quickly die and fall off, and then all the fat, muscle, and blood will coagulate instantly!

The second reason why Lynn chose nitrogen is that the nitrogen content in the atmosphere is extremely high, accounting for about 7-80%, which means that he does not need to consume mana to produce this element additionally, and can create a large range of ultra-low temperature fields.

"071, turn on overload mode......"

Lynn silently said in his heart, and then closed his eyes and sensed that in the vast sea of elements, there was no need to look for active nitrogen elements at all, because they were everywhere, and it was easier to control.

After about four or five seconds, the temperature around the body began to drop rapidly, and the nitrogen that was close to liquefaction appeared in the form of a white mist, spreading out in all directions.

Click~

A slight noise sounded in the room, but the tea on the table instantly condensed into ice crystals after the white mist drifted...... Not only that, but the surrounding tables, sofas, and various decorations are covered with a layer of hoarfrost......

The goblin, who flew in through the chimney and was about to clean up the dish, crashed headlong into the white mist, and then felt a biting chill, and his skin, bones, and blood seemed to freeze.

The frightened goblin had just opened its mouth and before it could let out a scream, it was directly frozen into an ice sculpture, and its body was suspended in the air with its hands and the table as contact points......

"It's so cold~" After about a minute, Lynn opened his eyes suddenly, shivered, and then directly lit the fireplace in the room with the fireball technique.

The sound of the system in my head also sounded.

[5% of energy consumed, 53.7% of remaining energy......]

"Do you consume so much?" Lynn frowned, although there was one less step of magic mimicry, but controlling so many elements at the same time did require a lot of computing power.

Maybe it's a good idea to lower the control range, or just target one direction like Ice Touch.

And the casting speed just now is also a little too slow.,This has to be changed in battle.,The enemy won't give himself a minute to cast the spell.,It seems that you have to strengthen practice on weekdays......

Lynn summed up the advantages and disadvantages of this new magic, looked at the room that looked like an ice crystal world, and couldn't help patting his forehead, and when he saw the goblin next to him who was stiff and like an ice sculpture, his face showed a little helpless.

It's not good when to come, but when he experiments with magic.

Lynn immediately got up and walked to the frozen goblin, ready to find out if the other party still has the possibility of survival, the living creatures frozen by ultra-low temperature, if it is not long, there may still be a trace of life after thawing.

However, as soon as he walked over, the elf's slender arm broke off and fell to the ground with a thud, shattering into ice slag......

Well, it's hopeless......

Lynn shook her head, and could only dispose of the poor goblin's corpse.

In the Wizarding Lands, there is no such thing as a monster right, and there is no shortage of precedents where unlucky goblins have run to the training grounds of students, or entered a laboratory and were accidentally killed.

The usual penalty is a fine......

After all, these magical creatures are all the property of the Academy!

"I'm not supposed to be experimenting here!" Lynn sighed and touched his money bag, he was not rich now, and it seemed that the alchemy workshop had to be established as soon as possible, otherwise he wouldn't even have a secret place to practice magic.

Money, money......

Lynn muttered a few words with emotion, changed out of the robe stained with a little liquid nitrogen, took his professor badge, and he was going out to find money!

……

In the evening, on the west side of the harbor of Iyeta, in a remote workshop.

Darren, a halfling, was bored fiddling with Lydia's gadget, a T-shaped flying toy made of hollow wood, which could fly directly by the force of the wind with a heavy twist in his hand.

But why can this thing fly, but a bigger craft cannot?

Just when Darren was puzzled, the wind chimes hanging at the door suddenly rang.

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

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

It was Lynn who walked through the door.

It was too conspicuous for him to wear the professional robes issued by Iyeta Academy, nor did he wear a medal, but Darren quickly recognized that it must be a wizard.

Because when he was in the square a few days ago, Lynn had appeared next to the great wizard Hellam, and had a good conversation with him.

Realizing that this was a big customer, Darren immediately got up from his chair, rubbed his hands excitedly, and asked respectfully and humbly, "This wizard, do you need anything?" ”

"There's a lot of fun stuff in the workshop, you can look at this fan, you don't need magic, you can spin it yourself. Also, this model of a steamship, put it in the water, and then pull this rope in the back, it can really move......"
