In the evening, while the students were leaving school or returning to the dormitory, Professor Kevin of Plastic Surgery sneaked to the merged square table and studied the rules on the square plate.
Does each square have to double the number in the previous one?
Kevin touched his chin and pondered in his mind. Just as he was thinking, a familiar voice came from behind.
"Don't bother calculating. It's absolutely impossible to fill up all these squares!"
"Do you know how much savings I have, Professor Philip?" Kevin asked with a little dissatisfaction. Besides, he knew a lot of good friends. Anyway, the money was just used to fill in the boxes and he could take it back after filling them. At worst, he could borrow some more.
Could it be that these squares are really as rumored, that even if all the wealth of the entire Yieta port was put into them, they could not be filled?
Kevin scoffed at this statement. This rumor was simply too outrageous!
"Do you know how many copper coins it takes to fill in the last square of these seven rows and seven columns?" Philip said helplessly. "It's two hundred and eighty-one trillion!"
"Two million, eight hundred and one thousand copper coins, that's a lot..." Kevin was somewhat surprised, but after a pause, he suddenly realized that the unit Philip mentioned seemed to be... ten thousand... billion?
"Wait, are you sure you didn't make a mistake?" Kevin was completely confused.
It was the first time he heard of the unit of trillion.
"Of course not! I have verified it myself..." Philip said unhappily. He was also a little surprised when he heard the apprentices talk about it before, and then he used nine sheets of manuscript paper to finish the calculation because the numbers were too long.
Kevin silently did the mental arithmetic in his head. Although it was just the simplest multiplication, the numbers became larger and larger as he continued to calculate. It became difficult for him to sustain the calculation just by mental arithmetic, so he could only make a rough estimate.
Based on the experience of the previous columns, the amount will increase about tenfold every three to four grids.
There are a total of forty-nine grids, which means... at least one hundred trillion times!
Kevin couldn't help but gasp, this kind of growth was simply too terrifying!
Not to mention the Yieta Seaport, even if the entire continent was emptied it would be impossible to raise so much money!
Fortunately, he chose to try it secretly when there were not many people around, otherwise he would have made a fool of himself in front of the students.
Kevin secretly rejoiced in his heart, and then he found that in addition to the rows of squares on the square table in front of him, there were also some strange characters engraved on it.
When q≠1, Sn=a1(1-q^n)/(1-q)
"What are these runes? Some kind of magic symbols?" Kevin asked puzzled.
"This seems to be... the formula for summing a geometric series? That should be what it's called, right?" Philip said uncertainly. "Professor Lin En said that as long as he figures out the last number, he can figure out the total of the copper coins in these squares within ten seconds."
"Can such a large amount of data really be calculated within ten seconds?" Kevin frowned.
"Master Helaram seems to have figured out the meaning of this math formula!" Philip exclaimed, "It's only been an afternoon. You really deserve to be called the Great Wizard."
"Did the master tell you what these Olympiad symbols mean?" Kevin asked eagerly. After doing some exponential calculations, he found that this so-called Olympiad mathematics seemed quite interesting.
"No..." Philip shook his head regretfully. "Master Helaram only asked me to come here to add a small reward to this game. Whoever can first figure out the meaning of this formula will receive a reward of 20 magic gold coins!"
As he spoke, Philip took out the gold coins and used magic to fix them on the square table.
……
At this moment, the subject of everyone's conversation, Lin En, the new professor of Olympiad Mathematics, was sitting leisurely on the sofa in the room, eating the dinner brought by the goblins while checking the "Basic Principles of Magic" and "Analysis of Elemental Magic" borrowed from the academy library.
Although the life of a professor at Yieta College is very comfortable and he does not feel the slightest bit of crisis, Lynn will not slack off because of this.
Everything in the wizarding land was unfamiliar to him. Once he encountered any trouble, the only thing he could rely on was his own strength.
In addition, as a professor, he also needs to make up for some basic magic knowledge.
However, these two books on the principles of magic written by legendary wizards gave Lin En a headache, because the books were filled with a large number of words such as [Serlu], [Enzesi], [Koze], etc. that made him completely confused. He could only verify them bit by bit based on the descriptions of these nouns in the books.
It took more than three hours of analysis, combined with his slight understanding of magic after the time travel, Lin En could barely understand the first half of the book.
First of all, his previous guess was not wrong. Wizards did release magic by manipulating, influencing, and mimicking elements.
However, the abilities of formal wizards are very limited. They cannot control all elements, and their precision is not enough. At least, they cannot smash molecules or atoms. They can only perform simple arrangements and combinations.
"Hydrogen, oxygen, nitrogen, phosphorus..." Lin En silently thought about the four elements he had controlled, and couldn't help but have some guesses in his mind.
First, the difficulty of element manipulation may be related to the element period. For example, official wizards can only manipulate the short-term elements in the first three rows of the periodic table, but cannot manipulate the long-term elements in the fourth to seventh rows.
The second is determined by the number of nuclear charges in the element.
The third is to divide it by metal and non-metal elements.
Lin En had experimented with this before, trying to cast zero-ring magic [Elementary Matter Deconstruction] to disintegrate the steel sword in his hand.
The result was obvious that he failed!
No matter how hard Lin En tried, the sword remained motionless.
This means that a wizard apprentice or even a formal wizard cannot directly affect the metal element with his abilities.
Of course, this is not necessarily the case for great wizards and legendary wizards.
Because according to the "Basic Principles of Magic", [Basic Material Deconstruction] also has two advanced magics.
They are the fourth-ring magic [Advanced Material Deconstruction], and the seventh-ring magic [Great Disintegration]!
Coincidentally, the fourth ring and the seventh ring are the dividing line for promotion to great wizard and legendary wizard!
While thinking about it, Lin En asked 071 to record these contents in the research file, and then turned to the second half of "Basic Principles of Magic", which contained even more mysterious descriptions of magic power.
This legendary wizard regards magic as the origin of the entire universe, the most basic substance that constitutes all matter, and the true power of creation!
"The origin?" Lin En frowned. Based on his observations over the past few days, magic power seemed to exist in every corner of this world. However, unlike elements, he could only sense it but could not truly 'see' it. Unless he used magic such as [Magic Missile], the magic power could be materialized for a short period of time.
Forget it, this is obviously not something he can study clearly at his current level...
Lin En touched his head which was aching from thinking too much and decided to put this question aside for the time being. Then he opened "Detailed Explanation of Elemental Magic".
[Fireball], [Corrosion], [Loud Spell], [Touch of Ice], [Secondary - Hand of the Fire Demon], [Pyroblast], [Poison Field]...
The entire book "Analysis of Elemental Magic" records a total of seventeen types of magic from the first ring to the third ring.
Lin En glanced at the so-called second and third ring magics, and then stopped paying attention to them. Instead, he turned his attention to the first ring magics.
With the help of the intelligent brain, although he can complete magical mimicry as a wizard apprentice, which is something only formal wizards can do, he is only limited to learning and using first-level magic.
For example, the principle of the three-ring magic poison field is to use magic power to transform it into some kind of toxic gas, which could be chlorine or fluorine. In short, these are not elements that he can get in a short time.
If it cannot be analyzed, it cannot be converted and used. His mental power is far from enough to cover such a large area.
In close-range situations, it is better to simply lower or increase the oxygen content in the air, which can achieve a similar effect.
With his current abilities, learning and improving the first ring of magic would be the least troublesome thing to do.
And first-ring magic is also divided into ordinary and superior.
The so-called higher-level magic is actually a simplification of higher-level magic, or an enhancement of lower-level magic.
For example, his [White Phosphorus - Fireball], strictly speaking, belongs to the first-level upper magic, but due to the highly toxic and difficult-to-destroy nature of white phosphorus, its power reaches the level of second-level magic.
Another improved magic [White Phosphorus - Hand of the Fire Demon] has a destructive power close to that of a third-ring magic.
But Lin En was well aware of the limitations of white phosphorus.
Even though he used this thing to kill people everywhere in the Sekas Empire, he even killed Anluk, who was comparable to a three-ring wizard.
Lin En knew very well in his heart that this thing was fine for bullying those uneducated bishops, but its power would be greatly reduced if it was used against wizards.
After all, formal wizards can deal with the two important characteristics of white phosphorus. Once the information is leaked, it will not be easy to achieve good results.
Therefore, he must learn more magic to increase his trump cards...
Chapter 65: Ultra-low Temperature Field
Lin En's eyes swept over the ten first-ring magics, and after hesitating for a long time, he chose "Touch of Ice" as the object for improvement.
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 terrifyingly 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 period of 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 be faced with extremely low temperatures, the epidermal cells will quickly die and fall off, and then all the fat, muscles, 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%. That is to say, he does not need to consume magic power to produce this element extra to create a larger range of ultra-low temperature area.
"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.
Click~
A slight sound was heard in the room. It turned out that the tea on the table had condensed 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.
Living things that have been frozen at extremely low temperatures, if the time is not long, may still have a glimmer of life after thawing.
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...
