This is undoubtedly the dream of every three-ring wizard. There are thousands of official wizards in the entire wizarding land, but only a few dozen can truly become great wizards.

But the question is, how to do it? Just rely on the blood of the Eye of Death? "This is just our guess." Hank was a little more rational. If it was really that easy to get promoted, they wouldn't have wasted so many years as a three-ring wizard.

"No matter it's just a guess or not, I'm going to ask North clearly..." Barbara said excitedly. North, like them, had ordinary talent and would never hope to become a great wizard in his lifetime.

If the other party can be promoted by this method, then I can do it too! "Ask...how to ask?" Lin En said with a sneer.

Barbara's face suddenly turned pale. According to Hank, North was nowhere to be found now. He was probably hiding from them on purpose and carrying out some plan secretly.

What worried her even more was that by the time she found him, North might have already made a breakthrough, and then they would be at an absolute disadvantage.

"Maybe, we can find some helpers." Hank couldn't help but come up with a vicious plan in his mind. There are more than one or two three-ring wizards who want to be promoted to great wizards.

In a sense, they have plenty of allies!

Since North is so secretive, maybe he didn't use a proper method to get promoted. They can use this to threaten North to give them a copy of this method, otherwise they will let their confidants spread this matter to the entire wizarding land.

In order to find a possible way to get promoted, Hank and Barbara came up with many vicious schemes, some even a little crazy.

Lin En broke out in a cold sweat upon hearing this, and a hint of pity flashed in his eyes as he looked at the two of them.

Although Hank and Barbara were three-ring wizards, at this moment, they were almost no different from those apprentices who worked hard to become formal wizards...

But this is the cruelty of the wizarding world. Every level division represents power and power.

After discussing various ways to interrogate North and forming a temporary alliance, Hank and Barbara couldn't wait to say goodbye and leave.

They were all anxious to go back and study the bottle of blood they had obtained on the Sea of ​​Misty Mountains, so as to find out what was so special about it.

After the two men left, Lin En thought for a moment and took out a bottle of reagent containing dark green liquid.

During these few days, he naturally also did some research on the blood of the Eye of Death, but the results of the experiment were very bad. The power contained in this blood was very strange and had a strong rejection property, so it could not be used to brew the shaping potion at all.

Those rats that ingested the blood directly died inexplicably within a few seconds, and even an autopsy could not find any cause.

Lin En suddenly remembered that North once said that this kind of blood was used in some kind of alchemy array...

Perhaps we can start from this convenience.

…

While conducting research in secret, Lynn did not forget that he was still a teaching professor. In fact, his one-week vacation had ended.

During the period when the Olympiad classes were suspended, they were all studying the homework left by Lin En, which contained all kinds of strange questions.

For example, a wizard raised many chickens and rabbits in cages. Counting the heads, there were thirty-five heads in total and ninety-four feet in total. How many chickens and rabbits were there in the cages?

For example, another wizard spent ten silver coins to buy a camel, sold it for twelve silver coins, and then bought it back for fifteen silver coins, and sold it to another person for twenty silver coins. How much did he earn? In addition, there are snails running on trees for a while and resting for a while, frogs that want to jump out of the well but always slide down, carpenters who can't figure out how to match keys and locks, and finding the shadow area of ​​the intersection of two squares, etc.

Alok really couldn't understand what Professor Lynn's brain looked like and why he had so many strange questions.

Are those wizards from the Mystic Society crazy? Why do they have to keep chickens and rabbits in the same cage? They even have to count the heads and legs to determine the number. If they had the time, they would have separated the chickens and rabbits long ago.

"Very good, it seems that you all have mastered it well." Lin En took a general look at the homework.

Although there were many questions, they were all about the most basic knowledge of solving equations and geometry. It was just that the questions were presented in more different styles. They were all classic test questions that he had searched out in his intelligent brain.

It has to be said that the brains of these wizard apprentices are much more useful than those of ordinary people. Alok, Johnny and others are worthy of being students of the elite class. In just two months, they have already mastered some basic knowledge.

After hearing Lynn's words of praise, the apprentices couldn't help showing joy on their faces, especially Pierce.

As one of the apprentices with the longest enrollment time in Yieta Academy, the magic power in his body is already overflowing, but he has no talent in elements, alchemy, potions and plasticity, so he is forced to stay in the academy.

But the Olympiad Mathematics course was different. Although his talent was not as good as Elroc and Johnny, it was much better than others. This was his only hope for graduation! "Professor Lynn, have we completed this Olympiad Mathematics course?" Pierce asked excitedly.

“You’re still a long way from here. What you’re learning now are just the basics of the basics.” Lin En shook his head, not knowing whether to laugh or cry.

Is this still the basics?

Elroc, Peirce and others were a little bit unbelieving. They thought they had learned everything they could.

After all, they have now mastered various calculation methods such as addition, subtraction, multiplication, division, exponentiation, and square root. They can also accurately calculate the length, width, height and surface area of ​​various complex objects. They even know how many days it takes for a lazy snail to climb the wall and how many times a frog needs to jump to dig out a deep well. They can also calculate the strange situation of chickens and rabbits in the same cage clearly.

What else is there to learn from this?

"There are also trigonometric functions, probability, linear algebra, plane vectors, inequalities, infinite series, etc. Have you mastered them all?" Lin En asked with a smile.

Lin En's signature smile made the apprentices present shudder, and his words left them even more confused.

The only thing they know is the trigonometry... trigonometry! (End of this chapter)
