The powerful monsters that have recently appeared inexplicably in the magic stone mine cave and the doomsday sect that suddenly appeared made Lynn smell a hint of danger.

The former is not something he can worry about, if those legendary wizards can't solve this problem together, and it won't help to add himself.

The latter is something that the current manager Ogst needs to consider, but Lynn will not completely rely on his own safety on others, so it has become an urgent matter to find a way to improve his own strength and deal with potential threats with ease.

Continuing to advance to the wizard level is undoubtedly the best choice, but he has only just been promoted to the second ring wizard, even if the huge power brought by the [Eye of Death] has not been completely exhausted, and the magic power is still in the stage of rapid growth, but there is still a distance from the next promotion.

Therefore, Lynn can only choose to start from other aspects, such as when he fought against Helram, with the blessing of the computing power of the nine three-ring wizards, he can even compete with a five-ring wizard for a short time!

Although Herram was overshadowed by him at that time, and was eaten by magic, the strength that could be exerted was only about three or four percent of the original, but it was also enough to crush the power of ordinary formal wizards!

It is precisely because of this that during the days she arrived at Greenriel, in addition to preparing materials for speeches and experiments, Lynn spent most of her time making the new [Arcane Ring].

As a distinction, these newly made rings are not as gorgeous as those given to Harrov, and they do not teleport the person they carry to [beyond time and space], but on a certain planet in the realm of magic, and the brain is frantically rushing to get the location of the second meeting as soon as possible.

In the end, Lynn set the number of people in the magic field at twelve this time!

The reason why he has to limit the number is that his brain has a limited capacity, and the more computing power he can mobilize, the better.

Second, the magic realm is in the stage where it has just been built, and it will be difficult to recruit too many people at once, in case of goofing.

As for the legendary wizard Haroff, who had entered the magic field before, Lynn didn't dare to let Zhi Brain try to crack the other party's mental frequency, after all, because the difference in strength between the two sides was too large, it was very likely that he would be perceived, and those three-ring wizards were his real targets.

At that time, with the [Deflection Force Field] as a protection and the [Space Vibration Wave] as an attack method, even if he faces a great wizard, he will never be unable to resist.

……

Two days later, at noon, in Greenriel City, a temporarily rented magic shop was already surrounded by water.

"Is this a glass mirror?" A young witch was surprised to pick up a round mirror the size of a palm, the smooth and flawless mirror perfectly reflected her beautiful face, white skin, red lips, and even the hair flowing on her forehead.

Almost instantly, the witch was captured, and after looking at it over and over, she was reluctant to put the mirror down, and in addition to being able to clearly reflect the face, the glass mirror itself looked like a work of art.

However, the high price made the young witch hesitate, and the more high-end and larger the glass mirror, the higher the price.

A life-size glass mirror costs as much as 20 magic gold coins!

Even for wizards, it's not a small amount!

"Beautiful witch, the number of this magical glass mirror is very limited, and the production process is extremely complicated, such as the largest life-size glass mirror, only the last piece is left, and the next batch of goods does not know when it will be made, if you miss today, you don't know how long you will have to wait......"

Darren, who was in charge of the sale, gushed endlessly, explaining the scarcity of glass mirrors to the witch in front of her, and repeatedly emphasized that the production of this thing was very low, and there were countless people rushing to buy it later, and if she came a minute late, there would be no mirror.

Seeing this scene, the young witch dared to hesitate, gritted her teeth, and immediately took out all her savings, a total of thirty magic gold coins, and bought the largest life-size mirror and a small round mirror that could be carried around.

Darren opened the drawer and stacked the magic gold coins he had just earned, and in just half an hour, the entire drawer was already full of glittering gold coins.

Lord Lynn's hunger marketing method is too good to be true!

In addition to the best-selling glass mirrors, they also made many equally beautiful glassware—teapots, teacups, and even trays—usually ranging from seventy silver coins to five magic gold coins, but compared to the extremely low cost of production, they were no different from grabbing money.

But this was not the case for the rest of the wizards, and this beautifully made glass was undoubtedly a symbol of status and status, so Greenriel soon set off a wave of buying glass.

There are also many shrewd wizards who want to buy them in bulk and resell them to other cities in the wizarding lands at a high price.

Also sold out, there are also two books, "Introduction to Olympiad Mathematics" and "Advanced Olympiad Mathematics", in addition to wizards who are curious about the thin and white pages, there are also many people who go to the Olympiad.

Tik is one of them, and when he listened to Lynn's lecture on the Olympiad in the harbor of Iyeta, he was deeply shocked by the subtlety and rigorous logic of this subject, and he was naturally very interested in the Olympiad.

So this time, when he learned that a master of arcane mathematics of the [Arcane Society] planned to invite twelve official wizards who were extremely talented in arithmetic to discuss a big problem in arcane mathematics together, Tik immediately became interested.

He was very confident that he could become one of the twelve, after all, compared to other wizards, he had listened to the Olympiad course for two months in advance, which had laid a solid foundation.

Thinking like this, Tik didn't even look at the so-called [Introduction to Olympiad], and directly opened the more high-end [Advanced Olympiad Mathematics], but after seeing the first question, the whole person paused.

[Find the exponential formula: 1^2+2^2+3^2+4^2...... 9999^2 and! 】

After repeatedly confirming that he had not misread the index symbol, Tik couldn't help but gasp, adding from the quadratic of 1 to the quadratic of 9999, and asking him to calculate the sum, which can be covered with dozens of manuscript papers just by writing down the complete formula, I am afraid that I will have to sleep tirelessly for ten days and half a month, and I may not be able to get the result!

That's just the first question!

Is it so hard?
