The days go on, and venting won't solve the problem.

It took two weeks for Roshi to leave the forest, and by the time he approached the nearest city, he was finally relieved after many days of unhappiness.

When he came to the city, he was still the first to go to the Golden Rose.

The Golden Rose, which was originally the old Chamber of Commerce in the Northland Continent, has long since become the number one Chamber of Commerce in the mainland after decades of operation by Louis, and in addition to the hostile countries of the Prussian Kingdom, as long as it is in an area with city-state culture, it must establish its stronghold.

The materials required for the configuration of the spirit potion have been prepared, and Luo Xi asked for a mansion for Golden Rose, originally only planned to have a place to stay, and Luo Xi has never been very particular about what to live in.

Unexpectedly, Golden Rose simply allocated him a manor, a four-storey single-family main building, with a back hill for hunting, a garden full of golden tulips, and a pool in the center, the environment is generally full of luxury and elegance.

In this town of more than 100,000 people, there are no more than 5 manors of this size, and even a single ornament in it is enough for an ordinary person to spend a lifetime.

Roshi was not pretentious, so he simply cleaned up, emptied the clutter in the basement and converted it into a laboratory, and moved in the next day.

After that, the dispensing of psychotropic drugs began in earnest.

"Zziz!~"

The dimly lit basement was lit up by a burning kerosene lamp from Zizz, and a long wooden table was filled with test tubes, glass containers, and other instruments.

Preparing potions is not a wizard's specialty, and there are scholars who specialize in this field among mortals, and glass containers such as test tubes have been available for a long time, and Roshi can easily buy them in the market.

Low-level spiritual elixirs already belong to the classification of 2-ring elixirs, although only 1 main array and 6 sub-magic arrays are needed, but there are more than 100 magic circuits that need to be outlined in it, and there are as many as 287 characters that need to be used in total, and there are more than 60 kinds of materials needed.

In order to make it easy to configure and not make mistakes, Roshi prepared these utensils, labeled them one by one and placed them on the table, and crushed the materials needed into powder and assembled them.

After making preparations, Luo Xi took out the magic oil paper, then took out the stone and drank some meditation potion, and began to concentrate on the magic oil paper and slowly sketched it.

The mobilized magic power flowed with his mind to the stone pinched by his fingertips, and the gray stone gushed out some faint white light with the injection of magic power, and these white lights were the embodiment of Roxi's magic power.

When the stone touched the magic oil paper, it quickly left a black mark, spreading out like ink in all directions, but soon moved forward again under the direction of Roshi's brush.

The recipe for the spirit potion that he got from Geraint Roshi had read it many times, and he had the ability to memorize it in his heart, and he knew exactly how far he was going to go for each loop and loop, and he should outline it in that direction.

However, this does not mean that Roshi can easily complete the drawing of the magic array.

The pattern of the Memory Circle is only the first level in the drawing process, and the real difficulty lies in the magic power that is put into the Magic Circle when drawing.

Every loop, every rune, and even every point of drawing a magic circle needs to be injected with magic power at all times, and too much magic injected may lead to insufficient mana in the follow-up drawing, and if the number of injections is too small, there may be a breakpoint, causing the magic array to collapse.

Time passed bit by bit, and the quiet pins could be heard throughout the basement, except for the occasional rustle of stones as they cut through the magic oil paper.

The first time he drew Roshi, he didn't succeed because he didn't have a good grasp of the mana input when he was drawing, so he ran out of mana after less than half of the magic array was drawn.

He lowered the mana input again, but still didn't get a good result, and the mana injection was too scarce, resulting in a shortening of the loop not long after the drawing began.

Drawing a magic circle is not an easy thing to do, even if you let some experienced formal wizards draw it, you can't guarantee that it will succeed every time, not to mention that as an apprentice, Roshi has to face the problem of insufficient magic power.

After failing more than a dozen times in a row and wasting more than a dozen pieces of magic oil paper, Roshi did not choose to break through the difficulties in one go, but temporarily stopped and quit the laboratory.

After returning upstairs and letting the servants prepare a beautiful meal, after eating and drinking, Roshi went to the bathroom to take a hot shower and slept comfortably.

The next morning, he still didn't rush to start the experiment, but took out the big sword in the space ring, practiced in the courtyard for a while, and after the lunch break, he drank afternoon tea on the balcony and ate some pastries poured with honey.

Roshi has a habit of temporarily stopping to do something else and adjust his mentality when he encounters a more difficult problem that cannot be solved several times.

I don't know what the specific reason is, but whenever he comes to deal with this problem again, the dilemma that has plagued him in the past can always be solved quickly, and this time is no exception.

When he walked into the basement again, his mind seemed exceptionally clear, and he always had a hunch that this time it would be done.

The rustle of the stone touching the magic oil paper echoed in this laboratory again, this time the feeling did not disappoint Roshi, and the drawing was basically unimpeded all the way, and when the magic array was nearly a third of the way completed, he felt the drop in mana.

When the magic power in the body of a magic array was drawn and suddenly dropped sharply, the reality of the information fed back by the spiritual consciousness sea was not even one-third, but the magic array was only half completed.

Generally, this situation is caused by the uneven distribution of mana when drawing, and the first thing that most apprentices and even some wizards think of at this time must be to reduce the output of mana and speed up the frequency of drawing, and Roshi has taken the same measure several times before.

This time, however, he didn't do so, but continued to maintain the same magic injection and drawing frequency, as if he didn't hit the south wall and didn't look back.

The direct consequence of this was that when he completed another magic array, there was less than one percent of his magic power left, but a third of the magic array was still in the blank stage.

Seeing this situation, some apprentices have basically chosen to give up, after all, according to the previous rate, the only remaining bit of magic is obviously not enough, and it is just a waste of time to continue.

It's just that Luo Xi didn't seem to notice this gap at all, and still stubbornly continued to draw, but when he finished drawing the fourth magic array, he suddenly quickly adjusted his magic output, and the amount of magic output in each stroke was less than one-tenth of the previous one.

According to this amount, if it had been before, there would have been a breakpoint in the morning, causing the entire magic array to collapse, but the strange thing is that this time the stone still left a mark very intact.

The principle is actually quite simple.

Each circuit of this magic array, each character requires different mana, some require a large amount of mana injection, and some can be completed with just a little bit.

Luo Xi seems to be passing the time to empty his mind these days, but in fact, when he is practicing swords or drinking afternoon tea, his head will carefully recall every minute and every second of the previous drawings, and analyze the magic required for each rune.

It is with the collation of this information that Roshi has been able to maintain his mentality and move forward in an orderly manner when he encountered the problems he encountered in the previous few times.

As time went on, there was not much left of the kerosene lamp on the table that could burn for three days, and only a faint flame was left on it.

A layer of fine sweat also oozed from Luo Xi's forehead, and his face was even a little pale, and the large consumption of magic power even made him a little mental, and his head became groggy.

At this time, a large ring and six smaller rings had appeared on the magic oil paper, and the pattern of several runes combined by the magic circuit covered the entire magic oil paper, and the last ring was also close to the moment of closing.

It's just that Luo Xi's magic power is only a little bit left at this time, and if the current magic power is still injected, it is obviously impossible to complete this magic array.

Reduced mana output?

But...

He had never done this much in the first few draws, in other words, he had no idea what the last few magic circuits and runes needed to consume the minimum amount of mana.

What should I do?

Seem... Only...
