The cold winter wind is constantly blowing, and the air exudes an icy chill.

In a small square, Lei Lin was naked and naked, practicing cross swordsmanship.

Several muscles in the chest already have a shape, and although the lines are not very prominent, they are extremely smooth, giving people a lean feeling.

Progress, Pick, Thrust, Every style is perfect, as standard as a textbook example.

After Leylin finished training, Anna, who had been next to the venue, hurriedly stepped forward and handed over a white towel.

Ray Lin wiped his sweat as he pulled out his count.

"Leylin Farrell's 2nd Apprentice, Official Knight Power: 3.1 Agility: 3.3 Constitution: 3.2 Spirit: 4.7 Mana: 4.0 Status: Health"

"Chip, how did today's practice work?"

"Testing! The main body's life energy has been increased to the limit, and none of the values have been improved!" said the chip's emotionless voice.

"It's finally this day!" Lei Lin sighed: "It's not bad to have these attributes to grow, and then investing in it will outweigh the losses, and the future knight training can be stopped, after all, the next step is to train your own martial arts proficiency, and not let yourself be born." This kind of thing, with the chip, I can always keep it in the best condition!"

After the knight training in the early morning, Lei Lin rested a little, and after the state adjustment was completed, he threw himself into the tense reality again.

In the room, Leylin put a purple leaf into the beaker, added a spoonful of dark green juice, and lit the flame below.

Bright yellow flames licked the bottom of the beaker, and purple bubbles kept coming out.

"Chip! recorded, the 145th physical reality, alternative materials: Hough purple leaf, Nino root!"

"Recorded!" the voice of the chip came, and carefully recorded the various changes in the medicinal properties and properties of the real yàn.

During this period of time, Lei Lin has carried out hundreds of real deductions, and the simulation deduction made with chips has exceeded tens of thousands of times.

"This time! I have a strong premonition that this time I will succeed!"

Leylin muttered as he stared at the volatile green and purple gases.

It was a very whimsical idea to try to replace the main ingredient of a wizard's potion using materials used by ordinary people, and there were countless obstacles to it.

In addition, although most of the materials required for several realizations are materials that can be bought with gold coins, it also needs to add some auxiliary materials that can only be obtained by wizards.

Those were all purchased by Leylin at the Wizard's Bazaar, and they are almost consumed now.

If it weren't for the chips, a large number of simulated real products could be used, and Leilin's current consumables were still far from enough.

Just a few pre-emptive materials can make the current Lei Lin bankrupt.

Crash!

The purple leaves inside the beaker had completely dissolved, and the green juice suddenly became somewhat transparent.

"It's now!" Leylin's eyes widened, and he picked up a glass rod and put it into the beaker, and began to stir in the opposite direction, a trace of mental power carefully followed the glass rod into the beaker.

As time passed, Lei Lin's expression became more and more solemn, and even beads of sweat hung on it.

A soft sound came from the beaker, and many black spots appeared in the center of the pale green juice, like small insects, spreading around.

Thunderlin's face remained unchanged, and his palm was as swift as a phantom, and he threw the red pearl that was placed in a petri dish next to him.

As the pearl was thrown in, the black spots in the beaker quickly faded, and the pale green juice quickly faded, and finally completely turned transparent.

It is expected to replace 45.8% of the main material with 45.8% of the medicinal properties. ”

The prompt sound of the chip was extremely pleasant to hear to Leylin at this moment.

"Coupled with the simulation and conjecture of the chip, a total of tens of thousands of times of real yàn, finally succeeded!" Lei Lin smiled at the corner of his mouth and clenched his fist fiercely.

At the same time, Lei Lin also sighed deeply in his heart for the difficulty of improving the formula for pharmacists.

He still has the original formula, and there is a chip for him to simulate and calculate, saving a lot of time and materials, and it took so long to improve a formula, if it is replaced by his senior brother Merlin, I am afraid that he will not be able to bear the material consumption in the early stage, even if the family support behind him is not good!

After all, it is really not what a sane wizard should do to waste precious materials again and again, to gamble on a hope of less than 1 in 10,000.

Moreover, in the process of realization, the pain of failure will also torment the pharmacist day and night like a fire, and the one who can finally complete the improvement of the potion is either the lucky one who was born, or the potion master with extremely rich experience and skills!

However, if the formula improvement is successful, it often means a great gain, especially this elixir that can boost mental power.

"Chip, if you start formulating Azure Elixir with alternative materials, how much effect can you have from the original?"

"In the comparison, the data of the number jù library is insufficient, and the conjecture model is established...... The new version of the potion is estimated to be 35.4% effective in the original version!"

"The effect is a little lower!But there is no way, most of the alternative materials I use are the most ordinary goods, even civilians can get them, and the quality can be made up for by quantity!"

Lei Lin analyzed the pros and cons of the new Azure Elixir, "This recipe alone is estimated to be worth at least 100,000 magic stones! Unfortunately, this is a prescription specially matched by the chip according to the number of my body, and for other people, it is really difficult to estimate how much effect is left." Moreover, the preparation steps have become extremely complicated, and there are a few steps that you can't get through if you don't have a chip! Changing to other pharmacists is definitely a few failures!"

In fact, Lei Lin knew in his heart that even if he became an official wizard, if he was known by others, he would not be able to keep this secret recipe, after all, a new spiritual power potion recipe, and the materials could be collected in large quantities, which could already change the low-level power ratio of various academies and organizations, and no force would let it go.

After making up his mind and burying this recipe in his heart, and only using the potion for himself, Lei Lin sorted out the traces of the real yàn before leaving the door of the real yàn room.

"Young master!" Anna, who was a little sleepy in the chair on the side, quickly got up.

"Butler Walker came to you two hours ago, as if it was for the sake of the medicine store!"

"Really, let him come to my study after dinner!" Lei Lin took off the stain-removing robe specially prepared for Shi Yàn and changed into a loose and soft garment.

"What's going on lately besides Walker?"

Lei Lin casually came to a sofa and sat down, and on the table were purple grape-like fruits and a red berry, both of which were Lei Lin's favorite fruits.

"Knight Fresa came here once, saying that the bounty mission released by the young master last time has made progress!"

Although Lei Lin didn't think about the tasks assigned by the academy, he still had to do the superficial work, so he issued a bounty task, asking the mercenaries and adventurers of Polar Night City to investigate the situation in the Dark Night Forest for him, and he could get a bounty of up to 1,000 gold coins, and now it seems that he has also gained something.

After dinner, Leylin met with Walker Sr. and Freisa in his study.

Freisa was still as strong as ever in leather armor, while Old Walker looked even older, and his body was even more rickety.

Old Walker saluted to Lei Lin: "Dear young master, our medicine store's income this month is ......"

"No need to say more!" Raelin leaned back behind his desk and waved his hand to interrupt Old Walker's words: "Tell me to go down and give me all the money to buy the Purple Leaf of Hove, Nino Root, and the Three-Flower Snake Fruit......"

"Then may I ask the young master, how much are you going to buy?"

"All!"

"All?" Old Walker looked up and stared at Leylin in shock.

"That's right! all the three medicinal materials I mentioned above on the market, you have to buy them for me and store them in the manor!" Lei Lin didn't have a trace of expression on his face.

"But...... I have to remind the young master that due to the recent poor management of the medicine store, as well as some medicinal materials that the young master has to collect from time to time, our current medicine store accounts are already in a rather dangerous situation...... "If the manor hadn't been giving out gold coins in advance, I'm afraid it would have closed down long ago-this is what old Walker said in his heart, but he didn't dare to say it."

"I know, but you have to remember! The gold is not enough to apply directly to Anna, the acquisition cannot be stopped, this is an order!" Lei Lin crossed his fingers, although he was only about fifteen years old, he actually looked a little more powerful.

"Good...... Okay! I see!" a cold sweat appeared on Walker's forehead, and he bowed straight out.

Unlike Anna, he didn't know Lei Lin's identity, so he naturally had some doubts about Lei Lin's approach.

But for Lei Lin, the purpose of his formation of forces is to better serve himself, help him do chores, collect materials, and even if he loses a little gold for this, it is nothing.

A qiē is all for his progress on the wizard's path, and other than that, anything else is an obstacle!

"Although I embarked on the path of a wizard, it was just to get real freedom and get an unfettered life, but unfortunately, with my current strength, it is still far from enough!"

Lei Lin sighed in his heart, although now he seems to have obtained the status of a superior person in Polar Night City, and he also has a manor and a servant, but for wizards, these are just illusory soap bubbles, as long as they are poked lightly, they will be completely ruined!

The aftermath of the battle between any two official wizards would have brought the current Leylin to death!

What is the use of short-term comfort when life and death cannot be completely guaranteed?

"Not to mention, as long as the Black Bone Forest Academy is completely defeated, the Gothic Sage's Hutch may list all the instructors and students of the academy as wanted criminals, and I will have to abandon Yiqiē and flee!"

"In these chaotic times, only one's own strength is the guarantee of freedom!!
