"Silly boy, don't look at it, come over here." Mrs. Jenny screamed, still sighing at the huge Chen Hao in this laboratory.

"Oh." Chen Hao answered, and then trotted to Lady Jenny.

Lady Jenny pointed to a bookshelf on her right, and said, "Count the seventh row from the bottom to the top of this shelf, and count the fourteenth book from left to right." ”

"Oh." Chen Hao didn't know what the old lady had in mind, but he still complied.

He walked over to the bookshelf that Lady Jenny pointed to, searched carefully, and without much difficulty found the book she was talking about, which was a book called "Introduction to the Junior Alchemist".

Chen Hao took the book, walked up to Mrs. Jenny, respectfully handed the book to Mrs. Jenny, and said, "Madam, this is the book you want." ”

Mrs. Jenny didn't take the book handed over by Chen Hao, but pointed to the other side with an expressionless face and said, "There is a test bench over there, you refine the potion on page 345 of this book for me, and the materials you need are placed in the small cloth bag in the lower right corner of the test bench." ”

Calling me in to refine medicine? Chen Hao was stunned for a moment, and after coming back to his senses, he turned to page 345 of the book according to what Mrs. Jenny said.

The book was opened, and Chen Hao only saw a recipe written on it: Endurance Elixir.

Endurance elixir? What is it.....

Chen Hao lowered his head and carefully studied the relevant instructions of this recipe.

The Stamina Elixir is a potion that increases 20 points of Constitution in 60 minutes, and this attribute of Constitution can increase HP and defense, and after taking this potion, it is equivalent to increasing 100 points of HP and 20 points of defense.

When Chen Hao read the instructions for this potion, his eyes immediately lit up.

That's a good thing!

In terms of the current game progress and player level, 100 HP and 20 defense may not be much for a knight professional player, but for the small crispy professions in this game, such as the mage and thief, it is simply a miracle medicine.

According to Chen Hao's understanding, the current level 13 thief players generally have a blood volume of about 600~700, and there are very few players like Chen Hao who are equipped with the best equipment.

Chen Hao believes that once this medicine is taken out and sold, there may be people who are willing to buy it at a high price.

That's a valuable recipe!

Then, Chen Hao looked at the success rate of each level of alchemists refining this potion marked under the formula: the success rate of alchemy master level is 80%, the success rate of senior alchemist is 50%, the success rate of intermediate alchemist is 30%, and the success rate of junior alchemist is 7%.

Damn, the success rate is less than 7%, which made Chen Hao immediately stunned.

The success rate is also too low, doing 100 times to succeed 7 times, just like you can only get 7 points out of 100 points in the exam.

However, if the success rate is too high, the selling price will be cheaper, Chen Hao changed his thinking like this, and the sense of loss in his heart disappeared.

By the way, with such a big book in hand, there should be more than one recipe like this, and it would be a pity not to look at other recipes at this time.

Chen Hao wanted to open another chapter of the book under the idea of stealing the formula, but when he turned to other pages, he found that it was all blank and there was not a word.

At this time, Chen Hao received a system prompt.

"Ding"

System prompt: You are not allowed to view other recipes without permission to read them.

Sure enough, without permission, other formula players are not allowed to look around, or someone who steals a book and comes out will not have mastered all kinds of mysterious recipes.

At this time, Mrs. Jenny's voice sounded from behind Chen Hao: "What are you doing here, why don't you go quickly?" ”。

"Oh." Chen Hao responded, holding a trot and running to the test bench not far away.

The size of this test bench is the same as the test bench outside, but Chen Hao found some differences in the production materials, the test benches outside are made of stone slabs, and the test benches here are made of wood, and Chen Hao smelled a faint aroma when he approached the test bench.

It seems that this test bench should be a valuable object, and alchemist is really a rich profession.

At this point, making potions is the main thing.

Chen Hao first opened the small cloth bag on the table, checked the raw materials inside, and then read the recipe written in the book a few times.

Ten minutes later, Chen Hao probably knew what to expect.

He poured out all the ingredients in the small cloth bag like he was making an intermediate red medicine, and then patiently combed through the raw materials.

Once all the materials were sorted out, he began to make them.

I saw Chen Hao's hands like magic, putting the original into the container one by one, he was very patient to control the amount of each dosage, and control the time invested in each material.

Although there is no stopwatch, Chen Hao can still do it exactly right, just like a machine.

At this time, Mrs. Jenny had already walked in front of him and watched Chen Hao's operation process with her back to her.

From Chen Hao combing the materials to actually starting refining later, her cloudy eyes showed a hint of curiosity.

When she saw Chen Hao fiddling with the materials on the table like a machine, the curiosity in Mrs. Jenny's eyes had turned into surprise.

"Bang~"

With a slight explosion, a pungent smoke came out of the magic cauldron, choking Chen Hao to tears.

"Ahem, ahem, ahem......"

The first time I made it, I failed, and sure enough, this stamina potion was not so easy to cultivate.

"Go on." Lady Jenny didn't care about Chen Hao's failure this time.

Chen Hao glanced at the expressionless Mrs. Jenny, sighed, and began to play with the materials on the table again.

……

"Bang~"

There was another slight explosion, and Chen Hao's second production failed again.

Chen Hao sighed, then looked at Lady Jenny.

"Go on." Lady Jenny is still those two words.

Chen Hao started a new round of production.

"Bang~"

"Continue"

"Bang~"

"Continue"

……..

When Chen Hao experienced the seventh failure, he finally succeeded in the eighth time.

"Ding"

System Prompt: You have crafted [Endurance Potion], Alchemy Proficiency +2.

Unexpectedly, the proficiency of practicing this [Endurance Elixir] Alchemy can actually increase by 2 points, and it seems that there will be additional bonuses after the success of the difficult potion.

Chen Hao looked at the green powder that emitted a faint glow from the magic cauldron, wiped the sweat from his head, and smiled happily at Lady Jenny.

Lady Jenny said two more words with a blank face: "Go on." ”

"Isn't it a success? Why do you want me to continue? Chen Hao was puzzled.

"Let you continue, and you will continue." Mrs. Jenny ignored Chen Hao's protest and let Chen Hao continue to produce.

Chen Hao muttered in his heart: Old aunt, dead pervert. The movement of his hands did not stop, and he continued to fiddle with the materials on the table.

"Bang~"

The ninth time failed again, and without waiting for Mrs. Jenny to say those two words, Chen Hao picked up the ingredients on the table again, and began to make them again without stopping with both hands.

"Bang~" failed.

"Bang~" failed again. Chen Hao didn't care and continued.

For the eleventh time, Chen Hao succeeded again.

With a blank face, he poured the finished potion into the bottle and began to make the next one.

Slowly, Chen Hao forgot about the existence of Lady Jenny, and single-mindedly fiddled with the medicinal materials on the table, only these medicinal materials in his eyes, and only the medicinal herbs in his heart.

In the next few productions, Chen Hao actually succeeded. But there was not a trace of joy on his face, and there was not a trace of stagnation in the movements of his hands.

With his constant attempts, the success rate of making endurance potions was maintained by him at about 50%, nearly half of the success rate.

An hour later, Chen Hao already had a pile of stamina potions in front of him, and the pile of mountain-like materials had also been used up by him.

He came back to his senses when he reached out to the place where he had put the ingredients and found it empty.

He looked at Mrs. Jenny, and at this time, a smile appeared on Mrs. Jenny's face, and said, "Boy, I have a task to hand over to you, I don't know if you dare to take it?" ”

Task? When Chen Hao heard Mrs. Jenny say this, his heart was suddenly overjoyed.

Hidden missions again!
