My blood regeneration is 100 million points faster

“Good choice.”

Kulov glanced at the oil bottle that Xia Zuo took out, nodded slightly and said:

"Foaming oil, when the friction heats up, it will cause large foams to form.

“But it’s so sensitive to temperature that the candlelight from the candlestick will cause it to bubble.

"And its foam is mostly air, with only a little bit of water, which will not significantly weaken the fire."

Xia Zuo realized that his mentor was guiding him.

He followed the two points put forward by the other party, and after thinking briefly, he put the foam oil agent back into the box and took out the other two bottles of oil agent.

The first bottle is heat insulating oil.

It can insulate temperatures below boiling water and is commonly used on the shells of teacups, water cups and the handles of soup spoons.

After applying and drying thoroughly, it will become a thin film that adheres closely to the surface of the object. It will not leave behind the smell of oil, nor will it melt due to contact with liquids such as water vapor and hand sweat.

The second bottle is a water-enriched oil.

There are many tiny particles wrapped in bubbles in this oil.

Under the action of external force, the bubbles will burst. When the particles in the bubbles come into contact with the liquid in the oil, a large amount of water vapor will be generated in a short period of time.

"There is nothing wrong with your idea. Now try to blend these two oils." Kulov pointed to the alchemy platform and said.

Xia Zuo touched the back of his head and said, "Professor, what if I make a mistake?"

Kulov chuckled, "If you make a mistake, you have to clean up the alchemy table. I won't fire you. This is not refining poison."

"That's good."

Xia Zuo responded with a shrug and a smile.

He walked into the storage room and found a grooved carrying frame. Following the instructions in "The Mixing of Oil Agents", he inserted the two bottles of oil waiting to be mixed into the grooves to prevent the bottles from tilting during transportation. , causing the oil inside to spill onto the ground.

Then he walked into the storage room again, and this time he took out a metal bucket.

Its lid is a piece of clear glass with a sealing ring.

There is a round hole in the center of the lid that also has a sealing ring. If you put the matching oil agitator here, you can safely mix the oil without the odor and oil leaking out.

Xia Zuo repeatedly confirmed that all the preparations were in place. He looked at his instructor and saw the other person nodded his chin. He put on his mask, removed the glass cover of the metal bucket, and inserted the anchor stirrer into the round hole.

The small bubbles in the water-rich oil are harder to pop than they look, but when blending the oil, you still have to stir it very gently.

Anchor mixers fit the bill perfectly.

Its paddles are close to the underside of the inner wall of the metal barrel and will drive the liquid to flow from outside to inside and from bottom to top.

Therefore, the oil that will come into direct contact with the blades must have very good stability.

Xia Zuo poured the most stable heat-insulating oil of the two oils into the bucket, then used a glass rod to guide the flow, and slowly poured in the water-rich oil.

Two completely different pungent smells wafted out of the barrel.

Resisting the urge to sneeze, he quickly and steadily replaced the glass lid and gently turned the handle of the blender.

The two-color liquid in the metal barrel gradually merged.

Whenever the paddle was about to cut through the bubbles of water-rich oil, he would turn the handle with gentler force.

five minutes later.

The two oils are completely blended together. The two-color liquid mixes to an amber color.

The next step is to use a soft bristle brush to apply the freshly mixed oil to the board.

or…

"Professor, can I soak the wood block in this barrel of oil?"

Xia Zuo walked to the table and leaned over to look at the pieces of wood. "You have to take them out to dry in the sun first so that the wood can dry out a little more. The effect of absorbing the oil may be better."

"The method you are talking about is called the infusion method. It is the entry-level content of oil alchemy."

Kulov pointed in the direction of the storage room and said, "We are now teaching at the trainee level, so we should use a brush to apply it."

"Okay, Professor."

Xia Zuo walked into the storage room and picked a brush made of short wool.

Wool brushes have the softest bristles and are especially suitable for contact with delicate things. Most makeup brushes are made of wool.

Xia Zuo spread a layer of oil-proof square cloth on the alchemy table, then placed a special stand for applying oil. He placed the two wooden boards on the stand and gently applied the oil with a wool brush.

After the front, back and sides of the wood block are painted, pick them up with iron tweezers and place them in the oven to dry.

Ten minutes later, Xia Zuo, who had been busy for more than half an hour, finally completed this practical training.

"Professor, do you want to test the fireproofing effect of these two pieces of wood?"

Xia Zuo said hesitantly... No matter what the test results are, the test equipment and venue will inevitably have to be cleaned.

"Of course. Find a deeper brazier."

"All right."

Xia Zuo measured the size of the wood with his arm and found the largest and deepest brazier in the storage room.

He placed the brazier on the stone tile floor of the alchemy room, used iron tongs to take red-hot coals and put them into it, and added a bundle of dry firewood.

After a while, a flame swayed in the brazier.

He picked up the two pieces of processed wood and put them into the brazier after a moment's hesitation.

"Zizzizi~"

The water vapor appeared much faster than expected. Almost as soon as the wood touched the flame, thick white water mist sprang out.

A sour smell filled the alchemy room.

Xia Zuo covered his eyes and nose and coughed a few times, "Ahem, Professor, is this considered a success?"

Kulov pulled off the rope loop at the corner, opened the shutters of the vent, and waved his arms to send the smelly white mist into the vent.

He walked to the brazier and took a look at the messy scene in the brazier:

"The solution to this application question is correct, but there are some problems with the proportion of oil. The fir wood itself has a lot of water, so you have to mix a separate oil with a smaller proportion of water-rich oil and oil for it.

"Generally speaking, if the full score is 100 points, you can probably get about 80 points."

Xia Zuo slapped his head, a look of regret appeared on his face. The instructor had mentioned the difference between the two types of wood at the beginning, but he had forgotten this detail.

Seeing the other party's appearance, Kulov chuckled a few times and said:

"Just pay more attention in the future. There are often some less obvious points in word questions. You can circle the key words in each sentence on the question, and then consider whether they are the key points in solving the problem."

"Yes, Professor. I remember."

Kulov looked at the wall clock on the wall and said, "There is still some time before dinner. Try making a bucket of mixed oil with a lower proportion of water-rich oil and oil."

…

5:50 p.m.

Xia Zuo tried blending the oil three times.

The score given by the instructor increased from 80 points to 98 points, saying that his temperament and proficiency in blending oils were good, but what he lacked was the experience in facing application questions.

To put it more bluntly, there are too few practical exercises in oil alchemy, so you need to spend more time training.

After the afternoon class, Xia Zuo spent another ten minutes cleaning the alchemy room.

Although the instructor can complete this work from a distance with just a few clicks of his fingers.

But he felt that it would be a bit embarrassing to always let his mentor do it for him. After all, he was his student.

By the time he walked out of the poison alchemy area and arrived at the castle hall, it was already past 5 o'clock in the evening.

A beautiful figure jumped over.

"You're finally out of class~"

Xia Zuo held the other party's little hand and said, "Next time, let's go have dinner first. You don't have to wait for me."

"No~ I want to wait for you to eat together."

Anruer crossed her arms and rubbed her shoulder, "I don't have classes tonight. After eating, let's go to the poison alchemy area."

Xia Zuo asked suspiciously:

"You should have finished your self-study of "Alchemical Linguistics," right? Why don't you have classes in the evening?"

"There are too many people in the oil alchemy subject. Professor Zhuo Lang not only has to teach the freshmen, but also teaches the seniors. Each of us freshmen can only attend 2 to 3 oil blending classes per week."

Anruer entangled her hair with her fingers, letting the ends of her hair tangle around her fingertips:

"Furthermore, my talent is not outstanding in the subject. I am not at the top, nor at the bottom. In the next two months, I was only scheduled to take three oil blending courses in the week before the exam. At other times, I was only 2 times."

It seems to be a bit rolled up... Sure enough, as long as there are more people participating in any place, competition and infighting are inevitable...

Halfway through the first semester after enrollment, the study atmosphere before the final exam will definitely become more and more anxious.

Xia Zuo led the slightly sad Anruer into the restaurant and found a table in the corner. He glanced around at the nearby classmates and did not see the fellows from Rossak Province - the miller's daughter Keli and the blacksmith's son. Little Mo Ben must have rushed to class, or was studying by himself in the library.

Senior Mars has recently been studying the alchemy of rare objects, striving to pass the promotion exam of this branch of alchemy as soon as possible. During this time, I rarely ran into him in the restaurant. Even if they met by chance, they would pass by in a hurry with a lunch box in their arms, say hello and run into the rare object alchemy area.

In comparison, Xia Zuo is the most relaxed.

There is only one reason why there are so few people in the Poison Alchemy Department.

The golden finger and the assistance of detection skills are the key to confidence in the final exam.

After the two sat down, they each ordered a simple meal.

Xia Zuo brought two drinks and handed the juice to Anruer, "Did you know that in the final exam, in addition to multiple-choice questions, there are also application questions?"

"Hmm, Keli mentioned it to me before lunch break today. Professor Zhuo Lang also mentioned it during class in the afternoon."

Anruer took the juice, took a sip and said happily:

"Fortunately, we were not assigned to the pharmacy and alchemy department. Whether it is Mrs. Morton's tonic and wound medicine branch or the functional pharmacy branch at the head of the college, the number of students is much more than that of the oil department. There are more than 30 alchemy tables. It’s totally not enough. Keli took me to complain for a long time.”

An alchemy platform covers an area of ​​about 10 square meters and is equipped with a stove, a crucible, a blower, two rows of shelves on the left and right, and a ventilation duct similar to a range hood.

The 30 alchemy platforms occupy at least 300 square meters. When these alchemy tables are turned on together, the scene of steaming mist is as lively as a cooking school class.

Xia Zuo couldn't help but worry about the quality of classes next semester.

In a few months, a group of new students will arrive at the school.

Their number is at least double the current number of students.

When the time comes, Anruer will inevitably have to queue up with them to use the alchemy platform...

When he thought that there was only one alchemy platform in the poison alchemy area... he felt his scalp numb. Wonder how Kurov would solve this problem…

The two of them waited for the dinner plates to be served, and immediately took the time to eat, rushing into the poison alchemy area before the evening class started.

Under the bright alchemical light, Kulov lay quietly on the soft sofa.

Xia Zuo walked lightly, pulled Anruer around the soft sofa, and said in a low voice:

"Professor is meditating, let's try to keep our voices as low as possible. The application question of poison alchemy is to make and identify compound toxins. Tonight I will teach you how to make black eye toxin, and you can identify it by referring to "Separation of Toxins"."

Anruer held the opponent's hand tightly and said anxiously:

"If I don't identify the black eye toxin, will I make Professor Kulov angry... Every time a student doesn't perform well in class, my instructor will jump in anger."

"It's okay, as long as you don't make any serious mistakes."

Xia Zuo paused to recall the refining process of Black Eyed Toxin.

Evaporating the water is a bit difficult.

When the poison evaporates into the air at an accelerated rate, the nose will become sour due to the pungent smell.

If the will attribute is weak, he may be unable to stop himself from sneezing, causing a pot of alchemical products to be scrapped.

Xia Zuo took a look at his attributes.

【Will】5

I looked at Anruer's will attribute again, and it was also 5 points.

An accident is unlikely.

However, her mistakes may be attributed to me... I have to be more careful. Otherwise, if something goes wrong, it will betray the tutor's good intentions and even lead to estrangement between teachers and students...

Xia Zuo thought for a few seconds and came up with an idea.

He came to the alchemy table, asked An Ru'er to stand half a meter behind him, and warned in a slightly serious tone:

"I'll refine it first as a demonstration. If you can't adapt to the refining process, then just identify the alchemical compound toxin. After all, this exam won't let us refine the compound toxin by ourselves."

"Yeah." An Ruer nodded her head and stood obediently where the other person was pointing.

Xia Zuo found two masks, put them on himself first, and then put them on for the other person. He carefully stuffed her hair into the hood so that the mask and the brim fit snugly without exposing any skin.

"When I cook it over low heat for a while, the liquid in the crucible will gradually evaporate. The smell is very unpleasant. If you can't hold on and want to sneeze, just push back a few steps and be sure not to touch me."

"Well!" Anruer held her hands nervously and stared at the other person's movements.

"Then I'll start. The first step is to add water and pour it to the crucible at the fifth mark."

Xia Zuo picked up the pottery pot filled with water and started to operate it, slightly slowing down the speed of adding the toxin so that Anruer could see it more clearly.

The first few steps are relatively simple, and it will not be a problem to explain them while you are doing them.

When the brown liquid was boiling over low heat, he only had time to turn his head and give a "careful" look, and then he threw himself into the stirring.

In this step, you must always keep an eye on the water and turn off the fire in time, and you must not blur the pot.

The vents above the alchemy table sucked away the poisonous brown mist, but a small part still spread to the surroundings.

Amidst the bubbling sounds, slight footsteps came from behind.

Anruer seemed to take a few steps back, then approached again without making any other movements.

Xia Zuo was convinced and continued to stir the crucible.

After about five minutes, the brown liquid in the pot turned into a thick substance.

He turned off the stove, turned the thick mass over with a spatula, stirred it like a fried egg, and used the residual heat at the bottom of the cauldron to evaporate the remaining water.
