PS: Thanks to glorybower for the monthly pass

Gehr was not surprised that Longbottom knew he was looking for Lorraine Crystal. The formula was given to him by Longbottom, and he naturally knew very well what materials were needed in it, and compared with the supply of materials on the academy's trading platform, it was easy to figure out the situation that Gehr was facing now.

"I see, I need to think again. Although Gehr had already made a decision, he didn't want to reply immediately.

"Well, then give me an answer as soon as possible, and if you decide, come to me, and I'll arrange for you and Luke to meet officially. ”

"Good ......"

Knock knock!

Just then, there was another knock on the door.

Gehr stood up, walked to the door, pulled away, and Serena appeared.

"Gehr...... Excuse me, didn't bother you, did you?"

After seeing Gehr, Serena wanted to say hello to him, but in a blink of an eye, she saw Longbottom sitting inside, and the smile on her face suddenly stiffened.

"Alright, when the matter is said and done, I'll go first. Longbottom stood up and walked towards the door.

"Okay. Gell got out of the way and let Longbottom out.

As he passed by the two at the door, Longbottom winked at the two of them and showed a ** smile.

In response, Gell looked calm, while Serena was a little embarrassed.

"Sit down, what's the matter?" After Longbottom's back disappeared into the hallway, Gell walked back into the house and motioned for Serena to come in.

"Well, there's something wrong with model optimization...... Serena glanced at the uncollected blending appliances on Gere's desk, and then withdrew her gaze. He closed the door with his backhand and walked over to the vacant chair. Sit down with your back straight. The posture is very dignified.

In the past few days, Serena has sometimes taken the initiative to come to the door to ask some questions about her knowledge, and by the way, she will help Gell clean up the room to show her gratitude. This is not a problem for Gehr, after all, he has only been here for a short time, he has not really integrated into this society dominated by wizards, and many of the ideas are still the same as when he was in Konatas, and it is not a problem for him to guide friends like Serena for free.

Of course. It's not the same as being a real wizard or apprentice, in their eyes the knowledge in their heads is a valuable commodity, and to gain their knowledge is to pay a price. Although Serena understood this, she knew that it would be too difficult to become a wizard if she studied like this alone, so she tried to come to Xiagel in the hope of getting his help.

But what she didn't expect was that Gehr was so easy to talk and taught her almost without reservation in her eyes. This made her very grateful, and she ran more diligently, and these days she will simply deliver food directly to every meal.

Gehr was happy to do the same, anyway in his opinion. Serena is not much different from Arwyn, whom he once taught at Motazaros, and it is both an investment and an experiment, and it will not have any adverse effect on him personally. Anyway, while he was teaching Serena, the soul module could continue to calculate other problems. It won't slow him down at all.

"Wait a minute, I have something to do. Gotta go out once. But Gell still has a lot to do, especially the testing of potions, and he can't wait to know what effect his work can achieve, so he doesn't have time to pay attention to Serena for the time being.

"It's okay, it's okay, you go get busy first, I'm just going to clean your room. Serena said quickly.

"Well, thank you then. Gehr stood up, went to the bedside, took out his backpack and a cloth bag, and carried it out of the room.

"No need to ......"

Before the word could be spoken, Gehr had already strode out of the room, and soon disappeared, only to see the last one flow gently from Serena's mouth.

Looking in the direction Ger had left, Serena bit her lip lightly, her eyes complicated.

......

"Summary of the effect, after taking the next standard dose, the skin keratin on the body surface will grow rapidly and mutate, forming a petrification layer around the whole body, with a weak and strong force field, equivalent to the defense of three standard knight heavy armor, for far and near physical attacks have a very good effect, although there is no direct resistance in the face of energy attacks, but the thick petrification layer on the surface will also have a certain effect, wait for thirty minutes after the effect has passed, the keratinous petrification layer on the body surface will automatically break and fall off, and there is no negative impact on the user's body.

Disadvantages: There is a gap of 10 seconds between the potion's consumption and its full effect, making it unsuitable for taking the potion in combat, and in addition, after the formation of the petrified stratum corneum, the overall weight will be twice as high as before the use of the potion, resulting in a significant decrease in the user's agility and speed, and the inability to actively remove the potion before the potion expires, so it must be carefully considered in the case of use.

......”

After consuming an entire tube of petrochemical reagents, Gehr finally obtained the most accurate data on the effect and had a clear understanding of the use of this agent.

This is a square room of about 20 square meters, whether the floor, walls or ceiling are all silver metal, under the illumination of several light sources on the wall, the whole room is bright.

The room is very simple, just a metal test bench and a desk, on which all kinds of equipment are very complete.

This is the dispensing laboratory that Gehr temporarily rented in the blending practice area, one of the many rooms in the academy's laboratory building, of course, the lowest kind, the high-grade one is not what he can afford now, the most expensive kind on the price list costs a standard spar a day, and now this most basic is much cheaper, and only two points in the identity card of Gehr Academy are used up in eight hours.

(Points are a small amount of money used in the academy, and 1 hedron can be exchanged for 100 points.) ）

On the desk in front of Gehr lay several small cages, which contained a white hamster with a large human head, a rabbit with fangs, a hedgehog that looked like a thorn on its body, and a monkey with a ghostly face. It was only from the rolling eyes and the somewhat alarmed screams that they knew they were still alive.

Gehr didn't bother with the test subjects. Instead, he picked up the used mixing utensils and walked to the side of the sink and opened the sink. Wash the reagent residue in the utensil with clean water and pour it into the pool.

After the utensils were disposed of, they were placed together, and Gehr sat aside and began to summarize some of the experiences of the previous experiments, waiting for the effects of the drugs on the test subjects to pass.

After about ten minutes, the subjects regained their mobility, and the cuticles on their bodies shattered and fell off, turning to gray powder.

Sweeping the powder clean, Gehr stopped caring about the little ones, picked up his own and opened the stone door of the laboratory. Walked out.

After settling the fees at the front desk of the laboratory building, Gehr walked out of the laboratory building.

At this time, it was almost late at night, and the sky was completely shrouded in black wings, leaving only the lonely moon still quietly showing its brilliance, only the insects were still making loud insect chirps, cheering for the moon's performance.

Looking ahead, there are no pedestrians on the road, only the lights that are constantly shaking in the breeze from time to time to guide the way ahead.

There are many apprentices in the academy, which is actually larger than a town compared to the colleges run by other organizations. The number of apprentices is only about 1,000, except for classrooms, libraries, or public trading platforms, where the apprentices are scattered, and it is difficult to see others at other times and places. Not to mention such a late night.

When Gehr returned to the dormitory building with his belongings, the entire dormitory building was eerily quiet, except for the sound of his footsteps echoing in the hallway.

Come to the door of your room. Gell opened the door, only to find that there was another person. As soon as I thought about it, I immediately judged that it was Serena. The girl hadn't even left.

The sound of Gell opening the door seemed to wake Serena as well, and a rustling sound rang out.

With a click, the door closed again, and Gehr had stepped into the lightless room.

Gell walked to the table, felt the oil lamp and lit it, just in time to see Serena sitting up from the bed, the curves of her body completely accentuated by the light close-fitting quilt, and the gray robe she was wearing was neatly stacked on the chair at the foot of the bed.

"I'm sorry, I'm tired of waiting for you, and I want to sleep for a while. Serena, who was a little sleepy-eyed, quickly apologized, and her face illuminated by the light seemed to be smeared with a layer of redness.

"It's fine. Gehr replied casually, and by the way, he prepared to put his bag and cloth bag back under the bed.

Just as Gell walked to the bedside, he keenly noticed a little strangeness on Serena's face: "What's wrong with you?"

"Nothing. Serena shook her head, then looked at Gell with a strange expression, "You...... You're a senior apprentice, aren't you?"

"Hmm. Gehr nodded. The standard for a high-level apprentice is to be able to build four magic models and manipulate magic items, and these standards have been met. "Why do you suddenly ask this?"

"I ...... I ......" Serena looked a little hesitant.

"What's wrong, do you need my help?" Seeing this, Gehr simply sat down on the chair next to the bed, looking at one of the first companions he had met since he came here, and wondered a little why she had become like this. If it's not troublesome, he doesn't mind helping her, after all, he has a good relationship with Serena and Buonie, especially when the other party first came into contact with him, he wasn't an orthodox wizard apprentice, so he didn't get along with the people he knew in the academy like the traditional apprentices who had a good relationship, but still had some coldness between them.

In response to Gehr's inquiry, Serena bit her lip, her eyes became determined, and she looked like she had made some kind of decision.

Poof!

Suddenly, there was a crisp sound, and Serena was already kneeling on the bed, her head buckled to the bed board.

"Gehr, for the sake of our past friendship, please accept me as an attendant!"

Although Gell couldn't see her expression because of Serena's kneeling position, from her tone, Gell could sense the indomitable determination in her tone. (To be continued......)
