Alum, Silver Leaf Grass, and Swift Grass are all low-level alchemy materials, and it is not very difficult to find them, and there are already hoards in the castle.

Soon, Avrilan found some for him, and in addition, Rollin also managed to find several alchemical equipment, test tubes, flasks, and alcohol lamps.

The silver leaf grass swift grass was separated and put into the test tube and flask, and after several extraction and diversion developments, a few prompts soon popped up in front of Luo Lin's eyes:

[You made a brute force potion and gained 1 alchemy experience]

[You made a brute force potion and gained 1 alchemy experience]

[You made a brute force potion and gained 1 alchemy experience]

After refining the three bottles of brute force elixir, Luo Lin poured into the empty bottles that had been prepared long ago and prepared to cool down.

At this time, the young lady of the apprentice knight was dragging her chin with her small hands, sitting across the table, with a pair of beautiful big eyes wide open, looking at the potion in the test tube with a curious expression.

"What is this?" Seeing that Rollin was no longer operating, she looked up and asked, blinking her pretty eyes.

"Elixir!"

Rollin turned around and explained, but it was nonsense!

Now the alchemy materials are not complete, he only refines brute force elixir and strong sulfuric acid, and the remaining two cannot be refined, otherwise his strength may increase significantly.

"Of course I know it's a potion, but what is it?"

Avrilan expressed her doubts and pouted curiously as she looked at him!

Young Master Luo Lin even knows alchemy? When did he learn it? How did she not know before?

"Want to know?" A smile tugged at the corner of Rollin's mouth.

"Eun!" The girl nodded as diligently as a chicken pecking rice.

Rollin took a bottle of potion and handed it to her: "Drink it and you'll know!" ”

"Huh?" Avrilla was stunned.

Luo Lin smiled, didn't bother to say, took a bottle and drank it himself!

The mouth was a little spicy and disgusting, but it soon became sweet, and then a stream of heat flowed from his throat into his lower abdomen, becoming extremely hot, as if his body had exploded, and a brutal force came out of his body.

[System Prompt: You drink the Brute Force Elixir, and your strength is permanently increased by 2 points!] 】

A ray of light suddenly appeared in Rollin's eyes!

The permanent increase in strength by two points is not temporary, and now with the previous twelve points of strength, he is already fourteen points!

Enough is enough!

Fourteen points of strength at just two levels, which is an attribute only a warrior has, the Witcher...... Of course unlikely!

It's a pity that this potion is only effective for the first time, and it will lose its effect the second time, otherwise it can be refined more.

Avrilan was a little surprised to see him drink it, and poured the letter into her mouth!

Soon, she choked violently on the spicy taste, coughed several times in a row, turned pale, vomited several times, and waited until she came back to her senses before she quickly raised her head and stared at her hands, with a hint of wonder in her eyes.

"I, I, I...... My power has grown? Master Rollin! My strength has grown! ”

It seemed that she had already felt the power of the potion, and Miss Trainee Knight was shocked and exclaimed in surprise, feeling warm inside herself.

"Hmm!"

Rollin nodded, putting away the remaining bottle of the potion.

She is a probationary knight, and her sense of strength will naturally be more obvious.

"Uh...... Is this a brute force potion? Young Master Luo Lin, what did you just make a brute force potion? ”

Avrilan looked at him in surprise, her tongue curling a little.

"What's wrong with that?"

Rollin turned his head to look at her seriously.

Seeing that he was staring at him seriously, Ai Weilan's heart beat violently for no reason, and hurriedly said embarrassedly: "No, no, hehe, Young Master Luo Lin, when did you learn alchemy, why didn't I know before?" ”

"Just learned!"

"Oh!" Avrilan laughed happily, feeling very happy.

Luo Lin didn't pay attention to her anymore, and took out the green alum, put it in a test tube and lit it, refining it into strong sulfuric acid, although his venom arrow is powerful, but the acidity is not enough, it is okay to encounter low-level thieves, you can kill with one hit, but in the face of the living dead or high-level wizards, it is troublesome, you must use strong acid.

Soon, he quickly got busy, and it took more than ten minutes to refine a dozen points of strong acid venom.

Seeing his serious look, Avrilan blinked her blue eyes and didn't bother him, curiously staying aside and curling her fingers.

When Luo Lin's refining was finished, she suddenly raised her head, and her eyes lit up.

However, at this time, Young Master Luo Lin did not speak, but a trace of solemnity suddenly appeared on his face, tilting his head sideways as if listening to something, after a while, his face changed slightly, and he quickly poured the strong acid into the empty bottle, wiped out the alcohol lamp, and pulled her aside to hide.

Avrilan was taken aback and was about to speak, but Young Master Rollin reached out to cover her mouth and motioned for her not to speak.

Avrilan was slightly surprised, and frowned.

The room quickly fell silent, and it didn't take long for a series of faint footsteps to be heard outside the hallway.

Avrilan raised her head in surprise and looked at Young Master Rollin, only to find that he was making a silent gesture to herself, but she quietly climbed to the window.

His body faded away, merging with the dimly lit room.

At this moment, the door of the room was suddenly gently pushed open, revealing a gap, and a dim ray of sunlight shone down.

Avrilan was stunned, and she didn't dare to breathe, holding her breath.

However, suddenly, with a "boom", I saw Luo Lin suddenly rush forward, covering the mouth of a man in black with brute force, and swinging a sharp dagger at his neck.

Lurk, cut your throat!

With two simple moves, the blood soared rapidly, and the thief who sneaked in fell silently in the blood.

Avrilan was so shocked that she almost screamed, but when she looked up, she saw Young Master Luo Lin put the thief on the ground with an expressionless face, and turned back to make a silent gesture to her.

"Who is he?" Averlane's face turned pale.

"Rattlesnake!" Luo Lin replied in a deep voice, his eyes were cold, he glanced at the thief, quickly pulled her up and pushed open the door, and quietly walked out!

The two of them came to the corner of the corridor silently, looked in the window, and saw that seven or eight black-clothed thieves had appeared in the hall of the castle, and they seemed to be quickly overturning the bookshelves and tables in the hall.

"Not here, damn it, not here!" A leading masked man flipped a pile of books to the ground and said through gritted teeth.

"Search for me!"

Seven or eight thieves quickly got busy.

"Do you know that person?" Rollin thought for a moment, then turned back to Avrilan and asked, he had very few memories of the original body in his mind, many of which he didn't remember.

He ...... He's like, I'm a little familiar, he's covered his face! Avrilan lowered her head and pondered, and after a while, she suddenly sounded: "By the way, I remembered, this person must be Young Master Shengpei?" ”

"Young Master Shengpei?" Rollin was stunned.

"Uh-huh, doesn't Young Master Luo Lin remember? Young Master Saint Pei is the son of Master Droe! Avrilla said in surprise.

"Oh? I understand! Rollin frowned!

To be precise, this young master of Saint-Pés is still his cousin, Rollin's aristocratic father is called Del Farrell, and there is an uncle named Dro Farrell, this person is not a good person, he is lazy and lazy, a woman of a good family, who loves to do some things like to steal chickens and touch dogs, once molested the proprietress of the cattle slaughter inn, and after encountering resistance, he almost beat the proprietress of the cattle slaughter inn to death, and after being known by Del Farrell, he was furious, and gave him a hard lesson and drove him out of the field town.

It is said that after Droz was kicked out, he had a grudge against their Rollin family, and the death of Rollin's father Derry half a year ago was the result of their intervention, and now they are back, not knowing what they want to find.

"The story of the two Derridro brothers of the Farrell family, uh...... Family ethics dramas, it seems to be a little interesting, what exactly are they looking for? Rollin muttered to himself, frowning, and said something funny, but there was no trace of amusement in his expression.
