For the next few days, Polly and Master Durroux lived in the Fergus family.

Master Duru asked the Fergus family for a hut, and after arranging it into an alchemy room, he spent the whole day trying to restore the recipe for the beast control potion, and McCarthy Thompson's alchemy utensils were brought back.

Polly mingled with the younger generation of the Fergus family, cultivated together, read books together, and traveled to various places in the Viscount of Fergus together.

Among the Gray people, Sarah is the happiest for Polly and Master Duru to stay at Fergus Castle temporarily.

In the past few days, I have been playing around with Polly, and I have received all kinds of gifts, and I have a Sister Poli, which is called sincerely.

One day, at the White Stone Training Ground of Fergus Castle, after finishing her practice, Polly, who was sitting in the gazebo with Bernal and others, drinking juice, asked suspiciously.

"Why haven't you seen Gray when you've been cultivating for the past few days?"

Originally, she also wanted to judge Gray's current realm among the mid-rank blood warriors by observing Gray's cultivation, but she couldn't see Gray for a few days, so she finally couldn't help it and asked out loud.

"Gray usually cultivates alone in the open space south of the castle, and rarely cultivates with us."

Caroline explained.

"That's right."

Thinking of the incompatible relationship between her eldest brother and her second brother, Polly consciously stopped the topic and stopped asking questions further.

And as for Gray's identity, from Sarah's mouth these days, she has heard that one side is the child of the viscount's wife, and the other side is the child of the lover, and the relationship between the two parties is not good, and it is normal to have a mustard.

"Whew-"

With a sigh of relief, Gray finished his morning practice.

Drops of sweat hung all over his forehead, slowly sliding down his forehead.

"Master Gray, please use a towel!"

Just in time, the maid Barbara stepped forward and respectfully handed over the towel.

Gray took the towel, wiped the sweat from his forehead, and returned it to the maid, Barbara.

In the past few days, he could clearly feel the attention from the Marquis's daughter, Poli, because the other party's eyes would fall on him from time to time.

Of course, he was not narcissistic enough to think that the other party had that kind of thought about him, and in his estimation, the reason why the other party paid so much attention to him should be because of his performance in the battle of the viscount of Sidney Castle.

The performance at that time, among all the viscounts, was indeed too eye-catching, but at that time, in order to compete for resources for the Fergus family, he couldn't care so much.

Now he lives in the Fergus family, and the more the Fergus family receives from the Sidney family, the more benefits he will naturally have.

And the benefits are already being felt, since returning from Sidney Castle, the supply of blood from the Blood Beast has been increased to once a week, and an additional bottle of concentrated potion that you can't necessarily buy even with gold.

He hadn't taken the concentrated potion yet, so he didn't know what the effect would be for the time being, but increasing the blood supply to the blood beast once a week had undoubtedly increased his cultivation speed a lot.

Heading to the castle baths, Gray passed by a house, hesitated slightly, and finally couldn't help but be curious, stopped, and walked towards the house.

The door of the house was open, and Gray walked to the door, stretched out his head to look inside, and saw an old man in a gray robe with gray hair, who was busy intently between the bottles and cans, and this person was naturally the master of alchemy, Duru.

His hands are extremely flexible, constantly flying, mixing various liquids in proportion with great precision.

The liquid he mixed was bubbling and bubbling in color, first pale yellow, then dark yellow, then lilac, and finally deep purple......

Gray watched quietly, with curiosity in his eyes, is this the process of refining medicine by an alchemist?

It's quite similar to when he did chemical experiments in his previous life, but the other party's movements are too fast, even with the eyesight of his high-ranking blood warrior, it is blurry in his eyes.

Of course, this is just the appearance, as far as Gray knows, in the process of refining medicine, the alchemist needs to use the power of blood to perform a special alchemy technique, acting on the liquid medicine, and each step is different, and the technique will be different.

At this moment, the alchemist Du Lu stopped, picked up the vessel containing the dark purple liquid, and frowned as he looked at it.

"No, no, no, it's not like this, the components are all derived according to the derivation formula, there should be nothing wrong, the problem must be in the steps...... What went wrong? ”

Master Duru habitually muttered to himself.

Gray looked at it, although he had done chemistry experiments in his previous life, but it was average, and he could see from the current situation after he graduated, so he naturally couldn't see the problems in it.

"Gray!"

The voice of someone greeting behind him sounded, and Gray looked back, and saw that Polly was walking this way, and his face couldn't help but be bitter, and sure enough, in the next moment.

"Boy, what are you looking at when you're standing in the doorway?"

Master Duru's voice rang out.

Obviously, because of Polly's voice, Master Duru also noticed Gray's uninvited guest at the door.

Originally, with Master Dulu's strength, it could be easily discovered, but Master Duru was too involved in refining medicine, so he didn't find Gray at the first time.

"I'm sorry, Master Dulu, I'm a little curious about how the alchemist refines medicine, so when I pass by, I can't help but want to take a look."

Gray said cautiously.

This Master Dulu's character is not good, he naturally doesn't want to offend this one verbally, otherwise, if this person gets angry and slaps him to a serious injury, it will really be in vain, after all, to some extent, he is already a voyeuristic act.

"Hmph."

Master Duru is not good-tempered, and originally wanted to hurt Gray a few words, but thinking that he was still living in the Fergus family, he gave up after thinking about it.

And his alchemy is not so easy to be stolen to learn, if he is really looked at by someone, and he is learned by someone, then he, a master of alchemy, is too worthless.

Knowing that because of her own reasons, she almost let Gray be scolded, Polly walked up and spoke.

"Gray, do you want to learn alchemy?"

"Yes, but I don't have that talent."

Gray shrugged helplessly.

"You're pretty self-aware."

Master Duru sneered.

If you want to become an alchemist, and have great achievements in alchemy, talent is essential, and without talent, even if you work hard, your achievements are extremely limited.

As for the people who are active in various towns and can prescribe some wind and cold medicine and bruise medicine, they are not even pharmacists, they can only be regarded as ordinary people who know a few prescriptions.

If you want to become a pharmacist, you must at least have the ability to independently develop potions, and if you want to become a master of alchemy, you need to have the ability to develop potions.

"Miss Poli, are you done cultivating?"

Seeing that Master Duru had no intention of making trouble for himself, Gray looked at Polly and beckoned.

"Well, I just finished cultivating."

Polly nodded, looking at the container containing the purple potion in Master Duru's hand, and asked expectantly.

"Teacher, how is it, has the veterinary control potion been restored?"

"Uh~~, ah~~, it's still a little close!"

Master Dulu, who was still domineering just now, suddenly became embarrassed.

Probably he didn't think of it himself, after knowing the ingredients of the drug and analyzing the general refining steps, it took a few days to still not restore the beast control drug.

Thinking of this, he looked at Gray and asked.

"Boy, the last time you entered that wooden house, did you take away the utensils for refining medicine?"

"No, I just took away a manuscript, a blood method called "Wood Monkey", and those bottles of solution."

Gray said after a moment of reflection.

He is not afraid that after the other party hears the blood method "Wood Monkey", he will have the idea of snatching, and the blood method like "Wood Monkey" can only be regarded as an ordinary blood method, and there are many families.

For ordinary people, it is an extremely precious thing, but for the alchemy master Du Lu and the marquis's daughter Poli, the value can be described as extremely low, and there should be this kind of blood method in the marquis's family.

"But when we went this time, the room was touched, and I wonder if this man took some utensils when he left."

Gray wasn't so sure.

There were so many utensils on the long table that they didn't pay much attention to at the time, so it was not clear if any of them had been taken from them when they went the second time.

"Boy, wait a minute, let Viscount Fergus help me find out, see who went to that hut, and if they took anything, get it back."

Master Duru commanded.

"Okay, I'll tell my father when I get back."

Gray nodded.

"Teacher, in terms of steps, you have tried all the steps that you can think of, will the ingredients and proportions of the drug be wrong?"

Polly frowned.

"The ingredients and proportions of the drugs are all calculated according to the calculation formula in the manuscript, and there should be no mistake."

Putting the container bottle down, Master Duru shook his head.

"Could it be that McCarthy Thompson deliberately omitted or added some drugs to the manuscript in order to prevent the recipe of the control drug from being taken away?"

Polly said again.

"Deliberately adding or subtracting drugs?"

Master Duru thought with one hand on his chin.

"There is a possibility, this guy is a wanted criminal, ready to escape at any time, and he definitely does not want the formula of the veterinary drug to be obtained by others, and it is likely that he will add and delete certain drugs to the manuscript......"
