After thinking for a moment, Arrow suddenly noticed that Coco next to him was looking at him worriedly, and hurriedly smiled and said, "What's wrong?" ”

Coco hugged his steel staff: "Brother President...... Is this really okay? You look like you're worried...... Those two soldiers, I don't like them, they give me a bad feeling. There is a feeling of being unforgiving. ”

Arrow laughed, reached out and touched the little girl's head, and said, "Okay, okay, don't think so much." They are regular Imperial soldiers, and it is understandable that they are not polite to us small country guilds. By the way, what did you just come out of to me for? ”

Hearing Arrow mention this, Coco finally remembered his purpose and immediately put what had just happened behind him. She held up the bottle of therapeutic aerosol she was holding in her hand and said, "This is the therapeutic aerosol that Brother Guild brother gave me for self-defense, but it looks a little strange now. ”

"Strange?"

For a moment Arrow didn't understand what this meant, he took the glass bottle, picked it up and looked at it.

Only then did he realize that the healing aerosols that were supposed to be gaseous inside were now slowly condensing into liquid?

This scene made Arrow a little nervous, and he quickly turned his head to look at the therapeutic aerosol on the shelf behind his counter...... More or less, there are some states that are beginning to condense into liquids.

"What's going on?"

Eero hugged all the healing aerosols down, looking a little nervous. You know, it's all money! Now that these problems have arisen, they are all digging for his money!

"Napa! What's going on? Napa! ”

The big lazy cat that was sleeping with Masaki was caught off guard by such a yelling by Airo, and it got up slowly, its ears obviously drooping because it had not slept enough. But when it saw Arrow rushing towards him, he suddenly woke up, and his body instantly floated backwards, hovering in midair.

"What?! What do you want?! ”

"I'm just going to ask you what the hell you're doing! What's going on?! ”

Arrow raised the medicine bottle in his hand and pointed at it, his face full of nervousness.

Napa floated slowly over with vigilance. After seeing the situation inside the potion bottle, the ears that had been pricked up because of vigilance drooped again, and said listlessly: "Oh, it's expired, what's the big deal." ”

"Expired? What does expired mean, hey! ”

Arrowco couldn't accept this answer, and his voice grew louder and louder each time.

Napa was a little impatient, and after circling for a moment, she flew directly into Coco's arms over there, and lay down comfortably. Coco hugged her nervously and excitedly, not daring to move.

"It's literally expired. You put the healing aerosols on the shelves, they are not refrigerated, they are not protected from direct sunlight, and the temperature in our guild is quite warm, of course, the healing aerosols are easy to expire. ”

Airo rushes over, he can't catch the cat, but he can grab Coco's shoulders with both hands, and the light is fierce. This appearance did not scare Napa, but it made Coco's face crimson and her calves and stomach weak.

"Why does your alchemy expire?!"

"Nonsense, have you ever seen a medicine that works forever? Since the food in this world can expire, and the corpses of the dead will slowly decay, why don't the potions refined by alchemy expire? ”

The corners of Arrow's mouth twitched, "Then why didn't you tell me before?!" ”

Napa's ears pricked up slightly, and after a moment, slowly drooped again: "I don't think this thing needs to be told, right?" Isn't it common sense that potions have an expiration date? And just like food, the best way to preserve it is to keep it cold, dry, and dark. It's the same thing that wants to enter the human body, so it shouldn't make any difference if it's stored in the same way. Do I need to ask you this kind of common sense question again? ”

Arrow had to admit that he hadn't thought of that.

But when he heard the cat say this, he felt as if that was indeed the case.

In the final analysis, the root of the problem was that he had not been exposed to the shelf life of alchemy at all when he was in school. Thinking about it, the magic books and alchemy books he could read were the simplest and most basic, and there was no need to introduce such things as expiration dates. It's like a cookbook doesn't say how much time a snack lasts after it's made.

However, this unpleasant state of mind really makes Arrow uncomfortable.

"Napa, you...... Do you really know how to use 'common sense'? ”

Hearing that the sound was not quite right, Napa poked her head out of Coco's arms to take a look, but the cat prick up its ears in fright.

I saw that the current Arrow squinted his eyes, and his face was full of that kind of "absolute innocence and kindness" smile. This smile is even more commercial than a commercial smile!

This expression made Napa's fur explode, and the cat became a little nervous, and said, "That...... This is indeed common knowledge for any magician. I think...... Ordinary people should ...... It should also be ......"

Arrow clapped his hands and smiled, "It's okay. Coco, starting tomorrow, all three meals a day for our vice president will be turned into the freshest raw milk. Since quality is so important, of course, we must give our vice president the freshest food. ”

"Wait! I understand! I forgot to tell you the expiration date! I admit that I am wrong! Don't change my food! ”

Now, it's finally Napa's turn to hurry.

Coco laughed: "Vice President, I thought you could eat anything, but I didn't expect you to hate raw milk?" I also hate it, it smells terrible, full of feces and urine, and there is a milky smell, and it doesn't look very healthy, and sometimes there will even be some cow dung and cow urine floating on it. I used to taste a little bit when my mom and dad took me to milk, and I drank a little bit, and then I had diarrhea that day. ”

Napa looked nervous, and she floated out of Coco's arms and said, "Don't change my recipe!" Iero, I really like the milk you cook every day, and you strain it cleanly, so don't ignore my three meals a day. It's my fault, and I want to make it up now, how about it? ”

Arrow sighed, and the smiles on his face finally disappeared and were replaced by a wry smile: "Say it earlier." What to do with these therapeutic aerosols? Can it still be sold as a regular healing potion? ”

Napa flew over and looked at it for a while, and said, "No, once it fails, then these liquids are just ordinary dregs of water, and drinking them will not only not treat the body, but will cause damage to the body." And I can't guarantee the taste. ”

It's all money......

Airo looked at these healing aerosols with pity, and looked sorry.

In this way, it is impossible to let cocoa refine some therapeutic aerosols and then store them as stock, the more you save, the more money you will lose after expiration.

As Arrow looked helpless, Napa continued to circle the potions while thinking in silence. After a few moments, the cat suddenly seemed to think of something, and stretched out its claws and raised them high—

"But don't be too anxious, although these ineffective potions have no healing function, on the contrary, they can be used as 'reverse serums'."

Arrow: "What do you mean?" ”

Napa's paw pointed to the floor, "Isn't that bloody worm still unable to find a way to extract its essence?" This is because of the lack of magic power of our magicians. The knowledge reserve is also not rich enough. ”

Coco's face flushed, and she lowered her head a little shyly.

"But, with these reverse serums, you might be able to do it. Moreover, the venomous cyst gland of the rotting spider you brought back last time was also able to extract the toxins from it in this way. Go and take that bloodworm and that venom gland to the alchemy room. ”
