Arrow and Coco enter the basement to remove the bloody worm, then take the rotting spider gland that Cream had taken from earlier and follow Napa to the alchemy room.

It's still the cauldron, and it's boiling again. Napa walked around the barrel and looked at the bloody worm inside, which had been pampered all this time, but it was much fatter.

"Okay. Coco, remember the alchemy formula you were taught earlier? ”

Coco was stunned, obviously a little nervous. She hurriedly took out a notebook from her bosom and quickly flipped through it, and it took a few seconds to determine the formula.

"Well, I ...... I remember! ”

Napa nodded and said, "I taught you to synthesize healing aerosols and magic aerosols before, which belong to the 'transformation' category in alchemy. This course ......."

At this point, the beast suddenly fell silent, as if it was considering what words to say to praise the poor little necromancer.

But after hesitating for a long time, it still shook its head: "All in all, you can be regarded as having learned." ”

Arrow couldn't help but get nervous: "Hey, why does your tone sound like it's terrible?" ”

Coco's eyes were red again: "I...... Am I bad? Am I ...... Is it a bad student ......? ”

Ai Luo hurriedly stepped forward to comfort him, and after finally stabilizing Coco's spirit, he immediately turned his head and glared at Napa: "Teach it well, don't do any evaluation system." ”

Napa sighed helplessly and said, "This girl's progress can only be said to be average, and I didn't say that she didn't study well." Of course, it is indeed a little worse than some genius mages...... But aren't most ordinary people also ordinary people? ”

Cocoa's eyes moistened again, and Airo hurriedly hugged her and patted her head gently. Then, he turned his head again and glared at Napa fiercely.

"Okay, okay. Ahem, Coco, what I taught you before was the most basic kind of 'transformation' in alchemy. Do you remember what the active ingredient of the transformation was? ”

Coco wiped her tears, walked over to Napa and said, "Transform...... It is to extract the required components of several substances, and through the combination of spells and methods, they are fused into another required substance. Transformation does not require a high level of materials, even if the raw materials are not good, it can be refined to a minimum of items. ”

Napa nodded: "It's quite familiar." That's right, like the Morning Star Grass, the Aggregate Flower and the Tear Vine. For example, if we get two high-quality Morning Star Grass and Aggregate Flower, but the third tear-eyed vine is of very poor quality, then it can also be transformed. It's just that the quality of the therapeutic aerosols that come out is based on the worst quality of the tear-eye vine. But this is not so good for the alchemy method of 'extraction'. If the quality of the raw materials required is not up to par, then it is not as simple as refining the finished product. Refining failures are the norm, and if you don't get it right, you will be able to refine something very unexpected. ”

Coco listened very carefully, look at this expression...... Arrow felt that although this little girl was not talented, she could only say that she was an ordinary magician's IQ. But as long as you are willing to learn, you can still make a difference.

"So, now go and give it these expired pills. These expired drugs can be used as adjuvants for reverse extraction. This method can be used to increase your success rate while your alchemy is not yet mature. ”

Coco nodded, and came to the barrel, looking at the slowly crawling bloody worm inside.

She opened a bottle and poured down the potion that had completely dissolved into water.

But as soon as the bloody insect touched these potions, it immediately shrank into a corner as if it had been burned, and refused to touch them at all.

"Uh...... It smells so bad......"

Arrow pinched his nose, a little helpless.

Napa also shrugged her shoulders: "It's rancid, it smells like this." Cocoa, did it eat? ”

Coco turned her face away from the barrel with a sad face: "This bloody worm won't eat it...... What to do? ”

Napa exhaled, "If you don't want to eat, you can't help it, you have to go through this step." ”

Looking at Coco's sad face, Arrow shook his head, and very simply rolled up his sleeves and walked to the barrel, reaching out and grabbing the chubby bloody worm.

The attack power of the bloody insects that are not in the group is really weak, and it can even be said that they are very afraid.

It twisted and twisted as it was held in Arrow's arms, but no matter how much the chubby body struggled, it had no effect. Arrow pinched its flesh and lifted its head to reveal its mouth full of tiny teeth, "Quick, pour in!" ”

Coco nodded hurriedly, opened a bottle of potion again, and stuffed it into this mouth.

As soon as these foul-smelling potions entered the body of the bloody insect, the little demonic beast immediately seemed to be hollowed out, and after a convulsion all over its body, it stopped moving. Seeing this, Arrow immediately turned the worm over to prevent it from spitting out the potion.

"Is it okay? Cacao. ”

Coco reached out and pressed the belly of the bloody worm, and after confirming the soft touch, the little girl turned her head with some concern and looked at Napa over there.

"Don't look at me, I've taught you how to do it, and the formulas are all in your notebook. These potions are designed to condense the essence of living beings and make them easier to capture. With your current strength, you should be able to do it too, so give it a try. ”

Coco nodded, closed her eyes, and silently chanted the incantation. After a few moments, she raised the steel staff in her hand and slowly inserted it into the bloodworm's stomach like a needle.

The Bloodworm's body trembled slightly, but there was not much of a reaction.

After about a minute, Coco chanted the incantation, and the steel staff began to pull outward little by little. At the same time, some scarlet gas wafted out of the stomach of the bloody worm.

"Enter!"

Coco pulled his staff and stepped on the pedals, plunging the steel staff into the boiling water. The scarlet gas also seemed to be pulled into the alchemy cauldron.

The firewood burned brightly under the pot, and the boiling water, which had been crystal clear, was now beginning to become cloudy and gradually turning a faint scarlet.

When Arrow looked closer, he saw Coco's forehead sweating and his mouth whispering incantations. Looking at the bloody worm in his hand, when all the scarlet gas entered the alchemy cauldron, it was as if he was holding only a skin bag in his hand.

After another five minutes or so, the boiling water, which had just been turbid, became clear again, and the scarlet gas that had been filled with it gradually condensed on the tip of the steel staff.

"Vice President, alright...... Is it? I feel like it's okay...... Will it be mushy after a long time? ”

Coco looked nervous, and it was clear that the steam of the boiling water had turned her little face red, but she didn't even dare to blink her eyes, staring at the staff in the cauldron.

Napa floated over and took a look, nodded, and said, "It's okay." This time I remind you that next time you have to pay attention to yourself, after all, I can't always be alchemy with you. ”

With Napa's consent, Coco quickly pulled out the steel staff. At that moment, Arrow smelled a smell that was all too familiar to him—

The smell of feces and urine.

"Woo——!"

This extremely strong smell of feces and urine is just the same as when my head and face were covered with bloody worm blood that day! At that time, it was still in the mine, and the place was large, but now in this closed alchemy room, Arrow had a feeling that he was going to be carried away by these smells!

Naturally, cocoa was also washed by this smell. With one hand over her nose and the other in her steel staff, she seemed to be caught up in the difficult choice of whether to let go or not to let go. Luckily, Napa picked up an empty bottle and stuffed the scarlet bead into the bottle, and the stopper was plugged. At this point, the smell can be regarded as completely dissipated.

"Oh my God...... It's a ...... smell Miss. ”

Arrow walked over, took the bottle from Napa's hand, looked at the small beads that were emitting a moving light inside, and then looked at the bloodworm corpse in his hand, which was completely devoid of vitality, and nodded, "However, the effect is significant." To be on the safe side, this thing doesn't have an expiration date, right? ”

Arrow asked warily.

Napa hovered over Arrow's head for a moment, sat down directly on his hat, and said, "I said, everything has an expiration date. The taste of this bead also has an expiration date. However, the expiration date of this thing does not mean that the smell disappears instantly, but that it dissipates little by little. I usually store it like this when I don't use it, so I should be able to store it for a long time. ”

After confirming it, Arrow put his mind at ease and set up the "Blood Bead."

And then there's the venomous sac gland of the venomous spider.

The whole process is similar to that of the Bloody Bug, except that the original forced medicine has become a smooth wipe of those expired potions.

Half an hour later, the Mermaid Song Guild finally extracted the first antidote to the Rotting Spider. Arrow was very happy, but Coco quickly picked up the pen and paper after extracting it, and began to write according to the bottle of antidote. Arrow glanced at it, and it was full of difficult magic formulas and graphics. Looks like it's the structure of this antidote, right?

"Done."

When the refining was over, Napa yawned and didn't seem to want to take care of it anymore, and after a few casual words, she flew out to find its cushion to rest.

Arrow looked at Huanxi with the Blood Orb and the antidote, but also carefully placed it in a gloomy closet in the alchemy room. At the same time, I secretly made up my mind that I would never be able to do two loss-making businesses in a row like today in the future.
