"He is worthy of being the Holy Son of Nature who is famous in the Continent. The magic doctor shook his head and tasted the rock sugar cherry, "This strange little fruit is indeed good, and it is no problem to cure this magic power dissipation!"

Gangu Yu smiled: "Hearing the demon doctor senior say this, then I will be relieved." ”

"But just taking it directly, its effect is not optimal. I'm afraid that if His Royal Highness recovers, it will have to wait many months. However, without a storage ring with a high time flow ratio, this fruit will spoil in a few days, right?"

The magic doctor looked straight at Gan Guyu and said, "Why don't Young Master Gu Yu give this little fruit to the old man, and let the old man dispense medicine for His Royal Highness? This is also more conducive to the preservation of the medicinal effect of this small fruit." ”

Lucas pursed his lips and said what the demon doctor thought: "You actually want to use Xiaotaniyu's acerola cherry to develop a new medicine, right?"

"But old decay can also make this little fruit exert its maximum effect, and shorten the time for His Royal Highness to recover!" said the demon doctor without hesitation.

Gan Guyu looked at Yin Yimo on the side, who said without thinking about it, "Listen to you." ”

Gangu Yu smiled, took out a bag of acerola cherries and handed it to the magic doctor: "If the predecessors can really develop a good medicine based on this, I will provide more acerola cherries." ”

"Thank you!" the Magic Doctor smiled, putting away the acerola cherries, "The old man needs a quiet, spacious place to conduct research. ”

Lucas, Yin Yimo, Qiuyi, and Madison hurriedly shouted in unison: "It's best to have a place with a defensive magic array!"

Gangu Yu was stunned for a moment, and then understood what everyone meant, and his eyes changed when he looked at the demon doctor. Needless to say, this must be a famous alchemist who specializes in the production of unstable compounds.

"Well, I really have one of such a place. Gangu Yu thought for a moment. Suddenly, his eyes lit up and he said.

He then led the doctor to a small building in the northwest corner of the Wizard's Academy, where he used his magic mark to open the door to one of the rooms.

"This is the lab assigned to me by the academy, but I haven't used it yet. Gan Guyu introduced, "What do you think of the seniors?"

The Magic Doctor looked around. I saw that this room could only be described as a house with four walls, nothing but an experimental table, and a thick layer of dust everywhere. But he nodded: "It's okay!"

With that, a diamond jar appeared out of thin air in his hand, containing some unknown black substance. The Magic Doctor opened the lid of the jar and poured the black substance directly on the ground. Only then did Gangu Yu discover that it was a viscous liquid that looked somewhat similar to jelly.

Before he could ask a question, a scene happened that surprised him.

I saw that the puddle of black substance seemed to be alive. It quickly flows on the flat ground, sometimes spreading and sometimes shrinking, and automatically deforms when it encounters a gap in the corner. However, as long as the black substance passes through, it will become bright and clean, and the effect is many times better than that of a vacuum cleaner!

"What is this?" said Ganguyu, surprised.

"It's just a potion concocted by the old man, and you can clean the house by yourself. The magic doctor's face was full of ostentation, "Carving insect skills." Nothing. ”

Gangu Yu blinked: "It's so amazing, but after cleaning the house, how can it be recycled?"

The Magic Doctor just smiled and didn't speak. After the black substance had cleaned the room, he slowly took out a small bottle and dripped a drop of the dark red liquid on the floor.

In an instant, the black substance that was quietly staying in the corner of the room was like a cat that had seen a mouse, and quickly pounced on a drop of dark red liquid, and quickly gathered into a ball on it. He was then re-placed in the diamond jar by the Magician.

"A small jar of something like this is enough to clean the whole building. The magic doctor didn't forget to show off, and then took the jar back in his hand.

Gangu Yu's eyes lit up: "So, you can put this thing in the house to keep the room clean for a long time?"

"That's true in principle. The Magic Doctor nodded. "Well, for the time being, this thing can only be used in places where the interior furnishings are relatively simple. ”

Gangu Yu's heart moved: "What do you mean?"

"That is to say, this thing has a strong cleaning ability, and it has the ability to climb, and even the dust on the ceiling can be removed. "But in addition to dust, water, oil, food residue, etc., it can also devour and remove ......."

"Understood. Gangu Yu's head was full of black lines, interrupting the magic doctor's explanation.

He had wanted to ask the Magic Doctor for some of this black substance to perfect the cleaning of the vitamin food stalls, after all, water magic alone was still quite laborious in removing oil stains.

But if you don't pay attention and let this thing crawl onto the table, the food on the table may not escape its claws. It would be a disaster if it snuck into the vitamin kitchen, which is usually stocked with liquid seasonings and oils.

And, who knows if this black substance will knock over the small items such as wine bottles and dishes displayed in the vitamin food stalls during the cleaning?

It seems that this thing has strong limitations! Gan Guyu secretly pouted, dispelling his previous plans.

But the magic doctor seemed to think that Gangu Yu was very interested in the potion he concocted, and immediately took out a lot of bottles and cans like offering treasures, and introduced them to him one by one.

As a result, Gangu Yu saw that the invisible potion could only show the handwriting when soaked in a special matching potion, but when this potion encountered ordinary water, it occasionally spontaneously combusted. There are also drugs that can treat polio but may cause myopia, and drugs that can treat infertility but make people only give birth to baby girls.

Gangu Yu's eyes have become infinitely cautious when he looks at the magic doctor, are you sure that the potion you made with acerola cherries is edible?

"Don't worry, as long as there is no medicine to solve the side effects, the old decay has not been used on humans. ”

Seeing the jealousy in Gangu Yu's eyes, the demon doctor hurriedly explained: "You know the Tongtian Demon Ape, right? The empire occasionally helps the old man to offer a high reward for the live Tongtian Demon Ape, just to provide enough experimental samples for the old man." ”

Gangu Yu secretly breathed a sigh of relief, no wonder when the old man proposed to use acerola cherries to develop new drugs, he didn't see anyone stopping him. He nodded and asked, "Then you are doing research and development here, do you need me to catch a few Heavenly Demon Ape for you?"

"Thanks, but no. The magic doctor waved his hand, "The old man has already sent a message to his assistant in Guangyao City, asking him to bring a batch of them to the old man." Oh yes, Your Majesty brought you a letter when he sent the old man to Cyprus. ”

With that, the Magic Doctor pulled out a scroll with a magic imprint. Such a scroll can only be opened with a specific magic mark, and it is obviously a secret letter that can only be viewed by Gangu Yu alone.

Gangu Yu was a little surprised, thanked him and took the letter, and did not open it immediately, but put it away first. The magic doctor said: "Okay, the old man is about to start the retreat, Young Master Gu Yu, please take care of yourself!"

"Alright, I'll take my leave. Ganguyu nodded, and left the lab. (To be continued.) )
