Jiang Yu walked unusually simply.

Dr. Duzem looked at her departing back with a worried look on his face, but he didn't say much. The old servant next to him, Konstantin, looked at the witch, and then at his own young master, and stopped talking, but in the end he didn't speak.

Zheng Qing stood in place and was stunned, and hurriedly put away the cardboard box on the ground, wanting to leave with the witch - in his opinion, since the doctor had already checked the elves and there was nothing wrong with it, there was no point in him staying here.

Besides, he also wanted to catch up with Jiang Yu and ask her what the problem was with Dr. Duzem before, and what her plan was to turn into a cat trap to trap the murderer.

However, as soon as he stood up with the cardboard box, he was grabbed by the arm by Dr. Duzem.

"Did you feed the elves anything before you came here again, or did you do any magic on them?" Dr. Duzem grabbed Zheng Qing's arm and stared at the young public scholarship student tightly, his tone became a little serious, "Did you prepare any potions to feed them in private?"

"What are you going to feed them? No!" Zheng Qing was a little confused by Dr. Duzem's question, and after thinking carefully for a long time, he replied in a very affirmative tone: "They didn't eat anything except dew and flower essences...... And you've told me about it repeatedly, and I definitely didn't feed it casually...... In addition, the people in our dormitory also know the severity, and no one feeds them indiscriminately. ”

"As for magic...... What strange magic do you think our group of first-year wizards can do to these elves? Speaking of this, Zheng Qing simply took out his law book and flipped it in front of the doctor: "Ah, these above spells are the results of my study in the past few months...... The most proficient is the Bondage Charm, and the most advanced spell is the 'Yuanchen Guardian Charm' - the Yuanchen Guardian has only practiced its pre-spell for a while, and we haven't learned when to use it. ”

Dr. Duzem frowned, and while listening to the babbling explanations of the publicly-funded students, he opened the law book in Zheng Qing's hand and searched carefully.

While watching, he muttered, even if it was impossible, not magical.

"What's going on? where is the magic?" the young student was very curious.

The Doctor didn't answer his question immediately, but asked something else: "The elves were asleep when you handed me the box before, right...... Why did they sleep?"

As he spoke, he pointed to the cardboard box that Zheng Qing was holding in his arms.

Zheng Qing lowered his head, and in the box, the elves wrapped their bodies with their wings again and fell into a deep sleep.

"What's so strange about that. Zheng Qing raised his head, feeling a little inexplicable, and a little more irritable in his heart: "We have hung a lot of charms in the paper house to maintain temperature, prevent noise, and calm the mind, so as to maintain the paper house in a constant temperature and humidity state. In that environment, even a dragon would fall asleep, let alone a group of elves...... This should not violate the previous instructions of the predecessors. ”

"That's all?" Duzem asked.

"You can see for yourself. Zheng Qing stretched out his hand and handed the cardboard box to the doctor, and at the same time asked, "Is there anything wrong?"

Dr. Duzem did not take the cardboard box, but continued to think with a frown, muttering as he thought, "No, there is nothing wrong...... Or rather, it's not bad, it's wonderful! It doesn't get any better than that. ”

"Wonderful?" Zheng Qing raised his eyebrows—he felt that Dr. Duzem had been speaking a little inverted and illogical from just now until now—and the young wizard couldn't help but turn his face sideways and glance at the old servant not far away.

Konstantin paid no attention to the conversation here. He was directing a pickaxe to loosen the soil for the nursery in the greenhouse, and beside him, several copper kettles of different colors filled with water, pesticides and fertilizers were floating in the air, clinking against each other, waiting for the old servant to summon.

"yes, that's great. Out of nowhere, Dr. Duzem pulled out a quill pen, turned it upside down, held the tip of the pen, and then reached into the cardboard box with his long feather, scratching a sleeping elf.

Although the elf had its eyes closed, it raised its hand very quickly and slapped away the feathers that had rubbed against him.

"See, did they not slow down in the slightest, they really just fell asleep. As if proving something, the doctor turned to look at the young student.

Zheng Qing looked dazed: "Otherwise?!"

"When you first handed me the box, I watched them fall asleep, thinking that they were starting to fall into chaos because of the diminishing efficacy of the medicine. The Doctor explained, turning the quill upside down, and drawing out of thin air, writing a series of smooth runes and derivation formulas in mid-air, and said at a rapid pace:

“...... But when the test results came in, I knew I was wrong. The situation of these elves is very good, and the good ones are incredible. They are in almost the same state now as they were when they first took their medication. There is no sign of diminishing efficacy at all. ...... This is a very abnormal situation. ”

There is no need for him to say it, Zheng Qing also knows that this is a very abnormal situation.

Gongfei held his breath and stared at every scratch left by the quill in midair. Unfortunately, although he could recognize that the Doctor was doing a probability analysis, he could barely read a word except for the symbols in the formula—in popular parlance, he knew every word, every symbol, every number that the Doctor wrote, but he couldn't read it when it was connected.

Dr. Duzem didn't seem to have any intention of solving the young wizard's doubts, but deduced and said something at the same time:

"It stands to reason that now that we have reached the end of the potion of potions, these elves should be showing symptoms of drowsiness, unresponsiveness, and confusion...... But according to the table you recorded, and the results of my examination, they did not show any of the above symptoms at all. ”

"It's very abnormal, very abnormal. ”

"But it's not entirely impossible. ”

"All impossibilities aside, the remaining one, if unbelievable, is a fact - for now, the only thing that has had a deep interaction with these elves and will have a clear impact on them is you. ”
