Who exactly threw the poison into the investigation? Knas had known this kind of thing for a long time, because poison was the one that Knas controlled his devil to throw.

These poisons will not kill people, but they can facilitate Knas to muddle the water. In the chaos, Knas can find an opportunity to get close to the dragon and put the dragon sleeping water he had earned a lot of money into the dragon's food, thereby increasing his success rate of killing dragons.

However, although Knus successfully disturbed the situation on the airship and successfully approached the dragon, the development of the matter was somewhat different from Knus' plan - the dragon has been staring at him since it appeared!

It's really hell, why did the dragon target me like this? Did he notice something? Feeling Oz's sight, Knus felt uncomfortable all over.

Oz didn't know who Knus was, but he clearly felt Knus' fear of him.

Why is he so afraid of me? Oz, with a hint of doubt, absorbed Knus' fear and followed the captain to the airship's kitchen.

The kitchen of the airship does not use open flames, and all heating is heated through a magical equipment similar to an induction cooker. Most of the food on the airship is cooked food, and it only needs to be heated to serve it on the dining table.

Oz and his group used the [Detection of Toxins] magic to detect the food boxes in the kitchen, and no toxins were detected.

"There are no toxic substances detected in the food box. Therefore, the possibility of food being poisoned from the beginning can be ruled out. Since the food was not poisoned, the time for the poisoning is after the food is taken out of the food box..." Knas was sharply observing the expressions of several chefs like a detective. "Chief Chef, can I ask you a question?"

The chef is a big man with a stubborn face. He looks more like a warrior than the chef. Facing Knus' inquiry, the chef's expression on his face was a little dissatisfied: "Why should I accept your inquiry?"

"Of course it's for the safety of the journey. After all, there are many big figures on the airship. If you don't investigate clearly, some unpleasant things may happen." Knas said and looked at Oz and Sashara.

"Answer our question." Sashara glared at the chef, and the aura of the high-level knight burst out, making everyone in the kitchen feel a palpitation.

Feeling the momentum of Sashara, Knus narrowed his eyes: This momentum... is stronger than Baron Solsia, and it seems that she is probably also a high-level knight!

Sashara stared at the chef: "You don't want to say that it's the poison you made, right?"

Sashara's suspicion made the chef very angry: "Just! I've worked on this airship for so many years and this has never happened!"

At this moment, the captain said to the chef with a serious expression: "Fode, please answer their questions."

The chef glanced at the captain and said with a reluctance: "Okay. I said that's it. After the chef prepares the food, he will hand it over to the waiter and will be delivered to the customer."

Knus: "That is, except for the chef, is the only waiter who delivers the meal the opportunity to get in touch with food?"

The chef looked unhappy: "That's it."

"So, you are the most suspicious..." Knas stared at the chef.

The chief chef glared at Knus angrily: "If you insult my professional ethics again, I will fight with you!"

"Sorry, sorry." Knus raised his hand and surrendered. "I just made reasoning based on the current information."

"Hmph!" The chef snorted coldly.

At this moment, Oz suddenly insulted: "Mr. Detective, you are also a magician. Then you should know that there are many ways to poison without realizing it."

Knus looked at Oz: "For example?"

"After invisible, drug it directly, manipulate the wind to drug it from a distance. There are also the legendary space magic, etc."

Knus looked at Oz. The expression on his face was a little stiff: "If you want to avoid being discovered, you must be completely invisible. At least you need to use the three-ring [advanced invisibility]; controlling the wind requires extremely high wind-type magic skills, which is probably difficult for ordinary magicians to do; space magic... I have only heard of this, and have never seen it. The three methods you mentioned are not something that ordinary magicians can do."

"I don't think there is any difficulty in this." Oz curled his lips and looked at Knus with a smile. "So, our Mr. Detective, after asking for so long, do you know who the murderer is?"

Knus looked at Oz's smiling expression and felt a little uneasy.

Knus took a deep breath and threw the anxiety in his heart out of his mind: "There is too little information now."

"You just need to tell me whether you know or not." Oz said with a smile, as if he had seen through something.

Knus' pupils shrank slightly when he heard Oz's words!

"You used [Detection of Lies]?"

"Yes." Oz smiled, "No matter who poisons it, you can always ask it if you ask it."

"That's it..." Knas closed his eyes.

"So, can I answer my question?" Oz stared at Knus step by step. "Do you know who the poisoned person is? Only answer 'know' or 'not know'."

A few seconds later, Knus closed his eyes and slowly spoke, "I don't know."

Knas lied, but did not detect lie. He seemed to be able to deceive the magic of [Detection Lies].

"That's it..." Oz was a little disappointed.

"So, let's continue to ask." The captain's expression seemed much more relaxed. "Since someone can use lie detection, it will be much more convenient for us next."

"Don't look for me. I have no reason to work for you." Oz refused without hesitation.

When the captain heard Oz's rejection, he was stunned: "This... aren't you worried that the murderer will poison again?"

"Not worry at all!" Ozzi said, "Just use the detection of toxins before eating."

Hearing Oz's words, the captain had no choice.

Oz glanced at the captain and Knus, his eyes rumbling: "But if this detective can answer a question, I don't mind working hard and help you."

Knus's hair stood up when he heard Oz's words!

"I'm not a detective." Knas smiled dryly.

Oz stared at Knus: "Why are you afraid of me?"

"Uh..." Knus's expression was stiff, "Ah haha, maybe it's because you are better than me."

"Strong?" Oz stared at Knus, "If it's strong, my sister should be stronger than me."

"Big, stronger than you!" Knas looked at Sashara on the side and was stunned. With the pride of the dragon, he should be disdainful to lie, so that is to say...

This woman who looks big and brainless is also a dragon! (To be continued...)
