He.

At the same time, Rice's face changed suddenly, and then immediately returned to normal before everyone looked at him, and said calmly: "Don't think that by pointing the finger at me, you can exonerate yourself." I haven't entered this study at all today, and the only one who has come in is you, so how did I poison the Grand Duke?"

That's right, he didn't come in at all today, so how could he poison him? Everyone looked at Ling Feng again.

No one here wondered if Rice was in collusion with the guards, he had come in, and the guards said no. Because they all know that the guards of the Grand Duke's Mansion are not under the control of Rice, and all of them are loyal to the Grand Duke and obey Yu Lei's orders. And Ling Feng didn't question it because there was nothing to take advantage of, and if it really was, then they wouldn't admit it.

Ling Feng didn't answer Rice's question, but walked to the desk. Since this Les had never come in, he must have used some method to poison the study. And look at the place where the Grand Duke of Ott is lying, it is next to the desk, which means that this desk is the most likely place to be poisoned.

Wait, I seem to have forgotten to ask something.

"Miss Oran, was Grand Duke Otter lying on the ground when you first came in? Have you ever touched anything?"

When Nicole heard this, she replied, "No, the Grand Duke was lying on the desk at the time, and I thought he was asleep, so I wanted to wake him up." I didn't expect the Grand Duke, hmm...... He slid to the ground and didn't move. Hmm......" Speaking of this, Nicole began to sob.

"Then have you touched anything else?" Ling Feng asked with a frown.

Nicole wiped her tears and replied, "No!"

"Oh!" Since Nicole hadn't touched anything else, the scene was still intact, so Ling Feng began to observe everything on the desk, except for the usual tools such as the Four Treasures of the Study, there were also two stacks of documents.

Ling Feng guessed that one side had been reviewed. The other side should be untouched, as can be seen from the wax seal of the document.

At this time, Ling Feng flashed a thought, looked down at the pile of documents that had been approved, and after sniffing it, he took out a few documents. I put it to my nose and sniffed it, and finally pulled out one.

And so it was. When the poison is placed on the document, the Grand Duke who reviews the document in this way will definitely encounter it. In this way, he can be poisoned silently, and he does not need to be present, as long as he does not come in like Rice, he can avoid suspicion. Poisoning here is basically something that no one can find out, and in this world, this thing has not been tested yet. If Ling Feng hadn't been soaked in the medicine for a long time, he wouldn't have been able to identify this.

Although this kind of lethal scatter is ordinary, it also has a special place, exposed to the air, and will slowly disappear. Therefore, it must be sealed. And even if a person encounters this, if he doesn't care about him for a few hours. It will dissipate on its own. This makes it even more worrying that someone can find something out of the document.

If this is the case, how can the person who poisoned him be sure that the Grand Duke will definitely eat the poison in his mouth? Instead, he ate the poison as soon as he finished reviewing the document, which can be known from the fact that he only reviewed one document. Looking at the amount of documents he reviews, you can see that it doesn't take much time for him to review a document.

In this case, the Grand Duke must have some habit of eating the poison in his stomach from his hands.

Ling Feng didn't care about everyone's puzzled eyes, and just asked Nicole, "Miss Oran, did your Grand Duke make any special small moves when he was reviewing the documents?"

"Little moves? Oh, I remember. The Grand Duke likes to be in the middle of a document. Lick your thumb!" Nicole thought of this when Ling Feng asked like this.

"That's right! this Less ......," Ling Feng looked at Les.

Rice, who was at the door, laughed and said, "Haha. I didn't expect that. Today's matter will have someone like you come out to stir up the situation. Since you can find this, I might as well tell you directly, this poison is what I put on the document!" When Les took out the document, he knew that today's things could not go as smoothly as planned, and began to slowly move towards the door.

Regarding his movements, Ling Feng was looking at the desk at the time and didn't care. The others all looked at Ling Feng, and they didn't care about the side of the land.

At this time, the reaction of the study to this mutation could not be realized, and they all looked at Les blankly.

"Ling Feng, yes, I don't understand, how did you find out that there is a lethal scatter on that document, no one can do this by sniffing it a few times. Les was puzzled by this.

"I said just now that I make poisons, if I can't even distinguish such ordinary poisons, then I'm a fool!" Ling Feng said lightly.

"Les!" Lacey shouted in a deep voice as he drew his sword at Rice.

"Why are you doing this?"

"Why do you want to do this? Ask this dead old man, he won't give me anything. He begged me to lead troops against the rebels and I didn't agree, and let me guard this damn Ultra City, guarding his lair. It will also ...... Hmph!" Rice said coldly.

"That's why you're here?" said Lacey angrily.

"Isn't that enough?" replied Rice.

"I'm going to kill you ungrateful thing!!!" Lacey cursed and prepared to attack.

Les didn't care about Reis's movements, but laughed and said, "Do you think I only have this arrangement? Before I came here, I had the city guards surround this place!!Don't you want to escape from my palms, you all have to bury the old man!!haha"

Les had already backed away before Lacey could attack him, and he was as fast as Lacey.

"??" Lacey looked at Les, who was already in the courtyard, and didn't understand how he could suddenly have such a speed, when he was fighting against himself before, the speed was only half of what he is now, could it be that he was hiding his strength before.

"I don't understand, I might as well tell you, I never fought you with all my might. I used to hide my strength, but now it's my real strength. In fact, I was already at the realm of the Sword Master a few years ago, and you still think that I am only a high-level sword master now. Les laughed wildly, the reason why he dared to come in alone today was because he was confident in his own strength, although he was not as good as Lacey, but he could definitely escape from the Grand Duke's Mansion.
