As soon as he said this, not to mention Nangong Ao, the other people present looked at each other for a while. I think this thing is a little weird, if one or two people go in and see the wind and the moon, and they don't remember what they look like after they come out, then that's it. It can even be said that there are extenuating circumstances.

But all the people who went in and saw him did not remember what he looked like when they came out. That's a big problem!

This is obviously a problem in itself!

The military general kneeling in the center of the study. also slowly realized this problem, he frowned and looked at Nangong Ao, but he didn't say anything. I was originally sure that I couldn't leak secrets, but now I slowly began to be unsure!

Nangong Ao was silent for a while, and came back to his senses after a while. He turned his head to Zhan Nan and Zhan Bei and said: "Go and get the smoke soul incense!" ”

Zhan Bei was stunned for a moment, and immediately reacted to what the prince suspected. Quickly went to the study, took the smoke soul incense, and lit the incense under the signal of Nangong Ao's eyes. After a while, the incense slowly spread throughout the hall. After making sure that everyone could smell this smell, Nangong Ao asked, "Is this smell familiar?" ”

The other generals all shook their heads blankly. This fragrance is very light, a bit like the fragrance of poppies, but they have already thought in their hearts that this is not a great fragrance, so they don't know why Nangong Ao asked this.

However, the military general kneeling in the center of the main hall suddenly changed his complexion! He raised his head with an almost pale face and said, "Lord Wang! This fragrance is very familiar! The last general is sure that in the room of the wind boy that day, the last general will definitely smell this smell! ”

As soon as he said this, a look of surprise appeared on Nangong Ao's face.

The generals on the side swept over with some puzzled eyes. Ask: "Lord Wang, is there anything wrong with this incense?" "Why don't they feel almost anything wrong?

Nangong Ao didn't reply, but only glanced at Zhan Nan. Zhan Nan received the instructions and spoke: "The smoke soul incense comes from the Western Regions, and it is a perfumer named Santu, who was sad after the death of his wife. In order to be able to see his wife in his dreams from time to time, he developed such an incense, which usually smells and does not have anything. I only have sweet dreams, although it is harmful to my body, but it is indeed a sweet dream. After smelling it for too long, it will become addictive and even die early. But in the end, the perfumer did not die once, but died in ......"

"Die in a tune!" A military general answered, although he didn't know much about spices, but he had vaguely heard such a story.

He didn't know what the specific name of that incense was, but he knew such a story about the development of spices for his deceased wife.

After the military general finished saying this, he continued: "That song is called the Western Regions Requiem, after smelling the incense and listening to such a tune. He trapped himself in a dream, never woke up again, and died in a sad dream! But what is the connection between this and this ......? ”

After he finished speaking, Zhan Nan continued: "A song that does not contain any internal force can kill people, which is naturally a very terrible thing!" Therefore, later, many people in the rivers and lakes studied this thing and found that they composed other songs, which would have different effects with this incense......"
