"I knew you'd laugh at me when I said that, but the old man seemed serious." Yan Moying said.

Zhao Lin looked at Yan Moying with some surprise, he didn't have time to think about it, he just hoped that this was true, and he would rather believe that it was true: "Anyway, this is the only way we know at the moment, Moying, you set off to return to Shadow Peak as soon as possible!" I'll send you five miles away from his house, and they'll escort you back when you're done." ”

"But the matter of Your Majesty's poisoning ......," Yan Moying hesitated.

"Where's the anime?" Yin Ruchen said suddenly.

She just looked at the wordless prescription and thought, why is the word on it missing, even though it is still that piece of paper? At this time, she suddenly remembered the tangy aroma when Feng Jinlei opened the small box, and felt that it was related to the smell. Although there is still a faint fragrance on this paper, it is very faint, and it is not easy to notice if you don't smell it carefully. Yin Ruchen knew that this was the smell of Wuxiangsu. This black fragrance can be refreshed when people are tired when they inhale it in moderation, and it will volatilize when exposed to air. Yin Ruchen thought again, what would Mr. Feng do if he put Wuxiang in a sealed box? So she asked for a test of wuxiangsu.

"I'll get it!" When Zhaolin heard Yin Ruchen's words, she felt as if she had found a clue, and immediately went to get Wuxiangsu.

"A small box with a lid is also needed." Yin Ruchen said.

"Both!" Zhaolin responded as he walked.

"Why, Ruchen, what did you find?" Yan Moying also felt as if things were about to take a turn for the better, and asked excitedly.

"Do you remember that when Mr. Feng opened the small wooden box, there was a strong smell of black fragrance in the box?" Yin Ruchen asked Yan Moying.

Yan Moying recalled for a moment, nodded again and again: "Well, it is!" ”

"When I was in Zigui Village, the smell of the black incense on this recipe was very strong, but now it is so faint that you have to smell it carefully, which proves that the black fragrance on the recipe has volatilized a lot." Yin Ruchen continued, "The most common use of this black flavor is to refresh the mind, so I am a little curious, why did Mr. Feng put the black fragrance in the box containing the prescription? ”

"yes, that's weird! It's the first time I've heard of the black flavor in the box containing the prescription! Is it to refresh the box? Yun Keyou also felt incredible when he heard it.

"So I think the disappearance of this word may be related to the volatilization of wuxingin." Yin Ruchen said.

"Well, it's quite possible!" Yan Moying heard Yin Ruchen say this and felt that it made sense.

"But I'm just speculating......," Yin Ruchen said softly.

"Here you go!" Zhaolin walked over with a bottle of Wuxiangsu and a small box with a clean lid, and handed these to Yin Ruchen, although he didn't know what Yin Ruchen wanted to use this refreshing Wuxiangsu for, he had an expectation in his heart, he knew that Yin Ruchen had many methods.

Yin Ruchen put the prescription in the small box, sprinkled the black fragrance inside, and closed the box tightly.

"What are you doing with the black incense in it?" Zhaolin asked curiously.

"Sister Yin thinks that the disappearance of the word is related to Wuxiangsu." Yun Ke leisurely said.

"Oh...... I'm just experimenting......" Yin Ruchen said.

Zhaolin understood a little, but she didn't fully understand her intention to do this, and seeing that Yun Keyou was here, she didn't ask any further, hoping that this would solve the problem.
