"Desert Eagle, go and get ready, and set off early to return to Shadow Peak. We'll just take care of the matter on my father's side. Zhao Lin suddenly remembered the adventure that Yan Moying said, so he couldn't wait to let him go.

Yan Moying left Hualuan Palace.

A moment later.

"Come out, come out! Brother Zhaolin, come and see! Yun Keyou exclaimed excitedly.

Zhaolin immediately walked over, only to see Yin Ruchen looking at the prescription he had just taken out of the small wooden box, with a happy face. In the smell of Wuxiangsu, he saw that although the recipe in Yin Ruchen's hand was still the same piece of paper just now, words appeared on it! That's the name of some herbs!

"Why is this happening? Just now, why are the words missing? Zhaolin couldn't help but be curious when he was excited.

"The words on this recipe are not written in ink, but in something that reacts with umami. When it reacts with the nut, the word will show a black color, and without the nut, the word will disappear. Yin Ruchen explained.

Indeed, as Yin Ruchen said, the words on this recipe were written by Feng Jin Lei with a thing called "Difan Branch" prepared by himself, and the small wooden box where he stored the prescription was also specially made, with excellent sealing, which was by no means comparable to ordinary wooden boxes. When the local fan branch is in the environment of black incense, it will naturally be like an inkblot, and when the prescription leaves Feng Jinlei's box and is exposed to the air for a period of time, the color will disappear.

"It's so interesting, Sister Yin is so good!" Yun Keyou clapped his hands and said.

"Huh? I see! Zhaolin said, "Miss Yin, now that the two pairs of prescriptions are here, you can quickly see what the problem is!" ”

"I figured out what the problem was, but I still need to give it a try." Yin Ruchen looked at the two prescriptions, frowned slightly, and said, "Mr. Feng's prescription doesn't need to be tried, I already know the effect of the medicinal materials on this recipe on people." Now what needs to be tried is Master Sun's recipe. In addition to the medicinal materials mentioned in it, you also need some cinnamon yellow. ”

"I'm going to bring those herbs and Guijinghuang!" Zhaolin originally wanted Yin Ruchen to go directly to the imperial pharmacy for the test, but he thought that if she was allowed to go there for the test, if it took a little longer, it would arouse the curiosity of more people, and the more hidden the matter was, the better, so he decided to get it himself.

"Guijinghuang, I'll pick it myself." Yin Ruchen said.

"Then I'll go to the pharmacy to get the herbs." Zhaolin looked at Yin Ruchen and finished speaking, said hello to Yun Keyou with his eyes, and went out.

"Huh? Guijinghuang is just a very ordinary plant, and it is not a medicine, what do you want Guijinghuang to do? There is no mention of Gui Jinghuang in the two recipes! Yun Ke Youqi said.

"I'm going to extract something from Guijinghuang." Yin Ruchen said.

"Oh......" Yun Ke looked at Yin Ruchen as if he didn't understand, "Go quickly, go ......"

Yin Ruchen felt that Yun Keyou's expression was very cute, smiled at her and went out.

As soon as Yin Ruchen went out, Yun Keyou shrugged his shoulders in the direction where Yin Ruchen went out, and said to himself: "I still don't understand......"

Yin Ruchen finished picking Guijing Huang, and when he was walking on the way back, he suddenly heard someone behind him shouting: "Ruchen!" ”
