Liu Xiangyun saw that Yu Xi and Feng Yiyang came so quickly, and looked at the worried look in her eyes that was difficult to hide, and her heart was hot.

Since she revealed her identity as her own person, Yu Xi, the nominal daughter, has really been sincere to her, and has helped herself a lot openly and secretly.

It is said that people's hearts change people's hearts, and Yu Xi's sincerity is relative, so that Liu Xiangyun can't help but treat her differently and trust her in everything.

"I'm fine, it's Zhu Sixi, the housekeeper, who died violently in the firewood room today, you know medical skills, let you come to the house to see the cause of death." Liu Xiangyun took Yu Xi's hand and said.

"Zhu Sixi died violently in the house? But what's going on lately? Yu Xi asked, his eyes were clearly asking Liu Xiangyun, has your pregnancy been exposed?

"I found the Absolute Gu in my yard, and I told the master today. Zhu Sixi has always been responsible for loosening the soil and planting flowers, and the old man asked the maid to pass Zhu Sixi for questioning, but who knew that Zhu Sixi was found to have died violently in the firewood room. ”

Liu Xiangyun said it concisely and to the point, and Yu Xi immediately understood.

The implication is that Zhu Sixi's death is inseparable from Feng Qinglan, and I hope she will investigate it thoroughly.

Yu Xi followed everyone to the firewood room and went over to check on Zhu Sixi's tragic situation.

Zhu Sixi's face was bruised, the veins were conspicuously slightly protruding, his eyes were bulging outward like two copper bells, and his mouth was wide open, as if he was very frightened before he died.

Yu Xixin said, isn't this a zombie in an American movie?

She endured the nausea, walked over and lifted the corner of Zhu Sixi's short robe, and went to see his ribs.

Sure enough, there were two blue-purple marks on the ribs, as if they had been bitten by some sharp teeth.

Yu Xi's face was much more solemn.

"What's going on?" Gong Xun couldn't help but ask on the side.

"Zhu Sixi died of a rare Gu poison called the Imperial Worm. This kind of Gu is first fed to a worm that can bite people, or a cockroach, or a grasshopper, and if you eat this kind of Gu worm, you will definitely bite, and you will die in the process of biting. ”

Yu Xi remembered that there was a record of this in his father-in-law's "Materia Medica", and said calmly.

So he ordered people to pick up the firewood and grass in the firewood room little by little, and sure enough, a cockroach the size of a thumb was lying on the ground. Its belly had exploded, revealing its intestines inside.

"Come on, call everyone in the house over, and check one by one, who gave Zhu Sixi the Gu." Gong Xun was even more firm in his guess, someone must have leaked the news to Feng Qinglan when Liu Xiangyun was talking to him about the Absolute Gu. But now that he has no evidence, he can't act rashly.

"Not necessarily." Yu Xi seemed to have been prepared, and waved at Gong Xun. "When Zhu Sixi died, the murderer must have been present, and after the cockroach bit Zhu Sixi, a poisonous gas would be produced in his stomach, and then it exploded. In less than twelve hours, the murderer will be poisoned to death. Unless ......"

"Unless what?"

"Unless the murderer can eat a pound of mulberry leaves within six hours, but the murderer may not know that there is such a method, and the mulberry tree is unlucky, there is no mulberry tree in the prime minister's mansion at all, let's see who dies of poison tomorrow morning, and we will know who killed Zhu Sixi."

"Although there are no mulberry leaves, but ......" Liu Xiangyun wanted to say that the female red maids in the house have a weaving room, which is full of silkworms, not to mention a pound of mulberry leaves, there are also a hundred catties, and it is very convenient for the murderer to find it.

Yu Xi kept winking at Liu Xiangyun before she shut up.

"Let's find a place to park Zhu Sixi's body first, father, Erniang, you are frightened, I will send you back to your room to rest, and tomorrow the murderer will die of poison, and we will continue to investigate."

Without waiting for Gong Xun to say anything, Yu Xi hurriedly pulled one with one hand and went to Liu Xiangyun's residence.

After all, it was a family affair of the Prime Minister's Mansion, and Feng Yiyang didn't interfere much from beginning to end, just watching his princess from the sidelines. She works seriously, and her calm and indifferent appearance is too charming.

"What do you mean?" On the way back for a few people, the pregnant woman Liu Xiangyun followed Yu Xi in small steps, throwing everyone far away, and couldn't help asking.

Yu Xi quietly put her mouth to her ear and muttered a few words, and Liu Xiangyun understood what she was going to do.

"You're amazing." Liu Xiangyun couldn't help but applaud, this girl is so smart.

"Shhhh

Liu Xiangyun nodded hurriedly, and the two of them held their arms and pretended to leave as if nothing happened.

That night, the regent and his wife stayed in the prime minister's mansion and slept in the boudoir of Yu Xi's original Mingde residence.

Yu Xi naturally couldn't sleep at night, and kept waiting for news with his eyes wide open in Feng Yiyang's arms.

"Alright, let's sleep, good. I'll get you up as soon as there's any movement. Feng Yiyang felt distressed, and forcibly reached out to blindfold her and told her to rest first.

"Hey, Dabao, do you know what I'm doing?" Yu Xi was a little surprised, because Feng Yiyang watched coldly from beginning to end, and did not ask a word. Yu Xi thought that he was indifferent to the affairs of the Prime Minister's Mansion and didn't want to bother him with this matter, so he didn't tell him about his plans.

Feng Yiyang chuckled in a deep voice: "If I can't understand this, how can I be worthy of being your father-in-law." ”

"Will the murderer be able to see it too?" Yu Xi suddenly felt a little uneasy.

"No, if the murderer was so smart, he wouldn't have been killed with a knife, you wait."

Feng Yiyang pressed her into his arms and patted her on the back like a child.

Yu Xi was really sleepy.

After another half an hour, someone outside suddenly knocked on the door and said, "Lord Wang, it's all done." ”

Feng Yiyang was hesitating to wake up someone in her arms, but she had already opened her moist eyes and was about to sit up in her clothes.

This woman's execution ability is amazing, she will never be lazy when she really wants to do anything, where is like a princess who is loved by him, she is simply a soldier in the barracks.

Feng Yiyang looked at her and smiled, and reached out to take her clothes in the faint candlelight to help her put them on her body carefully.

"How can there be a reason for the prince to serve the princess and put on clothes." Yu Xi muttered a little shyly.

"Tell me every day that everyone in your world is equal, let me be equal to you, why do you say these things at this time." Feng Yiyang kept in his hands, helped her tie the belt of Luo's skirt, and said.

"But now it's unequal, it's like you're below me." Yu Xi retorted to him.

"Oh?" Feng Yiyang's tail voice rose, and the hand that was tying the belt paused.

"I'd rather be down there, after all, it's not tiring to lie down below." He deliberately misinterpreted her meaning, and Huang Yan opened his mouth to come.

Yu Xi blushed again, and trembled in disgust and snatched the belt back from Feng Yiyang's hand.

"Hahahaha, what's this. You are so open in other things, and you are ashamed to be like this when you get to bed. ”

Feng Yiyang finally couldn't help it, laughed and hugged her and kissed her twice, and the two hurriedly sorted out their clothes and went out to see the murderer.
