Song Yao let go of her hands and dragged the Prefecture Overseer to the back.

"Miss, can you let me go? If you have something to say, just say it." The Prefecture Overseer felt very uncomfortable in her embrace and had no choice but to speak up.

Song Yao nodded his head, "You will be punished if you are discovered and Imperial Guard Fu's temper is not good. When the time comes, she will come to find you for some matters, and there will be no other way."

What else could the Prefecture Overseer do? He was already close to a hundred years old and was only waiting for his age to retire. Naturally, no one could offend him, so he said: "I understand, this matter will not be spread out."

Song Yao laughed: "That's good, you can be at ease, I will definitely speak a few more words of praise for you in front of Your Highness, maybe you will even get promoted or something like that."

The Prefecture Overseer sighed, "What kind of official? I am deeply grateful to be able to help me find the murderer without being punished by the Right Prime Minister. At this age, I can't be bothered to waste my time on anything else. I only hope to be able to find the culprit with the blessing of the heavens."

Seeing that he was afraid, Song Yao said: "Don't worry, I will definitely do so."

She wasn't sure, but she couldn't say something like that at this moment.

Gongsun Xiao saw that she and the Prefecture Overseer had caught up with them and asked: "What did you tell him?"

Song Yao said: "It's a secret."

Gongsun Xiao laughed, and clicked his tongue, "There are so many secrets between you and Your Highness? "How did I find out that you and I were full of secrets?"

Song Yao shrugged her shoulders, "I have my suspicions, and have been dragged into your group for no apparent reason, so I naturally can't say everything that I want to say. Therefore, I have a lot of secrets."

Gongsun Xiao sighed: "You woman, you really are …"

"How is it?" Song Yao asked.

Gongsun Xiao said: "Li Residence has arrived, go in."

Song Yao did not stay any longer and followed them into the Li Residence.

Li Wanji's younger brother was the Right Minister. His family controlled the silk industry in the capital, so he was a very rich man.

The furnishings in the house were even more exquisite and luxurious than Zi Yanghou's, there were fake mountains, flowing water, lotus ponds, all sorts of things.

Although Song Yao was shocked, she knew that this was not the time to appreciate the scenery.

She casually asked: "Li Residence is so luxurious, why does Young Master Li want to buy buns to eat? No one in their house makes buns? "

In response to their servants, he said: "Young Master said that the Su Family's steamed buns are unique and delicious. No one in the mansion can compare to you, and you even have to buy them yourself."

Song Yao understood, this person's goal was too clear, she just wanted to tease her.

The few of them walked through several courtyards before arriving at the scene.

The scene was Young Master Li's room. Nothing had been touched. On the table was a cup of cold tea, and on the floor was a broken porcelain vase filled with soy milk.

They were scattered all over the place and stuck to the ground.

The two buns only had one bite, and before they could swallow the mouthful in their mouth, they died from poison.

The coroner examined the steamed buns and bean curd milk, but did not discover any poison. He also examined all the items on the table. There was no poison in any of them.

The officials had even checked everything in the room, but they still couldn't find anything.

The poison in Young Master Li's body was arsenic, and it acted up very quickly. Logically speaking, the poison was very strong and it took a lot of effort to poison a steamed bun with it. Moreover, Young Master Li had bought all the steamed buns, so the Su family had no way of determining which one he chose.

Then the most likely solution would be tofu milk, but tofu milk doesn't have poison.

Song Yao thought for a while and asked Young Master Li's servant: "Besides eating tofu milk and buns, does Young Master Li have the habit of eating other things for breakfast?"

The maidservant shook her head: "For the past month, my young master has been obsessed with leonine's steamed buns. This tofu milk is his favorite food, no matter what he wants to eat, we will eat it together.

Song Yao nodded her head: "I understand, does that mean that the poison is not in the food anymore?"

Gongsun Xiao walked over to her side and asked: "What do you think?"

Song Yao shook her head: "I don't have any thoughts, there's no poison in the food, and he only ate this. Where is the poison, and how did he get poisoned?"

When the maid saw the situation, she whispered, "Our young master has recently offended quite a few people. Could it be …"

Song Yao asked: You offended someone? Where did you offend someone from? "

The maid replied in a helpless tone: "There are too many for me to count. Could it be that someone is seeking revenge?"

"I know he has committed many evil deeds, but why has he recently offended a lot of people?"

The maid sighed and said, "A while ago, young master was sick. He was in bed for a long time and couldn't get up, so it was quiet for a while. After Master did all he could to save him, and after he recovered, he started to go out again and go against the laws of the world, and offended who knows how many people. "

Hearing the maid's words, Song Yao clicked her tongue and said, "He doesn't treat you well either, right?"

"Ah?" She hurriedly asked, "Why do you say that, miss?"

Song Yao patted her shoulder and said, "Because I can hear your complaints and anger from your tone. You hate him for doing this right?"

The maid went silent for a moment, then said: "There's no need to complain or be angry, after all I'm here to serve young master and have a meal, I'm just a little sad for the people who are being bullied, especially for leonine, a good lady, a nice person with a kind heart, it's fine if young master really likes her, but you're always teasing me, causing me to have a good temper, I was so angry from young master."

Song Yao was silent, but the maid continued: "But anyone would get angry, right? leonine really can't take it anymore, that's why …"

Song Yao paused for a moment before asking, "Do you think the leonine has a motive to kill your young master?"

The maid hurriedly replied: "No, no, that's not necessary. Since there is no poison in the steamed bun, it must have nothing to do with leonine. I am just angry at what Sir has done to leonine."

Gongsun Xiao stood at the side and listened for a long time before saying: "Since there are some grudges, then these people are suspected, send a few people to investigate these people, where did they do at the time of the crime, and any contact with Young Noble Li before the murder, when, and where are you checking to see if there are any records of people buying medicinal herbs recently."

After the Prefecture Overseer heard Gongsun Xiao's words, he nodded his head and said, "This official will immediately send someone to settle this matter."

Gongsun Xiao nodded and said: "If that's the case, then I'll have to trouble Prefecture Overseer."

"Your Lordship is being too polite, this is what this official should have done." He turned and walked out of the room.

"What do you think?" Song Yao asked Gongsun Xiao.

Gongsun Xiao said: "This case is not that simple, I think we won't be able to find out for a while."
