Jingwen followed the palace maid to the front of the palace and met the official of Chang'an Mansion. He claimed to have found some clues about the palace maid, so Jing Wen naturally wanted to come over immediately. After that, the officer took out a painting and showed it to Jingwen.

"My lord, this is a painting on the body of that palace maid. The painting had already been swallowed by her, but we asked us to restore it by hand! Said quickly.

Jingwen couldn't help but feel a little sick when he heard that it was swallowed into his stomach. But since this painting is not the original painting, it has been restored by a master, then Jingwen can also be seen.

"Who is this man?" Jingwen asked.

The painting inside the belly of this palace maid depicts a man, about thirty years old. This man is still fair-eyed, and it is obvious that a fairly handsome person should be able to attract many ignorant girls. And is this palace maid trying to elope? However, even if he is not the lover of this palace maid, he should be a very important person, otherwise he would not have painted one of his paintings. However, why was it swallowed into the stomach, this is a little unclear? Is it love? Is it hate? No way to know.

"It seems that we must first find this man!" Jingwen said.

"There is a vast sea of people, where are we going to find it!" The officer of Chang'an Mansion said.

"Huh? I look like I've seen this guy! A eunuch said.

"Where have you seen that?" Jingwen immediately asked excitedly.

This person is the eunuch at the gate of the palace who is responsible for leading the horses for the officials who come to the court, and he actually knows this person.

"Isn't this the butler of Du Fu's shooting?" He said.

"Du Ruhui's housekeeper? Oops, how did I not think of it? Not good! Come with me to Du Ruhan's house! Jingwen said.

Jingwen thought of an important question, that is, it has only been less than twenty hours since the crime. From the time the case occurred to the time Jingwen entered the palace for investigation, it was only two or three hours. At that time, Li Shimin asked everyone to keep it a secret, and those prime ministers should know the strictness of the matter and will not say anything. But why is the other party's speed still so fast? actually let the entire palace spread the news that Empress Changsun had poisoned and murdered Du Ruhui? It's so fast, it's almost incredible. Moreover, in the case of extreme secrecy, those prime ministers will not talk casually to their families.

However, Du Ruhui, as a party concerned, naturally wants to talk to his cronies. And to be able to gain Du Ruhui's trust, in addition to his family, that is, his housekeeper. The housekeeper can be said to be the person who a person trusts the most, so there is nothing wrong with Du Ruhui telling the housekeeper the news of his poisoning. However, I'm afraid Du Ruhui doesn't know at all. This housekeeper is the real black hand of the matter, that is, he gave Du Ruhui the poison of the mandala, and wanted Du Ruhui to die of overdraft. When the time comes, no one will suspect that he, the housekeeper, is a murderer.

"Damn it, Infernal Affairs! Come with me, if you go late, I'm afraid Du Ruhui will be in danger! Jingwen said.

The housekeepers can be undercover, so I'm afraid that if you want to attack Du Ruhui next, I'm afraid it will be much easier. Now that the incident has occurred, it is difficult to guarantee that the other party will not do it directly.

"Papapapa......" Jingwen and Duguxin rushed to Du Ruhui's house with Qianniuwei.

"Bang bang bang!" "Open the door!" "Open the door!"

The matter is urgent. Jingwen didn't care about any etiquette, so he slammed the door hard.

"Who! It's so late, who came to us. Don't you know that this is Du Xiangye's mansion? When the time comes, I will offend Du Xiangye. You're all going to have bad luck! The mouth full of people scolded and opened the door.

"I don't have time to talk nonsense with you, we are on the orders of the emperor and come to find your housekeeper!" Jingwen said.

"The Emperor's order?" The servant asked, somewhat surprised.

"Less nonsense, what about your housekeeper?" Jingwen asked.

"The housekeeper is serving Xiangye for supper!" The servant said.

"What? Having a late-night snack? Where are you guys? Jingwen said angrily.

"It's in the bedroom. It's just three walls away! The servant said.

Jingwen immediately said to Dugu Xin: "Dugu Xin, hurry up and stop Du Ruhui, don't let him eat supper." I'm afraid there's a problem with late-night supper! ”

"Okay!"

Dugu Xin quickly used her light as a swallow martial arts to step on the protrusions of the wall and quickly climbed up the wall, and then ran quickly towards Du Ruhui's bedroom from the connecting wall on the wall again.

In the bedroom, the housekeeper was preparing to feed Du Ruhui for supper.

"Xiangye, this is a supper every day. Eat it! The butler said.

Du Ruhui didn't have any other suspicions, just picked up the small bowl, and the soup spoon was ready to drink.

"Whoosh!"

There was a sound that pierced the air, and a Hidden Arrow flew over.

"Smack!" The bowl in Du Ruhui's hand flew out.

And Du Ruhui saw the side where the dishes flew away, and then found that the soup bowl had smashed on a piece of silver paperweight, and the paperweight made of silver turned black.

"Poisonous?" Du Ruhui said.

The butler saw the situation and knew immediately that he had been discovered.

"Boom!"

Du Ruhui's housekeeper immediately ran away from the window at the other end of the room, and Duguxin didn't catch it.

"Damn, that's fast!" Duguxin scolded secretly.

Duguxin hurried to chase after him.

And Jingwen also took Qianniuwei to Du Ruhui's bedroom at this time.

"Du Xiang, are you okay?" Jingwen asked.

"It's okay, what's going on?" Du Ruhui asked.

Jingwen immediately said: "We found out that there is a problem with your housekeeper, so come over immediately." This poisoning is most likely the hand of your housekeeper! You see, this bowl of supper just now may contain highly toxic arsenic! ”

Jingwen's knowledge of chemistry has not been completely returned to the teacher, so he knows that arsenic in ancient times is actually sulfur-contained, so it will change color when it encounters silver. So, there should have been arsenic in the soup that night.

"My housekeeper? How is this possible? He has been with me for a few years, and since the Xuanwumen Change, he has followed me! Over the past few years, I have been loyal and there is no problem! But he wants to poison me? Du Ruhui still said unconvinced.

"Du Xiang, you have fallen into Infernal Affairs! This butler is a mole! Jingwen said.

"Hey, I don't know anyone, and I almost fell for it! That girl went to chase that guy just now, I don't know if I caught it! Du Ruhui said.

And at this time, Dugu Xin came back and said, "I'm not familiar with the environment of Du Xiang's mansion, so I chased it away!" ”

This housekeeper has been in this Du Ruhui's house for several years, so he is naturally familiar with the road. And he and Dugu Xin's light skills are similar, and Dugu Xin does not have an advantage. So, in this case, the housekeeper who is familiar with the environment naturally has a great advantage.

"Du Xiang, can you let Qianniuwei search here?" Jingwen asked.

"Please!" Du Ruhui agreed. (To be continued......)
