Zhang Sanlang climbed on the roof and took a few tiles down, and sure enough, Di Renjie also found a few red dots on the tiles that were as red as blood!

"Sir, it's the perpendicular poison!" Li Yuanfang said suddenly!

"What is perpendicular poisoning?" Zhang Saburo asked!

"Vertical poisoning is a common assassination method used by professional killers on the rivers and lakes, mostly taking advantage of the fact that the victim is asleep, lying on the roof, and using a special silk thread to hang on the victim's mouth from top to bottom, and most of the people are slightly open when they are asleep, so the killer uses the silk thread as a guide to run the venom down, so that the poisoning is completed without the owner's knowledge!" Li Yuanfang explained!

"A professional killer again? How can our poor and remote Shiyi County attract so many killers? It's weird! Zhang Saburo said with emotion!

"Let's collect Lord Cai's body first! San Lang, does this Lord Cai have a family? Di Renjie asked!

"My grandfather has no children under his knees, only one daughter married a few years ago and went to other places, and last year my grandfather's wife died of illness, so this county government has no one else out of our class of servants!" Zhang Sanlang said with some sadness!

"Alas! It's a pity that a Qing official, diligent in serving the people, was alone when he died, pitiful! Send someone to send a message to Lord Cai's daughter! Di Renjie said with a sad expression!

"Alas! Not really! I don't know what kind of official he is again? He Da sighed on the side!

"San Lang, come with me!" Di Renjie walked out of Cai Wanquan's room and called Zhang Sanlang over!

Zhang Sanlang and Li Yuanfang followed Di Renjie to Di Renjie's resting room, Di Renjie raised his hand, Li Yuanfang immediately understood and closed the door!

"San Lang, can I trust you?" Di Renjie said suddenly!

Zhang Sanlang was stunned for a moment, and then said: "Mr. Huai, if you have any orders, just say it!" Saburo will live up to his promise! ”

"Good! Saburo, look at this? With that, Di Renjie handed a document to Zhang Sanlang!

Zhang Sanlang took the paperwork, and when he saw it, he was shocked, and hurriedly knelt down, "Zhang Sanlang, the head of the lowly Shiyi County team, knocked on the old Qincha Dige!" ”

"Hurry up! This is not the time to be polite! I'm really helpless this time, if it weren't for the murder of the court officials, I wouldn't have exposed my identity! Di Renjie helped Zhang Sanlang up!

"The little one is really eyeless, I have long heard that the imperial court sent a Qin cha, no wonder you have such a magic skill in solving cases, it turns out that you are the famous detective Di Ge Lao!" Zhang Sanlang hugged his fists and saluted respectfully!

"San Lang? Now that there is such a thing in the county government, I think there are probably people in the county who we don't know the identity, and now that Lord Cai has died, the county government can't be left without an owner for a day, so I will write a letter, you send someone to send 600 miles to the Shendu urgently, and hand it over to the prime minister Zhang Cambodia, I will ask the emperor to appoint you as the new county magistrate of Shiyi County! Di Renjie said softly!

"Thank you, Elder Ge!" Zhang Sanlang immediately knelt down to thank him, and was pulled up by Di Renjie again!

"This matter is confidential with my identity, don't disclose it to the outside world for the time being, now the top priority is to find out if there is an internal response of the gangsters in the county government, let's ...... like this next" Di Renjie suddenly lowered his voice and whispered in Zhang Sanlang's ear for a moment!

At noon that day, in the backyard of the county ya, the county ya's master, how big is it, the three classes of the ya, including the subordinates of the county ya's house, gathered here, Di Renjie, Li Yuanfang, and Mo Qingfeng were also invited!

"Everyone, the master unfortunately passed away, although the murderer is still at large at this time, but after Mr. Huai's investigation, important evidence was found at the scene of the murder, and it is now sealed in the master's room, from now on, the master's room is tightly sealed, and no one is allowed to enter! I have reported the matter of this county according to the truth, and a new grandfather will arrive in the near future, and this room can only be opened when the new grandfather arrives, and the sea fishing documents will be issued immediately according to this evidence! Zhang Sanlang said loudly in front of people!

"Yes!"

Everyone dispersed, and the room where Cai Wanquan originally lived was affixed with the seal of Shiyi County, and there were two officials outside the door who were in charge of guarding it!

After settling everything, Zhang Sanlang came to Shiyi Post Station with Di Renjie's letter, and Yicheng learned that the letter was addressed to the prime minister of the dynasty, so he naturally did not dare to slack off, and immediately ordered the post guard to ride a fast horse to send the letter to Shendu!

In Di Renjie's room, Li Yuanfang and Mo Qingfeng were eating with Di Renjie!

"Sir, I heard that this Cai County Order was poisoned to death, what kind of poison did he have?" Mo Qingfeng asked!

"This poison is quite rare, and I didn't know about it!" Di Renjie replied!

"Oh, I didn't expect this kind of thing to happen in the county government of the imperial court, these gangsters are really bold!" Mo Qingfeng said indignantly!

"Yes! Who would have thought that a county magistrate would be poisoned in the county government, this murderer is really crazy! Li Yuanfang echoed!

"Didn't Zhang Saburo say that he had found the evidence left by the murderer? I guess it must be the work of the gentleman, right? Mo Qingfeng asked with a smile!

Di Renjie smiled and said nothing, eating by himself!

"Sir, what is the evidence you found for them?" Mo Qingfeng lowered his voice and asked curiously!

"Don't say! I can't say it! Di Renjie pretended to be mysterious and said!

Two days later, in the night, the prime minister Zhang Cambodia in Shendu received a letter from Shiyi County.

"Come on, hurry up and prepare the car, I want to enter the palace to face the saint!" Zhang Cambodia said excitedly!

The people were quite surprised that the elder of the pavilion, who had been frowning for several days, actually became happy and smiling after reading a letter!

Wu Zetian was already preparing to rest in the palace at this time, and suddenly the chamberlain came to report, "Your Majesty! Lord Zhang Cambodia asks to see! ”

"Huh? This Zhang Cambodia, what can't I talk about tomorrow? Wu Zetian was a little displeased!

"Then Your Majesty, I'll go back to him?" The chamberlain asked tentatively!

"Forget it, let him in, come in at night, there should be something urgent!" Wu Zetian said!

After a while, Prime Minister Zhang Cambodia trotted all the way, and as soon as he entered the hall, he immediately leaned down and bowed down!

"Weichen Zhang Cambodia knocks to see Your Majesty, long live, long live, long live!" Zhang Cambodia's respectful salute!

"Cambodia is flat, enter the palace late at night, what is the matter?" Wu Zetian asked coldly!

"Your Majesty, great joy! Elder Di Ge has a letter! Zhang Cambodia said excitedly!

"What? Huaiying sent a letter? That proves that Huaiying is still alive? Wu Zetian was suddenly overjoyed and stood up excitedly!

"Yes! Di Ge Lao is indeed safe and sound! "The way of Zhang Cambodia!

"Good! Good! Good! Wherever the letter is, quickly present it to me! Wu Zetian couldn't hide the excitement in his heart for a while!

Zhang Cambodia presented the letter, and the chamberlain took it and presented it to Wu Zetian!

After a while, Wu Zetian finished reading the letter, and his face was still sinking like water just now, and at this moment, the gloomy clouds dissipated, and he was overjoyed!

"Cambodia, you immediately draft the will, and I will follow what Huaiying has done one by one!" Wu Zetian said excitedly!

"Wechen obeys!" Zhang Cambodia's gift responded!
