Just when Cao Shuang was at a loss, the news that Cao Zhen brought to Cao Shuang made him even more depressed. It turned out that when discussing in the Prime Minister's Mansion today, Wei Zhen proposed to transfer the Wei Tong murder case to Dali Temple for trial. This is undoubtedly worse for Cao Shuang, and when the case arrives in Dali Temple, there is no room for maneuver. Cao Shuang sat on the recliner, looking at the moon in the sky, and unconsciously touched the side of his thigh, trying to find a cigarette. After touching it for a moment, he smiled self-deprecatingly, and he forgot that there were no cigarettes here.

When he was young, Cao Shuang was already asleep, only to hear a squeak, and the window was opened. Cao Shuang woke up in a dream and saw that the oil lamp on the table did not burn a blue flame, so his hand quickly touched the dagger under the pillow. When he saw the black shadow standing not far away, Cao Shuang breathed a sigh of relief, it turned out to be Li Pet.

"Big brother, I don't sleep in the middle of the night, what are you doing in my room, you want to scare me to death!" Cao Shuang said in a low voice, let go of the dagger in his hand, and sat up with his clothes on.

Li Pet smiled embarrassedly and arched his hand to Cao Shuang, "Son, forgive me, there is really an urgent matter that needs to be reported!" ”

"Say it!" Cao Shuang waved his hand, rubbed his eyes and said.

"Li Jue may have other people involved in this matter." Li Pet put the oil lamp on the table, and then said, "A few days ago, when Gongzi and Li Jue went to the Wei Mansion to apologize, one of them had been watching not far away, and then I secretly followed. In the past few days, I have been monitoring him, and last night he went to Wei Mansion in person, and then today Wei Zhen played the murder case to Dali Temple. ”

After listening to Li Chong's words, Cao Shuang was completely sleepy, and asked anxiously, "Who is it?" "The body is not afraid of the shadow, but it can't stand someone framing behind the ground.

"Sima Shi, the eldest son of Sima Yi, the head of the Prime Minister's Mansion!" Li Pet stepped forward and took two steps, almost sticking it to Cao Shuang's ear and said. In the past few days, Li Pet has not returned to Cao's Mansion, and Cao Shuang is also used to this situation, but he didn't expect Li Pet to bring back such exciting news this time.

Cao Shuang nodded, and then waved his hand to let Li Pet go back to rest. Cao Shuang looked at the oil lamp in front of him and fell into deep thought, in the past few years, Cao Shuang and Sima Yi have nothing to do with it, and he didn't even say a few words, why did Sima Shi suddenly participate in this matter. With intuition, Cao Shuang knew that Wei Tong's death was absolutely inseparable from Sima Shi.

On the second day, as soon as Huangfu Li came back from going out to collect medicine, he was invited to the Xuchang Mansion by Cao Shuang. In the place where the body was stored underground, Huangfu Li saw Wei Tong's body. On the way here, Yuan Lie had already explained the ins and outs of the matter to Huangfu Li, and this time he invited the old man to go to let him see what poison Wei Tong died under.

Through the faint light of the oil lamp, Huangfu Licha carefully examined Wei Tong's corpse. Half an hour passed, Huangfu Li stood up straight and beat his sore waist, "Poisoned, suddenly out of breath." ”

"Old man, do you know what poison in Wei Tong?" Cao Shuang's face was full of anxiety, and he asked in a hoarse voice.

Huangfu Li pulled out the silver needle inserted in Wei Tong's heart, put it under his nose and sniffed it gently, and said with certainty, "This is Tianjin Grass!" ”

Hearing Tianjincao, Cao Shuang was very surprised, but quickly calmed down. On that day, Cao Jun stationed in Chang'an was hit by the numb tendons of the Red Fire Dao people, and it was Huangfu Li who used Tianjin Grass to detoxify, which saved Cao Jun. Tianjin grass and hemp tendon grass are born together, and the two are mutually reinforcing. If the two grasses are used separately, they are both highly poisonous. The toxicity of Tianjin grass is very weak, and it will corrode the internal organs little by little, and there is no cure except for hemp tendon grass. The poison of Tianjin grass is a long process, generally between three months and six months according to the physical fitness of the poisoned person, but when mixed with alcohol, it will cause people to suddenly lose their breathing, that is, cardiac arrest.

Along the way, everyone was speechless. It wasn't until in the private room of the teahouse that Cao Shuang spoke, "After the detoxification that day, the hemp tendon grass and the heavenly gold grass were handed over to the imperial doctor." "During the Eastern Han Dynasty, there were two main types of division of labor within the Taichang Taiyi Order: the Taiyi who was responsible for diagnosing and treating diseases, and the Yaofu who presided over the prescription of medicines. The Imperial Physician was not only responsible for the diagnosis and treatment of diseases of the central officials, but also in charge of medical matters in the local counties. At that time, each county had a chief physician who was responsible for the imperial physician. In the Yaofu system, the chief medicine officer presides over the medical affairs and the medicine is stored by the Yaozangfu. In addition to Yao Cheng and Fang Cheng, under the Taiyi Cheng, there is also a Tai Yi Supervisor. Below, there are doctors and clerks.

Huangfu Li stroked the beard under his chin and shook his head, "It can't be ruled out that there are people who know about hemp tendon grass and Tianjin grass among the people, and it can't be ruled out that some people still have these two herbs. ”

"Impossible!" Cao Shuang shook his head very firmly. Others don't know, but Cao Shuang knows very well that since he knew the power of the hemp tendon grass, Cao Cao had ordered to look for the hemp tendon grass and the Tianjin grass in various places. It is impossible for the people to hold the hemp tendon grass and the heavenly gold grass, and all the hemp tendon grass and the heavenly gold grass are concentrated in the central medicine house.

"Then the scope of this matter will be greatly reduced." Huangfu Li took a sip of tea and said.

Cao Shuang nodded thoughtfully and contacted Sima Shi. With a keen sense of smell, Cao Shuang seemed to smell the smell of conspiracy.

Sima Yi was the head of the Prime Minister's Mansion at the time, and some things were done through him, and things like hemp tendons and grass would be recorded very clearly in the documents. The main bookkeeper is a typical civil official, pawning documents and handling affairs, which is roughly equivalent to the current secretary-general. Then Sima Yi will not be able to escape from this matter. Cao Shuang secretly planned in his heart, but he couldn't easily move Sima Yi. His background is complicated, Sima Yi's great-grandfather Sima Jun was the general of the expedition to the west during the Han Emperor's reign, his great-grandfather Sima Liang was Yuzhang Taishou, his grandfather Sima Jun was Yingchuan Taishou, and his father Sima Fang was Jingzhaoyin. Sima Yi is in the prime minister's mansion, and he has a very good relationship with Cao Pi. Although on the surface, Sima Yi and Cao Pi have little relationship, but behind the scenes, Cao Shuang, who is in charge of the night detective, is clear.

Since Sima Yi can't move, then he can only start from the weak point, and the medicine house ordered by the imperial doctor is much simpler. Thinking of this, Cao Shuang had a long-lost smile on his face. Seeing Cao Shuang's smile, Yuan Lie's eyelids couldn't help jumping, the last time he was engaged in Zhang Song, he had seen Cao Shuang smile like this. I don't know who is going to suffer again this time, this Cao Gongzi has never played cards according to common sense. However, Yuan Lie can be regarded as breathing a sigh of relief, no matter who is unlucky and hits Cao Shuang's muzzle, at least things are developing in a good direction, Li Jue is saved this time.

Cao Shuang was in a good mood, so he asked the store to serve a few more plates of exquisite dim sum and eat it happily. While eating, I didn't forget to entertain Huangfu Li and Yuan Lie to eat together, these days, Cao Shuang has eaten very little, and when he was in a good mood, he suddenly felt very hungry. Looking at Cao Shuang's eating appearance, Huangfu Li and Yuan Lie looked at each other and smiled, and they were both relieved. The elegant eating appearance of the two, Cao Shuang formed a stark contrast.

Li Cong, who was standing on the side, coughed lightly to remind Cao Shuang to pay attention to his appearance. Cao Shuang looked up at Huangfu Li and Yuan Lie with a smirk, and then continued to eat, "Eat quickly!" Eat! The slag of the dim sum leaked out of Cao Shuang's mouth as Cao Shuang spoke.

In the single room of the teahouse, there were bursts of laughter.
