Doctor Xu said slowly, "The guards present told me that General Qian only had 50 breaths from poison to death, and the antidote pill was poured in the middle of the way and did not take effect. The military doctor had just arrived, and General Qian was already exhausted. ”

"Have you tested it, is it a red star cantharid?"

"Yes. Doctor Xu obviously did not intend to change his diagnosis, "General Qian was poisoned after dinner, and I checked his bowls, plates, chopsticks and leftover food with the military doctor, all of which were non-toxic." Later—" he paused, "and then I went to the stomach and found no toxicity." And General Qian's symptoms are also consistent with the poisonous attack of Red Star Cantharid, so it is basically determined. ”

"And this poison is still used by General Qian himself. The military doctor told me that General Qian had an old disease in his back that was difficult to heal, and he was miserable until the cold attack in autumn and winter. A master prescribed him a pair of medicines, and every time he had an old illness, he applied it to his waist, and the pain was immediately reduced. Red star cantharids are used in this recipe, and the dose is still very large. This substance is extremely effective in repelling cold and poison. ”

"I heard that he has been taking the medicine according to the prescription for more than five years, and he has applied it more than 100 times, how can he suddenly be poisoned?"

"Although the red star cantharidus is vicious, as long as the skin is intact and there are no tears, its poison will not seep in. Dr. Xu replied, "On the other hand, if there is a wound on the skin, it will enter the bloodstream and harm people." As far as the military doctor said, General Qian is also aware of this taboo, and he has always been careful with the use of medicine, and if he wants to go to the front line, he must first tear off the medicine patch. ”

Han Zhao rubbed his eyebrows: "Is there any injury on his body?"

"The arm was cut by a broken porcelain piece, but I am afraid that it was caused by the poisoning struggle, and it was not the cause. ”

Han Zhao nodded: "I'm afraid it's not caused by long-term drug accumulation." This toxin is too fierce to penetrate the human body at all, otherwise it will be a violent death. ”

"That's exactly what it is, the Red Star Cantharids will only make people die violently, and will never cause chronic poisoning, it turns out that Hou Ye also has research on toxicology!" Doctor Xu slapped him, but Han Zhao shook his head, "I don't know medicine or poison, I just know the masters." Still? ”

Dr. Xu hesitated: "The diagnosis after the incident is the above." However, the villain has never been able to let go of this case for dozens of days, so he flipped through the medical books and speculated on the possibility. Apparently unsure, he said dryly, "Yes, it's just possible." ”

Han Zhao was a little surprised: "Say it." ”

The villain saw in the miscellaneous notes that the medicine farmer caught the red star cantharid, and liked to use a fierce rooster about two years old. Chickens are the nemesis of a hundred insects, but they are the most poisonous after death. The Red Star Cantharid is aggressive, and even live chickens can fight. Doctor Xu coughed lightly, "Thinking back to the food tested that day, General Qian ate a whole roast chicken." ”

"Eating chicken will cause a canthalid poison attack?" Han Zhaoli felt that something was wrong, "Could it be that General Qian himself doesn't know?" Qian Ding's medication is not a day or two, and he must be very aware of the taboos of this drug.

"Just eat chicken, and you'll be fine. Dr. Xu shook his head, "I brought food back that day, and I found a spice from it, called boiling grass." This thing is hot and dry, and the whole plant must be red and sweaty after eating. Boiling the rooster with boiling grass will make it more yang, which will trigger the cantharidic poison fighting nature, which will change from hidden poison to obvious poison, and quickly penetrate into the skin. ”

When Dr. Xu said this, he paused slightly: "But I have inquired, boiling grass is often added to winter cooking in the army to expel the cold for the soldiers." "Otherwise, the cold night will be long, and the camp will not be as warm as the house. How can a soldier maintain his combat effectiveness after being frozen for a long time?

"When I got back to the city, I tested them on the rabbit, and sure enough, it didn't survive a few breaths before it died. ”

When Han Zhao heard this, he immediately ordered someone to bring the cook.

In the army, they all use men to cook big pot rice, but the meals of senior generals are still managed by special cooks, and small stoves are usually opened. This cook is also unlucky, Qian will die violently, he is the first to be suspected. After rounds of interrogation and torture, the fat man almost lost weight in a month.

Han Zhao came to him and only asked about the boiling grass and braised chicken.

The cook confessed that in the afternoon of that day, he had chosen a little tender hen to cook. But the chicken suddenly flew away, and he couldn't catch it, so the cook had to kill another rooster instead.

As for the boiling grass, it is indeed a spice that was purchased just a few days before the incident. At that time, it was just winter, and the temperature dropped too quickly, so it was often used in the army to cook to ward off the cold.

This is the third order given by Han Zhao: "Get the people who procure." ”

"Can't find it. Without waiting for the soldiers to go out to give orders, the cook smiled bitterly, "In the battle last month, the kid in charge of purchasing was shot dead by an arrow." ”

Han Zhao's eyes condensed slightly, and he waved his hand to make them all retreat.

The henchman behind him whispered: "Master Hou, is this just an accident?" It's not unusual to buy back the boiling grass, and it's not unusual for the chicken to be killed to fly away. Of course, the cook didn't know the prescriptions and taboos used by Qian Ding, so he boiled the rooster with boiling grass, and Qian Ding ate it, but at that time he was coated with ointment, and he died of poison......

"Every step is just right, and there are no doubts. Han Zhao said coldly, "Is this an accident?"

Sort of. If it didn't happen just right, how could it be called an "accident"? Of course, the henchman couldn't say this, so he had to say: "What does Master Hou mean, and continue to track down the murderer?"

"Of course. Han Zhao swept his gaze outward, "The murderer is hidden in the dark, he won't just strike once." ”

He suddenly sighed softly: "If it is really man-made, such a method of leaving no traces is very similar to an old man I recognize." ”

The henchman was about to speak, when there was a sudden commotion outside, mixed with shouts and reprimands.

As soon as Han Zhao's brows furrowed, someone came in to report: "There is a father-in-law outside, saying that he is a prison sent by the royal capital!"

Overseer?

Han Zhao stood up and strode out.

Sure enough, there was a group of people standing outside the barracks, led by a man over forty years old, lean, white-faced, and behind him stood guards in bright armor, all of whom were expressionless.

When he saw Han Zhao, he immediately laughed: "Master Hou, it's not easy for you to enter this barracks." With that, he shook the red gold order in his hand.

This is a special order of supervisors given by Wei Ting, with which the supervising army can come to assist in military affairs on behalf of the royal court, and of course, the most important function is to supervise the generals.

However, the soldiers of the Marquis of Zhenbei only recognized the tiger talisman of the general, not the order of the supervisor.

"A few guards of the gate, can you know what the sky is high and the earth is thick?" Han Zhao waved his hand, and he didn't care, "Father-in-law Tai is here, and he is not welcomed." Come on, please come in!"

Wang Du came to the news, and he had already mentioned that King Wei sent the great eunuch Tai Gonggong around him to come and wait for the army. Han Zhao just didn't expect the other party to come so quickly.
