Li Tingbiao, who was entrusted with the important task, took over the torture duties of Gong Zhengji with a heavy heart, but he did not continue to carry out the execution, but questioned everyone in detail.

Li Tingbiao first asked Wu Zhong and other eunuchs and palace maids of Zhongcui Palace, what the crown prince had eaten recently and what he had been exposed to, Wu Zhong and others followed His Royal Highness almost all day long, and it was most important to check them first.

As the steward eunuch of Zhongcui Palace, Wu Zhong felt that the sky was about to fall, and he said with tears: "The master is forbidden enough to come and read books in Zhongcui Palace all the time, only the six of us slaves and maids are waiting by his side, half an hour ago, not long after the master had a meal, the queen mother summoned the master, and left the master to talk in Kunning Palace. ”

Li Tingbiao nodded and asked, "What does Your Highness have to eat in Kunning Palace?" What to drink? ”

Wu Zhong said with a crying voice: "The young master ate roasted sweet potatoes and chestnuts with the queen mother in Kunning Palace, and did not drink anything. ”

Li Tingbiao continued: "Roasted sweet potatoes? Did the queen eat it too? Can Your Highness test the poison before eating? ”

Wu Zhong said: "The queen's share is tasted by Zhang Gongzheng of Kunning Palace, and His Royal Highness's share is tasted by our family." ”

"And what about after eating? What is His Highness doing? Has anyone touched it? Li Tingbiao said thoughtfully.

Wu Zhong replied: "They chatted while eating, His Royal Highness had a good appetite, and he ate two roasted sweet potatoes in a row, and returned to Zhongcui Palace not long after eating." ”

Li Tingbiao was depressed, Zhang Gongzheng tasted it, and the queen was fine after eating, but the crown prince was poisoned after he came back, how was he poisoned?

He said, "What did His Highness eat when he came back?" ”

Wu Zhong said: "After His Highness came back, he only ate three boiled eggs, and nothing else, and our family tasted a small piece of each egg, and our family didn't have anything to do." ”

Li Tingbiao saw Wu Zhong's lively appearance, and also knew that he was fine, which made him even more depressed, Wu Zhong had tasted everything that the crown prince had eaten, and there was no problem, but His Royal Highness was poisoned.......

Who wants to harm the crown prince? What method is used to inflict harm? Li Tingbiao has thousands of thoughts flying in his head.

Li Tingbiao thought for a long time, and then asked: "You just said that Your Highness had a meal before going to Zhongcui Palace, what did Your Highness eat?" ”

Wu Zhong thought for a moment and said, "Your Highness only ate one serving of beef and rice, and the other dishes were almost untouched. ”

Li Tingbiao nodded, separated Wu Zhong from the others, and asked Qiu Zhizhong, another eunuch of Zhongcui Palace, and the four palace maids of Qinqi, calligraphy and painting, and the answers of several people were the same as Wu Zhong.

Judging from Li Tingbiao's many years of interrogation experience, the people of Zhong Cui Palace did not lie, and judging from their expressions and performances, it would not be them.

Then, Li Tingbiao asked some eunuchs of Shangshan Prison and Inner Palace Supervisor in turn, and even the eunuchs who passed the decree of the celebrant were pulled over and interrogated, but in the end there was still no result.

Subsequently, Li Tingbiao led a large number of brocade guards to conduct a large-scale search of Zhong Cui Palace, Shangshan Prison and Inner Palace Supervisor, not even a single brick was spared, and there were still no clues.

After dark, the palace ban in the Forbidden City was opened, and Li Tingbiao returned to Fuzhong, racking his brains along the way and not thinking about how the crown prince was poisoned.

As soon as he returned to the house, Li Tingbiao's mother-in-law began to nag: "I see you busy every day, you also find a good job for your son, my father is the commander of Jinyiwei from the third grade, but his son is still a small flag from the seventh grade, how embarrassing it is to say it!" ”

Li Tingbiao glanced at his eldest son, who was still practicing martial arts in the courtyard after dark, and said lightly: "That kid complained? ”

Mrs. Li frowned and said: "My son is a stuffy gourd like you, I want him to complain, he is twenty years old, and he hasn't even married a daughter-in-law, if you promote him to a hundred households, it is estimated that we will be able to hold a grandson next year!" ”

Li Tingbiao snorted lightly: "You don't have to worry about him, I haven't eaten for a day, hurry up and let someone cook!" ”

Seeing his attitude, Mrs. Li raised her eyebrows, took out two sweet potatoes from a bamboo basket in the courtyard and threw them in front of him, and said, "The housekeeper just replaced it from the street today, you can eat it raw yourself!" ”

Li Tingbiao ignored his mother-in-law's spicy attitude, but bent down to pick up the sweet potatoes on the ground, thoughtful.

Seeing that her master was silent, Mrs. Li thought he was angry, and suddenly became soft-voiced: "Master, I'm joking with you, don't take it seriously, I'll let someone do it for you." ”

Li Tingbiao nodded coldly and said, "Do you have beef, chestnuts and eggs at home?" Go and do some and I want to eat! ”

Mrs. Li was puzzled: "There are beef and eggs, but there should be no chestnuts." ”

Li Tingbiao said to the eldest son who was practicing martial arts in the courtyard: "Li Hu! Go buy some chestnuts on the street and come back! ”

"Daddy! It's curfew, and the bazaar is long closed! Li Hu's voice came from the courtyard.

Li Tingbiao snorted coldly: "Don't you know how to use your brain? Grab your brocade guard waist card and go! ”

Li Tingbiao was a little disappointed in his eldest son, he practiced martial arts every day and didn't have a brain, such a big person, he couldn't even hook up with a girl, how could he let himself be relieved to promote him.

Two quarters of an hour later, in Li Tingbiao's study, four dishes were placed on the book, beef, chestnuts, roasted sweet potatoes, and boiled eggs.

Li Tingbiao looked at the four dishes of food in front of him, thoughtfully, and after thinking for a while, he began to simulate the order of the crown prince's meals in the order described by Wu Zhong during the day.

A quarter of an hour later, he ate them in order, but felt fine.

"Could it be that I'm thinking too much?" Li Tingbiao frowned, looked at the leftover on the plate, and ate the four dishes again in order.

After eating a full four-course meal, Li Tingbiao burped and felt a little overwhelmed, and he was still thinking about the details of the interrogation during the day in his half-reclining chair.

In less than a quarter of an hour, Li Tingbiao only felt nausea in his stomach, and then began to vomit.

The subordinates who came to clean up the dishes and chopsticks were startled when they saw the old man like this, and hurriedly found his wife.

Mrs. Li said nervously: "Master, what's wrong with you?" Don't scare me! Butler, go find Langzhong! ”

Li Tingbiao hurriedly stopped her: "Don't look for Langzhong, I'm fine!" You all get out! ”

After the family left, Li Tingbiao endured nausea and vomiting and said to himself: "Your Highness, you are not only cruel to yourself, but also very capable of acting!" ”

Li Tingxian fully understood that these four foods should be restrained, and the queen mother was fine if she ate roasted sweet potatoes and chestnuts, which means that the problem appeared in the beef and eggs, and the two foods in front of her were restrained, although Wu Zhong ate both, he only tasted a small bite.

In the end, Li Tingbiao learned that the crown prince had used this food to restrain himself and make himself have the symptoms of being poisoned, and it was only effective when he ate a large amount of food.

It's just that he doesn't understand a little, the imperial medical skills of this hospital are too inferior, why didn't anyone find anything? Could it be that the imperial envoy was bribed by His Highness?

It seems that we have to go to the envoy of the Tai Hospital, and it is better to deal with it thoroughly.
