Li Tingbiao, who was entrusted with the important task, took over the torture duties of Gong Zhengsi with a heavy heart, but he did not continue to torture, but conducted detailed questioning of everyone.

Li Tingbiao first asked Wu Zhong and other eunuchs and maids of Zhongcui Palace what the Crown Prince had eaten recently and what he had been exposed to. Wu Zhong and others followed His Highness almost all day long. The most important thing was to check them first.

.

As the eunuch in charge of Zhongcui Palace, Wu Zhong felt that the sky was about to collapse. He cried and said: "I have been banned from reading in Zhongcui Palace. Only six of us slaves are waiting beside me. Half an hour ago,

Shortly after the young master had finished his meal, the Queen summoned the young master and left him to talk to him in Kunning Palace."

Li Tingbiao nodded and asked: "Did your Highness eat anything in Kunning Palace? What did you drink?"

Wu Zhong said with a tearful voice: "I ate roasted sweet potatoes and chestnuts with the Queen in Kunning Palace, but didn't drink anything."

Li Tingbiao continued: "Roasted sweet potatoes? Did the Queen also eat them? Did Your Highness test the poison before eating them?"

Wu Zhong said: "The Queen's portion was tasted by Zhang Gongzheng of Kunning Palace, and His Highness's portion was tasted by our family."

"What about after eating? What is His Highness doing? Has anyone contacted you?" Li Tingbiao said thoughtfully.

Wu Zhong replied: "They were chatting while eating. His Highness had a good appetite and ate two roasted sweet potatoes. He returned to Zhongcui Palace not long after eating."

Li Tingbiao was depressed. Zhang Gongzheng tasted it and was fine. The empress was fine after eating it. The crown prince was poisoned when he came back. How did he get poisoned?

He added: "What did your Highness eat after you came back?"

Wu Zhong said: "His Royal Highness only ate three boiled eggs after he came back, and nothing else. We tasted a small piece of each egg. There is nothing wrong with our family."

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

Who wanted to harm the crown prince? What method was used to harm him? Tens of thousands of thoughts were flying in Li Tingbiao's mind.

Li Tingbiao thought for a long time and then asked: "You just said that His Highness had a meal before going to Zhongcui Palace. What did His Highness eat?"

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

Li Tingbiao nodded, imprisoned Wu Zhong separately from the others, and then asked another eunuch of Zhongcui Palace, Qiu Zhizhong, and the four maids of Qin, Qi, Shu and Hua. The answers from several people were consistent with Wu Zhong's.

Judging from Li Tingbiao's many years of interrogation experience, the people in Zhongcuigong did not lie, and judging from their expressions and performance, it could not be them.

Then, Li Tingbiao questioned the Shangshan Supervisor, some eunuchs of the Inner Palace Supervisor, and even the eunuchs of the Si Li Supervisor for interrogation. In the end, nothing was gained.

Subsequently, Li Tingbiao led a large number of royal guards to conduct a large-scale search of Zhongcui Palace, Shangshan Supervisor and Inner Palace Supervisor. Not even a brick was missed, but there was still no clue.

After dark, the Forbidden City was closed, and Li Tingbiao returned to the mansion. He racked his brains along the way but could not figure out how the crown prince was poisoned.

As soon as he returned to the mansion, Li Tingbiao's mother-in-law began to nag: "I see you busy every day, but you also find a good job for your son. My father is the commander of the third rank of the Imperial Guard, but my son is still a subordinate."

Seventh-grade Xiaoqi, how embarrassing it would be to say this!"

Li Tingbiao glanced at his eldest son who was still practicing martial arts in the courtyard at night, and said calmly: "Did that boy complain?"

Mrs. Li frowned and said: "My son is a boring gourd like you. I would like him to complain. He is already twenty years old and has not even married a daughter-in-law. If you promote him to become a householder, I guess we

I’ll be able to have my grandson next year!”

Li Tingbiao hummed and said, "Don't worry about him. I haven't eaten for a day. Let's get someone to cook!"

Seeing his attitude, Mrs. Li raised her eyebrows. She took out two sweet potatoes from a bamboo basket in the courtyard and threw them in front of him. She said with an angry look: "The housekeeper just bought them from the street today. You can eat them raw yourself!"

Li Tingbiao ignored the aggressive attitude of his wife, but bent down to pick up the sweet potatoes on the ground, thoughtfully.

Seeing that her master was silent, Mrs. Li thought he was angry, so she suddenly became gentle and whispered: "Master, I am joking with you, don't take it seriously, I will let someone do it for you."

Li Tingbiao nodded coldly and said: "Do you have beef, chestnuts and eggs at home? Make some, I want to eat them!"

Mrs. Li wondered: "There are beef and eggs, but chestnuts probably aren't."

Li Tingbiao said to his eldest son who was practicing martial arts in the courtyard: "Li Hu! Go buy some chestnuts from the street and bring them back!"

"Dad! There is a curfew now and the market has been closed long ago!" Li Hu's voice came from the courtyard.

Li Tingbiao snorted coldly: "Don't you know how to use your brain? Take your Jinyiwei waist badge!"

Li Tingbiao was a little disappointed with his eldest son. He practiced martial arts every day and had no brains. He was such an old man and couldn't even hook up with a girl. How could he feel confident about promoting him?

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

Li Tingbiao looked at the four dishes in front of him thoughtfully. After thinking for a moment, he began to imitate the prince's meal sequence according to the order described by Wu Zhong during the day.

A quarter of an hour later, he ate it in order, but felt that there was no problem.

"Am I overthinking it?" Li Tingbiao frowned, looking at the remaining food on the plate, he ate the four dishes in order again.

After finishing the four courses of food, Li Tingbiao burped and felt a little stuffed. He was half-lying on the chair still thinking about the details of the interrogation during the day.

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

The servant who came to clean up the dishes was shocked when he saw the master like this, and quickly called for his wife.

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

Li Tingbiao quickly stopped her: "Don't look for the doctor, I'm fine! You all get out!"

After his family left, Li Tingbiao suppressed his nausea and vomiting and said to himself: "Your Highness, you are not only cruel to yourself, but you are also very good at acting!"

Li Tingxuan now fully understood that these four foods should be in conflict with each other. The empress was fine after eating roasted sweet potatoes and chestnuts, which means that the problem occurred in beef and eggs, which were in conflict with the previous two foods. Although Wu Zhong was both

He ate it, but he only took a small bite.

Finally, Li Tingbiao learned the conclusion: the crown prince took advantage of the food's mutual restraint to cause himself to have symptoms of being poisoned, and only a large amount of food would have the effect.

It's just that he doesn't understand. The medical skills of the imperial hospital are too poor. Why didn't anyone find anything? Could it be that the hospital envoy of the imperial hospital was bribed by His Highness?
