This question is actually a very simple logical reasoning question. Only one of the four people is telling the truth. If A is telling the truth, then A is not the criminal, and B, C, and D are all lying. B's lie means D is not the criminal, C's lie means B is not the criminal, and D's lie means B is telling the truth, which means D is the criminal, which creates a contradiction. So we can conclude that A is not telling the truth, so A is the criminal.

This question is not a difficult question for modern people, but it is still a bit difficult for these ancient people who have not learned logical reasoning to do this question. Although An Zicheng's literary talent is not as good as others, he has a quick mind. In addition, he writes novels on weekdays, so Lu Zheng thinks this question should not be difficult for him.

After one stick of incense, only a few people handed in their papers. Lu Zheng graded them on the spot. Except for a few who wrote randomly and some who simply guessed the answers. Lu Zheng promised that there would be more recruitment like this in the future, and the excited scholars left with satisfaction.

In the end, only five people answered correctly, which was the same as the number of people who entered the interview as stated in his notice. Fortunately, An Zicheng lived up to everyone's expectations and answered correctly, otherwise Lu Zheng would have to worry about how to squeeze him into the interview.

Among these five people, the one who answered the best was not An Zicheng, but a scholar named Gu Xiang, who was the Linxian scholar who had stared at Bao Zheng at the registration office before. According to him, he had always admired Lu Zheng, so when he heard that Lu Zheng was recruiting clerks, he immediately hired a carriage and ran over. It

was the first time that Lu Zheng faced his fanboy directly. In addition to embarrassment, he was inevitably a little proud, but in front of everyone, he could only say with a straight face: "After lunch, the five of you will have an interview in turn."

Lu Zheng did not intend to make it too formal, and held the interview in the reception hall of the back yamen.

This examination method was too novel, and everyone was a little trembling. The first person to come in was a scholar from the county.

As soon as he came in, he bowed and said, "Student Cheng Kai has met Lord Lu."

Lu Zheng waved his hand and said, "Mr. Cheng, don't be too nervous, sit down first."

Cheng Kai quickly said, "How can a student sit in front of a master? This is not proper."

"It's okay, you sit down."

Cheng Kai sat down hesitantly.

Although Lu Zheng had never been an interviewer, he couldn't help frowning when he saw Cheng Kai's behavior. If he really planned to recruit employees through open recruitment, Cheng Kai's timid and petty nature would be rejected by him at the first time.

After Cheng Kai sat down, Lu Zheng said, "The first question of the interview is: If I give you and Bao Zheng a job, but Bao Zheng, relying on his seniority, interferes with your work and causes the job to fail, what will you do?"

This question should be considered a question about interpersonal relationships in modern civil servant interviews, and it is a relatively basic question. Modern times already have a set of templates for answering, but in ancient times, this was still relatively new and happened to be used to test people's emotional intelligence. Sure enough, Cheng Kai was immediately speechless and could not answer.

When the interview time was over, Cheng Kai walked out with his head down and dejected. The scholars waiting for the interview outside turned pale. Some wanted to ask Cheng Kai about the content of the interview, but were scared back by Bao Zheng's heavy cough.

The second person to go in was Gu Xiang. He looked confident. After hearing the topic, he thought for a moment and then spoke eloquently: "Thank you for your kindness, sir. You have given me such an important task. As a newcomer, I should learn more and see more. Since Captain Bao is willing to teach me, I am very grateful. If I have not done well, it is also because I am inadequately learned. I will naturally apologize to you and listen to your advice with an open mind. I will study harder in the future to repay you."

Lu Zheng's eyes lit up. Gu Xiang's answer was already remarkable, not to mention that his attitude was so sincere. At least it showed that he had a high emotional intelligence. So Lu Zheng asked the second question: "There is a scoundrel named Zhang Sheng in this county. He bullies men and women and does all kinds of evil. One day, he extorted an old man and accidentally beat him to death. A righteous man passed by and killed Zhang Sheng in anger. The case was reported to the county government. If you were the official, how would you judge the case?"

This time, Gu Xiang thought for a while and finally answered: "Zhang Sheng killed people, which is unforgivable, but he has paid with his life, so the case can be closed. The righteous man killed people, which is pitiful, but the crime is hard to forgive. His righteous behavior should be rewarded, and his crime should be sentenced."

This is a question that contradicts legal principles and human feelings, but Gu Xiang divided the case into two parts, and his logic is clear, which is enough to show his talent in this area.

Lu Zheng felt a little regretful. He really admired Gu Xiang, but it was a pity that he was destined to have no way to keep this man this time. After Gu Xiang finished answering, two more scholars passed before it was An Zicheng's turn.

Since he had decided to hire An Zicheng, Lu Zheng did not plan to ask him any difficult questions. An Zicheng was a smart man. As soon as he heard Lu Zheng's question, he knew that there was something fishy about the so-called exam, but he pretended not to know and answered the questions smoothly.

Lu Zheng announced the results, and An Zicheng proudly bowed to everyone one by one. The others could not answer, so they could only leave with a sullen look. Only Gu Xiang looked a little disappointed.

Lu Zheng also felt very guilty towards him and wanted to go up to comfort him, but Gu Xiang came over and said to Lu Zheng sincerely: "I am not very good at learning, and I am convinced of this result. But I didn't bring enough when I came here, and now it is difficult to return home. I hope you can take me in temporarily, let me study with you, and wait for your orders."

Lu Zheng was stunned, and a term unconsciously emerged in his mind - temporary worker.

Gu Xiang didn't know that he had been assigned the identity of a scapegoat, and he still looked at Lu Zheng very persistently.

Lu Zheng felt guilty, and since he asked so, he naturally agreed.

Lu Zheng told An Zicheng the truth and asked him to keep it a secret. An Zicheng naturally agreed. He also knew that his identity was not legitimate, so he temporarily restrained his sloppy style and followed Gu Xiang to sort out the case files of previous years.

Lu Zheng used this trick to directly confuse the vision of the people watching behind him, making it difficult for people to see his intentions, but at this moment he was in a dilemma.

Now the case has come to a stalemate. If he wants to solve the case, he will have to meet Mrs. Lu, but Mrs. Lu's identity is very sensitive. Lu Zheng is also afraid that he will reveal any clues and be discovered. If he didn't solve the case, the case would be closed as Lu Enshan murdering his brother. Not to mention that murder is a serious crime, the elder brother is the father, and killing his brother is aggravated. Not only will Lu Enshan's life be in danger, but his wife, concubines and children will also be implicated, which Lu Zheng could not tolerate.

Lu Zheng thought about it and finally had to use the trick of procrastination. He believed that the person behind the scenes wanted to close the case as soon as possible more than he did. If they made any moves, they would naturally reveal their flaws. Only by knowing the identity of the person behind the scenes could he continue with the next thing.

Just when Lu Zheng was worried about these things, Rong Zhen, who was far away in the northern border, received the first secret letter sent from Nanxia County.

Rong Zhen tapped the table lightly. The letter said that the vicious Sea Dragon King was actually secretly controlled by the King of Wei. When Rong Zhen was in Jiangnan, he felt that the salt policy was not a simple matter. He openly punished corrupt officials with great fanfare, but secretly investigated and found that there seemed to be a mysterious force controlling the matter in secret.

Later, Rong Zhen also played along with the enemy, but he didn't expect that it would attract Liang Jue, which made him alert. If the opponent's power had penetrated so deeply, and they still knew nothing about the initiator, it would be dangerous. It was not

until the Jie people declared war, coupled with the news brought back by Song Zhiyi's investigation, that Rong Zhen finally confirmed that Wei Wang Rong You was not dead. Not only was he not dead, he had also used twenty years to weave a dense network in the Great Xia Dynasty.

After confirming this, Rong Zhen decisively changed his plan. The Jie soldiers suddenly felt that the opponent who was originally evenly matched had suddenly become extremely fierce and difficult to resist.

Su Yiwuya was originally ambitious to defeat the Northern Frontier Army and force Emperor Yongning to negotiate peace with him, but now he has to face the sudden and fierce attack of his opponent and is exhausted.

Now that the war is progressing smoothly, Rong Zhen can spare the time to care about the latest news found by Ye Xiao. When he saw the news from Nanxia County, he was reminded that Lu Zheng was the county lieutenant in Qingxi County. He just hoped that he would not get involved in these things. However, even if something happened, the few secret guards he left behind should be able to guarantee his safety.

Although he comforted himself in this way, Rong Zhen still called Nie Zhishu. Nie Zhishu was dressed in iron armor, with a scar on his cheek that had just healed, and his murderous aura seemed to suffocate people.

Nie Zhishu said directly: "If the master is asking about the traitor Xin Gangyi, I have already killed him! If you want to punish me, I will accept the punishment willingly."

Xin Gangyi was the leader of the Northern Frontier Night Owls who had betrayed them before. After Rong Zhen arrived in Northern Frontier, he quickly took the initiative in the war. Nie Zhishu hated Xin Gangyi for betraying his master and volunteered to hunt him down. Xin Gangyi escaped for a long time, but was finally caught by Nie Zhishu and beheaded.

Rong Zhen said: "Xin Gangyi's crime is unforgivable. Since he is dead, hang his head on the city wall to serve as a warning to others."

Nie Zhishu was puzzled. Although Rong Zhen was strict in military management, he never used the method of showing people heads. Now he didn't know why, but he still agreed.

Rong Zhen pondered for a while, then said calmly: "Go call Song Zhiyi and Su Dai, the chess pieces that were buried can be moved."

Nie Zhishu's eyes lit up: "Master, you mean..."

"Su Yiwuya has been making trouble for long enough, the Jie tribe should have someone else to take charge."
