Please give a summary of the story of "Yang Naiwu and Xiao Baicai"

One day, the young and beautiful Xiao Baicai happened to meet Yang Naiwu in a restaurant, who was helping people write complaints. Yang Naiwu was immediately attracted by Xiao Baicai's beauty, and Xiao Baicai happened to rent the house of Yang Naiwu's family. . Yang Naiwu took pity on Xiao Baicai's life experience and asked her to help organize the new study and do chores to supplement the family income. The two got along day and night, and Xiao Baicai became fascinated by Yang Naiwu's versatile and unrestrained personality. This matter was noticed by the maid Ge Sangu. The two coaxed Ge Sangu into hiding, and Ge Sangu promised to keep it a secret.

Xiao Baicai has to be entrusted with him for life, and Yang Naiwu promises that when he wins the election, he will help Xiao Baicai and Ge Xiaoda dissolve their engagement, divorce Yang Zhan himself, and then marry her. The two exchange tokens. Xiao Baicai is full of joy and looks forward to it day and night, but she feels uneasy when she thinks about consummating her marriage with her fiancé, Ge Xiaoda.

The affair between Yang Naiwu and Xiao Baicai was finally discovered by Yang Naiwu's wife Yang Zhanshi and his sister Yang Shuying. Under pressure, they agreed to cut off the affair and concentrate on taking the provincial examination to gain fame. But Yang Naiwu still couldn't let go and met Xiao Baicai from time to time. Yang Zhanshi reminded Ge Xiaoda to consummate the marriage with Xiao Baicai as soon as possible. This aroused the alarm of Shen Yushi and Ge Xiaoda, and they discussed moving out of the Yang family as soon as possible. Xiaobaicai asked Yang Naiwu to discuss. Yang Naiwu advised Xiao Baicai to put her reputation first and cut off the affair immediately. Xiao Baicai was angry and resentful, accusing Yang Naiwu of only caring about fame and not showing his true feelings.

After moving out of the Yang family, Xiao Baicai refused to consummate the marriage immediately on the grounds that Ge Xiaoda's illness was not cured. Liu Zihe, the son of Liu Xitong, the magistrate of Yuhang County, was fascinated by cabbage at the Bon Festival. Liu Xitong's master Chen Zhushan designed Liu Zihe to rape Xiao Baicai. Xiao Baicai was in pain, and Ge Sangu tried to persuade her. Liu Zihe found that he could no longer let go, and his sincerity finally touched Xiao Baicai. The two fell in love and often met for trysts. Liu Zihe decided to change his appearance and vowed to marry Xiao Baicai. But due to Ge Xiaoda's trouble, he turned to Chen Zhushan to find a way. It happened that Ge Xiaodaliu suffered from fire again, so Chen Zhushan came up with a poisonous plan and secretly substituted longan and ginseng while Ge Sangu came to Airentang to buy medicine.

After Yang Naiwu passed the exam, he returned to his hometown to hold a banquet. He personally went to Xiao Baicai's house to invite his whole family to participate, and found Ge Xiaoda alone in bed. After explaining his purpose, he was driven away by Ge Xiaoda. Not far from the door, he was seen by Ge Sangu. Ge Xiaoda's old illness relapsed. Xiao Baicai fried the medicine that had been dropped and gave it to him to drink. His condition soon worsened and he died tragically. Shen Yu found that the corpse had changed shape and blood was bleeding from the mouth and nose, so she suspected that her son had died of poisoning. Shen Yu asked the local protector Wang Lin to write a petition and go to the county government office to beat drums and complain about injustice, pointing out that Xiaobaicai conspired with the adulterer to kill Ge Xiaoda.

Liu Xitong interrogated Xiao Baicai, and Xiao Baicai cried out for injustice. At the request of Liu Zaige's family, he opened the coffin and conducted an autopsy. Under the examination of his co-worker Shen Xiang, it was determined that Ge Xiaoda died of arsenic poisoning. Under coercion, Xiao Baicai confessed that Yang Naiwu poisoned Ge Xiaoda. Liu Xitong reported and bribed Chen Lu, the prefect of Hangzhou, demanding that Yang Naiwu be removed from his status as a civil servant. Chen Lu reported to Yang Changjun, the governor of Zhejiang, and Yang Changjun immediately submitted the title to the imperial court. Cixi summoned Weng Tonghe into the palace and discussed Yang Changjun's specific case. Weng Tonghe believed that the case must be heard before it can be concluded.

After receiving the approval, Liu Xitong immediately sent someone to take Yang Naiwu to the county government, where Yang Naiwu and Xiao Baicai were confronted in court. Xiao Baicai felt so miserable that she couldn't express it. Liu Xitong tried Yang Naiwu with severe torture, but Yang Naiwu finally surrendered. Liu Xitong asked Chen Zhushan to draft the criminal code of the Qing Dynasty and report it to the province for the crime of "Xiao Baicai murdered her husband and was executed in Ling Chi; Yang Naiwu was an adulterer who planned to steal his husband and wife". Yang's case reached the prefect of Hangzhou. Zhou Zheng, Chen Lu's famous criminal master, discovered flaws in the case file and asked the prefect to bring all the criminals in the Yang case to the province for personal trial.

Liu Xitong bribed Chen Lu, and Chen Lu was determined to make Yang's case a solid case. Xiao Baicai still insisted on Yang Naiwu in the lobby. Yang Naiwu shouted that he was wronged, and Chen Lu immediately beat Yang Naiwu violently. And asked where the poison came from? Yang Naiwu made up a random person. When the testimony was obtained, Yang Naiwu never expected that the person he made up was actually real, and he suddenly became desperate.

Just when Yang Naiwu was desperate, his friend Chen Dan suddenly came to visit him. When the court retrials the matter, the confession must be retracted. On the night of the trial, Liu Zihe came to the prison and persuaded Xiao Baicai to insist that Yang Naiwu was an adulterer.

When the trial started again, Xiao Baicai bit Yang Naiwu again, and Yang Naiwu passed out on the spot.

Weng Tonghe had reviewed all the files on the Yang case and was convinced that the case was an unjust case. He also found that many Zhejiang officials were involved, so he met with Cixi and urged him to take this opportunity to attack local powerful factions. Cixi sent academician Hu Ruilan to investigate the case. Hu Ruilan arrived in Zhejiang and interrogated Yang Naiwu and Xiao Baicai overnight until they were exhausted. In the end, he reported to the court that "the original charges in this case were found to be consistent with the investigation" and wrote the "Recruitment" in his own hand. At this time, Yang Zhan committed suicide in despair...

Yang Shuying arrived in the capital and asked Xia Tongshan to help her file a complaint to the Ministry of Punishment, but Xia Tongshan refused. Luo Xuecheng, secretary of the cabinet, approached Weng Tonghe and said that eighteen of them, Zhejiang officials from the capital, would jointly file a complaint with the Metropolitan Procuratorate and request that Yang's case be handed over to the Ministry of Criminal Justice for trial. Weng Tonghe agreed to meet Cixi to report the matter. Cixi asked Xian to remove these eighteen officials from their official positions and present them as common people. Yang Changjun was very happy when he learned that eighteen Zhejiang officials in the capital had been dismissed from their posts by the Queen Mother, and decided to make the Yang Naiwu case a solid case without any evidence.

Liu Xitong felt that the matter might be exposed, and under Chen Zhushan's persuasion, he prepared to send someone to secretly destroy Ge Xiaoda's body! But when he led his men to open Ge Xiaoda's coffin, they found that the coffin was empty.

The trial begins in the lobby of the Criminal Department, and Xiao Baicai still insists that the murderer is Yang Naiwu. Ge Sangu was brought to court, and it was said that Yang Naiwu had killed Ge Xiaoda. Weng Zenggui, Gang Yi, and Lin Gongshu announced that Yang Naiwu, Xiao Baicai, and Yang Shuying would be executed the next day. Yang Naiwu did not panic when he returned to prison, thinking that there must be a mystery to it. Sure enough, a jailer took him to a room, and Xiao Baicai was also brought in. The two met in a secret room, and Xiao Baicai finally revealed her true feelings. Weng Zenggui took Weng Tonghe, Xia Tongshan and others to eavesdrop, and sent someone to listen and record. After Xiao Baicai finished speaking, the secret door of the secret room opened, and Weng Zenggui, Gang Yi, and Lin Gongshu came out, and immediately asked Xiao Baicai to sign the confession.

Weng Zenggui and the others all thought the case could be closed. Xiaobaicai was sentenced to death in Lingchi, and Liu Zihe was executed immediately. But Weng Tonghe disagreed and proposed the idea of ??opening the coffin for an autopsy. He volunteered to ask for the edict, and Cixi finally issued the edict. After Cixi heard about Yang Naiwu's secret meeting with Xiao Baicai and told her true feelings, she asked Liu Zihe to also meet Xiao Baicai in the secret room.

Weng Tonghe arranged for Xiao Baicai to meet Liu Zihe in the secret room. Liu Zihe told that he was sincere to Xiao Baicai, and that he had never wanted to kill Ge Xiaoda. The two hugged each other and cried... Cixi and Weng Tonghe on the other side of the secret room were eavesdropping. Cixi said that she never imagined that these three people were all for the same word of love...

The men from the Ministry of Punishment came to Ge Xiao's grave, but the coffin they took out was empty. Weng Zenggui finally found out from Ge Sangu that Ge Xiaoda was buried in another place. The coffin was transported to Beijing to verify that Ge Xiaoda did not die of poisoning. Qian Tan had to point out the fact that he found that the medicine residue was full of longan and American ginseng. Wu Zuo admitted that Chen Zhushan sent longan and ginseng to Ge Xiaoda, which was actually the cause of Ge Xiaoda's death. The truth of the Yang case finally came to light.

When it comes to investigating and punishing derelict officials, two factions appeared in the court. Cixi summoned Weng Tonghe, deliberately revealing the difficulty of investigating and punishing derelict officials and the difficulty of attacking local powerful factions. Weng Tonghe knew what Cixi said, so he went to Wang Xin overnight and drafted a memorial to impeach Yang Changjun, Hu Ruilan and others for flouting the law and bullying the emperor, and urged them to be severely punished. After listening to the memorial, Cixi understood that the time had come, and personally declared that all the officials who failed to handle the Ge Pinlian case should be dismissed separately.

Chen Zhushan was executed, and Liu Zihe was sent to Xinjiang... Xiao Baicai went through many hardships and became a nun; Yang Naiwu could no longer regain his status as a scholar.

The Empress Dowager Cixi smiled proudly in the palace...
