The mother of the second dog shouted grievances while begging her mother-in-law not to target herself so much for the sake of the child. The mother-in-law believed that her daughter-in-law had killed her son, so not only was she reluctant to change her story, but she also said that the child was most likely not her own grandson, and she did not admit that the child was her descendant. Ergouzi's mother shouted many times but was beaten back, because the county official had already decided the case and been approved by the superiors, if it was retried, it would mean that the county official was wrong, and his superior, the prefect, was also wrong. In order to maintain their face and dignity, they will never allow the mother of the second dog to overturn the case. Ergouzi's mother was a felony murderer, so she was escorted to Beijing and imprisoned in the prison of the Criminal Department, waiting for the child to be born and killed with a knife. At this time, Ergouzi's mother was already scared by the yamen, and she didn't dare to shout injustice or make trouble.

When the second dog was born, because of the bad mood and the lack of nutrition in the prison, the mother who had a difficult birth almost couldn't give birth. Fan Heng's child has no family, and his mother will be killed when she gives birth to a child, so no one cares about the life or death of the mother and son. Maybe the mother's moaning was frightening, or the people in the prison were kind to the people who drank alcohol, and finally a man in the male cell spent the price of two coarse grain steamed buns and asked the inmates in the female cell to help the mother of the second dog deliver the second dog. Fortunately, Ergouzi's mother was born in a villager, not only used to rough and rough breeding, but also had a good physique, and finally persevered and gave birth to a child. The female prisoner didn't know what the relationship between the person who hired her was the mother of Ergouzi, so she sent the child to the men's cell in a random bag. Originally, there was no room for men and women to interact with each other, but there were always exceptions, and besides, the prisoners here were all people waiting to die, so there was no need to be too strict. Soon after the child was sent there, the man in the men's cell asked for the child's mother. The jailer didn't agree, but for the sake of the child's mother's imminent death, he agreed.

Ergouzi's mother hugged her hard-working child and thanked her benefactor for saving her life, but the other party asked Ergouzi's mother some inexplicable words. Then the other party told Ergouzi's mother that he knew the cause of death of Ergouzi's father, which could prove that Ergouzi's mother was not the murderer of her husband. She didn't have the courage to live anymore for the sake of her child and to be able to watch her child grow up, so she finally decided to work hard again. She took the opportunity of her last interrogation before dying, and she finally cried out her wrongs. Of course, the people in the criminal department would not believe it, and Ergouzi's mother repeated the words of the benefactor, saying that she was not a murderer, let alone a person who murdered her husband. The officials of the Criminal Department recorded the words of Ergouzi's mother, and they needed to check the authenticity of the incident.

It is said that the life of Ergouzi's mother should not be extinguished, and the official of the Criminal Department who went to check the case happened to be the opponent of the county official, and in order to target the county official, he used the case of Ergouzi's mother to take down the county official. The county magistrate was dismissed from his post on charges of arbitrarily convicting the murder case, and the criminal department re-opened the case of Ergouzi's mother, and in the face of facts and evidence, Ergouzi's mother was acquitted and released. The so-called evidence is a leaf of oleander, which was found by Ergouzi's mother on her husband's body, and she kept it with her as a souvenir. After the child was born, the leaf and the child were wrapped together for the man in the cell to be seen, and the other party determined that the father of the second dog had eaten oleander leaves by mistake and died, not by the mother of the second dog, according to this leaf and the death of her husband's mother. But Ergouzi's father was tired and hungry, and ate under the oleander tree. Just a few leaves fell into the meal, he didn't care about it and just pushed the leaves away, but he didn't expect that the toxins of the leaves had been left in the meal. When he gulped down, it was equivalent to eating the poison in his stomach, and the father of the second dog was allergic and prone to allergies, so the poison attack was relatively fast. When he felt that something was wrong, he could no longer speak or move, foaming at the mouth and convulsing all over. He was not mistaken, he was poisoned, but he was not poisoned to death, and oleander poisoning caused by allergies.

Ergouzi's mother was acquitted, but her mother-in-law was unwilling to admit the daughter-in-law and grandson for the sake of her own face. Because the mother-in-law constantly slandered the reputation of her daughter-in-law in her daughter-in-law's case, and even said that the child was a sinful seed, she couldn't slap herself in the face, so she had to harden her heart and deny these two close relatives. Ergouzi's mother had nowhere to go, and she wanted to repay her benefactor, so she returned to the prison of the Criminal Department. Ergouzi's mother is a kind and determined rural woman who is unwilling to be an ungrateful person, and she wants to take care of her benefactor. Because Ergouzi's mother doesn't know how to read and can't do business, the people in the criminal department let her wash and cook for the prisoners in the big guy, which can be regarded as pitiful for the homeless mother and son.

The nickname of the second dog was taken by his mother, and it is said that it is a cheap name to make a living, and the nickname of the second dog in the countryside is very ordinary, and it is found in almost every place. Ergouzi's background is pitiful, so everyone cherishes him very much, knowing that Ergouzi's mother has no milk because of lack of nutrition, causing Ergouzi to cry all day long, everyone has taken out what they are usually reluctant to eat to Ergouzi, mother and son. In the prison, not only are the prisoners not free, but they are deprived of the little food they eat, so how difficult it is to save a little food. These foods can allow others to do things for themselves, and they can also increase their own physique when they are sick, so they are very valuable. Ergouzi's mother has also been in prison, and she knows that everyone gives not only food, but also very heavy love and conscience.

Gradually, Ergouzi grew up in the prison of the Criminal Department, a place that outsiders felt was very mysterious and terrifying, and he still liked life here compared to the outside world. Outside, everyone looks down on him, whether it is food or play, they need money, and he and his mother will be looked down upon if they don't have money. In prison, everyone loved him, not only telling him stories, but also giving him something to eat. There is also a jailer Lao Li who has a unique skill, and often catches some mice and treats them and then adds food to the second dog. After the second dog learns to bring messages and notes to prisoners, he doesn't have to worry about going hungry.

When Ergouzi was seven years old, his mother died in an accident, and Ergouzi became an orphan. The adults sent him back to his grandmother, but he was not used to getting along with her, and her grandmother often spoke ill of his mother in front of him. How many times did he quarrel with his grandmother because of this, and she said that he would beat him with a stick if she said that she couldn't do it. He had no choice but to escape back to the prison of the Ministry of Punishment, he felt that this was his real home, and only here did he feel safe and comfortable. Under everyone's pleading, Ergouzi became the youngest handyman in the prison of the Criminal Department, responsible for taking care of and serving some prisoners who were seriously ill and unable to move.

It may be that Ergouzi was influenced by some prisoners, and as he grew up, he began to adjust his oil cavity. A habitual offender also taught Ergouzi some skills to open the door and pick the lock, and Ergouzi could open the door of any cell without a key. A condemned prisoner used a lot of money to lure the second dog to open the lock for him, and the second dog was almost moved. For this reason, the prison manager of the Criminal Department gave Ergouzi a hard lesson, saying that he would drive Ergouzi out of the Criminal Department prison. Ergouzi knew that he had done something wrong in this matter, so he begged the steward not to kick him out of the prison of the Criminal Department. In front of this jailer who is good for him, Ergouzi swore that he would never use this kind of ability to be a traitor, in fact, the jailer is also for the good of Ergouzi.

When Lu Peiran offended his boss and was assigned to the prison of the Criminal Department, he happened to be the superior of Ergouzi. Lu Peiran didn't like this usually oily subordinate very much at first, but after a long time, he found out that Ergouzi was a more conscientious person in the prison of the Criminal Department. Second, dogs often give messages or do things to some prisoners without pay. Some of the people who were forced in by the higher authorities to force them to confess their crimes, after being tortured, he would also quietly send some cheap wound medicine, and even personally administer medicine to the prisoners. Persuade the prisoner to admit some crimes without a reason. There was a scholar who was framed and imprisoned in the prison of the Criminal Department because he offended a rich man, and after a beating, he was not only covered in injuries, but also inflamed because of improper treatment. The second dog carried a bucket of prisoner's urine into it, and poured it on the scholar's body. Others will think that Ergouzi is bullying people and taking advantage of this opportunity to bully scholars, but they are actually saving the lives of scholars. Urine can not only stop bleeding and reduce inflammation, but also allow the injured person to reduce fever as soon as possible, so as not to aggravate the injury. Urine treatment is a simple and cost-effective way to treat injuries after being tortured in the prison of the Ministry of Punishment, and there is no medicine for the prisoners to squander. The scholar not only has no money, but also does not understand the world, and will not give the second dog any benefits, nor will he please the second dog. So Ergouzi did not do this to ask the scholar to repay him, but to sincerely sympathize with the scholar. The scholar didn't know until he left that Ergouzi was not abusing himself but helping himself, and for the first time, the scholar bowed his noble head to Ergouzi. Lu Peiran began to be optimistic about this second dog, and cultivated and took care of him as his own brother.
