First, the script answer
When the murderer is Qian Ershi.
Second, the story analysis
Qian Guangjin is a man who loves money and pleasure. When he was just developed, he abandoned his wife and young son and married a rich woman, thus becoming the boss of a big company.
For more than ten years, Qian Guangjin never took care of his eldest son Qian Ershi and his first wife Li Mei. Until two years ago, Qian Ershi was admitted to the university, but Li Mei fell ill because of more than ten years' hard work and had to spend money on hospitalization. Qian Ershi's mother and son certainly had no money, so Qian Ershi thought of his father in a city. Originally, he had no hope, but Qian Guangjin was unexpectedly accommodating, began to give alimony, and went out to eat from time to time like an ordinary father.
Later, Qian Ershi realized that this was because Qian Guangjin was arrested and divorced for cheating four years ago. In the past two years, he began to feel unwell, guilty and afraid of retribution for doing bad things, and began to want to make compensation. Qian Ershi is disgusted with Qian Guangjin, but for the sake of money, he can only maintain superficial fatherly love and filial piety.
One day, when Qian Ershi was at school, he saw his secretary, Wu Zhao, go in with Qian Guang to find Professor Changqing from the history department. He overheard what they were talking about and went down to ask Changqing out of curiosity.
Changqing didn't care at first, but after seeing the birthmark on Qian Ershi, he changed his attitude and told Qian Ershi the story of longevity chain.
According to legend, there was a senior official named Zhao in the Ming Dynasty. It is said that his wife and children died soon after he was young and in high school. At that time, people said that he was talented and blessed. A mysterious master admired his talent and sympathized with his experience, so he gave him a necklace called "Immortal Chain". Those who have this longevity chain will live forever and prosper. With the help of experts, the senior official surnamed Zhao put on the longevity chain, and it was really smooth sailing. In three years, he changed from a small county magistrate to a high-ranking official with one person in power. When he became the highest official, he had no chance of promotion. Soon after he was satisfied, he quit his job and traveled around. No one knows his whereabouts after that. All his people say that he is a fairy, because Wen Quxing came to earth and could not stay on earth for a long time.
This is just a legend for most people, but it is true for Changqing, because he is the legendary hero, Zhao Luzhi.
The function of longevity chain is not to make people young for hundreds of years, but to make people die when they are young and be reborn with memories. Evergreen is the third generation of Zhao Lu Zhi. In the first generation, Zhao Luzhi did win the highest prize at the age of 25, as legend has it. However, due to his lack of family background, he was only assigned to work in a remote county magistrate. When he took his wife and children to his post, his son was seriously ill because of the long journey and remained in poor health. To make matters worse, his wife Shi Li takes good care of him every day. Later, she went to worship Buddha and prayed for God to bring back a monk. The monk said there was a way to save the child. As long as you soak the fairy chain with your wife's painstaking efforts and bring it to your children, you will live forever and prosper.
Zhao Luzhi didn't believe it, but he couldn't stand his wife's pleading, so he cut his wife's left chest one night and shed a bowl of blood. The fairy chain soaked in the bowl quickly absorbed the blood. This strange scene made Zhao Lu Zhi tie the immortal chain around his neck and froze all night. In the morning, his wife and children were dead. Zhao Lu is unwilling to give up his future, and it is said that he has died of illness. Therefore, she was pitied by the emperor and rose to the top of the world. Indeed, as the monk said, she is very rich.
Three years later, just when Zhao Luzhi thought he would live forever, he suddenly became seriously ill and had a palm-sized black mark on his left chest, which could not be cured. He sent someone to find the monk, who waited for him for a while and found him. The monk told him that this was the only way to live forever, revealing his dark brown mark from his chest to his collarbone. Zhao Lu believed it, built a ancestral home and a secret room, moved all the treasures in the past, resigned and waited for immortality.
However, he died of illness and was reincarnated as a favorite of the Qing Dynasty. After being poisoned by others, he was made a prince. When the third world became Changqing, it was also a rich family but intrigued. The memory of his death in his last life is too painful. At the age of eight, Changqing went to his ancestral home and dug a hole in the ground, hoping to change the owner of the longevity chain. But it was seen by Wu Zhao, who was only five years old. Evergreen ran away and came back to find that the hole had been filled, and never found another chance. Originally, he had given up, because he was not sure where to be buried after death, so he had to move out of a rich family and become a poor professor.
I came to him with100000 yuan, hoping that he, a professor who studies the history of Ming and Qing dynasties, could help me think that the longevity chain might be in Zhao's ancestral home, thus defrauding the high price to buy the ancestral home. Evergreen agreed, and found that Qian Guangjin's son, Qian Ershi, also had a dark brown birthmark, which grew to the back shoulder. Changqing thought that the immortal chain was used to punish monks. The monk found himself a scapegoat, but he didn't escape, and he kept going round and round. Moreover, because he has no fairy chain and no memory, this is a godsend opportunity for his revenge. Therefore, Changqing told Qianer the story of Wanshou Chain and told Qian Guangjin how to use it.
Qian Guangjin had a bad idea, bought a house and gave it to Qian Ershi's mother and son for a pretence. He kidnapped Qian Ershi and went to the ancient house together, hoping to soak the immortal chain with Qian Ershi's blood. Qian ershi is very clever. He found out the relationship between the ancient house and the longevity chain and asked Changqing, who told him how to use it and took the opportunity to provoke the murder of Qian Ershi.
19 July 15 On the day of going to the ancient house, Zhao Silian, the head of the Zhao family, came to the study with six people, opened the secret room and left Changqing for the study. At night, others sleep in the study, and Zhao Silian sleeps next door.
At 06:30, Changqing waited until the next morning to secretly open the entrance and wake up others except Zhao Silian who slept in the next room, because there was no sleeping bag. Everyone brought their tools, and Qian Ershi took the ethylene and cotton cloth mixed with flunitrazepam in the waterproof bag and went down to the secret passage.
At 07:50, Zhao Silian was awakened and secretly followed. When he saw that they had found the grave, he knocked on the wall jealously and ran into the organ. The long thorn sticking out from the wall of the secret passage in front of the door trapped Changqing and them in the tomb. After getting the longevity chain, Changqing specially arranged for everyone to go to other doors separately to find a way out, and then left first with Qianer.
08: 15 Qian Ershi told Changqing about his plan to put Qian Guang into a trance and get the immortal chain first.
At 08:20, when Qian Ershi went to cover Qian Guangjin, Qian Guangjin got sick and suffocated with vomit. Before he died, he struggled to loosen the button on Qian Ershi's cuff. [08:35] After the plan was made, Changqing went to a place that could lead to other doors and shouted "You go this way, I will go this way" to Wu Zhao, creating an alibi for himself and Qian Ershi.
At 08:45, when he went back, Qian Er said that when he suffocated Qian Guangjin, Qian Guangjin might have strangled himself. Evergreen thought of using organs to create accidents, so as not to let everyone find that money is a suffocating method.
09:50 But they didn't expect that Luo Qiang, a villain, had the ability to avoid that long thorn. Although Qian Guangjin was stabbed to death, Luo Qiang carried the body back to his study and found that the immortal chain was gone, so he suspected it was artificial. Nanny Liu Xiu poisoned Qian Guangjin. Liu Xiu's ex-husband is Qian Guangjin's former competitor. In order to threaten Liu Xiu's ex-husband, Qian Guangjin instructed Luo Qiang to tie the children in a semi-decorated rural house. The poisonous air in the house made the child seriously ill and died. Liu Xiu saw Qian Guang coming in to look for her ex-husband while taking care of the children, only then did she know that Qian Guangjin was the culprit, and vowed to take revenge after the children got sick. She quit her job as a nurse, and went to a domestic company commonly used in Qian Guangjin to be his nanny. Using the pharmacological knowledge of nursing staff, she put the ground ostrich, a highly toxic metal, into washing powder, which can enter the human body through the skin. She washed Guangjin's pajamas with toxic washing powder, which poisoned Qian Guangjin slowly, but she couldn't find the reason. But Qian Guangjin knows the longevity chain. Liu Xiu overheard it and didn't want Qian Guangjin to know, so he asked Qian Guangjin to take her to the old house. On the night of arriving at the ancient house, Liu Xiu decided to put ostrich salt in Qian Guangjin's cup to prevent Qian Guangjin from getting a longevity chain, and wanted Qian Guangjin to drink water and inhale a certain amount of ostriches, and then fell ill and died.
At 08:45, after Qian Guangjin got the immortal chain, Liu Xiu and Wu Zhao went to find their way again. After being separated by a fork in the road, they returned to the grave ahead of time and checked Qian Guangjin's condition. They found that he had no breath, but his death was not what he expected. Zhao Chuan Silian knocked out Qian Guangjin and stole his safe. Zhao Silian's family was originally very rich, but since my cousin Wu Zhao (formerly known as Zhao Ya) broke into the secret room that only the heads of families could enter, it seems that Feng Shui has changed and his family has plummeted. Zhao Silian was cheated by her partner when she started her own business. He owed a large loan shark and had to buy a house. However, the house is so shabby that no one wants to buy it. At this time, Wu Zhao used a voice changer to pretend to be a young man's voice, called the Internet to contact, and said that he could find a buyer who was willing to pay a high price, but asked Zhao Silian to pay two million benefits. Zhao Silian couldn't agree, so he used Wu Zhao's method. He really cheated money into buying a house. Zhao Silian wanted to knock more money, but Qian Guangjin only bargained for half. When Wu Zhao transferred the money, he took 500,000 benefits first. Zhao Silian had no choice but to take Qian Guangjin to see the Chamber of Secrets first.
At 06:30, he thought they were just looking around. Unexpectedly, the history professor brought by Qian Guangjin was so powerful that he found the entrance the next morning.
At 07:50, Zhao Silian secretly followed after being awakened. When he saw Qian Guangjin, they found the grave successfully. In desperation, he knocked on the wall, pressed the switch and triggered the secret passage. Zhao Silian found that she could control the secret passage, and heard Chang Qing say that she should find her way separately, regardless of the money. So after they all left Changqing, Zhao Silian closed the office, thinking that such a noise would attract Qian Guangjin, but Qian Guangjin had been beaten half-dead by Qian Ershi.
08:30 So Zhao Silian had to walk by herself and saw Qian Guangjin leaning against the wall, but there was no response. First of all, in order to prevent Qian Guangjin from suddenly waking up, he hit Qian Guangjin on the back of the head with a flashlight in advance, and then touched Qian Guangjin's coat with a box, thinking that it must be something with a lifelong chain. He continued to look at the rest of the grave and found nothing, so he left.
At 09:40, Zhao Silian ran the wrong way because the light of her mobile phone was too dim. When he ran back, evergreen and they had returned to the grave. When I went to the study, evergreen's voice was very close. In desperation, Zhao Silian hid the box in a hidden corner of the bookshelf, and then rushed back to her room to change into sweaty clothes. After calming down, he pretended to be awakened and walked back to the study. Minister Wu Zhao used Zhao Silian to cheat money from Guangjin.
Wu Zhao's childhood name was Zhao Ya, and she was Zhao Silian's cousin. But because her father is not the eldest son, she can't inherit the position of ancestral home and patriarch, so she lives a very ordinary life. Wu Zhao's parents always take her to her ancestral home to ask her uncle, and Zhao Silian's father asks for money. Zhao Silian hates Wu Zhao and often bullies her. At the age of five, in order to avoid Zhao Silian, Wu Zhao ran to the Woods outside his ancestral home. He didn't go back until it was dark, but he accidentally walked behind his ancestral home and saw an eight-year-old child, Changqing, digging a hole outside the wall. Because of the hot weather, Changqing took off his coat, so Wu Zhao saw the birthmark on Changqing's left chest. Evergreen escaped after being discovered, so Wu Zhao got into the hole and came to the backyard garden where she had never been. Walking, she heard something in the study and wanted to go in and ask for directions. When she opened the door, she saw her uncle coming out of the secret room. My uncle flew into a rage because Wu entered a place that only heads of families could enter, and removed all the Zhao families of Wu from the Zhao family.
Wu Zhao moved to a neighboring city with his parents and changed his name. When she grew up, Wu Zhao became Qian Guangjin's secretary. Because she is beautiful, Qian Guangjin always eats tofu and is forced to accompany her. She wants to change her job, but she doesn't want to pay high salary. It happened that she learned from her parents that Zhao Silian's family was poor and wanted to sell the house, and Qian Guangjin was seriously ill, so she came up with a plan to sell the house to Qian Guangjin with the story of longevity chain.
After she contacted Wu Zhao anonymously, she bribed Chang Qing and Qian Guangjin was arrested as planned, but Zhao Silian's unreasonable proposal upset the plan. Fortunately, Changqing contacted her at this moment and told Qian Guangjin how to use the longevity chain, which made Qian Guangjin more convinced and thought of using his son. After that, Qian Guangjin bargained for five million yuan, demanding payment in two installments, with the second installment after the house inspection. Angry, Wu Zhao first transferred 500,000 benefits to himself, but worried that Qian Guangjin would regret it, he ordered a copy of Longevity Chain after consulting Evergreen. Luo Qiang, a thug, kidnapped Liu Xiu's son Luo Qiang according to Qian Guangjin's instructions, and followed Qian Guang into the hospital to find Liu Xiu's ex-husband. During their conversation, he heard Liu Xiu drop the hot water kettle while eavesdropping, so he saw Liu Xiu burn his left wrist.
Because after seeing Jiang Yuan, the dying son of Liu Xiu, in the hospital, Luo Qiang always felt guilty, especially after his child was born, Qian Guangjin began to get sick again, and Luo Qiang even demanded revenge. Two protective amulets were given to his wife and children, and an exorcist wore them himself. In order to avenge his children, he only focused on himself. Later, I learned that Qian Guangjin was going to find Longevity Chain, and bought medical supplies for trauma, a dagger, an anesthetic and a carry-on safe according to his instructions.
