In Bazhou, Sichuan, a Ba River is like a jade belt, lingering among the steep mountains.

Old fisherman Yu sat at the stern of the boat, looking at his son Yu Tiezhu at the bow of the boat, picked up the fishing net, threw it away, the fishing net drew a beautiful arc, landing in the quiet water, slowly sinking.

The weather is very good, the sun is sunny and it is now August, and the river breeze blows gently, making people feel particularly comfortable.

Yu Tiezhu slowly closed the net, his eyes full of hope looked at the river, and the blue waves rippled. The fishing net slowly rolled up as his hands alternately closed, gradually feeling heavier and heavier.

What's going on? Yu Tiezhu was a little surprised. He and his father had been fishing for many years. He still had a lot of feelings about whether there were fish in the fishing net and how big the fish were. Besides, this is just a small river. It is impossible for a big fish that he can't even pull. Could it be that his own net actually had a group of fish!

He stared at the water with joy, hoping to see the silver-white fish jumping in the fishing net.

There are no fish, not one.

However, the fishing net in his hand was getting heavier and heavier. Old Man Yu felt a little surprised. He walked through the fishing boat shed and came to the bow. When he saw Yu Tiezhu was struggling, Old Man Yu was even more surprised. Years of fishing experience told him that it was definitely not a fish. It was probably because he had some dead branches and other things to live in. But be careful, if it was not done properly, the fishing net would be torn.

Old Man Yu helped his son slowly pull the fishing net together. Little by little, the things that were occupied by the net were exposed to the water. A large black strip was floating and sinking in the water. I don’t know what it was.

Yu Tiezhu lifted the fishing net up hard, looked closely and seemed to be a person leaning over! He was shocked and looked at his father, then he had the courage to throw the fishing net together and turned the man over. Now he saw clearly. It was really a person, a dead person, a swollen corpse! His eyes widened and he looked at him directly. Yu Tiezhu was so scared that he screamed, threw down the fishing net, sat down on the bow of the boat, and almost fell into the river for a review.

At noon, the summer cicada was screaming at the tree with a lifeless voice, which was really annoying.

It has been almost a month since Yang Qiuchi came to Bazhou to be the magistrate. Before that, he took Song Yuner, Song Qing sisters, the little maid Hong Ling, the Miao sisters Shuang'er, Xue'er, Ke'er and other seven sisters, the master, the follower Chang Fu, and the concierge Zhang Ma and other maids and servants. Under the protection of Nangong Xiong and Xia Ping's guards, he detoured through Chengdu and visited Bai Ruobing.

Yang Qiuchi was very glad that he had the foresight and settled Bai Ruobing in Chengdu. Bazhou was not too far away. He could reach it in three or four days if he was riding a horse and lying on his clothes.

Master Long is very good at doing things. He knew that Yang Qiuchi felt sorry for Li Ruobing and he spared no expense. There was no need to save money for Yang Qiuchi. Therefore, although the property purchased by Li Ruobing in Chengdu was not as good as that of Yang Qiuchi's luxury house that revitalized the economy, it was also considered an elegant residence with an elegant environment, small and exquisite, and a unique Jiangnan garden style.

Yang Qiuchi was very upset about the garden and praised Master Long for his ability to do business. Xiao Ruobing was also very satisfied. Yang Qiuchi took Xiao Ruobing to buy a few caring little maids and servants in Chengdu. All arrangements have been done.

There is a time limit for this rush to get out of office, and it cannot be delayed too long. In addition, Li Ruobing is pregnant and cannot be too intimate. Moreover, Song Yuner is also there, and there are some concerns about this intimacy. Under the urging of Master Jin and others, Li Ruobing uses both soft and hard force him to take office. Only then did Yang Qiuchi and Li Ruobing leave with Li Ruobing and took a long journey to Bazhou with a large group of people.

In the ambiguous period, Sichuan Bazhou was considered a remote mountainous area. Although it was better than Zhenyuanzhou, it was not much better.

Whenever he misses Bing Ruobing, Yang Qiuchi writes letters from home to tell the pain of longing for love. The post stations in the Ming Dynasty were very developed, but compared to modern times, there is still a world of difference.

Yang Qiuchi wrote letters to Li Ruobing every now and then, as if he was writing a letter from a family in college. Every time he went to four or five letters, Li Ruobing replied to the letter. There were only a few numbers, but Yang Qiuchi was already feeling treasured. He looked over and over again and again and didn't even want to let go until he could recite it backwards and refused to let it go.

With the letter from Hongyan, although the two are far apart, they can still be in harmony with each other.

At noon that day, on a hot day, Yang Qiuchi was shaking a big palm fan, talking with the Song sisters and pretty girl Hong Ling in the living room, and the hymn sounded loudly, and someone shouted for complaints, and it was an emergency. Is there a murder case?

The concierge Zhang Ma came to report that an old man who mortgaged the fish and reported that a dead body was found in the Bahe River and asked the master to investigate.

Yang Qiuchi immediately ordered the yamen to inform the yamen to go to the protection site first. He put on his official robe, took the forensic physical evidence investigation box, and hurried out of the inner yamen with his little tail Song Yuner. Under the protection of Nangong Xiong's personal guards, he called Master Jin. The yamen was offended and came to the Bazhou River in an official sedan chair.

The body had been pulled to the shore and covered with a straw mat.

Yang Qiuchi first asked the story of the old man Yu and Yu Tiezhu and his son when they discovered the body, then put on gloves and carefully examined the body.

The man in a corpse was wearing a short blue cloth shirt and looked like a farmer. He had a thin iron chain tied around his neck and a stone tied to one end. The stone was not too heavy.

Yang Qiuchi first searched the pocket of the body, found a sweat towel, and the word "Li" was embroidered on the corner, and nothing else was found.

Unlocked the clothes and found that the body had begun to be slightly corrupted.

Song Yuner also looked at Yang Qiuchi carefully inspecting the body, and suddenly exclaimed.

Yang Qiuchi asked: "What's wrong?"

"Brother, you have said before that after a person dies, blood will be deposited to the low point of the body and form corpse spots. Why is this corpse without corpse spots?" Song Yuner followed Yang Qiuchi to investigate many corpses. After hearing Yang Qiuchi talk too much, she also learned some special terms.

Yang Qiuchi praised: "Yun'er is so smart. You can still remember what I told you before. It's not easy."

Song Yuner tilted her head proudly: "I can remember everything you say, but I just can't use it. For example, why is this invoice free of corpse spots?"

"This corpse is not without corpse spots, but the color of the corpse spots is very light and not easy to find. Moreover, corpse spots that are swim in the river generally do not deposit at the low points of the human body."

"Why?"

"Because this corpse has an iron chain tied up a stone on its neck, the stone is not too heavy and the iron chain is relatively long, so the corpse cannot be protected in a posture. The river water is flowing, and the corpse rolls up and down, and there is no fixed position, so it cannot form corpse spots at a fixed low position."

This principle is actually very simple. However, Song Yuner hadn't expected Yang Qiuchi to break up, and she immediately understood. She nodded, looked carefully, and said in surprise: "I found that there were corpse spots scattered everywhere in my body. But the corpse class that used to examine the corpse seemed to be purple-red. Why was this corpse spot pink?"

This problem is difficult to explain to Song Yuner clearly. Because the body of the drowning person is in water and the temperature is relatively low, the oxygenated hemoglobin in the blood is not easy to decompose after the corpse spots are formed. Moreover, the oxygen in the water will enter the blood vessels to form a bright red oxygenated hemoglobin with a high concentration. Therefore, the corpse spots of the drowning person are not ordinary purple-red, but pink.

The problem this affected is too modern, and Yang Qiuchi can only simply say: "This is caused by water cooling."

Song Yuner didn't understand why the water cold made the corpse spots pink. She was about to dig the bottom of the problem, but suddenly stared at the mouth and nose of the corpse, and shouted in surprise: "I understand, this person was thrown into the river after being thrown by Pohu! "

But he looked at her in surprise: "How do you know?"

Song Yuner pointed to the dead body's mouth and nose and slowly sprinkled a bunch of white foam: "Look! If it weren't for being poisoned, how could such foam appear in the mouth and nose?"

Yang Qiuchi shook his head: "Is the mouth and nose really bubbled, must it be poisoned to death?"

"It's not poisoned to death. Did he deliberately spit bubbles? - Is he still alive?" Song Yun'er's eyes widened.

Hearing her words, Yang Qiuchi's head was even bigger: "The corpse is swollen and begins to rot, how can it still be alive! And you saw it just now that there are pink corpse spots on the body. How can corpse spots appear in living people?"

"Then, how could his mouth be bubbled!"

"What is bubble sprinkling? It is called syllable foam. Because cold water enters the respiratory tract, stimulating the respiratory mucosa and secretes a large amount of mucus. The rapid breathing of the deceased after falling into the water will suck this mucus with the air in the airway. The air in the lungs will be mixed and stirred, and this foam will be formed. Because it is very similar to the foam sprinkled out by crabs, it is also called crab-like foam."

Song Yuner couldn't understand any respiratory tract, but she was used to listening to strange and sarcastic words like Yang Qiuchi.

Yang Qiuchi took a sweat towel and gently wiped the foam from the mouth and nose of the dead man, saying, "Even if you wipe this foam off, it will not be too rare to pop up, especially when turning over the corpse, it will explode more."

Sure enough, a splash of white foam slowly emerged from the mouth and nose of the corpse.

Yang Qiuchi continued to add: "This kind of foam can indicate that the deceased's respiratory function still exists when entering the water. Therefore, as long as the drowning corpse is found to spit out this foam, it can be said that it was entering the water before his death, that is, the deceased was drowned, but it may not be necessary. Taking certain poisons or dying from epilepsy may also produce this foam."
