In Bazhou, Sichuan, a Ba River is like a jade belt, winding between the mountains and mountains.

The old fisherman Yu Laohan sat at the stern of the boat, watching his son Yu Tiezhu at the bow pick up the fishing net, and threw it hard, the fishing net drew a beautiful arc, fell round in the quiet water, and slowly sank.

The weather is very good, the sound is clear, and it is already August day, and the river breeze is blowing slowly, which makes people particularly comfortable.

Yu Tiezhu slowly closed the net, and a pair of hopeful eyes looked at the river. The blue waves rippled, and the fishing nets slowly rolled up with the alternation of his hands. Gradually, I felt more and more heavy.

What's going on? Yu Tiezhu felt a little surprised, he and his father have been fishing for many years, and he still has a good feeling about whether there are fish in the net, how big the fish are, besides, this is just a small river, it is impossible to have a big fish that can't even pull himself, could it be that his net actually caught a school of fish!

He stared at the surface of the water with delight, wishing he could see silver-white fish leaping in their nets.

No fish, not a single one.

But the nets in his hand are getting heavier and heavier. Yu Laohan also felt a little surprised, drilled through the fish boat shed, came to the bow of the boat, saw Yu Tiezhu pulled a little hard, Yu Laohan was even more strange, many years of fishing experience told him, it must not be a fish, it is estimated that the net is caught in some dead branches or something, but you have to be careful, if you don't get it right, the fishing net will be torn.

Yu Laohan helped his son slowly pull the fishing net together, and little by little, the thing caught in the net finally came out of the water, and a big black strip floated in the water, I don't know what it was.

Yu Tiezhu lifted the fishing net upwards with force, and when he looked at it, it seemed to be a person leaning over! Suddenly startled, and his father glanced at each other, then he had the courage to flick the fishing net and turn the man over, and now he saw clearly, it was really a person, a dead man, a swollen dead corpse! His eyes were round, and he looked straight at him. Yu Tiezhu's mother screamed in fright, threw down the fishing net, sat on the bow of the boat, and almost fell into the river.

―――――――――――――

Bazhou Zhizhou Yamen, at noon, Xia Cicada screamed in the tree desperately, which was really annoying.

It has been almost a month since Yang Qiuchi came to Bazhou to be the governor. Before this, he first took Song Yun'er, Song Qing sisters, the little maid Hongya, Miao compatriots and sisters Shuang'er, Xue'er, Ke'er and other seven sisters of Liyuan, Master, follower Changfu, and a large group of maid servants such as Zhang Ma, the porter, under the protection of Nangong Xiong and Xia Ping's escorts, made a detour to Chengdu and visited Liu Ruobing.

Yang Qiuchi was very fortunate that he had the foresight to settle Liu Ruobing in Chengdu, Bazhou is not too far from Chengdu, and if you ride a horse, you can get there in three or four days.

Master Long is very good at doing things, he knows that Yang Qiuchi feels sorry for Liu Ruobing, he does not hesitate to spend money, there is no need to save money for Yang Qiuchi, so the family property purchased by Liu Ruobing in Chengdu is not as good as Yang Qiuchi's mansion in Wuchang, but it is also an elegant residence, with an elegant environment, small and exquisite, and a unique Jiangnan garden flavor.

Yang Qiuchi praised this garden and praised Master Long for doing things. Liu Ruobing was also very satisfied, Yang Qiuchi took Liu Ruobing to buy a few intimate maid servants in Chengdu, and many days have passed since all arrangements were stopped.

There is a time limit for this appointment, and it can't be delayed for too long, plus Liu Ruobing is pregnant with Liujia, and he can't be too affectionate, and Song Yun'er is also there, this intimacy also has some scruples, under the urging of Master Jin and others, plus Liu Ruobing's soft and hard work forced him to take office, Yang Qiuchi said goodbye to Liu Ruobing with tears, and took a large team of people to Bazhou for a long journey.

Sichuan Bazhou was also a remote mountainous area during the Ming Dynasty, although it was better than Zhenyuanzhou, but it was not much better.

Whenever he misses Liu Ruobing, Yang Qiuchi writes a letter to his family, telling the pain of lovesickness. The post stations of the Ming Dynasty were very developed, but compared to modern times, there was still a world of difference.

Yang Qiuchi wrote a letter to Liu Ruobing every once in a while, as if he wrote a letter home in college. Every time he went to four or five letters, Liu Ruobing only replied to one, with few numbers, but Yang Qiuchi had already found a treasure, and he turned over and over to see if it was enough, until he could recite it backwards, and he refused to put it down.

With the Hongyan Biography, although the two are far apart, they can also be heart-to-heart.

At noon that day, on a hot day, Yang Qiuchi was shaking a big pu fan, talking with the Song sisters and the pretty girl Hong Aya in the living room. I heard a chaotic sound, someone shouted an unjust complaint, and it was an emergency, is there a murder?

The porter Zhang's mother came to report that an old man who was fishing had reported that he had found a dead body in the Ba River and asked the old man to investigate.

Yang Qiuchi immediately instructed the yamen to go to protect the scene first, put on an official robe, took the forensic physical evidence investigation box, took the little tail Song Yun'er, hurriedly went out of the inner office, and under the protection of Nangong Xiong's personal guards, he called Master Jin and Yamen to work hard, 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 Yu Laohan and Yu Tiezhu how the father and son found the body, and then put on gloves and carefully examined the body.

The corpse was a man with a short green cloth shirt, and looked like a farmer, with a thin iron chain around his neck and a stone at one end. The stone is not too heavy.

Yang Qiuchi first searched the pockets of the corpse and found a sweat towel with the word "Li" embroidered on the corner. Nothing else was found.

Undressed for examination, it was found that the body had begun to be mild.

Song Yun'er also watched Yang Qiuchi carefully from the side to inspect the corpse, and suddenly sighed.

Yang Qiuchi asked, "What's wrong?" ”

"Brother, you said before that after a person dies, blood will be deposited in the lower part of the body and form corpse spots, why does this corpse not have corpse spots?" Song Yun'er followed Yang Qiuchi to investigate many corpses, listened to Yang Qiuchi a lot, and learned some special terms.

Yang Qiuchi praised: "Yun'er is so smart, you can still remember what I told you before, it's not simple." ”

Song Yun'er tilted her head proudly: "I can remember what you say, but I just can't use it." It's like this corpse, why is there no corpse spots? ”

"It's not that this body has no corpse spots, but that the color of the corpse spots is very light and not easy to find. Moreover, corpses drowned in rivers are generally not deposited in the lower parts of the human body. ”

"Why?"

"Because although the corpse has a stone tied with an iron chain around its neck, the stone is not too heavy, and the chain is relatively long, so the corpse cannot be kept in a posture, and the river is flowing, and the corpse rolls up and down, and there is no fixed position, so it can no longer form corpse spots in a fixed low position."

This truth is actually very simple, but Song Yun'er didn't expect it for a while, Yang Qiuchi broke this point, and immediately understood, nodded, looked at it carefully, and said in surprise: "I found out that there are corpse spots, scattered all over the body, but ...... The corpse spots we examined before seemed to be purple-red, so why are the corpse spots of this one pink? ”

This problem is not easy to explain to Song Yun'er, because the body of the drowning person is in the water, and the temperature is relatively low, so after the formation of corpse spots, oxyhemoglobin in the blood is not easy to decompose, and the oxygen in the water will enter the blood vessels and form a high concentration of bright red oxyhemoglobin, so the corpse spots of the drowned are not ordinary purple red, but pink.

The issues involved are so modern that Yang Qiuchi can only simply say: "This is because of water cooling." ”

Song Yun'er couldn't understand why the water cold would make the corpse spots pink, and was about to get to the bottom of it, when she suddenly stared at the corpse's mouth and nose, and exclaimed in surprise: "I know, this person was poisoned and thrown into the river!" ”

Yang Qiuchi looked at her in surprise: "How do you know?" ”

Song Yun'er pointed to a white bubble slowly emerging from the mouth and nose of the dead corpse: "Look! If he hadn't been poisoned, how could he have so much foam coming out of his mouth and nose? ”

Yang Qiuchi shook his head: "Really...... If the mouth and nose are bubbling, must it be poisoned? ”

"Didn't you poison it, did you...... Could it be that he deliberately spit bubbles? - Is he still alive? Song Yun'er's eyes widened.

Hearing her words, Yang Qiuchi's head was even bigger: "This corpse is swollen and starts to [***], how can it still be alive!" And you also saw just now, there are pink corpse spots on the corpse, how can a living person have corpse spots! ”

"Then, how can his mouth spit bubbles!"

"What spit bubbles, that is called mushroom-like foam, because the cold water enters the respiratory tract, stimulates the mucous membrane of the respiratory tract and secretes a large amount of mucus, the deceased's rapid breathing after falling into the water will mix and stir these mucus with the water inhaled and the air in the respiratory tract and lungs, this kind of foam will be formed, because it is very similar to the foam spit out by crabs, it is also called crab-like foam."

Song Yun'er didn't know much about respiratory tract or anything like that, but she was used to listening to Yang Qiuchi's strange words.

Yang Qiuchi took a sweat towel, gently wiped the foam off the deceased's mouth and nose, and said, "Even if you wipe off this foam, it will still come out, especially when you turn the corpse, it will bubble up even more." ”

Sure enough, a fine white foam slowly emerged from the corpse's mouth and nose.

Yang Qiuchi continued: "This kind of foam can indicate that the deceased's respiratory function was still present when he entered the water, so as long as the drowned corpse is found to spit out this foam, to some extent, it can indicate that he entered the water before his death, that is, the deceased was drowned." However, it is not necessary that taking certain poisons or dying from epilepsy can also produce this foam. ”
