Lu Jinping glanced at the stunned villagers and continued: "I checked Eleventh Lady's body, face, lips and fingernails, because she was a typical characteristic of being smoked by miasma in the toilet. She died of being covered by the mouth and nose. After I checked her internal organs after dissection, it was consistent with this characteristic. This proved my inference. Of course, a more powerful evidence is that this fat pig simulated Eleventh Lady's experience yesterday and used its life to prove the existence of the terrible murderer of Miasma."

The miasma in the toilet mentioned by Lu Jinping is actually the regular scientific name of hydrogen sulfide. It has a foul odor of rotten eggs. It is an acute and highly toxic substance. It is a nerve agent. It is an asphyxiating and irritating gas. Inhaling high concentrations of hydrogen sulfide can cause death in a short period of time. It can cause hypoxia in cells and form internal asphyxiation. Therefore, the appearance of characteristics similar to mechanical asphyxiation on the surface of the corpse and internal organs is easy to make people think it is murder.

Lu Jinping and Ye Qingqing were walking in the village before, but they couldn't figure out who was killed by Eleventh Lady. At this time, someone was digging a cesspool on the road they passed, and the stench floated over. Ye Qingqing said, "It's so stinking." It was this sentence that reminded Lu Jinping that he thought that the feces would ferment quickly under high temperatures, producing a large amount of hydrogen sulfide. Therefore, Eleventh Lady was not actually murdered, but was stinky by the smell of feces and urine in the cesspool. To be precise, it was poisoned to death by the large amount of hydrogen sulfide produced by fumigation under the sun in the closed toilet.

In an old-fashioned toilet with cesspools, if the ventilation conditions are not good, if you enter under the scorching sun, you will feel your eyes burning and your mouth and nose are uncomfortable, which is caused by the stimulation of hydrogen sulfide.

Eleventh Lady was miserable and unlucky. She encountered a toilet exposed to high temperatures. The door was also closed and the window was not opened. The ventilation conditions were very poor and the hydrogen sulfide concentration inside was very high. This caused her to be poisoned and died soon.

In order to prove this inference, Lu Jinping immediately returned to his residence and examined the extracted deceased's efforts.

In the deceased's heart and blood, he tested hydrogen sulfide several times more than the normal value, proving his inference.

Of course, there is a question here, that is, why only Eleventh Lady died in this toilet. Others are fine.

This has been explained from previous investigations, because the toilet was newly built this year and has not been exposed to the scorching sun last year. The high temperature of this summer has appeared in these days and has not appeared before. The vegetable farmer does not go to the toilet, but is just used to accumulate feces collected from various villages, so he escaped the bad luck. Eleventh Lady is a woman, and the toilet is on the roadside, so she dare not open the door like a man. So she is stuck inside and poisoned and forgotten.

Lu Jinping raised his voice and said, "I'll call you all to tell you. The toilet must not be closed tightly. Of course, to cover up the shame, there must be a door, but there must be a ventilation vent above the toilet, especially in the hot summer. Otherwise, under the sun, feces and urine will form miasma and poison people to death. The encounter between Eleventh Lady and this pig. I think it is enough to alert everyone."

Hearing Lu Jinping's words, the onlookers looked at each other. The facts they witnessed made them believe what Lu Jinping said, and they nodded frequently, with horror and fear on their faces.

Lu Jinping said to the village: "Call people immediately to renovate the vegetable farmers' toilet, open the windows, and ventilate them. Make sure there is no scent that stimulates the eyes inside, and then check all the toilets in your village one by one. If there are any toilets like vegetable farmers that are closed on all sides, renovate them immediately so that no one will be injured again. This kind of tragedy must not be repeated."

The village was busy agreeing, but the vegetable farmers and others kneeling on the ground didn't know what it felt. The vegetable farmers couldn't imagine that the one who killed Eleventh Lady was actually the closed toilet he built on all sides, and they couldn't help feeling extremely sad.

Jia Feng stared blankly at the dead pig on the ground. He thought that his Eleventh Lady was killed by someone, but he did not expect that it was smothered by the miasma caused by the scorching sun. The miasma would poison people. The people knew that Lu Jinping's explanation was acceptable. The test of this fat pig that he witnessed also confirmed Lu Jinping's inference. He felt very sad. If he had known this, why would he have to wait under the willow tree? Why didn't he have the courage to go directly to her house to pick her up? In that case, Eleventh Lady might have escaped this bad luck.

Chunhua Building opened, and the owner personally sent invitations to Lu Jinping.

Chunhua Tower is a luxurious Qin Tower in Tongzhou. In the Tang Dynasty, Qin Tower was legal and profitable, and it was also an important source of tax revenue for the court. Therefore, the court was very welcome to opening such places. Moreover, the Tang Dynasty literati and poets sleep in flowers and drunken willows, and many Tang poems were written in Qin Tower. Many famous poets were also frequent visitors to Qin Tower. Therefore, it was not embarrassing to enter and exit Qin Tower in the Tang Dynasty.

However, Lu Jinping was a great young man from modern society, how could he get involved in such a place? He was disdainful, but with the invitation, he also sent a trunk of gifts. After opening it, it turned out to be a top-notch silk and satin, and a box of copper coins. The number really made him feel a little moved.

The invitation only allowed him to attend, and did not ask him to cut the ribbon and post a speech, probably to let him recharge the scene. After all, he is a seventh-rank official and has a title.

The owner of Chunhualou is named Ma. Because his family is rich, he is called Ma Qianzhu. Chunhualou is his biggest deal and the money tree he is looking forward to. When Ma Qianzhu sent invitations to Lu Jinping, he hinted intentionally or unintentionally that he also sent gifts and invitations to other major officials in the yamen, including Feng, the governor of the yamen.

The explanation from the rich man Ma finally found an excuse. Since ancient officials could go to these places, why couldn't they go to them? They were not just visiting the kilns, but just attending their opening ceremony. In ancient times, Qin Tower was a legal industry, which was equivalent to attending the company's ribbon-cutting ceremony now. It was no big deal. As an official of the court, supporting local economic development was also one of the tasks. Of course, in modern society, participating in such activities would not be able to accept gifts, but in ancient times there was no restrictions on this. Lu Jinping asked the people below and confirmed that the rich man Ma said there was nothing wrong with it, so she accepted the invitation.

Qinlou held its opening event at dinner. Lu Jinping first returned to his residence, took off his official uniform, changed into casual clothes, and had a round-necked long gown. He felt it was not appropriate to go to such an event. He was about to take Ye Qingqing out to attend the celebration, but the concierge suddenly ran to report that Yunzi was coming.

After Lu Jinping was taken away by Lu Niang's wife Lu Niang, Yunzi once took someone to the river to look for him for a day. The affection contained in this touched Lu Jinping very much. After that, Yunzi also came to chat with her, but neither of them had ever gone out.

Now that Yunzi is here, Lu Jinping is about to go out and has no time to chat with her. However, he still quickly came to the flower hall first. Seeing Yunzi sitting there a little lost, as if he was full of thought, Lu Jinping couldn't help but feel a little surprised, so he walked up to her and bent down to look at her, saying, "What's wrong with you? Why are you in a daze?"

This time, Yunzi woke up from his dream, screamed, stood up and looked at him, and said angrily: "Why did you come to someone quietly? Don't say hello, do you want to scare people to death?"

"You are distracted and unconscious. I didn't feel quiet when I walked in. What's wrong? Is there anything wrong?"

Yunzi sighed and said, "It's nothing."

"Okay, your face is full of things. Although I don't know what it is, I know, it will definitely make you very unhappy. Tell me, what's the matter? Maybe I can enlighten you."

Yunzi looked at him: "If you can really help me, I have to thank you. Unfortunately, I am afraid that you are not old enough to help."

Lu Jinping's eyes rolled, and the people understood a little, and said, "Is it because your Tubo proposal to marry, the emperor has not agreed yet?"

Yunzi nodded and said, "You are so smart. You can guess it as soon as you guess. Alas, a few days ago, my father sent another letter from Tubo to you Emperor of the Tang Dynasty, and mentioned the marriage of marriage again. After I submitted the letter, the emperor and the queen sent a female official to tell me that Princess Jincheng is too young and the queen felt sorry for her and wanted to keep her for a few more days. So, let us wait patiently without worrying. The emperor will not regret it. However, I have been waiting here for almost a year. The emperor always said that the princess was too young and could not bear to leave now. When will it take? How long will it take? Alas, I feel annoyed when I think of these things, so I want to find someone to talk and relieve my boredom."

Lu Jinping knew that Princess Qingcheng had married in Tubo in history, and he knew the result, but to be honest, he was indeed not interested in the marriage, and did not want to talk to him more about it. He just smiled and said, "Since you are in a bad mood, should you go with me to relax?"

Yunzi couldn't help but be overjoyed when he heard this and said, "Okay! Where can I go to relax? But it's getting late now, and it will be dark if I can't get too long."

"It's dark, of course there's a way to play it. I'm afraid you won't want to go after hearing it."

Yunzi looked at him curiously and said, "What is it? Where are you going? It's so mysterious."

Lu Jinping took out the invitation from Chunhualou and handed it to her and said, "A Qinlou has opened its business and asked me to enjoy the whole family to have a meal. I heard that there are many famous actors in this Qinlou. Ma Qianzhu spent a lot of money to invite him from the capital. He can be regarded as a figure in the capital. He has both sexes and art. How about it? Are you interested in opening your eyes?"
