A handsome young wife suddenly came out of the inner room. Taking advantage of the light on the street, Chen Ying found that the young wife still had tears on her face. The young wife looked at Chen Ying timidly, and Chen Ying also found that the young wife still had tears on her face. I think it was her who choked just now.

The young wife looked at Chen Ying, Liang Zan and other Tang soldiers, and quickly retreated back to the inner room.

Chen Ying touched his nose and couldn't help but feel depressed. Is he a hungry person?

In fact, this young wife cannot be blamed for being too careless. At the end of the Sui Dynasty, the thirty-six lines of rebellion against the kings, seventy-two lines of dust and smoke, and there were more than one million soldiers and horses across the country, but it was really hard to tell the difference between the soldiers and bandits.

Chen Ying didn't care too much either.

The old man said: "There is meat, but no one does not have it. What's the use of meat?"

Chen Ying was puzzled. Liang Zan took a torch from his personal guard, and the torch shone the small room as if it were daylight. At this moment, Chen Ying suddenly found a body lying in the main room.

This corpse looks like it is not old last year, and is about 20 years old, with a blue-purple face.

Seeing this corpse, Chen Ying gradually became confused.

"Mr. Jun Ye doesn't need to watch it. It's charcoal poison. This is all fate!" The old man's tone was cold, without any human emotion. I think it would be a big blow to the old man when he lost his son in his old age.

The so-called carbon toxicity is what later medically calls carbon monoxide poisoning. The binding ability of hemoglobin to carbon monoxide in the blood is more than 200 times stronger than that of oxygen, and the separation rate of hemoglobin and oxygen is very slow. Therefore, once a person inhales carbon monoxide, oxygen loses the opportunity to bind to hemoglobin, making tissue cells unable to obtain enough oxygen from the blood, causing difficulty in breathing, rapid spasm, coma, cheeks, chest skin and lips are cherry-red. If treatment is not done in time, respiratory depression can be quickly depressed and death.

The lucky thing about this family was that during the siege, there was very little carbonite left. The old man and his daughter-in-law gritted their teeth and were frozen in the outer room, giving their son the only warm opportunity. The inner room space was small and the indoor air was not smooth. As a result, the old man and daughter-in-law who loved to be frozen in the outer room were not seriously injured, but the son in the inner room was poisoned and died of death.

"A person cannot be resurrected after death, so please feel sorry for me!" Chen Ying silently asked Liang Zan to throw away some money and leave this tragic family.

When the cold wind blew outside the house, Chen Ying's head became clear.

In this era, people do not have enough understanding of carbon monoxide poisoning. They usually believe that only carbohydrate is toxic, while charcoal is not toxic. In fact, this is a wrong understanding. Whether it is charcoal or coal, it will not cause harm to the human body when the air is smooth. However, once the air is not circulating and the carbon monoxide content in the indoor air exceeds the standard, it will lead to a tragic tragedy.

No, this tragedy must not happen again. Because carbon monoxide poisoning, generally speaking, the whole family is dead. It is rare for the elderly to spoil their son because they are too doting on their son and let their son enjoy the warmth alone. Moreover, if the whole city is so open, the people have a lot of firewood in their hands. If a tragedy occurs, it will be a big basket.

Of course, at this time, there is no such thing as accountability. Even if there is a tragic situation, it will not be blamed on Chen Ying. However, Chen Ying could not overcome the hurdle in his conscience. Chen Ying returned to the Lingzhou General Administration Office and watched Yang Ze still write and scratch in front of the desk.

Chen Ying told Yang Ze about the tragedy that happened to this elderly family.

Yang Ze said: "General Manager Chen, I will order the Lingzhou City Ya and General Manager's Office clerks to inform them from the whole city from door to door!"

"Precautions to prevent charcoal poisoning are only used to treat the symptoms, but not the root cause!"

"Then how can we treat the root cause?" Yang Ze really couldn't figure out. This charcoal poison is colorless and odorless, and it is hard to prevent it. How can we treat the root cause?

In the era when Chen Ying lived, there was not a lack of carbon monoxide poisoning, but it was definitely not much, and the proportion was very low. However, in this era, due to insufficient cognition, the accident rate was much higher.

Chen Ying thought about it. In later winter, there were not only heating in the north, but also two individual heating methods for families: kang and fire wall. Kang mainly appeared in the northeast, while fire wall appeared in the northwest and Xinjiang regions. Of course, with the replacement of the warm-up and natural gas heating methods, this primitive and backward heating method is slowly withdrawing from the stage of history.

Compared with natural gas heating and concentrated heating, Chen Ying has not yet been able to solve these two methods. Among them, Chen Ying has no way to solve the problem of water pipelines and pressure. However, the firewall and fire pit are too simple.

Chen Ying took the pen from Yang Ze and drew out the figures of the fire wall and fire pit of the later generations on the desk. He pointed to the figure and said: "Whether it is a fire kang or a fire wall, it is very simple. Any mason can dry it when he looks at the drawings. Just pay attention to the chimney and smoke exhaust. Of course, you must pay attention to the open flames and smoke, and you must not appear indoors."

Yang Ze said: "I didn't expect that General Manager Chen is not only a master of military tactics, but also a mixed-class man!"

"Uh" Chen Ying thought that this method of building firewalls and fire pits should be considered common sense knowledge. When he saw Yang, he thought that because the way of dissemination of knowledge was restricted by the times, the common sense knowledge in later generations was also a great topic here. Although heating has a history of thousands of years on this land, a very small number of people are still proficient in heating supply.

Yang Ze was also a decisive act. When Chen Ying raised this question, he immediately ordered three yamen runners and officials from various yamen to take action separately. The key is that Chen Ying himself was a civilian and craftsman in the army, and took the lead in renovating the Lingzhou General Administration Office.

In fact, it is really as Chen Ying said, extremely simple. Chen Ying lives in the front office of the Lingzhou General Administration. The hall has been built for a while. Following the old wall of the front hall, within one and a half feet of the wall, he built a single wall with glutinous rice soup and mud. This fire wall made two holes in the outer wall, one for smoke and the other for burning materials.

In less than half an hour, more than a dozen craftsmen built this fire wall and then took it naturally and put it in charcoal.

Seeing that the craftsman was about to use charcoal, Chen Ying said, "No charcoal, just use charcoal!"

A craftsman kindly advised: "Carbonite is poisonous!"

"When something goes wrong, I will take care of it myself!"

"But!"

"What are you talking about!"

In fact, Chen Ying was not the only way to save money. He had an emotion that ordinary people could not imagine in this era. However, due to the severe loss of soil and water in the middle and upper reaches, a large amount of mud and sand were caused, causing the Yellow River to flood from time to time.

Chen Ying vaguely knew that in the late Tang Dynasty and early Song Dynasty, the ecological balance in the middle and upper reaches of the Yellow River was completely destroyed. If people change their habit of replacing charcoal with charcoal and reducing the use of wood, they can leave a blue sky for future generations.

The craftsmen really did not dare to disobey Chen Ying's wishes, so they had to follow Chen Ying's wishes.

After working hard until midnight, Chen Ying felt exhausted. Then he was about to go back to rest. When he arrived at the bedroom, Chen Ying was stunned. A woman appeared in his bedroom. The woman was plump and sat there, with her waist soft. Her bulging breasts stretched out the light green spring shirt, forming a perfect and attractive curve. Her face was extremely delicate under the light and her eyes were particularly charming. Seeing Chen Ying come back, she stood up, yawned, and shouted in her mouth: "I'm the general's clothes!"
