A handsome little daughter-in-law suddenly came out of the back room, and by the light on the street, Chen Ying found that the little daughter-in-law still had tears on her face, and the little daughter-in-law glanced at Chen Ying timidly, Chen Ying also found that the little daughter-in-law still had tears on her face, and it should be her who choked up just now.

The little daughter-in-law looked at Chen Ying, Ryazan and other Tang Army soldiers, and hurriedly retreated back to the back room.

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

Actually, this can't be blamed on this little daughter-in-law's heart. At the end of the Sui Dynasty, the thirty-six roads were against the king, the seventy-two roads were dusty, and there were more than one million soldiers and horses across the country, but the soldiers and bandits were really not clear.

Chen Ying didn't care too much.

The old man said: "There is meat, but no one has it, what is the use of meat?" ”

Chen Ying was puzzled, Ryazan took a torch from his guard, and the torch illuminated the small room as if it were daylight, and at this moment, Chen Ying suddenly found that there was a corpse lying in the hall.

The corpse did not look very old, Mo was in his twenties, and his face was blue and purple.

Seeing this corpse, Chen Ying became puzzled.

"Master Jun doesn't need to look at it, it's charcoal poison, it's all fate!" The old man's tone was cold, without any human emotion. Thinking about losing a child in old age is a very big blow to the elderly.

The so-called charcoal poison is what later generations called carbon monoxide poisoning in medicine. The binding capacity of hemoglobin to carbon monoxide in the blood is more than 200 times stronger than that of oxygen, and the separation of hemoglobin from oxygen is very slow. Therefore, once a person inhales carbon monoxide, oxygen loses the opportunity to combine with hemoglobin, so that tissue cells can not obtain enough oxygen from the blood, resulting in difficulty in breathing, rapid convulsions, coma, cheeks, chest skin and lips are cherry red, if the treatment is not timely, respiratory depression and death can be quickly caused.

The family's luck was that they had very little charcoal saved during the siege, and the old man and his daughter-in-law, gritting their teeth and freezing in the outhouse, gave their son the only chance to be warm. The inner space is small and the indoor air is not smooth, so the old man and his daughter-in-law who love to freeze in the outhouse are fine, but the son in the inner room is poisoned and died.

"People can't be resurrected after death, and the old people still ask for condolences!" Chen Ying silently asked Ryazan to drop some money and leave this tragic family.

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

In this era, people do not have enough understanding of carbon monoxide poisoning, usually think that only charcoal is toxic to coal, and charcoal is not toxic, in fact, this is a wrong perception, charcoal or coal, in the case of smooth air, will not cause harm to the human body, but once the air is not circulated, the carbon monoxide content of indoor air exceeds the standard, then it will cause a tragic tragedy.

No, this tragedy must not be allowed to happen again. Because of carbon monoxide poisoning, generally speaking, the whole family is killed, and it is too rare for an old man to let his son enjoy the warmth alone because he dotes on his son too much. Moreover, the whole city was so open that the people had a large amount of firewood in their hands, and in case of a tragedy, it would be a big basket.

Of course, at this time, there is no accountability, and even if there is a tragedy, Chen Ying cannot be blamed. However, Chen Ying couldn't pass the hurdle on his conscience. Chen Ying returned to the Lingzhou Governor's Mansion and watched Yang Ze still write and draw in front of the bookcase.

Chen Yingjiang encountered the tragedy of this old man's family and told Yang Zeyi.

Yang Zedao: "Chief Manager Chen, I will order the Lingzhou City Government and the Governor's Office Scribe to notify them door to door in the whole city!" ”

"Pay attention to prevent charcoal poisoning, it is only a symptom, but not a cure!"

"So how can we cure the root cause?" Yang Ze really can't figure it out, this charcoal poison is colorless and tasteless, and it can't be prevented, how can it be cured?

In the era in which Chen Ying lived, carbon monoxide poisoning was not uncommon, but it was definitely not much, and the proportion was very low. However, in this day and age, the accident rate is much higher due to insufficient awareness.

Chen Ying thought about it, in the future winter to prevent heating, the north not only has heating, but also two ways of individual family heating, the fire kang and the fire wall. The fire kang is mainly found in the northeast, while the fire wall is found in the northwest and Xinjiang regions. Of course, with the replacement of the first heating 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 centralized heating, Chen Ying has not been able to solve these two methods, including the problem of light water pipeline and pressure, Chen Ying has no way to solve it. But the walls of fire and the fire pits are so simple.

Chen Ying took the pen from Yang Ze's hand and drew the graphics of the fire wall and fire pit in later generations on the bookcase. Pointing to the figure, he said: "Whether it is a fire kang or a fire wall, it is very simple, and any mason can do it by looking at the drawings." As long as you pay attention to the chimney and smoke exhaust, of course, you must pay attention to the open flame and open smoke, which must not appear indoors. ”

Yang Zedao: "I didn't expect that Manager Chen is not only a master of the art of war, but also a miscellaneous family!" ”

"Uh" Chen Ying also thought that this method of building fire walls and fire pits should be regarded as common-sense knowledge, but Yang Ze was quite surprised, thinking that at this time, due to the restrictions of the times in the transmission of knowledge, no matter how common sense knowledge is in later generations, it is also a university question here. Although heating has been practiced in this land for thousands of years, it is only a handful of people who are truly proficient in heating supply.

Yang was also a resolute person, and when Chen Ying raised this issue, regardless of the fact that today was Chinese New Year's Eve, he immediately ordered the three classes of servants and the officials of each Yamen to act separately. The key is that Chen Ying himself is a civilian man and a craftsman in the army, and he took the lead in transforming the Lingzhou Governor's Mansion.

In fact, it is really as Chen Ying said, it is extremely simple. Chen Ying lives in the front office of the Lingzhou Governor's Mansion, the hall has been built for some years, along the old wall of the front hall, within one and a half feet of the wall, with glutinous rice soup and mud, build a single wall, this fire wall in the outer wall to make two holes, one to keep the smoke, one to fill in the burning material.

It took less than half an hour for more than a dozen craftsmen to build this wall of fire. Then go with the flow and put in the charcoal.

Seeing that the craftsman was preparing to use charcoal, Chen Ying said: "Don't use charcoal, use charcoal!" ”

A craftsman kindly advised: "Charcoal is poisonous!" ”

"If something goes wrong, Mr. Ben will take care of it himself!"

"But!"

"What nonsense!"

Chen Ying is actually not good at saving money, for the mother river of China, he has emotions that ordinary people in this era can hardly imagine, but due to the serious erosion of water and soil in the middle and upper reaches, a large amount of sediment has been caused, making the Yellow River flood from time to time.

Chen Ying vaguely knew that at the end of the Tang Dynasty and the beginning of the Song Dynasty, the ecological balance of the middle and upper reaches of the Yellow River was completely destroyed. If in this era, people's habit of replacing charcoal with charcoal and reducing the use of wood can leave a blue sky for future generations.

The craftsmen really didn't dare to disobey Chen Ying's intentions, so they had to follow Chen Ying's intentions.

After working until the middle of the night, Chen Ying felt exhausted. Then I was ready to go back to rest. When he came to the bedroom, Chen Ying was stunned. I saw a woman appear in his bedroom, this woman was plump, sitting there, with a soft waist, and a high bulging chest that held up the light green spring shirt, forming a perfect and attractive curve; That face was extremely delicate under the lamp, and her eyes were extraordinarily clear, seeing Chen Ying come back, she stood up, yawned, and exclaimed: "The slave is the general's wide clothes!" ”

Before twelve o'clock, there should be a chapter that can be coded.
