A thin layer of grass ash was lightly spread on the charcoal brazier, and in an instant, the flames in the brazier were annihilated.

Everyone's hearts tightened, and they immediately knew that charcoal poison had probably begun to occur.

"Your Majesty! Please evacuate this house. Hua Yuan stepped forward to persuade.

Li Shimin nodded, and took the lead in walking out of the conference room, and a group of people from hundreds of families walked out one after another.

Merton walked to the end, waited for everyone to walk out of the conference room, and then slammed everyone out.

"Merton, what are you doing?" Hua Yuan was shocked and wanted to open the door, but felt that Merton had blocked the door from the inside.

"Charcoal poison is colorless and odorless, only people in the house can detect it, the kid is young, strong and can bear it." In the conference room, Merton's voice could be heard.

Cheng Yanjin shouted: "Your kid is weak and can't help the wind, if you really want to test the poison or come silently, you come out and replace him." ”

Cheng Chumo's heart sank suddenly, you are really your father, that is an invisible charcoal poison that kills people, you are not afraid of white-haired people sending black-haired people.

Merton pondered for a moment, opened the door of the conference room, and shouted with his head exposed: "Each person reacts differently to charcoal poison, and many people test it, give it a try, different people's carbon poison reactions also have a certain medical value." ”

"Uh-uh!" Suddenly, Qin Huaiyu and the three of them wanted to strangle Merton.

They were sure that Merton didn't want to suffer alone, so he dragged the three of them into the water.

In desperation, in full view of everyone, Merton dared to risk his life, and it would be too embarrassing for them to admit it, so he had to enter the conference room directly.

"Merton, I remember you!" Cheng Chumo passed by Merton's side, punched him hard, and said hatefully.

Qin Huaiyu and the three of them rushed in, and the door of the conference room was closed again.

Qin Huaiyu and the three of them sat in the position of the hundred families just now, they didn't feel honored at all, they all stared nervously at the dark red charcoal fire, they heard it very clearly just now, this is colorless and tasteless, killing people from invisible poisonous gas.

Qin Huaiyu fidgeted, and suddenly covered his chest and said, "Merton, I suddenly feel very uncomfortable, it shouldn't be poisoning!" ”

Merton glared at him angrily and said, "It's only been twenty breaths since I entered the house, and if I could be poisoned so quickly, there wouldn't have been so many charcoal poison incidents." ”

"Besides, there are people outside, and we are still in the Ink Hospital, even if we are poisoned, we can still save you."

"Didn't you say there was no cure?" Yu Chi Baolin muttered.

Merton patiently explained: "The gate is not locked, and if I wait for poisoning, it will naturally not be too late to go out again." ”

"I'd rather go to the battlefield and fight than face such a colorless and odorless poisonous gas." Cheng Chumo sighed.

Merton was about to say more, when he suddenly felt a wave of nausea, and then looked at Qin Huaiyu and the three of them also frowned, the charcoal poison had already begun to work.

The four of them looked at each other and nodded affirmatively.

"Bang bang bang!" Merton slammed on the door of the conference room.

"What's wrong?" Cheng Biting Jin's loud voice came from outside the door.

Merton replied in a loud voice: "All four of us have begun to feel nauseous and have a slight poisoning. It can be confirmed that this is charcoal poisoning. ”

Everyone breathed a sigh of relief when they heard this, knowing where the charcoal poison came from, and they would have something to watch out for in the future.

Hua Lao and Sun Simiao were just about to pick up the information to prepare for the record, but they heard the sound of brushing, Yan Tuizhi was holding a pencil and writing a special book, the first hundred schools of thought, they found the origin of charcoal poison, this must be a deed that can be recorded in history!

"That's it! Now that it's confirmed, let's wait for it to come out! Outside the room, Hua Lao hurriedly said.

Merton was about to agree, but suddenly remembered that Cheng Biting Jin said that he was weak just now, turned his head and saw the strong bodies of the three people, gritted his teeth and said: "The charcoal poison in the body is fine for a short time, I can take the opportunity to experiment with the reaction of different people to the charcoal poison, and it is not too late to go out after anyone can't hold on." ”

Qin Huaiyu and the three of them all wanted to scold their mother in their hearts, but after glancing at each other, they didn't think they were the weakest, snorted coldly, and acquiesced in Merton's words.

"Yes, the four of them have the courage to take responsibility for the people of my Tang Dynasty, and they are indeed manufacturable materials!" Su Linong sighed.

Li Shimin and a group of people from hundreds of schools nodded one after another, only Kong Yingda was very tired in his heart, these four people did not cause much trouble in Guozijian, they were all problem students, and now they have turned around and become a good boy praised by everyone, such a change in painting style is too fast!

Cheng Yanjin didn't care about this, and when he heard everyone praise his son, his old face smiled like a chrysanthemum.

In the conference room, the four of Merton sat opposite each other, one by one, they endured the discomfort in their hearts, and sat with big eyes, the door was not far away, and it could be opened as long as they walked over.

However, none of the four of them were willing to take the initiative to admit defeat and be the first to open the door.

Suddenly, Merton retched, and suddenly like a chain reaction, the four of them rushed to the door in unison.

"Bang!"

The door of the conference room was opened heavily, and the four of them crawled in a hurry, and ran to the open space to vomit, frantically absorbing the newly selected air.

After a long time, the four of them poured three cups of tea sugar tea in a row, and then they felt a little better.

"In a quarter of an hour, the danger of charcoal poison is so violent." Sun Simiao saw the four of them sitting there weakly, and sighed again and again.

"Vomiting, nausea, weakness, there is no difference between the strength of the body after poisoning.

Hua Yuan observed the four people on the side and recorded the symptoms of the four people.

Yan Tuizhi was not to be outdone, holding the pen and recording non-stop, Cheng Yanjin behind him looked at it with a smile, obviously extremely satisfied.

The doors and windows of the conference room were opened, and the ashes in the charcoal brazier were removed, and after a while, the charcoal brazier re-ignited the cyan flame.

Once again, the crowd returned to their places.

"So the charcoal poison has been found." Li Shimin said in a deep voice.

Sun Simiao nodded: "Wood charcoal is not poisonous, and even charcoal burning is not poisonous, only by covering up the charcoal and prolonging its burning time will charcoal poison be produced." ”

"And it's extremely violent!" Sun Simiao added.

Han Zheng suddenly got up and saluted Li Shimin: "Since the cause has been found, please ask Your Majesty to tell the world the cause of the charcoal poison and warn the world." ”

Li Shimin nodded approvingly and said: "However, the winter in the north is very cold, and the people have difficulty at night in winter, I am afraid that the people will take risks knowing that there may be charcoal poison." ”

Su Lingnong nodded: "If you burn charcoal directly, I'm afraid it will be burned out in less than half the night, and the cost of adding charcoal in the middle of the night is too large, and of course it will be difficult for the people to bear it." ”

"Opening half a window at night can also effectively prevent charcoal poisoning." Hua Lao said.

Han Zheng shook his head and said, "It is easy to enter the thieves when you open the doors and windows, and I am afraid that it will be difficult for the people to accept it." ”

He rejected this proposal from the perspective of Legalism, there were no burglar-proof windows in this era, and opening the windows was equivalent to leaving a door for thieves.

All of a sudden, everyone knew the harm of charcoal poisoning, but there was nothing to be done, and there was no good way to solve it.

And when everyone was at a loss, a voice suddenly said: "I have a skill that can solve the harm of charcoal poison for Your Majesty,"
