Li forgot to ask someone to light a bonfire.

After the campfire was lit, he asked people to throw a lot of wet wood into the campfire. After the wet wood was licked by the fire, smoke billowed out immediately.

Li forgets to worry and throws the mask to Zhechong Duwei and two Guoyi school captains: "put on the mask, and then stand in the thick smoke to try the effect."

He was just fooling the Duwei and using the mask with activated carbon made by the beautiful boss as a gas mask.

For later medical masks, the middle filter layer is melt blown cloth, which can effectively filter the virus in the air. But this kind of high-tech product can't be made by Li forgetful and Su Changqing in Datang.

As for masks mixed with activated carbon, strictly speaking, they are not suitable for medical protection, but for adsorbing organic gas, odor and toxic dust.

But in Datang, it is already the best protective equipment.

Activated carbon mask can effectively absorb harmful gases such as carbon monoxide. Naturally, it can also be used as a gas mask.

The Douwei and the two captains of Guoyi put on their masks suspiciously, followed Li's instructions and walked into the thick smoke.

It has to be said that the activated carbon mask is absolutely effective for the filtering effect of smoke.

The three of them, wearing masks, stood in the thick smoke. Although they couldn't open their eyes because of the smoke, they didn't feel difficult to breathe at all.

This discovery surprised the three people. They were finally convinced of what Li forgetful had said before.

They are old soldiers. Naturally, they know that people can't breathe in this thick smoke. So it seems that this mask is really a "treasure of the immortal family".

With such confidence, nearly a thousand soldiers of Zhechong Prefecture in Xuzhou, led by the Duwei of Zhechong, all wore masks, rushed to the county seat of Yanling County and began to implement Li forgetful's blockade.

Zhechong Du Wei ordered people to take lime and drew a white line on the ground with lime outside the city gate of Yanling County.

"Listen, anyone who dares to cross this line without permission can be killed directly. Do you understand?"

"Promise!" the soldiers slapped their blades on the ground, punched their right hands in front of their chest, and shouted in unison.

This momentum immediately forced a group of officials in Yanling County, as well as the people in the city, subconsciously retreated a few steps.

However, there are still people who do not believe in evil.

The magistrate of Yanling County is an old man in his 60s with white hair and beard.

He brushed the dust off his official clothes and looked disdainful: "I don't believe it. Do you dare to kill the officials of the court? I'm going to Changzhi county to ask you today. Who ordered you to act like this? I don't believe it..."

Yanling County Magistrate said as he walked towards the white line, raised his feet and stepped out.

He took two steps out of the white line drawn with lime, but saw a feather arrow coming through the air with a whoosh and directly inserted into the county magistrate's chest.

The county magistrate was stunned on his face. He looked up not far away. He was still holding a strong bow in his hand. Duwei trembled and raised his hand to point at him, but he couldn't say a word. He fell to the ground directly. His body twitched a few times, and there was no more movement.

Seeing that the people in the Zhechong mansion actually dared to kill, and it was the imperial court commander who killed them, no one doubted the words of the soldiers before.

Yanling County Magistrate was pale and trembling like chaff. He stared at the fallen county magistrate with a look of panic.

In any case, he thought that such a thing would happen.

"Wait... Wait..."

"Wait a fart! Listen, Hou of Huxian county has ordered that Yanling County immediately start cleaning and transporting garbage and sewage dirt. All rats, mosquitoes and flies have to be strangled and put out! Repeat the ban, no one is allowed to drink raw water, no..."

Duweisi didn't show mercy to the Yanling County Magistrate, directly drank violently, interrupted him, and read out Li forgetful's order.

No wonder he just shot the county magistrate.

Naturally, the county magistrate was not to die of sin, but before they set out to Yanling County, Li forgetful had repeatedly told that no one, including all the officials of Yanling County, was allowed to enter and leave Yanling County.

"Lord Hou, if the Ming government of Yanling County wants to break out by force..."

"Shoot to death!" Li forgot to worry, biting his teeth, and replied with a slightly ferocious expression.

No wonder Li forgets to be worried. If not, once the epidemic can not be controlled in Yanling County and spread everywhere, it will be an unimaginable loss.

This is the arrow that Zhezhong Duwei shot and killed the mayor of Yanling County, which defeated everyone's last fluke from top to bottom.

The magistrate of Yanling County didn't dare to say anything more about it. He could only lead a group of officials and yamen back, and finally began to seriously implement the health bans issued by Li forgetful.

Fortunately, Su Changqing shipped a lot of masks this time. Within a few days, she called all the female workers and worked day and night to get tens of thousands of masks out.

These masks were also sent to Yanling County by the government soldiers. After teaching them how to wear them, they forced everyone to wear masks at any time.

After two days of hard work, the magistrate of Yanling County finally made up for the past, led a group of Yamen servants, drove the fangzheng of each lane, and forced the people and victims to clean up Yanling County from beginning to end.

The filthy things cleaned up were transported out of the county under the supervision of the government soldiers, dug pits and buried, and a large amount of lime was sprinkled inside for disinfection.

As for Yanling County, the air is also filled with the smell of lime water.

Li Qieyou, Su Changqing and the dandies had already arrived outside Yanling City, but they were not in a hurry to enter the city.

No wonder Li forgets worry and is timid. With today's epidemic prevention level, he can't be too careful.

However, he still sent the medical workers recruited from Changzhi county to put on masks and go into the city to check the situation of the patients.

Liu Shenwei also volunteered, put on a mask and entered Yanling County with the medical workers.

Half a day later, Liu Shenwei returned from Yanling County.

After soaking in lime water and spraying it with alcohol from beginning to end, Liu Shenwei sat in front of Li forgetful.

"Ziyou, the trouble is big, it's a big head plague!" Liu Shenwei's fingers still trembled until this time, and his hand holding the tea cup kept trembling.

"Big head plague?" Li forgets to worry about something inexplicably. What infectious disease is this? I haven't heard of this disease in future generations.

"Yes, there's nothing wrong with big head plague. I've seen those patients with swollen neck, coughing and hematemesis. Some are also called pimple plague."

Li Qieyou still didn't understand. Looking back carefully, did later generations have this disease?

Immediately, a paragraph of words popped out of his mind, "the summer and autumn epidemic, a doll gave birth to a fat bulge and died a few moments later, which is called pimple plague. All people suffer from this disease. In the spring, there are people who vomit blood, who also die for half a day, or several people in a family."

Li's body could not help trembling

Plague!
