The order handed down by Li forgetful worry is the basic knowledge of epidemic prevention known to all future generations, but it is difficult for the people of Tang Dynasty.

The boatman who was kicked over by him, although he said he was guilty, he felt that Huxian Hou was too lenient.

Don't these boatmans live like this all the time?

Who has the time to boil water when sailing on weekdays?

In his opinion, it's just Li forget worry, a noble man who has nothing to do, even how they drink and eat.

Of course, the boatman didn't dare to say these words. Not only did he think so, but there were complaints in the whole fleet after Li forgetful's order was passed on.

After discussing with the beauty boss, Li forgot to worry, but immediately issued stricter orders.

It is forbidden to drink raw water, eat unclean food, urinate and spit everywhere... A series of detailed regulations make people complain.

Not to mention that the boatman and the forbidden army don't understand, even the dandies, Li Chengqian, Li Tai and others don't understand why Li forget you issued such an order.

But Li forgot to worry, but he didn't intend to explain.

After all, in this era, except Sun Simiao and Liu Shenwei, because of the existence of microscope, now there is the concept of bacteria, and others don't understand these at all.

He could not slowly explain to the public what bacteria, pathogens and viruses were. He had to take high-pressure measures to force everyone to accept them.

If there is disobedience, the light one will be confined, and the heavy one will be whipped.

Fortunately, as a Marquis of Kaiguo county and a dethroning envoy of Henan Dao, no one dared to listen to his words.

Even if the boatman and the forbidden army complain that Li forgets to worry about many things, they can only honestly obey the orders.

After Li forgets to worry about issuing the order, he looks at Su Changqing again.

"Chang Qing, after dawn, you will take Alfred and go back to Zhengzhou with Li Chengqian, Li Tai and Cheng Chumo and directly back to Chang'an."

Now that Xuzhou may become an epidemic area, Li forget worry, where are you willing to let the beautiful boss take risks with him?

Even when he heard the word "epidemic area", his legs and stomach trembled.

The virus, no matter who he is.

With the current medical conditions of Datang, once you catch those messy viruses, you may have to wait for death except that the penicillin in Sun Simiao's hand has a certain probability to save his life.

If Li Er hadn't made him the dethroning envoy of Henan Dao, he would have ordered someone to turn the bow and go back to Zhengzhou.

It's not that Li forgets his worries and is timid. It's really a human instinct to cherish life.

Su Changqing immediately understood his mind. Her beautiful eyes widened, stared at Li forgetful and said, "if I don't go, you can't drive me away! To face the epidemic, let's face it together. At the beginning, you agreed with me to share life and death in this Datang."

Obviously, women are more emotional than men in the face of such things.

Li forgot with a sad smile: "listen to me, Changqing, you have a reason to go back."

"I don't care. There's no reason why you won't go. Besides, don't forget, I'm different from you. I've passed through Datang and I've been vaccinated for a long time. As for you, you haven't been vaccinated. If you want to go, you'll go. I'll stay and help you with disaster relief."

Su Changqing didn't listen to Li Lianyou at all, and what she said was not wrong at all.

Everyone in future generations has been injected with various vaccines since childhood. Many of the viruses that were the top disaster in Datang, such as smallpox, have long disappeared in future generations.

Li forget worry was naturally moved by the beautiful boss's words. He didn't care whether he would be seen by others on the ship, so he directly reached out and grabbed the sweet shoulder of the beautiful boss.

"Listen to me, Changqing. You must go back to Chang'an city. There's something you need to go back and immediately organize the women workers in the underwear workshop to help me make it."

"What?"

"Mask!"

Su Changqing suddenly realized what he said.

Indeed, in the face of a possible epidemic after a flood, we can't do without protective articles.

Although they can't make medical protective masks in the real sense in Datang, some are better than none.

Masks have existed in China since ancient times.

"Li Shu" records: "cover your mouth, fear gas to touch people."

Marco Polo's travels also wrote, "in the palaces of the Yuan Dynasty, people who offered food covered their mouths and noses with silk cloth, so that they could breathe and do not touch food."

But that kind of silk cloth covering the mouth and nose is actually meaningless. At least it can't defend against the virus.

"Forget your worries. I'm afraid the mask made of cotton doesn't work?" Su Changqing asked suspiciously.

There is nothing wrong with what she said. Future medical masks seem to be made of non-woven fabrics. In fact, there is a filter material in the middle of the mask to block viruses in the air.

Li forget worry in the Tang Dynasty, naturally can not get that kind of filter material, but there is no other way.

"Changqing, do you know activated carbon? Adding activated carbon in the middle of the mask can also block the spread of the virus."

Su Changqing couldn't help nodding when he heard the speech: "this is a good way. It's not difficult to make activated carbon."

"So you must go back to Chang'an City and get someone to start making masks. The sooner you make masks, the safer I will be in Xuzhou."

"But..."

Li forgot to worry and kissed her boss gently on the pretty face. "It's nothing good, but it's settled. You'll go back to Chang'an with Li Chengqian and Li Tai early tomorrow morning. Be good and obedient."

Su Changqing thought for a while, and could only nod silently and promise.

"In addition, you have to help Sun Simiao get more penicillin out as soon as possible and send it to Xuzhou. If there is an epidemic in Xuzhou, I'm afraid only penicillin can save lives."

Li forget worry, this is also a dead horse as a living horse doctor. If there is an epidemic like smallpox, penicillin is useless. He just seeks comfort in his heart.

That night, Li forgot to worry and Su Changqing talked for a long time, and almost didn't sleep all night.

It was not until dawn that Li forgot to worry that someone called Mituo and asked him to escort Li Chengqian and Li Tai back to Chang'an city immediately.

Mito was puzzled and didn't understand what Li forgot.

Li forgot to worry and could only reach his ear and whispered, "after a major disaster, there must be a major epidemic, which must be prevented."

Mito's face suddenly changed. He turned stiffly and looked around at the vast swamps. His body couldn't help shivering.

He immediately understood Li's words. If the epidemic broke out in Xuzhou, who would dare to put the crown prince and his Highness the king of Yue in such a dangerous forbidden area?

"Hou, Hou ye, why don't you withdraw together, or go back to Zhengzhou first?" Mito still has a conscience and thinks of Li forgetting his worries.

Li Qieyou shook his head, looked at the wall of Changzhi county not far away, and dropped a sentence: "I'm the Daozhi envoy of Henan!"
