On March 6th, early in the morning, Ms. Liu from the Women's and Children's Camp came to see her. Ms. Liu said that she had made a lot of masks and there was no place to put them. It would depend on where to put them.

Li Mengxi suddenly realized that he had accidentally forgotten about the mask.

He quickly followed Ms. Liu to the women's and children's camp. After arriving at the women's and children's camp, Li Mengxi looked at the large packages of activated carbon masks that had been packed. Li Mengxi couldn't help but hold his forehead, it's over, something happened.

Activated carbon masks have a shelf life. The ability of activated carbon to absorb impurities is so great that if left unprotected for a period of time, the mask will become contaminated.

Calculating the time, more than ten days have passed since I started looking for someone to make masks. It is estimated that most of the masks have been contaminated.

Li Mengxi realized that he had to quickly find a way to preserve the mask. According to the properties of activated carbon, it is not enough to just leave the mask indoors. It must be placed in a sterile environment that is isolated from the air.

However, under the current conditions, where can I find a place that is sterile and isolated from the air? Should I put it in a jar?

It's okay to put them in jars, but given the size of the jars, how many jars would it take to hold thousands of masks? We have to find a better way.

After thinking about it, Li Mengxi thought of an environment that could isolate the air and be sterile or with few bacteria, and he thought of an earthen kiln.

When burning charcoal, the earth kiln is sealed. After sealing, no air can enter the kiln. The earth kiln is an excellent place to isolate the air.

Furthermore, the production method of the earthen kiln determines that the temperature in the kiln is very high when the kiln is fired. Even if there are bacteria in the kiln originally, after the kiln is fired, there will be no bacteria left.

Li Mengxi thought about how to store masks and other supplies that were afraid of germs. He could find a clean kiln, put the things in, and then seal the kiln.

Having an idea, Li Mengxi immediately rushed to the kiln, asked someone to find out which kiln had been used recently, and then stuffed all the prepared masks into them.

According to Liu, the total number of masks made during this period must be over 100,000.

For more than ten days, an average of 10,000 masks have been produced every day. There are at least a thousand women working in the women's and children's camp. Each person sews ten masks a day, which is almost the number.

As many as 100,000 masks were placed in the kiln, taking up only a small amount of space.

According to Li Mengxi's estimate, a medium-sized earthen kiln can hold tens of millions of masks. In other words, based on three to five masks per capita, the total number of masks needed by hundreds of thousands of people in Julu County can only be

A kiln warehouse is enough.

The kiln was sealed, and after the kiln was sealed, a fire was set up to dry the kiln door. Afraid that if there were any cracks, air could accidentally get in. Li Mengxi had people seal the kiln from top to bottom and then cover it with a layer of mud to seal it tightly.

As safe as possible.

After dealing with the masks, Li Mengxi thought, since the cave is very clean and the cave can be well isolated from the air after being sealed, then besides masks, what else can be put in the cave, food? medicinal materials? fruits?

Li Mengxi had a vague feeling that cave dwellings would be of great use, like cellars in rural areas in later generations, where sweet potatoes and potatoes could be stored for a whole year.

Li Mengxi then went to see the pharmaceutical progress.

After it was discovered that medicine for curing wind and cold could be extracted from willows, the preparation of medicines was large-scale from the beginning because willow materials were extremely easy to obtain, the preparation was extremely convenient, and the extracts were extremely effective.

There are now two to three thousand people in the army who make pharmaceuticals on a daily basis. Every day, vehicles collecting willow branches from outside come and go incessantly. During this time, countless jars of medicinal powder have been prepared.

Li Mengxi deduced that since the extract from willow can be extracted with boiling water and since high temperature will not destroy its medicinal properties, this shows that the nature of this substance is relatively stable.

If the relatively stable medicinal properties are placed in a clean jar that has been sterilized by high-temperature boiling, and then sealed to isolate the air, it must be able to be stored for a long time.

The method of sealing and preserving with wax balls should also be good, but since there is no wax now, it cannot be used.

After the medicine-quenching method was passed on to military doctor Tian Bu, Tian Bu taught the method to other military doctors. During this time, the military medical battalion has produced results.

Medicinal materials in the military were expensive and scarce, and the most abundant medicinal material was licorice. Tian Bu and his colleagues extracted various things from licorice.

Among them, the licorice extracted with alcohol has the strongest taste and is suspected to be the most powerful extract.

However, because the medicinal effect of licorice is mild and its therapeutic effect is not obvious, it is difficult to collect data when testing the medicine.

According to Tian Bu and others, licorice is good at treating symptoms of accumulated heat such as sore throat, blood stasis, and unclear phlegm.

Throat symptoms are generally mild and will get better on their own without treatment. Furthermore, throat symptoms are very uncommon, unlike wind and cold that occur every once in a while.

In summary, it is difficult to test licorice extract.

Li Mengxi listened to Tian Bu's story for a while, and he understood clearly that there was a shortage of patients, and there was a shortage of patients with sore throats.

Li Mengxi thought about it and gave Tian Bu an idea. Since it is difficult to find patients, he should create patients. Since there are few patients with sore throat, he should see what foods can make his throat sore. In this way, he can eat the right medicine.

The disease comes out and the patient is there.

And if you feel that the symptoms are mild and the effect of the medicine is not obvious, it is easier to take more, which will make the symptoms more severe.

The idea given by Li Mengxi was very clever and very good. Tian Bu and others thought it made sense. A group of military doctors discussed how to eat something spicy and hot to test the medicine on themselves.

Seeing the lively conversation among the military doctors, Li Mengxi left the military medical camp. As he was leaving, he scooped up a spoonful of licorice powder and tasted it. After taking a sip, the astringent and bitter taste went straight into his skull, and Li Mengxi spat it out.

Tian Bu and other military doctors had superb medical skills and were all familiar with pharmacology. After everyone discussed Li Mengxi's suggestion, every one of the military doctors in the battalion was ready to participate in the trial of the medicine.

Tian Bu collected some pepper seeds, pepper leaves, ginger, fennel and other things from everywhere, and each person got two taels. A group of military medical battalions took these pepper, ginger and fennel and chewed them with frowns.

Chew pepper seeds dryly, chew them, and then swallow them slowly. Military doctors are all ruthless people.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The military doctors are so good at medicine, they know pharmacology so clearly, and they have chosen the right things. This person drank two taels of peppercorns, and before the next day, there were all the military doctors in the camp.

One or two of the voices were hoarse.

When people went to the military doctors for treatment, they found that the military doctors were so hoarse that they could not speak. The patients were extremely surprised.

Tian Bu felt the consequences of chewing two taels of raw peppercorns. His tongue was numb, and his throat hurt when he swallowed, as if he had been cut by a knife.

Everyone made an appointment to wait overnight and wait until tomorrow for the effect of the medicine (disease) to stabilize. Tomorrow, we will start testing the medicine and the efficacy of licorice powder.

According to the test, some people take medicine, while others have to not take medicine. Tian Bu leads by example. He voluntarily entered the group that does not take medicine. If he does not take medicine, he will have to endure it. It is conceivable that Tian Bu will have a difficult time in the future.

——

In Julu City, everything is as usual, and it has not changed at all because of Liu Bei's departure.

He had been following Zuo Feng for three or four days since Liu Bei led his troops out of Julu.

Liu Bei has fully understood how hateful the traitor Zuo Feng is.

On the road, Zuo Feng brought several vehicles filled with money. The vehicles were so loaded with money that they were too heavy to pull. The entire team was dragged slowly by these vehicles.

As a party involved, Zuo Feng had no idea that soldiers were valuable and had speed, and he had no idea that it was slowing down the army's journey.

Liu Bei was worried about the war and wanted to go to Zuo Feng several times to persuade him to load his money into separate trucks so that he could go faster. However, Liu Bei couldn't help but wanted to question Zuo Feng, but Zhang Fei always came out to stop him.

Zhang Fei warned, "Brother, don't waste Xi'er's hard work. Why bother messing with a villain like Zuo Feng? One bite from the thief will penetrate three points to the bone. Just be patient."

Liu Bei remembered how the military advisor had humbled himself to please Zuo Feng before setting off. He couldn't bear to ruin the military advisor's hard work, so Liu Bei sighed and could only bear it.

The team continued to march, moving slowly, even slower than the Yellow Turbans.

Zuo Feng and his entourage came from Luoyang as envoys. They have excellent chariots and horses. Liu Bei has three thousand troops and horses, and ample logistics. The two groups of troops join together. Logically speaking, it will not be too slow in any case.

As a result, it moves as slowly as a turtle.

The whole problem lies in those carts of money.

When setting out a few days ago, Li Mengxi deliberately picked the largest vehicle in the army and used this largest vehicle to carry money. The larger the vehicle, the more money it could hold, so it was extremely heavy. Not only that, Li Mengxi specially took a

The wheels of the auxiliary car were replaced. Of course, the small wheels can't run fast.

Adding up the two, the car is very heavy, and the wheels are small, so it is naturally slow.

Also, in order to prevent Zuo Feng from taking away the money, Li Mengxi deliberately broke the money into scattered coins when loading the money. In this way, even if Zuo Feng wanted to move it, it would be troublesome to move it.

Li Mengxi's calculation was very cunning. He only used a few carts of money to directly slow down Zuo Feng's progress.

Liu Bei didn't know about Li Mengxi's arrangement. Zhang Fei was a well-connected person. Zhang Fei knew very well why he did this. Zhang Fei knew very well that the later Zuo Feng arrived in Luoyang, the better.

The day before yesterday, the scouts bumped into Jian Yong and his entourage. Zhang Fei quietly walked around the alley and had an interview with Jian Yong. Then, Jian Yong and his entourage hurried forward.

The later Zuo Feng arrives in Luoyang, the longer Jian Yong and his party will spend in Luoyang. In short, the longer the march is delayed, the better, and the slower the better.

Liu Bei didn't know that he was kept in the dark. He didn't know that he repeatedly wanted to remind Zuo Feng to speed up his march. The reason why Zhang Fei repeatedly blocked him was because Zhang Fei did it on purpose.
