In addition to the steel composition of the 645 artillery itself, its overall performance has fallen behind, and it is not suitable for modern operations, and at the same time, the Xian army is designing a new generation of artillery, and the gradual elimination and replacement of the 645 artillery is a matter of time.

The 645 upgraded and modified after-loading gun is only a transitional stage, and when the new model begins to be equipped, the artillery of the Jin Kingdom will open up a two-generation gap, and it is still not a threat to the Xian army.

Compared with the breech artillery, which was not equipped much with the Jin army, the threat of guns and bullets to the Xian army was greater at present and even for a long time in the future, and the export of guns and bullets should be extremely cautious.

The outdated machine tools and equipment that Ji Feng bought from Bailiyan soon became the "equipment manufacturing center" of Liang State after the war, and Ji Feng also suddenly realized that Bailiyan made so many machine tools and equipment, and manufacturing industrial products to make money was only one of them, and the production of guns and ammunition armed forces was the ultimate goal.

So in 653, not long after the main force of Yuke moved to defend Liang State, Liang Tianzi got two types of guns from Yuke for imitation, and tried to imitate machine tools on the basis of the previous purchase of machine tools.

However, knives, steel and even bullets still need to be purchased from Bailiyan, and their imitation is just a superficial imitation of the cat and the tiger, without the production capacity of bullets, the more guns are made, the heavier the burden.

In the following days, there were violent deaths of the epidemic in the places where refugees gathered in Qingtian, Sangnan, and Sangbei counties, and the total number of people increased sharply to more than 3,600 people, distributed in 17 villages and counties in the three counties, and became a trend of rapid spread.

Since the phone did not receive from the other princes and counties, he did not know the news of the outbreak of the disease in the other counties of the eldest grandson.

On May 24, samples of the disease strain collected from Gujia Village were stored in a low-temperature biochemical sealed carrying box and delivered to the Taoli Vaccine Cultivation Center, which was expanded four years ago at the request of the storm and divided into two, one south and one north, separated by 150 miles.

The North Institute is a newly built biological center, specializing in the study of pathogenic microorganisms, and the South Institute is specialized in vaccine research and production, providing technical support and data basis for the production of Xuanyun and Ruitian pharmaceutical vaccines.

Although Ranlan has the ability to systematically analyze, Bailiyan will still require researchers to find their own technical research paths and accumulate experimental experience and data.

Indirectly use the information provided by the Wild Tide to give them some guidance, not to ready-made.

The diseased plant was delivered to the North Institute at dusk on the afternoon of the 24th, but Bailiyan got bad news that night.

"According to the results of preliminary testing, this is an acute pneumonia and the causative agent is chlamydia."

"Chlamydia acute pneumonia?" Bai Liyan was taken aback, and he hurriedly said: "Acute pneumonia mostly occurs in infants and young children under the age of ten, and now adults, children, and the elderly are infected on a large scale, and the rapid onset and high mortality rate have exceeded the scope of acute pneumonia, what other sources of pathogenesis?" ”

"At present, it is true that the cause is acute pneumonia, but this does not seem to be ordinary acute pneumonia, once this pneumonia occurs, it will form tuberculosis within three to five days, and at the same time induce acute encephalitis, so it is not acute pneumonia itself that kills the host, it is acute encephalitis."

"You're saying that this acute pneumonia can quickly induce tuberculosis and start with acute encephalitis."

"Yes, it's a very powerful source of chlamydia, with an incubation period of three to four months. Unlike tuberculosis, tuberculosis carriers usually do not develop the disease immediately, but only after the body's immunity is weakened, so tuberculosis is more common in frailty and malnutrition, and the pathogen with a long incubation period can be dormant for decades.

However, this kind of pneumonia is eaten by all ages, as long as it is infected, 80 percent will develop the disease, and tuberculosis will form rapidly in three to five days, but before that, 57 percent of patients will die of acute encephalitis first, and the remaining patients who do not develop acute encephalitis or carry acute encephalitis will eventually die of tuberculosis. So once the infection spreads, the consequences are very serious.

At the rate of spread in the past few days and the rate of population movement in Xianguo, it will spread to Shanling within half a year, and in another 20 days to a month, more than 10 percent of the population in Qingtian, Sangnan, and Sangbei counties will die of the disease, and then it will spread rapidly at a rate of 172 percent per month.

In addition to this, this acute encephalitis can be transmitted through the air, water, indirectly, directly, and is almost uncontrollable. ”

"How can there be such a powerful pathogen, before this, I have never heard of this kind of plague in the Central Plains, even if it is malaria, cholera, and plague, it does not have such a high fatality rate and infection rate."

"It is true, judging from the pathogenic data that have been collected before, there is no similarity in the core settlement formula of this acute pneumonia strain, and there is no comparable original mutation reverse morphology, and the affinity with the core solution formula of the human Central Plains is very high.

The reminder of the wild wave surprised Bailiyan:

"You mean, the Armpit Man brought it from the Northern Hemisphere!"

"Although axillary people will not be infected with most human diseases, this acute pneumonia cannot survive in their bodies, and the survival rate in nature will not exceed two months.

Therefore, it should be that they deliberately fed the disease strain to humans, or put water sources and then infected humans, taking advantage of the mentality of human beings to escape the war and the long incubation period of the pathogen to spread the pathogen to inland areas.

If one-third of the population flow data of Xianguo is downgraded to simulation, the pathogen will spread to all corners of the Central Plains after eight years and nine months, and fully spread to Jinxuedi itself after thirteen years, killing one-fifth of the population after six years, killing 65 percent of the remaining population after eight years, and ...... after 15 years."

"Enough!" Bai Liyan was enraged: "These dog mongrels who have lost their humanity and conscience, they are unforgivable, unforgivable!" ”

"But at this point, no amount of swear words you say. The communication of Changsun Kingdom in the north is extremely backward, and the local information is very closed, coupled with the loss of the fleeing population, which has aggravated the difficulty of communication and information blockage, and it should not have attracted the attention of the local government, but it is too late to attract attention.

Nearly 4,000 people died in the three counties of Qingtian, Sangnan and Sangbei, and the number of infected people was at least ten times, and the carriers were ten times that of the infected people. ”

"I've said enough, don't say any more. Tell me, is there any way to treat this acute pneumonia, and are the current antibiotics effective? ”

"Judging from the current data results, the replication and division of pathogens in the body can be effectively prevented by oxygen inhalation, or the dual treatment of Guardian No. 2 and No. 6 antibiotics can be cured."

"Isn't there any other universal cure, herbal formulas?"

"I'm sorry, but the simple herbal formula can't quickly stop the spread and proliferation of this acute pneumonia in the body, and it requires the injection of a variety of extracts to treat it, but it also takes time to produce, but it seems that with the current reserves of antibiotics and refunciferin, it is far from enough for tens of millions of people to do a dose unit.

Because it is a foreign pathogen brought in by geographical isolation, some mutations occur after affinity with the Central Plains people and local microorganisms, maybe it is a good mutation, the infection rate of the pathogen will decrease, maybe it will worsen, the onset will be faster and the mortality rate will be higher.

At the same time, the body's immune system will also resist and adapt, so the damage of the strain may also be reduced as the spread of the disease.

I recommend that the infected areas be immediately cordoned, the water sources should be disinfected, masks should be distributed, and the pathogen should be killed by boiling it in hot water at 93 degrees Celsius for three to five minutes. After entering the summer, the activity of pathogens decreases, and the high temperature weather and ultraviolet rays that last for three or two months can effectively kill pathogens. ”

"What is the probability of mutation for the better?"

"There is too little biological data available in nature to support data modelling. However, by doing a good job of basic epidemic prevention work, the spread can be reduced before the summer. ”
