One of the slaves' recommendation of Li Wenchang was that he had been exiled to Xiangzhou with his grandfather, and he was not released until a few years later when the imperial court rehabilitated the Jiangxia king. Xiangzhou is a miasma and hot land in Lingnan, and the climate and environment of Nanyang are not too different from those of the slave family. Li Wenchang was exiled to Xiangzhou for several years without being infected with the epidemic, so this time Jun sent him to Nanyang Puluozhong to take charge, didn't Li Wenchang become the most suitable candidate? Originally, the slave family wanted to recommend his brother Li Wenbai, but he commanded the Beihai Iron Cavalry Right Guard, and his people naturally couldn't stay away from Anton. ”

Li Yusi's explanation of the long and long Xian Xin'er is very reasonable, sending a general who lives in the temperate climate of the north all the year round to Nanyang, in case he fails to adapt to the hot and humid climate of the Nanyang and accidentally catches a tropical disease, then it will not be a loss of a general in vain?

"That's right." Xin'er suddenly remembered something: "Jun Xun, speaking of the miasma in Nanyang, the slave family remembered that the news came back from Taiwan a month ago that Xue Maoxun had contracted the disease and was bedridden. ”

"Xue Maoxun is sick and bedridden?"

"The report submitted by the Taiwan Governor's Office said that Xue Maoxun set out from Keelung in mid-September, crossed the mountains to conquer an island in the coastal plain south of Keelung Mountain, and unfortunately contracted illness during the campaign and withdrew his troops."

Xin'er said.

Li Yu was shocked and asked anxiously, "Is there any latest news about Xue Maoxun's condition?" ”

Xin'er shook her head: "Now that the north wind is blowing, it is difficult for Taiwan's ships to go north under the headwind, and the news about the Taiwan Governor's Office can only be transmitted to Andong by crossing the Taiwan Strait by boat and taking 6 routes." ”

"What about the three governors of Nanyang?"

"The news of Nanyang can only be known after the beginning of spring next year." Xin'er said helplessly.

Except for the Kenting Peninsula in Tainan, which is in the tropics, the rest of the island has a subtropical climate, and even Xue Maoxun, who was stationed in Taipei, fell ill, and Li Yu was a little worried about the soldiers of the three governors in the tropical rainforest climate.

This strengthened Li Yu's determination to send Li Wenchang south to guard Puluozhong, and the generals transferred to him would also be transferred from Andong's armies to adapt to the climate of Nanyang according to Xin'er's proposal.

……

When Li Yu's appointment order came into Li Wenchang's hands, Li Wenchang looked at the appointment with a confused expression.

"What kind of place is Puluozhong? How far is Nanyang from Pyongyang? ”

Li Wenchang didn't know anything about Nanyang Puluo like an ignorant child, but His Royal Highness transferred him there, and the Jiaoduanwei led by him would also be reorganized, and people from Jiangnan and Lingnan would be transferred from the whole army to form a new Jiaoduanwei.

In addition, the dispatch not only sent him to lead the army to defend the Puluozhong in the unknown corner, but also carried out long-distance and close attacks on the small countries on the Malay Peninsula to gradually encroach on their territories, and strive to incorporate the land of the countries into the Tang Dynasty as soon as possible.

This is Li Yu's expectation of him, and then Li Wenchang's sad face.

In order to enable Li Wenchang to have an understanding of Pu Luozhong and the Malay Peninsula, where he would become famous in the future, he specially held a banquet in the Fuzhong, and invited him and General Colonel Kakuduan Wei to have a banquet and exchange with Zhang Qin, Yu Hong, Wang Haichong and others of the Nanyang expedition, and instructed him to take precautions.

At the banquet, Li Yu repeatedly instructed: "Whether you are defending Puluozhong or attacking the local Fanguo, remember that all the soldiers of the army should pay attention to food hygiene and not drink raw water." The station needs to fill the pond with quicklime for disinfection, and the river should not be silted up to avoid biting people and spreading the disease in the breeding place of mosquitoes. Biogas digesters need to be built to fill human and animal manure with fermentation before they can be used as fertilizer, and the reclaimed paddy fields can be stocked with rice, fish, or ducks to make mosquitoes......"

Li Wenchang and Jiaoduan Wei Changshi, Sima, Duwei and others took seriously everything Li Yu said, and they couldn't help but be serious, because Li Yu's first sentence was that these precautions were related to the life and death of Li Wenchang's troops and civilians, and it was not uncommon for them not to pay attention to the annihilation of the entire army tossed by the tropical epidemic.

Emperor Wen of Sui Chinese New Year's Eve an army of 10,000 troops to conquer Goguryeo from the 6th route, but because of a plague, he was killed and wounded before reaching the Liao River, and only a few thousand people returned in disgrace before engaging the Goguryeo army.

This is still in the north temperate zone, and in the tropics, you can imagine how severe the epidemic is.

Tropical malaria, which was feared and could not be effectively curbed in the era of advanced medicine in later generations.

The only way to effectively control the outbreak of tropical diseases is to modify the local ecological environment so that it is no longer suitable for the breeding of mosquitoes carrying the virus.

Before receiving cinchona trees from South America, the only thing in Li Yu's hands that could be used to treat malaria was Artemisia annua. (In later generations, due to the ignorance of Japanese scholars, the name of Artemisia annua, which has always been used as a medicinal use in country Z, was crowned on another non-medicinal plant, which became an international application, resulting in Tu Youyou and other scholars having to take the name of Artemisia annua to distinguish it, forming a situation where the same plant has different names in ancient and modern times.) ）

In the context of immigration to Taiwan, in the past two years, Li Yu ordered the Anton Pioneer Group to purchase a large number of Artemisia annua produced in various places while recruiting immigrants. Because Artemisia annua has medicinal properties only when it blooms in autumn, it is only purchased in autumn every year.

The amount of artemisinin contained in Artemisia annua produced in each place is different, and even some Artemisia annua has no medicinal properties, so Li Yu had to make the Artemisia annua collected by the Anton Pioneer Group must be clear about the place of origin, at least accurate to the township level.

In the past year, there have been several small-scale cases of malaria among immigrants to Taiwan, and after isolating the infected people, they were divided into dozens of batches to test Artemisia annua from different origins for efficacy verification, and finally eliminated some Artemisia annua from different origins.

According to the Eastern Jin Dynasty Ge Hong's book "Elbow Reserve Emergency Prescription" recorded in the book "Artemisia annua one hand, stained with two liters of water, wringed juice, and take it as much as possible" The method is now effective for the treatment of malaria, but the effect is very slow, and it must be taken for a long time to cure.

Li Yu estimated that this was because the juice contained in the juice from the water stained with Artemisia annua was not too much, and the artemisinin in Artemisia annua could be purified, which should be able to achieve the medicinal effect of later generations.

So far, the Andong Pioneer Group has purchased and hoarded Artemisia annua in large quantities in the autumn of this year, half of the stock has been shipped to Taiwan with the immigrant fleet that has left early, the other half is stored in the town of Tuli and Pyongyang for the needs of the fleet from these two places to the South Seas, and the rest is in the various migrant ports.

After the banquet was over, Li Wenchang and his subordinates were the chief of the guards, Sima and the three captains showed a bitter face.

No one is willing to give up a comfortable and comfortable life to suffer in the South Seas, which is tens of thousands of miles away, not to mention that it is still a wild land that needs them to reclaim and struggle.

During the banquet, no matter how Zhang Yao, Yu Hong and others covered it up, but through the precautions explained by His Royal Highness and the Nanyang expedition team, they knew that Nanyang was not a good land, and it was even more dangerous than the miasma, damp and hot Lingnan known to the people of the Tang Dynasty.
