The towering Qinling Mountains.

Separate north and south.

The humid and humid weather in Bashu gave birth to the splendid civilization of Bashu, but it also made the Guanzhong children who were accustomed to the cool and strong winds very uncomfortable.

The illness comes like a mountain falling.

The continuous battles and long journeys have very high requirements for people's physical and mental health. Before Shu County was captured, the Qin army was inspired by a target, and each soldier's heart was burning like a ball of fire, which made them ignore physical fatigue and discomfort.

When victory and triumphant return, the Qin generals who had relaxed their minds suddenly lost their vigilance. The fatigue and illness of their bodies came one after another, causing these fearless soldiers on the battlefield to fall down.

In fact, as early as May when they entered Ba County, there were generals in the Qin army who fell ill. At the beginning, there were only one or two soldiers in each battalion in good health. The medical officer thought it was an ordinary minor illness and did not take it seriously. He simply cooked some herbs to deal with it. As for the effect, it cannot be said that it was useless. A few strong men survived.

The medical officers in the Qin army could only simply treat some ordinary trauma, and there was almost no way to deal with this sudden large-scale plague.

One after another.

Team after team.

It persisted until the end of June and early July, when the Qin army returned from the south and north, the sick soldiers in the army suddenly increased overnight. By the time Li Yuan fell in early July, Li Zhongxiang and several generals had been carried by the soldiers for a few days.

"Shenhou, this is the miasma from the south, and it is beyond help. It is better to leave the soldiers who are seriously ill and unable to march first, and the army will start first. Otherwise, the entire army will be completely infected." The medical officer was helpless because he knew some alchemy prescriptions. Peng Sheng, who was temporarily appointed by Li Yuan to be responsible for medical affairs, ran to Li Yuan to report.

"Muscosis, can you be sure?" Li Yuan looked solemn and stared at Peng Sheng. On the hot July day, Li Yuan was wearing several layers of thick armor. He was also tortured by malaria, and his body was hot and cold, which made him, who had always been strong, unable to withstand it.

If Li Yuan had no modern mind, he might have made such a ruthless choice.

Now, after receiving the modern military education of "not abandoning, never giving up", he will never make a decision to abandon his soldiers no matter what. As long as there is still a glimmer of hope, he will do his best. This is the creed that Li Yuan adheres to and the motivation for his deep love among the generals of the Qin army.

"The Lord Shen. It's true. Although his subordinates failed to achieve medical skills, they also followed their teachers to see the power of miasma. If they were treated late, I'm afraid that the Lord Shen was also--!" Peng Sheng looked depressed. He was anxious just now, and forgot that Li Yuan was also a member of the sick stroke. It was really unwise to suggest that the sick soldiers would die by themselves.

"You just try your best to treat the seriously ill soldiers, and don't need to worry too much about anything else. As for the invasion of miasma, you must not tell others. If I let this marquis hear it, be careful of your life." Li Yuan's face darkened and he shouted. Peng Sheng is a new supporter, and his loyalty remains to be considered. When no one is available, Li Yuan can only use it while knocking. If Peng Sheng knew the image, he should be able to hear Li Yuan's warning.

"I understand, please don't worry, Lord God." Peng Sheng said with a stern expression and responded with surprise and joy.

Peng Sheng was shocked that Li Yuan had not adopted his suggestion, which made Peng Sheng feel extremely stressed. As more and more soldiers were sick, the speed of the Qin army's marching would be greatly reduced. In this case, it was almost impossible to get out of Chen Cang Road.

What was so happy was that Li Yuan had the intention of using him. He finally surrendered to Qin and was appreciated by the young Shenwu Hou. He was able to follow him to Guanzhong. This was the first of all officials in Shu County. Peng Sheng didn't want to give up just like that.

"Wait a minute, you will send me the order quickly: the entire army immediately checks soldiers who are afraid of cold, headaches, and fever, and move to camp and stop. The cold water that has not been boiled shall not be consumed. The clothes, weapons and other items that the soldiers contact every day must be soaked in boiling water before they can be used. Those who violate this order shall be killed!" Li Yuan thought for a while, and called Peng Sheng and ordered.

Miasma poison was a type of falciparum malaria in later generations. Isolation was the most important thing in terms of treatment. After confirming that it was miasma poison, Li Yuan searched for the dry intestines and finally remembered three preliminary response measures.

"I'll do it now." Peng Sheng looked happy and responded anxiously. The precautions proposed by Li Yuan gave Peng Sheng a glimmer of hope to walk out of the jungle again.

The attack of falciparum was much more powerful than Li Yuan imagined. The great plague that spread across the Qin Expeditionary Force showed its power and terror from the very beginning.

Peng Sheng's reminder made Li Yuan realize that this was not an ordinary disease at all, but a plague. If the spread of malaria cannot be prevented, the invincible Qin army on the battlefield is very likely to disappear into the Qinling Mountains due to malaria.

The damp and hot weather is the cause of toxic miasma. This falciparum spread by mosquitoes is extremely terrible. Not to mention that it was in the Qin Dynasty, but it was a disease that made people feel disgusted when they were heard.

From Jushui to the old way.

The Qin army was advancing step by step with difficulty. After being quarantined, the Qin army's march speed slowed down again and again. When the army finally reached the northern foot of the Qinling Mountains, it finally stopped.

Five thousand generals and soldiers were infected with one-third of the plague. From the beginning of the Battle of Hulao Pass, Li Yuan led the Qin army to fight east and west, from the Didao grassland in the north to the Bashan and Shushui in the south, they defeated one enemy after another who threatened the Qin Dynasty, but were unable to defeat the enemy who threatened their bodies.

Wuzhangyuan.

This place was famous for being killed in the Three Kingdoms during the Three Kingdoms because Zhuge Liang, the prime minister of Shu, died of illness. It was named Pituopo in the Qin Dynasty. Later, it was named after Hu Hai's sentence "Autumn Wind Wuzhangyuan".

The army reached Wuzhangyuan and could hardly move half a step. Along the way, there were six or seven hundred Qin soldiers who died of illness. Among them, some of them had poor constitutions and died in just a few days.

Li Yuan has been infected for five days. Compared to being able to answer Peng Sheng a few days ago, he is now almost unconscious. This news has left the Qin army in a breath of death.

In this era when ignorance just began, Li Yuan's battlefield deeds made the soldiers in the army think that their Shenwu Hou could do everything and nothing could knock him down. Now, the disease is coming, and even Shenwu Hou has no choice.

July 15th.

The eldest princess Ying Yushu and the eldest son Chen Ping finally arrived at Wuzhangyuan. What they saw was the festive scene of the Qin army returning from the triumphant expedition, but the scene of sad clouds and mist.

When the medical officers who came with him saw this, they all took a breath. Such a large-scale plague attack was a great test for their medical skills. If they could not show their skills this time, they would probably have finished their meal.

"Mr. Gongsun, Mr. Li has fainted for five days. What is the situation?" Ying Yushu said sobbingly. She was originally thinking that she was stopped by Gongsun Guang, a senior doctor who was accompanying him. She could only take a look from a distance, but could not see what Li Yuan looked like.

"Princess, please feel at ease. Mr. Li's condition is indeed dangerous, but there is still hope for treatment--" Gongsun Guang said word by word.

"Then I'll have a hard time. When I save Mr. Li, I will definitely give me a lot of rewards and write books for me, so that my skills can be passed down for thousands of years." Ying Yushu said.

"The eldest princess is intent." Gongsun Guang said in a state of emotion.

Qi was in turmoil, and there was no place for doctors to study medical skills. Gongsun Guang went to Qin this time to seek a country that could provide him with his medical skills to join him. On the other hand, he also wanted to compete with another big guy in Qi, Gong Baiyangqing, to see who has the better medical skills.

Ying Yu rinsed the proposal of medical books to inherit his medical skills to the point of Gongsun Guang's thoughts. People always have seven emotions and six desires. For a doctor, treating patients is the most important, while writing books to inherit medical skills is the most touching of their hearts. Gongsun Guang did not seek to kneel down for millions of people like Huangdi, but he also hoped to pass on medical skills and medical ethics to future generations like the genius doctor Bian Que, so that his name would be praised by doctors.

A great doctor like Gongsun Guang is undoubtedly much better at studying Chinese herbal medicine than Li Yuan and Peng Sheng who came from halfway through. Under his command, a team of Qin soldiers, under the leadership of their respective medical officers, cleaned the place of the sick soldiers while using herbal medicines such as realgar and Atractylodes to take them.

Under Gongsun Guang's careful treatment, Li Yuan, who had been in good health, finally saved his life from the gate of hell after seven days of unconsciousness. However, his body was still very weak and it took some time to recover.

As for other patients, most of the patients had improved. The soldiers who unfortunately died of the epidemic were instructed by Gongsun Guang that the bodies, clothes, etc. were burned into fire and buried deep into remote places.

After rescuing Li Yuanzhong's army, Gongsun Guang did not stop and headed south to the generals such as Wang Shang and Feng Xuan who were stationed in Hanzhong, Ba and Shu County to check whether the plague had spread among their army.

It's early August.

Finally, Li Yuan, who was basically cured, decided to return to Xianyang and the soldiers who returned with him were reduced from more than 5,000 to only more than 2,000.

The power of the plague caused huge losses to the elite Qin army. Li Yuan was the first time since he joined the army to turn back to Xianyang in a carriage. This extremely difficult summer in the third year of Qin Xinli, the Southern Expedition, which almost lost his life, ended.

After occupying Hanzhong, connecting Bashu, and connecting the Qinling Mountains north and south, after paying a huge price, the Qin State finally had a geographical advantage in fighting against the princes of Kanto.

Just as Li Yuan unified the Western Front and occupied Nanjun, the Han King Liu Bang, who was eager to get rid of the dilemma of being constantly pursued by the Qin army, also launched a war in the south. This time, the former Zhuguo of King Xiong Xin of Chu, and the Linjiang King Gongao became the target of Liu Bang's attack.

PS: I finally came back. This week I was really miserable. There was no network or electricity. I have been waiting for a long time. I won’t say anything else and will resume updates.
