After the end of Su Pohan's exile, Qin Fan began to carry out logistics construction, and he earlier hung the captured 10,000 second-order war horses to Fang City at the price of ten silver, earning nearly 1,000 gold. With this money, a large amount of grain and building materials will be purchased, and it is expected that the infrastructure will be completed in about five days.

Qin Fan was brushing the fifth-order cavalry head in the tent, when suddenly there was a commotion outside, he walked out to take a look, only to see a group of wild yellow sheep suddenly appear on the grass in the distance, numbering a thousand. Qi Yue had already rushed over with a few teams of archers.

"The meat of wild yellow sheep can be more elastic than that of captive sheep, and that wild smell can bring a different taste." The Mongolian chef standing nearby said happily.

Half an hour later, the team came back, each horse was hung with three or two yellow sheep, just at noon, the leader of the gang began to set up a pot to cook, some with mutton soup, some directly barbecued.

Soon, the smell of delicious meat came from the military camps around Subohan, and Qin Fan tasted the fresh and thick bone broth that was sent, and the taste was really a rare delicacy.

However, within a few hours in the afternoon, something happened that frightened Qin Fan.

"Oh no! Childe, there are a large number of sergeants in the archer barracks with diarrhea and vomiting! Qi Yue ran over in a panic, and her bangs were stained on her forehead full of fragrant sweat.

"What! How could this happen? Qin Fan was surprised, he suddenly remembered the yellow sheep at noon.

Before Qin Fan could think of anything, Yue Ziyun also hurriedly broke into the big tent and said hurriedly: "Son, there are hundreds of lancers who suddenly have diarrhea and cold sweat, the situation is very bad!" ”

"It seems that there is something wrong with those yellow sheep! Isolate all sick people immediately! At the same time, all departments will be checked, and all those with diarrhea, fever and sweating will be isolated! Star Dragon! Immediately send a dark wolf to inform Qi Nanshi to send someone to escort Zhao Lian overnight! ”

Qin Fan felt as if there was some conspiracy in this, but he couldn't say it, he asked worriedly, "How do you feel?" ”

"Everything will be fine in the end!"

"Me ...... too"

Qin Fan nodded, it seemed that some of the yellow sheep had a problem.

In the evening, the situation developed worse than Qin Fan imagined, originally there were only more than a thousand people quarantined at noon, but as time went on, the number of people who were quarantined became more and more, and by this moment there were already four or five thousand people.

And there have been people who have died of dehydration due to continuous diarrhea. There is an unpleasant smell from the tents in the quarantine area, and the situation continues to deteriorate.

"Childe, the dark wolf has already passed on the information continuously, it is estimated that Zhao Lian will be in a hurry overnight, and she will arrive in Subohan at noon tomorrow."

Qin Fan looked at the quarantine area in the distance with a sad face, those were all fifth-order troops, it was a pity to die.

"How's the perimeter guard?"

"I have deployed more than 2,000 dark wolves within a hundred miles in all directions of Subohan, and I will never give the Mobei Army a chance!"

Qin Fan was relieved after hearing this, fortunately, Xiao Xie's Golden Fire Cavalry was taken as a vanguard by Qin Fan and went to the vicinity of the Haote Department one hundred and fifty miles northwest to ambush, otherwise the loss would probably be great.

In order to prevent accidents, Qi Fan has already begun to use Su Pohan's population limit to brush the fifth-order village to send and train in the Suha Ye Banner, although there is some tossing, it can only be so.

Throughout the night, 20,000 archers and lancers were attacked, and the death toll increased to 2,000. Qin Fan had to let Qi Yue and Yue Ziyun leave Su Pohan alone first, so that they would not be infected as well.

"What the hell is this? The speed of transmission is so fast! ”

Xinglong frowned, and said slowly: "I'm afraid things are not so simple, as far as I know, Yellow Sheep has always been afraid of life, and has always stayed away from people and survived in the wilderness. It's so weird to see a flock of yellow sheep like this near the barracks......"

"You're saying someone is playing a trick on us?" Qin Fan suddenly reacted.

"It is very likely that the yellow sheep has been living in the wild for a long time, has strong immunity, and is a herbivore, and it is rare to carry poison, let alone large-scale poisoning. You must know that there are thousands of soldiers who have broken out of the epidemic at the same time, and one or two yellow sheep can't do it, it must be more than 100 heads. And a group of more than 1,000 yellow sheep, with poison accounted for 10%, this is probably hard to believe. Even if the poison did infect hundreds of sheep, then the yellow sheep should be covered with skin and bones, but I have clearly seen that each sheep is very fat. ”

Xinglong turned his head to look at Qin Fan, stretched out his index finger and said: "Based on these points, I judge that there should be a master in the Mobei Army who used the yellow sheep to drug us, causing a lot of loss of strength among our sergeants, and then forcing us to retreat, or simply eat us while our military strength is weak!" ”

Xinglong's words made Qin Fan's back cold, as the power of the system that Qin Fan came into contact with became higher and higher, encroaching on their interests more and more, the intelligence of the NPCs finally made Qin Fan feel a trace of fear.

By noon the next day, the death toll had risen to five thousand, among which many of the archers had been hung up, but the good news was that Zhao Lian, a sixth-order physician, had arrived.

"It's cholera!"

Zhao Lian said solemnly after checking the pulse of hundreds of sergeants in a row: "Yellow sheep generally does not carry the poison of cholera, it must be caused by poisoning, and Gongzi should immediately send someone to collect a few flavors of Chinese medicine such as Huoxiang and hay." In addition, I also need to send someone to go out with me to collect skullcap, and codonopsis and other medicines will first curb the spread of the epidemic! ”

Although Zhao Lian is a woman, she is calm and comfortable with such a serious epidemic, Qin Fan can't help but admire it a little.

Skullcap and Codonopsis are medicinal herbs abundant in the grassland, in addition to Bupleurum and Licorice. These medicinal materials can often be seen in the grassland wild, but Qin Fan has never cared about these materials before, and now it seems that every material in the game has its own reason for existence.

Qin Fan ordered Yue Ziyun and Qi Yue to lead a large army to go out to look for herbs, and in one afternoon, the harvest was very rich, and Zhao Lian personally asked the cooks to boil the medicine in a cauldron. During this period, thousands of people died of dehydration, and Qin Fan was anxious in his eyes.

The good news is that he found a large amount of Chinese medicine in Fang City, because there are not many players who use Chinese medicine now, the number of pending orders is very large, and the price is cheap, Qin Fan didn't spend much money to get enough of it.

"The potion made from skullcap codonopsis is distributed to the non-infected sergeants first, and the licorice juice is immediately given to all the sick sergeants! In addition, someone was sent to boil water, and all sergeants who were seriously dehydrated had to be replenished. ”

When the potion came out, Qin Fan hurriedly ordered people to distribute it, and it was not until the evening that the death toll began to gradually decrease, and it was not until there were no new people who were infected that he completely relaxed.

Of the 45,000 people in the whole army, only 39,000 remain, and more than half of these 39,000 fatigue has been under the warning line.

Qin Fan just wanted to eat something, Xinglong came to report at this time, the various units of the Mobei Army once again gathered 70,000 cavalry to kill Su Pohan, and Xiao Xie's 5,000 golden fire cavalry was looking for an opportunity to try to delay the offensive of the Mobei Army.

"Tell Xiao Xie that he must do his best to hold off the Mobei Army, at least until tomorrow morning!"

Qin Fan estimated that the fatigue of the army should be able to recover above the warning line tomorrow morning, after all, Zhao Lian had already said that this was an acute and malignant gastrointestinal infectious disease, and the recovery speed was very fast. Coupled with the fact that Zhao Lian already has a special elixir to boost her spirit and restore her energy, I believe that it will not be a problem to restore 80% of her combat effectiveness.

"Zhao Lian, do you have a poison similar to this cholera?" The more Qin Fan thought about it, the more unwilling he became, and after thinking about it, he also thought of releasing drugs, and Zhao Lian also happened to have expertise in drug production.
