Liu Wenjing and Yin Kaishan were carried by the rout, and fled all the way south for twenty or thirty miles before stopping. Liu Wenjing glanced at it, and there were only one or two hundred personal soldiers left beside him. He grabbed the reins with a "whoop," and turned his horse's head to look around, discerning the direction.

Yin Kaishan came over with a horse, and when he saw Liu Wenjing riding his horse and wanting to leave, he stepped forward and grabbed his reins, and said loudly: "Where are you going?" ”

"I'm going back. The prince is still in Gaojaw City, I want to save the prince! ”

"Are you crazy? Now go back, isn't that going to death? ”

"Then you can't let the prince fall into the hands of thieves, right?" Liu Wen shouted hoarsely.

Yin Kaishan slowed down his tone and said, "You calm down, we only have so many people left, even if we go back, we can't save the prince." Besides, the prince heard that we lost the battle, and he may have left Gaojaw City a long time ago......"

While the two were talking, a personal soldier next to him suddenly pointed with his hand and said, "My lord, look, the thieves are catching up!" Liu Wenjing and Yin Kaishan looked up, only to see flags waving in the distance, dust flying, and the sound of hurried horses' hooves faintly came. Apparently, the enemy's cavalry had caught up.

Yin Kaishan hurriedly urged: "Lord Liu, let's go, I won't be able to leave if it's too late!" Liu Wenjing hesitated for a while, but finally pulled back the horse's head and fled south with everyone.

Li Zhiyun and the others left Gaoqi City, first to the east, and then to the south, heading towards Chang'an. They encountered many routed soldiers along the way, and the banners, weapons, and armor of the Tang army were thrown everywhere. The faces of the people were heavy, and no one spoke. They had been walking for less than half an hour when they suddenly heard someone shouting, "Oh no, the thieves are catching up!" When the routs who were originally crowded on the official road heard this, they hurriedly left the avenue, and the rats ran around and fled in all directions.

Li Zhiyun turned his horse's head and looked behind, only to see that on the horizon in the distance, in addition to the hunting and flying military flags, there were countless small black dots moving forward rapidly. Apparently, it was the enemy's brigade cavalry. Zhang Zheng rode over and said, "Lord Wang, the enemy soldiers are catching up, what should we do?" ”

Li Zhiyun didn't answer, but looked back at the team he led. There were two or three hundred people in the team, in addition to his entourage and guards, there were also the second brother's personal soldiers, less than half of whom had horses, and several soldiers had to carry the second brother's stretcher. At the speed of their march, it would not be long before they were caught up by the enemy's cavalry.

The yellow horse under Li Zhiyun's crotch neighed and spun in place, as if complaining about why the master didn't slip away? Li Zhiyun looked up and found that there was a fork in the road not far ahead, leading to an unknown place. He resolutely pointed with his hand: "Leave the avenue, take that path, and dodge the enemy's cavalry first." ”

Zhang Zheng hugged his fists and said: "Obey!" Then he drove his horse to the front of the procession, and left the official road with the team, and stepped on the fork in the road, heading southwest.

The group walked on a narrow dirt road, through a large wooded area, and then entered the hilly and mountainous area. The trail becomes more and more rugged, sometimes uphill and sometimes downhill, with rolling hills on both sides. The mountains are lush with trees, verdant bamboo forests, and beautiful scenery and fresh air.

The team walked for more than two hours, and when the people were sleepy, a village appeared in front of them. Li Zhiyun saw that the sun had sunk in the west, so he asked the guards to tell Zhang Zheng that he would spend the night in this village tonight.

The village is not large, with about 100 families, and is located in a wide valley. The east side of the village is bordered by mountains, and the other three sides are fertile fields. There is a small river in the west of the village, and the willow trees on the riverside are clinging, and the scenery is pleasant. After entering the village, the group rented some houses from the villagers and settled down, and spent some money to buy some grain and vegetables.

Li Zhiyun didn't bother to take a breath, and came to the second brother's house. The second brother lay on the bed and fell asleep all the time. As soon as Li Zhiyun moved a bench and sat on the edge of the bed, Dr. Jia led a personal soldier into the room, holding a coarse porcelain bowl in his hand.

"The decoction is boiled, wake up the prince, it's time to take the medicine." Doctor Jia said.

Li Zhiyun hurriedly pushed the second brother with his hand and said, "Second brother, wake up, wake up, take medicine." The second brother opened his eyes and stared at him in a daze.

"Second brother, it's time to take medicine." Li Zhiyun stood up as he spoke, helped the second brother to sit up, and took a futon to cushion his back.

The soldiers wanted to feed the second brother medicine, but Li Zhiyun refused to let him. He took the porcelain bowl from his own soldier's hand, sat down and scooped a spoonful with a spoon, and handed it to the second brother's mouth. The second brother opened his mouth, swallowed the decoction, then turned his head, looked at the room, and said, "Fifth brother, what kind of place is this?" ”

"A farmer's house." Li Zhiyun said, scooped another spoonful and handed it to the second brother's mouth.

The second brother took the medicine and said, "Why are we here?" How's the situation at the front? Li Zhiyun didn't know how to answer, so he had to say, "Second brother, take the medicine first, and talk about other things later." The second brother suddenly reached out and grabbed his arm and said, "Fifth brother, tell me quickly, what happened to the front line?" Don't lie to me, tell me the truth! ”

Li Zhiyun was helpless, so he had no choice but to say: "Zhang Zheng is late, Liu Wenjing and Yin Kaishan fell for Xue Ju's trick and lost the battle. When the second brother heard this, he was stunned for a moment, and suddenly coughed violently.

When Li Zhiyun saw it, he hurriedly handed the medicine bowl to his own soldiers, stood up to help the second brother beat his back, and said, "Second brother, don't worry, your body is important." Victory or defeat is a common thing in soldiers, and when you get well, you will be able to defeat Xue Ju by leading your troops to fight against him! ”

The second brother leaned on the futon and gasped, and after a while, he muttered: "Fifth brother, what you said is good, when I am well, I will go to Xue Ju to settle the account!" When Li Zhiyun saw it, he reached out to ask for the medicine bowl, and said to the soldiers: "King Chu, let's come." Li Zhiyun agreed, and swapped places with him. The soldiers sat down next to the bed and began to feed the second brother medicine.

It was night, and Li Zhiyun slept soundly because the day of marching was too hard. He was having a sweet dream when he was suddenly awakened and heard someone calling for the door outside the house. Li Zhiyun got up from the bed, lit a small oil lamp, opened the door and looked, it turned out to be the second brother's personal soldier.

"King Chu, King Qin is sick again, go over and take a look." The pro-soldier said eagerly.

Li Zhiyun hurriedly got dressed and went to the second brother's house with his soldiers. He lives in the same courtyard as his second brother, he lives in the West House, and his second brother lives in the East House. Li Zhiyun walked in and took a look, there were several people in the room, in addition to the second brother's personal entourage, Doctor Jia was also there, and the second brother was sitting on the bed shivering. Li Zhiyun walked over and said with concern: "Second brother, how are you?" The second brother's lips trembled: "It's cold, it's too cold, it's like falling into an ice hole......"

Malaria, commonly known as "pendulum", is a disease transmitted to humans by the bite of a mosquito infected with Plasmodium, and malaria attacks include chills, fever, sweating and intermittent periods. If the remaining Plasmodium parasites in the blood are not eliminated, malaria can recur, which is called reflare-up.

Li Zhiyun turned around, frowned, and said, "Doctor Jia, why hasn't my second brother's illness recovered yet?" Doctor Jia sighed and said, "After we came out of Gaoqi City, we ran all the way, and we had no conditions to decoct the medicine. The prince couldn't take the medicine on time, so he naturally couldn't recover. ”

Li Zhiyun was right when he thought about it, but fortunately, they had already settled in the village. This village has an ancient well that is hundreds of years old, so it is called Gujing Village. Gujing Village is surrounded by mountains, although it is somewhat closed and dilapidated, but the scenery is beautiful, the air is fresh, and it is a good place to recuperate. Li Zhiyun decided to stay here for a few days and concentrate on treating the second brother, whose condition could not be delayed any longer.

However, after they lived in Gujing Village for a few days, the second brother's condition not only did not improve, but became more and more serious, and finally he fell into a coma.

Li Zhiyun was so anxious that he couldn't help but get angry at Dr. Jia and said, "What's the matter? Didn't you say that you could cure my second brother's illness? ”

Seeing that the second brother's illness was improving, as Langzhong, Dr. Jia was naturally very anxious. But he was a little helpless, and stammered: "The king... What the prince got may not be the ordinary vivax malaria and malaria malaria, but the evil... ...... falciparum malaria"

"I don't care about malaria!" Li Zhiyun shouted, "Why is my second brother still not getting better after taking the medicine you prescribed?" ”

Jia didn't know what was going on. Your Royal Highness, the prescriptions prescribed by Jia are all in accordance with the medical book. Doctor Jia said, took out a yellowed book from the medicine box, and said as he flipped through it, "The famous prescriptions for malaria recorded in the book, Changshan, Shu lacquer, verbena, and white tiger and guizhi soup, Jia has tried them one by one......

Li Zhiyun was furious, stepped forward and snatched the book in his hand and threw it to the ground, roaring: "You don't mention any medical books to me, if books can cure diseases, what else do you Langzhong do?" Dr. Jia didn't dare to fight back, so he squatted down awkwardly and picked up the medical book, patted the dust on it, and put it back in the medicine box.

At this time, Zhang Zheng on the side persuaded: "Lord Wang, you dissipate your anger and let Dr. Jia think of a way again." If you keep blaming him, won't he have any more ideas? ”

Li Zhiyun calmed down. He knew that it was useless to get angry at Dr. Jia. After all, Dr. Jia is a man in the army, and he may be very good at treating knife and arrow wounds, but treating infectious diseases such as malaria may not be his strong point. Although Li Zhiyun does not know much about malaria, he knows that there are two specific drugs for the treatment of malaria in later generations, one is quinine and the other is artemisinin.

Quinine is extracted by Westerners from a species of tree called cinchona that grows in South America. At the beginning of the 15th century, Indians in South America discovered that the bark of the cinchona tree cured malaria. They peeled off the bark and dried it to make a powder, stirred it with water, and poured it on the sick to treat malaria, which was very effective. Therefore, the Indians kept the "cinchona" secret and stipulated that anyone who leaked the secret of this medicine to a foreigner would be severely punished.
