It was autumn, and the leaves of the palace were rustling down.

As Yuwen Di spoke, he couldn't help but let out a heavy sigh. In the past few days, I have been having nightmares about the Little Thirteen falling from his horse and becoming a serious injury. "Therefore, I am truly worried in this heart."

"Your Majesty is overthinking. Thirteenth Princess is the commander of the army, she is in charge of the overall situation so how could she fall from her horse? " "The Eunuch Ming consoled the emperor nonstop. With so many people in the army protecting the princess, nothing would have happened to her. Perhaps in a few days, the princess will return in triumph. "

Eunuch Ming kept on saying words of consolation to the emperor, and the emperor's heart finally settled down a little.

As the Emperor brought the teacup to his face, he said to the Eunuch Ming, "I'll wait for three more days. If there's still no news of the front lines within these three days, send someone to quickly check them out. We must let him know of the situation on the battlefield."

The Eunuch Ming accepted the order and slowly retreated.

Early that morning, Xiu Heng woke up feeling all sorts of discomfort, and immediately collapsed on the bedside.

Seeing that, Duan Yunfei was shocked, and anxiously ran out.

"Thirteen, come back." Xiu Heng called out to Duan Yunfei with much difficulty, frowned and asked her: "What are you going to do?"

"Since you've suddenly become so sick, I naturally have to go to the general's doctor to have him treat you." Duan Yunfei was in a hurry, he anxiously spoke to Xiu Heng, and turned to leave.

"Absolutely not." Xiu Heng used all his strength to stop Duan Yunfei, and anxiously said to her: "Thirteen, if you go out like this, others will definitely notice you, and it would be safer to order the soldiers who are guarding the camp to pass on a message."

Hearing Xiu Heng's words, Duan Yunfei hesitated for a moment, then nodded at Xiu Heng.

When the army's marching doctor arrived at the camp, Xiu Heng's face was pale white, his lips were black and green, scaring Duan Yunfei speechless.

The doctor took a look, sighed, and then turned to Duan Yunfei and said: "Reporting to Sir, Crown Prince Xiu Heng is suffering from an infection."

"Infected by plague?" Duan Yunfei was startled, she anxiously asked the doctor: "Doctor, are you sure you made a mistake? How can you be infected with the plague?"

The marching doctor shook his head, then turned to Duan Yunfei and said: "Your Excellency doesn't know, one day ago, for some reason, the army was infected with the plague, and many soldiers were infected by it. Khan ordered the military doctors to do their best to develop the antidote. "

The doctor looked at Duan Yunfei, and paused for a moment before saying: "However, this is a secret of the army, if the enemy were to find out, the consequences would be unimaginable, and must not be revealed."

Duan Yunfei nodded, and couldn't help but start pondering in her heart. Golden Horde Kingdom's soldiers suddenly had a plague, which was so strange. It was hard not to be suspicious.

"The plague got infected extremely quickly, so Prince Xiu Heng must have touched something that was contaminated with the plague, which was why he got infected." The doctor told Duan Yunfei as he felt Xiu Heng's pulse.

Duan Yunfei nodded lightly. This plague is approaching menacingly, what should my crown prince do now? " Duan Yunfei glanced at the doctor, and acted as though he was a bodyguard, and asked with an overbearing tone.

"This …" The doctor hesitated for a moment, then bowed to Duan Yunfei. Now that the military is in a critical situation, the doctors in our army are giving their all to develop the antidote. Before this, I can only prescribe a few pills for Crown Prince Xiu Heng to save his life. "

"How long can these effects last?" Duan Yunfei expressionlessly looked at the doctor and asked.

"Seven days." The doctor hesitated for a moment, then sighed and said to Duan Yunfei.

Hearing that, Duan Yunfei raised her head and looked at the doctor. In other words, if you guys are still unable to develop the antidote in seven days, my Crown Prince will die here? "

Duan Yunfei's eyes were filled with sharp blades, scaring the marching doctor in front of him, causing him to immediately kneel on the ground. She couldn't say a word.

Duan Yunfei did not care about all this, she looked down at him and said: "I can only give you five days. If you guys are unable to develop the antidote within these five days, I must bring our crown prince back to the Xiliang to treat his illness."

"Little General, Xiliang and Golden Horde Kingdom are currently in a period of negotiation, you must not let these small matters harm the relationship between both sides." When marching doctor saw Duan Yunfei's angry look, she felt that something was wrong and quickly advised her.

"A small matter?" marching doctor's words immediately angered Duan Yunfei. Now that my family's crown prince is on the verge of death and is lying unconscious here, you actually dare call this a small matter? "

"My words were wrong, please don't take it to heart, young general." marching doctor heavily knocked his head on the ground, and kept talking to Duan Yunfei.

Duan Yunfei did not want to waste anymore time with him, so she waved his hand, signaling him to go out. Since my words have come to this, you should know what to do. If the doctors in the Golden Horde Kingdom Army are incapable, I can only bring my crown prince back to Xiliang for treatment. "

Duan Yunfei hesitated for a moment, and stared fiercely at the doctor in front of him. However, if you delay the diagnosis of my family's crown prince, the entire Xiliang might not let you off. "

Now that the Golden Horde Kingdom and the Xiliang had just reached an alliance, the Jin Country's army was already heading towards the north like tigers eyeing their prey. If there was any disagreement between the two, it would definitely affect the alliance of interests between the two countries that had just been formed. When everyone disintegrates, the Golden Horde Kingdom will definitely be defeated by the Jin Country.

"Yes." marching doctor replied with a shaky voice. Even his forehead was covered in cold sweat.

Seeing the current state of the marching doctor, Duan Yunfei didn't want to say anything more and waved him away, gesturing for him to leave.

"General, Crown Prince Xiu Heng is infected with a plague, it is extremely contagious, so it is better for General Xiu Heng to be careful." marching doctor was about to leave, but he turned around and warned Duan Yunfei about the doctors and their parents.

"Thank you, Doctor." Duan Yunfei cupped his hands towards him and ordered him to be escorted out of the camp.

At this time, only Duan Yunfei and Xiu Heng was left in the tent.

Xiu Heng was unconscious, and his entire being looked extremely uncomfortable. His complexion was pale and did not resemble that of a common plague.

Of course, if it was just an ordinary plague, the army wouldn't be so flustered.

Duan Yunfei crouched down and carefully examined Xiu Heng's symptoms, and in the end, couldn't help but raise the corner of his mouth.

"It really is you." Duan Yunfei saw through the symptoms and sat on the side of the bed, and couldn't help but curse in her heart.
