Even though the city is under such strict control, this strange plague is still spreading quietly. The source of the plague is completely unknown, and people can only be forced to watch as people in the city are infected little by little.

The atmosphere in the study was depressing.

Gu Chen looked at the number of people reported, his voice low and hoarse, his eyes bloodshot: "Major General, more than ten people were infected yesterday."

"I wonder when the miracle doctor you mentioned will arrive. We need help with the war outside the city, and there's a plague inside. I'm afraid..."

He didn't say the rest, but everyone understood what he meant.

If they continue like this, they might not be able to hold on any longer. They are currently helpless and can only pin their hopes on the miracle doctor.

Jiang Ling hummed, and said calmly: "This general has already sent a letter, and it will probably reach Pingcheng within seven days."

When Gu Chen heard that it would take seven days, his heart sank. According to the current rate of infection, how many people would be needed in seven days? Besides, even if the people arrived, it was still unknown whether they could be cured.

But these things cannot be said. If they are said, it will shake the morale of the army and the battle will no longer be fought.

There's a knock on the door.

The door opened and the guard came in, handing over a letter.

Jiang Ling opened her eyes and widened them a little. After making sure that she was not mistaken, her breath was held. San'er's method was really... risky. If it was not controlled well, this strange disease would spread.

Seeing his strange expression, Gu Chen asked in confusion, "What happened to the young general?"

"Close the door. This general has something to tell everyone."

"Based on the current clues, the source of this plague outbreak is most likely related to the people behind the Xiongnu. If we continue to tie up the sick people in the city like this."

"It can control the number of people who are sick, but it can't solve the fundamental problem. Since the Xiongnu are not afraid of fighting us, I think they know how to solve this plague."

"If we continue to wait for a miracle doctor, it will be too slow. Even if he comes, there is no guarantee that he can be cured. Now there is a simpler but riskier method."

Jiang Ling met their gaze and said in a deep voice, "Release those who are sick to infect the Xiongnu, and then have the spies find out if there is any solution to this plague."

"This way we can curb the passiveness of the war and find a solution to the plague more quickly. We just need to keep an eye on the infected Xiongnu people."

"But it's very risky. If both sides fail to control it, this strange disease will spread rapidly, and I'm afraid several countries will be in trouble."

Everyone was silent, not knowing what to say.

On the one hand, they felt that this method was too risky, but on the other hand, they felt that this method could solve the current dilemma. Otherwise, they would have to control everything inside and outside the city.

It is really impossible to split the city into two parts. If we leave the city, there will inevitably be casualties. If we don't leave the city, the disease will still be transmitted inside the city. We are in a dilemma and might as well drag the Huns into the water.

Gu Chen pondered for a moment, then looked at them and said in a deep voice, "Although the Young General's method is a bit cruel, for our current situation, there is no better way."

"Even if you want to release the infected, it's best to evacuate the surrounding residents beforehand, and release them at night."

"Otherwise, if it spreads, Dagan will inevitably be accused of maliciously spreading the plague. Other countries will be dissatisfied, and if they all attack us... it will be even more troublesome!"

"Oh, this plan of the other party is really vicious."

Jiang Ling took out the map and spread it out, noting on it: "Actually, there's no need to worry too much about this problem. There's a big river blocking the border to the east, and there are cliffs in the north that are insurmountable."

"To the west is the Xiongnu, and to the south is Pingcheng. Even if it spreads, it will not affect other countries, but will only have a big impact on the Xiongnu and Dagan. If we can't hold the Pingcheng line of defense."

"Then we will be the culprits for the fall of the Northern Wasteland. If we don't fight, we will all perish."

Everyone looked at the map and nodded, "Young General, what you said makes sense. Although this is a bit risky, as long as we can force the Xiongnu to find the antidote."

"All problems will naturally be solved. If we don't do this, the spread rate can be curbed a little, but it will be useless if we can't solve the source."

Half an hour later the door opened.

Gu Chen came out with a worried look on his face and whispered, "Young General, you've been traveling a long way. You'd better go to the backyard and rest. Those infected in the city will be arrested sooner or later."

Jiang Ling nodded: "Okay, General Ben will order the evacuation of the civilians. They must be properly arranged."

"We'll let them come back after the plague is resolved. The money they need to support us will be provided by the Marquis' Mansion to ensure that the people don't riot."

"Don't worry, General. I understand."

Jiang Ling followed the servant to the backyard, washed up and lay on the bed, but he couldn't fall asleep because he was worried about something.

A slight squeaking sound was heard, getting closer little by little.

Hearing the sound, Jiang Ling opened his eyes quickly, got out of bed, and walked towards the direction of the squeaking sound with the long sword in his hand. The sound became louder as he got closer.

I walked around the screen and looked at the mouse in the corner. I was a little surprised. It was still broad daylight, so how could the mouse be so bold?

Jiang Ling clenched the sword in his hand and was about to stab when the rat that was gnawing on the meat seemed to notice something and turned its head suddenly, its blood-red eyes looking ferocious and terrifying.

The mouse squeaked twice and pounced towards him to bite him. This strange scene happened, and there was no time to think about it. A silver light flashed and the mouse's head and body were separated.

It fell to the ground with a plop, and a foul smell wafted over, making me nauseous. I squatted down and took a closer look.

In the black blood, a wriggling red thread flashed by and quickly disappeared into the mouse's body.

Jiang Ling narrowed her eyes and stared, trying hard to recall what she had just seen. What on earth was that red thread? Why did that...worm-like thing appear in the mouse's body?

The mouse appeared in front of people in broad daylight and attacked them. Could it be related to these red silk threads?

The door was flung open, and the guard rushed over and asked worriedly, "Sir, are you okay?"

"Hmm? Why is there a rat here? I'll take it away right away."

As he reached out to take it, Jiang Ling stopped him: "Wait, don't move. There's something wrong with this rat corpse. There are red threads in its body. Perhaps these red threads are the source of the plague."

Konoe was stunned, obviously not expecting this to happen.

"Go call General Gu over, and hurry up."

"Yes, Major General."

Not long after, Gu Chen came hurriedly and asked after entering the room: "Young General, is there anything wrong that you need to see me?"

Jiang Ling stood up and put his sword into the charcoal. He had just killed the rat with the sword, so who knew if it was stained with red thread.

"General Gu, look at this dead rat. I heard some noise and came over to see it. It was gnawing on a piece of meat. Its eyes were blood red, just like the people in the dungeon."

Gu Chen looked at the dead rat on the ground, his pupils suddenly shrank, and he obviously thought of something, his body trembling slightly.
