Early in the morning, while Gu Lili was still asleep, she heard Gu Erniu's panicked voice.

Gu Lili jumped up immediately, hurriedly put on her coat and shoes, and ran to the shack next door.

At this moment, Gu Sigou was delirious with fever and hadn't even opened his eyes.

Gu Lili hurriedly climbed onto the bed and touched Gu Sigou's forehead with her hand. At this moment, Gu Sigou's forehead was burning hot.

She clearly had a high fever, so Gu Lili quickly got off the bed and went to the corner of the kitchen to buy ibuprofen.

When Gu Lili looked up, she saw that Gu Ergou's face was abnormally red, so she quickly raised her hand to check his temperature.

Unexpectedly, Gu Erniu thought Gu Lili was going to hit him, and he was so frightened that he instinctively covered his head and squatted down.

"Erniu, what are you doing? I just wanted to test if you had a fever!" Gu Lili said irritably.

Upon hearing Gu Lili's words, Gu Erniu stood up somewhat awkwardly and leaned his head towards Gu Lili.

Gu Lili almost laughed. Had she been too harsh on Gu Erniu? It seemed she would have to be gentler in the future.

She smiled and reached out her hand; sure enough, it was terribly hot.

"Erniu, you have a fever too. You and Sigou should lie down and rest for a while. I'll go get some medicine for you." Gu Lili's smile faded, and she said with a serious expression.

Gu Erniu nodded, obediently took off his shoes, and lay down on the bed to sleep.

Gu Lili's words made him feel dizzy and lightheaded.

Gu Lili was puzzled. Logically speaking, it wasn't cold last night, so why did both children have fevers?

Since Gu Erniu is awake today, we can't buy ibuprofen suspension.

Gu Lili clicked to take a look, and thankfully, there were still powdered medicines available for purchase.

After buying the medicine, Gu Lili quickly boiled water to prepare medicine for her two younger brothers.

After preparing the medicine and serving it to the two of them, Gu Lili seemed to remember something.

Why didn't Gu Huanhuan get up today? Usually, if I get up by myself, Gu Huanhuan will get up soon after.

Gu Lili thought to herself that something was wrong and quickly walked towards the shack next to her.

As soon as I entered, I saw that Gu Huanhuan's face was also flushed. Without a doubt, she also had a fever.

Gu Lili touched Gu Huanhuan's forehead, and sure enough, that was the case.

Just like Gu Sigou, Gu Huanhuan was now delirious with fever.

Gu Lili couldn't help but blame herself. Last night, she felt that the bed was very warm and thought it was because of the blanket.

If he had discovered it sooner, Gu Huanhuan would have suffered less.

She hurriedly went to the kitchen and brewed another bowl of medicine for Gu Huanhuan to drink.

After the three children took their medicine, Gu Lili went to make breakfast.

Since you have a fever, you should eat something light.

Gu Lili cooked a rice porridge and stir-fried some bracken.

Once everything was ready, Gu Lili went to wake the three of them up for breakfast. They had been taking their medicine for half an hour, and their fevers should have subsided by now.

"Erniu, Huanhuan, Sigou, dinner's ready!" Gu Lili called out as she walked towards the shack.

To her surprise, no one paid any attention to her, so Gu Lili quickly hurried towards the shack.

She went to Gu Huanhuan's bedside first and reached out her hand, but to her surprise, the high fever still hadn't subsided.

Gu Lili went to the shack next door to check on Gu Erniu and Gu Sigou.

They were in the same situation, and now Gu Lili was completely panicked.

She doesn't understand medicine either, what should we do now?

Moreover, Gu Lili felt her throat starting to feel uncomfortable and was very painful.

Gu Lili guessed that they probably had the flu, but she wasn't sure, since she didn't have a fever herself.

After thinking for a moment, Gu Lili decided to go to Yang Dadan's place on the estate to have him take a look.

When I arrived at Yang Dadan's house, I was surprised to find so many people gathered there.

Coughing, Yang Dadan shooed people away, saying, "I'm out of medicine. Go look somewhere else and don't bother me! I feel terrible too!"

"Oh, you're so bold! Our whole family has a fever. How can we go anywhere else to get checked out? Can't you just tell us what medicine we should take? We can even go up the mountain and dig some ourselves," said Tie Dan's mother from the side.

Yang Dadan said impatiently, "You wish! If I give you the prescription, you can become a doctor too! Get out of here! Besides, this is probably a plague. What if it infects me?"

Starting yesterday evening, villagers began to come to see the doctor one after another, and at first Yang Dadan was quite happy.

Although he likes to swear, anyone would be happy if someone delivered money to their door.

However, as more and more people gathered, he gradually realized that something was wrong.

There's no reason why so many people would get sick all at once; they've probably all contracted a plague.

Right now, we don't have much medicine left at home. If it really is an epidemic, we'll have to keep it for ourselves.

When Tie Dan's mother heard Yang Dadan say that, she was furious. She had a fiery temper and was only trying to reason with Yang Dadan for the sake of her child and husband. She was even more angry that Yang Dadan cursed her.

"You're talking nonsense! You're the one who's got the plague! You think I won't slap you to death?!"

As she cursed, Tie Dan's mother took off her straw sandals, ready to slap Yang Dadan in the mouth.

Startled, Yang Dadan slammed the door shut.

"Iron Egg's mother, you've been infected with the plague!" After closing the door, Yang Dadan started cursing again.

Enraged, Tie Dan's mother was about to bang on the door when Gu Lili and the other patients quickly stopped her.

"Auntie, don't take it to heart. Since he won't look, why don't you go look at other places?" Gu Lili said.

When Tie Dan's mother saw Gu Lili trying to persuade her, she coughed a few times and said, "There are no doctors around here. If we want to go, we can only go to Donghai Town. Sigh, could what Yang Dadan said be true? Is it really the plague?"

Hearing Yang Dadan say this confirmed everyone's suspicions.

If it wasn't a plague, then why did so many people suddenly get sick?

Everyone sighed and said, "Let's make some plans as soon as possible. If we can walk to the town, let's go and take a look."

After returning from Yang Dadan's house, Gu Lili's expression turned serious.

The "plague" that Yang Dadan mentioned should be a type of infectious influenza.

It's possible that the outbreak was caused by the freezing rain that fell a few days ago.

In modern times, influenza and pneumonia can at least be treated with antibiotics. In ancient times, although traditional Chinese medicine was effective, it was too slow to take effect.

Sometimes, the fever might not have subsided before the body can't take it anymore.

Therefore, people in ancient times would avoid influenza at all costs.
