The princess returns strongly, and the divorced regent is busy chasing his wife

After a good rest and a full stomach, it’s time to get down to business.

"Where are they?" Ouyang Miaoling asked.

"They were placed in a private room by Feng Xing. Do you want to go see them now?"

"Yes...I have found the cause of the disease."

"Are they a plague?" Nangong Mingxuan asked with a worried look on his face.

"No"

"Their symptoms do not match those of the plague."

"The plague starts with fever, chills, and general weakness, followed by continuous coughing and wheezing, with a piercing cough as if the lungs are coughing out. The head also has a splitting headache, as if countless steel needles are stirring in the brain, making it unbearable."

"Symptoms of the plague also include body aches, severe joint pains, and muscle aches, as if bitten by numerous poisonous insects. Patients' skin will develop rashes and patches, which will itch unbearably, and some people will even develop ulcers and pus."

"Although their symptoms are very similar to those of the plague, it is easy for inexperienced doctors to mistake them for the plague, but in fact they are not."

"After testing their blood, I concluded that they were poisoned."

"Poisoned" Nangong Mingxuan repeated the word in disbelief.

"If it's poisoning, why is it contagious?" Nangong Mingxuan asked the doubts in his mind again.

"This poison can be developed by others. As long as one person is infected with this poison, he will spread it through saliva, and then through air circulation, the virus will be transmitted to everyone. Let's try to see if the antidote I developed is effective?"

"If the antidote is effective, we can prepare a large amount and distribute it to each of them." Ouyang Miaoling said as she handed the antidote to Nangong Mingxuan and asked him to give it to Feng Xing to give to those people.

"Also, you have to arrange for people to go to the villages most affected by the epidemic and collect some drinking water for me. I want to do some research." Ouyang Miaoling instructed again.

"Do you suspect that they poisoned the water source?" Nangong Mingxuan asked doubtfully.

"It's possible. The spread of this virus is not that fast. The most likely scenario is that the water source was poisoned, causing large-scale poisoning. The spread would be even faster." Ouyang Miaoling explained her suspicions to Nangong Mingxuan.

"Your guess is not unreasonable. I will send people to fetch water, and then notify the local authorities to guard all the wells to prevent more people from being poisoned by the water." Nangong Mingxuan suddenly realized and made a decision immediately.

"Oh... As expected of the Regent, your reaction is quite quick," Ouyang Miaoling joked.

"It is because of the princess's training over the years that I have achieved what I have today. I have to thank the princess for her training." Nangong Mingxuan replied with a smile.

"Who disciplined you? Stop it. Go and give the antidote to those people and see if it works."

"Okay... I'll make the arrangements right away. You take a rest first."

"Um"

Nangong Mingxuan took the antidote and went out to do something. Because she was too full, she couldn't fall asleep if she lay on the bed and continued to sleep.

Ouyang Miaoling decided to go out for a walk to see if there were any new discoveries.

Just as she opened the door to go out, Feng Xing came in.

"Princess, the antidotes have been given to them. After taking them, they vomited a lot of black blood. The symptoms are similar to what you guessed. They are indeed poisoned." Feng Xing reported the reactions of those people after taking the antidote.

"Okay... the antidote should be effective. Let's recuperate here for a while and see what happens."

"Yes..." Feng Xing bowed respectfully towards Ouyang Miaoling, his eyes full of gratitude and admiration.

This salute was an expression of his heartfelt respect for the princess.

Ouyang Miaoling waved her hand: "Okay, no need to do this again in the future. You know, I hate these red tapes the most."

Feng Xing said quickly: "Etiquette cannot be abolished, the princess is worthy of the respect from her subordinates."

Ouyang Miaoling smiled helplessly: "Okay... okay, whatever you want."

Ouyang Miaoling was about to walk past Feng Xing and go out, but was stopped by Feng Xing again.

"Where are you going, Princess?" Feng Xing asked.

"I can't sleep, so I want to go out for a walk to help digest the food," Ouyang Miaoling replied.

"Princess, the prince is not here and it's already dark outside. We are unfamiliar with this place, so it's better to let your subordinates follow us. If anything happens, we can have someone to take care of us." Feng Xing suggested.

Ouyang Miaoling felt that what Feng Xing said made sense, so she said, "If you want to follow, just follow me."

Feng Xing took the order, and as soon as Ouyang Miaoling went out, Feng Xing followed behind.

The two walked together on the dark street. There was no one on the street, and cold wind blew from time to time, making it look particularly desolate.

Suddenly, the light in a room in the distance attracted their attention.

"Fengxing, where should we go to have a look?"

"it is good"

So Ouyang Miaoling brought Feng Xing to the house where the light was on.

"Is anyone there? Is there anyone in the house?" Feng Xing went into the house first to check the situation, followed closely by Ouyang Miaoling.

"Who is it..." A hoarse old woman's voice in the room responded to Feng Xing.

"Old man, we are just passing by and came to your house to get some water to drink." Feng Xing made up an excuse to prevaricate.

"Oh... I'm asking for water. Wait for me."

After saying that, the old woman turned around and seemed to go back to the house to get them some water.

Sure enough, as Feng Xing expected, the old woman walked towards them with a bowl in each hand and a staggering gait.

"Come in, sir, girl, please have some water."

Feng Xing reached out and took the bowl handed to him by the old man, but did not drink from it directly. Instead, he put it aside.

He took the opportunity to ask, "Old man, can I ask you something?"

He wanted to take this opportunity to learn more about the place.

"Of course...what do you want to ask?" The old woman patted her chest and assured that she would tell the truth as long as she knew it.

"Old lady, why are there no other families in this town?" Feng Xing asked curiously.

The old woman sighed and said slowly: "Young man and young lady, you are from other places, right? A serious plague broke out in our town some time ago. Many people died as a result, and only a small number of people are left at home waiting to die." The old woman explained the reason in detail.

"Who else is there in the old woman's family?" Feng Xing continued to ask.

"No more. My son and daughter-in-law, grandchildren, daughter and son-in-law are all dead. I am the only one left in the family."

"Then why are you okay?" Feng Xing asked puzzled.

"I don't know. Maybe it's a special punishment from God. He spared my life and made me live a life worse than death."

"Young masters, aren't you thirsty? Drink some water. I'll go get some water from the spring behind the house tomorrow."

When the old woman said this, her words caught Ouyang Miaoling's attention.
