slumped onto the bed."Hey, don't play dead..."Dugu Cheng pulled her arm, his eyes catching sight of the blood on the sheets. He hurried forward to check and saw the bloodstain on the back of her head...."No matter how many herbs it takes, I will cure them."

Feng Lingxi looked at Lord Liu, saw that he did not speak, and got into the carriage.

Back at the inn, Feng Lingxi first went to freshen up before going to eat. After the meal, it was already past midnight.

"Sister, I bought the cinnabar you asked me to buy, but I don't know if it's enough."

Feng Yu Mo knocked on the door and came in, carrying a bag of realgar in his hand.

Feng Lingxi stepped forward to take a look, nodding.

"Use only as much as you have now."

Feng Yu Mo looked at his elder sister's slightly furrowed brow, "Sister, what role does this realgar play in treating this illness"

"Detoxify, anti-inflammatory and swelling reduction, most importantly kill parasites."

"Go pest-control"

Feng Yu Mo wore a puzzled expression, "Sister, you mean all of them fell ill because they were poisoned by insects"

Feng Lingxi thought, "If you say it was insect poison, it would work. They should have been infected by drinking contaminated water, and this source of water should have been deliberately tampered with."

"Sister, do you mean that only people who drink water will... and those who don't drink water won't"

"At present, it appears to be so, with no infection."

Feng Lingxi took up her pen and ink, starting to record what she had discovered today. The woman holding the child began with no signs of infection on her body. The other infected patients were also individually ill, with no cross-infection.

"That's not a plague, is it"

"No, not now. If it were a while longer, it might be different."

This kind of infection, the thing to fear is complications.

"My lady, the lord has arrived."

Little Li happily knocked on the door. Feng Lingxi glanced at the time outside, "She's been so long, did she encounter anything on the way"

"No, I just went to check the situation in Eastern Thailand and just entered the city."

Little Li's voice had just fallen, when Dugu City walked in. Seeing Feng Lingxi hadn't rested yet, he stepped forward and asked, "Xi'er, this king heard that you went to see the patients today, how are they doing"

"Someone must have poisoned the water they were drinking. The source of this poison is pretty disgusting, it's probably an infection…"

Feng Lingxi looked at Dugu City, “Forget it, I won’t say it, lest it disgust you.”

Upon hearing Xi'er's words, Dugu City had already guessed the gist of it.

"Is there any antidote"

I've already started on the medication, but the priority right now is finding the source of the water. Otherwise, people will continue to get sick if they drink from it.

Dugu City nodded, "Tomorrow have someone investigate where they drank the water and start checking the water sources."

"That's all we can do for now."

This water source is a major problem. Only by finding it can we completely eradicate the spread of this disease.

"Did you find anything during your patrol"

Feng Lingxi watched the wind blow through Dugu City. The dust-covered face probably hadn't run much.

The Dongtai army had withdrawn to a hundred miles outside the city and encamped there.

Then what are your plans

Dugu Cheng looked at Feng Lingxi, “First, find out the source of the infection. Then, treat the people and soldiers. After that, we can discuss the matter of Dongtai Kingdom.” They had no intention of attacking Tumuwzhen for now, they could only defend first. After all, in a war between two armies, if the surrounding water sources were problematic, it would easily lead to trouble. It was too risky to take chances.

"Alright, I will continue to research the antidote tomorrow."

Feng Lingxi pondered for a moment, "Where did Dugu City and Sun Cheng go"

They should arrive tomorrow morning. We're coming in batches, but don't worry, I've had people watching over them secretly. They'll be fine.

The supplies in Sun Cheng's hands were extremely important to her. They couldn't go wrong, and they definitely couldn't fall into someone else's hands.

Get some rest. We have to go out again tomorrow.

Seeing Feng Lingxi still messing with cinnabar, it's already yawn-inducingly late and he looks exhausted. He doesn't seem to know how to rest at all.

"No time to rest, I must finish brewing the medicine tonight, waiting for use tomorrow."

Feng Lingxi endured the drowsiness, "You go to rest first, I'll sleep as soon as I finish."

Dugu Cheng looked at the realgar on the table, "Do you need my help"

"No, you should sleep first. I'll be fine in half an hour."

Feng Ling Xi raised her eyes and looked at Xiao Li and Ye Xi, "Go rest, there's still a lot to do tomorrow."

Everyone else had left. Dugu City helped spread out the blanket, watching Xi'er yawn repeatedly with worried eyes.

"Realgar can dispel poisons, reduce inflammation and swelling. It's very effective for this illness. I must finish the treatment before I can rest, or tomorrow won't be enough time."

It was rare for Dugu Cheng to hear Xi'er speak to him like this. Although he knew about these things, hearing them from Xi'er's mouth filled his heart with comfort.

"Let me help you, you teach me."

獨孤城 walked up to her and pulled a stool over to sit down. He looked at Feng Lingxi with gentle eyes, "Together, hurry up. This way, we can rest sooner."

"Aren't you tired I could sleep in a little later, but you still have to..."

"It's alright, I can't sleep well without you by my side."

Feng Lingxi's heart warmed instantly at Du Gu Cheng's words. She nodded and began to teach him. Looking at her serious expression, Du Gu Cheng's eyes became even more gentle.

The next day, Feng Lingxi came to the outskirts of Xijiao City. When Field Doctor saw her arrive, he rushed forward, overjoyed and said, "Princess Consort Chen, the medicine you gave him yesterday has healed his wounds quite a bit."

Feng Lingxi nodded, "Take me to see."

Du Gu Cheng followed Feng Ling Xi, and Zhang You and others also came over together. Following Feng Ling Xi's orders, they began to help brew medicine ointment and help treat the wounded.

Suddenly having so many helpers, it was like adding wings to a tiger for Dr. Tian. With the medicine working and their morale high, they were full of energy.

The person who had taken the medicine yesterday saw Feng Lingxi arrive and hurriedly struggled to get up. "Your Highness Princess Chen, the pain and itch on my body are gone, and the wound is no longer oozing pus."

Feng Lingxi nodded and crouched down to examine the wound.

The wound, after being treated with medicine yesterday, has redness around it and is starting to show signs of healing. It seems like her medicine is working.

I still have to do a drug trial later.

"Feng Zi Mao thanks Princess Chen for saving his life."

"Your Highness, he shares the same surname as you."

Xiao Li was astonished, Feng Ling Xi didn't expect such a coincidence either.

"You and I are destined to meet, you've worked hard."

Fengzi Mao didn't expect to share the same surname as the Princess Consort of Chen, and he felt a little embarrassed.

Seeing that his spirit had improved considerably, Feng Lingxi finally got up.

"Doctor Tian, continue with yesterday's medicine, and today we will add one more ingredient. Please follow me."

Windlingxi instructed, reminding Doctor Tian to use realgar powder. After giving the instructions, she went to check on the child from yesterday. When the woman saw Windlingxi, she cried and begged, "Princess Chen, please save my child, he's dying."

Feng Lingxi crouched down, looking at the child lying in her arms. His face was pale without any blood color, and his face was covered with red rashes. His arms and neck were also covered in rashes.

We have entered the second stage.

Has he been sleeping all day

The woman nodded, tears welling in her eyes. “It started last night. I woke up with a rash all over my body. Some of the bumps are already starting to blister.”抱了抱母妃，“Mother, it’s my unfilial son who has caused you trouble.”This time, things were probably directed at him. Dugu Yu did this, nothing more than wanting to use his name to compete for the throne....
