"Drink ......," all five men began to recall what they had drunk last night.

"To put it simply, what did you eat and drink before the onset of the disease?" Lin Ling said anxiously when she saw that they couldn't remember.

It's that well! In the footage data found by Ye Chen, the Rat King was killed and thrown into a well. Due to the fact that the murderer was dressed in a night suit, blocking the main human physical features, Yechen was unable to identify his specific identity.

"I remembered that last night, during the third watch, the child was thirsty, crying and crying for water. There was no water at home, and because there was a well not far from home, I went out and fetched a bucket of water from the well. But when I got home, I fell asleep with my son, and I didn't call them for fear of waking up the children and crying, so I drank two bowls of cool well water by myself. One of the men said with a sudden realization.

"You mean there's a problem with the well water?" said the other two men in surprise, "No, there are so many wells in our village, and so many people drink water! Everyone is fine, but there is a problem with the five of us?"

"Is it the well near the Wu family's wine cellar in Hedong?"

"Exactly. Could it be that you also drank the well water, big brother?"

"No, the villagers caught mice together the day before yesterday and lost something, so I helped find it. At the fifth watch, I found Hedong, and when I was thirsty, I drank cold water from a small bowl by the well. ”

"As soon as you say this, I also remember that on the fourth watch, I also went to the well to fetch water, and this morning I fell ill. ”

Isn't it obvious that they were all sick after drinking the well water, and the reason for the 'plague' infection was obvious? Lin Ling clapped his hands and said, "It's over! That is the problem with the well water! Everyone should stop drinking the water from that well." He walked towards Puyang Jing and Nangong Hua and said, "Without further ado, my lord, we will immediately rush to the east of the river they said and check the water of that well." ”

Obviously, the answer has been given, but a stunned-looking person opened his mouth to deny Lin Ling's conclusion, and said: "However, I have not drunk the water from the well in Hedong since last night! ”

Lin Ling fell into deep thought again, and the four men all said that it was obviously because the well water was poisonous, but this one said that he had not drunk the well water. Didn't he have an esophageal infection?

At this time, the man's lady cried and spoke. She knelt on the ground and said to her Xianggong: "Xianggong, it's all my fault... It's all my fault. The cup of tea I made for you this morning was brewed with water from the well in the east of the river... You scold me..."

"You—" The man was speechless with rage.

Through the descriptions of the five men, Pu Yangjing believed Lin Ling's conclusion. After careful interrogation, I learned that other people in the village used to go to Hedong to fetch water, but it happened that the family had stockpiled water in the past two days, so they didn't go. Some just missed the time period of fetching water last night and this morning, and after the 'strange disease', everyone was so nervous that no one paid attention to eating and drinking, while others did not go to Hedong because their home was far away from Hedong and they were close to get water.

"Report~" A guard hurriedly ran in from outside the door, knelt on one knee, and said to Puyang Jing: "Report to the prince, Commander Zhang has a letter, asking the prince and the imperial doctor of Nangong to move to the east of the river." There were also villagers infected with 'strange diseases' nearby, and Imperial Physician Tong had confirmed that their symptoms were mildly infected with 'plague', and at the same time, Commander Zhang found suspicious footprints near the wellhead. ”

"Suspicious footprints?" Pu Yangjing thought of the suspicious villager in Fuyun County, Jing Yi went to check the details and still hasn't returned, didn't he escape to this Ganquan Village, right?" With a medicine kit, you will go to other wells in the village to check if the water is infected. If they have been infected, they told the villagers not to drink the water in the well, and immediately used the antidote developed by the Nangong Imperial Doctor to detoxify the well water. ”

"Yes. "The four Imperial Physicians should arrive.

The prince is the prince, he is not chaotic in the face of danger, he is strategic, what a man! Lin Ling praised Pu Yangjing in his heart.

Ye Chen listened, his expression changed a little bit, and when he listened to Lin Ling's heart in the past, he only had the relevant content of 'Ye Chen'... But the idiot Lin Ling didn't notice that the little change in Yechen quickly returned to normal.

"Let's go, go to Hedong. Pu Yangjing said to Yechen and Nangong Hua that Lin Ling and Ye Yu were protected by two guards, and the group hurried to Hedong. Before leaving, Yechen handed them some medicine and told them to take it and throw it into other wells to purify the water. Some of the people went to Hedong with Pu Yangjing, and some went home to check their water. As for the five men who were saved, they naturally took the medicine given by Ye Chen and led the family home to treat the well water infected by the 'plague'.

On the side of the wellhead in the east of the river, suspicious footprints surround the wellhead. Zhang Zhen ordered officers and soldiers to bring up a bucket of water from the well and catch a field chicken for experiments, wanting to see if the well water was poisonous.

When the guards were fetching water, Zhang Zhen squatted down and used his index and middle fingers to test the depth of the footprints on the ground and measure the size of the footprints. Looking at the size, this is a man's footprints, but it doesn't look like a man.

"Commander Zhang, the well water has come up. Li Zhenghe Xinyu said, and then the two officials brought the bucket of well water to Zhang Zhen's face.

After hearing this, Zhang Zhen patted the dirt on his hands, stood up and went to check the bucket of well water.

At first glance, the well water is somewhat muddy and slightly reddish. He Xinyu said that the water from the well turned out to be the sweetest and clearest in the village. This well water is really weird!

"Bring the field chicken!" Zhang Zhen instructed the guards behind him.

"Yes. ”

The guards obeyed the order, brought the captured pheasant and forced it to drink the well water, and within 10 seconds, the pheasant fell.

Seeing this, Zhang Zhen motioned for Imperial Doctor Tong to come forward and take a look.

Imperial Physician Tong took the masks and gloves that Yechen had prepared for them when he was in Fuyun County, and slowly approached the field chicken, which was indeed dead. Looking at the well water in the bucket again, he smelled a faint smell of blood, perhaps diluted by the well water. "Commander Zhang, you guessed it right, it's the problem of well water. ”

"Sure enough. Zhang Zhen walked to the edge of the well and looked down, he wanted to see what was strange at the bottom of the well, but the well was very deep, and there was no bottom. The well water is poisonous, and maybe it has something to do with the rat king!

"King Jing has arrived!"

"The eldest princess has arrived!"

Seeing Pu Yangjing and Lin Ling, the guards shouted twice from afar.

Zhang Zhen, Imperial Physician Tong, He Xinyu, the guards, officers and soldiers, and the officials all lowered their eyebrows and lowered their eyes, and saluted respectfully, "See the prince and the eldest princess." (The guards were brought out by Puyang Jing from the palace, the officers and soldiers were brought out by Zhang Zhen, and several officials were brought out by He Xinyu.) ）

"Get up and speak. Pu Yangjing said, his eyes fell on the field chicken on the ground and the bucket of well water, and asked, "This water is really poisonous?"

"Back to the prince, the well water is indeed poisonous. The last general thinks that the escaped rat king may have fallen into this well. Standing up, Zhang Zhen pointed to the well.

Pu Yangjing sounded reasonable, and immediately said: "Come on, fish out this well water for this king, if the rat king really dies in this well, he will definitely fish out his corpse." ”

"Yes. "The guards got the order, found a bamboo pole, and prepared to fish.
