After traveling through time, she took her husband to be a food doctor

"We can let the animals lick it," she said softly.

Lin Mingxuan was stunned for a moment, then understood instantly.

"Sir." He took a step closer and saluted.

"If the water is highly poisonous, there should be a lot of residue in the jar. Sir, can you let me check it first?"

"of course."

Li Xingjian handed the jar to Lin Mingxuan, who took it, sniffed it closely, and handed it back to Ding Xirui. Since the jar was already dry, Ding Xirui only vaguely felt a strange smell, and he didn't know if it was a psychological effect or a fact.

"Sir, can we find an animal and let it lick the inside of the jar to see how it reacts?" Lin Mingxuan continued.

"That makes sense." Li Xingjian nodded.

"Sir, I will go find a sheep right away." Ling Junsheng bowed and walked out of the courtyard. Not long after, he came back with a lamb, and Ding Xirui's uncle followed behind him, looking reluctant.

Ding Xirui also felt reluctant. It was her idea. If an animal really came to her, she would want to back out. The lamb was born not long ago. It was lively and cute. It was white and looked at everyone with its big eyes. It shrank back to its uncle in fear.

"I'll go prepare some salt water." Ding Xirui said.

If the sheep shows signs of poisoning, give it some salt water to promote excretion, and it should be able to be saved with timely treatment.

Ling Junsheng placed the jar in front of the sheep and put some grass in it. The lamb just ate the grass but did not lick the jar.

"Sir, rinse the jar with water and then mix it with the hay, and it will eat it." Uncle Ding Xirui said hesitantly.

"it is good."

"Then the little man goes home to get some fodder."

At this time, the runners finished searching the house, but found no poison or poisonous weeds. Just in case, one runner also checked the compost pit in the yard, but found no grass or leaves in it.

Uncle Ding Xirui came back, and the hay was quickly mixed. The lamb ate happily, not knowing what it was eating. Everyone stared at the lamb as if it were a rare animal. Shen Daniu was very nervous and kept praying, hoping that the lamb would be okay.

However, something soon became wrong with the lamb. It started to get impatient, and its body became a little unstable. After a while, it even started to twitch.

"Mingxuan, hold the sheep. Uncle, pry open the sheep's mouth." Ding Xirui shouted and picked up the bowl of salt water to pour it into the sheep's stomach.

"Sir, the water in that jar is indeed poisonous!" Zhao Duotian shouted.

"Sir, I am innocent. I drank the water in the jar. I don't know how it became poisonous..." Shen Daniu shouted and kowtowed.

"Dad, how can you be so cruel!" Shen Daniu's son burst into tears and fell beside his mother and cried again.

"I...whether you believe it or not, I didn't harm your mother anyway! The sun was strong in the morning, and I, your father, was thirsty, but your mother didn't bring any water. I asked her to go home to get some, but she refused. So I had to come back by myself, and I was kind enough to bring her some water to drink..." Shen Daniu's chest was heaving, and he was furious.

"Shen Daniu, did you see Shen Liushi drinking the water with your own eyes after you delivered it?" Li Xingjian asked.

"Sir, I don't have any. I put down the pitcher, poured myself a bowl and drank it, then went to work in the fields."

"Zhao Duotian, have you seen Shen Daniu drinking water?"

"Sir, I didn't. When I was resting on the ridge of the field, I happened to see Sister Liu drinking water. I didn't see anything before that."

Li Xingjian paused, then turned to Shen Daniu and shouted:

"Shen Daniu, did you pick some poisonous weeds and secretly put them in the jar?"

"Sir, I really didn't! We usually pull out the grass in our fields as soon as we see it. There are very few ordinary grasses, and I have never seen poisonous weeds. Sir, although I often quarrel with the child's mother, we have been arguing for so many years, and I will never harm her." Shen Daniu said, and bowed his head again.

"But my mother is gone! Dad, she died after drinking the water you brought her. What on earth is going on..." Shen Daniu's son wiped away his tears.

"I..." Shen Daniu glanced at his son, stood up and rushed towards a tree in the yard.

"Stop him quickly!" Li Xingjian shouted.

It was too late. With a "bang", Shen Daniu's head hit the big tree in the yard heavily, and he fell to the ground.

Lin Mingxuan and Ding Xirui hurried over and saw a large purple bruise on Shen Daniu's forehead. His eyes rolled up and he looked like he was about to faint.

"Shen Daniu!" Ling Junsheng shook him.

"Captain Ling, stop it now!" Ding Xirui didn't care about anything else and knocked his hand away.

"Dad!" Shen Daniu's son rushed over.

"Don't touch him!" Lin Mingxuan stopped him. Ding Lin and the others slowly helped Shen Daniu and laid him flat. "Sir, please untie the rope on his hands, otherwise, it will affect the circulation of qi and blood." Lin Mingxuan requested.

"Hurry!" Li Xingjian signaled Ling Junsheng to untie it.

Shen Daniu lay quietly on the ground, and after a moment, he slowly opened his eyes.

"Oh God, why don't you let me die!" Shen Daniu struggled and wanted to stand up and continue hitting the tree.

"That's enough!" Li Xingjian came up to him. "What are you doing, a grown man? The case hasn't been solved yet. Are you trying to threaten me by looking for a way out?"

"Sir, I dare not." Shen Daniu trembled and knelt down again.

"Doctor Lin, is Shen Daniu in good health?" Li Xingjian asked.

"Sir, his head hit the tree hard just now. He may be dizzy and vomit. We need to continue to observe him."

"Captain Ling, send two men to watch him here. Zhao Duotian, lead the way. I want to go to the fields to take a look."

"Yes."

Lin Mingxuan stayed behind to look after Shen Daniu, while Ding Xirui followed the yamen people to the fields. That place was near the small hill that the Ding family climbed in the afternoon. The place where Shen Liu died was near the path at the foot of the mountain. It had been trampled into a mess, with the grass leaning here and there and footprints everywhere, making it a mess.

Li Xingjian pushed aside the fallen grass, looked carefully, and looked around, but did not find anything unusual.

"Doctor Ding, I don't think there are any poisonous weeds around here. Please come and confirm it," he said.

"Yes." Ding Xirui had already followed Li Xingjian's observation, "Sir, the grass around here is indeed ordinary grass."

"Sir, in my opinion, Sister Liu was killed by Shen Daniu. I once saw Shen Daniu having a secret meeting with the village widow Huang..." Zhao Duotian said.

"What? Why didn't you say so earlier?"

"Please forgive me, sir. Shen Daniu's son and daughter-in-law were just here. I don't want things to be too embarrassing..."

Li Xingjian sighed.

"Junsheng, take people to find Widow Huang, avoid Shen Daniu's house, and bring them directly here." Li Xingjian ordered.

"Yes."

"Others, look around to see if there's any suspicious grass."

"Yes."

A gust of wind blew, and a strange smell drifted over. Ding Xirui frowned and looked up.

"Sir, there seem to be poisonous weeds on this hillside," she said.

Li Xingjian and his group looked up.

"Sir, this piece of hilltop is under the care of Shen Daniu's family." Zhao Duotian said.

"In that case, let's go uphill and look for it."

"Yes."

Ding Xirui walked up the hillside. The strange smell became stronger and stronger. Finally, she found a few poison hemlock plants behind some tall grass. The hemlock plants seemed to be protected by tall grass around them.

"Sir, there are poisonous weeds here!" she shouted.
