Although there are only clear porridge, steamed buns, and side dishes, there is a man sitting opposite to eat, and Yu Tingwei eats with relish.

"Mu Xiujin, when can I bring the expert back to the village?"

Yu Tingwei said with a whining while stuffing steamed buns into her mouth.

"After eating, Zhang Cong will pick you up, take you directly to meet them, and you will go back to Lilac Village together. ”

"That's great!"

As soon as she heard that she could take someone back after eating, Yu Tingwei sped up her meal, and stuffed a large piece of steamed bun into her mouth in one bite, but she was sad and choked, and her little face instantly turned red.

"You can't eat slowly!"

Mu Xiujin looked at Yu Tingwei's scratching of her ears and cheeks, and quickly got up and turned behind her and quickly patted Yu Tingwei's back.

Yu Tingwei slowed down for a while, and finally swallowed the steamed bun.

"Are you stupid?"

Seeing that Yu Tingwei was fine, Mu Xiujin sat down relaxedly, and glanced at someone with great disgust.

"You're stupid!" Yu Tingwei was angry, why did she always scold her for being stupid, "Why don't you say that your steamed buns choke people?"

"Well, your steamed buns don't choke. ”

Mu Xiu didn't bother to pay attention to Yu Tingwei, lowered his head and continued to eat.

Yu Tingwei pouted, feeling that this time she saw Mu Xiujin's IQ plummeting.

After breakfast, Zhang Cong was already waiting at the door.

"Hey, Mu Xiujin, where's my satchel?"

Yu Tingwei was in a hurry to leave, but she couldn't find the bag she was carrying when she came.

"Here. ”

In a hurry last night, Mu Xiujin casually cooled Yu Tingwei's soaked satchel to the balcony on the first floor, and was about to give it to Yu Tingwei at this time.

"What are you carrying in this bag, so heavy?"

Mu Xiujin frowned, and squeezed it casually, huh?

"It's nothing. ”

Yu Tingwei said a perfunctory sentence embarrassedly, and reached out to snatch the bag in Mu Xiujin's hand. Mu Xiu raised his hand, and Yu Tingwei pounced.

"Open it and let me see!"

The more Yu Tingwei was secretive, the more curious Mu Xiujin became.

"If you don't show it, pay me back. ”

Yu Tingwei was anxious and jumped high to grab it.

Mu Xiujin didn't bother to talk nonsense with Yu Tingwei, took two steps back, and took matters into his own hands.

"Hey, Mu Xiujin, it's rude for you to rummage through the girl's bag casually?"

Yu Tingwei's little face puffed up and pinched her waist to accuse Mu Xiujin.

Mu Xiujin opened the bag as if he hadn't heard it, in addition to some small daily necessities that girls usually like to carry, and some change, Mu Xiujin actually took out two bricks from the bag, and at first glance, a whole brick broke into two.

"Yu Tingwei, you ......"

Mu Xiujin weighed it one by one, and he didn't know what words to use to describe the girl in front of him.

It's unbelievable that a girl has two bricks in her bag.

"What? can't you use it for self-defense?"

Yu Tingwei's eyes were indignant, she took back her shoulder bag and straddled it directly over her shoulder.

Those two bricks were the ones that stunned Sun Peng, Yu Tingwei was worried about leaving evidence of her own shooting, so she took the bricks out, and wanted to find a place to throw them, but she forgot them in a hurry, so she took them all the way to the capital.

"I gave it to you. ”

Yu Tingwei didn't mention to Mu Xiujin about meeting Sun Peng again, just looked at the brick in Mu Xiujin's hand, and then looked at Mu Xiujin, naughtily threw a wink at the man, turned around and ran away.

"If you have any difficulties in the future, remember to call me as soon as possible. ”

Mu Xiujin said loudly at Yu Tingwei's slender back, and after thinking about it, he added, "Don't worry, this situation won't happen again." ”

"What is the situation?"

Yu Tingwei turned around and shouted mischievously, but did not stop at her feet, but continued to walk backwards.

Mu Xiu was silent, but a faint smile appeared on his face.

Yu Tingwei also smiled, turned around again and sped towards the car parked outside.

Seeing Zhang Cong driving away from the villa, Mu Xiujin walked to the flower bed and put the brick in his hand on the edge of the flower bed.

In the car, Yu Tingwei learned from Zhang Cong that the expert Mu Xiujin helped him find was Mu Xiujin's classmate, named Xu Ming, a doctoral student at Beijing University, specializing in animal husbandry.

The car sped all the way, and more than two hours later, Yu Tingwei took Xu Ming and his party back to the chicken farm.

"Xiaofeng, you can count it back, half of the chickens are going to die, and if you continue like this, they will all die. ”

Liu Qing greeted Yu Tingwei, and said with red eyes, it was obvious that Liu Qing had shed tears in the past two days when he was away.

"Don't worry, no, I've already brought an expert," Yu Tingwei comforted Liu Qing, "They will definitely find a way to cure these chickens." ”

Xu Ming is also very dedicated, and as soon as he arrived, he led his team into the chicken coop.

After some inspection and research, Xu Ming investigated the dead, sick, and healthy chickens, as well as the sanitary conditions of the chicken coop and the quality of the feed one by one, and finally came to the conclusion that it was not chicken plague, but food poisoning.

"Food poisoning?" Yu Tingwei was surprised, "How is this possible?"

"Our chicken feed is freshly fed and prepared every day, so how can it be food poisoning? And if it's food poisoning, how can only some chickens die from poisoning, not all of them?"

Yu Tingwei was puzzled, and couldn't figure it out. Not only couldn't she figure it out, but Yu Dabao couldn't figure it out either.

"Director Yu, don't worry," Xu Ming helped his eyes, and explained to Yu Tingwei with a kind smile: "This food poisoning not only refers to feed, but also may be drinking water, Director Yu thinks about it carefully, is there really no problem with your drinking water?"

"Drinking water?"

Yu Tingwei muttered to herself, frowning at Yu Dabao and his wife, as if waiting for them to help her explain.

"The drinking water is all living water that comes down directly from this mountain, and we are even drinking this water ourselves, how can there be a problem?"

Yu Dabao questioned, he was very skeptical that the expert invited by Yu Tingwei would be good.

"Just because it's living water, I'm more suspicious of the water quality, and I just did a preliminary test of the water in the chicken coop and found that there is a small amount of sodium chloride in it. Xu Ming replied with a smile again, "Imagine if someone poisons ......."

"Professor Xu, I understand!" Before Xu Ming finished speaking, Yu Tingwei suddenly realized, "Because water is flowing, if the person who poisoned is only poisoned at a certain point in time, and it happens that the poisonous water flowing down at that point in time is used by us, then the chickens that drink the poisonous water will naturally be poisoned, and the chickens who do not drink the poisonous water will certainly not." ”

"But we test this water every day, and we don't find any problems. ”

Yu Dabao still doesn't think it makes sense, although this water is living water, but after they receive it, it will be filtered and then fed to the chickens.

"So that's why I'm desperate to figure it out. Xu Ming still said to Yu Tingwei with a soft expression, "Director Yu asked me to test all the mountain spring water I received today, and then lead me to the source of the water flow." ”

"Okay, let's please. ”

Yu Tingwei believed that the expert Mu Xiujin found for herself would not be wrong, so she led Xu Ming and several other researchers directly to the ingredient room.

Yu Dabao, Liu Qing, and several skilled workers in the field also followed curiously and wanted to find out.
