"Almost, we should go back too, it's better to be on time for the next village tomorrow morning, we can't afford to delay." Teacher Jin said.

"By the way, the place called Caogang Village that Xiao Ai said, Li Suqing is trying his best to deny it, is that really the place where Xiao Ai was born?" Xu Tian asked.

"I said yes, then it must be, are you doubting my cognition?" Xiao Ai said.

Xiao Ai's unfriendly answer startled Xu Tian, and at this time, Xiao Ai seemed to be in a very bad mood, as if she was angry.

"Wait...... Don't move! Teacher Jin stretched out his arms and blocked everyone.

There was a rustling sound in the grass, it was a black object walking in the grass, and suddenly that thing pounced on Xu Tian, at first glance, it turned out to be a puppy.

The puppies are followed by many different breeds of dogs, but these dogs are very difficult to identify breeds and all look like the fruits of different breeds.

"It's all skewers!" Teacher Jin said.

"I remember Lao Li said that he matched different breeds of dogs at home, and this incident may also have something to do with the secrets of Lijia Village." Xu Tian analyzed.

"But I haven't seen any of these dogs, and there were no of them in the dog factory yesterday." Yang Qi said.

"It may be the dogs that those men put at home, we also saw a litter of dogs next door to Lao Li, and now the group of dogs in front of us doesn't look too big." Xu Tian said.

When the dogs saw Xu Tian and them, they all gathered around, some lying on their stomachs beside the four people, and some staring at the four people with their tongues stretched out and their poor big eyes, as if they were begging for food.

Xiao Ai took the lead in putting down the backpack and took out all the dry food, and then Xu Tian also put down the backpack and took off the coat on his body to put the dry food.

The dogs all pounced on the food when they smelled it, scrambling to eat the dry food.

While the dogs were grabbing food, Mr. Jin took out a large pot of water from the travel bag, and there was an iron fist that Mr. Jin used to eat, Mr. Jin poured the water into the iron fist, and soon the dogs came over to lick the water and drink.

The four of them looked at the appearance of these little guys eating and drinking, and their inner anxiety was also slightly calmed, especially Xu Tian, who seemed to have forgotten about the case, Xu Tian really didn't have time to enjoy such tranquility these days, and for Xu Tian, this kind of scene of watching the dogs eat and drink water was also a luxury.

After eating and drinking enough, the dogs waged their tails and ran in the direction of the village, which made Xu Tian and them very puzzled.

"They came out looking for food, and they didn't want to escape from the village." Xu Tian said.

"Dogs are very loyal, and it seems that our thinking is wrong." Teacher Jin said.

"Yes! What if you rescue them? For this group of dogs, being around their owners is the best thing to do, even if they are not dutiful. Yang Qi said.

"I said you're not done? The dogs are already well fed and drunk, and it's time for us to do what needs to be done, and we have a lot to do sooner! Xiao Ai said angrily.

Teacher Jin suggested following the trail of the dogs back to the village, which is indeed a good way, these dogs who grew up in the village will certainly not be the first time to escape in search of food, and their route may be safer.

After tracking, the four people came to the back of the dog factory, which turned out to be connected to this wasteland, and the backyard of the dog factory was also used as a sign to draw a line with the neighboring village.

The back wall has cracked, a large part of the wall has collapsed, and the dogs have escaped from those vacant positions that have collapsed, although Xu Tianneng is sure that those dogs must be able to climb over the high wall, but judging from the grass on the wall, it should not have been trampled on by the dogs.

"What kind of grass is on the wall? It doesn't seem like a common wallhead. Xu Tian said.

"I'll see!" Teacher Jin stepped forward, grabbed a handful of wall grass and sniffed it. "This is not an ordinary wall grass, but a poisonous weed, and it stands to reason that it should not grow on such a wall, unless someone deliberately sprinkles the seeds of poisonous weeds on the wall."

"I see, could it be that some of the dogs in the village are poisoned by poisonous weeds on the wall? That's why no dog has trampled over the wall now. Xu Tian analyzed.

"You have a point, but I think it's a bit far-fetched." Teacher Jin said. "First of all, dogs are not herbivores, and in general, if they are not very hungry, no dog will run up the wall and gnaw on weeds. There is also this chronic poison can not directly poison the dog to death, no dog will die after eating poisonous weeds, although the IQ of the dog is relatively high in animals, but there is no kind of judgment like humans, as long as no dog eats poisonous weeds and dies, there should be no other dog can distinguish these grasses as poisonous weeds. So the poisonous weeds at the head of the wall were not trampled, and there may be other reasons. ”

"You've got enough of it! Does something very simple have to be so complicated? Xiao Ai sarcastically said on the side.

"Then Xiao Ai knows the reason?" Yang Qi said suspiciously.

"If you want to go in and out of the dog factory, with high walls and low bricks that have collapsed, do you choose to step on the bricks or climb over the walls?" Xiao Ai said as he stepped on the ground and turned his head and walked into the dog factory.

Xu Tian, Teacher Jin and Yang Qi instantly felt hot on their faces, yes! Why is it so complicated to think about such a simple truth?

"Xu Tian may be too tired, after all, the authorities are confused, and the bystanders are clear!" Teacher Jin lit a cigarette and said.

"Humph!" Xiao Ai showed a very disdainful look, and seemed to mock Xu Tian and Teacher Jin again.

"Teacher Jin should be an occupational disease! I'm used to analyzing complex cases, and I feel a little awkward when such a simple truth is in front of me, ahaha......" Xu Tian said.

"Don't give each other a round, come in and see! The backyard and front yard of this dog factory are not interconnected! Xiao Ai said while standing in the dog factory.

Xu Tian and the three of them hurriedly followed Xiao Ai's footsteps into the dog factory, and the building in the backyard of the dog factory looked like it had been blackened by thick smoke.

"This must be a plant that processes dog meat, and it seems that they use a very primitive method, which is to boil the stew directly in a pot with firewood, rather than using a machine to process it." Teacher Jin said.

"The method is a little simpler, but the processed food can't be stored for too long, it seems that their previous business is still very good, and the sales must not be small." Xu Tian said.

There was a two-story small building, the appearance was not blackened by thick smoke, Xu Tian judged that it should be an office building, so the four of them walked into the dusty small building together.
