"You calm down first, Xu Ling is accompanied by local police officers, I originally wanted to follow, but your phone can't get through, and there are a few times when there is no signal, so I can only wait for you here." Lao Chen said.

Xu Tian's mobile phone did receive a few text messages to remind him of the call, this situation did make Xu Tian feel a little confused, the way to the police station has always been in the city, it stands to reason that there should be no signal along the way.

"What are you thinking?" Lao Chen asked.

"Huh?" Xu Tian was suddenly stunned. "I'm sorry, let's go to the hospital now!"

"The hospital is not far from here, we just need to walk, and Xu Ling is being rescued, even if we arrive early, it is useless." Lao Chen said.

"Did Aunt Xu explain anything before she fell into a coma?" Xu Tian asked.

"No, I just informed the local police of your reasoning, and the news had just begun, and Xu Ling covered her head and fainted." Lao Chen said.

"Did Xiao Ai and the village chief know about this?" Xu Tian asked.

"I haven't informed them yet, at this juncture, I think it's better for Xiao Ai and the village chief not to move." Lao Chen said.

"What kind of poison has been found out?" Xu Tian asked.

"Before you arrived, I received a notice from the accompanying police officer, saying that it was a chronic medicine, and the specific thing has not been tested yet, but the doctor already has eyebrows, it should be a plant with toxins, most likely an edible mushroom such as a mushroom." Lao Chen said.

"Poisonous mushrooms? Is there a time period for poisoning? Xu Tian asked.

"Last night, the time was about before midnight, and the hotel salesman on night duty also testified that Xu Ling did bring back a supper from outside last night, and it seemed that she also brought back breakfast by the way, and the salesman said that Xu Ling brought back a big bag of food." Lao Chen said.

"A big bag?" Xu Tian suddenly remembered the pair of Sitong's shoes that Aunt Xu saw when she opened the door of the hotel, could it be that there was really someone in Aunt Xu's room during the period from last night to morning? Could it be Sitong? The Sitong I saw before was an illusion at all, if it was Sitong, it shouldn't have approached him quietly like this and didn't appear.

"Why are you stunned again?" Lao Chen asked.

"Oh! I'm sorry! Xu Tian apologized again.

"You don't have to apologize all the time, isn't there something wrong with your mood right now? We've been working on several cases together, but I know you're in a bad mood right now. Lao Chen said.

Under Lao Chen's questioning, Xu Tian had no choice but to tell the scene he saw in the hotel.

"What? Is there such a thing? Lao Chen said in surprise.

"That's right! It was Sitong's shoes, but I can't be sure if Sitong was in them, if Aunt Xu knew what Sitong's shoes looked like and knew that the shoes were bought by me, then it was possible to fake. Xu Tian said.

"Impossible, Si Tong is protected by our people, and Si Yan is also by Si Tong's side, if Si Tong follows us to this city, then Si Yan will not fail to report to me." Lao Chen said.

"What's going on? If it's not Sitong, it means that Aunt Xu knows about me and those shoes. Thinking of this, Xu Tian suddenly remembered the news that Aunt Xu revealed in the hospital before, Fang Lu disappeared on the boat that came, this Fang Lu has always been listed as a dangerous person by Xu Tian, and Fang Lu has been to Xu Tian's office, Fang Lu himself has an inseparable relationship with Zhinian Tai Sui, and Fang Lu's mind is not under Xu Tian, and it is very likely that someone who has the ability to design a death plan will notice Sitong's shoes.

"What are you thinking? Isn't there an eyebrow? Your look now is completely different from what you did just now, and this is the look you look like when you solve the case. Lao Chen said approvingly.

Buzzing......

Lao Chen's phone rang, Xu Tian already had an instinct to resist this voice, and every time he heard Lao Chen's phone ring at close range, he would feel that something was happening.

Lao Chen listened to the phone call with a solemn face, and finally only said the word "understand", the shorter the words, the more serious the matter, Xu Tian had already guessed a rough idea.

"It's big again." Lao Chen hung up the phone and said.

"Did the hotel attendant who was listed as a suspect have an accident?" Xu Tian said.

"I'm glad you're back to solving the case, but it's not a good thing." Lao Chen said.

"What's the specifics?" Xu Tian asked.

"Half an hour ago, the railway police arrested the waiter who wanted to escape at the train station, and before the police officer in the bureau arrived, the waiter was poisoned and died." Lao Chen said.

"Relapse and death? It won't be ......" Xu Tian suddenly had a bad premonition.

"It's the same as Xu Ling, but the waiter is deeply poisoned, and the doctor's preliminary judgment is that he has ingested more poisonous mushrooms." Lao Chen said.

"Fang Lu!" Xu Tian said. "Fang Lu is also here this time, Teacher Jin should have told you, right?" Xu Tian said.

"I already know about Fang Lu, do you think the person who hid in Xu Ling's hotel room from last night to this morning is Fang Lu?" Lao Chen asked.

"It's very likely that I can notice Sitong's shoes and find out that I bought those shoes, Fang Lu definitely has the ability." Xu Tian said.

"As soon as you say that, the police seem to have found a pair of shoes in Xu Ling's luggage, you can see if it's this pair." Lao Chen took out his mobile phone and flipped out the photo and said.

"Yes, it's these shoes, but something is wrong, Sitong has been wearing shoes on his feet, it shouldn't be so new." Xu Tian looked at the photo and said.

"That's right, at least Xu Ling knows about the shoes, whether she and Fang Lu deceive you together, or she deceives you herself, in short, these shoes are deliberately let you see by Xu Ling." Lao Chen said.

"What about those who eat? Did Aunt Xu finish the food she bought last night? Xu Tian asked.

"I didn't find anything to eat, I guess I've finished eating." Lao Chen said.

"Arson and poisoning, it's not the same person." Xu Tian analyzed.

"It's really two styles of modus operandi, but don't be too sure, after all, there is no evidence yet." Lao Chen said.

"You let me think about it, things seem to be a little too inclined to the truth, every time someone seems to deliberately guide us to the truth, and I feel that the murderer left us a lot of clues, such as Sitong's shoes, and the matter of the Tibetan people under Kang Yuliang's car, these obvious clues led us step by step to track down the murderer, and in the end we finally targeted the missing Fang Lu, don't you think it's a little too smooth? Fang Lu can fake her death seamlessly, will she show such obvious horse feet? Xu Tian analyzed.
