"The speed of sound propagation is 340 meters per second. When the explosion happened just now, there was a slight difference in their reaction speed." Han Chen said.
With just these two words, Su Mian immediately understood. Ding Jun frowned, also showing an expression of understanding. Xu Sibai looked calm and silent. Obviously he had already thought of it.
Time was running out, so Han Chen didn't explain too much. He helped Ding Jun, and the four of them trotted forward. At the same time, he said to Su Mian, "The woman who heard the explosion was the first. I clearly remember that she had bowed her head before we heard the explosion. So She was the closest to the explosion, which should have been on the minus floor and near the edge of the mall."
Su Mian nodded and couldn't help but turn her head to glance at his profile. This man is always smart and sharp beyond your imagination. Sound, light, whoever solves a case will pay attention to these things. But in his eyes, these all became important clues.
"Zhang Fucai, Ji Zichang, He Yayao, He Jinglun. These four people are on the third floor with us." He continued, his voice was low and clear, "When the explosion happened, their reaction was more than 1 second later than ours. This distance, vertical It is impossible to do it. Only the lowest level of the three floors, which extends farther horizontally, and the position by the river, can do it.”
Su Mian understood it completely, but she still had some doubts: "What about the person in the middle? That old factory manager Zhou Fengmao?" How did Han Chen know that he must be on the second floor, it was amazing.
Unexpectedly, Han Chen replied indifferently: "This is blind."
Su Mian: "Huh?"
Xu Sibai, who had always been silent by the side, suddenly glanced at him. Su Mian immediately understood the expression on his face - even Xu Sibai couldn't understand what Han Chen said just now.
The passage in front was still dark, and there was still no sign of harmony and friendship between the two men.

five minutes later.
Ahead, is a women's clothing area. The lights are still dim, and from the outside, it has been completely decorated. The ground is white and shiny, the logos of almost all brands have been decorated, and many stores are even filled with plastic mannequins. It looks like it's about to open.
It's just that at this moment, in the eyes of the four of them, there is naturally a kind of eerie feeling.
Having reached the area where the victims might be imprisoned, Han Chen raised his eyes and looked around, then looked down at Su Mian: "Where are they most likely to be hidden?"
Su Mian answered simply, "Zhang Fucai, the women's toilet."
The three men were startled at the same time, and Su Mian explained, "There are only three places where there is water in the shopping mall: cisterns, children's swimming and entertainment areas, and toilets." She shared her reasoning, why the first two were excluded. Then he continued: "Then only the toilet is left. L's appearance may look mature, but his essence is as naive and naughty as a, and he likes to make fun of his performance. Therefore, Zhang Fucai, a man he absolutely despises, is imprisoned in The women's toilet is more in line with his liking."
—
With a "bang" sound, another door was pushed open. Under the dim emergency light source, Su Mian looked at the empty women's toilet cubicle, her brows furrowed.
How could this be
no. Zhang Fucai is not here. This inference she was supposed to be sure of, but she was in vain.
"Let's go." Han Chen took her hand and went out the door. His face was somber, and Su Mian also pondered.
As soon as they went out, they saw Xu Sibai and Ding Jun walking towards each other. Although Xu Sibai was cold, he was considerate to the injured. At this moment, he supported Ding Jun and made Ding Jun lean on him. Fortunately, Ding Jun is also a man. Although his face is always not good-looking because of the injury, he walks and runs closely with his teeth.
"There's no men's room either." Ding Jun shook his head at them. Xu Sibai stared at Su Mian with dark and gentle eyes.
The four stood at the intersection of the passage. Su Mian looked down at her watch and saw that 9 minutes had passed since l announced the start time.
"What should I do?" Ding Jun was a little worried. "There are no clues, and no one has been found yet."
"No, there is a clue." Su Mian raised her head and looked at the three of them, "I didn't find it in the women's toilet, but it was also a clue - I thought they were hiding their victims according to their preferences. But now I have verified that they are not. They hid the victims according to another set of standards, another principle and basis. As long as we find out what it is, I believe we can find all six victims in one go."
Ding Jun's eyes widened: "That makes sense! That's what it is!" Xu Sibai was silent, his brows furrowed, as if he was thinking. Han Chen turned to look at her, and Su Mian also looked at him. Both of them saw the dark waves in each other's eyes.
"Since I've searched all the places that 'should' have water..." Han Chen said, "then he's in a place that 'should' have water, but now there is water."
"What place is that?" Su Mian asked softly.
"There is only one possibility." Han Chen replied.
—
The city is on a main road that runs eastward to the Han River.
12:00. Half an hour has passed since Peninsula Plaza was hijacked.
Police cars were blocked on the crowded Second Ring Road, unable to move. Nagging irritably gripped the doorknob with his fingers, almost fidgeting.
"Why is it so blocked? Why is it so blocked?" He glared at the cold face of the driver, "Fuck you can't think of a way? What kind of broken route did you choose? Boss and the others are now uncertain, whether it is life or death! Mom~ we still have Traffic jam here! I really want to jump out of the car and run over there! Is there any way you can!"
"Shut up!" Leng Mian was rarely angry, and Jun's face was tense. He even said a long sentence in a rare breath: "If you are noisy again, get out of the car! This is the only way to cross the Han River, there is no choice!"
Nagging also knew that he was too anxious, but he was unwilling, so he was more like an ant on a hot pot, and the probe came out of the car window again, as if talking to himself and complaining: "Let's go! Hurry up and go. Why don't you move, what the hell..."
He coldly ignored his irritability, his dark eyes stared straight ahead, and took out his mobile phone: "Hey, I'm the Black Shield Group. Why is the Changqing section of the Second Ring Road blocked? We are on a mission!"
The traffic control department responded immediately: "Police officer, two kilometers ahead, the water pipe burst and is being repaired. There has been a lot of traffic on this section, and we have no choice. We are trying to evacuate and divert..."
The cold face turned cold again.
Then he immediately hung up the phone, unbuckled his seat belt, pushed the door and got out of the car: "Nagging! There is a subway station 2 kilometers ahead, run over there!"
Nag immediately responded and followed behind him. The two, who were also wearing black police coats, ran at full speed, almost like the wind, through the traffic and the crowd, without looking back.

underground.
"There is someone here!" Xu Sibai's cold voice sounded.
The three of Han Chen raised their heads at the same time and looked in his direction.
This is another small corner of the construction site still under construction in the underground mall, roughly on the edge of the women's clothing area. Compared to the renovated mall, it is as simple as the place where they fell. There is a yellow light bulb hanging on the earth wall, just one, illuminating the cave-like construction site of Nuoda. Reinforced columns with tree roots stand on the ground, and a shallow layer of water seeps out of the soil, which is turbid, just in line with the conditions in the picture.
After Su Mian and Han Chen made their own reasoning just now, the answer was obvious. If it is said that there should be no water, it is a construction site that is still under maintenance. Because the waterproofing and other measures have not been done well, there may be groundwater seepage.
So they found it here based on the maintenance point temporarily marked on the floor plan.
It's just that it's wet and wet everywhere, just like a swamp. There is also a "dangerous" sign next to it.
The four of them split up and searched silently. At this moment, Xu Sibai was standing in front of the farthest corner of the wall, with steel bars and wood piled up beside him, blocking everyone's sight.
"Save me, save me! Are you comrades in the police! Hurry up and save me!" The man apparently saw Xu Sibai as well, his hoarse and anxious voice sounded, and he almost cried with joy.
Su Mian was overjoyed when she heard this voice, and ran over to Han Chen. Ding Jun limped and followed closely behind.
It really is Zhang Fucai!
