The direction is off, swaying left and right, she can still understand!

However, after hitting several cars in a row, skidding, crashing into a bridge, and almost rushing down, almost overturning, resulting in countless injuries, she is a little incredible!

As he spoke, he raised his eyes and asked, "What do you think, expert?" ”

"All contradictions are caused by external and internal causes, sometimes they work together, and sometimes they are divided into priorities", the expert said, still looking at her obsessively, but the words of the answer were quite serious, and he said slowly, "The car accident is naturally the same." ”

Tang Xiaonian frowned, began to think about his words, and after thinking about it for a while, he received a reminder message and said to him, "So, the car is fine, the bridge, there may be a problem?" ”

In general, in this situation, when there is a car accident, everyone thinks of checking the car or people, this is the point, there is no too prominent or weird situation, no one can think of making a fuss on the bridge!

This time, it didn't take more than three seconds for the answer to be answered, and the expert was quite satisfied, and said to her, "Go on." ”

This counts as encouragement.

Remind her that her son is teachable.

Tang Xiaonian knew that the answer was correct, so he was more positive, and stepped forward and said, "The internal cause of the car accident is to scramble for the steering wheel, but it is only a starting point, the beginning, and the important cause is that in fact, someone did something on the bridge in advance!" It's just that the bridge was hit and messy, and it was difficult to leave traces at all. The bottom of the car was even half destroyed, and it was hard to find something hidden......"

She said, but wondered, "But these, generally have to be tested, can be sure, after all, there are no obvious surface features, how can experts determine, or rather, suspect that the cause will be the bridge?" ”

The expert pointed to his eyes and whispered, "That's the hint." ”

Tang Xiaonian thought for a while, and finally clapped his hands, "You mean, after the burning, these few hours, I still feel abnormal...... Even a little spicy to the eye? ”

Obviously, it is caused by unknown chemicals!

"Coupled with the anomaly of the car accident, one of the speculations can be made."

The expert replied, "There are two more points, first, time. The bridge has a limited load capacity, and in order to limit the flow of traffic, large trucks or buses are only allowed to pass through from 2 to 4 p.m., so the time is specific. ”

He also gestured to the corner of the bus and put the road map, "Second, it is the location, when I came, I have instructed Qin Qing to call to check, the route of this car is to Anping County, there is only one flight a day, this bridge is the only way, so it proves that it is targeted, then, it is definitely not an accident." ”

He pointed to the side of the bridge, the most heavily hit position, "Although there are not too many traces, but the details are reflected, first of all, the bridge is not many vehicles, the speed limit, about sixty yards, passenger cars, large volume, stable weight, even if there is a direction shaking in the car, the steering wheel is unstable, and the sudden braking and sudden stop should not slide so far, but also caused a number of vehicles to collide continuously, and even the side of the bridge stone is broken half of the serious situation." ”

Combined with the smell of combustion in the air, there is a clear difference from the chemical smell of gasoline and body combustion, and the rate of sixty yards, even in high temperature days, it is difficult to cause spontaneous combustion under the self-protection system of the bus. ”

Tang Xiaonian was shocked by what he said, and admired him even more, and said to him, "In this way, you can be sure of one thing, this car accident is not accidental, it is man-made?" ”

"And, purposefully." Expert pick-up.
