At this moment, Jiang An squatted on the ground, frowning, observing the chaotic traces of fallen debris on the ground.

Wan was half-kneeling beside him, cautiously measuring every suspicious mark with a tape measure.

Meanwhile, Chen Biao and several other team members formed a circle, discussing with heavy expressions.

Chen Biao rubbed the newly emerged stubble on his chin, beads of sweat forming on his forehead.

He repeatedly examined the area in front of him, gradually realizing the severity of the problem far exceeded expectations.

Finally, he broke the silence, his voice deep and cautious: "Mr. Jiang, are you saying... from this height, it's impossible for these bark falls and debris marks to be caused by a heavy-duty truck?"

Jiang An slowly stood up, dusting off his knees.

His deep eyes were as sharp as a hawk's, tightly focused on the faint clues on the ground.

"That's right,"

His voice was firm and strong, "Given the measurement at this height, the damage can only reach the level of a regular car's chassis."

Then, he squatted down, lightly tracing a noticeable scratch with his fingertips, "And even... I think it's a few centimeters lower than a regular car's chassis."

Speaking, he stood up, gesturing a height with his hands: "As for the trucks, from my understanding of these vehicles..."

He paused slightly, his gaze sweeping over everyone present.

"Their chassis height certainly won't be lower than one meter."

"This data, we have detailed records in previous cases."

Chen Biao nodded thoughtfully, "Indeed, although we haven't specifically measured truck chassis parameters, based on daily experience, your hypothesis holds up completely."

After a brief pause, he said, "So it seems... we may have misjudged from the very beginning."

At this moment, Wu Bin, who had been silently observing, suddenly stepped forward.

"Mr. Jiang, Mr.

Chen, is it possible there's another special situation? Like not here..."

Chen Biao decisively raised his hand to interrupt him: "In the current situation, we can basically rule out other possibilities."

He turned to point at the mountain road behind him, "We've already checked all four sides of this mountain."

"The roads in the east, south, and west directions showed no sign of brake marks, and the vegetation by the roadside is all intact."

He bent down to pick up a piece of flattened wild grass, "Only the marks here... Whether in direction or level of destruction, perfectly match."

Jiang An nodded in agreement, removed his gloves, took out his cell phone, and dialed a number.

At that moment, Wang Yang felt the vibration from his phone in his pants pocket.

He took out the phone, and the words "Jiang An" were flashing on the screen.

"Hello?"

"Mr. Wang, we have a major breakthrough on our end."

Jiang An's voice came through the receiver, with a hint of urgency.

"After more detailed site inspections, we found the perpetrating vehicle is likely not a heavy truck, but a small car, or even a sports car with an exceptionally low chassis."

These words were like a heavy hammer, hitting Wang Yang's heart hard.

Then, he walked out of the interrogation room, instinctively looking around, the empty corridors illuminated only by the faint glow of the emergency lights.

He lowered his voice, "What? Are you sure?"

"This is no joke."

"Mr. Wang, I'm serious!"

He took a deep breath, his voice sinking, "I naturally trust your professional judgment, but this conclusion is indeed too subversive."

"Suddenly changing from a truck to a car means our preliminary investigation direction might have been wrong."

The phone conversation fell into a brief silence, only the sound of their breathing audible.

After a while, Wang Yang finally spoke, each word like being squeezed out through his teeth.

"This matter is of utmost importance."

Though it was only a short sentence, the shock and gravity conveyed through it made Jiang An fully understand his meaning.

"I understand your concerns."

Jiang An's voice grew more resolute, "Although traffic accident investigation is not my main field, the principles of physical evidence identification are the same."

"This time, I paid special attention to several key points: firstly, the collision position is exceptionally low, with obvious metal scratches at only 20-30 centimeters above the ground."

"Secondly, analysis of the crushed grass marks indicates the instantaneous speed during the accident was at least 80 kilometers per hour."

Wang Yang unconsciously gripped his phone, his knuckles turning white.

He heard Jiang An continue to analyze, "The most crucial evidence is the grass leaf fracture pattern."

"Due to the high chassis of a truck, it causes widespread flattening when running over."

"But the grass leaves on-site show local, explosive fractures, especially with numerous neat sectioned cuts at the tips, clearly caused by a low-bottom vehicle speeding by."

Wang Yang felt a wave of dizziness, and had to lean against the wall.

All the clues spun wildly in his mind.

If it's really as Jiang An said, then they might have been misled from the start.

"Mr. Wang? Are you still listening?"

Jiang An's voice pulled him back to reality.

"I am."

He suddenly realized that this seemingly simple traffic accident case might be hiding a more complex truth.

And the two suspects they had been monitoring for a week in the interrogation room might truly be unrelated to the case.

This thought made cold sweat burst out across his back.

At this moment, Wang Yang's thoughts surged like tides, intertwining and colliding with countless possibilities in his mind.

"Could there be other hidden truths in this case that we have yet to uncover?"
