"Look where the tire tracks start," Wang Shen said, pointing to the tire tracks in front of him and then looking at the dirt road behind him.

Liang Zichen listened carefully to Wang Shen's words and observed Wang Shen's actions again. Suddenly, he slapped his forehead and realized, "That's right, it can't be borrowing a passage!"

Wang Shen stood up from the ground, took two steps back, and then explained the reason. "The tire tracks started from that side, and apart from the cement area directly in front of the house, the rest of the road is dirt, but there are no tire tracks there. And the road in front of the house is the only way to the road behind the house, so where did the missing tire tracks go? The car couldn't have fallen from the sky and landed directly on the road behind the house, could it?"

“That’s right, that tire track is definitely not the starting point. So there’s only one possibility.” As he said this, Liang Zichen took a few steps back, then squatted down and carefully tapped the dirt road in front of him.

"The murderer was probably afraid we would find some clues, so he wiped away the tire tracks in front of the house. But the murderer didn't expect that we would still discover his intentions." Liang Zichen grabbed a handful of dirt from the ground and then clapped his hands.

"If that's the case, what was the killer's real purpose in erasing these tire tracks? In other words, was the killer afraid we would discover something based on these tire tracks?" Wang Shen touched his chin, lost in thought for a moment.

"Right now, we should be able to find the answer we're looking for by following these tire tracks," Liang Zichen reminded Wang Shen.

"There's another question here: whose car is this? And where is the murderer going to drive it?" Wang Shen pursed his lips, as if asking Liang Zichen, or perhaps talking to himself.

"Alright, there's no better way right now. Let's follow the tire tracks and see what happens." After saying that, Wang Shen took a few steps forward, lowered his body, and followed the tire tracks step by step.

After walking for a while, Wang Shen suddenly squatted down on the ground, grabbed a handful of soil, and smelled it.

"Look at this." Wang Shen handed the soil in his hand to Liang Zichen.

Liang Zichen took the soil from Wang Shen's hand and examined it carefully. The color of this soil was different from the soil in other places. This soil was darker and had a reddish tinge. Liang Zichen also imitated Wang Shen and brought the soil close to his nose to smell it.

"There's a bloody smell?" Liang Zichen's pupils widened slightly as he stared at Wang Shen and said this.

Wang Shen nodded, then turned around and slowly took a few more steps forward. His eyes remained fixed on the road surface around the tire tracks. After a few more steps, he discovered a second patch of blood around the tracks.

Liang Zichen followed Wang Shen, also searching for the remaining bloodstains. After finding the second bloodstain, Wang Shen followed the tire tracks, but strangely, the bloodstains seemed to vanish. Where was the third bloodstain? Had the murderer discovered this problem and deliberately hidden the bloodstains?

Just as Wang Shen was standing by the roadside, staring at the tire tracks in deep thought, Liang Zichen, who was crouching behind him, suddenly shouted, "Captain Wang, come quick! We've found something!"

Wang Shen immediately turned to look in Liang Zichen's direction. At this moment, Liang Zichen had already squatted down, standing next to the bushes not far from the tire tracks.

Wang Shen quickened his pace and squatted down beside Liang Zichen. Liang Zichen held a stalk of wheat in one hand and pointed to the bloodstains on it with his other finger.

"Captain Wang, the bloodstains that had disappeared have reappeared on this ear of wheat."

Wang Shen nodded after looking at the bloodstains on the wheat ears and said, "It seems the murderer got off the bus here."

"Captain Wang, do you think this bloodstain is the murderer's or someone else's?" Liang Zichen frowned as he looked at the bloodstain on the wheat ears.

"We don't know yet, but I suspect that Dean Fu Ju and Han Lin's child is probably in grave danger." Wang Shen's expression was not good when he said this.

"Captain Wang, why do you say that?"

Wang Shen composed himself and began his analysis. "Think about it, if the murderer was injured on his own, why would he come here? Logically, if the murderer failed in his attack, he should have fled the crime scene as quickly as possible. If possible, he should have also destroyed the evidence."

“Following this line of reasoning, the murderer’s purpose in coming here is…” Liang Zichen paused, and his expression darkened.

"Was the murderer trying to destroy the evidence?" After a while, Liang Zichen whispered his guess.

Wang Shen didn't answer. He looked up at the sky and then took his phone out of his pocket.

"Hello, this is Wang Shen. Yes, please send some people over immediately. Okay, thank you." Wang Shen said a few words into the phone and then hung up.

After hanging up the phone, Wang Shen lowered his body, pushed aside the wheat stalks in front of him, and walked into the wheat field. Liang Zichen followed behind Wang Shen, and after walking for a while, asked, "Captain Wang, it's almost dark. Investigating at night will be difficult. How about we do it tomorrow..."

"No way!" Before Liang Zichen could finish speaking, Wang Shen decisively rejected his suggestion. Wang Shen turned to look at Liang Zichen, then took out his phone from his pocket. He tapped a few times on his phone, then held the screen up in front of Liang Zichen.

Liang Zichen glanced at Wang Shen with a puzzled look, then turned his gaze back to Wang Shen's phone screen. The screen displayed the city's real-time weather monitoring.

Liang Zichen suddenly understood what Wang Shen meant and nodded at Wang Shen.

Although Liang Zichen understood Wang Shen's meaning, Wang Shen still explained the reasons in detail. "You should understand now. Look at the weather data and the clouds overhead; it's about to rain. If we can't gather more clues before it rains, a lot of information will be buried underground with the rainwater. This will bring great difficulties to our future investigations."

After saying that, Wang Shen and Liang Zichen continued forward. This time, the bloodstains provided them with a good guide. Following the bloodstains, Wang Shen and Liang Zichen walked deeper into the wheat field.

At this moment, Wang Shen squatted down again, looking at the newly appeared bloodstains in front of him. "Zichen, look at these bloodstains and see how they differ from the initial ones."

"Huh?" Liang Zichen exclaimed in surprise upon hearing Wang Shen's question. Then, Liang Zichen squatted down again to carefully examine the newly appeared bloodstain in front of him.

At first glance, the bloodstains appeared indistinguishable from each other, all being specks of bright red. However, upon closer inspection, Liang Zichen noticed a significant change in the distribution of the bloodstains.
