Chapter 327

The laboratory composition of the sand came out quickly, and it was exactly the same as Bu Er Jing.

Qi Fei returned to Bu Er Jing unwillingly, searching back and forth on the long road, hoping to find clues about Dong Ziwu's fall.

Judging from the situation of the wound, Dong Ziwu fell while in a coma, which meant that there must have been other people around him. After all, a person in a coma could not move to Bu Er Jing by himself.

Therefore, Qi Fei determined that finding the first scene where Dong Ziwu fell would allow him to find clues about the murderer.

However, from sunrise to sunset, a whole day of searching yielded nothing.

Travelers had already appeared on the reopened Bu Er Jing. After sunset, people on both sides of the road sporadically set up tents, planning to camp for one night and continue hiking the next morning.

Qi Fei sat on the side of the road, exhausted, looking at the dots of light along the road, thinking that if it were this situation at that time, Dong Ziwu should have been rescued.

Unfortunately, Bu Er Jing was closed at that time, and the night must have been pitch black, unable to see the end.

In the years he had been a criminal police officer, he had seen many ways of dying. Dong Ziwu's death was both ordinary and desperate, just like a condensed real life.

Looking at Qi Fei's helpless appearance, Wu Shanqiu said out of the blue on the side: "Why determine that Dong Ziwu must have fallen in the bushes?"

This sentence awakened Qi Fei. The person who brought Dong Ziwu here must know the terrain here very well.

Carrying a comatose adult man, he would definitely look for the most convenient road up the mountain. Crossing the bushes was definitely not a good choice.

"There is only one road up the mountain here. According to the normal road, it takes a whole day and night to reach the place where Dong Ziwu was abandoned. The effect of the medicine on Dong Ziwu won't be so persistent. This possibility must be ruled out first." Qi Fei forced himself to stand up and continued to look around in the last ray of twilight.

He was looking down, searching, when a strong light swept over his head. He looked up, but the mountain was pitch black and there was nothing. Just as he was wondering, after a while, another strong light penetrated the bushes and swept across the mountain ridge from south to north.

"Oh, there is actually a mountain road up here?" Qi Fei understood. These were car lights. Before, he only focused on checking the Bu Er Jing section and didn't notice that there was a road that could be driven on the hillside on one side.

"Yes," the camper on the side chimed in. "This mountain road is quite hidden. You can't see it during the day. Only those who camp in Bu Er Jing will see those car lights and know there is a road above."

"Is there a road from that highway to Bu Er Jing?" Qi Fei asked.

The camper smiled: "This handsome guy, you guess why Bu Er Jing is called Bu Er Jing. Isn't it because it has no forks to walk? That is a car road. Of course, there is no road to come over."

Qi Fei looked at the hillside in disappointment. The sky had darkened rapidly, and the deep green that could still be seen had become black shadows.

Just by the light of the camping, in this pitch black, he saw a white silk hanging down from the mountain road along the hillside. At first glance, it seemed to be a road, but this "white silk" was perpendicular to the mountain road and didn't look like it was paved for the convenience of people walking at all.

Qi Fei turned on his flashlight and climbed to the hillside to examine it carefully. He saw that this white thing was a water trough poured with cement, but it was the dry season recently and there was no rain, so the whole water trough was dry and white, which was relatively eye-catching in the night.

"Cement..." Qi Fei thought thoughtfully, and suddenly quickened his pace toward the place where Dong Ziwu's footprints were first discovered.

The light of the flashlight swayed, and the mountain forest was completely shrouded in the night. Sure enough, a dry water trough was near the road. The slope here was much gentler than the previous place. Qi Fei tried to step on the water trough and found that as long as the force was appropriate, he could indeed climb up.

He held the flashlight and checked every inch of the water trough. Finally, he found a small piece of khaki cloth on the inner wall, which seemed to be torn and left behind when something slid down and was scraped by the rough cement inner wall.

Qi Fei stayed on the hillside with difficulty, looking back and forth, and suddenly had an idea.

"Brother Fei, the cloth you found on the water trough has been tested to be a nylon cloth with a waterproof coating." In the police station, as soon as Wu Shanqiu got the report, she went to find Qi Fei. "Commonly used for outdoor products..."

"Such as tents?" Qi Fei said immediately.

"Correct answer," Wu Shanqiu said. "However, there are many people camping in that place, so it's normal to have tents. It's just a bit strange that it appeared on the water trough."

Qi Fei stroked the music box on the table. In the crystal ball above, the scarecrow was smiling in the man-made snow all over the sky. This was a gift Zhong Kui gave him during the investigation of the case where Niu Yinzhu was killed in Nancheng Investment last time. At this moment, this gift seemed to have a kind of spiritual energy, which gave him a concrete imagination in his mind. The corners of his mouth rose slightly, his fingers stopped, and he said: "Let's go to Bu Er Jing to do an experiment."

The mountain wind blew the pine trees rustling, and a dummy wrapped in tent cloth was placed on the water trough.

The width of the water trough could just accommodate an adult. The smooth material of the tent cloth made the dummy slide down the hillside like a slide.

At first, everything looked very smooth. If one wanted to transport a comatose person who had lost the ability to act to Bu Er Jing, this was definitely a near-perfect method—first transport the comatose Dong Ziwu to the mountain road by car, then wrap him up with tent cloth and send him down along the hillside water trough. It was easy to abandon him on Bu Er Jing, and the rest only needed to come down and take away the tent cloth.

But when the dummy simulating Dong Ziwu was about to slide to the bottom, its feet touched a protrusion in the water trough, and the whole person flipped over from the water trough face down, directly pouncing on Bu Er Jing.

This explained the source of the wound on Dong Ziwu's face.

It seems this was the way the murderer abandoned Dong Ziwu. No wonder there were no signs of the surrounding grass and trees being crushed. It's a pity that Dong Ziwu, who was not familiar with the terrain, didn't have this imagination at all; he could also escape by climbing up the hillside.

Qi Fei looked at this not-so-steep hillside and the dummy pouncing on Bu Er Jing, and couldn't help but feel sighing. In the place where Dong Ziwu woke up, there were actually many ways to escape easily, but he missed them all.

At this time, a mountain wind blew, and Qi Fei couldn't help but shiver. He realized, when the person who abandoned Dong Ziwu was there, was he also standing by this road like him, watching Dong Ziwu under the hillside with cold eyes—did he really want Dong Ziwu to die? Or was it just a prank? In any case, he still didn't understand why he had to come to Bu Er Jing.

Just when he was confused, Wu Shanqiu on the side seemed to have discovered something. She bent down and picked up something on the side of the road and muttered: "What is this?"
