It took only a few seconds for the two of them to fall to roll to the end.

In the darkness, Conan noticed that Chi Feichi let go of his hand and quickly sat up, "Brother Chi? Are you okay?"

"It's okay." Chi Feichi sat up and felt his own condition, which was that his back hurt, and the back of his hand was scratched.

He was a little glad that he was used to wearing long trousers and long sleeves, otherwise it would be more than the back of his hands if he had broken the skin.

Conan tried his own watch-shaped flashlight and said helplessly, "My watch is broken."

The two sat quietly in the pit for a while, and after their eyes adapted to the dim light, they could vaguely see the surrounding environment.

Chi Feichi got up and picked up the small plastic medicine bottles scattered around him.

There are traces of excavation above the pit where they are located, but below the slope is a natural stalactite cave. In addition to the stalactites hanging above, there are also many stalagmites and stone pillars. The two small medicine bottles with wrong sounds hit the stalagmites and fell to the ground.

Conan helped Chi Feichi pick up a small medicine bottle and sat quietly waiting for Chi Feichi to bandage it.

When he thought of Chi Feichi was protecting him with his body when he was rolling down, he was inevitably moved.

His friends are good people, very good people.

Well... my friend still brings so complete things.

The alcohol used for disinfection and the disposable bandage used for bandaging. When he was picking up the bottle of medicine, he also saw a small bottle with a sticky note of "anti-inflammatory medicine".

However, he had one thing he wanted to confirm.

"Brother Chi, you threw the bottle off on purpose just now, right?" Conan actively helped tear a piece of medical tape to Chi Feichi.

"Yes." Chi Feichi took the tape and pressed the bandage wrapped around his hand tightly.

Conan was not surprised to get Chi Feichi's affirmative answer.

When he fell down, he heard a lot of things falling to the ground. He thought that the things in Chi Feichi's pocket had accidentally fallen out. But when he was helping to pick up the bottles just now, he found that the bottles landed in a mess, and did not seem to fall naturally.

In other words, Chi Feichi deliberately smashed the small plastic bottle in his pocket towards different places when it fell down, listening to the sound of the bottle falling to the ground, exploring the height of the pit, and exploring the situation below the pit.

Once again, I envy someone's real name for being calm and quick to react when encountering things.

After Chi Feichi dealt with the injuries on his hands and put the small bottle in it, Conan stood up, walked to the steep slope, looked up, "It was a hole dug manually, reinforced with cement, and built this slope, unlike for people to enter and exit or use to trap prey. The village is surrounded by mountains and is prone to disasters when it encounters heavy rain, then the hole should be used to guide rainwater into the reservoir of the natural stalactite cave, and was built as a backup reservoir."

Chi Feichi and Conan had similar judgments and reminded him again, "The wind blew from the hole above, there was no behind it, and the passage was sealed."

Conan turned around and walked deeper for a while, but was indeed blocked by a wall. He reached out and fumbled in the dim light, "It's cement..."

Chi Feichi also arrived at the cement wall, and put his palm on the wall. When his palm was pressed against the cold wall, he suddenly had a guess in his mind.

"The slope over there is too big, it's hard to climb up, and the road here is sealed by cement again," Conan regrets to withdraw his hand, "It seems that we can only wait for everyone to find it if we want to go out."

"Conan..."

Chi Feichi's lowered sound seemed a little gloomy in the pit.

Conan felt a chill on his back when he heard this, and he looked up at Chi Feichi beside him.

Because the light was too dark, he could only see a dark shadow standing facing the wall with his hands on it.

Chi Feichi didn't say anything anymore, retracted his hand, turned around and walked towards the slope of the pit, took out a multi-purpose saber from his pants pocket, turned out the screwdriver, the opener and the protractor, and used the protractor to get stuck between the screwdriver and the opener to make a stable triangle, hold the handle tightly with his right hand, "Come here."

Conan walked forward and found Chi Feichi picked him up and guessed Chi Feichi's intention, "Do you want to climb up directly? You can find a rope to pull me down after you go up. It's easier than just taking me up now?"

The tip of the screwdriver and the opening tip is stuck on the edge of the slope or pothole, and the edge of the protractor increases friction, plus Chi Feichi's physical energy and explosive power, you should be able to climb up, but crawling with a child will be much more troublesome.

Chi Feichi didn't explain and hugged Conan higher so that Conan could see the situation behind him. He stuffed a small plastic bottle into Conan's hand, "Open the lid, protect it in his hand, watch it carefully, and prepare to sprinkle it out at any time."

Conan lowered his head and opened the bottle. He saw the red chili powder in the bottle through the moonlight. He was stunned for a moment before he understood what Chi Feichi meant.

I understand, Chi Feichi means that if the weird guy ambushed at the hole after he goes up later, he will immediately sprinkle the chili powder when he sees someone...

This should also be the purpose of Chi Feichi holding him up with him - he is responsible for staring at Chi Feichi's behind him.

After Chi Feichi finished his explanation, he did not delay any longer. He held the multi-functional saber in his right hand and stabbed the cement wall with the force to climb up.

Half a minute later, the two of them got out of the trap.

The moonlight shines among the surrounding trees, and the surroundings are quiet, without suspicious figures.

Conan capped the chili powder bottle she was guarding in his hand and handed it to Chi Feichi, saying speechlessly, "Brother Chi, you are too nervous."

Chi Feichi put the bottle on and put Conan down while observing the surroundings.

What is more dangerous than accidents and difficulties is the human heart.

If the other party is squatting outside and standing behind him when he just climbs to the hole, whether it is using a knife, a stick or other weapon, he will be injured if he is inconvenient to move.

In comparison, it was not difficult to climb up with Conan in his arms. Even if something unexpected happened, he reacted faster and stabbed the multi-functional knife into the hole wall, so he could stabilize it no matter how hard he was.

Comparing the two, fools know how to choose.

Seeing that Chi Feichi did not respond to him, Conan silently complained to his friend's words, "Nervous allergies, late stage of paranoia in the victim's disease," and looked around, "It seems that guy has run away, so let's go back soon."

Chi Feichi responded casually, glanced at the direction where the weird man left, withdrew his gaze, and took Conan to the main road. When he arrived on the main road, he whispered, "Go to investigate tomorrow."

Conan was stunned and asked anxiously, "Did you find any key clues?"

He and Chi Feichi have been together all the time. If Chi Feichi suddenly found any clue, it was very likely that it was in the pit just now, and in the pit, Chi Feichi stood in front of the cement wall for a while, and suddenly called him out and could not continue without saying anything, which made his guess a lot more likely.

Chi Feichi must have discovered something at that time, but suddenly stopped. He didn't say anything and decided to climb out of the pit first. He was probably worried that the weird guy was still squatting outside the pit and hearing their conversation!

What's wrong with the cement wall?

Chi Feichi looked at the back of the village, "Mr. He Cang said on the way to the villa that there is a large reservoir behind the village."

Conan looked puzzled and his mind was spinning rapidly.

Large reservoirs, underground natural cave storage reservoirs, cave entrances blocked by cement...

"Can's face suddenly became solemn, and he was clarified, "If the reservoir is connected to the cave, there is only a gate partition in the middle, the murderer just seals the exits of the cave and leaves only a hole under the sacrifice tree. When the opportunity is right, open the switch of the reservoir gate, so that the water in the reservoir can be poured into the cave. The water in the cave will increase rapidly, but there are not enough vents to discharge air, and the air pressure will become larger and larger. Then, the air that rushes out of the hole is enough to lift people upwards and pierce into the branches in an instant..."

In this way, the strange sound that resounded through the village before Taemi Shirato’s death could be explained. It should be the sound of water pouring into the cave and squeezing the air.

"But there are no similar holes near the sacrifice tree, and it should be difficult to blow people away and accurately pierce the sharpened branches just by relying on the airflow bursting out of the hole, right?" Conan murmured while touching his chin.

Rather than saying that he was asking Chi Feichi, he was asking himself.

He also thinks this is the answer that is closest to the truth at present, but there are still many doubts that need to be clarified.

Chi Feichi was also thinking.

When he was staring at the corpse and eating bread, he evaluated in his mind that with his current strength, he could throw people into a high altitude and be stabbed to death by branches, but it was difficult for people to pierce into branches that were thick enough to hang up a person.

Similarly, it is difficult for small institutions to do this.

A small catapult machine may throw people up, but at most it can make people hit a branch, causing bones to break and die, and it is impossible to pierce people into branches.

Then, the murderer must have a large mechanism with strong thrust, but that mechanism is secret enough.

Based on this point, he was in a large underground cave and found a cement wall that sealed the entrance of the cave and completed for no more than a month. He thought of the sound of the reservoir and the sound of the entire village before the death of Bai Teng Taimi, and then he thought of this method.

Using the cave underground in the entire village as the mechanism, this mechanism is indeed large enough, and the air is also the most hidden weapon.

However, these two points Conan said do need to be considered.

"Spike Li Li--!"

The loud and sharp chirping sounded again, breaking the silence on the road late at night.

Conan was startled and suddenly turned to look at a sacrifice tree they passed by.

This sound appears...

The murderer started killing people again?

The sound passed quickly, and there was no abnormality in the sacrifice tree behind it, and naturally there were no corpses hanging on it.

"Does this voice have nothing to do with the case? Or is it that mechanism not exists near all the sacrifice trees?" Conan said, speeding up and running to the place where the sacrifice tree where the Sacred Tree where the Sacred Tree was pierced by the Sacred Tree. "It seems that there is more than one Sacred Tree in this village, but the most likely thing to be the scene of the crime is the tree that pierced by the Sacred Tree. Brother Chi, let's go and take a look!"

Chi Feichi followed.

By the time he arrived, Conan had already looked up at the branches of the sacrifice tree, but there was no corpse hanging on the sacrifice tree.

Taemi Bai Teng's body has been taken away by the police. Now the branches are empty, with dry blood at the tip appearing black in the moonlight.

The night wind blew the yellow warning belt near the sacrifice tree, and also bent the waist of the weeds in front of the tree, revealing a piece of land that was penetrated by blood and also appeared black under the moonlight.

Conan stood for a while, but he didn't know if the environment was too gloomy, things were too weird, or if it was cooled down tonight, which made him feel a little cold. He turned to look at Chi Feichi who was following him, "There is no corpse."
