Before dawn, although the people at the observatory were sad, they all had the same expression. It was obvious that they all thought that Professor Lao was killed by criminals. They were thinking about how to find the murderer, and it would be best if they could shoot him as well.

However, things changed in the morning.

Chen received a call from the police station, informing them that the gang that had escaped before had been arrested the night before. The police of the two countries launched a joint operation to encircle and suppress a group of smuggling gangs and arrested many people.

Among them was the suspect mentioned earlier, but when Professor Lao was killed, he had already been controlled by the police.

Chen further confirmed whether anyone had escaped and hid in the jungle during the chaos. The other party could not confirm it, and only said that the border station had not found any traces of suspicious elements.

He also asked if there was any news about thieves recently.

The other party clearly denied it. In June this year, Southeast Asian countries signed a document to jointly protect wildlife and severely crack down on illegal poaching. The news was very intense.

A group of illegal traders who originally collected pangolin scales, rhino horns, and crocodile skins were severely arrested, and others dared not show up in the past two months.

Chen was very uneasy.

If it was not done by criminals, who killed Professor Lao last night?

He asked the police to come to investigate, but unfortunately, the surrounding police forces were all drawn to participate in this operation. There were not enough people left behind, and it might take two or three days for them to come.

The blizzard mountain villa in the tropics was born.

Compared with the environment, what is more disturbing is the cause of Professor Lao's death.

Fina repeatedly confirmed with Chen: "Could they have made a mistake? Otherwise, who shot my father?"

Chen shook his head and did not change his words.

Mrs. Lao was much calmer than her stepdaughter: "If it wasn't someone from outside, then the shooter was one of us?"

Chen looked at her and said nothing.

Reporter Li was still a little confused: "What do you mean? There are no suspicious people, so we are the suspects?" He looked confused, "We didn't join your action last night, what does it have to do with us?"

President Kang was also confused: "Didn't they encounter robbers? Who was it?"

"It could be anyone." Jian Jing said, "I think we can't rule out the possibility that criminals sneaked into the jungle and were discovered by Professor Lao to silence them, but at the same time, we who were present are also suspected of killing the deceased."

Reporter Li was stunned: "We were all in the hotel yesterday, and we don't even know where they went."

"But everyone had enough time to commit the crime." Jian Jing scanned their faces. "After the professor and his friends left yesterday, we dispersed immediately. Did you meet each other after that until they returned?"

Reporter Li paused, unable to refute.

Doctor Cha said, "I stayed in my room the whole time."

"Me too." Reporter Li added, "It was the professor who told us not to run around."

Jian Jing said calmly, "Everyone, I don't mean to accuse any of you of being the murderer. It's just that the professor died suddenly. Although it may be the work of criminals, did anyone see a stranger?"

She looked at Fina and asked, "Have you seen a stranger?"

Fina shook her head.

She looked at Chen again, "You patrol every day. Have you seen a stranger?"

Chen thought for a long time and shook his head slowly.

"Also, who of you has seen the monkey?" Jian Jing said, "I haven't seen it since last night."

Fina was stunned for a moment, as if waking up from a dream: "Yes, Polly didn't seem to follow his father yesterday, where did it go?"

Mrs. Lao frowned and said, "Come to think of it, I haven't seen it today either. Normally it would not miss breakfast."

"Now there are a lot of doubts." Jian Jing analyzed, "I checked all the Type 56s this morning. Professor Lao's gun had 9 bullets, Chen's gun had 6 bullets, and the remaining gun had 10 bullets. I want to ask, are your guns fully loaded?" "

Mine is full." Fina was embarrassed, "I haven't fired a gun since I came here."

Chen said, "I'm not."

Jian Jing: "Why?"

"Bullets are very expensive." Chen replied.

Jian Jing didn't understand, so he had to say a long string of words in his native language. Fina translated: "Chen said that the intimidation of a gun is greater than its lethality. Normally, it is not necessary to have a full magazine every minute. In case of an emergency, he will bring a handful of bullets."

"Did you shoot a gun yesterday?"

Chen shook his head.

"Do you know how many rounds the professor's gun has?"

He gestured 10 and said a string of words.

Fina continued to translate: "My father is different from Chen. He likes to use up the entire magazine in one breath, and he likes to use the Type 97 - maybe he was afraid of scaring No. 21 yesterday, so he used the Type 56. But he always brings enough ammunition, so the magazine should be full."

Jian Jing nodded slightly.

The Type 56 semi-automatic rifle fires one bullet with one pull of the trigger, but the Type 97 is an assault rifle. If you hold the trigger and don't pull it, it will keep firing, and a magazine can be used up in minutes.

This is consistent with the personalities of Professor Chen and Lao.

Bullets are expensive, and only Americans are so extravagant (crossed out).

She thought about it and said, "Fina, can you take me to the place where the professor was found?"

"I... I'm sorry, Jane, I don't want to go back to that place." Fina refused her apologetically.

"Sorry." Jian Jing paused and looked at Chen. He nodded, neither asking the reason nor questioning: "I can take you there anytime."

Jian Jing: "Anyway, there's nothing else to do now, let's go now."

She was worried that if she delayed for a moment, the clues would disappear a little.

Chen had no objection, so he picked up his gun, water bottle, and satellite phone, and told her, "The road is not easy to walk on, and we can't be back before lunch."

Jian Jing followed the advice, put on her backpack, put a leash on the rider, and prepared to take the dog with her.

However, before leaving, Kang Mucheng said he would go with her.

Jian Jing: "You should stay with the president."

"She's with Mrs. Lao, I'll go with you." Kang Mucheng glanced at Chen, and was really worried about her going into the deep forest alone with a strange man.

The rider: "Huh?"

Jian Jing patted the dog's head, and didn't have any objections.

The three of them entered the forest.

Jian Jing asked, "Are we going to follow yesterday's route, or the shortest route?"

Chen: "The fastest route."

She nodded and started timing.

Trekking in the primeval forest is much more difficult than walking on flat ground. There are small branches everywhere, which occasionally scratch the hair and cheeks. The soil underfoot is either too hard to hurt the feet or too slippery to make you fall. There are also stones and tree roots everywhere, so you have to be extra careful when walking.

Chen has already gotten used to this environment. He walks very fast. The riders use four legs to steadily outpace others. Only Jian Jing and Kang Mucheng observe the environment while walking, so they can't walk fast.

After walking for about 1 hour and 20 minutes, they finally arrived at observation point No. 3.

This is a small wooden house built in the woods. It looks plain on the outside and the space inside is very small, with only one window and a chair.

The floor in front of the window is slightly sunken and has obvious marks.

"What is here?" Jian Jing asked.

Chen said, "Camera." He pushed open the window and pointed outside, "You can take pictures of animals."

She suddenly realized and asked, "Didn't you say there are guns?"

Chen motioned for her to move aside, then lifted the floor below with his bare hands, revealing a little water, biscuits and a Type 56 semi-automatic rifle.

Jian Jing put on gloves and checked the number of bullets inside.

10 rounds.

"Is this gun always full?" she asked Chen.

Chen nodded and added, "This is a spare gun. I check it every time I come here and replenish it if it's missing."

"When was the last time you checked it?"

"The day before yesterday."

Jian Jing seemed to be thinking about something, and suddenly asked, "Where are your bullets kept? Can others get them?" "

In the safe. Only the professor and I have the key." Chen paused and said, "Fina's gun is hers. I don't know."

She nodded and began to survey the scene: "Where did the body fall?"

Chen took her outside the wooden house. There were bloodstains scattered on the open space not far away. Some flies were circling and flying, and they refused to disperse when they saw people coming. There

were footprints all around, leaves were flying, and there were also rat claws.

Jian Jing took photos from all angles, but unfortunately, there were too few valuable clues.

She could only judge the posture of the body by the traces of blood.

"Are you the first person to arrive?" she asked Chen.

Chen nodded.

"The professor was lying on his stomach?"

He made a motion of falling on his back.

"The second one was Fina, and the last one was Mrs. Lao?"

He nodded.

Jian Jing sighed. It was too difficult to question a witness who didn't speak the language. But so far, she still has a high degree of trust in Chen.

Because his gun only has 6 bullets.

If he killed Professor Lao, he probably wouldn't choose the same gun as his own, unless it was a passion killing. But at present, he and the deceased have no contradictions.

In fact, he was the first person to discover.

The conditions for committing the crime were too abundant to be worthy of suspicion.

Jian Jing pondered for a moment, then took out the monkey's small clothes from his backpack: "Knight, come."

The German Shepherd stepped forward, smelled the smell of the clothes, and showed a disgusted expression on his face.

"Find the monkey." There was no other way. The master had given the order. No matter how much he disliked the dead monkey, the knight still sniffed it dutifully.

Jian Jing picked up a wooden stick, pushed aside the surrounding grass, and checked it very carefully.

Kang Mucheng asked, "What are you looking for?"

"Another bullet." Jian Jing said, "The professor was shot twice, one of which was a penetrating wound. I want to see where the first bullet hit."

What's the difference between the two bullets? Aren't they both from the same gun?

Kang Mucheng thought about it and was suddenly startled.

He had read all her works, and often, he could tell the intention and even the mood behind a few words between the lines. However, if it happened in the current situation, he seemed to have lost something and could not understand her thoughts.

"Mr. Kang?" she wondered, "Do you want to help me find it?"

Kang Mucheng suddenly came back to his senses, nodded in response, and also looked around.

Chen looked around, sometimes squatting to distinguish footprints, sometimes searching in the bushes. After a while, he said, "No outsiders have appeared recently."

Jian Jing asked, "How do you know?"

"I have encountered them." He tried his best to organize his words. "They need food and water. They didn't move the house. They also hunted and set fires. There are no similar traces nearby."

Jian Jing stared at his simple face and asked, "So, you agree with my guess that the murderer may be someone in the observation station?"

Chen nodded.

"Who?"

He thought about it, but shook his head. I don't know if he couldn't guess or didn't want to say it.

Jian Jing spent the next hour looking for physical evidence, but he found nothing. He didn't find where the second bullet shell went.

Did the shell accidentally hit a rock and splash onto the tall treetops? Jian Jing looked up for a long time, her neck was sore, and she didn't find the shell anywhere, so she had to give up.

The knight's luck was much better.

It came running over, bit Jian Jing's trouser leg, and motioned her to follow.

Jian Jing was shocked.

The knight swiftly shuttled through the bushes, and when he saw that his master didn't catch up, he stopped and waited. His brown fur was soon covered with grass clippings.

About ten minutes later, it stopped in front of a pile of brightly colored fabrics.
