I was a rookie reporter in the 00s

Lin Feng took out a map with the rooms and passages of the Experience Hall marked on it. "I carefully studied the layout of the Experience Hall and found that the place where the deceased was killed was a relatively hidden corner, and there was a ventilation duct nearby. The murderer most likely approached the deceased quietly through this ventilation duct and then committed the murder."

Zhang Wanqing suddenly remembered that when she was interviewing the players last night, one of them mentioned that the deceased had secretly left the room when the script-killing game was halfway through.

She immediately said, "This detail is very important. When the deceased left the room, he might have discovered some key clues or had some kind of contact with the murderer. We need to find that player and learn more about the situation at that time."

Fu Siyuan immediately picked up the phone and contacted the players who participated in the script-killing game last night, hoping to find the key witness. After some effort, they finally contacted the player, a young man named Xiao Chen.

Xiao Chen recalled: "I was confronting other players when I suddenly saw the deceased get up and leave the room. He left in a hurry, as if he had something urgent to do. I remember he went to the end of the corridor, where there was a small room, probably used for changing clothes or resting."

"This small room is probably where the deceased discovered the secret." Li Wei analyzed, "The murderer may be hiding in this room, waiting for the deceased to take the bait."

Lin Feng also added: "Moreover, the location of this room is very critical. It is adjacent to the hidden room where the safe is located. The murderer may have lured the deceased to the vicinity of the safe through this room and then took the opportunity to kill him."

Zhang Wanqing and Fu Siyuan exchanged a look of shock. The truth of the case seemed to be slowly emerging, yet it was shrouded in layers of mystery. They knew the next step in the investigation would be even more difficult and dangerous.

Night fell once again, and Zhang Wanqing, Fu Siyuan, Li Wei, and Lin Feng returned to the script-killing experience hall. This time, they headed straight for the small room. It was empty, save for some simple furniture and props. But upon closer inspection, they noticed some strange scratches on the floor, as if they had been slashed with a sharp object.

Li Wei squatted down and observed the scratches carefully: "These scratches should be left by the deceased. He may have found some clues here and tried to mark the floor with a dagger."

Lin Feng found a torn piece of paper in the corner of the room with a few blurry words written on it: "Truth...Danger..." He immediately realized that this might be the last warning left by the deceased.

"The deceased must have discovered some important secret here, but was killed by the murderer before he could tell others." Fu Siyuan said in a deep voice.

Zhang Wanqing noticed the window of the room was slightly ajar, revealing the pitch-black night outside. A chill sank in her heart, and she had a foreboding premonition: "The murderer might be hiding outside, watching our every move."

Just then, a cold wind blew, and the candle in the room suddenly went out, plunging the surroundings into darkness. Zhang Wanqing's heartbeat instantly accelerated. She subconsciously tightened her grip on the pen and looked around vigilantly. Fu Siyuan quickly turned on his flashlight, illuminating every corner of the room.

"Everyone be careful, the murderer may be nearby." Li Wei reminded in a low voice.

Lin Feng quickly checked the doors and windows of the room. After confirming that there was nothing unusual, he breathed a sigh of relief: "It seems that the murderer hasn't appeared yet. But we must find more clues as soon as possible, otherwise we may be in greater danger."

The four continued to search the room carefully, hoping to find more clues about the secret discovered by the deceased. Suddenly, Fu Siyuan found a note hidden under the bed sheet, which had a combination of numbers and letters written on it: "3-7-15-ABC".

"What does this string of numbers and letters mean?" Zhang Wanqing asked puzzledly.

Li Wei pondered for a moment and suddenly said, "This may be the password left by the deceased. The numbers may represent the password of the safe, and the letters may be some kind of clue."

Lin Feng immediately took out his notebook and began to analyze the password: "3-7-15 may correspond to the three digits of the safe combination, and ABC may be some kind of sequence or hint. We need to find the corresponding clues to crack this code."

Zhang Wanqing discovered some strange patterns on the walls of the room. These patterns looked like some kind of symbols or codes. After careful observation, she found that these patterns were related to the order of letters left by the deceased. "These patterns may be clues left by the deceased. The pattern corresponding to A is an arrow pointing to the left; the pattern corresponding to B is a key, which may represent opening; the pattern corresponding to C is an eye, which may represent observation."

"It seems that the deceased was using these patterns to remind us to observe and open the safe in a certain order." Fu Siyuan said.

Following the instructions left by the deceased, the four immediately went to the hidden room where the safe was located. They carefully opened the safe and found, in addition to the previously recovered documents, a CD. Attached to the CD was a small note that read, "The truth is here."

"This CD must contain key evidence." Li Wei said.

Lin Feng quickly pulled out his laptop and inserted the CD into it. A video appeared on the screen, showing the deceased secretly leaving the room during the script-killing game. He walked into the small room and pulled out a piece of paper from under the bed. It was covered in densely written numbers and words.

"These numbers and words are the secrets discovered by the deceased." Fu Siyuan said.

Zhang Wanqing noticed the expression of the deceased in the video. He looked very nervous and frightened, as if he realized that he had fallen into a huge conspiracy.

"The deceased must have found evidence of collusion between the owner of the experience center and criminals here, but before he could tell others, he was killed by the murderer." Li Wei said in a deep voice.

Lin Feng found some strange details in the video: "There are some strange stains on the clothes of the deceased in the video. These stains look like some kind of chemical. Also, there is some strange powder on his hands."

"These stains and powders may be clues left by the deceased during the investigation," said Zhang Wanqing.

The four immediately analyzed the stains and powder and discovered that they were a special tracking agent that could be used to track the target's whereabouts and activities.

"It seems that during the investigation, the deceased had realized that he might be followed and monitored, so he deliberately left behind clues of these tracking agents," said Fu Siyuan.

Li Wei realized that these tracers might be the final warning left by the deceased: "The murderer may have used these tracers to find the deceased and took the opportunity to kill him."

Lin Feng discovered some even more shocking details in the video: "The deceased's expression suddenly became extremely painful, and his body was shaking violently. This suggests that he may have been poisoned by the murderer the moment he discovered the secret."

"The murderer must have poisoned the deceased the moment he discovered the secret, and then killed him when he was unable to resist," said Zhang Wanqing.
