Qin Yuan looked through the documents and found that the resumes of the resigned employees were marked with work records of several key departments. Combined with the recent threats, he had roughly outlined a clue.

"This is not direct enough," Qin Yuan said, calm but decisive. "The other party's purpose is very clear, which is to make you surrender through threats, but we need more conclusive evidence for who is behind them and how to operate them."

"I know." Zhou Hong nodded, but frowned, "But the other party is too cunning and completely hidden in the dark. My biggest worry now is that they will attack my family. In the past few days, I have let my parents and brother move to other places, but I am always worried."

"Do it right." Qin Yuan's eyes were cold and sharp, "The other party's goal is obviously you. As long as you don't compromise, they will likely take more extreme measures. Do you have a bodyguard?"

"Yes, security has been strengthened." Zhou Hong replied, "But I know that these people are not ordinary gangsters. Their methods are very professional, and the role that bodyguards can play is limited."

Qin Yuan nodded and said in a deep voice: "From now on, I will help you deal with this matter. The first step is that I need to check the internal monitoring records of your company, as well as the security arrangements around the parking lot and your home to see if I can find more clues."

When Zhou Hong heard this, she had a little more relaxation and trust in her eyes: "Thank you, Instructor Qin. I knew that only you can help me solve this problem."

Qin Yuan immediately launched an investigation. He started from within Zhou Hong's company and retrieved the surveillance video of the parking lot. After several hours of repeated viewing, he found a suspicious van. The car wandered around the company's parking lot several times, but each time quickly left after a few minutes.

"There is something wrong with this car." Qin Yuan pointed to the vehicle in the picture and signaled Zhou Hong to pay attention, "Have you seen it?"

Zhou Hong shook her head: "No. This should not be our company's car."

Qin Yuan nodded, recorded the license plate number and sent it to the police. At the same time, he contacted a veteran comrade-in-arms whom he was familiar with and asked the other party to help check the background of the car.

Then, he visited the surveillance point near Zhou Hong's home and found a man in a courier uniform appeared near Zhou Hong's home many times, but he did not seem to have the action of delivering the express. Qin Yuan keenly realized that this might be the other party scouting the site.

"Mr. Zhou, you must be mentally prepared." Qin Yuan said in a deep voice, "The other party is not just intimidating you, they are looking for an opportunity to attack you."

Zhou Hong's face changed slightly, a trace of fear flashed in her eyes, but she was soon replaced by calm: "What should we do?"

"Now they are in the dark, we are in the brightness." Qin Yuan's eyes were like a knife, and his tone was a little cold, "Since the other party wants to play, they must show their true face. Next, we have to lead them to appear on their own initiative."

"Turn them to show up?" Zhou Hong asked in confusion.

Qin Yuan nodded, and a sneer appeared on the corner of his mouth: "Yes, set up a game."

Qin Yuan sat in the conference room, spreading the emails provided by Zhou Hong and photos of the scene sabotaging them, and carefully checked them one by one. His eyes were sharp, as if he was capturing the subtle clues. A few minutes later, he opened a threatening email and said in a low tone: "The content of these emails is very accurate, not like ordinary intimidation."

"Accurate?" Zhou Hong asked in confusion, "You mean..."

"The content mentioned in these emails not only includes your company's specific business decisions, but also your itinerary." Qin Yuan pointed to a few words in the email and continued, "For example, this sentence - 'Your recent cooperation meeting is already an open secret', which means that the other party has mastered part of your itinerary, and only the core personnel of the company should know this information."

Zhou Hong's face changed slightly and she immediately responded: "My itinerary is indeed rarely leaked, and only a few company executives and assistants know about it."

"That means even more." Qin Yuan put the email aside and picked up a photo of the scene's destruction - a car's windshield was sprayed with red threatening words. "There is a detail here. You see these words, they are sprayed casually, but the handwriting is clear, as if someone has finished it at close range."

"So what?" Zhou Hong asked with a frown.

"This shows that the other party is not only familiar with the situation of your company, but also knows the security guards' patrol breaks here, and can calmly complete the damage and leave. In other words, this is something that only people who are familiar with the internal processes can do." Qin Yuan analyzed calmly.

Zhou Hong frowned, with a hint of anger in her tone: "You mean, maybe someone in the company is cooperating with them?"

Qin Yuan nodded in a low tone: "Behind the intimidation emails and vandalism, there is a great possibility that internal leaks are caused. The other party not only grasps your itinerary, but also knows the internal processes of your company, and may even obtain some key details of business decisions in advance."

"This is strange." Zhou Hong stood up, his tone with a little anxiety, "My executive team has been very stable. We have worked together for many years. It's hard for me to believe that someone will betray the company."

"Trust is a good thing, but the current situation is enough to make us more vigilant." Qin Yuan's tone was still stable, but it had unquestionable power. "If it is really an internal leak, we must catch this inner demon next to further investigate the mastermind behind the scenes."

"How do you find it?" Zhou Hong asked anxiously.

Qin Yuan thought for a moment and said, "We can set up a trap, release a fake message, and observe who will leak this information. When the other party contacts the forces behind the scenes, we can find clues."

Zhou Hong was slightly stunned, then nodded: "This method is worth trying. I will cooperate with you, what do you need?"

"I need you to pretend to be ready to announce an important cooperation news to the public, involving the company's core assets." Qin Yuan continued with a sharp look, "At the same time, choose a team of executives you trust the most, and inform them of the news privately to ensure that only a very small number of people know."

After hearing this, Zhou Hong expressed her solemn expression: "I understand. Then I will convene executives tonight to hold a small meeting and release the fake news using the excuse of cooperation negotiations."

Qin Yuan nodded: "This is the best. At the meeting, remember to be cautious, so that they feel that this information is very important and confidential."

"I understand." Zhou Hong's eyes were filled with a hint of firmness, "What's next?"

"Next, we need to monitor emails and communication equipment." Qin Yuan's eyes were cold, "You can use the technicians I trust to assist the police in setting up technical monitoring and observe whether anyone contacted the outside world privately."

Zhou Hong nodded: "Okay, I'll make arrangements right away."

That night, Zhou Hong convened an urgent executive meeting. The content of the meeting was false - the company is about to cooperate with an international company, and the transaction will involve Zhou Hong's most important core assets and will be officially announced in a week.

During the meeting, Zhou Hong's expression was as professional and calm as ever. She emphasized to all executives that the confidentiality of this transaction is crucial and no leakage is allowed.

After the meeting, Qin Yuan and Zhou Hong stood in the monitoring room together, observing the dynamics of the executive team through remote technical equipment. Qin Yuan's eyes were sharp and his tone was low: "Next, we just need to wait. If someone leaked the information inside, there would be a movement soon."

Sure enough, a few hours later, an abnormal activity occurred in an executive's private email. He sent an encrypted email using his private device, which was the "cooperation plan" mentioned by Zhou Hong at the meeting.

"It's him!" Qin Yuan's eyes sterned, "Immediately locked in his movement trajectory."

Zhou Hong's technical team acted quickly and tracked the recipient of the email as an unfamiliar account. The police further investigated in depth and found that the account was related to the leader of an underground force.

Qin Yuan's eyes were cold and fierce: "Next, we have to let him show up."

Qin Yuan quickly formulated a strict security plan. He stood in Zhou Hong's office, with a calm and decisive tone: "Mr. Zhou, the situation is already very obvious now. You and your family may be the other party's potential targets. From now on, we must do two things: first, ensure your family's safety; second, minimize your chances of being exposed to the outside world as much as possible."

Zhou Hong nodded, with a hint of uneasiness in her expression: "My family has been transferred to my parents' country villa, but that place is not safe. If the other party really has plans, they may have grasped the whereabouts of my family."

Qin Yuan nodded: "You did the right thing and transfer them first. However, this is far from enough. The safety of your family needs professional protection. I have contacted several trusted comrades, who are veterans, have rich experience and can provide 24/7 personal protection."

Zhou Hong breathed a sigh of relief: "That's great, I have always been worried about my parents' safety. If there is a professional protection, I will feel relieved."

"In addition, I need you to reduce the public itinerary immediately." Qin Yuan's voice showed unquestionable majesty. "If you can promote recent meetings and activities, you must report necessary itineraries in advance and be evaluated by my team and I. You must always keep a low profile and do not give each other any opportunity to take advantage of."

Zhou Hong nodded, but hesitated: "I can reduce the itinerary, but the company still has many important cooperation and meetings. If it is absent, it may cause suspicion and may even affect the company's operations."

Qin Yuan looked at her calmly: "Short-term sacrifice is necessary. If something happens to you, the entire company will be worse. Moreover, such low-key behavior may make the other party more anxious and force them to reveal their flaws."

Zhou Hong pondered for a moment and finally made up her mind: "Okay, I'll listen to you. I will let my assistant handle external affairs, and I will try to minimize the appearance of the situation."

"Very good." Qin Yuan nodded, took out a handwritten list and handed it to Zhou Hong. "Here are some specific precautions, you must strictly implement them. First, try to use the company's exclusive vehicle and do not change the way of travel easily; second, avoid going to fixed restaurants or leisure places and keep the itinerary random; third, no unfamiliar phone calls or emails will be replied to immediately and handed over to me or the police for processing."

Zhou Hong took the list, looked carefully, and looked up and asked, "Instructor Qin, do these measures mean that my situation is more dangerous than I thought?"

Qin Yuan's eyes narrowed slightly and he said in a deep voice: "Since the other party has begun to use more extreme means, it means that they are determined to win the core assets of your company. You must be mentally prepared, and this may last for a while until we completely find the mastermind behind the scenes."

Zhou Hong nodded, a trace of determination flashed in her eyes: "Okay, I understand. During this period, I will fully cooperate with your arrangements."

That night, Qin Yuan contacted several retired comrades, who were his partners when performing special missions, and were experienced and loyal.

"Li Rui, you and Liu Jianhua are responsible for the security of Zhou Hong's family." Qin Yuan assigned a task on the phone, "Her family is in a country villa, and it is currently the most susceptible target. I want you to keep an eye on it 24 hours a day and don't let any suspicious characters go."

Li Rui on the other end of the phone chuckled in a low voice: "Don't worry, Lao Qin, we have been brothers for so many years, so I'm not interested in protecting a few people."

"Don't take it lightly." Qin Yuan said in a serious tone. "The other party is likely to be a professional criminal gang, and their methods will not be simple. In this mission, your reaction speed and judgment are the key."

"I understand." Li Rui's voice became serious, "Let's go immediately."

After hanging up the phone, Qin Yuan turned to Zhou Hong and said, "Your family will have two professional security personnel to protect you. I will contact them regularly to ensure everything is normal. I will be responsible for yourselves."

Zhou Hong was a little surprised: "You are responsible for it yourself? Will this delay your other work?"

Qin Yuan sneered, with a hint of sharpness in his eyes: "My job now is to ensure your safety. Don't worry, I won't let you get into trouble."

Zhou Hong looked at Qin Yuan's cold but reassuring face and felt a little comfort in her heart: "Instructor Qin, thank you really. If it weren't for you, I really didn't know how to deal with these things."

Qin Yuan waved his hand: "The responsibility lies. Don't worry, the situation has begun to become clear. Next, what we have to do is wait for them to reveal their flaws."

Qin Yuan called the local police's criminal investigation team leader, and Li Cheng's voice came from the other end of the phone. He was the head of the Tianhui City Criminal Police Team, and his voice was low and capable: "Instructor Qin, are you talking about Zhou Hong's case? We have indeed received some alarm records from her company, but there is currently no sufficient evidence to lock the suspect."

"What's the specific situation?" Qin Yuan frowned slightly, his voice calm but full of oppression, "Do you have any clues?"

Li Cheng paused and explained: "The several intimidation and sabotage cases we have investigated have found that the behavior patterns are very similar, and there may be a group of professional criminals behind them. They poured paint in the parking lot of Zhouhong Company, sent anonymous threatening emails, and also destroyed the security monitoring equipment near her home."
