The Last Mr. Dongguo

The recording was incomplete, seemingly due to sudden sabotage. Bai Xin listened to it several times before extracting the name "Chen Huan" and handing it to Dongfang Lin for investigation. Soon, information on all people named Chen Huan in Huzhe City appeared on Dongfang Lin's computer. After cross-checking, they finally identified Chen Huan as the vice president of He Huan Company and Gu Hezhi's prized student.

"Team Leader Bai, this should be the person. He's not only connected to Gu Hezhi, but He Huan's company was originally He Chuan's company." Dongfang Lin pulled up all of Chen Huan's information.

"Hmm, it seems we should start our investigation with Chen Huan. Also, take this recording back and do a detailed analysis."

"Understood. Haha, Captain Bai," Dongfang Lin grinned mischievously, "Since you're here, senior brother, I'll leave psychology to you. Senior brother, here comes your forte."

At this moment, Huan Yijun did not react to Dongfang Lin's words. He stared intently at the distance, fully alert, and moved slowly. Bai Xin also noticed the abnormality, drew his sidearm, cocked it, and followed behind Huan Yijun.

Suddenly, a figure darted out from afar, turned around quickly, and ran towards the exit.

"stop!"

Huan Yijun also suddenly quickened his pace. The sudden burst of power allowed this seemingly weak man to display extraordinary agility.

"Seal off all exits and strictly prohibit all personnel from entering or leaving."

Bai Xin followed closely behind Huan Yijun, the two locked in a fierce battle.

Suddenly, a beam of light shone from a vehicle at the exit, obstructing Bai Xin and his companion's vision. By the time their vision returned, the other party had vanished.

"What's wrong with you?" Bai Xin pounded on the hood of the car, which was emitting high beams. "Get out, get out!"

The driver, who had turned on his lights, got out of the car trembling, speaking incoherently and stammering.

"I...I...I just...I was just...driving...a car, this...this..."

"Alright, alright, they've already run away." Huan Yijun sighed repeatedly, but it was too late. "Go over there and register, and remember to use your high beams less when you drive in the future. Let's go."

"I...I understand." The driver staggered and almost tumbled as he pulled out his ID card and handed it to Dongfang Lin.

In the dense forest, King of Hearts, a cigarette dangling from his lips, observed his surroundings. A figure gradually came into focus around the corner.

"You've been exposed. It's best not to take any further action for the next few days."

"Exposed? How could that be?"

"Liu Wei installed a bugging device in his home, connected to his car. You were so careless; you didn't even see through this little trick?"

"Bug listening devices? I checked everything when I got to his house, and there was nothing unusual."

"In short, it's no use talking about this now. Fortunately, the recording is only half complete and doesn't contain much information. It only mentions Gu Hezhi, Chen Huan, and Fei Li, among others."

"Could it be that ashtray?"

"That's all unimportant now. Bai Xin has already begun investigating Chen Huan, and your whereabouts could be tracked at any time. You must be extremely careful in the future and make sure you don't make the same mistake again."

"Understood, I understand."

The enormous crystal chandelier and the opulent European-style decor made Bai Xin and Huan Yijun feel as if they had stepped into the lobby of a high-end hotel. Chen Huan, wearing pajamas, smiled as she descended from the second floor, waving to signal the nanny to leave.

"Hello, I'm so sorry, I get sleep-deprived when I'm busy. I just woke up because of work, please don't mind. Please have a seat."

Huan Yijun easily noticed Chen Huan's deliberately casual attire and his attempts to conceal his nervousness.

After some pleasantries, the conversation got straight to the point. Bai Xin tentatively asked, "I heard you're a student of Professor Gu Hezhi at Huze University. What are your thoughts on Professor Gu's disappearance?"

"Professor Gu has disappeared? No way! I was having tea with him just two days ago." Chen Huan feigned surprise, her gaze shifting between Huan Yijun and Bai Xin.

"Two days ago, exactly what date?"

"August 14th, that's the day before yesterday. He's my teacher; we often have tea and meals together." Chen Huan didn't understand what Bai Xin's question meant; fear and worry were evident on his face. His intuition told him that the police visit wasn't so simple. "Are you sure Professor Gu is missing?"

"It's basically confirmed that Professor Gu's disappearance is related to his research findings. Could you tell us what research topic Professor Gu has been working on recently? Also, we'd like to learn more about Professor Gu's daily life. You and Professor Gu are both teacher and friend, so you should be quite familiar with him. That's why we're here to see you. We hope you'll cooperate actively and help us find Professor Gu as soon as possible." Huan Yijun spoke slowly and calmly, as if talking to a patient. This eased the other party's wariness while quickly getting to the point.

"Oh, no problem, I'll definitely cooperate." Hearing Huan Yijun's words, Chen Huan also showed worry and unease. While pretending to try hard to remember, he said, "I've been busy with the company lately, so I haven't been able to go to the school as often. However, Professor Gu has devoted his entire life to scientific research, and his research topic has always been the same: to discuss the intrinsic relationship between the Classic of Mountains and Seas and Baizhugou, as well as the effects of its unique internal properties on the human body."

Chen Huan, seeing Bai Xin's puzzled expression, explained, "Simply put, the teacher believes there's a connection between the *Classic of Mountains and Seas* and Baizhugou. Baizhugou is located at 30° North latitude, and as you know, 30° North latitude is a mysterious place. Besides the unusual activity of the Earth's crust, what's even more mysterious is that this latitude line passes through the locations of many famous and perplexing natural and cultural mysteries around the world. For example, the ancient Egyptian pyramids, built precisely at the center of the Earth's landmass; the enigmatic Sphinx; the legendary site of the sunken Atlantis; the terrifying Bermuda Triangle; and the ancient Mayan civilization ruins that have amazed humanity for centuries. This area is also called the 'Mysterious Vortex Zone,' and countless planes and ships have disappeared here over the years."

"But these are all just legends."

"Haha, Captain Bai, the words of ignorant people may be legends, but the conclusions drawn in this technologically advanced era are no longer legends. The most obvious thing now is that the 30° North latitude region is filled with strange magnetic fields, and Professor Gu wants to study the special properties of these magnetic fields so that he can apply them to technology to improve people's lives. In the process of research, Professor Gu searched through ancient books and documents and made a great breakthrough in the Classic of Mountains and Seas."

"What breakthrough?"

"Because the research hasn't been made public yet, I don't know much, just the general outline. All the firsthand information is with Professor Gu." Chen Huan gave an awkward smile, his eyes filled with regret and dissatisfaction. "Research findings are like your criminal records; not just anyone can see them."

"So what did you do all day yesterday?"

Huan Yijun's sudden change of topic caused a brief change in Chen Huan's expression.

"What? You doubt me?"
