Solving the case: Combining the police dog's olfactory genes at the beginning

"These are all nonsense."

Luo Fei interrupted him.

"Let me tell you a story. Five hundred years ago, there was a young doctor named Ouyang Xun who was taken in as a disciple by a Taoist priest and learned many Taoist arts. Later, he fell in love with a woman and stole the Taoist temple's magical artifacts to elope down the mountain."

Ouyang Xiu's hands began to tremble slightly.

Luo Fei continued.

"Ouyang Xun became a wealthy merchant through his own efforts, but he fell seriously ill at the age of 50. In order to survive, he used a soul-shifting technique to transfer his soul into his son's body. Every 50 years thereafter, he would use the soul-shifting technique to take over the body of his descendants, a practice that continues to this day."

“You’re that Ouyang Xun.” Luo Fei stared at Ouyang Xiu. “Am I right?”

Ouyang Xiu's expression instantly turned ferocious, but he quickly regained his composure.

"Captain Luo, this is all feudal superstition. This is the new century. Aren't you afraid of damaging your image by arresting people on such grounds?"

Luo Fei smiled calmly.

"I am the head of the Special Cases Unit of the 18th Bureau of the Ministry of State Security, specializing in handling special cases. Don't worry about my image."

Ouyang Xiu threatened.

"You should be aware of the influence the Huaxiong Group wields in Shanghai. I can ruin your future!"

Luo Fei remained unmoved and clapped his hands lightly. Chen Yifan walked in carrying something wrapped in white cloth, placed it on the tea table, and then left.

"Do you know what this is?" Luo Fei lifted the white cloth, revealing a black weight. "This is called the Soul-Locking Weight. It can extract and imprison the soul that has taken over another's body, preventing the evil spirit from ever rising again."

Ouyang Xiu's face turned deathly pale instantly, and he broke out in a cold sweat.

Luo Fei picked up the Soul-Locking Stone and approached step by step.

"Want to try its power?"

Ouyang Xiu retreated in terror, eventually collapsing to his knees.

"Don't come any closer! I admit it! I am Ouyang Xun!"

He crawled to Luo Fei's feet.

"I'll give you money! One billion! No, ten billion! As long as you pretend you don't know anything about this! One billion for each member of your team!"

Luo Fei stared at him coldly.

You think money can solve everything?

Ouyang Xiu hurriedly said.

"I can give you half of Huaxiong Group's shares! Just let me go!"

Luo Fei coldly stared at Ouyang Xiu, who was kneeling and begging for mercy.

"I'm not interested in money."

Ouyang Xiu hurriedly said.

"Captain Luo, Huaxiong Group has more than a dozen branches, four or five of which are already listed on the stock exchange. We pay tens of billions of yuan in taxes every year and provide economic support to hundreds of thousands of families. If something happens to me, the company will go bankrupt, and countless families will be plunged into hardship!"

He continued to plead.

"If you let me go, I will immediately establish a charitable foundation with an initial investment of 100 billion! From now on, I will dedicate half of the group's net profit to charity every year!"

Luo Fei remained silent for a moment. He did need to weigh the pros and cons: arresting Ouyang Xun might lead to economic turmoil, but letting him go might cause more people to suffer.

Ultimately, Luo Fei made his decision.

“I can let you go, but I must send someone to Huaxiong Group to supervise you. You must promise not to possess anyone again and spend the rest of your life making amends for your mistakes.”

Ouyang Xiu nodded repeatedly.

"I promise! I promise everything!"

Back in command center, Luo Fei announced the decision. The team members were all surprised.

"Let him go?" Chen Xuanran asked incredulously.

Luo Fei explained.

“He promised to establish a 100 billion charitable fund and donate half of the profits every year. We will send people to supervise him to ensure that he does no more evil.”

Wang Feifei frowned.

"But."

Luo Fei interrupted him.

"Another announcement: I have been appointed as the director of the 18th Bureau of the Ministry of State Security."

Everyone looked at him in surprise.

“I will temporarily serve as the head of the special case team,” Luo Fei continued. “Yifan will serve as the deputy head. Once you have matured, the head position will be handed over to you.”

Chen Yifan said excitedly.

"Thank you for your trust, Director Luo!"

Luo Fei emphasized.

"Although we will let Ouyang Xiu go, we will set up a surveillance team to be stationed in Huaxiong Group to ensure that he keeps his promise."

On the third day, Luo Fei traveled to Kyoto to report to Lei Wanting. On the plane, he repeatedly pondered the details of the case, when suddenly his expression changed.

"No! I've been tricked!"

He suddenly realized: the one who possessed Ouyang Xiu's body was not Ouyang Xun, but Zhu Xuanyang! Zhu Xuanyang had known about Ouyang Xun's plan all along and was using Luo Fei to achieve his own goals!

Since phone calls weren't allowed on the plane, Luo Fei could only anxiously wait for landing. As soon as the plane touched down, he immediately contacted his team in Shanghai.

"Xiao Bei! Where is Ouyang Xiu?" Luo Fei asked anxiously.

Zhou Xiaobei answered.

“I was monitoring him from outside his office while he was working inside.”

Luo Fei was greatly surprised.

"Go in and check immediately! Quickly!"

The sound of a door opening came from the other end of the phone, followed by Zhou Xiaobei's exclamation, and then the call was cut off.

"Xiao Bei! Xiao Bei!" Luo Fei shouted into the phone, but there was no response.

He immediately contacted Chen Yifan.

"Yifan! Take some men to Ouyang Xiu's office! Something might have happened to Xiao Bei!"

Chen Yifan asked in shock.

"what happened?"

Luo Fei quickly explained.

"We've been tricked! It was Zhu Xuanyang who possessed Ouyang Xiu! Act now! I'm heading back to Shanghai immediately!"

After hanging up the phone, Luo Fei immediately changed his flight to the earliest one back to Shanghai. While waiting for his flight, he repeatedly tried to contact Zhou Xiaobei, but received no response.

On the plane, Luo Fei was extremely anxious. He recalled all the details: Zhu Xuanyang's sudden death, Ouyang Xiu's abnormal behavior, and that Soul-Locking Pill—it was all part of Zhu Xuanyang's plan!
Two hours later, the plane landed at Shanghai Airport. Luo Fei immediately received a message from Chen Yifan upon turning on his phone.

"Director Luo, Xiao Bei is seriously injured and unconscious, and Ouyang Xiu is missing. We are conducting a full-scale manhunt."

Upon returning to Shanghai, Luo Fei rushed to the hospital to visit Zhou Xiaobei. Although he had suffered a head injury, Zhou Xiaobei had regained consciousness and his injuries were not serious.

"Captain Luo, I'm fine." Zhou Xiaobei struggled to sit up. "That Ouyang Xiu... he's acting strangely."

Luo Fei held him down.

“I know. It wasn’t Ouyang Xun who possessed Ouyang Xiu, but Zhu Xuanyang.”

Chen Xuanran asked in surprise.

"How are you sure?"

Luo Fei explained.

"Do you remember Zhu Xuanyang saying he liked coffee? But both Ouyang Xiu and Ouyang Zhenghua are allergic to coffee. Yet at Huaxiong Group, I saw a cup of coffee in front of Ouyang Xiu."

He continued.

"Furthermore, Huaxiong Group gave Pan Meilian ten million in compensation. This is highly unusual, unless Zhu Xuanyang is repaying a debt of gratitude—after all, Pan Meilian served him for more than a month."

Wang Feifei suddenly realized.

"So Zhu Xuanyang faked his death to escape, but actually succeeded in possessing Ouyang Xiu's body!"

Luo Fei nodded.

"As a Taoist master, Zhu Xuanyang's pursuit of immortality far surpasses his desire for wealth. He would rather give up the Huaxiong Group's hundreds of billions of assets in order to obtain a new body."

Chen Yifan said with concern.

“If he finds an accomplice and transfers his soul again, it will be even harder for us to track him down.”

Just then, Zhou Xiaobei reported.

"Captain Luo, the surveillance footage shows that after Ouyang Xiu left Huaxiong Group, he took a private jet to Jiangcheng!" Luo Fei immediately gave the order.

"Attention all personnel! Proceed to Jiangcheng immediately!"

On the private plane bound for Jiangcheng, Luo Fei assigned tasks.

"Xiao Bei, monitor all of Ouyang Xiu's accounts. Fei Fei, Pei Xiong, you two go and stake out Zhu Xuanyang's residence in Jiangcheng. Yi Fan, contact the Municipal Criminal Investigation Team for cooperation. Xuan Ran, Bing Yan, and Mu Chen are in charge of logistical support."

Upon arrival in Jiangcheng, the city's criminal investigation team responded swiftly. An arrest warrant was issued throughout the city, and thousands of police officers sealed off all entrances and exits to Jiangcheng, imposing a citywide curfew.

Luo Fei's goal was clear: to trap Zhu Xuanyang in Jiangcheng and prevent him from possessing another body.

Three days have passed, but Zhu Xuanyang has vanished without a trace, as if he had evaporated into thin air.

The atmosphere in the command center was heavy. Zhou Xiaobei reported.

"There are no hotel check-in records, no electronic payment records, and no surveillance footage captured his whereabouts."

Wang Feifei and Wu Peixiong staked out Zhu Xuanyang's residence but found nothing.

Chen Yifan frowned.

“All entrances and exits to Jiangcheng are blocked; there’s no way he can escape.”

Yuan Bingyan proposed it.

"Could he have already possessed someone else?"

Luo Fei shook his head.

"The Soul-Stealing Technique requires specific conditions and time. He should still be in Jiangcheng, hiding somewhere we can't imagine."

Su Muchen suggested.

Should we expand the search area?

Luo Fei pondered for a moment.

"No, he must be in Jiangcheng. We just haven't found the right direction to search yet."

Chen Xuanran suddenly said.

"Do you remember Pan Meilian? Does Zhu Xuanyang have other lovers in Jiangcheng?"

Luo Fei's eyes lit up.

"Good idea! Xiao Bei, investigate Zhu Xuanyang's social connections in Jiangcheng!"

Zhou Xiaobei quickly searched.

"Zhu Xuanyang has a female disciple in Jiangcheng named Lin Xue, who is the owner of a yoga studio."

Luo Fei immediately gave the order.

"Yifan, take some men to the yoga studio! Feifei, Peixiong, you two continue to keep watch on Zhu Xuanyang's residence. The rest of you, split up and search places he might be hiding!"

Chen Yifan led his men to the yoga studio, only to find it closed. A neighbor said Lin Xue had gone on vacation three days prior.

“It’s been three days again,” Chen Yifan frowned. “The timing is too coincidental.”

Meanwhile, Wang Feifei and Wu Peixiong spotted a suspicious person while staking out Zhu Xuanyang's residence.

"Team Leader Luo, there's a man wearing a mask loitering around here, behaving suspiciously," Wang Feifei reported.

Luo Fei gave the instructions.

"Follow them quietly, without alerting them."

The man wandered around the alley a few times before suddenly disappearing through the back door of a teahouse.

Wu Peixiong said in a low voice.

"The owner of this teahouse is a distant relative of Zhu Xuanyang."

Luo Fei immediately gave the order.

"Seal off the teahouse! Prepare for a surprise inspection!"

The special task force members quickly surrounded the teahouse. Luo Fei led the charge inside, only to find the teahouse empty, with only a faint scent of sandalwood wafting from the backyard.

"There's a secret room!" Chen Xuanran discovered a hidden door.

Behind the hidden door was a staircase leading underground. The group carefully descended and discovered a secret room set up as a dojo.

Candles were lit in the secret room, the walls were covered with talismans, and an altar stood in the center. On the altar were some ritual implements and an ancient book.

Zhou Xiaobei examines ancient books.

"It's the secret manual of the Soul Transference Technique! Zhu Xuanyang is indeed here, preparing to cast the spell again!"

But the secret room was empty. Luo Fei frowned.

"He left not long ago. The candle is still burning, which means he will come back."

Wang Feifei asked.

"Should we keep watch here?"

Luo Fei shook his head.

"He's too cunning; he won't come back easily. We need to think of another way."

Back in the command center, Luo Fei re-examined the clues. Suddenly, something occurred to him.

"Xiao Bei, check all the Taoist temples and Buddhist monasteries in Jiangcheng! Zhu Xuanyang might need a place with abundant spiritual energy to perform his spells!"

Zhou Xiaobei quickly searched.

"Jiangcheng has twenty-three Taoist temples and thirty-six Buddhist temples."

Luo Fei gave the order.

"Separate teams to search! Focus on remote Taoist temples that are not popular with worshippers!"

As night fell, members of the special task force dispersed to search various parts of Jiangcheng. Luo Fei and Chen Xuanran arrived at a dilapidated Taoist temple in the suburbs.

The Taoist temple was quiet, with only an old Taoist priest meditating.

Luo Fei presented his identification.

"Master, have you seen this person recently?" He took out a photo of Ouyang Xiu.

The old Taoist priest squinted for a while, then shook his head.

"never seen it."

Chen Xuanran suddenly noticed that the offerings on the altar looked very fresh, as if they had just been placed there.

"Taoist Master, do you need so many offerings for yourself?" Chen Xuanran asked.

The old Taoist priest's expression changed slightly.

"Well, it's always good to be prepared."

Luo Fei noticed something was wrong and secretly sent a message to Chen Yifan.

“We brought people to Qingxu Temple in the suburbs, and they made a discovery.”

Just then, a slight noise came from the backyard. Luo Fei and Chen Xuanran immediately rushed over and saw a dark figure quickly scaling the wall and escaping.

"Chase!" Luo Fei shouted.

But the shadowy figure had already vanished into the night. Chen Xuanran found a Taoist robe in the corner, from which a cell phone had fallen out.

Zhou Xiaobei remotely unlocked the phone and quickly made a discovery.

"Captain Luo! There's an unsent message on your phone: 'Tomorrow at midnight, Qinglong Mountain!'"

Luo Fei's eyes sharpened.

"He's going to perform a spell at Qinglong Mountain tomorrow! Everyone, take note! Proceed to Qinglong Mountain immediately to set up surveillance!"

When news of Ouyang Xiu's wanted status reached Shanghai, the Ouyang family was thrown into chaos. The local police informed the family that Ouyang Xiu was a wanted criminal by the National Security Bureau, and that he was connected to the deaths in the Firefly Forest.

With the chairmanship of Huaxiong Group vacant, the stock price plummeted, resulting in a market value loss exceeding 10 billion. Ouyang Xiu's siblings began vying for control, throwing the company into chaos.

Luo Fei was extremely anxious after receiving no news from Ouyang Xiu for several days. He personally checked Zhu Xuanyang's residence in Jiangcheng and found that he had not returned home, had not checked into a hotel, and had not used electronic payment.

“Someone must be helping him,” Luo Fei told the special case team members. “Zhu Xuanyang definitely has accomplices in Jiangcheng.”

Just then, Chen Yifan made an urgent call.

"Captain Luo! We found Ouyang Xiu! In Lao Jun Cave, Nanshan, Jiangcheng City! But he's dead!"

Luo Fei immediately led his team to Lao Jun Cave in Nanshan. The scene had already been cordoned off by the local police, and two bodies lay in the center of the altar—Ouyang Xiu and a Taoist priest.

"The deceased was Zhu Xuanyang's apprentice," the forensic doctor at the scene explained. "The time of death was approximately midnight last night. Both died from cardiac arrest, and there were no external injuries."

Luo Fei carefully observed the scene. The altar was set up strangely, with candles lit around it, strange talismans drawn on the walls, and various ritual implements placed in the center.

"Another soul-shifting technique," Luo Fei frowned. "Zhu Xuanyang must have performed some kind of ritual here." (End of Chapter)
