Sheriff Uncle, open the door quickly! I've come to solve a case!

This startled Feng Yuan so much that she almost fainted.

The husband, Ma Teng, quickly said, "No, don't get agitated. We haven't done anything wrong. Um, child, can you rest in peace? Your husband and I will burn lots of paper money for you."

Fearing the body might suddenly harm the couple, the local police immediately drew their guns and aimed them at Xu Chengxuan, ready to shoot at any dangerous movement he made.

Xu Chengxuan's fingers twitched, and he slowly and weakly began to move, pushing his limp body to stand up straight.

The policeman tightened his grip, about to pull the trigger.

"Don't hurt my brother!" Bai Zhizhi ran into the living room and spread her arms to block Xu Chengxuan.

Then she said to Feng Yuan and Ma Teng, "Uncle and Aunt, please don't send my brother away, he'll be sad!"

Then the police officers watched as the newly arrived adults all blocked Xu Chengxuan, seemingly listening to the child.

"Who are you? You can't disturb the scene!"

Qin Qingzhou took out his identification, and the police officer took a closer look and realized that he was actually a police officer from City A who had come to provide support.

"Officer Qin, what are you doing?"

"Put the gun away," Qin Qingzhou said in a deep voice.

His main concern was that these people would point guns at Bai Zhizhi, which would frighten her.

However, Bai Zhizhi didn't seem scared at all. Instead, she shouted loudly at the couple, "Uncle and Aunt, my brother has been looking for you for so long. Please don't send him away!"

Have you been looking for us for a long time?

Feng Yuan and Ma Teng exchanged a glance, feeling something was off, but they couldn't quite put their finger on why.

And why would this person want to see them? They don't even know him.

"But we don't know him at all! Why is he looking for us? And he... he's dead now, right? We didn't kill him, did we?" Feng Yuan was so frightened that her words became incoherent.

Ma Teng immediately had an idea: "Could he be looking for the previous resident of this house? I have the contact information for the previous resident. Why don't you take him to find that person?"

"No, that's not it! My brother came to see you!" Bai Zhizhi felt that adults were so stupid; they couldn't recognize her even when she was right in front of them. "You're my brother's mom and dad!"

These words struck them like a bolt from the blue, leaving them both frozen in shock.

Looking at Xu Chengxuan's pale face, Feng Yuan felt he looked increasingly familiar: "Is...is that Xiao Xuan?"

"Xiao Xuan?" Ma Teng was also shocked. He forgot his fear and grabbed his wife's hand, walking towards the corpse.

Fearing for their safety, the police tried to stop them, saying, "It's dangerous, don't come near."

To everyone's surprise, the two were not afraid at all. They pushed the police forward and rushed ahead to see what was going on.

"Xiao Xuan has a birthmark on the back of his head." Feng Yuan went to look at the back of the corpse's head and indeed saw a birthmark on it.

"Xiao Xuan! It's our Xiao Xuan!"

Ma Mingxuan is their child. He went missing when he was very young, and they have been searching for him all these years, but their resources are limited, and they have spent all their money without finding him.

More than ten years have passed in the blink of an eye, and when I saw Ma Mingxuan again, I didn't recognize him at first glance.

Feng Yuan was no longer afraid. She hugged the swaying Ma Mingxuan tightly, crying, "My son! My son, I'm so sorry! How did you become like this!"

Ma Teng was also anxious. Since Bai Zhizhi knew he was their son, she must also know other things.

He suddenly knelt before Bai Zhizhi: "Little immortal! Who turned my Xiaoxuan into this! I want them to pay with their lives!"

Their little Xuan came to them even after he'd become like this; he must have suffered some terrible injustice.

"I can't even recognize my own son, I deserve to die!"

"Uncle and Aunt, don't be sad. Brother won't blame you." Bai Zhizhi quickly grabbed Ma Teng's arm.

"My brother also feels guilty. He scared Mom and Dad. If Mom and Dad are sad, my brother will be even sadder."

As expected, Feng Yuan held Ma Mingxuan and felt him trembling, as if he was enduring something.

"Zhizhi will help brother recover a little bit." Bai Zhizhi pulled Feng Yuan away.

The couple stood obediently by Bai Zhizhi's side, crying as they did so, and no one dared to disturb him.

Bai Zhizhi took out a blank yellow talisman and then borrowed a small knife from them.

Fearing the knife might hurt her, Qin Qingzhou took it first, saying, "Let me help you."

"Uncle helped Zhizhi cut her brother's finger."

Qin Qingzhou did as instructed, making a small incision. A drop of blood dripped from the wound, which Bai Zhizhi quickly caught with a yellow talisman.

This scene looked too much like a ritual. Apart from Qin Qingzhou and Li Ku, who remained relatively calm, everyone else looked incredulous and even doubted their own eyes.

Blood spilled onto the yellow talisman. Bai Zhizhi took the talisman in her hand, and the next second, even though there was no source of fire, the talisman burned on its own until it turned to ashes.

Ma Mingxuan's fingertips trembled slightly.

"Dad... Mom..."

"Xiao Xuan!" The couple burst into tears and rushed over to hug Ma Mingxuan, but when they touched his skin, they cried even louder.

"Why is it still cold? Is our Xiao Xuan still alive?"

"My brother is still dead. Zhizhi can only let him talk to Mom and Dad for the time being. But don't worry, Uncle and Aunt, my brother won't die. Zhizhi will bring him back to life."

The two knelt down with a thud: "Thank you, little deity! We'll do anything to save Xiao Xuan!"

The local police officers were completely shocked, their mouths agape in disbelief the entire time, and they seriously doubted that they would soon be leaving the police force to become Taoist priests.

Ma Mingxuan's body was stiff, and his voice was weak: "How am I supposed to live...?"

"Zhizhi, go and get your brother's heart back, and he can live again."

"Heart? Xiao Xuan, what's wrong with your heart?" The couple immediately jumped up from the ground, insisting on checking his body.

Ma Mingxuan dared not tell, fearing that his parents would be even more upset if they found out.

"Brother, only by telling us can Mom and Dad help you," Bai Zhizhi encouraged him.

Ma Mingxuan finally decided to speak out.

It was all part of the Xu family's plan.

Their biological son had a congenital heart condition since childhood, so they went to buy a child from someone long ago.

Ma Mingxuan was the child who was bought. He was young at the time and didn't understand anything. He thought that the Xu family had rescued him from the bad guys.

So he always obeyed his parents, just to repay their kindness in raising him.

For at least a week, his adoptive parents had been very good to him, never shortchanging him in terms of food and clothing. Even his younger brother, Xu Wang, did not ostracize him. He thought he could become a member of the Xu family.

Until last week, Xu Wang celebrated his eighteenth birthday.

His adoptive parents' true colors were fully revealed.

They forcibly kidnapped Ma Mingxuan and swapped his heart with Xu Wang's.
