A song from Chengdu revived a closed-down pub.

At dinner time, the long table in the Ye family's old house was full of people.

Ye Xuan's seat was the only one that was empty.

Ye Wangcheng frowned: "This kid is getting more and more outrageous. He doesn't even come home on such a good day."

Ye Yao put down her chopsticks and spoke up for him: "He might really have something to do. Someone sent him a letter this afternoon, and he left after reading it."

Ye Yun raised his eyes: "What letter?"

Ye Yao recalled, "It seems to have been sent from Qin Province. His name was written on the envelope. I didn't open it. He read it and put it away without telling me what it contained."

Ye Yun and Ye Yao exchanged a glance.

Su Fan's face flashed through their minds simultaneously.

The two exchanged a glance, then both shook their heads, believing that Su Fan wouldn't be that bored.

Ye Xuan did not return to his own apartment, but went directly to his parents' house.

He found several strands of hair on the dressing table and on his parents' bed.

Some are long, some are short.

The longer one naturally belongs to Zhao Ling, while the shorter one belongs to Ye Wangcheng.

He gathered his hair, wrapped it in a tissue, put it in his inner pocket, and drove out of Kyoto that very night, heading straight for a private hospital in a neighboring city.

He handed over three samples and requested expedited paternity testing.

The doctor glanced at him, asked no further questions, took the sample, and told him to come back in three days to pick up the results.

Ye Xuan did not return to Kyoto, but found a hotel near the hospital to stay in.

He barely slept for those three days.

His heart would pound with fear whenever his phone rang.

He became restless when he heard footsteps in the corridor.

He took out the letter and read it more than a dozen times, engraving every word into his mind.

In her letter, the old nun wrote down in detail the events of the switch that happened years ago.

Date, hospital, the farm where the car accident happened, the child left at the orphanage gate.

Every detail fits perfectly, it doesn't look like it was made of cloth.

He kept telling himself, "It's fake, it must be that Su Fan who did it."

But the string in my heart is stretched tighter and tighter.

On the third day, he received the test report.

The result column had a few lines printed on it, ruling out biological parentage.

He read the report over and over again, his pupils dilated, and his lips trembled as he roared out, "Impossible! Absolutely impossible!"

He kicked away the trash can next to the wall, his chest heaving violently.

But the writing on that piece of paper was clear and distinct, in black and white.

Every word silently exposes the flaws in his life over the past twenty years.

"We can't just sit here and wait to die; we must take the initiative and find the person who sent the letter first."

So he rushed to Qin Province.

He found the nunnery by following the address on the letter.

When Ye Xuan went inside, he saw the little nun drawing water from the well.

"Excuse me, is there a Master here whose surname is Song...?"

The young nun put down the wooden bucket, clasped her hands together, and said, "Are you referring to my master, benefactor? My master passed away a few days ago."

Hearing this, Ye Xuan felt not sadness, but rather a sense of relief.

The young nun continued, "Before my master left, he instructed me to tell anyone who came looking for me: What is yours will come to you; what is not yours, you cannot hold onto. Gathering and parting are beyond our control; gain and loss are predetermined by fate. Do not force things; what you gain is a debt. Do not look back; looking back is all in vain."

Upon hearing this, Ye Xuan frowned, suppressing his anger and refraining from lashing out.

As he left the nunnery, his mind was filled with all sorts of thoughts.

"That old nun said that only those with the surname Su are of the Ye family lineage. I'd like to see if that's really true."

To determine Su Fan's authenticity, all that's needed is to obtain his DNA sample.

Ye Xuan didn't dare to directly contact Su Fan, but he could hire someone else.

He had someone keep an eye on Su Fan for a few days and figured out his routine of going fishing at the reservoir every afternoon.

That afternoon, Su Fan sat by the reservoir fishing, as usual.

Just then, his phone rang.

It was an alarm notification from his home security app.

He opened the surveillance camera and saw a shadowy figure sneaking over the wall, looking around the yard, and then reaching the bedroom window.

Su Fan stared at the screen and muttered to himself, "What era are we living in? People still break into homes?"

Immediately afterward, Su Fan dialed Pan Wengang's number: "Gangzi, come to my house right away, there's a thief."

Upon hearing this, Pan Wengang questioned, "Brother Fan, what thief? What era are we living in? Are there still people breaking and burglarizing homes?"

Su Fan put away his fishing rod: "Stop talking nonsense, hurry up, let's go together."

The two arrived at almost the same time.

Su Fan turned in from the east alley, and Pan Wengang rushed over from the west main road. Just then, he saw a figure wearing a hat and a mask climb over the wall of Su Fan's house.

He stumbled and fell several steps when he landed.

Pan Wengang exclaimed in surprise, "Holy crap, there really is a thief!"

Without saying a word, he rushed forward, tackled the person to the ground, pressed his knee against their back, and started punching them.

He hit and cursed at the same time: "You've got some nerve, kid! Breaking into a house in broad daylight?"

The man screamed in pain as he was beaten, begging for mercy: "Stop hitting me! Stop hitting me! I didn't take anything!"

Su Fan stood to the side, watching Pan Wengang's few punches land with brutal force. He estimated that it was about time before speaking, "Alright, Gangzi, let's ask about the situation first."

Pan Wengang threw another punch before grabbing the man by the collar and pulling him up from the ground.

The man's hat fell off, revealing an ordinary face, about thirty years old, with shifty eyes and a scraped lip.

"Tell me, what are you here to steal?" Su Fan asked.

The man lowered his head and stammered, refusing to speak.

Su Fan pulled out his phone from his pocket and waved it: "If you don't tell me, I'm going to call the police. We just lost 100 grams of gold. What's the price of gold now?"

The man's face changed drastically, and he cried out, "I didn't steal anything! You can't frame me!"

Su Fan laughed: "Whether you've been wronged or not depends on whether you tell the truth or not. Oh, I forgot to tell you, my security camera captured you climbing over the wall to get into the house just now, in high definition."

He opened the surveillance footage on his phone and turned the screen around.

The man stared at his own furtive figure on the screen, his face turning deathly pale, utterly deflated.

"Yes...someone paid me to come. He didn't want anything valuable, he just wanted me to find your hair."

Upon hearing this, Su Fan immediately understood what was going on.

He thought to himself, "It seems the old nun didn't take this to her grave. Taking my hair, she's probably going to do a paternity test to see if it's from the Ye family or Ye Xuan?"

Su Fan remained expressionless and continued, "Who hired you?"

The man shook his head: "I don't know him. He gave me 20,000 yuan in cash and said he wanted me to find a way to get your hair."

Su Fan continued, "Was it a man or a woman who hired you?"

"Male."

Su Fan thought for a moment, then pulled out a video of his confrontation with Ye Xuan from his phone and held the screen up to the person: "Look, is this the person?"

The man squinted for a moment, then nodded repeatedly, "It's him! It's him! It's definitely him!"

Su Fan put his phone away, understanding dawning on him: "Since Ye Xuan personally took action, it means the Ye family doesn't know about this yet, otherwise they wouldn't have sent Ye Xuan to do it. It seems Ye Xuan has come to confirm my identity."
