It was late at night, and in the West Lane of Chang'an, a simple house was still lit up.

A sixteen-year-old boy dressed in gray cloth sat cross-legged at a wooden table with a sheet of paper copied with poems. The tip of the young man's pen lightly dipped the inkstone, glanced at the books on the table, and wrote: Ten years of night rain in the rivers and lakes.

On a chair in front of the wooden table sat a gray-haired old man, holding a book and a blue robe, flipping through the undimmable oil lamp. If you look closely, the old man's left eye has long been blind, and his right eye is still clear and clear.

In this small house, the most piled up are books. In addition, there are two xylophones, a game of chess, and dozens of paintings.

"Crunch ......"

The door panel was gently pushed open, and a strong wind blew the paper off the wooden table.

The young man and the old man turned their heads to look at the door, only to see a soaking wet man walking in. His eyes widened, and he looked at the old man with a respectful expression.

The rain dripped down his face, leaving him with several new wounds, blood spilling from his breaths in a terrifying way.

He didn't blink his eyelids, and struggled to spit out three words:

"Ten Years of Lighting ......"

The man spoke, flicking his fingertips, and a cyan object shot at the old man.

The man then glanced at the young man at the wooden table with a deep gaze, then closed his eyes and fell to the ground with a bang.

The young man's figure was stunned suddenly, and he quickly stood up, his eyes showing panic and anger.

"Whoosh!"

Immediately afterward, three figures rushed into the room like a swift wind, and one of them held a token and shouted at the two of them: "The Heavenly Supervisor handles the case!"

After speaking, the other two figures immediately walked into the house and searched carefully. He also turned and crouched, carefully examining the man who had fallen to the ground.

The young man and the old man watched the scene in front of them motionlessly, allowing the two to rummage and search the room.

After a while, another person came outside the house, he took off his hat, revealing his vicissitudes of life, and his eyes stared at the old man and the young man like a sharp sword.

His expression changed from fierce to solemn, and then showed a look of surprise, but soon changed to the same sharp face as before.

He forcibly suppressed the fluctuations in his heart, and said hurriedly: "Mr. Qin, I didn't expect to meet you in Chang'an!"

"Mr. Qin, ancestral home in Yangzhou, at the beginning of the imperial examination in the prosperous Taiguan Dynasty as an official, Taiguan 11 years as the director of the Guozijian business, Taiguan 16 years because of the left eye was blinded resigned and returned to his hometown, in Yangzhou City a small courtyard to teach. Taiguan left Yangzhou in the eighteenth year, and there has been no trace since then. ”

Only then did the two discover that behind the man in the cloth, there was also an official who was holding a book and read it in a deep voice.

"Your Heavenly Supervisor's intelligence skills are still so meticulous. The old man sighed in a hoarse voice.

Mr. Qin smiled. The man in the cloth shook his head and said, "Since you have been out of the sight of the Heavenly Supervisor, why do you want to return to Chang'an?"

The Prison Division, the largest intelligence department of the Shengshi Dynasty. Countless people have spent their lives trying to escape from their sight, but in the end, even the location of the grave is clearly recorded in the scriptures.

"When people get old, they always miss the trivial things of the past, so they just come back and take a look. The old man said helplessly.

The man in the cloth stared at the old man for a long time without changing his face, and then shifted his gaze to the young man on the side. Perhaps numb from fright, the young man's figure did not move.

"Who is he?"

"My closed disciple, Xu Changfeng. The old man explained unhurriedly, "He has been studying with me for many years, and he also wants to come to Chang'an to have a look." ”

"Xu Changfeng, who is your father's name, where does your family live?" so the man stared at the cloth-clothed young man and asked.

"My father and mother died early, and when I was six years old, I came to Yangzhou to beg, and Mr. Qin saw that I was pitiful, so he accepted me as a disciple and took me to travel to the Quartet ...... education."

Xu Changfeng's voice was very small, and he trembled slightly.

As he spoke, the two people who were searching the house returned to the man in the robe, and the official who was squatting on the ground stood up and whispered, "Your Excellency......"

When the man in the cloth heard this, he immediately waved his hand to stop it.

"Yes!"

The officer nodded, and then, along with the other two, lifted the man up and left the house in the pouring rain. A clear trail of blood was left on the ground.

The man in the cloak and the official behind him who was holding the tome still stood.

"Do you recognize the man who just died?" asked the man in the robe.

Xu Changfeng shook his head, his face numb.

Observing words and expressions is just the basic skill of an official of the Heavenly Supervision Division, and just by a person's words and deeds, and facial expression, one can know seven points of what is in his heart.

The man in the cloth immediately faced the old man and said, "He is Zhao Xinji, a serious offender in the prison, Mr. Qin won't say that he doesn't know, right?"

"I've heard a little. The old man nodded.

"He escaped from prison on a rainy night and escaped from me, why did he come to you?" asked the man in the robe.

The old man shook his head, but did not speak.

"Didn't he say something when he came here?" said the man in the robe, with a slight impatience on his face.

"At that time, Xu Changfeng and I were reading and writing in the house, and he suddenly broke down the door, covered in blood. Before he could speak, he fell to the ground and did not wake up. After that, the men of your heavenly superintendent arrived. ”

The old man spoke very plainly, as if he had forgotten the scene just now.

"Boom!"

Outside the house, there was another flash of lightning, and the thunder shook the oil lamp and kept flickering, and the room was bright and dark.

The man's gaze kept wandering back and forth between the old man and the young man, as if he wanted to see something.

"Whoosh!"

Immediately afterwards, another official came in the rain and said respectfully in the rain:

"Supervisor Mo, the prince ordered you to enter the palace immediately. ”

"Got it. The man in the cloak replied in a low voice, and once again glanced at the piano, chess, calligraphy and paintings in the room, wondering what he was thinking.

"Don't stop the wind and take the liberty of bothering, take your leave!"

The man in the cloak bowed to the old man, turned around and closed the door and left.

Xu Changfeng and Mr. Qin quietly looked at the closed door, the rain was loud and loud, and the blood stains on the ground were still clear and visible.

After a long time, Xu Changfeng was sure that the people of the Heavenly Prison Division had left, and the sluggish expression on his face dissipated, and he frowned slightly and turned to look at Mr. Qin and said:

"Mr. Qin......"

"This matter is over!" Mr. Qin showed a serious look on his face, "You go back to your room to rest, and you don't have to get up early tomorrow to read in the morning." ”

Xu Changfeng nodded and walked quickly into the room on the right.

At this time, Mr. Qin was the only one left in the room, staring at the blood on the ground with his eyes and sighing long.

With a slight movement of his thumb, he pulled a cyan thread from between his fingernails.

The thing that Zhao Xinji sent out just now is this green silk.

Mr. Qin stretched the green silk, and saw that this foot-long green silk was densely knotted.

The knot code, the things that Zhao Xinji wants to tell him, are all on this green silk.
