In the quiet night, in the city of Nanxi County, where there was a curfew, the wind was blowing.

Ping Gaoyi was dressed in a night suit and tiptoed above the roof.

The swallow three times copied the water, and the whole person seemed to melt into the night, riding the night breeze, without a sound.

As the top wind medium of Lingling Water Pavilion, Ping Gaoyi's light skills are naturally not to be said.

After separating from Fang Tai during the day, he walked around the city, and after figuring out the arrangement, he found a secret way to spread the news that the two had arrived. According to the experience in the past, it would take about six or seven days to receive a reply from the Xue Pavilion Master.

But in the days of waiting, since Fang Tai had already taken the initiative to join the Rejuvenation Medical Center to investigate Tai Feng's news, the rest of the matter was the mystery of Cheng Feng's death.

According to the information heard by the detectives, Cheng Feng's body has been examined and has been collected in Yizhuang. Over there, he had already slipped in and looked through the autopsy records - the sharp blade cut the stomach and intestines to death. Such a reason refers to the statement of the post soldier who spread the news earlier, and the two phases also correspond.

Now that the cause of death has been determined, in this case, there are only two main points in this case: the murderer's motive for killing and whether Cheng Feng is a spy or not.

According to the records in the cabinet, Cheng Feng's identity is a soldier who was discharged from the army due to injury, and once served as a personal soldier under General Feng Changqing, and later returned to Nanxi County to live, and gradually became a post officer.

As a member of the Lingling Water Pavilion news network, it was three years after he returned to Nanxi County.

At that time, General Feng Changqing had not yet died, and under his instructions, the army sent people to take the initiative to find the Lingling Water Pavilion and explained the reason to the old pavilion master.

They want to use the wind media to build a more independent, more secretive, and more efficient messaging channel.

As for the reason, General Feng only said one word - inner ghost.

He suspected that there were spies in the army and even in the imperial court who were bribed or even sent by Tibet, secretly disturbing the accuracy and timeliness of information transmission.

Therefore, at the suggestion of his subordinates, he simply broke away from the conventional channels and used the people in the rivers and lakes in the grassy green forest to start a new stove to completely avoid possible internal constraints.

So the old pavilion lord readily agreed, and ordered the cabinet to carefully screen honest and reliable people, and secretly instructed the opportune time, without disclosing it to everyone in the pavilion, and really built this more secret network attached to the original message transmission channel of the Lingling Water Pavilion!

But after all, wind media are not professional spies, they are better at inquiring and disseminating, rather than infiltrating enemy camps and enemies to make false promises. Therefore, in order to increase the reliability and confidentiality of the information, General Feng activated a group of veterans who had been disarmed and returned to the field, as well as secret agents who were already undercover in the enemy, so that they could connect with the newly established secret network.

In the final analysis, the wind media is just a means used by the Lingling Water Pavilion to make money and make a living, and after cooperating with the army, the cabinet has a stable source of money, and General Feng has a better channel for messaging.

Win-win.

It was at that time that Cheng Feng joined the Lingling Water Pavilion.

This is also the main reason why Ping Gaoyi ruled out his identity as a spy after thinking about it for a while.

They have all fought with Tubo on the battlefield, will they still be bought?

Therefore, why the murderer identified him as a Tibetan spy and killed people is what Ling Ping Gaoyi is most puzzled about.

Now that the body has gone to Yizhuang, there is no value to be examined, so all that remains is the scene of the murder - Nanxi County Post Station!

So, after Ping Gaoyi came out of the place, he went straight to the east of the city.

At this time, the post station had been blocked by the soldiers of the yamen, and even the post soldiers who ensured safety on weekdays and the post households who were responsible for chores were not allowed to enter or leave, leaving only a master from the county government to sort out official documents and private messages.

A seal was affixed to the door of the deceased's original residence, and the contents were not touched after the body was taken away.

Wu Huizhou personally explained these things, and he also said that he planned to come back tomorrow to check carefully to see if there were any missing clues.

Since it was said by the county lord, the people under his command would not touch this mold. Not to mention that everyone knows that although the biggest power in the county is in the hands of Lord Xie, the county officials might as well be in charge now!

Everyone is convinced of Wu Xiancheng's methods, not to mention that the soldiers' salaries have to be distributed from him.

The six Liu Daozi who guarded the post station also understood this truth, and as soon as they closed the doors and windows everywhere, they divided into two groups before and after the post station.

"Brother Dao, do you say that Lao Cheng, this old thing, is really that bold?"

"Bi Niang, how can I know!"

"Did you see that earlier? That knife pierced the back! What a ruthless hand! ”

Another big-headed soldier answered, "Not really! We haven't died in Nanxi for many years, and this one is a big one! ”

"And the bloody words on the wall, Tubo treachery! What do you think we have in Nanxi to worry about......"

"Maybe you fell in love with the lady in the building? It's better than the white ...... over there."

"Bi Niang, Lao Tzu let you guess! Guess! Guess! ”

Wu Changliu Daozi listened to the nonsense of the two subordinates, so he couldn't help but get angry, and stretched out his hand to give a few heavy bursts.

"Bi Niang, I don't know how big this is, right? Return his mother's nonsense! Put the tricks on Lao Tzu, if Lord Wu comes to check the post, look at your hangerlangdang, sooner or later we will be cured! ”

"Brother Dao, don't fight, don't fight! Don't think too much, since this murderer has finished killing people, what is he doing when he comes back? Where people have died, others don't want to get closer. Don't worry, no one will come at night! ”

"That's it! How cold it is on this big night, who has nothing to do to stay here...... Alas, what do you have in your arms? Give you a sip of warmth and warmth! ”

"Bi Niang, when did you hide it? Kid chicken thief! ”

"Hey, hey, hey! I know Brother Dao, hello this. It's not that I know that my brother has this errand a few nights, so the little one asked someone to secretly send a pot over. That's right, Brother Dao, you take a bite first! ”

"Tsk! Damn it, you kid has a lot of eyes. It's a pity......"

"Eh, don't worry, Brother Dao, what do you think this is?"

"Bi Niang's, the braised chicken in Lao Qian's house! I said how I always smell a different smell! Bah! You haven't washed it for a few days, and your body stinks, how can you eat this chicken! ”

"Isn't this wrapped in several layers of oiled paper...... I'm afraid that Lord Wu will see it, and I won't dare to take it out until they are all gone, and Brother Dao will ...... it."

Several people shouted and gathered together to divide the wine and meat, which provoked another group of soldiers who were on the night watch to hear it, and immediately felt as if there were gluttonous worms crawling around in their stomachs.

However, the family is the captain of the army, so naturally there are subordinates who worship him.

A few of their big-headed soldiers, you look at me, I look at you, each sighed, and had to continue to move their hands and feet to dispel the coolness of this early spring night.

A gentle breeze blew, and there were a few chirps of owls and the sound of tree branches touching in the night sky.

Ping Gaoyi silently landed on the roof of the post station.

He crouched on it and quietly looked at the two groups of soldiers patrolling below, and after confirming that no one had noticed, he made an upside-down golden hook, hooked the corners of the eaves under his head and feet, and went to the window of the room where Lao Cheng was killed, and inserted the thin iron sheet he held in his hand into the gap.

With a slight "click", the sash opened.

Like a swimming fish, Ping Gaoyi slid into the window with a twist, and then quickly turned around and closed the sash again.

The whole process was just a breath, and the movements were smooth, except for the slight "squeak" sound of the window opening and closing, there was no other sound.

Ping Gaoyi didn't dare to light a candle, so his eyes widened and he took a closer look in the room.

I saw that on the wall was the eye-catching line of words - Tubo treachery, everyone will be punished!

Then there were the crooked tables, chairs, and benches, and the large pool of blood, which still smelled of rust.

Ping Gaoyi carefully flickered around the room, trying not to touch anything, and walked all the way to the door.

He probed inch by inch with his hands, and found a newly made door latch that was still a little rough, and then squatted down to look for it again, and sure enough, he found the old door latch that had been broken in two by a sharp blade.

It seems that the murderer broke into the door directly, and then the two had a fierce fight, disrupting the layout of the house.

Or maybe it's more than two.

In the end, Cheng Feng was defeated and was pierced through the abdomen with a knife.

Wait a minute!

Something is not right!

Ping Gaoyi stopped and thought quietly.

Cheng Feng was a veteran of the battlefield, and he was so determined that he would not take the initiative to confide in any information, so he died.

There is nothing to doubt about this.

But what the killer did after the murder was a little strange.

If he really regarded Lao Cheng as a spy, he should report it to the government, at least he shouldn't just leave.

Unless, the murderer has another plan to find Lao Cheng!

When the murderer doesn't get what he wants, he won't kill Lao Cheng!

How did Lao Cheng die?

Suicide, perhaps? It's possible.

Why did the murderer leave blood on the wall when he didn't get what he wanted?

Paint a false picture? Misfortune to the east?

The only thing that is certain is that the murderer will not give up, and he or they will definitely find someone who has contact with Lao Cheng again.

In addition to Lao Cheng being a conscientious post, only his identity as a supernumerary spy of Lingling Water Pavilion is the most valuable.

The murderer's purpose is to find or destroy the secret channel of information transmission established by General Feng!

In this way, the identity of the murderer is about to be revealed!

He is the real Tibetan spy!

In order to cut off the transmission of Tibetan news to the army here, Cheng Feng was found!

From the perspective of Lao Cheng's business, since he is an undercover spy who delivers news to the outside world, there must be another person on it as his source.

The murderer's purpose has not been achieved, so he will continue to look for it, so Cheng Feng's superiors are in danger!

There is also the news that was not passed on by Cheng Feng, the news that Fang Tai inadvertently saw - ten days later, Tubo came.

Under what circumstances can the Tibetan envoys be allowed to deliver the news in person, and what are they planning?

And most importantly, there is one more important point.

How was Cheng Feng exposed?

Ping Gaoyi's mind turned sharply, all kinds of thoughts came one after another, and he felt that there was a big net shrouded in Nanxi County, boundless and heavy.

He took a few quick breaths and pulled his mind back.

These news and inferences have to be transmitted to the above in time, and they must be told to Fangtai!

The water in Nanxi County is too deep, so we must be more careful and prepare for everything.

Thinking so, Ping Gaoyi returned to the window, intending to return the way he came.

He pressed his hand lightly on the window sash, but suddenly froze.
