According to the "Espionage Strategy" compiled by the Joint Investigation Department of the Great Song Dynasty, the real names, identities, and origins of colleagues should not be disclosed to unrelated persons, which is the rule that every spy of the Great Song Dynasty must follow.

Zhao Tan was originally an ordinary Song man who was plundered to White Frost City, and three years ago, he saved a Song spy by chance and successfully helped him escape, thus making a great contribution.

After passing the school many times and being recommended by the Song spy, Zhao Tan also became a hidden spy of the Great Song Dynasty, and was exceptionally included in the command of the Joint Investigation Department of the Great Song Dynasty, serving as the captain of the "Changfeng Battalion".

And the Changfeng Camp is the place where the Great Song Dynasty specializes in cultivating spies.

The full name of the Great Song Dynasty Joint Investigation Department is the "Great Song Dynasty Joint Investigation Department", which is an official office of the previous Han Dynasty and is personally run by His Majesty the Emperor.

Eleven years ago, the Joint Investigation Department secretly established a hidden army, the Changfeng Battalion.

"The blade is like a sword, and it goes straight to the back of the enemy's prisoner; The lonely army is deep, and there is no question of the way back. ”

This is the day when the Changfeng Camp was established, and Song Taizu personally inscribed the words on the stone sword in the middle of the camp.

Since its establishment, countless Changfeng soldiers have gone to enemy countries to spy on military intelligence, transmit news, and help the Great Song Dynasty resist foreign invasions.

Although the battles on the battlefield are magnificent, those battles hidden in the shadows are also as dangerous and tragic as the former. Many of the long-bladed soldiers died silently, and their names were not even known.

However, they continued to move forward, even if they walked on the tip of the sword, they were not afraid.

"Born like a long front, the deceased is nameless", this is the law that every Changfeng soldier must recite when entering the camp, and it is also the belief held by all Song spies.

"Zhao Tan and I originally agreed that Shen Chu would meet in the old place, and then I would secretly embellish him and Aqi...... Well, it's a meeting with Miss Wei. But I waited until more than half of Shen Chu yesterday and didn't see his people, and I was very worried. Zhou Shang said.

His tone was a little low, and there was a hint of remorse in his gaze when he looked out the window:

"I shouldn't have listened to Lao Zhao. He insisted that he would reveal a little more of his news to Aki...... to Miss Wei, and said that he must show up in person to hand over the drawings, otherwise Miss Wei is afraid that she will not take the bait, and I was moved by him. ”

"He's right." Ye Fei took over the conversation, and the action of wiping the axe followed: "If you want to win big enough and enough, you must be willing to pay the capital, otherwise who will bet with you?" ”

Zhou Shang was silent for a moment, as if he agreed with his boss's words, and soon continued:

"I didn't dare to go to the empty house in the north of the city where Zhao Tan and Aqisi had an appointment, but I went to Balan's house first, but I didn't hear anything. I went back to the place I agreed with Lao Zhao, and waited for him to have about two sticks of incense, but he still didn't come, I looked around, but I didn't find the mark he left. ”

The "Balan family" in his language refers to the home of Zhao Tan's envoy on an errand, and the name of the Jin official is called Buri Balan.

I only heard Zhou Shang say at this time: "At that time, it was close to the time of Shen Zheng, and nearly two moments had passed since the time agreed between Zhao Tan and Aqisi, so I ventured to the empty house in the north of the city, and found that there was no one to be found in that place, and there were no suspicious marks, so I returned here and took down the iron horse hanging outside the door." ”

As he spoke, Zhou Shang stared at the alley outside the small window, and only pointed to the location of the east window of the house.

There is a bamboo curtain hanging from the east window, the bamboo color is already a little yellow, and under the curtain is an iron horse Zhanfeng Duo.

The iron horse was about a foot and a half long, with four hooves soaring and an ancient shape, and the dim light of the sky fell through the cracks in the bamboo curtains, shining on the mottled rust on it.

"Yay." Ye Fei raised his eyes to look at Zhou Shang, and there was obvious approval in his eyes: "The benefits are not small, Old Zhou." You knew how to move forward, and now you know how to do it. ”

"Lord Xiao Lu has taught me for so long, no matter how stupid I am, I should learn." Zhou Shang's eyes did not leave the window, and the smile on his face looked a little reluctant:

"When I came back here yesterday, I thought that Zhao Tan and I were both exposed, that Zhao Tan had been captured and that someone was staring at me in the dark. I thought, it doesn't matter if this place is raided, at least you can all survive. ”

Zhou and Ye are only people who come out to make contact, and a stinging spy like Zhao Tan rarely meets them.

According to the "Law of Espionage", except for the transmission of important information or necessary secret meetings, spies should meet with each other as much as possible, preferably not at all, and only pass messages to each other in signs and codes.

The Iron Horse Zhanfeng Duo is a warning signal agreed in advance, and if it hangs, it will be safe, and if it falls, it will be dangerous. Zhou Shang is using this to inform his colleagues:

It's dangerous, it's a fast getaway.

When he returned here at dusk yesterday and took down the Iron Horse Fengduo, he actually had the heart of death, and "the two of us can live the whole situation" was his only thought at that time.

But the development of events is far beyond his expectations, and today's events are also the aftermath of yesterday's events.

"Lord Xiao Lu does have the ability, and he has thought of everything for us." Ye Fei said at this time, with a hint of admiration on his face:

"I also learned from him that going behind enemy lines is not only the 'three caves of cunning rabbits', but also 'you don't know my cave, and I don't know your cave';

Only in this way can we reduce casualties and leak more information in times of crisis, and even if we are captured, we will not be afraid of torture but will confess our companions or secrets, because—"

He suddenly paused, and Zhou Shang immediately took over the conversation in a timely manner:

"Ignorance is the best way to keep secrets."

"Exactly." Ye Fei smiled faintly, picked up the sweat towel and continued to wipe the short axe, and said, "You go on." ”

Zhou Shang pondered for a moment, as if recalling yesterday's situation, and then continued:

"I waited here until the beginning of the unitary period, and I felt that things didn't seem to be as I thought, and I was still a little uneasy, so I went around three times outside, interspersed with a dozen alleys, changed my outfits, and repeatedly investigated and considered, and then I guessed that maybe no one was staring at my tip."

"You didn't leave a mark, did you?" Ye Fei glanced up at him.

It's not so much that he's asking, it's more like a boss's examination of his subordinates.

Zhou Shang immediately shook his head and said, "I haven't stayed." In the end, that's just my own speculation, in case a gold master secretly embellishes me and learns our mark, it won't be my own disaster, but everyone will be in danger. ”

Ye Fei was very satisfied, and said, "Good job." You continue. ”

Zhou Shang said again: "After I found out that no one was staring at me, I thought, maybe Zhao Tan is as safe as me, but he was stumped by something in the house, so he couldn't go to the appointment."

Since there was still some time before the curfew, I hurried a cart of charcoal to Baran Mansion, and stopped by Zhao Tan's residence to have a look. His room was empty, the bedding was neat, and there was nothing unusual in my eyes, but I was always a little bit on the ground in my heart. ”

Zhou Shang and Ye Fei's identities to the outside world are merchants, because their business is quite large, they often go in and out of the major mansions in White Frost City, and it is easy to inquire about some news.

After stopping his words, Zhou Shang breathed out a few deep breaths, as if gathering courage, and finally said, "I suspect that Zhao Tan disappeared the night before yesterday." ”
