In fact, Liu Zhao and the Ministry of Intelligence do not need to be so thorough, or they do not need to be so cautious, because in this era, there is almost no intelligence, espionage, etc., and even Datang does not have a professional intelligence agency, let alone other countries around.

Regarding joints and other aspects, it is basically equivalent to nothing, and as for some yamen with similar functions, they are more in a very primitive state.

The portrayal of some ancient intelligence agencies in many film and television dramas in later generations is actually artistic processing after the impact of modern spies.

After all, in this era, you want to disguise an ordinary person, unless you really have been doing it for a long time, otherwise you want to disguise, it will be like a firefly in the night, too obvious.

Skin, clothes, state, eyes and other aspects, as long as you don't do this for a long time, and then throw it into the crowd, it is really unusually conspicuous, and no disguise can be disguised at all.

The reason why these people in Yuelai Commercial Bank can be disguised is because they are engaged in these industries in Yuelai Commercial Bank, and they are basically poor people before joining Yuelai Commercial Bank.

They are only trained in their minds, but the work in their hands has basically not changed.

Therefore, the people of this era do not have this consciousness at all.

But Liu Zhao: They have always been so careful because the Datang Intelligence Department is so careful, of course they have to be careful.

In fact, Yuangai Suwen is not in this city, Liu Zhao dare not say that it is the largest in the city, but in this city within Yuangai Suwen's sphere of influence, he basically belongs to the category that no one dares to provoke.

Therefore, no one doubts what he did.

The owner of the restaurant is a Goguryeo, of course, at least on the surface.

Since Goguryeo has always used Chinese characters, and most of the Chinese characters are spoken, there is no problem in saying Chinese characters and the like here.

In a secret private room of the Food for the Sky Inn, this private room has undergone special soundproofing and thickening decoration when it is renovated, and it is also in the innermost part of the restaurant, which is generally not open to the public.

"Mr. Liu Zhao, the Tang Dynasty now needs you to provide our own villages, as well as what you know about the deployment of troops in Goguryeo." The shopkeeper of Shi Weitian took out an incomparably detailed map of Goguryeo and put it on the table.

This large map is also very well preserved.

Liu Zhao nodded, and then asked with some excitement: "Is Datang going to do something to Goguryeo?" ”

Because Goguryeo's envoys have not yet returned to the capital of Goguryeo, Goguryeo does not know now, and if the Tang Dynasty does it directly now, it is estimated that it will be able to occupy a lot of advantages.

But there are some advantages that are not necessarily taken advantage of, and when you are ready, you will have a greater advantage.

If we rush into the army now, the number of non-combat attrition that may be caused will increase dramatically! To know how cold the winter in the Tohoku was in later times, the average temperature in this period was at least about 5 degrees Celsius lower than the winter in the later Tohoku.

And the warmth measures of this era are not comparable with later generations, although it is said that all the army cotton clothes in the Tang Dynasty have been distributed, but once the army marches and fights, cotton clothes alone cannot withstand the cold of the night.

So it's safer to make all the preparations in advance and wait until the weather warms up before going straight to the attack.

"Yes, the Tang Dynasty has declared war on Goguryeo, and now the envoys of Goguryeo are on their way back to Goguryeo, and the forces of the Tang Dynasty have gradually begun to advance towards the border between the two countries." The shopkeeper did not hide the news from Liu Zhao.

Because what Liu Zhao did was treason to Goguryeo, he must be a Tang Dynastyman.

"Okay, no problem, I want to check with you about all the villages and the deployment of troops first." Liu Zhao said quickly.

It took the two men more than an hour to check all the villages and the deployment of troops. Looking at the specially marked villages on the map, the shopkeeper said seriously: "These places will pay special attention when the Tang Dynasty attacks, and they will not hurt the ordinary people in these places, you can rest assured." ”

"I know that I have been paying attention to the news of Datang in the past few years, and we all know the changes of His Royal Highness to the people of Datang, in fact, near the border of Datang, many people of Goguryeo have secretly fled to Datang."

"Therefore, in these villages, especially those close to the border between the two countries and those with more Han Chinese, in fact, our Datang has a natural sense of closeness, as long as it is not coerced by Goguryeo soldiers, it will basically not cause any harm to Datang."

"In addition, these villages I specifically explained, they have all become our people completely, in these villages do not have to worry about leaking rumors, if there are some scouts, secret agents, etc., you can go to these places, I have already told you the agreed secret words, you should be very clear." Liu Zhao said seriously.

"Well, no problem, but the war is coming soon, and the utilization rate of these villages will definitely increase, so you should explain it to the people in these villages in advance when the time comes." The shopkeeper explained again.

"No problem, I'll arrange it when I get back." Liu Zhao nodded.

"Datang...... Have faith? If I need to attack any city at that time, I think I can send someone to cooperate in advance. Liu Zhao thought for a moment, then gritted his teeth and said.

"Do you have a lot of soldiers?" The shopkeeper asked.

"It's not much, we only have more than 3,000 soldiers, which is hardly worth mentioning in the entire Goguryeo army. The first reason is that we put our main energy on the common people, and the second is that Yuangai Suwen is very cautious in controlling the army, and although we are from the army, we don't have much opportunity to cross paths with the armies scattered in most other regions. ”

"But...... When the Tang Dynasty was attacking, if it could cause fewer casualties, it would be as few casualties as possible, after all, some of those soldiers were also born in these people's families. Liu Zhao shook his head and said.

"Then forget it, then, when the time comes to attack any city, I will tell you in advance that you will arrange for your men to avoid the main direction of attack. Because once a war starts, sometimes it is impossible to control the situation. The shopkeeper thought for a moment.

"I see. That's it, I have to go back, I can't leave for too long. ”

"I'll send you." After sending Liu Zhao out to eat for the day, the shopkeeper immediately arranged for someone to send the map back to Datang as quickly as possible.
