In the face of Lei Dashan's inquiry, Yu Xiyan said: "After all, Arogan and I are grassland people, although we have been in Chang'an for two years, our living habits are still different from those of the Central Plains, even if we live in the houses of the Central Plains people, we still have to make some small changes to make ourselves comfortable, I can start to find out Arogan from this aspect!" ”

After hearing this, Lei Dashan looked at He Yong and asked, "What does He Gong think?" ”

He Yong said: "If a large-scale investigation is carried out again, I am worried that the grass will startle the snake!" Now that we know that they are in the Recreation Place, we simply set up monitoring points and reserve teams at the main intersections around the Recreation Place, and conduct uninterrupted surveillance for 12 hours a day. ”

Lei Dashan thought about it for a while and agreed: "Okay, just do it!" ”

The two discussed it for a while, and immediately began to deploy, and asked the medical officer to treat the wound and take him to the scene for identification.

There is a watchtower at the intersection of each main road in Chang'an City, there are Jinwuwei guards on it to monitor, standing on the watchtower, the surrounding situation is clear at a glance, what happens in any position can be seen at a glance, the Jinwuwei armor on duty below the watchtower can quickly rush over, this is since the Hu people and the local people had a conflict, the left and right Jinwuwei Yamen quickly organized manpower and material resources to build up, like such a watchtower, there are more than 200 in Chang'an City.

In addition, between the watchtower and the watchtower, the big city gate, the small city gate, the big square, the small square set up the Wuhou shop, equipped with the number of Wuhou varies, responsible for public security patrols and fire fighting, under the jurisdiction of the left and right Jin Wuwei subordinate to the left and right Yi Fu.

Although they all belong to the left and right Jinwuwei under the control, but the nature of the Jinwu guards and the Wuhou is different, the Jinwu guards belong to the mobile armed forces, equivalent to the armed police, every day need to drill and change the guard, the night street patrol is mainly responsible for the Jinwu guards, and they are generally on standby during the day; Wuhou, on the other hand, is equivalent to a complex of police, urban management and firefighters, basically only during the day.

In a watchtower on the street of Kangle Fang, Lei Dashan said to He Yong: "This is the closest intersection between Kangle Fang and the city gate, if Ah Luogan and Tan Wuye want to go out of the city, the probability of passing through here is more than eighty percent!" ”

At the end of the day, Lei Dashan, He Yong and others who were squatting here found nothing.

After the city gate was closed, it was already dark at this time, someone brought food and water, the soldiers and catchers were eating below, Lei Dashan and He Yong were still staring at the watchtower.

He Yong said while eating: "Lao Lei, there is a situation that I don't know if you have thought about it!" ”

"What's the situation?"

He Yong said: "If Arogan and Tan Wuye are not together, and we only found one of them, how do you think we should deal with this situation?" ”

Lei Dashan really didn't think that this might happen, but in such a tense situation now, it is very likely that the two of them will scatter and flee!

"You mean they're likely going to go out of town separately?"

"It's entirely possible, if they go out of town together, once they are discovered, both of them will be finished!"

Lei Dashan thought for a while, looked up at He Yong, and said: "I mean that once only one appears, we have to put up with it for the time being, put a long line to catch big fish, even if they disperse out of the city, they will definitely meet at a certain location!" All we need to do is keep an eye on the person who shows up, and the other person will take the initiative to join them, and then we will act to catch them! ”

He Yong smiled: "I think so too, let's discuss the specific details······

For two days, he didn't find the figures of Arogan and Tan Wuye, Lei Dashan, who was squatting in the watchtower, was not discouraged, he was confident that as long as Arogan appeared, he would definitely not be able to hide his sharp eyes, and until now he had not found the figures of Arogan and Tan Wuye, which could only mean that they were still waiting for the opportunity.

On the morning of the third day, at the end of the day,

Just then, a carriage stopped at the mouth of an alley.

Lei Dashan glanced at it, his gaze just swept over, and quickly turned back, "Hey, this carriage is a little familiar!" ”

A catcher next to him quickly said: "I know, I have seen it in the embassy, this is the carriage of Huang Guangyao, the envoy of the Southern Dynasty!" ”

Everyone in the watchtower was attracted by his words and looked at the carriage.

At this time, a man in a cloak came out of the alley, and Yu Xiyan's eyes suddenly widened, "It's him!" It's definitely him! ”

Lei Dashan was stunned, "Who?" ”

"O Arogan, although he covered his head with a robe, I recognized the way he walked, and you can see his shoes, which are boots that only the nobles of Rouran can wear!"

The watchtower people swept away the previous decline at this moment, and they became energetic one by one, and the silent squatting for several days finally waited for this guy.

"Why is he the only one? What about Tan Wuye? Someone next to him wondered.

Lei Dashan saw the cloaked man get into Huang Guangyao's carriage, the carriage began to start, he turned his head and ordered to the catcher beside him: "Lao Liu, you quickly ride a fast horse and make a detour to the city gate to tell He Yong, just say that A Luo Gan has appeared, and the carriage of Huang Guangyao, the envoy of the Southern Dynasty, is heading towards the city gate!" But Tan Wuye has not yet appeared, I have decided to wait for another cup of tea, and if the time of a cup of tea has not yet appeared, let him proceed according to the strategy we agreed before! ”

"Yes!" Lao Liu hugged his fists and agreed, ran down the watchtower with his fists, led a horse from the side and stepped up and galloped away from the alley next to him.

Lei Dashan said again: "Ah Bing, you take two people to follow the carriage in civilian clothes, don't follow too closely, but you can't let the carriage get out of your sight!" ”

"Understood!"

After waiting for another moment or so, Lei Dashan saw that there was no movement, and Tan Wuye never appeared, so he had to leave a few people to continue to monitor, and then personally led his men to the direction of the city gate.

City gates.

The carriage of the envoy Huang Guangyao of the Southern Dynasty was not too conspicuous in a long line of carriages waiting to leave the city, after all, there were too many princes, nobles and high-ranking officials and generals in Chang'an City, and the carriage of an envoy was also general in terms of regulation.

On the city tower, He Yong saw the carriage, and he looked at the end of the street, but found that Lei Dashan had not yet come, did he send someone, it seems that Arogan and Tan Wuye are really separated.

He Yong quickly ordered his subordinates: "You go and tell the soldier in charge of checking the car, don't be too serious when you find Huang Guangyao's carriage later, even if you really find something, pretend not to find it, and let them out of the city!" ”

"Understood!"

It didn't take long for Huang Guangyao's carriage to arrive at the gate of the city, and the soldier stopped the carriage with his sword, asked him as usual, and then began to inspect it, and he lifted the curtain with his scabbard to look inside.

At this time, a carriage behind it suddenly caught fire, and the smoke was billowing out, and the people around were frightened and fled in all directions.

The head of the soldier immediately lowered the curtain of the car, like a fly: "Hurry up, go, don't be burned!" ”

The barricades were removed, and the coachman immediately drove the carriage out of the city, and Huang Guangyao and A Luogan in the carriage breathed a sigh of relief, as long as they were out of the city, it would be easier to hide.

He Yong, who was on the city tower, made a gesture to the two plainclothes spies at the foot of the city wall outside the city, and the two nodded, hanging far behind the carriage.

"This official will bring someone to follow, you two will stay and wait for Lei Dashan, if he comes, you will take them with you to join me!" He Yong briefly explained a few words, and hurried out of the city with a large number of people.

······

Xiwei Bridge, South Bridgehead.

There are many pavilions built around, and some vendors set up stalls around, and there are many officials, officials, literati and ordinary people standing here, which seems to be very lively.

Why is there so much excitement around the south bridgehead of this Xiwei Bridge? Just because this is a place to send off guests!

Xiwei Bridge is also known as the Ben Bridge, in the Han Dynasty it is far away from the first gate in the southwest of Chang'an City, so it is also called the Ben Gate, and the people also call it Xianyang Bridge.

Before Lei Dashan approached the south bridge head of the Xiwei Bridge, a man rushed out from the side of the road and stopped him and his men.

The group hid in the grass next to them, and Lei Dashan was brought to He Yong's side.

"What's the situation?" Lei Dashan asked.

He Yong said in a low voice: "A Luogan didn't cross the bridge, he got off the carriage at the bridge, and seemed to be waiting for someone!" ”

Lei Dashan looked at it, and sure enough, he saw a man in a gray robe and cloak sitting in a wine shop, drinking alone.

After waiting for half an hour, a carriage came to a stop in front of the wine shop, and Arogan, who was eating, heard the shout, turned his head to look at it, and immediately reached into his arms, grabbed a few copper coins, threw them on the table, and quickly got into the carriage.

Lei Dashan, who was hiding in the grass, immediately said: "Tan Wuye must be in the carriage, we will chase!" ”

He Yong nodded, got up and waved his hand, and everyone came out of the grass and approached the bridge.

"Don't worry, I have arranged people at the bridge, and they can't run away!"

Inside the carriage, Arogan looked at Tan Wuye and said, "It's finally time for you, I thought you wouldn't be able to get out of the city!" ”

"The gate of the city was checked too strictly, and I threatened him with the safety of this old man's family, and he was willing to agree to take me out of the city!" Tan Wuye raised his palms and recited: "Amitabha!" ”

Arogan groaned, took out a tarpaulin package and a wrench from his bosom and handed it to Tan Wuye and said: "Master, we have to pass through a lot of passes on this way to Mobei, and we will definitely encounter a lot of dangers, I am worried that I may encounter accidents, you are strong in martial arts, I will hand over this alliance with the Southern Dynasties and my personal token to you for safekeeping, in case I unfortunately die on the way, you can take them to Mobei to see our Khan and give this to him, I believe that the Khan will definitely reuse the master!" ”

Tan Wuye was silent for a moment, nodded and put it into his arms.

At this moment, the carriage stopped.

Tan Wuye asked in a low voice, "Why did you stop?" ”

"Buddha, it's not that you don't want to go, but you can't go!" The coachman immediately jumped out of the car and ran to the side to hide.

Tan Wuye lifted the curtain of the car and took a look, only to see two rows of armor soldiers holding shields and spears and war knives at the bridgehead in front of him, and a row of crossbowmen blocking the bridgehead behind him.
