Looking at the castle tower from here, you can already clearly see the faces of the soldiers defending the city. There are high lanterns hanging on the city tower, and bright torches are inserted on the battlements, but because Youzhou City is too big, it is impossible for every battlement to have torches, but there is only one more than ten steps apart. In general, the light is still not strong enough, which makes Leng Yi feel dark in their hearts. Groups of soldiers patrolled back and forth on the city walls, and observation posts looked down. However, because there was no light below them, and the light of the torches and lanterns did not shine on the ground, let alone on the other side of the moat, which was more than ten zhang wide, they could not see the three of them.

They chose the corner of the wall, which was easier to climb and at the same time, they could use the corner to avoid the gaze of the soldiers who came out to probe. Although they did not find any soldiers doing this. But in the end, you have to be prepared.

The three of them had already discussed how to cross the moat, and when they crossed the antler barrier, they had already pulled out some thick branches, and at that moment, Bai Hong, who was as light as a swallow, threw the branches into the moat in turn, and then passed like a dragonfly.

The branches of the footsteps are thicker and provide a place and strength for them to step on. Zhao Hongrust and Leng Yi both passed, although their postures were not as graceful as Bai Hong's, and they even got their shoes wet.

When he arrived at the city tower, Leng Yi looked up at the city wall, and exclaimed in his heart: It's so high! This Youzhou city wall is even three points higher than the city wall of Bianjing City. Obviously, Youzhou City served as the gateway to the Great Song Dynasty, and the Liao army attached great importance to the construction of Youzhou City's city defense. In the decades since taking over Youzhou, the city defense of Youzhou City has been strengthened and heightened.

Leng Yi was wearing a rope. Grasp the corner of the city wall and slowly climb up. He didn't dare to use pitons because it would make a noise. To attract the attention of the enemy, you can only climb with your bare hands, without any protection. Once lost, if you fall from such a high wall, you will definitely die!

Leng Yi mobilized all the sensations in his body, on the one hand, he had to pay attention to the movements of his hands and feet, and on the other hand, he had to pay attention to the situation of the Liao army guards on the city tower. Always ready to dodge and hide. Fortunately, the Liao army did not conduct too close investigations. No soldier came out to look at the wall. Therefore, Leng Yi went all the way relatively smoothly, and finally climbed to the battlement of the city tower without danger.

He cautiously probed to inspect the city walls, and there were piles of rolling logs, stones, bed crossbows, and other equipment to defend the city. As well as a large mountain of bows and arrows. This made Leng Yi's heart sink.

There were no guards around the corner. The Liao army patrols in the city were not too dense, and there was about half a cup of tea (two or three minutes) between each team. Although this time is short, it is enough for the three of them to pass.

Leng Yi took advantage of the interval between the two patrols to drive two pitons into the gap in the city wall. Tie the ropes. Fixing himself, and then throwing down the climbing rope, Bai Hong and Zhao Hongrust climbed up in turn and hung outside the city wall. Leng Yi put away the rope and observed the interval of the Liao army patrol, and the three of them fluttered over the battlements, using the defensive equipment and weapons piled up everywhere on the city wall as cover, and quickly passed through the wide city wall. Turned over and hung on the other side of the wall.

Leng Yi hung the two of them with a rope, and then collected the rope. Climb slowly on your own.

Entering the dark and silent street, Leng Yi and the others breathed a sigh of relief. Zhao Hongyu said in a low voice: "You are so powerful, you really came in." Now, what are we going to explore? ”

"The number of garrisons and grain and grass of the Liao army. This is the most important thing, as well as the equipment and location of their city defenses. In order to save time, let's split up. Bai Hong and I will explore the left, and grandpa, you will explore the right. It's an hour, so be careful not to disturb the enemy! Meet here at the fifth watch! ”

Bai Hong and Zhao Hongrust nodded, and the three of them divided into two groups, taking advantage of the night to set off in different directions on the left and right.

Leng Yi and Bai Hong moved forward quickly against the side of the street, and there was obviously a curfew in the city, and there was no one on the street. Except for the Liao army horse team that patrolled past on horseback from time to time. The sound of horses' hooves is particularly crisp in the silence of the night.

Leng Yi and Bai Hong dodged these patrol horses and walked all the way.

Bai Hong was really familiar with Youzhou, and took Leng Yi to turn east and west, and after a while, he came to a high wall. Bai Hong said in a low voice: "This is one of the Liao army barracks, and there are twelve such barracks in the entire Youzhou. ”

"Let's go in and take a look, I want to know how many people are inside, and calculate how many enemy troops are defending the city."

Bai Hong nodded.

This wall is not too high, so there is no need for Leng Yi to climb up first, Bai Hong flew out of the zipline, went up lightly, and then hung Leng Yi up, and then climbed over the wall.

Around this barracks, rows of barracks are neatly arranged, and in the middle is an empty exercise ground. It was late at night, and there was not a single figure in the barracks except for the sentries on the arrow stacks.

Leng Yi pointed at himself, then to the left, then to Bai Hong, and then to the right, signaling to move separately.

Bai Hong nodded, and the two went separately to investigate.

Leng Yi came to the nearest barracks. I dipped my fingers in saliva and wet the window paper, poked a hole, and looked inside. Through the misty night, I vaguely saw that inside was a long chase shop that could sleep dozens of people, and on it were sleeping Liao soldiers, snoring one after another, and the sound of grinding teeth.

Leng Yi counted carefully, there were about a hundred soldiers in this room.

Leng Yi and Bai Hong quickly counted and got together and calculated, there were about 10,000 soldiers in this camp! Moreover, the two also found that there were a lot of defensive and siege equipment in the warehouse of the barracks, and in addition, there were warehouses for storing a large amount of military rations. Judging from the amount of these military rations, it is enough for the soldiers of this barracks to eat for more than half a year!

Leng Yi asked Bai Hong in a low voice, "Are the other barracks about the same size?" ”

"I don't know, I haven't been in either, but it's pretty much the same outside."

"Well, then let's go to another barracks."

Bai Hongqi said: "What are you going to do in other barracks?" The scale is about the same, one is 10,000, 12 barracks, and the strength of Youzhou City is 120,000. Isn't that what it takes? ”

Leng Yi said in a deep voice: "Seeing is believing. What's more, there is still time, so let's explore in more detail. ”

"Alright! I'll take you. ”

Bai Hong quickly took Leng Yi to the second barracks.

Here, it is still a high wall, surrounded by high sentry stacks. There are Liao soldiers looking around from above.

The two of them still entered through a secluded corner over the wall. Then I went to the barracks window and looked at it.

Leng Yi looked into the small hole, and couldn't help but sigh, only to see that there was no one lying on the Datong bunk, which was about the same length as the previous barracks! There's not even a futon! The whole barracks was also quiet, and there was no sound!

Leng Yi immediately quietly came to the second barracks, and after inspecting it, it turned out to be the same, the room was empty!

He checked all the barracks on the left, and returned to the meeting point of the two, Bai Hong was already waiting there, and when he saw him, he said in a low voice: "Something is wrong, why is there no one!" ”

Leng Yi nodded: "It's the same on my side." Not a single one. ”

"Could it be an abandoned barracks?" Bai Hong said.

"No way, there are sentinels on the sentry stacks, and the warehouses are full of grain."

"Will you go up to the castle tower to patrol? Maybe it's their turn to defend the city today. ”

"If there's a possibility, we'll take a look."

The two of them went to the next barracks again, and this time, to their surprise again, this barracks turned out to be empty except for the sentries!

Then they quickened their speed and quickly surveyed the barracks on the left. Only the two barracks at the two ends had soldiers, and the rest were empty!

Bai Hong said: "Let's go back, shall we?" ”

Leng Yi said: "Don't worry, I'm worried that grandpa didn't look at it so carefully." So let's take a look, there's still time anyway. ”

"Good!"

So they looked at the one on their right, and they were very fast, as long as the first barracks was empty, the others were empty. So I just picked a few supplementary inspections, and not all of them. In addition, Bai Hong was very familiar with the location of the barracks, so he did not delay any time. In this way, they only exceeded a little time and rushed back to the meeting place.

Zhao Hongyu was already waiting there very anxiously, and when he saw them arriving, he said urgently: "Why are you so long?" If you don't come again, I'll go to you if I'm ready. ”

"How's it going?" Leng Yi asked.

"There are 60,000 people on my side!"

"Did you check them one by one?"

"That's not it, who has nothing to do one by one? I only looked at the first one, and their barracks are all about the same anyway. There are a total of six barracks on my side, which is naturally 60,000 people. ”

Bai Hong said with a gloomy face: "Are you so lazy? Fortunately, the officials estimated that you would be lazy, and we have checked it for you, your side is the same as ours, except for the soldiers in the two barracks at both ends, there is no one in the other barracks! ”

Zhao Hongru's eyes widened: "No!" Where did so many people go? ”

Leng Yi said in a deep voice: "I don't know, it seems that I have to grab a tongue and ask." ”

Zhao Hongyu smiled proudly: "I'm not as stupid as you think, I have already thought of this method, although I only explored one barracks, but, I scratched a tongue, but I didn't bother to ask." Ask yourselves! ”

After that, Zhao Hongrust brought up a person from the dark corner.

This person has obviously been clicked on by Zhao Hongrust, unable to move, and has a cloth stuffed in his mouth. He was tall and strong, wearing a moon-white midcoat that seemed to have been taken off the bed.

Zhao Hongyu said triumphantly: "Guess who he is?" (To be continued......)
