"How do you know? You've checked them all here?" Ao Yu's dragon soul couldn't explore the entire barracks. Pen & Fun & Pavilion www.biquge.info

"If you want to read more books, you won't want to learn the rules in the army, just calculate it. Normal barracks do not set up more than one forage yard, and the garrison stores forage for no less than seven days, including mules, horses, cattle and other cattle for pulling carts of livestock. Based on the stock here, the barracks and the cavalry in the pass do not exceed 2,500, and the transportation capacity cannot guarantee the use of 20,000 troops.

Even if the task of transporting supplies is carried out by the rear, in the event of a fierce battle, the load of transportation will increase exponentially, and the overstaffing of the barracks will become mortal wounds, and the lack of supplies will lead to the discouragement of the army and large-scale non-combat attrition. There should not be such a big hole in a long-term garrison barracks, so the size of the garrison here is about 10,000 to 15 thousand people. "Ding Kui's experience is not limited to combat.

"Human warfare is complicated, and dragons need to think about it so much. Ao Yu could understand every word, but he didn't understand the meaning, and it was a complete waste of Ding Kui's bitter words.

"Well, when I didn't say it. Let's go and find the water source of the camp, I don't know if I can make a fuss about the water source. Ding Kui knew Ao Yu's virtue and did not forget his mission.

Zhenbeiguan is only more than 20 miles away from the swamp, and the groundwater resources are quite abundant, and the defenders rely on well water to solve the problem of water use.

Ding Kui and Ao Yu could walk through most areas of the camp at will, and they carefully avoided those places where there was a possibility of high-level combat power.

The water film that can refract light in the Qinglong layer is rarely used in front of humans, and those who know it have basically escaped from the category of human beings, not to mention the military camp of the Meng army, all the military camps in the entire continent have no measures to prevent this kind of ability.

Except for the vital point, the archers and magicians did not have a detection mechanism inside the barracks, and they did not believe that anyone could avoid the eyes and ears of everyone in the barracks.

However, there are two outliers in this world, Ding Kui and Ao Yu, who have tried stealth operations in many Shaodian military camps, and now they are familiar with the road in the Zhenbeiguan military camp, walking around the areas they think are safe in full view.

"It was the 23rd Division of the Third Army Corps of Meng who was stationed here. "Ding Kui, who has been in the barracks for a day, can be sure.

"I don't feel like there's a master. After leaving the swamp, Ao Yu's panicked feeling disappeared, and his body began to regain his arrogance.

"The master should be in the pass, let's go in and take a look. ”

The final destination of the special operations brigade is not the barracks, and it is useless to occupy the barracks even if they cannot enter the pass.

The nine gates of the "Helian Jade Wall" were all built into castles, and the gate facing outward was often closed, and no one had the right to open it without the order of the supreme commander of the castle, and the gate facing inward was open during the day and closed tightly after nightfall.

Ding Kui and Ao Yu followed a patrol into Zhenbei Pass, and for the first time, Shaodian military personnel infiltrated the military fortress of the Meng army.

The castle was full of Meng guards, and there were torches and oil lamps everywhere, and Ding Kui speculated that there would be no dark corners even at night.

"Hey, a lot of traps are trapped, but fortunately, I learned a little from Grandpa Qian, and I can see it from the following arrangements of the wind archers. Ding Kui pulled Ao Yu to stand in the middle of the atrium, which was the place with the least number of guards.

"My God, there are at least two brigades in the caves on both sides of the gate. Ding Kui saw their final destination.

"There was a window on the wall of the gate that was attacking inward. "Ao Yu doesn't know anything, he pays attention to things related to him, and the responsibility of opening the door will fall on him if there is no accident.

"No matter how much, I'll write it down first. Ding Kui didn't dare to scan with mental power casually, and only forcibly wrote down everything he saw in the castle through his eyes.

Woo, a low horn sounded, the castle's inward-facing gate slowly closed, and several teams of soldiers armed with torches lit up the castle lighting points one by one.

Ding Kui and Ao Yu slipped to the vicinity of the large kitchen, where the castle guards were most lax.

"It just so happened that I was a little hungry. Ao Yu's eyes glowed.

"It's good to steal a little bit, don't go too far, otherwise it's easy to be discovered, and it's not easy to escape from here." Ding Kui had to be told again and again.

The big kitchen was preparing dinner, and the cooks and servants were so busy that no one bothered to take care of the room where the food was stored, giving Ding Kui and Ao Yu a vacancy.

Ding Kui took out a pen and paper from the ring, made some simple marks, let Ao Yu steal food, and helped him keep watch by the way.

"Well, there's a lot of food being sent from these directions. At this time, Ding Kui dared to release his spiritual power to observe, no magician would pay attention to the kitchen when eating, "Oh, the ingredients sent from those directions are more advanced." He observed and recorded it.

"You're a thief, come to this place to gather intelligence. Ao Yu had to admire Ding Kui.

"The army is a place where rules are spoken, as long as you can find the thread, you can deduce a lot of information, eating is an activity that everyone has to do every day, this habit is inconvenient to change every day, and it is the most stable one among the many threads. Ding Kui was complacent, and he was in the mood to explain to Ao Yu.

"Where there is a lot of food, it is possible that there are people like me. Ao Yu offered his opinion.

"There is a possibility, but the probability of having a dragon in the garrison is too low to be negligible, there are people who are stronger than you, but there is absolutely no one who has a diet comparable to you. ”

"Someone is coming. Ao Yu rushed to Ding Kui's side with an arrow step, and reached out to press Ding Kui's shoulder.

Two servants entered the room, one of them carrying a bag of grain and hurried out of the room, not noticing that there were two other people in the room.

When the servant was far away, Ao Yu let go of his hand and said, "It is impossible for you to sneak into the castle with that group of ants. ”

"Squat down tonight and see if there is such a tight defense all night. Ding Kui frowned, "A small number of people can blend in, and it is indeed a very difficult thing to get all the people in." ”

After dinner, the cook and servants returned to their rooms, and a small group of guards entered the kitchen and patrolled the room. The lights in all the empty rooms were still on, and no one came to extinguish them.

"It seems that the guards in the castle are much tighter than I thought. Ding Kui had an even more headache when he saw this.

"Hmm, there's a magician's mental power sweeping over. Ao Yu's expression also became serious.

"Luckily, his rank is so low that I can't even notice it. Ding Kui breathed a sigh of relief and wiped the sweat of his palms on his pants, "Let's go to the atrium, we are safest there." ”
