Zhao Junsheng also frowned when he saw the patrol soldiers and sentry guards deployed by the Rouran people on the wall, he thought for a while and asked Lu Xuanbo: "Old Lu, how long will it take you?" ”

Lu Xuanbo roughly estimated and said: "If you borrow a rope and iron hook, with the density of the existing guards and patrols, you will definitely be heard, and you can only climb the wall with your bare hands, but I need someone to copy it under the wall, and it will take about ten breaths!" ”

"Yes!" Zhao Junsheng said and said to Mulan: "Mulan, I will launch stones nearby to attract the attention of the guards of this wall, and when the guards divert their attention, you will run under the wall to give Lao Lu a chance to help him climb the wall!" ”

This wall is not only two or three meters high, but six meters high, if you want to climb it with your bare hands and climb it in such a short time, someone must borrow strength from below to Lu Xuanbo, and he should be able to climb it with the help of external force with light body skills.

"Okay, that's it!"

Zhao Junsheng saw Hua Mulan and Lu Xuanbo nodding, and immediately whispered, and then crawled to the left, searching for stones on the ground as he crawled.

After climbing nearly fifty meters, Zhao Junsheng felt that it was almost there, opposite was the southeast corner of the slave camp, there was an arrow tower here, there were three archers holding bows and arrows on the arrow tower and walking back and forth, and there were soldiers walking back and forth with weapons on the wall below both sides from time to time.

Zhao Junsheng got up and squatted on the ground, took a stone in his hand, and raised his hand to shoot at an archer on the arrow tower.

This time the stone was launched, Zhao Junsheng used internal force to push, and the strength of the stone was extremely strong, and the Rouran soldier who was shot fell on the wooden floor of the arrow tower on the spot and made a pop.

The remaining two archers were startled and immediately crouched down and shouted, "What's the matter? Wake up, wake up! ”

The shouting alarmed the nearby patrols and sentry posts, who ran towards the tower.

Finally, a defensive blank area appeared on the wall, and at this moment, Mulan quickly ran to the wall and stood in a lunge step, her hands stacked in front of her.

Lu Xuanbo rushed out of the grass like a leopard, rushing towards Mulan at a very fast speed, he stepped on Mulan's arched legs with one step, his body rose into the air, and the other foot stepped down, Mulan grabbed his feet with both hands in time, and used all his strength to lift him up and push him up.

Lu Xuanbo shot towards the walled wall like an arrow from the string, and when he was about to reach the wall, he climbed the walled wall with lightning with both hands, his body accelerated again, and he jumped onto the wall, his figure flashed and walked to the inside of the wall, and when the nearby guards were about to turn their eyes over, he had slipped down the wall of the inner wall, and disappeared into the camp in the blink of an eye.

Zhao Junsheng breathed a sigh of relief after seeing Lu Xuanbo climb the walled wall without anyone noticing, as long as he climbed the walled wall and was not discovered, he could basically avoid the sight of the guards.

He crawled back the same way, Mulan was already lying on the grass waiting, the two looked at each other, crawled back on the grass, and soon disappeared into the night.

Zhao Junsheng and Hua Mulan, who had avoided patrolling rangers and secret sentinels on the periphery, finally touched the edge of the camp of the Rouran army.

The two were lying on the grass and observing, and Mulan asked in a low voice, "Brother Junsheng, how can you know the location of those secret sentinels so accurately?" ”

"My sense of hearing and vision are different from ordinary people, as long as I am within a certain distance, I can basically perceive, and I have a stronger instinct to perceive danger than ordinary people! Shhhhh ”

Zhao Junsheng said a word and immediately closed his mouth.

A Rouran soldier yawned and walked out of the camp tent next to him, urinating in the direction where Zhao Junsheng and Hua Mulan were, and Hua Mulan immediately turned her head and closed her eyes.

Zhao Junsheng scolded in his heart: "Bad luck! ”

After the Rouran soldiers returned to the camp tent after urinating, after a full cup of tea, Zhao Junsheng pulled Hua Mulan up, and the two walked lightly and quickly along the edge of the camp, and walked for more than half a circle to the room.

The two squatted next to a hanging pot, and the firewood under the iron pot had long been extinguished.

Zhao Junsheng looked at the size of a hanging pot, this big iron pot should be able to cook more than 30 people's food at one time, that is, the number of people with one tooth.

"Mulan, you go and count how many hanging pots there are in this row, I'll count them here, and then we'll come back here to meet!" Zhao Junsheng whispered.

"Good!" Hua Mulan whispered, and immediately walked briskly along a row of hanging pots, counting as she went.

Zhao Junsheng walked briskly to the other side first, and soon came to the end, and then walked back.

After the two converged, Zhao Junsheng asked, "How much?" ”

"Ten pots!" Mulan replied.

Zhao Junsheng said: "I counted it here, there are seventeen pots, multiply the two to a total of one hundred and seventy pots, one pot can cook one tooth of food, Rouran Army has thirty-two people with one tooth like us, so calculated, the number of troops in the camp is more than 5,400 people, it should be less than 5,500 people!" ”

Hua Mulan's eyes lit up when she heard this, it turned out that this method was used to detect the number of enemy troops, and she asked excitedly: "Can you determine their number by this method?" ”

Zhao Junsheng shook his head: "Of course not, this is not enough to determine their specific number of troops, and it must be corroborated from two other aspects!" ”

Hua Mulan had a strong desire for knowledge, and she hurriedly said, "Brother Junsheng, say it quickly!" ”

"The number of tents and the number of flags!" Zhao Junsheng paused after speaking, observed the surroundings, and didn't find anyone coming, so he explained in a low voice: "Just now we went around most of the circle, I counted, there are twenty-two horizontal tents, and thirty-five tents in the vertical camp, a total of seven hundred and seventy accounts!" Excluding the tents of the commanders, the generals, and the separate tents of the little marshals and the masters, the tents for ordinary soldiers to sleep in are about five hundred and thirty tents, and ten people live in one tent, which is roughly the same as the number of troops that can be supplied by the amount of food that can be supplied by hanging pots; In addition, it is necessary to determine the number of flags, and the people of Rouran learn from our Wei army, one tooth and one flag! I counted it just now, and there are 168 strokes in total, and the strength is 5,376 men! The number of troops should be roughly the same as the actual number of troops, and even if there is a difference, it will not be too different, and it can basically be determined now! ”

Hua Mulan took a deep breath, and now she was finally relieved, and she asked again: "Do you have to corroborate these three aspects at the same time?" Do you have to infiltrate the enemy camp? It's so dangerous that Scout Scouts can count the number of tents and banners they have in the distance! ”

Zhao Junsheng asked rhetorically: "The number of camp tents and the number of flags can be fictitious, and some camp tents are empty, if you don't observe them closely, how can you know?" If you don't look closely, how can you know the exact number of stoves? If the enemy general orders to deliberately increase or decrease the number of tents and banners, the scouts will be deceived if they do not observe them closely! ”

Only then did Mulan understand that there was so much knowledge in this, she thought about it and asked, "Brother Junsheng, you didn't join the army before, why do you know so much?" ”

"Your dead future father-in-law used to be a scout captain!"

Hua Mulan remembered, "I heard my grandfather also mention that Uncle Zhao was a famous scout leader in the army when he was young, and he is very capable!" ”

"Now that it has been determined that the strength of the Rouran people has been reduced by half, and the mission of our trip has been completed, let's go back and report to General Pi!"

"Hmm!"

The two of them returned the same way again, evading the patrol of the Rouran people in great danger, and finally returned to Nantian Fort in the early hours of the morning, and the two grabbed the rope and climbed the city wall.

The leopard walked over quickly and said, "You two are finally back, nothing happened, right?" ”

"No, thank you for your concern! We have already found out, and the Rouran army is indeed less than half, and the strength of their battalion is about between 5,300 and 5,400 men! Mulan reported.

The leopard's face was murderous, "In that case, let's act according to the plan in advance and launch a night attack late tomorrow night!" I only hope that the people you sent to the slaves will succeed in inciting the slaves to respond to our night attack! ”

Early the next morning, unaware that someone had infiltrated the previous night, their mound of dirt at the bottom of the hill was finally piled up, and a large number of archers were sent up.

Under the order of Dana, the Rouran army drove the crowds of slaves to rush up, and the Rouran archers on the mound of earth shot arrows tied with ropes to the door panel of the city wall according to the previous method, and after the arrow hit the door panel, the slaves on the other side pulled hard, but could not pull it.

One by one, the defenders stretched out their long knives from between the door panels and cut the ropes on the arrows, and the Rouran people's plan was frustrated, even if they built a mound of earth, they could not break through the defenders' defenses.

A large number of slaves flocked to the city wall and began to erect wooden ladders to climb, and some slaves carried long sticks, and one sturdy slave grabbed the other end of the long stick and stepped on the outer wall of the wall and was pushed up the wall by the slaves.

A large number of arrows were shot down through the cracks in the door panels, and many slaves and Rouran soldiers were killed and wounded, and the handymen carried stones and threw them down, and many slaves were killed on the spot.

The siege was in full swing, but there was not much progress, and the Rouran soldiers and slaves were never able to climb the city walls, but suffered great losses.

Rouran Marshal was very annoyed, it took two days to pile up the mound of dirt that was useless, and the defenders fixed the door panel to death, and they couldn't pull it down.

"Keep attacking, at all costs, keep attacking!"

After a whole morning, a large number of slaves and many Rouran soldiers were killed and wounded, and Dana had to order the troops to be withdrawn for the time being, and the battle would be resumed in the afternoon.

The slaves were driven out by the Rouran soldiers and locked up in the camp.

Lu Xuanbo was holding a wooden stick and crutches, his eyes kept observing the slaves and Rouran guards around him, he suddenly raised his leg and kicked a stone on the ground, and the stone "swished" and shot a Rouran soldier.

"Oops!" The Rouran soldier screamed in pain, and immediately pulled out his scimitar and glanced at the surrounding slaves with fierce eyes, shouting: "Who? Who did this to you? ”
