The Donghu army withdrew from the Great Wall, and Situr looked in the direction of Shangjun from afar, always feeling that something was wrong.

Late at night, Situr still had no intention of sleeping.

Commander Balmon came over and asked, "Strategist, why don't you sleep yet?"

Situr shook his head and said, "I always feel that there is a problem with the Qin army's reinforcements, but I just can't understand what is strange about them."

"Don't think about it, the smoke and dust are so big, you can only see their cavalry and generals, since you can't see their situation clearly, and you can't inquire about their information, it's useless to be entangled." Balmon said.

"Smoke and dust, general!" Situr's eyes suddenly widened, and he woke up in shock: "Oops, suspicious strategy."

Balmont asked, "What's wrong?"

Situr shook his head and sighed: "Alas, we have lost the opportunity to annihilate the enemy army and capture the Su."

The general flag is a flag used to show identity or command the army, so it is only planted in the general's chariot or chariot.

When a country's army goes out, the whole army hangs the flag representing the country, so the Qin army should hang the Qin-character banner, not the Chu character.

The smoke and dust in the sky were used to block their line of sight, and Situr guessed that the Qin army deliberately made the smoke and dust billow, just to disrupt their vision and prevent them from seeing how many soldiers and horses there were.

From a distance, the smoke and dust are flying, revealing many flags, which makes people mistakenly think that there are 200,000 troops to reinforce and tempt them, exactly the same as Sun Tzu's Art of War.

If it was the Qin army that came to reinforce him, he might see through the Qin general's plan.

But the reinforcement commander was Chu Yun, but he had to be cautious, after all, Chu Yun's fame was too great, and when they saw the word Chu, they were shocked by Chu Yun's prestige, so Situr didn't see this layer.

"Chu Yun is worthy of being the number one thinker in Great Qin, and he is really a feared figure." Situr sighed.

Chu Yun was so famous, although many people in the empire were hostile to him, they had to admire Chu Yun's resourcefulness and call him the wisest person in Great Qin.

Meng Tian and Fusu led the Meng family army to join Chu Yun.

"General Chu, I finally looked forward to you." Fusu said excitedly.

Chu Yun said indifferently: "Childe is polite, Chu Yun is an imperial general, and his responsibilities are in his body."

"General Chu, fortunately." Meng Tian said.

More than 100,000 people of the Meng family have been guarding Beijun, they have never seen Chu Yun, they have only heard rumors about him, and now when they see the real person, they all look at him with curious eyes.

Chu Yun said: "I've seen General Meng."

They quickly returned to Shangjun, and Meng Tian ordered the Meng army to rearrange and arrange an additional line of defense on the Great Wall.

Fengtian carried the emperor, and said: Chu Yun is loyal and courageous, loyal to the empire, and specially placed the general, as the deputy general of General Meng Tian, leading 3,000 iron cavalry to the north of the Great Wall, relieving the Su and General Meng Tian's difficulties, Qin this!

A middle-aged eunuch read the decree with a soft voice.

"Three thousand iron cavalry!?" Fusu and Meng Tian looked at each other and were quite surprised.

No wonder they looked at the small number of reinforcements, there was no grand spectacle of 200,000 at all, it turned out that there were only 3,000 iron cavalry.

"The dust is high and sharp, and the car comes; Those who are humble and broad come in vain; Those who are scattered and attained, Qiao Cai is also; Few and those who come and go, the battalion army also. Meng Tian woke up.

They saw that each war horse was dragging a broom and planting several flags, and they understood why Chu Yun could lead three thousand iron cavalry to make such a movement.

The Hu people were besieged in the city, and they saw hope and reinforcements were coming, so they couldn't find out how many reinforcements were coming.

"General Chu is really proficient in the art of war and can perceive people's hearts, and when the enemy finds out, it will be too late, and he will definitely be angry." Meng Tian praised.

Both sides felt that Chu Yun was the commander of an army of 200,000, but they didn't expect him to only bring 3,000 iron cavalry.

"As far as I know, the Hu military division Situr is also a person who is familiar with the art of war, why can't he detect that General Chu is using suspicious tactics?" Fusu said curiously.

Meng Tian said with a smile: "Childe doesn't know, the number of flags and the words on them play an important role."

"What's the explanation?" Fusu wondered.

"Countless generals are swaying, or are they generals surnamed Chu, who will Gongzi think of first?" Meng Tian said.

"Of course it's General Chu Yun!" Fusu Road.

Meng Tian nodded and said, "The Hu people have the information of my Great Qin's generals in the past twenty years, so they must have General Chu, so when they see the Chu character general banner, they will also think of General Chu Yun first."

"General Chu broke through the Baiyue Kingdom and became famous in one battle, and his name is enough to deter the Hu military division Situr, so the first thing Situr considered was not the number of imperial soldiers, but General Chu."

Fusu said: "I understand, after the enemy army saw the banner of General Chu, they couldn't distinguish between the virtual and the real, or that they had shifted their center of gravity, and the battlefield was changing rapidly, and they couldn't see the situation of the reinforcements clearly, so they mistakenly thought that it was really a 200,000 army, so they could only withdraw from the Great Wall to reorganize their troops."

The Hu people are good at grassland warfare, and if they leave the grassland, their combat power will become weaker, so in the face of more than 300,000 Mengjia troops, they can only withdraw from the Great Wall and use the best tactics to confront the Qin army.

"No wonder General Chu asked us to make so many flags and buy a lot of brooms, it turns out that there is so much knowledge, I am an old pawn." Dianchou said loudly.

"If you can imagine it, it's not a pawn, then you are General Chu." Xue Qing teased.

"Haha......"

The generals looked at the ugly and their faces turned red, and they immediately burst out laughing.

"Please also ask General Meng to reorganize the army, and I will wait for General Meng's instructions." Chu Yundao.

Meng Tian waved his hand and said: "I have been holding on to Changjun for more than 20 days, and I have hardly slept well, I must have a good rest today, and the army will be handed over to you, I believe that General Chu will not let me down."

"Soldiers of the Mengjia Army, are you willing to listen to General Chu's orders and let him lead you to break through the enemy slaves and return to the field?" Meng Tian shouted.

"Yes!" Meng Jiajun shouted in unison.

Chu Yun's prestige has long spread in the empire, he once led 50,000 Mengjia troops to conquer Baiyue Kingdom, and he loves soldiers like sons, so if there are any Mengjia soldiers, they will not reject him.

They also miss their hometown and want to be reunited with their families as soon as possible.

Meng Tian handed over the Meng family army to Chu Yun, and he could see that although Chu Yun was a deputy general, the king of Qin wanted Chu Yun to take the Meng family army to defeat the Hu people.

But Meng Tian is the favorite minister of King Qin, and it is impossible for Meng Tian to hand over his military power, and being able to be Meng Tian's deputy general is already reused, so Meng Tian can only give an edict and does not need to hand over the tiger talisman.

"Okay, since the brothers can afford me, I will first rectify it to prevent the Hu people from going south." Chu Yundao.

He first changed the guard post and mobilized 3,000 iron cavalry to serve as a post, so that the soldiers who had been fighting for more than 20 days in Dongjun could rest.

A series of measures were immediately taken to let the soldiers strictly guard the Great Wall.

Chu Yun took 3,000 iron cavalry to scare off the 300,000 Hu army, Meng Tian admired his resourcefulness very much, so he was very relieved that Chu Yun could do a good job.
