Three Kingdoms: The identity of the financial master behind the scenes was exposed by Cao Cao

Cao Cao's spirit was greatly boosted.

The generals also became excited and all looked at Cao Yuan.

Their Royal Highness, the Crown Prince, is as resourceful as a god, and he never fails to make every plan.

This time, His Highness the Crown Prince said that if he had a clever plan to defeat the Black Mountain Army, he would definitely be able to defeat it.

"Prince, if you have any clever ideas, tell me quickly."

Cao Cao couldn't wait to ask.

Cao Yuan took his time and explained his plan.

Cao Cao suddenly realized it and couldn't help laughing and said:"Wonderful, the prince's plan is very good. I will use your plan. Destroyed the Montenegrin Army!"

……

West of Tongguan.

On the avenue.

Countless Black Mountain cavalry are coming towards Guancheng in a steady stream.

On the city.

The soldiers of Xiliang were all in high spirits when they saw such a new force coming for reinforcements.

"I got 40,000 Montenegrin troops to help me for nothing. Cao Cao, let’s see how you can defeat Tongguan!"

Ma Chao looked down at the Black Mountain Army and couldn't help laughing loudly.

Behind him, Pang De and other generals all breathed a sigh of relief and had great fighting spirit.

Zhang Yan, the commander of the Black Mountain Army, entered the city, climbed up the tower, and came to pay homage to Ma Chao.

Ma Chao said to Zhang Yan , naturally praised and comforted him a lot, and personally took Zhang Yan’s hand and returned to the military mansion.

In the main hall, a grand banquet was already arranged.

Ma Chao and Zhang Yan were drinking with great pleasure.

"Your Majesty is kind to me, and His Royal Highness the Crown Prince treats me so kindly. I will go through fire and water for the Qin Dynasty without any hesitation!"

Zhang Yan cupped her hands and expressed her loyalty.

Ma Chao was overjoyed and comforted Zhang Yan.

Zhang Yan was half drunk and said proudly:"Your Highness, our Black Mountain Army has arrived. Your Highness, don't worry. I will cut off the heads of Cao Cao and his son for the sake of the crown prince!"

Fa Zheng, Zhang Song and other advisers saw that he underestimated Cao Cao and Cao Cao so much that they couldn't help but look at each other with a little uneasiness in their eyes.

Ma Chao coughed a few times and said:"Cao Cao is nothing to worry about, but that Cao Yuan is cunning and cunning. General Zhang, you better not underestimate Cao Yuan."

"Our Black Mountain Army has arrived, so what's the use of Cao Yuan being deceitful. Zhang

Yan said disdainfully:"His Royal Highness, just give the order. I am willing to lead the army to fight immediately and destroy Cao Yuan for Your Highness!""

Zhang Yan was arrogant, but Ma Chao was very pleased with his willingness to fight.

However, Ma Chao did not become arrogant and dared to lead his army out of the border to have a showdown with Cao Cao.

He used Zhang Song's strategy , decided to take advantage of their large number of cavalry and sent a large number of light cavalry to rob the Wei army's food and grass.

With an order, 40,000 Black Mountain cavalry came out in full force and detoured towards the Wei army's food road that was hundreds of miles long.

The Black Mountain army was different from the Wei army. Ordinary cavalry.

Ordinary cavalry are only good at fighting on the plains.

The Black Mountain Army has been hiding in the Taihang Mountain Army all year round. Its cavalry can not only fight on the plains, but is also good at fighting in the mountains.

In just one month, the Black Mountain Army has been constantly appearing in the mountains. , launched plunder attacks on the Wei army's food routes again and again.

After successfully robbing the food, the Black Mountain army retreated into the mountains, leaving the Wei army unable to pursue.

Although the Wei state did not lack food and grass, most of the military rations it needed had to depart from Luoyang. Passing Hangu Pass to the west, passing through the narrow Hongnong County, and then arriving at the front line of Tongguan. Such a long and narrow grain road is convenient for the Heishan Army to attack.

Five hundred thousand grains and grass!

In just two months, the Wei Army had Nearly 500,000 grains and grass were burned by the Black Mountain Army.

In order to protect the grain road, Cao Cao also tried to send Chi Ma Yi Cong to protect the grain.

However, the number of Chi Ma Yi Cong was limited after all and could not be defended everywhere.

The Black Mountain Army used With their strength in numbers and their ability to run in mountainous areas, they appeared mysteriously on the front line of Hongnong County and continuously attacked the Wei army's food team. In the depth of winter, the confrontation at Tongguan seemed to be gradually turning into a situation that was unfavorable to Wei.

……

Wei camp, imperial tent

"The day before yesterday, our army's grain and grass in Shaanxi City were robbed by the Black Mountain Army, resulting in a loss of 60,000 dendrobium of grain and grass."

"Before dusk yesterday, our grain team was robbed on the front line of Xin'an, 40,000 pieces of grain and grass were burned, and all the grain protection teams were killed or injured."

Cheng Yu read out an urgent report that the grain team had been robbed.

All the generals gritted their teeth, clenched their fists, and held their breath.

"That's too much!"

"Over the years, we have been the only ones suppressing and fighting against the enemy. How could we be bullied by the enemy in this way?"

Cao Ren cursed angrily.

Taishi Ci also held up his hands and said:"Your Majesty, we cannot allow the Qin army to harass us like this!"

Although the generals were angry, they were helpless.

Who made the Black Mountain Army, different from ordinary cavalry, good at fighting in the mountains.

This made it impossible for Cao Cao to be foolproof no matter how many food protection troops he sent.

"Your Majesty, doesn’t His Royal Highness have a clever plan to defeat the enemy? We must implement it quickly!"

Cao Ren urged with cupped hands.

Cao Cao frowned and looked at his son.

Cao Yuan said unhurriedly:"If you want your strategy to succeed, you must first lead all the Black Mountain Army to one place and defeat them all in one fell swoop. Annihilate them all in one battle!"

"What the prince said makes sense. Cao

Cao nodded repeatedly:"The Black Mountain Army is here and there. We must lead them to one place before they can all be annihilated. Only then can we completely solve the problem of our food and grass being robbed.""

"Having said that, Ma Chao sent Zhang Yan's Black Mountain Army to rob our food route just because he didn't dare to challenge our army for a decisive battle."

"What means can we use to lure the Black Mountain Army out?"

Cao Ren questioned again.

"Your Majesty, we are forcing the city to retreat. Ma Chao is afraid and naturally he does not dare to leave."

"In my opinion, why don't we show weakness and take the initiative to withdraw our troops, so that we can lure Ma Chao's Montenegrin Army out?"

Pang Tong offered a plan

"What Shi Yuan said makes sense."

Guo Jia also said:"Ma Teng is a self-defended thief, but this Ma Chao is ambitious. He will not be satisfied with just guarding Tongguan. If he sees a chance to defeat our army and regain the lost territory, he will definitely be lured out."

The advice of the two advisers swept away the clouds on Cao Cao's face.

"Prince, what do you think? Cao

Yuan nodded slightly:"I think it is feasible, but the only plan is to withdraw the troops immediately, so that the Black Mountain Army can be lured out of Tongguan, gathered together and annihilated!""

"Okay, just as you said! Cao

Cao waved his hand happily:"Pass my decree, the whole army will immediately break out of camp, raise the flag of retreat, and retreat towards Luoyang!""

After giving the order, the 200,000 Wei army officers and soldiers immediately broke out of camp and began to retreat eastward.
