This incident was really unexpected by Liu Ping.

In fact, Liu Ping has not been idle recently, he has been gathering skilled craftsmen recently to make the trebuchet and Zhuge repeater transformed by the great inventor Ma Jun.

But seeing that these two things have not been used yet, the situation in Guandu has become tense.

"Yuan Shao's cavalry is as many as 8,000? This is indeed a bit tricky," Liu Ping couldn't help but gasp when he saw this number.

Cao Hong sighed and said: "We still have 4,000 cavalry under our command, and Yuan Shao occupies the land of the four states, which can be described as wealthy.

Moreover, the annexed states under his control border the steppes, and it is much more convenient to buy horses than us, and it is not surprising that there are 8,000 cavalry. ”

"In two days, all the Yuan troops will cross the Yellow River," Cao Ang said with a tense face, "Father's cavalry must not be a high-ranking opponent, how can this be good?" ”

Even if Cao's tiger and leopard cavalry is the elite of the elite, the cavalry of the Yuan army is obviously not vegetarian, and it is twice as large as the cavalry of the Cao army.

In terms of cavalry, Cao's army was still in a weak position.

The three of them discussed for a long time, but in the end, they were only in a hurry, and they didn't come up with the slightest way to delay Yuan Jun.

Liu Ping seemed to have something in his head, but he couldn't say it when it came to his mouth.

When he returned to the mansion, it was almost noon, and he had just sat down in the study when he saw Sanqige, dressed in grassland dress, come in with a tea bowl.

Since the last time the full pet made trouble, Sanqige has moved into Liu's mansion to live.

"Over the years, how many horses have you sold to Yuan Shao on the grassland?" Liu Ping picked up the tea bowl, took a sip, and asked casually.

"I don't know," Sankig shook his head with wide, watery eyes, "you can ask my brother about these things, he knows better, I'll call him." ”

Saying that, without waiting for Liu Ping's consent, Sanqige ran out, and after a while, he came in with Butu.

"Master, listen to Sanqige, are you asking about Yuan Shao's war horse?"

Butu respectfully performed a grassland salute, he was already grateful for Liu Ping's rescue and the grace of his support, and only thought about when he could repay Liu Ping's meritorious service.

"The best horses in the grassland are in the hands of Qubei, as far as I know, there are not too many who are sold to Yuan Shao, but there are many that are sold to Gongsun Zhan.

Yuan Shao's horses, except for the horses we exchanged for him at the beginning, which were bought, the rest were probably robbed of Gongsun Zhan. ”

Hearing this, Liu Ping's eyes suddenly lit up, and the trick that had been troubled for a long time suddenly figured it out, and he quickly stood up and said: "I remember when I was in the grassland, you can make the horse startle, is there any way to do it now?" ”

The Yuan army is powerful, it is powerful in the cavalry, if Butu can be concocted in the same way, like in the grassland, the Yuan army's horses are shocked, then what is Gao Ran afraid of?

"When grazing horses on the grassland, the horn is generally used to give orders to the horses," said Buttu, who said eloquently, "and each of the horns made by the family has its own habits, and the sound of blowing has nuances."

These differences are difficult for our human ears to hear, but the horses can instantly distinguish which horn sound is from their own family.

So even if the horses are mixed up on the grassland, it's fine, just take out their own horns and blow them, and the horses will naturally separate. ”

"You mean, if you want to scare a horse, you have to have the horn of the horse seller?" Liu Ping asked.

"Exactly," Butu nodded, and then took out a horn horn more than a foot long from his bosom: "At the beginning, the slave maid brought one with her when she left in order to raise horses. ”

Only they knew that the horses that Liu Ping bought at the beginning were good horses that went to Beibei after the contract, and those horses were all raised by Butu, so Butu also brought the horns used by the royal horse.

Liu Ping was suddenly overjoyed, took the horn and looked at it over and over: "In this way, this horn can drive all the horses that are sold to the low?" ”

Although Yuan Shao's horses were robbed of Gongsun Zhan, they were all sold by the humble in the end, so they could naturally be driven by the horns of the humble ones.

Unexpectedly, Butu shook his head and said: "This can only be tried, in fact, the horses have been sold for a long time, and after many years of Han breeding, after a few years, they will forget the original horn sound."

How many horses this trumpet can drive, the slave and maid dare not guarantee. ”

"Horses are so forgetful!" Liu Ping opened his mouth wide, as if he had been splashed with a basin of cold water.

The good idea I had just thought of was shattered again.

"I don't dare to guarantee the horses who go to the lowly, but ......" Butu said with a wink, "The horses we exchanged for Yuan Xi Duolan's department must still be half alive."

Those horses have just left the grassland for only a year, and as long as we have the horns of the Dolan Department, the slaves and maids dare to pack tickets, and each one of them can be driven. ”

"How can you go to Dolan to ask for a horn, how can you ......" Liu Ping said listlessly, and suddenly looked at Butu with a shocked expression: "Wait, do you also have a horn number in Dolan?" ”

"Thanks to the master, the slave's wife is the daughter of the Dolan patriarch, and there happened to be such a number in her dowry."

Buttu said triumphantly.

"Really?" Liu Ping's eyes lit up again in an instant, thinking that it seemed that he still had to plant more flowers and fewer thorns, and inadvertently fulfilled the marriage between Butu and the daughter of the Dolan patriarch, and they could help so much at the critical moment.

"Of the eight thousand war horses of the Yuan army, at least fifteen hundred are from the Duolan tribe," Liu Ping muttered to himself, "If the remaining six thousand five hundred horses can be driven by half, then Gao Ran's cavalry will be wasted......

At this time, a slave and maid suddenly came in and reported: "The master of the Qiqi family, the eldest prince is invited." ”

"Good!" Liu Ping patted Butu's shoulder and said with relief: "If you can solve this Yuan army cavalry this time, I will definitely ask for credit for you at that time." ”

"It is a great honor for a slave to be able to serve his master, and a slave and maid do not need any credit."

"Well, if you succeed, the credit will naturally be yours, but ...... Since you are not sure about the horses in the past, don't tell anyone about this until you succeed. ”

Liu Ping is such a character, if he is not sure, he will never take care of everything, he would rather do it first and then talk about it.

"Do as your master commands." Buttu agreed.

Liu Ping hurriedly returned to the study of Sikong Mansion, if it wasn't for an urgent matter, Cao Ang would never have just let him go, and then sent someone to call him back.

Sure enough, Cao Ang's expression was even more solemn than just now, and he walked around anxiously.

At this time, it happened that Cao Hong also stepped in from behind, and said hurriedly: "Ang'er, what happened?" ”

"The letter just sent from Guandu," Cao Ang's hand holding the letter trembled slightly: "My father's headache has signs of attack, and I am afraid that I will not be able to take command in person, so I transferred my uncle to return to Guandu and temporarily take command of the battle in place of my father." ”

At this time, among the brothers on the front line, Cao Chun is too young, Xiahou Yuan is a brave husband, and the most suitable one is Cao Hong.

Now that the rear has gradually smoothed Liu Ping, there is no need for Cao Hong to sit in Xudu.

"The eldest brother's headache must have been anxious by Gao Ran's cavalry," Cao Hong sighed.

"Uncle will definitely succeed in this battle even if he goes," Liu Ping said.
