Cao Pi didn't even enter Changyi, so he let the envoy camp settle down in the military camp, because this military camp could replenish arrows, and it could also allow the group of gods and envoy camp boys who only carried ring-headed knives to take a good spear and go out to chase down the deserters.

Liu Hong is a very responsible Taishou, he also has a very detailed topographic map of Shanyang County, and he drew it himself, when he took out this map, he drew a few circles with a rabbit pen, pointed out that Shanyang County can pass through Qingzhou several passages, and also depicted the topography of these passages clearly, such as where is a mountain road, is it a waterway, or a gallop road, such as which road a few people set up a deer antler fence with a bow and arrow can be a master, which road needs cavalry to cruise, Which road is the dense forest where fierce beasts are entrenched, and there is no need to guard it, and the old man Liu Hong can say it clearly.

Cao Pi was once again impressed by this sage, and after expressing his respect for him, Cao Pi began to deploy the Divine Envoy Battalion to guard the various obstacles leading to Qingzhou in Shanyang County, and at the same time let two ten-person teams cooperate with the soldiers of Shanyang Prefecture and the township to arrest people. Lu Lingqi followed the ten-person team, and he thought that the rout would not be able to reach the border of Shanyang County, because Qunhe and Xiangyong would inevitably arrest this group of people under heavy rewards.

But Cao Pi didn't think so, those who could run here from Guandu were all old deserters who had crossed the state and county, and they had a lot of experience in escaping, and the aimless capture was not effective, but blocking their retreat, when they tried a few escape routes without success, their psychological defense line naturally collapsed, and they could easily capture them.

As for Cao Pi, he discussed the number with Liu Hong in the military tun, in fact, Cao Pi did not discuss with Liu Hong, but wanted to help Liu Hong improve his abacus, after lunch on this day, Cao Pi asked Liu Hong about Liu Hong's "positive and negative number abacus", Liu Hong explained to him. Cao Pi knew that this "positive and negative number abacus" was just a calculation method evolved on the basis of the calculation, and it was not close to the abacus of later generations, so Cao Pi directly drew an abacus on Zuo Bo paper, and was about to tell Liu Hong how to mark a hundred million digits on it, but he saw Liu Hong snatch Zuo Bo paper over, his hands tightly pulled the two ends of the paper, his eyes stared at the abacus, and muttered to himself.

Listen carefully, this guy actually multiplied the trick for another year, in fact, the multiplication trick appeared in the book "Xunzi", which can be said to be the unique mathematical wisdom of the Chinese, in the late Han Dynasty, this kind of wisdom that later generations of foreigners think is so powerful that many people actually will, let alone Liu Hong, a mathematical master.

After watching it for a while, Liu Hong laughed, maybe he was old, he coughed for a while, and the two children who were waiting for him immediately stepped forward to stroke his back, Liu Hong slowed down his breath and said urgently: "Go, go, go!" Go and call Xu Gonghe to the old man! If he doesn't come, he will repent for the rest of his life! A little boy went immediately.

Liu Hong spread the Zuo Bo paper on the case, and used a rabbit pen to mark out a number of ten hundred million digits on the middle beam of the two beads and five beads, and he was uninspired, and then he began to mumble to himself, Cao Pi knew that this guy probably wanted to use a simpler method to replace the arithmetic chip for a long time, but it was difficult to invent a new perfect arithmetic tool, and it was not until the Ming Dynasty that the abacus completely replaced the arithmetic chip.

Now Cao Pi has given Liu Hong a framework, with Liu Hong's knowledge, how to play the role of this thing does not need to be taught by others at all, otherwise he will not be able to become a "saint". At this time, Cao Zhen called outside the house, and Cao Pi immediately walked out, Liu Hong still held the abacus on the paper, and he didn't feel that anyone was leaving at all.

When he went out of the house, he saw Cao Zhen riding a horse, and there were four disciples of the divine envoy camp behind him, they were holding a rope in their hands, and behind the rope were a group of people, seven or eight more, five or six less, all men, these people were covered with dust and dust, and their faces were yellow and thin.

I only heard Cao Zhen say: "This is the rout caught on the gallop road to Qingzhou, and the younger brother has already let another group of people take it, these guys and the younger brother have been guarding all night, and they have come back to rest and rest." ”

Cao Pi nodded and said, "Take these people to the Juntuntian Officer, give them a bite to eat first, and then wait for someone to receive them." ”

Cao Zhen immediately ordered that it was a knight of the divine envoy camp, dismounted and came to Cao Pi, drank a sip of water, glanced at the room behind Cao Pi and asked, "As soon as my brother came, I ran into the house with Liu Taishou, and my brother has learned to calculate in the past few days?" ”

Cao Pi waved his hand and smiled: "What kind of calendar, this kind of thing is too difficult, and I can't do it for my brother." ”

Cao Zhen smacked his tongue and said, "Then why didn't my brother go to chase down the rout with his sons?" ”

Cao Pi smiled and didn't speak, thinking that Lao Tzu was helping mankind to progress, but when he told Cao Zhen, he was afraid that the other party would not understand.

At this moment, a commotion came from outside the military tun, the location of the two of them was still a few hundred meters away from the edge of the military tun, the sound could be transmitted here obviously very loud, Cao Pi frowned, Cao Zhen cheered up and shouted: "What's the matter?" Could it be that there is still a rout to storm the army can't be reached? ”

At this time, a guard of the military camp helped a blood-stained man in linen and stepped forward and said, "Childe, the county soldiers and Xiangyong sent out by the Taishou have been scattered by the rout!" This person is the county lieutenant of JX County. ”

The county lieutenant is under the county order, in charge of the security of a county, Cao Pi was stunned when he heard this, it stands to reason that it is impossible to disperse the county soldiers and township Yong in this situation, without waiting for him to speak, Cao Zhen "hey" stepped forward and pulled up the county lieutenant who was covered in blood, looked at it twice and drank: "You are injured by blunt weapons all over your body, and the person who beat you has no weapons at all, why was it washed away?" ”

The county lieutenant trembled and said, "The thieves wrapped the stones in strips of cloth and threw them at us with micro-ends in their hands, hundreds of them! The stone wrapped in the cloth was like rain, and we we"

Cao Zhen pushed the county lieutenant to the ground and scolded: "Useless person! ”

Cao Pi thought that Lu Lingqi and the twenty ten-man teams were also in the team that was chasing and suppressing the rout, so he asked, "Who is in command of the county soldiers and the township soldiers?" ”

The guard replied, "Commanded by Captain Li of Shanyang County." ”

The man who fell to the ground groaned: "Captain Li has been stoned to death"

Cao Zhen kicked the man and drank: "Shut up! Came to Cao Pi's side and whispered: "Wrap the stone in a cloth and throw it out in a few circles on the top of your head, that is the method used by the Hu people in the north, but the cloth strip is a rope, and a stone will be worn on the rope or a stone is called a flying stone Suo There are Hu people in the people?" ”

Cao Pi said: "Not only the Hu people, I am afraid that there are Hu people who are the commanders of the army, how can ordinary people have the ability to let hundreds of people listen to him when they escape" and then said to the guard: "Give us six people, one of whom is equipped with two arrows and arrows!" Then bring me my horse. ”
