However, it is said that Xuzhou is different from Bingzhou, Yizhou and Guanzhong, which have natural dangers to defend, and it is far inferior to Luoyang, which is known as "in the world", which is surrounded by Xiongguan, and there is no danger to defend at all. What's more deadly is that Xuzhou has a large population, developed roads, and is a real place of four wars, unless each city is guarded by male soldiers, otherwise people can bypass the heavily guarded city and attack the weak defense.

Cao Ying is like this, all the way to attack the city and plunder the land, like a bamboo, it only took five days to take Xiaopei, Fengcheng and other cities into the bag. But whoever gets the city has to be slaughtered on a large scale, in the name of revenge for the father, in fact, it is to plunder the material, especially the local large households, almost no one is spared!

On the seventh day, Cao Ying led Xiahou Xuan, Xiahou Yuan, Cao Ren and other soldiers to Pengcheng City, the seat of Xuzhou Governance. Tao Qian had no choice but to lead troops out of the city to greet him. Looking from afar, I saw that Cao Jun's military appearance was neat, morale was high, like frost and snow, and the Chinese army erected two white flags, and the words "revenge and hatred" were written in a big book.

When the army and horses formed a formation, Cao Ying rode out of the battle, dressed in a vegetarian shirt, and scolded with a whip: "Tao Qian's old thief came to his death quickly, I have no grudge against you, and the old thief dares to send someone to rob and kill my father?" If this revenge is not avenged, I, Cao Mengdeyan, can stand in heaven and earth with my face! ”。

Tao Qian also came out of the door, and bowed to Shi Li and said: "Qian originally wanted to set up a banquet to entertain Cao Gong, so he asked Zhang Min to invite him." I don't want that thief to change his heart, so he has this matter, but he doesn't do it because of Tao Qian, and I hope that Ming will investigate it. ”

Cao Ying scolded: "The old puppet killed my father, and he still dares to talk nonsense!" Who can capture the thief alive? Xiahoudun responded and shot straight in front of the two armies with an iron spear. Tao Qian was shocked and hurriedly turned his horse back to his own position.

"Don't panic, Cao Bao is here!" Cao Bao jumped on his horse with a spear and came to meet Xiahoudun. The two horses intersected less than 20 times, Cao Bao was defeated and retreated, Cao Jun took advantage of the situation to cover up, beheaded more than 1,000 people, and chased to the side of the drawbridge and was shot back by the archers.

Tao Qian was defeated and returned to the city, so he did not dare to fight again, and waited for reinforcements according to the city. Most of these soldiers under him are newly recruited soldiers, which can also be said to be old soldiers, and they may not be enough to fight, but it is not a big problem to defend the city. In addition, the Cao army wantonly slaughtered the people of Xuzhou, and the city was in danger of the people, for fear that the city would be damaged by the Cao army, so many people volunteered to help defend the city.

Cao Ying couldn't find a large siege tool for a while, and he failed to attack several times, but lost 3,000 men and horses. At the moment, he discussed with Xun Yu, Xi Zhicai and others in the army, and decided to carry out the tactics of encircling the point to send reinforcements, personally leading 40,000 troops to surround Pengcheng, and at the same time sending Cao Ren, Yu Ban, Gao Lan, and Cao Hong to lead 10,000 troops each to Huai'an, Xiapi, and the East China Sea to loot and slaughter, and the whole Xuzhou was in chaos.

However, it is said that this Jiujiang is too guarded by the border and is also a well-known person, and he has a good relationship with Tao Qian. A year ago, Tao Qian personally acted as a matchmaker and introduced Huanrui, known as the first beauty in Pengcheng, to Bian Rang as a concubine. Therefore, as soon as Bian Rang received Tao Ying's letter, he immediately set off and led 5,000 troops to Pengcheng.

Cao Ying knew that Bian Rang came to be a lobbyist, and 5,000 soldiers and horses were insignificant to him, and then thought of the name of Bian Rang's beautiful concubine Huanrui, and immediately thought about it, and ordered Xiahou to lead the army to greet him, leading Li Dian and Lu Qian to ambush on the flank, and sitting around the Chinese army camp by himself.

Poor Bian Rang thought that Cao Ying would turn his face when he said it, and he didn't even give him a chance to speak, so he was caught off guard by Xiahoudun and retreated. In the middle of the rush, Li Dian and Lu Qian led the army to kill from the flank, but there was no way to escape, and they were stabbed under the horse by Xiahoudun with a shot and died tragically. Cao Ying was unforgiving, and immediately ordered the three of them to rush to Jiujiang to plunder, while the family was slaughtered, only Huanrui was taken down by Li Dian and brought back to the Pengcheng camp.

Cao Ying saw that Huanrui was twenty-eight years old, with an extraordinary appearance and a big lust, so he immediately accepted her as a concubine and ordered someone to send it back to the base camp of Zhencheng in Yanzhou without mentioning it. But he said that the front foot had just killed Bian Rang, and Chen Gong had a visit on the back foot. Cao Ying knew that Chen Gong and Tao Qian had a good relationship, and he must be a lobbyist here, and he couldn't kill the old favor if he didn't see it, after all, Chen Gong was also his savior, so he had to ask him to meet in the account.

After the greetings, Chen Gong hugged his fists and said: "I heard that Cao Gong came to Xuzhou with a large army to repay his father's revenge, and he wanted to kill the people wherever he went. The murder of his father is Zhang Min's evil, not a crime of humility. And what enmity do the common people of the state and county have against the Ming Gong? Cao Gong indulged in and brutalized the people, wasn't he afraid of causing public anger? ”

Cao Ying disagreed: "My father was killed in Xuzhou, if I can't avenge the killing of my father, I am a son of man in vain, and if you want to blame, you can blame Tao Qian for not being strict under his control." ”

Chen Gong shook his head and said, "Why did Gong Cao say such deceitful words? Since ancient times, the princes have all put buying the hearts of the people in the first place, so how can they slaughter the people? Cao Gong just wants to plunder the materials, and in the name of avenging your father, you have gone perverse and poisoned the living beings, won't you kill yourself? Although the world is chaotic, there is still order and rules. ”

Cao Ying suddenly felt unhappy, and said in a deep voice: "I'd rather bear the people of the world than the people of the world bear me!" I will act with a purpose, and I need not say much. ”

Chen Gong's face was extremely ugly, and he said loudly: "In vain, I still think you are a hero in the world, but I didn't expect it to be a crazy villain, as the saying goes: People are doing, the sky is watching, there are gods three feet above your head, and if you do unrighteous deeds, you will be punished like a thief!" ”

Cao Ying was furious, drew his sword and shouted: "You abandoned me in the past, and now you will see you again?" Tao Qian's old thief killed my family, and vowed to pluck his heart to snow my hatred. If he loves his people like a son, and he should bind himself to ask for sin, why should he resist stubbornly? You should have killed him if you were disrespectful, but you should have spared your life for the time being! After that, he shouted, "Someone! Give this person to me and beat him out! ”

Chen Gong was driven out, embarrassed, and even more angry in his heart, looking up to the sky and sighing: "I don't have the face to see Tao Qianye!" Ru Cao Mengde is not benevolent, don't blame me for Chen Gong's injustice! "After that, galloped to his friend Chen Liutai, and Zhang Miao went.

However, it was said that Ma Chao was developing science and technology in Yecheng, and at the same time passed on the knowledge of physics, chemistry and mathematics to Ma Jun and Kong Ming from shallow to deep. But there are still many problems, such as the knowledge he has learned has special units, such as one second, one meter, one millimeter, one gram, and even acceleration, impulse, velocity and other units, which are not understandable to the ancients. No matter how high Ma Jun and Kong Ming's IQ is, it will take a certain amount of time to accept and digest.

These alone are easy to do, and it is not difficult to understand slowly to explain, the key is that Ma Chao can't determine how long it is a second, how much something is a kilogram, and how long the distance is a meter. Later generations had extremely strict regulations on one second, one meter and even one gram, such as: one second is one third of the average solar year 31,556,925.9747, and one meter is the length of light propagating in a vacuum during the duration of "1/299,792,458 second". If you make up an approximate number, then in practical application, many physical formulas will have a huge error, which can be described as a millimeter difference, and the error is thousands of miles!

Ma Chao had a headache for this, and thought hard to no avail, this time, the three of them were studying the problem of making steel balls with the chief blacksmith Li Tie, and fooled the soldiers to report: Xuzhou Thorn Shi Taoqian sent someone to visit! (To be continued.) )
