Shi Xun really wanted to left, because of the success of Tuntian, Cao Cao's strength at this time was much stronger than when he attacked Xuzhou in the original history (it should be in the next year), and the situation of retreating troops was not as dangerous as he expected.

Originally, in history, Cao Cao crusaded against Xuzhou twice, and only used half of Yanzhou's soldiers and horses, and most of them were Qingzhou soldiers who were loosely disciplined but could endure hardships - no way, there was not enough food, and if you brought more soldiers, you would go bankrupt - and the remaining half were all handed over to Zhang Miao and Chen Gong, so when Lu Bu entered Yan, his strength quickly swelled to surpass Cao Cao. Cao Cao fought a big battle with him in Puyang, although he barely repelled the enemy army and entered Juancheng, the total strength dropped to more than 10,000.

But this time is different, Cao Cao plans to defeat Yuan Shu in one fell swoop, even if he can't conquer Shouchun and annihilate him, he has to completely drive this bastard out of Yuzhou, plus the flanks are worry-free, so he has done his best to make the elite in the state - even the Qingzhou soldiers he brought are the ones who can talk to them about organizational discipline when they are full. Originally, there were not many soldiers and horses left for Zhang Miao and Chen Gong, and most of them were old, weak, sick and disabled or the guards of various cities. Although the anti-flag was in one fell swoop, except for Juan and Fan Ercheng, the entire Yanzhou was "changed by the river and the mountains and the party changed", but Lu Bu and Chen Gong even brought many private soldiers and slaves of large households to the battlefield, and they were not half of Cao Cao's strength.

Cao Cao's Yuan Shu is still strong, if you really want to study it, he plus his ally Runan Yellow Turban, he is much stronger than Lu Bu behind Cao Cao. But Yuan Shu is a waste snack without any enterprising spirit, and Cao Cao wants to withdraw his troops before the battle, so he is not embarrassed at all.

So after getting the news of the rebellion in Yanzhou, Cao Cao immediately asked Cao Hong and other generals to break away from contact with the Yellow Turban in Runan and retreat to Nanton, Xinyang and other counties in the north of Runan County. The route of Cao's army was from Runan through Chen and Liang into Jiyin - Chen and Liang both belonged to the Yuzhou Thorn History Department, at this time Guo Gong had become Cao Cao's puppet, and the cities in the two countries were in line with local protectionism, and were not affected by the Yanzhou scholars' riots, and were still in a state of semi-independence and semi-attached to Cao, so not only did not obstruct it, but instead sent grain, grass and materials to labor the army.

Because for the local scholars, Cao Cao is not terrible, the Runan Yellow Turban is the enemy, if Cao Cao falls, the Runan Yellow Turban, which is supported by Yuan Shu, may go north to harass him, which is the class contradiction related to life and death! We and Cao Cao are just the people after all...... There are contradictions within the landlord class.

The vanguard of the Cao army, Xiahoudun, had more than 6,000 people, two percent of whom were cavalry, and they traveled day and night, wanting to attack Dingtao before Lu Bu and hold the Jishui defense line. But when he got to the single father and the Ji clan to take a look, it was over, it turned out that Lu Bu had already set up a camp here and built a defensive line.

So the generals were summoned for counseling. Sima Shihuan suggested: "I see that although the enemy army is numerous, the array is not in order, and the camp is not finished, so I can take advantage of this opportunity to attack its weak position and frustrate its front." If the move is not delayed, when Cao Gong arrives, I am afraid that his camp has been set up and the formation has been completed, and it will be difficult to overcome it at that time. ”

Xiahoudun felt that what he said was reasonable, so he spotted a weak point in the defense line of Lu Bu's army, and suddenly launched a fierce charge. Originally, he just wanted to fight hard, mobilize the rest of Lu Bu's troops to come for reinforcements, and then he would retreat and harass other places, but he didn't expect that as soon as he broke into the enemy formation, he heard a series of drums, and countless flags came straight over. Xiahoudun secretly screamed that it was not good, and he fell for Chen Gong's trick - he didn't believe that Lu Bu could be so smart.

At the moment, he hurriedly shouted "withdraw", and ordered Shi Lian to lead the department first, and he was the queen of the palace. Xiahoudun is also a fierce general of Cao Ying, with a long lance in his hand, with the courage of ten thousand people, and now under the cover of hundreds of personal guards, he dances like a lance, kills several soldiers in a row, and fights and retreats.

When he was retreating, he suddenly heard a shout from the opponent's array: "Gao Shun in the clouds is here!" Immediately, I saw more than 200 horsemen surrounded by a general, separated from the columns, and galloped in front of me like a gallop. Those cavalrymen were so brave, and as soon as they saw each other, Xiahou Chen's troops were stabbed by more than a dozen. Xiahoudun's eyes were cracked, and he went straight to Gao Shun - if he can defeat this general, he may have a glimmer of life, otherwise I am afraid that I may be able to escape alone, and none of these parts under my command will be able to go back!

Gao Shun slapped the horse and twisted the lance, and made a move with Xiahoudun, and both parties were secretly shocked in their hearts - this person is so good! But Gao Shun was just an ordinary shock, Xiahou was so shocked that even his liver trembled, and he said in his heart that it was not easy to defeat this person, could it be that the pro-guard tribe I had worked so hard to select and cultivate, would all die here today?! And...... Maybe even you can't escape the word "death"!

was frightened, and heard a loud shout from Zuo Jin: "Long Dao retreat, wait for a certain person to come and capture him!" "You don't need to look at this meow to know that Lu Bu is here! Xiahoudun is discouraged at the moment, and after his heart is finished, he will definitely die today. Okay, Lao Tzu is fighting with you, killing one is enough, killing two to earn one, Meng De will be able to avenge me sooner or later!

Seeing Gao Shun retreating, Xiahoudun hurriedly concentrated on vigilance, paying attention to Lu Bu at any time, not knowing where Lu Dao would come from. But at this time, I suddenly heard that Lu Bu's formation was like a hundred thunderbolts falling to the ground, and a series of explosions exploded, followed by several fires, rising into the sky!

It had been three or four days since Lu Bu arrived south of Jishui, but the fortifications could not be built, all because of the frequent harassment by Tai Shici's subordinates.

Guo Jia proposed two strategies, and Tai Shici instinctively wanted to make the first strategy and go south to chase Lu Bu. As a general, of course he wants to challenge a powerful enemy and go north to fight Zhang Miao? That Zhang Miao is a god horse thing again? It's just a talk about scribes, and when it comes to fighting, he has a fight with Kong Rong. But Taishi Ziyi has to focus on the overall situation after all, so he asked Xun Yu first, saying I don't know Cheng Li, do you think he can at least block or repel Zhang Miao?

Xun Yu hadn't spoken yet, it was Xun Xian who patted his chest in a big way and guaranteed Cheng Zhongde. I am also one of the five strategists of Cao Ying, alas, and not only strategize, but also really lead the troops into battle, at least to defend a city and a village, the generals who are one or two levels worse than Lu Bu basically can't fight, not to mention the little Zhang Miao?

So Tai Shici decided to go south to chase Lu Bu. He said that he was only going to harass and prevent Lu Bu from building a defensive line, so he must use the elite, the number is not large, three or five thousand people are enough. He also suggested that now that Juancheng is as stable as Mount Tai, he might as well send another army to support Cheng Li, so that he can retreat Zhang Miao as soon as possible.

Xun Yu allocated 4,000 elites to Tai Shici, including all the cavalry in the city, about more than 200 horsemen. At the same time, he sent Xue Yi to lead 3,000 infantry troops to reinforce Cheng Li.

Tai Shi Ci must also be involved in Shi Xun, saying that I am not Cao Ying's official general, and you are Cao Cao's in-laws, with you with you, Xun Yu and them are also at ease, and second, there are many Qingzhou soldiers under his command now, and I have to rely on you to envelop and suppress, so that I can mobilize easily.

Yes Xun really didn't want to go, but he didn't know what Lu Dao was for, he just refused or didn't dare to refuse Tai Shici. Later, I thought about it in private, probably because of the personality charm of the fierce general brother - after all, he is so full of killing and bravery, it seems that he is born to lead others, he has never encountered it seriously in his previous life, and he has seen a few in this life, but he is not too close to Shi Ci to be close to him. He almost pointed at Tai Shici's nose and scolded: "You are the demon star of my life......"

But he insisted on bringing Wu Zhen, Xie Zheng, and two carts full of mysterious goods. Bringing Wu Zhen into battle is to exercise this young man, maybe he can be of great use in the future. As for bringing Xie Zheng and the two truckloads of goods...... Hey, haven't we already researched gunpowder?!

Charcoal, sulfur, saltpeter, there is no shortage in Juancheng, it is Xun Xun who found Xun Yu, so to say that they were all packed and loaded on the road. So when he camped that night, he ordered Xie Zheng, you made all this into gunpowder for me!

Xie Zheng knelt down for Shixun on the spot, saying, "The concubine can't do it...... Well, that's probably what it means. Xie Zheng explained that this smelting is a technical work, not a day or two can be completed, let's just say refining this "gunpowder", although he has basically mastered the formula ratio of the three main ingredients mentioned by Shi Xun, but he also has to add a lot of auxiliary materials, such as pine resin, yellow wax, and so on. Besides, the main ingredient also has to be reprocessed, and the sulfur and saltpeter used for medicine are now sold everywhere, which are not sufficient, but must be purified first, otherwise the power will be greatly reduced, and the gunpowder produced is not necessarily better than ordinary ignition materials, such as grass wormwood and rosin, and it is likely that it will not be able to explode at all.

Third, in order not to suddenly "fly turtles and snakes" during the refining process and injure himself, Xie Zheng pondered and decided to use the "water refining method" in the smelting technique, the probably process is to first melt the raw materials in water, then blend, and then dry and grind after the most grinding - in this way, the only danger can only appear in the grinding process after the most erosion, and the overall insurance coefficient has been more than doubled.

So, master, you are now putting two main materials in front of me, and asking me to make gunpowder for you, I really can't do this!

Shi Xun listened to Xie Zheng's explanation, and was shocked and angry on the spot. I was surprised that I couldn't imagine that it was so troublesome to make a gunpowder, and I thought that I had all the ingredients for charcoal, sulfur, and nitrate, and I could make it by mixing it together; I'm angry that why didn't you tell me before you left the city, I would have known that Lu Dao would be so troublesome, so I wouldn't have brought these two cars out of the way! He was so hated that he pounced on it and gave Xie Zheng two kicks. Xie Zheng was also wronged, and said that when you brought me here, you didn't say that you were going to make gunpowder, and the two truckloads of sulfur and so on were also tightly wrapped and pretended to be mysterious, how could I explain it to you in advance?

The last thing is that Xun had to pat his thigh, forget it, since these two carts of things have been pulled out, it is a waste to throw them away - after all, it is worth a lot of money - let's continue to take it, and when we get to the ground, Tai Shici harassed Lu Bujun in front, and I will supervise you to collect auxiliary materials and refine gunpowder with the rear. If you refine it, I will be rewarded, master, if you can't refine it, hey, hey, hey, thank you, then I will marry Kang Min to you, and change your name to Ma Dayuan!
