After listening to Guo Jia's analysis, Nan Ye knew that although Yanzhou had the largest population, money and food, it was also the most undesirable. If Nanye hadn't captured Yanzhou after Liu Bei and Sun Quan had taken the annex and Qingzhou, then they could march into Yanzhou from the east and west respectively, and they could also help Nanye in the name of it. In the end, it is very likely that Nan Ye carried the soldiers and horses of Xuchang, Chenliu, and Yecheng, and let Liu Bei and Sun Quan attack the city and pick up the cheap. However, there are no absolutes in the world, on the other hand, if Nan Ye can quickly take Yanzhou, it will indeed take a big advantage.

From the analysis of the current situation, if Nanye's Jiaozhou army bypassed Xuchang and entered Yanzhou, and Liu Bei and Sun Quan divided their troops to invade Bingzhou and Qingzhou, then Cao Pi of Yecheng would get a false message - Xuchang was lost. In this case, as long as Cao Pi was a little timid and weak, he would not dare to let the army leave the city, because once the army left the city and fought with Nanye for a long time, Liu Bei and Sun Quan might enter Yecheng. Therefore, it is more likely that Cao Pi will defend Yecheng, and Nan Ye does not have to worry too much about the reinforcements from Yecheng.

What worries Nan Ye the most is Li Ru in Xuchang, if he enters Yanzhou, Li Ru can completely cut off his back road. The boulders outside the city are a serious obstacle to the siege equipment, but they are of little significance to prevent the soldiers and horses from leaving the city. Now that Nan Ye thinks about it, when Zhuge Liang mentioned that the boulder hindered Cao's army, it was probably just to pave the way for the plan to divide the troops and attack.

Now that the plan has been set and the territory has been divided, there is no point in Nan Ye regretting it, so he asked Guo Jiadao: "The matter has come to this, what should I do?" ”

Guo Jia thought that Nan Ye would complain that he was still clumsy and didn't say anything to remind him just now, but he didn't expect Nan Ye to blame at all, which made Guo Jia very moved. He already had a plan in his heart, so he said to Nan Ye: "It is not difficult for the national teacher to take Yanzhou quickly, he only needs to attack with all his strength." ”

Nan Ye frowned and said: "I'll wait for all three people to go, what if Xuchang Cao Jun cuts off my way back?" ”

Guo Jia said with a smile: "Naturally, it is a false tactic to make the soldiers and horses in the city dare not leave lightly." However, this plan also requires the national teacher to sit here and borrow some things from the king of Guanzhong and the king of Wu......"

When Nan Ye found Liu Bei and Sun Quan to borrow flags, camps, and armor from them, Zhuge Liang and Lu Su guessed that Nan Ye was going to trap Li Ru's soldiers and horses in Xuchang City with a false army. Nan Ye didn't bother with Liu Bei and Sun Quan when they divided the troops, which also made it difficult for them to refuse Nan Ye's request, not to mention that trapping Xuchang Caojun would be beneficial to the three families. So Liu Bei and Sun Quan each lent 10,000 sets of uniforms to Nan Ye, and the camp and banners were also left to Nan Ye.

"Whoosh~Boom~" When the thunderbolt outside the city roared again, the Cao army stationed on the city wall no longer had the panic in the face of the stone bullets at the beginning, but quickly ran down the city wall in turn, hiding behind the wall and hiding. However, there were still a few unlucky Cao soldiers who turned into blood and left on the city wall.

The roar of the thunderbolt did not frighten Li Ru in Xuchang City, but it made him feel very strange. It is said that the boulders all over the ground outside the city have already explained their intentions, and the thunderbolt car has been silent for two days, Li Ru does not understand why the three people still have to do such useless work.

If something goes wrong, it is a demon, and Li Ru really wants to go to the city to see what is going on. However, the boulder flying in the sky made him dispel this idea, and he only ordered the soldiers to go up to the city to take a look. And Li Ru got the reward that there was no change in the three roads.

Li Ru knew that it was impossible to order the soldiers to stay at the head of the city at this time and keep an eye on the three people, so he could only let the soldiers probe again after a while. This time, the soldier really brought back the news, and reported: "The soldiers and horses outside the city are taking the opportunity to carry the boulder outside the city. ”

Hearing the soldier's report, Li Ru smiled slightly and said, "It turned out that I wanted to use the thunderbolt to suppress the bow and crossbow to clean up the boulder, but I didn't want you to wait." After that, Li Ru summoned Cao Zhang and other generals and instructed them to use the thunderbolt cart in the city to shoot to meet the attack. Although the indiscriminate shooting of the thunderbolt was not as accurate as that of a bow and crossbow, it could also pose a threat to the soldiers carrying the boulders outside the city, and Li Ru believed that he must be faster than the speed of the stone removal outside the city.

Nan Ye saw that the thunderbolt cars in the city were also beginning to exert their power, so he ordered Dian Wei and Zhou Cang to inform Liu Bei and Sun Quan that they could withdraw their troops. At this time, the people who controlled the thunderbolt outside the city and cleaned up the boulders were actually Nanye's Jiaozhou soldiers, and Liu Bei and Sun Quan's men and horses had already prepared to withdraw in the camp, and they retreated unconsciously after confusing Li Ru.

Li Ru thought that he had seen through Nan Ye's plan, so he just ordered someone to use a thunderbolt to fight back, but he no longer ventured to the city to check the movement. In this way, I don't know that Liu Bei and Sun Quan's army has retreated, and when the three-way soldiers and horses besiege the city, the plan of the false army has been completed.

After Liu Bei and Sun Quan withdrew their troops, Nan Ye began to prepare for his brigade to leave Xuchang to attack Yanzhou. Without Liu Bei and Sun Quan by his side, Nan Ye ordered his soldiers to transform the thunderbolt outside the city overnight, transforming a generation of thunderbolt cars into simplified thunderbolts. This kind of simplified thunderbolt car later developed by the Jiaozhou Academy of Sciences is not only more powerful and has a longer range, but also uses less materials and is simpler to operate.

The purpose of Nan Ye's transformation of the Thunderbolt was not to siege the city, but to save manpower, so that the firepower could not be reduced after the reduction of troops, and Li Ru would not find a flaw.

Originally, it was enough to have 10,000 soldiers in the simplified thunderbolt car, but just in case, Guo Jia left 30,000 horses for Nan Ye. Among them, 10,000 Jiaozhou troops, 10,000 Fujian armor troops and 10,000 Jiaozhou cavalry, Gao Shun's trap was also left to Nan Ye, so even if Li Ru led troops out of the city, Nan Ye would have the strength to fight. What's more, Nan Ye is surrounded by Dian Wei, Zhou Cang, Zhang Baiqi, Ma Yunluo, Zhu Ronghuabei and a group of guards. And Guo Jia led Zhao Yun, Yang Xiong, Huang Zhong, Huang Xu, and Wei Yan to take Yanzhou.

Nan Ye ordered Dian Wei and Zhou Cang to lead 10,000 soldiers to put on Liu Bei's soldiers and armor to pretend to be Liu Bei's people, Gao Shun and Zhang Baicai led 10,000 soldiers to pretend to be Sun Quan's people, and Nan Ye himself took Ma Yunluo and Hua Bei to guard the camp. What Nan Ye has to do every day is to show his face under the city, so that Cao Jun in the city will know that he is not leaving.

The firepower of the thunderbolt outside the city did not decrease but increased, and Nan Ye, as the commander of the three armies, supervised the battle every day, Li Ru and Cao Jun in the city did not notice that the 300,000 army outside the city had become 30,000, let alone that the smoke had risen in Bingzhou, Yanzhou, and Qingzhou.

However, it was said that Guo Jia and Zhao Yun bypassed Xuchang all the way to the boundary of Yanzhou, and everywhere they went, they all looked at the wind and fell. On the one hand, it was because of the strong strength of the Jiaozhou army, and on the other hand, because the Yanzhou Cao army was mostly gathered in Xuchang, and the counties were rarely prepared, which made Guo Jia go all the way to Chen Liucheng.

Chen Liu's general Zhang was Jing Zhaoyin, and Cao Cao was deeply respected, and Cao Cao died, and Si Li was obtained by Nanye, and Zhang Ji was assigned by Cao Pi to guard Chen Liu. Knowing that Nanye's soldiers and horses had invaded the border, Zhang Ji thought that Xuchang had been lost, and sent someone to inform Cao Pi on the one hand, and gathered Yanzhou soldiers and horses in the city on the other, which was also one of the reasons why Guo Jia was not hindered all the way.

Zhang knew that Chen Liu was the last barrier to Yecheng, and if Chen Liu, Yanzhou would be lost, and Nan Ye, Liu Bei, and Sun Quan would be able to come to Yecheng. So Zhang Ji made up his mind to defend Chen Liu, waiting for reinforcements from Yecheng.

Zhao Yun arrived at the city of Chenliu, and when he saw that the city gate was closed, he called for a battle under the city. Zhang saw Zhao Yun, how dare he go out of the city? Just ordered the arrows to be fired. As soon as Zhao Yun saw that the Cao army at the head of the city was dense and the flag was fluttering, he knew that there were many people in the city. So Zhao Yun ordered the front army to camp and only wait for Guo Jia's brigade to arrive before discussing.

Just when Zhao Yun was camping, a gust of wind suddenly rose, and in an instant, the clouds were thick, and the raindrops the size of beans fell down. As soon as Zhao Yun saw that the heavy rain was coming so quickly, he knew that the team behind him was afraid that he would be drenched, so he hurriedly ordered his soldiers to speed up and set up camp.

When Guo Jia, Huang Zhong, and Wei Yan led the team to arrive, everyone was soaked. Wei Yan complained when he entered the tent: "This ghost weather, why did it suddenly rain." ”

Huang Zhong was old and strong, and he didn't care about the rain, but smiled: "It's cool to rain hard." ”

Guo Jia asked Zhao Yundao while wiping the rain on his body: "Zilong arrived first, what is the situation in the city?" ”

Zhao Yun replied: "The wall of Chenliu is not high, but it is very strong, and there are many soldiers and horses in the city, about tens of thousands, and the guard is Zhang Ji, I am afraid it is not easy to persuade him to surrender." ”

Guo Jia was very satisfied when he saw that Zhao Yun had received so much news and set up the camp, and said, "It's hard work." ”

Zhao Yundao: "Camping and exploring the path is a pioneer duty, and the military advisor does not need to praise it. It's just that I don't have fewer soldiers and horses in the city than I am, so can the military advisor have a clever plan? ”

Without waiting for Guo Jia to speak, Wei Yan said: "Why do you need to break this small city? Build a thunderbolt to destroy its morale first, and then build a ladder to attack it. ”

Guo Jia smiled when he heard this: "Wen Chang's plan is not bad, but it takes a long time to build the equipment, if you want to get Yanzhou quickly, you still need a miracle plan, and I will make a decision after I look at the terrain." ”

The heavy rain fell for a while before it stopped, but the dark clouds in the sky did not disperse, and I did not know when it would rain again. Taking advantage of the rain to stop, Guo Jia led the generals to ride out of the camp on horseback, ascended to a high ground on the edge of the city, and looked at the city and its vicinity. I saw that the Cao army in the city was not stopping, and the estimated number was as much as seventy or eighty thousand, and it was difficult to take advantage of it if it was attacked. Guo Jia saw that the Yanshui on the edge of the city was turbulent and the river was flowing endlessly, so he called the guide officer and asked: "The river here is very urgent, and a rain will not stop here, but it has often rained recently?" ”

The guide said: "In August and September, when autumn falls, there are often heavy rains, and this is the case throughout the year. ”

Guo Jia smiled when he heard this: "I have a plan!" After that, he returned to the camp and ordered the soldiers to cut down wood for boats and pack up rain gear.

Wei Yan asked Guo Jia curiously: "Why do you need to use boats to attack cities on dry land?" ”

Guo Jia said: "Yanzhou is the place where Yu controls the water, and the river often floods. Now that the autumn rain continues, Yanshui will inevitably rise. I have sent people upstream to block the water outlets everywhere, and when the rain and water are heavy, we will take a boat and release the water to flood, and the soldiers left behind by Chen are all fish and turtles. ”

When the generals heard this, they were all convinced, and they went down to prepare. Guo Jia saw everyone leaving the tent, and couldn't help sighing: "Water and fire are ruthless, I'm afraid that the people in this battle city will suffer, I hope the national teacher doesn't blame me." ”
