The Battle of Guandu was crucial to Zhang Xiu.
After making arrangements for Yizhou, it was too late to wait for Zhang Qian and Hu Che'er to come back. He ordered Qi Zhu as his personal guard and led the remaining 2,000 Jinggan troops and 5,000 cavalry to Luoyang day and night.
Wei Yan was frustrated when his way was blocked by Yu Jin's army.
When he stationed troops at Hangu Pass, Wei Yan knew that there would be a tough battle to be fought, and he was well prepared. Before the troops were sent to Luoyang, he sent people out early to investigate the situation in Luoyang City, and arranged internal intelligence in the city. This made the siege very successful.
Unexpectedly, Shou Yujin's reaction was also very quick.
After the city of Luoyang was defeated, Yu Jin knew that he could no longer hold it, and there was no point in resisting anymore. He decisively chose to abandon Luoyang City, retaining his remaining troops and retreating to Hulao Pass, guarding the intersection and lowering the stronghold, preventing Wei Yan's army from leaving eastward, thus destroying Cao Cao's plan.
After occupying Luoyang City, Wei Yan did not dare to stay longer and immediately led his army to kill Yu Jin.
Time was running out, and Wei Yan even went to the battlefield in person to break through the Wei army camp. Yu Jin also tried his best to defend the military stronghold. The two sides fought fiercely in front of the military stronghold and suffered heavy losses. The water of the Yiluo River turned red.
The two armies were in a stalemate.
"What should we do? Your Majesty has already learned about this and was on his way here. We failed in the battle, which led to the interruption of His Majesty's plan. We are really the sinners!" Wei Yan fidgeted in annoyance and paced back and forth in the military tent.
Zhang Xian said: "General, don't be anxious. Lord Jia has sent military advisor Xu here. When the military advisor arrives, he will definitely be able to defeat the enemy before the king."
"Commander Xu?" Wei Yan stared at Zhang Xian, "But Xu Shu?"
Zhang Xian nodded.
Wei Yan thought for a while: "That's fine! Although Military Advisor Xu doesn't have any good strategies, but he can be valued by the king, his ability must be considerable."
While he was talking, Xu Shu had already arrived after a long journey.
After becoming an adviser to Zhang Xiu's army, Xu Shu's talents were not fully utilized. It wasn't that Xu Shu's abilities were fake, but that Zhang Xiu had so many talented people, and Zhang Xiu was brave and resourceful, that his talents were buried.
But as counselors, Jia Xu, Li Ru and others knew Xu Shu's abilities.
Therefore, when the war in Luoyang was interrupted, Xu Shu was immediately asked to come to Luoyang.
"Two generals, you have been waiting for a long time!" Xu Shu walked in quickly and said while taking off his windbreaker, "Although it is the golden autumn moon, the weather is still very hot. Is there any cold water?"
Wei Yan looked at Xu Shu in surprise, reacted, and immediately said: "Yes, yes!" After saying that, he immediately picked up the kettle and poured a cup for him.
The cold water was sweet and refreshing, and Xu Shu drank it all in one gulp.
Then he looked at Wei Yan and Zhang Xian and said with a smile: "The two generals came all the way and are very tired. How about you allow me to rest for the night and discuss military affairs tomorrow?"
Wei Yan and Zhang Xian were so anxious, how could they wait?
Wei Yan frowned: "Commander! The enemy is right in front of you. The king will be here soon. We'd better discuss it early. With the result in hand, if you want to sleep, we won't dare to stop you."
Zhang Xian nodded as if pounding garlic.
Xu Shu smiled calmly and said: "Before coming to Luoyang, I was very anxious and thinking about ways to defeat the enemy. But after entering Luoyang, I was no longer anxious. There is no need for the two generals to be anxious. Just eat well and sleep well, and let the whole army rest. After three days, the enemy army will be defeated!"
"...?"
Wei Yan and Zhang Xian's eyes met and they saw the confusion in each other's eyes.
Zhang Xian asked: "Commander, if we don't send troops to fight, will Cao's enemy commit suicide?"
Xu Shu smiled and pointed at Zhang Xian: "What General Zhang said is true. The place where Cao's army is located is tantamount to self-destruction. Don't be anxious, two generals. The result will be there in three days. You just need to prepare more boats and rafts. Just put away the water utensils.”
Wei Yan was puzzled: "We are on land, so why use water utensils?"
Zhang Xian also looked puzzled: "The Yiluo River is a small river. The water level is not high. We cannot use the power of the water to defeat the enemy. Why prepare water tools?"
Xu Shu said: "This is not known to the two generals."
The two looked at each other, then clasped their fists and said, "Please ask the military advisor for advice!"
Xu Shu took out his fan, fanned it slightly, and asked with a smile on his face: "Two generals, do you think the sun is getting stronger in the past few days?"
Wei Yan and Zhang thought for a moment and nodded.
Xu Shu: "That's it. It's the end of July and the autumn of August. After such a day, there will be heavy autumn rains. By then, the Yiluo River will definitely rise. It can be blocked upstream at night. At the water mouths everywhere, when the water comes out, take a high boat and release the water. Once the water is flooded, the Wei army will be defeated."
Wei Yan asked: "How did the military advisor know that there would be a heavy rain in three days?"
Xu Shu smiled confidently and said: "A soldier who does not understand astronomy, does not know the geographical advantages, does not know the strange gates, does not know the yin and yang, does not understand the formation map, and does not understand the military strength, is mediocre. A certain person has calculated that a heavy rain will come in three days. A general only needs to follow orders."
Between the two of them, Xu Shu was full of confidence, but with a bit of doubt, he went down and followed the instructions.
Three days later.
The sun had been shining brightly for several days. On the third night, a strong wind suddenly came, the sky was overcast, and the air was filled with thick moisture. It looked like a heavy rain was coming.
Wei Yan and Zhang Xian were frightened for two days.
When the strong wind blew, the two people's anxious hearts finally relaxed.
At this time, Xu Shu was wearing a moon-white long-sleeved scholar, a scarf on his head, and a feather fan in his hand. He was sitting in the Chinese army tent with a calm and calm expression, as if everything was under control.
Wei Yan and Zhang Xian led their subordinates in.
"Generals, obey the order!"
As soon as the military order came out, Xu Shu's face suddenly froze. The originally scholarly face turned cold and ruthless.
The soldiers did not expect Xu Shu to be so capable and immediately stood in awe.
Xu Shu grimaced: "General Zhang, listen to the order! After the heavy rain, the water level will inevitably rise sharply. After the water is released to submerge, the sergeants of each battalion must rush down in boats and rafts in the shortest possible time, shoot Cao's army, and must not teach his troops to escape." !”
Zhang Xian: "Here!"
Xu Shu continued: "General Wei listened to the order! He immediately led his troops to lie high in the mountains and forests. When the water flooded the Wei army's stronghold and the army was defeated and retreated, he immediately retreated and went straight to Hulao Pass. He could falsely claim that the Wei army had deserted and defrauded them. There must be no mistakes at the pass!”
Wei Yan: "Here!"
After the plan was decided, the raindrops outside the military tent could be heard pattering. Just by hearing the heavy rain, one knew that it would rain heavily tonight. Suddenly, the whole army stood in awe of Xu Shu.
Xu Shu waved his feather fan: "Action!"
"Here!" the generals shouted.
…
Heavy rain poured down, and Yu Jin sat in the Wei army's tent, listening to the heavy rain outside, and felt uneasy. At that time, in order to intercept Jing's army, he ordered people to block the way along the river with the help of favorable terrain. However, with the heavy rain tonight, this favorable terrain became critical.
"General!" At this time, a hidden guard rushed in, "Xu Duxun's military advisor has an urgent order."
Yu Jin suddenly had a bad premonition and immediately rushed over, grabbed the secret letter and tore it open. The letter read: "General Yu, when I looked at the sky recently, I saw that a heavy rain was coming in the land of Sili. The Jing army also Those who have favorable celestial phenomena need to pay more attention.”
After reading it, Yu Jinqin broke into a cold sweat.
At this moment, all I could hear was thousands of horses racing outside the tent, and a roaring and thundering sound that shook the sky and the earth. Suddenly, Yu Jin's eyes widened in shock.
