Ma Chao sent soldiers to take turns scolding him every day. Cao Hong's anger kept building up and he wanted to fight, but Xu Huang tried hard to persuade him.
After Xu You saw this situation, he said to Ma Chao: "On the ninth day, we can let the soldiers pretend to be slack, and then ambush a few groups of troops, and then a big thing can be accomplished."
On the ninth day, Ma Chao asked the soldiers to dismount, and then sat on the grass, looking very tired. After Cao Hong saw it at the pass, he thought it was a good opportunity and led three thousand soldiers and horses to kill him from the pass.
The Xiliang soldiers were very panicked and ran away. Cao Hong kept pursuing them. At that time, Xu Huang was closing the gate and counting the food and grass. He was very surprised when he heard that Cao Hong had led 3,000 soldiers and horses to fight. He quickly arrived with his army. Call Cao Hong back.
At this moment, there was a loud shout from behind. It was Ma Dai who came over with his soldiers and horses. When Cao Hong and Xu Huang were about to retreat, a drum sounded and two teams of people on the back of the mountain rushed out. Ma Chao on the left and Pang Pang on the right. Germany, three-way siege, Cao Hong could not resist, and most of the soldiers and horses he brought out were broken, and he forced his way out of the siege, preparing to return to the pass.
Soon after, Xiliang soldiers came over, and a group of people appeared in the pass. The leader was Yu Yi. Seeing the enemies all over the pass, Cao Hong knew that he could no longer defend Tongguan, so he gave up on Tongguan.
Pang De led his soldiers and horses to pursue him, and met Cao Ren's soldiers and horses. He rescued Cao Hong. Pang De was afraid of other ambushes, so he returned to Tongguan with Ma Chao's support.
Inside Tongguan, Ma Chao held a banquet to celebrate his victory, and Yu Yi was the first among the guests.
Yu Yi paid his respects and said: "They say that the Xiliang army is brave and good at fighting. I think it is more than that. The ability to capture Chang'an and Tongguan in a few days shows not only courage, but also strategy!"
Ma Chao returned the gift and said, "Those are all the clever ideas of Military Advisor Xu You. We should thank him properly!"
Yu Yi smiled and said: "What are you saying, general? My eldest brother and your father are loyal ministers of the Yidaizhao. We have a common enemy. Aren't we a family? A family should not speak the language of two families."
He replied: "Haha, then I'll stay out of the house!" After finishing his drink, Yu Yi and Xu You stood up and drank all the wine in the bowl.
After drinking for three rounds, Ma Chao asked, "I don't know what brother is planning. How about you help me attack Xudu together?"
Yu Yi said: "Now that Chang'an and Tongguan are lost, Cao's thieves will definitely come to defend themselves with troops and horses. We should help the Xiliang army to fight against Cao's thieves. However, I only have 30,000 troops in my hands, which is very weak. I plan to go Xichuan persuaded Liu Zhang to add my eldest brother's troops from Jingzhou and Sun Quan from Jiangdong in the alliance, so that a four-pronged army could be formed, and the powerful combined force would surely defeat the Cao thieves."
Ma Chao nodded and said: "In that case, the Xiliang Army and I will wait for your good news!"
Yu Yi bowed and drank all the wine in his hand.
In the Tang Lin Army, Yu Yi had stipulated that there should be democratic centralism, so after the banquet dispersed, he called everyone to hold a meeting at the temporary residence.
Many people did not understand Yu Yi's decision. Lei Chunze directly came out and asked: "Isn't the purpose of our army to help the Han Dynasty and eradicate Cao Cao, the leader of the thieves? Now Xiliang Ma Chao and Han Sui have 200,000 mercenaries. We have captured Chang'an and Tongguan, and will soon invade Xudu, why don't we join them and leave alone?"
Huang Shumin echoed: "Yes, I also think this is a good opportunity. Do we want to let it be missed like this?"
Wu Chenggong said: "Young Master, let's attack Xuchang in one go and establish our own political power."
Yu Yi didn't expect that everyone's voices against him would be so uniform this time. He walked up to Xu You and said, "Military advisor, what do you think?"
Xu You said: "I have been in the Xiliang Army during this period. I found that the Xiliang Army is extremely brave, but lacks strategy. If we join the Xiliang Army, we will definitely be squeezed out. We will not be able to give full play to the advantages of our army by obeying Ma Chao's deployment. Furthermore, it shows that Uncle Liu is preparing to unite with the Xiliang Army. Once we merge with the Xiliang Army, will it arouse suspicion in Jingzhou, saying that we support our own troops? In the past, the eighteen princes united, but were led by Lu Bu The fundamental reason for the retreat of the troops is lack of unity. Tang Lin's army will also face the same problem when entering the Xiliang army. If we have the dominance of these more than 200,000 troops, then we can try to attack Xudu. If it doesn't work, sooner or later If we are defeated by Cao's army and lose our existing 30,000 soldiers, it will be too late to regret it!"
Yu Yi was very happy after hearing this and said, "The military advisor's words deeply touched my heart!"
Xu You bowed and said: "The young master used the alliance with Liu Zhang of Xichuan as an inducement, found a reason to break away from the alliance, and successfully crossed Luoyang and Tongguan, passed through Chang'an, and entered Xichuan. This strategic plan is also very clever."
Yu Yi nodded and said: "Yes, after we entered Xichuan, we still didn't know Liu Zhang's attitude, so it is necessary to conserve our strength and wait and see what happens."
The conversation between the two people as if no one was around made others a little jealous. Of course, they also understood the strategic significance of leaving alone, which could be regarded as unifying their thoughts.
Cao Hong left Tongguan and went to see Cao Cao.
Cao Cao said: "I have been with you for ten days, and now you have lost Tongguan on the ninth day?"
Cao Hong said: "Xiliang Ma Chao insulted them for nine days. I was really angry. When I saw them all lying on the ground sleeping, I thought they were slacking off, so I took advantage of the situation and rushed away. I didn't expect to fall into the opponent's trick."
Cao Cao said: "Cao Hong is young and has a bad temper. Xu Huang, you should persuade him!"
Xu Huang looked a little aggrieved and said: "I have tried to persuade him many times. Everyone knew that I was counting food at the gate that day, but by the time I knew about it, Cao Hong had already gone down to the gate to fight. I was afraid that he would encounter When he saw danger, he rushed over and fell into the opponent's trick."
When Cao Cao found out what happened, he was very angry and demanded that Cao Hong be beheaded immediately. The officials begged for mercy and were exempted. Cao Hong confessed and left temporarily.
As soon as Cao Hong left, Sima Yi arrived with his army.
Cao Cao asked: "This time we captured Tongguan, did Yu Yi also attack?"
Xu Huang nodded and said: "Yes, Yuyi attacked from the east of Tongguan. After we left the pass, he secretly occupied Tongguan."
Cao Cao asked again: "It is said that Yuyi only has 30,000 troops. Didn't you besiege him at the foot of Shouyang Mountain?"
Sima Yi knew that Cao Cao was very angry, so he immediately knelt on the ground, lowered his head, and said: "We seized the ferry and surrounded Yu Yi. Unexpectedly, Yu Yi used the Bagua formation. After our army entered the formation, it fell into a state of chaos. , General Le Jin was also seriously injured!"
After hearing this, Cao Cao sighed and said: "This time he must be colluding with the Xiliang army. We must find a way to annihilate him in one fell swoop and eliminate hidden dangers."
All the soldiers expressed their determination, so Cao Cao led his troops and horses towards Tongguan.
