The reason why Xun Yu made a judgment so quickly was actually based on evidence.

The Captain of the Golden Touching was used by Cao Cao to dig graves, that is, to rob tombs. In ancient times, many people started by robbing tombs, such as Lu Bu, Cheng Zhijie and others, Cao Cao was also one of them, and was even named the ancestor of the tomb robbery world.

The reason why Cao Cao was able to get the title of Master Zu was related to this golden captain. The reason why Cao Cao was able to fight year after year had a lot to do with Captain Mojin. It was precisely because of the large amount of money brought by tomb robbing that he was able to recruit more soldiers and form the Tiger and Leopard Cavalry.

When we read history books, we often see that Cao Cao is short of food, but he is still constantly fighting, and he has to wage several wars every year. But we have never seen Cao Cao's lack of money, many people will say that there is the support of the Wei family and Cao Hong, not to mention the two rich people, even if Cao Cao is given ten rich people, they still can't support so many wars.

Emperor Ling got a lot of money from selling officials, right? Lu Bu got a lot of money from digging north, right? Dong Zhuo has a lot of wealth in Luoyang, right? But it was only a few years since Dong Zhuoxi moved to Li Dao and Guo Yan were defeated, and all these riches were lost.

Cao Cao from 190 to 200 years, in the past ten years, he fought the Yellow Turban, defeated Montenegro, fought Yuan Shu, attacked Liu Bei, killed Lu Bu, descended Zhang Xiu, welcomed the emperor, broke Yuan Shao, and fought dozens of battles, although it was difficult, but they all persevered, and the scale of the army was not small, tens of thousands of troops were moved, and each war cost hundreds of millions.

This captain who touched gold was to gather wealth for Cao Cao, and he didn't do murder work at all, and he couldn't do murder work. If this kind of military crossbow wants to be used by one person, it requires a lot of strength, and non-wrestlers can use it, and the body of the tomb robber needs to be thin and weak, and he can't pull this crossbow at all.

Moreover, this kind of crossbow is dedicated to Zhang Yijun, and Cao Cao will not manufacture it at all, because the process is very complicated, and there are as many as seventy or eighty parts, and the specifications are slightly worse than they can be installed together.

Although Cao Cao was also captured, each one was very precious, and all of them were equipped in his own personal guards, led by Xu Chu.

That is to say, Cao Cao took all the captured crossbows to Nanyang, and Cao Cao would not send someone to assassinate the emperor, what he wanted was nothing more than to seal the prince and the king, and if he killed the emperor, his attempt to seal the prince and the king would not be realized.

Then there is only one possibility, that is, Zhang Yi sent someone to assassinate the emperor.

Xun Yu really wronged Zhang Yi, and Zhang Yi really didn't dare to betray the reputation of assassinating the emperor. Although this matter was done by his subordinates, it was not instructed by Zhang Yi, but decided by the Assassins themselves.

The cause of the incident still has to start with Master Shang, this assassin was originally a sergeant of the Shang Master and Apprentice Army. Later, he was selected into the intelligence rafters and came to Shi Xiu's hand, because he was from Xuchang, so he was sent over.

The soldier had received the favor of Master Shang, and the Emperor's proclamation of the Emperor's sacrifice to the heavens mentioned the death of Master and Apprentice, much to the Assassin's anger. So he decided to take the opportunity to assassinate the emperor, but his superiors did not agree, and he quarreled with his superiors, and finally broke up.

The Assassins decided to take matters into their own hands and orchestrated the assassination.

When Zhang Yi's intelligence officers to Xuchang learned that the emperor had been assassinated, they immediately decided to hide and wait for the limelight to pass before coming out to collect intelligence.

Xun Yu was arresting suspicious people in Xuchang City for interrogation, and those scoundrels of the day were also among them. On the other side, he sent someone to inform Cao Cao to withdraw his troops, the emperor had no more days left, and Cao Cao needed to come back to preside over the overall situation.

After Cao Cao arrived in Wancheng, he confronted Zhang Yi. Cao Cao also inquired and understood that Zhang Yi had at least 50,000 troops in Wancheng, and he could only fight 100,000 soldiers, and the elite level of soldiers was much worse than Zhang Yi's soldiers. In this case, he really didn't dare to attack the city, but instead invited Zhang Yi to fight in the field, hoping to restrain Zhang Yi's soldiers with the elite cavalry.

Zhang Yi also hated Cao Cao because of the death of his master and apprentice, and he led his troops out of the city to fight against Cao Cao, a small fight in three days and a big fight in five days. The two sides come and go, and there are injuries to each other, but they are both within an acceptable range.

Li Jing didn't have much to do about Zhang Yi's decision to be angry. Originally, according to his idea, it would be good to hold Wancheng directly, Cao Cao would consume grain and grass outside the city, and he would definitely retreat in the end. Cao Cao's army is large, and the consumption of grain and grass is also large, and he will withdraw his troops after holding out for long.

But Zhang Yi didn't listen to this, and if he didn't kill Cao Bing, Zhang Yi always felt unhappy.

Zhang Yi's soldiers are strong and fierce, and he has always had the upper hand, and the casualty ratio in the battle is one to two or even one to three or four. If he fights like this for three or five months, Cao Cao will definitely not be able to bear the loss, and being defeated by Zhang Yi will definitely be a sure thing. So Li Jing didn't persuade too much, just be careful not to let Cao Cao calculate, it's okay.

Zhang Yi and Cao Cao fought a few times, and the anger in his heart also improved a lot, so he stopped sending troops. He felt that it was not very cost-effective to fight Cao Cao like this. There are many more people under Cao Cao's rule than Zhang Yi, even if Cao Cao's 100,000 people are killed, he can still pull up an army of 100,000 in a year or two. But even if Zhang Yi himself is counted as 30,000 people, he is a little injured.

The population under Zhang Yi's rule could only allow him to have more than 300,000 soldiers and horses, and he used 90,000 soldiers to attack Yizhou, 70,000 soldiers and horses in the north of Jingzhou, 60,000 soldiers and horses in the north of Yangzhou and Runan, 30,000 soldiers and horses in Shouchun, 50,000 soldiers and horses in the counties and important military towns of Jingyang Prefecture, and 30,000 soldiers and horses in Jiaozhou. Navy soldiers and horses are not counted among them, because these soldiers generally do not go ashore to fight, and their combat ability on the shore is still much worse.

Zhang Yi avoided the battle, and Cao Cao was also a little anxious. Just when he was trying to lure Zhang Yi into battle, Xuchang quickly reported that the emperor had been assassinated.

After Cao Cao heard this, he was stunned. He can have today's achievements thanks to the emperor, if the emperor dies, he will want to use the Han family to act in the future, but it will be troublesome.

Cao Cao looked at the letter Xun Yu gave him, on which Xun Yu's guess was written. Cao Cao slapped the table fiercely and said angrily: "Zhang Yi, you are so ruthless!" ”

But Cao Cao had no choice but to order the withdrawal of his troops.

However, it is not so easy for the army to retreat, they are only four or five miles away from Wancheng, as long as they withdraw their troops, they will definitely attract Zhang Yi's attention. Zhang Yi would definitely send troops to pursue, Cao Cao immediately summoned Xun You and Jia Xu, and asked them: "Now that the emperor has been assassinated, I need to rush back to Xuchang as soon as possible, can you make me withdraw my troops safely?" ”

Xun You said: "The lord can let the soldiers retreat in batches, camp along the way, and then use the cavalry to rear. The army retreated alternately and retreated to Bowang, where flammable materials could be piled up in the city and burned Bowang to block Zhang Yi's pursuit. ”
