Since Cao Cao killed Lu Bu, Cao Cao has been even more reckless in the court. Even Emperor Han Xian didn't dare to speak out.

Once, Cao Cao took Emperor Xian and hundreds of officials out of the city to hunt. At this time, a big deer jumped out of the thorns on the hillside, and Emperor Han Xian missed three arrows in a row, so he asked Cao Cao to shoot. So Cao Cao borrowed the treasure carving bow and golden loquat arrows of Emperor Xian of the Han Dynasty to shoot. Shot right on the back of the deer. At this time, when the civil and military officials saw the golden loquat arrow stuck in the deer's back, they thought that it had been shot, so they all shouted long live.

At this time, Cao manipulated the horse to go straight out and blocked in front of Emperor Xian. Accept everyone's worship. When the civil and military officials saw this, their faces changed. Guan Yu saw that Cao Cao was so rude, and he raised his knife and slapped the horse, and was about to step forward to kill him. Liu Bei hurriedly stopped Guan Yu, and bowed to Cao Cao to congratulate: "The prime minister's good archery skills are really rare in the world. ”

Cao Cao smiled and said, "This is all thanks to the Son of Heaven!" After that, he turned the horse's head to congratulate Emperor Xian of the Han Dynasty, but did not return the treasure carving bow to Emperor Xian, but hung it himself and took it out of the paddock.

After Emperor Xian returned to the palace, he talked to Queen Fu and Guozhang Fu about hunting, and couldn't help but burst into tears. Fu Wan recommended his uncle Dong Cheng to Emperor Xian, saying that Dong Cheng could get rid of Cao Cao, so Emperor Xian bit his finger and wrote an edict with blood, asking Queen Fu to sew it in the jade belt, and then Xuan Dong Cheng entered the palace and gave him the jade belt brocade clothes.

When Dong Cheng came out, Cao Cao was waiting in front of the palace, and saw Dong Cheng wearing a brocade robe and jade belt given by the emperor, and suspected that there was a ghost in it, so he ordered his attendants to forcibly untie the jade belt. Cao Cao took the jade belt and looked at it for a long time, but found nothing abnormal, so he asked Dong Cheng to take off his brocade robe and check it.

Cao Cao put the brocade and jade belt on his body and said to Dong Cheng: "How about Uncle Guo give me this brocade and jade belt?" Dong Cheng pretended to be calm and said: "If the prime minister likes it, he will stay." Cao Cao smiled and said, "I was just joking just now, how can I ask for the things given by the emperor?" After that, he returned the brocade clothes and jade belt to Dong Cheng.

Dong Cheng resigned Cao Cao and returned home, carefully inspected the brocade clothes and jade belt, and found nothing special.

After a long time, he fell asleep on the desk, and the sparks that flew from the wick fell on the jade belt, setting it on fire. Dong Cheng woke up and quickly extinguished the fire, only to see a piece of Sujuan with blood stains slightly exposed in the corner of the beaker.

Dong Cheng took out Su Juan and saw that it was the blood book of the emperor. After reading the blood book, he was filled with grief and indignation. The next day, Dong Cheng made an alliance with the ministers Wang Zifu, Chongji, Wu Shuo, Wu Zilan, Ma Teng, and Liu Bei and signed a letter of righteousness to jointly get rid of Cao Cao and support the Han family.

Liu Bei was afraid that Cao Cao would be suspicious, so he came up with a plan to keep his eyes on it, and only watered and planted vegetables in the back garden every day. Guan Yu, Zhang Fei asked him why he didn't care about the big things in the world, but he did such a small thing. Liu Bei said that he had a point. Guan Yu and Zhang Fei didn't ask any more.

From the historical event of the secret edict blood book, it can be seen that Emperor Xian of the Han Dynasty at that time still had ideas. Under the tight control of Cao Cao. At least not numb. Because at that time, Cao Cao coerced the Son of Heaven to order the princes. Emperor Xian's behavior was strictly controlled, and he could behave like this. It can be seen that Emperor Xian of the Han Dynasty was helpless in the environment at that time.

Emperor Xian of the Han Dynasty made efforts to maintain the ideal of peaceful reunification of the Han family. At the time, it seemed a bit difficult. Because Cao Cao firmly controlled the upper and lower levels of the imperial court.

Although the secret edict blood book did not succeed in the end, it still alarmed the princes of the troubled times at that time. Among them, especially Yuan Shao. has always regarded Cao Cao as a thorn in the eye and a thorn in the flesh. It had a far-reaching impact on the later Guandu War.

Although this small operation to maintain the peaceful reunification of the Han family was unsuccessful. However, it stimulated people's fighting spirit, and the later formation of the Three Kingdoms also had a great impact.

After the failure of the secret edict blood book, the possible daily behavior of Emperor Xian of the Han Dynasty was even more restricted by Cao Cao and others. At the same time, this also realistically illustrates the corruption and severity of the Cao Wei regime at that time.
