I am looking for a historical story of the Western Han Dynasty, about 400 words.

Luan Da (?-112 BC), Luan Da was a pharmacist in the palace of Liu Ji, King of Jiaodong during the period of Emperor Wu of the Han Dynasty. He studied alchemy from the same teacher as General Wencheng Shaowen. After being recommended to Emperor Wu of the Han Dynasty, he cleverly deceived Emperor Wu of the Han Dynasty into accepting him. Later, after completing the tasks assigned by Emperor Wu of the Han Dynasty, he showed his flaws and was cut in half. Emperor Wu of the Han Dynasty was fond of gods, so many famous magicians emerged during his reign. At that time, Lechenghou's sister was Liu Ji's princess and had no children. After Liu Ji's death, the sons of other concubines were made the king of Jiaodong. Princess Ding became a widow at a young age. Of course she couldn't keep it, so she had fornication with others. But she was afraid that the new king would know about it, so she tried every means to harm the new king. The two are constantly fighting each other. When Princess Ding learned that the young man was dead, she wanted to win favor with Emperor Wu of the Han Dynasty and rely on her as a supporter, so she asked her brother to recommend Luan Da to Emperor Wu of the Han Dynasty. It happened that Emperor Wu of the Han Dynasty felt a little regretful after killing the young man. He thought that the young man still had many secret recipes that he had not yet presented. What if there was a secret recipe for immortality among them? Seeing Luan Da felt like finding a treasure. Luan Da is a tall, handsome man who dares to speak big words without even blinking. When they met, he first reprimanded Emperor Wu of the Han Dynasty: "I once traveled to the sea and met famous immortals such as Anqi and Xianmen. These immortals are so noble, but they think that I am of low status. They will sneer at anything I say. They didn't believe me. I asked for a prescription for Liu Ji, the king of Jiaodong. They thought Liu Ji was just a small prince, so what qualifications did he have to make him an immortal? My teacher pointed out to me: "Gold can make a fortune, but rivers can make a fortune." Stop, the medicine of immortality can be obtained, and the immortal can cure it. "But I'm afraid that I will die in an unknown way like my senior brother, General Wencheng. It doesn't matter if I die, but after I die, the alchemists will be silent, and no one will dare to talk about alchemy!"

When Emperor Wu of the Han Dynasty heard this, he was unkind and quickly lied: "Your senior brother General Wencheng died of an overdose of horse liver. If you really have experience in your teacher's alchemy, there is nothing else I can't bear to do!"

Luan Da replied: "My teacher never begs for help, only people ask for him. Your Majesty, if you must hold an experience transfer conference with the gods, you must make the messengers of the gods noble, have their own dependents, and treat them as the most noble The guests should not look down upon him like this, and they must wear various seals given by His Majesty before he can be sent to deliver messages. Even so, it is still unclear whether the gods are willing to come to the meeting. In short, they are so busy! Success depends on your Majesty's performance."

After hearing this, Emperor Wu of the Han Dynasty was doubtful and thought: I have paid such a high price, and it is still unclear whether the gods will come to the meeting or not. How can I believe it? He volunteered to perform a small alchemy first, allowing Emperor Wu of the Han Dynasty to verify his identity and open his eyes. Luan Da's performance was a chess fight. The chess pieces collided with each other on the chessboard, which was dizzying. In fact, this is just a little magic: Luan Da coated the chess pieces with magnets in advance and used a magnetic steel rod to pull them under the chessboard. Of course, the chess pieces collided with each other. Emperor Wu of the Han Dynasty understood this trick and was overjoyed, so he appointed Luan Da as General of Five Benefits.

More than a month later, Luan Da was given four seals as promised: General Tianshi, General Dishi, General Datong and General Tiandao, and issued an edict: "In the past, Mr. Yu was able to dredge Jiujiang and guide the four rivers. But now the river is overflowing, no matter how many migrant workers there are, it will not work no matter how many slogans we say to fight for the survival of the levee. I have ruled the world for 28 years. If God is really willing to give me a capable person. , then it must be Luan Da. "The Book of Changes" mentions Feilong and Hongyan, isn't it the two of us? "So Luan Da was granted the title of Letong Marquis with a city of 2,000 households.

Not only that, Emperor Wu of the Han Dynasty also married Princess Wei to Luan Da. Princess Wei Chang was the eldest daughter of Emperor Wu of the Han Dynasty and Queen Wei Zifu, the biological sister of Prince Wei Liu Zhi, and the favorite daughter of Emperor Wu of the Han Dynasty. Emperor Wu of the Han Dynasty rewarded Luan Da, who was promoted to Prince Consort overnight, with 10,000 kilograms of gold and renamed his fiefdom as Princess Dangli. On the day the two got married, Emperor Wu of the Han Dynasty came to the scene to preside over the wedding ceremony. There were endless envoys of condolences and gifts. From the aunt of Emperor Wu of the Han Dynasty to the generals and ministers, all the civil and military officials from the Manchu Dynasty prepared grand banquets and sent rich belongings to the new prince-in-law's house, and the whole city of Chang'an was decorated with flowers. The grandeur of the event was unprecedented and rarely seen in the future. A scene that was both solemn and comical appeared: Emperor Wu of the Han Dynasty carved a jade seal of "General Tiandao" and sent an envoy holding the jade seal and wearing bright feathers. The moonlight fell like mercury. The envoy stood on the white thatch grass. Luan Da also wore a feather coat and stood on the white thatch to receive the jade seal, indicating that the two parties were equal in status. From then on, Luan Da often performed rituals at home at night and invited gods to come to the world. Such a grand pomp and such a distinguished status still could not move the gods. Luan Da had no choice but to come up with a plan and told Emperor Wu of the Han Dynasty that he would dress up and enter the sea to pay homage to his teacher.

In just a few months, Luan Da was transformed from a little-known pharmacist to the emperor's consort and a five-profit general wearing six jade seals. He became rich as fast as a rocket. , which made the colleagues on the eastern coast blush and sigh, regretting why they had not thought of this move. For a time, everyone was rushing to brag that they had the secret recipe to attract gods. Supernatural incidents began to appear one after another in the empire. In the summer of this year, a Fenyin wizard named Jin presided over a sacrificial ceremony for the people next to Wei Xuan's Houtu Temple. In a blink of an eye, he saw the ground bulge, taking on the shape of a hook. They dug up the mound and unearthed a tripod. This tripod is larger than the other tripods, with strange patterns carved on it, but no inscriptions.

The local officials reported to Emperor Wu of the Han Dynasty. Emperor Wu of the Han Dynasty was afraid of being deceived. He first sent people to torture the wizard named Jin, but no obvious scam was found, so he invited Ding to Ganquan Palace. Emperor Wu of the Han Dynasty followed Ding religiously, preparing to take Ding to the palace. It is dedicated to the Emperor of Heaven. When we walked to Zhongshan, the weather was sunny and cloudless, but for no reason, a yellow cloud floated over, as big as a canopy. A unicorn happened to run by. Emperor Wu of the Han Dynasty bent his bow and arrow in a daze, and somehow managed to kill the unicorn with one arrow. He took it as a sacrifice sent from heaven. When they arrived in Chang'an, all the civil and military officials suggested that the tripod should be respected. Emperor Wu of the Han Dynasty asked in confusion: "The Yellow River has repeatedly burst, and the harvest has been poor for several years. Fortunately, the grain has been abundant this year, and I haven't had time to offer sacrifices to heaven. What's wrong with this tripod?" Appeared suddenly?"

The official in charge boasted: "Baoding will only appear when you meet the Holy Lord. As soon as Baoding appears, Huang Yun and Unicorn will follow. Xiangrui, Your Majesty, you are a saint like the Yellow Emperor. Emperor Wu of Han led a large group of troops to Yong County to worship the Five Emperors. Gongsun Qing of Qi presented a wooden slip to Emperor Wu of Han and said: "This book is Shen Gong, a good friend of the famous immortal An Qisheng." According to legend, the book said that the holy master of the Han Dynasty should be the great-grandson of the great ancestor Liu Bang. Your Majesty, you are the great-grandson of our great ancestor! So you should imitate the Yellow Emperor and ascend Mount Tai to become a Buddhist monk. When the Yellow Emperor was worshiping God on the outskirts of Yong County, a dragon with a dewlap hanging from its neck and beards on its cheeks came down from the sky to greet him. After the Yellow Emperor rode on the dragon's back, all the civil and military officials and harem concubines followed him. There were more than 70 people there, and then the dragon soared away. The other officials with junior positions could not get up, so they all grabbed the dragon's beard and refused to let go. As a result, the dragon's beard was broken and Huangdi's bow fell off. When the people saw the Yellow Emperor ascending to heaven, they all held their bows and dragon beards and cried loudly, crying that their good emperor became an immortal alone and abandoned the people of Li. "

Emperor Wu of the Han Dynasty was fascinated by what he heard, and sighed: "Alas! If I could ascend to heaven like the Yellow Emperor, my wife and children would be like taking off pairs of shoes to me, there would be nothing to miss. "So he worshiped Gongsun Qing as his husband and asked him to go to Mount Taishi to wait for the gods to come. Emperor Wu of the Han Dynasty himself worshiped the gods "facing the sun and the moon at night", saying in his heart that the gods and gods should come quickly and pick me up to become an immortal. < /p>

The anxious Emperor Wu of the Han Dynasty asked Luan Da when he would go into the sea. How dare he risk his life? The spies followed him, and they reported that Luan Da spent all his time and boasted about the magic conch, but there was not even a shadow of the god. Emperor Wu of the Han Dynasty knew that Luan Da had been tricked. The next year, Luan Da returned to Chang'an and returned to his hometown. I met the teacher, but the teacher's alchemy skills were exhausted and could not satisfy His Majesty's request. At this time, Luan Da was exhausted and the scam could no longer continue. Emperor Wu of the Han Dynasty was furious and killed Luan Da in half. The eldest princess has become a widow. "My lord!" These words pleased Emperor Wu of the Han Dynasty, so he kept the tripod in the palace and worshiped it from time to time.
