In order to live forever, Emperor Wu of the Han Dynasty, at the suggestion of the alchemist, sent someone to build a high platform with cypress beams in Zhangjian Palace, called "White Balcony"; A 20-foot-high copper column was cast on the stage, and a copper immortal holding a copper plate was cast on the top of the column. That copper plate is called "dew-bearing plate", which is used to receive the "fairy dew" in the sky. The alchemists lied to Emperor Wu of the Han Dynasty, saying that drinking this kind of "fairy dew" with jade powder can make you live forever. Emperor Wu of the Han Dynasty had no doubt that he drank dew as soon as it appeared. He drank like this for more than a year. Instead of becoming an immortal, he was ill. He asked doctors to take medicine and wizards to pray for ghosts and gods. The doctor finally cured him, but he attributed it to the wizard.
Soon, Emperor Wu met another alchemist named Luan Da. Luan Da is good at bragging. As soon as he saw Emperor Wu of the Han Dynasty, he spoke wildly. He said: "I often travel at sea and have many contacts with An Qisheng, a fairy and an envious disciple. They think that my position is not humble, and they have refused to take out the fairy's' fairy recipe'. My teacher became a fairy. He once said to me: cinnabar can be refined into gold, Poseidon can invite it, and there must be a medicine for immortality. Emperor Wu of the Han Dynasty quickly said, "As long as you can get me an immortal prescription, I will give you anything."
Seeing that Emperor Wu of the Han Dynasty had been trapped, Luan Da further lured him and said, "My teacher has never asked anyone, so I can only ask others to ask him. If your majesty really wants to invite my teacher, he must choose a prestigious person as an envoy, give him an official position and be a relative of your majesty. Only in this way will my teacher be willing to receive your majesty's special envoy and hand over the prescription of immortality. "
Emperor Wu of the Han Dynasty was persuaded, so he was asked to cast a spell to his face. Luan immediately took out two pieces from his sleeve and gave them to Emperor Wu of the Han Dynasty, saying, "Please look carefully. I can make these two pieces fight, but they won't open. " With that, he took the pieces in one hand and put them on the chessboard. As soon as he let go, the two pieces really went straight to one place. He opened it with his hand, then let it go, and the two pieces met again. In fact, these two pieces were carefully polished by Luan Da with a magnet. Emperor Wu of the Han Dynasty, on the other hand, thought Luan Da was superb and even worshipped him as the Five Generals. Later, he was named General Shi Tian, General Di and General Datong. At the same time, he was named Le Tonghou, a food city with 2,000 households, and was given exquisite houses, including slaves, chariots and horses, curtains and other gold and silver utensils. Moreover, Emperor Wu of the Han Dynasty betrothed a princess born in Wei Ruyun to Luan Da as his wife. Soon, Emperor Wu of the Han Dynasty added Luan Dawei as "General of Heaven". In this way, in just a few months, Luan Da actually defrauded six gold seals and became the son-in-law of the emperor. He got something he didn't even dare to think about.
Luan Da won so many titles and married the emperor's daughter, which was very noble for a period of time. He couldn't find a reason to refuse, so he had to bite the bullet and invite the immortal to the front of Emperor Wu of Han Dynasty. Emperor Wu of the Han Dynasty was fooled several times and was wary of Luan. As soon as Luan Dagang left Chang 'an, Emperor Wu of the Han Dynasty chose a few confidants to follow him secretly to see what he was doing. Luan Da went straight to the East with a lot of money, but he just climbed to the top of Mount Tai, walked around and came back. However, when he met Emperor Wu of the Han Dynasty, he made up a set of lies at random. Emperor Wu of the Han Dynasty waited for his confidant to come back, only to know that Luan Da didn't go to the East China Sea at all, let alone see any immortals. Unexpectedly, Emperor Wu of the Han Dynasty finally fell for it. He became angry from embarrassment and immediately sent someone to arrest Luanda and behead him.
In this way, Emperor Wudi lost his daughter and spent money, but he still couldn't find out where the immortal was.
In order to become immortal, Emperor Wu of the Han Dynasty allowed alchemists to talk nonsense, treat them as distinguished guests and treat them with high officials and generous salaries. Even the princess joined in, and both people and money were empty, becoming the laughing stock of the world. It can be seen that all acts that violate the laws of nature and science are not worth the loss, but also cause endless harm. Longevity may not be difficult, and it needs to be achieved through scientific health preservation methods, rather than relying on the so-called "panacea."
