Immortals recorded in historical records

Fairy tales recorded in Historical Records are still household names. There are three sacred mountains in Bohai Sea, named Penglai, Abbot and Yingzhou, where immortals live. Qi Weiwang, Qi Xuanwang and Yan Zhaowang all sent people to look for the sacred mountain, inviting immortals, but people just found it and it was blown away by the wind. Legend has it that someone has gone home. There are immortals and elixirs on the mountain. Everything and animals are white, and palaces are made of gold and silver. From a distance, the mountains are like clouds. When we get there, Sanshan lives underwater. When you get close to it, the wind blows away and you can't reach it. At the time of Qin Shihuang, the alchemist Xu (Fu) of the Qi Dynasty wrote a letter asking for the elixir of life for the first emperor, so Qin Shihuang sent the Xu to send thousands of boys to the sea to seek immortality (see Book of Zen in Historical Records and Biography of Qin Shihuang). When Emperor Wu of the Han Dynasty arrived, Li, an alchemist, said that when he traveled to the sea, he met the immortal An Qisheng, who gave him dates as big as melons to eat, so that the immortal An Qisheng could go to Sanshen Mountain. When the immortal saw it, he would see people and hide if he didn't agree (Historical Records of Xiaowu).
