He often goes up the mountain to collect herbs, and then cultivates Dan medicine himself. In that era of worshipping God, everyone was eager to cultivate immortality, and Guiguzi was no exception. He is a loyal supporter of this cause. His footprints are all over many places. It is said that he once picked a fairy grass in a deep mountain, and he immediately cultivated it into an elixir. That is, at this time, he was directly several decades younger, and this one achieved such an effect. Later, he lived with these elixirs for hundreds of years.
Moreover, in legend, he not only found the fairy grass to take, but also visited the immortals in the deep mountains and was taught the skills of immortals. It is also recorded that he can soar on the ground, fly directly to the clouds in deep valleys, and even walk on the clouds. It can be said that under the guidance of the gods and his own practice, he became a fairy.
His disciples are all over the world. During the Spring and Autumn Period and the Warring States Period, his disciples even gave advice to the kings of various vassal states, and even formed an independent military school. His disciples also carried forward his thoughts and made the legend of Guiguzi spread to this day. Even after Qin Shihuang knew that he was immortal, he wanted to be immortal, so he spent his whole life looking for it, but he couldn't find it.
