I'm Really Not An Expert

Xu Qing traveled to a world with gods, ghosts and monsters, thinking that he was just an ordinary person who would never die. Suddenly one day he awakened to his talent "Tao follows nature".
He played the song "A hundred birds come to the phoenix", and it turned out that there was a vision of a hundred birds gathering.
He chanted "Kill one person in ten steps, leave no trace in a thousand miles", which became a unique sword technique.
He wrote that the days are short and bitter, and it became a magical power that contains the avenue of time.
He left "Xuanzong of Heaven and Earth, the fundamental root of Wan Qi. Cultivate for hundreds of millions of kalpas and prove my magical power" on the Tianshi Wall of Longhu Mountain, which became the golden light mantra of Taoism's top body-protecting magical power.
He wanted to write the "Tao Te Ching", but no, the world couldn't bear it.
