Legend has it that a long time ago there was a monster in Sheepwhisker Town, which was possessed by the evil spirit of the beast. This monster was like a humanoid beast.

Later, a kind-hearted immortal fox passed by here and saw that there should be mountains and waters here, it was a good place to live and work in peace and contentment, and it should not be abandoned like this. He found this half-human and half-beast monster with his own spells. The immortal fox knew this monster, it was not a monster, it was a hundred-year-old zombie, and the wisdom of this monster was very high, and its mana should not be underestimated. In this way, the immortal fox used his life's cultivation to fight against this drought for three days and three nights. Finally, this drought was removed. The immortal fox slept and compared himself because his cultivation base was exhausted.

After Fox Immortal's death, his real body turned into dust and merged into this barren land, restoring life here. After growing precious medicinal materials, there are many sheep whisker grass everywhere. This sheep whisker grass is medicine and tea, and it can not only raise livestock, but also cure diseases. Usually, drinking tea with it can also prolong life, so most people in this town live longer.

Fox Immortal also became immortal because of his kindness and virtue. Later, this town was named Yangxu Town anonymously.
