Once in time, Qiao Xu, a modern otaku who was actually twenty years old, traveled to the mountains to be an apprentice to an expert. When she was confused, the master took her down the mountain to travel and level up to fight monsters. However, Xiao Qiao was really unable to hold herself up the wall. Apart from being a drag and running fast, she had no other use. Fortunately, the master did not dislike him and taught him tirelessly. Qiao Xu's skills in practicing talismans and poisoning were quite good, so he was not a complete useless person.
