In the unpublished article, Xiao Zhi, a novice trainer, got a Pikachu from Dr. Damu. He was reluctant and moody and didn't like to enter the elf ball. Xiao Zhi left his hometown and started a trip to Guandu. After winning Pikachu's trust, Xiao Zhi began a journey of seriously challenging Taoist temples around the world and joined the Baokemeng Alliance.

With Xiao Zhi, there are two mentors-Xiao Gang and Xiao Xia. After attending the timely meeting, Xiao Zhi was entrusted by Dr. Damu to go to Oran Islands to retrieve the GS ball from Prof. Ivy, and Xiao Gang stayed in Prof. Ivy for the time being. During the trip, Xiao Zhi joined the Orange Alliance, met Xiao Jian, an observer of Baokemeng, and walked with him.

After returning to Zhenxin Town, Dr. Damu couldn't figure out how to open the GS ball, so he left Xiao Jian as an assistant and sent Xiao Zhi, Xiao Xia and Xiaogang to the downtown area to give the GS ball to Mr. Steel in Guipi Town.
