Young was sent to hospital again for being injected with too much antibiotics. Quinn, Nell and Jane came for visiting. Uncle Frank told them that Cure-diseases demon saved Young and many sick people on the hospital via injecting antibiotics. Young¡¯s being injected too much antibiotics happened in the second time injecting. Zoe and Windy looked for Cure-diseases demon, seeing the demon injecting with force. Zoe and Windy fought against the demon. Then Right-fin occurred. Zoe and Windy went back the base since they were not powerful enough as the enemy. The right-fin defeated the demon and brought it back to the Haigui castle, making it a demon by the giant mirror. Kearney explained to the teammates that the antibiotics given by the cure-diseases demon could kill the virus, but overdose would do harm to body. To confront the demon, the guards carried out special training to avoid the baseball, which could improve the speed and flexibility. Young woke up and insisted in joining the battle. Uncle Frank told Young why he couldn¡¯t join the battle, and their relationship was restored. The trained five guards avoided the syringe attack of the demon and blew him successfully. The guards were celebrating the victory. Young was peeping and left alone.
