As Xie Lan suggested, the disciples training in alchemy – Li Tian, Lei Ling, and You Rou, learned martial arts while the disciples training in martial arts – Fei Yin, Feng Mo, and Lei Qing, learned alchemy. As the one in between – or, actually, have both worlds, Cheng Sheng was personally trained by Xie Lan while the six were under observation by Fan Wen.
Li Tian is average in martial arts, so he only needs to improve his martial arts. Meanwhile, Lei Ling and You Rou are clumsy in using their sword. Initially, Xie Lan –as their sect leader, has given them their sword. But, Lei Ling and You Rou neglected their sword and practiced alchemy. They only use their sword during Fan Wen's martial arts classes. Even their fellow disciples are better than them. In short, the two of them are at the bottom of the Martial Arts ranking of their sect.
