Tan Wenbin, who practiced with them, was so envious of their progress that he could almost drool. His companions were improving at a visible rate, but he only managed to improve his physical fitness.
Every night, the three would practice moves, starting with Tan Wenbin choosing one, and then the chosen one would quickly take him down, followed by the remaining two sparring.
The only thing that gave Tan Wenbin some confidence was when Xiao Yuan taught them three how to travel through the Underworld, he progressed the fastest.
Although Xiao Yuan forbade completing the last step of Underworld travel, Tan had mastered the preceding steps, while Run Sheng and Yin Meng learned it much slower.
Despite this, Tan Wenbin noticed something was amiss—that he'd often experience sleep paralysis during nights or during class naps.
After telling Xiao Yuan, Xiao Yuan said it was a side effect, and following sleep paralysis, Underworld practice must be paused for several days.
