I Caught Ghosts and Sealed Demons in the Tang Dynasty

Demons are rampant and people are suffering. Only through self-improvement can we continue to thrive. Cui Yu traveled through the Tang Dynasty in another world and became a preparatory member of Jing'antai. This place is full of strange things, martial arts, immortal magic, and demons. Fortunately, an eleven-story black and yellow pagoda appeared in his mind, revealing its traces, breaking magic, collecting and refining it, allowing Cui Yu to kill the demons and obtain miraculous elixirs and magic powers. Snort! He's so talented, but he dares to do whatever he wants, he's so... Bold!
