My Dragon-Slaying Mentor Is Called Lu Shanyan

(Dragon clan fan) Ji Yuchen had a dream recently. In the dream, he went to a German city called Hamburg in 1900 from the perspective of another person, and fought life and death with a group of things called "Undead". When he woke up, the protagonist whose memory he had spied on also came to him. He calls himself "Lu Shanyan" and talks about "overthrowing the dragon throne", "secret party" and "dragon clan" which are incomprehensible. "Dragon? You're laughing so hard, I'm still a little dragon... Wait, I'm really a little dragon?!" ... Half a year later, on the dragon-slaying battlefield, looking at the graceful young man, Principal Angers couldn't help but recall the distant time when he first met Meniek, Lu Shanyan and others.
