How is this Dragon so Popular?

Chen Wen, suffering from a cong**ital disease, could only lie on the hospital bed his entire life. At 20 years old, his life came to an end. Before he left, he looked at the small world outside the window, his eyes filled with longing and unwillingness. When he woke up again, he found himself transformed into a black dragon. Dragons are powerful and have long lifespans. He decided that in this life, he would travel to every corner of the world. … Many years later. “Have you heard? The Church’s Holy Knight Legion and the Magicians’ Guild joined forces to attack the black dragon but failed, suffering heavy losses!” “What! Are there many black dragons? Is the Dragon Clan making a comeback?” “No, no, there’s only one black dragon.” “One black dragon? The Holy Knight Legion and the Magicians’ Guild joined forces and still lost?” “Of course! I heard that black dragon was wearing demon-repelling armor and wielding a large wolf-tooth club; both are equipment comparable to sacred artifacts.” “How come I heard that black dragon defeated the Holy Knight Legion and the Magicians’ Guild using magic.” “Don’t be ridiculous! Black dragons aren’t people, how could they wear armor and wield weapons? You’re even more ridiculous, using magic! With the single-mindedness of the Dragon Clan, can they learn magic?” “You know what, that black dragon is indeed popular among people.”
