Broken Sword Cuts Fate

In an imaginary fantasy world, a boy and a girl practicing in the same sect had a youthful and hazy love affair, but were unexpectedly interrupted when they were about to confess their love. He rescued the girl who fell into the water, but found that murderous intent was coming quietly. Faced with the relentless pursuit of monsters, he uses the power of wind, sword shadow, purple lightning, transformation, and magic to fight his opponents with all kinds of martial arts. But he can't escape death after all? If you kill me and escape, will you be able to escape with wings? Can the teenagers escape? "Senior brother?" "Senior Brother Lu?" "Brother Lu?" "Junior Brother Lu?" "Don't worry, leave it to me. I will definitely take everyone back safely, even if only one person and one sword are left." "Senior brother, please don't mess around!" "Of course, what should be the question,... Uh, probably?" This is a short story of about 50,000 words (it should be easy to read) and it is also the prologue and prequel to my original novel.
