I Heard Reincarnation Holds the Truth

On his way home, Chu Yi saw the seventh reincarnation gate and encountered Bai Ye, who had just emerged from it. After that, Chu Yi began noticing all sorts of strange things. Then one day, a close friend suddenly showed up in a panic, begging him to help find his girlfriend.

To uncover the truth, Chu Yi sought Bai Ye out again. It turned out that everyone who had disappeared had been swallowed by the world inside the reincarnation gate. Only those who followed its designated rules could make it out alive. But what Chu Yi hadn't expected was that the reincarnation gate had set its sights on him long ago...

So

Chu Yi (flipping his hair) declared: Has the Ghostface Gate got a crush on me? Sigh, being too handsome really is a sin.

Bai Ye (looking at him like he was an idiot) replied: You're overthinking it, kid. It just thinks you're too damn flirtatious and will corrupt society.
