Horror: I Took a Vengeful Ghost as My Big Sister

[Female ghost lead + no romance = no female lead? + horror game + supernatural thrills + ghost mastery + leveling up and growing stronger]

Horror strikes, terror descends!

This is a parallel world.

Here, some people suddenly find a countdown appearing on their arms for no apparent reason!

When the countdown ends, they are transported to a place called Heavenly City.

Heavenly City is nothing like its name suggests.

Because it is overrun by vicious ghosts!!!

In the real world, people discover that the countdowns come in two colors, black and white.

But those who have never entered Heavenly City don't know what the difference is.

Until one day, Lu Li suddenly discovers a countdown on his own arm.

But his countdown is a strange shade of red…
