In the first few chapters time stops at a certain time at night then people get transported to a white room. Their first challenge is to defeat a monster. The second challenge they get transported to a forest but this time there are two people, one is a girl with orange hair with fire powers and the other is a guy with red hair and has healing powers.
The girl uses her fire powers to start a forest-fire (ending the challenge) and gains points for killing the zombies/skeletons.
It is not a manga it’s a manhua and I don't think it's being updated because I have not seen it on any recently updated or it’s finished because last time I read it was 3 years ago and the first time I read it was probably 2018 or 17ish.
I found it it’s called life howling if you see this you should check it out it is pretty good for when it was released and even write now when manhua, manhwa type books are popular.
