Shadow Monarch x The Novel's extra ( Solo leveling )

One day while coming from the PC I saw a small kid running for a ball on road and i saved that kid from truck and I died.
F#ck. The only regret is "I will not able to see Solo Leveling Anime " but when I opened my eyes I was in Novel's Extra world with Solo Leveling System.
But I didn't remembered this story. How I am going to survive?
