The Seventh Calamity will be the End. And the only one who can stop it from happening is you, my friend.”With that said, the old man perished away into particles of light, leaving the world stunned as system windows popped up in front of all human lives.The world fell into havoc, while a grin crept onto Kai's face as his memories returned.Now the question begs to be answered...Which path will the Primordial Villain—The Survivor Of 6 Worlds—choose?***it's not a VRMMO or Litrpg story. just that the start of it somewhat resonates with those genres.***
