I Became My Novel Character After the Apocalypse

Vale Gilstar had just finished his first novel, The Sword Demon's Reincarnation, when the disaster struck. A massive earthquake shook his home, and a mysterious voice announced the advent of the apocalypse. [Initiating awakening...] [Finding passion. Prioritizing...] On the verge of his consciousness, he heard of the awakening of the system. With Earth transformed into a chaotic battleground where monsters roamed, Vale discovered he had become the protagonist of his own finished story. "I-I can't believe it... I... have become the protagonist of my book." Now, he had to write his own story in the new world and put it into action. *** I am back with a new story. I finally managed to deal with everything I have IRL. Those who like my old novel 'The Author is an Extra, the MC is a Reincarnator' will surely like this too. I hope.
