I recommend the novel "The Sword Immortal System at the Beginning of the Apocalypse". The story was about the apocalypse sweeping across the world. The protagonist, Han Feng, awakened the Immortal God System and transformed into a sword immortal. With a flying sword, he killed through the apocalypse, killed zombies, killed monsters, collected mutated beasts, and obtained treasures. Killing a small zombie with one sword, killing monsters could also gain attributes and strengthen oneself, making him invincible at the beginning. In this world where zombies were rampant, it was very interesting to see the main character fighting monsters. I hope you like this fairy's recommendation. Muah ~😗
