Choose the Devil Fruit Tree at the Beginning of the Apocalypse

In 4000 AD, alien civilization invaded and Aquamarine Star was destroyed. Chu Feng, the son of King Qi of Emperor City, traveled back to 500 years ago from the moment of destruction. At that time, Water Blue Star was still a three-legged alliance of humans, zombies and monsters. Recalling the terrifying extraterrestrial civilization, Chu Feng was still full of despair for the future. However, when he was disheartened, he was surprised to get the Doomsday King system, and he chose the Devil Fruit tree at the beginning, which was already full of Devil Fruits. Looking at the colorful devil fruits, Chu Feng couldn't help but said with great enthusiasm: "You have zombie legions and monster beast legions, foreign civilizations have terrifying armor legions, and I have a demon legion!"
