He had just graduated from high school and planned to deliver food over the summer to earn some pocket money. Who could have guessed that spiritual qi would revive across the world? While delivering food, Lin Feng ended up in a remote wilderness. On his way back to the city, he ran into a terrifying monster. Just as his life was on the line... 【Ding! Noble Earth bloodline detected. All-Purpose System activated.】 Lin Feng was overjoyed. After slaying the monster, he continued his summer job, while also searching the city for signs of monsters.

Facing the invasions from other worlds, Lin Feng gave a helpless smile. “So you've all got your eyes on Blue Star, huh? Then get ready to become vassal worlds!”
