800 years ago, 3000 dimensional gates opened across the entire world. In that moment, it was as if 3000 different colored eyes opened across the world as hordes of monsters swarmed out of these gates like tears.

Some could destroy city walls with one strike; They had bodies the size of a giant and fed on humans

Some latched onto humans, absorbing their bodies’ nutrients and enslaving humans

Lucas is a homeless teenager who had everything taken away from him— his family, his home, his childhood. Even worse, he was born without any abilities in a world where humans with superpowers dominate.

All of that would change when a new dungeon appears before Lucas.

Thinking that it was a sign the gods have given him— that he should just give up and end himself, Lucas enters this dungeon without hesitation while expecting death.

However, inside the dungeon was not the end like Lucas had expected.

Instead, it was the beginning of his life of carnage.

Wielding the power of a «Hero», Lucas begins his journey of vengeance on the world that stole everything from him.

Ning Bei worked hard to get into Lincheng University and came to the city Nan Xia was in. Nan Xia introduced him to others as: “Her younger brother.”

After returning home, Ning Bei was lying on the floor like a stray dog.

His brother Ning Nan couldn’t look at his depressed face anymore, so he gave him a kick: “Now you know that acting like a dog will end badly?”

Ning Bei closed his eyes, and said in a cold voice, “Never again.”

Ning Nan chuckled and was about to leave when the exclusive ringtone that Ning Bei set for Nan Xia suddenly rang in the room.

Under Ning Nan’s fiery gaze, Ning Bei lay on the ground for one extra second.

Then he quickly got up from the ground and ran to the phone.

Ning Nan: ?

Ning Bei: Scram.
