Revenge: It Begins When My Sister's Blood Is Drained

The protagonist is only out for revenge. He's not a psychopath. If you think he'll kill everyone he meets, read with caution.

Since justice came too late, the protagonist decided to get there first.

[Thrilling payback + revenge + face-slapping + morally ambiguous + secrets of the underground caves]

I'd rather betray the whole world! You all deserve to die.

“There's something suspicious about your sister's death.”

As soon as the woman finished speaking, Teng Zhe bristled like a wild beast, eyes wide as he glared at her.

“What~ did~ you~ say!”

The protagonist, Teng Zhe, risked his life to obtain a blood pearl, but still failed to save his younger sister.

He never expected her death to be part of a conspiracy.

Her blood had been drained just to save a beast???

The world is unjust, so I'll become an avenger.

You want to live? Sorry, why should I let you?

“Little sister, not one of the people who hurt you will get away. I'll fulfill your wish, too.”

But all kinds of strange incidents cropped up during his revenge. Were the underground caves gateways to other worlds? Had strange changes begun appearing in human bodies?

The Avenger System upgraded, and the close-combat fighter gained the power to control the elements: fire?? ice?? gale?? thunder!!

See how Teng Zhe uncovers the source of the bizarre virus, travels through underground caves and into other worlds, and slaughters all manner of demons, monsters, supernatural beings, evil spirits, and false gods.
