Project BIOHUMAN was supposed to be a quiet project that tested to see if they could create superhuman beings. The Creator, Dr. Vang Chang created the Numbers, ten individuals who took the BIOHUMAN serum and came out different.

Countries caught wind of this and demanded the Creator to disperse the serum to strengthen the humans. The BIOHUMAN serum was shot into the sky and dispersed all over the world. Little did anyone know, it changed Earth and everything living on it. Plants, animals and humans were genetically changed forever.

25 years later, the Creator's son, Lee Seng Chang is a high school student without any Biohuman powers. The serum had given him almost no Dark Matter and only increased his overall human abilities to a super-Biohuman level. Even with that, the power standing only made him seen as the weakest amongst everyone.

Picked on because of his powerless status, Lee Seng was left by all of his friends and labeled powerless. He desperately tries to keep going with a smile on his face. Lee Seng one day gets an option from a man with a Fox mask.

“Awaken your power but at a huge price.”

Lee Seng takes the deal and watches as the world he knew quickly changes and isn't what it seems. Put under the pressures of his Father's status and his new profound power and changes, Lee Seng battles the demons within him and the unknown coming for him.

As a cultivator, Lan Tian never expected she'd been hurled back to the 1970s countryside!Suddenly stripped of her powers, she's surrounded by mud - brick houses and farmland. Facing farming to social quirks with no modern conveniences, she relies on her cultivator's wisdom and resilience.

People all say that the fourth daughter of the Marquis of Jing’an is really lucky. She is favored in the palace, has heirs and has a good family background. That is really a great thing! In fact, Shen Chuliu himself didn’t know how he got to this point.

It was like this at first. The concubine next to her was playing the piano and dancing. Shen Chuliu said that I was not a performer.

The concubine next to her was writing poems and painting, and Shen Chuliu said that I didn’t want to take the imperial examination. People laughed at her and said she was not favored. She smiled slightly and said, “I have a family background.”

The emperor really has no choice. If the concubine doesn’t come to please her, he still has to see her! Who said someone’s mother’s family is really awesome? Shen Chuliu really didn’t care. Those bastard relatives liked him so much that he started to let himself go as soon as he entered the palace.

It feels good to let go for a while, and it feels good to keep letting go. As a human being, the most important thing is to be comfortable. If you are too frustrated, even the emperor will not be able to use it!
