Returning From Level 900 - Chapter 209 - Follow The Rules

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.

Shen Yansheng always thought that she didn’t like Lu Jingce until one day she heard that a certain group boss intended to marry his daughter to Lu Jingce. She was so angry that she couldn’t eat anything that night and locked herself in the room after returning home. When Lu Jingce came back in the evening, he took the key from the study, opened the door and entered her bedroom. He sat beside the bed, leaned over and kissed her to wake her from her sleep. She looked at him angrily, but he smiled happily and asked, “Jealous?”

Shen Yansheng and Lu Jingce have been falling in love all the time, mainly because she hadn’t figured out how to explain their relationship to her parents, which caused her parents to always think she was single, so they took the initiative to trick her into going on a blind date. But someone happened to have a dinner in that restaurant that day, and saw her and her blind date sitting at a table for dinner from a distance. She felt a gaze looking at her from behind, and when she turned her head, she met someone’s handsome face that was half-smiling. That night, as soon as Shen Yansheng came home, she threw herself on someone, raised her hand and swore, “I can explain it!” Someone still had that half-smile and pinched her cheek, “The explanation is invalid.”
