The No.1 Undercover in the Immortal World - Chapter 807 - 313: Crystal Coffin

Lin Qi transmigrates to a world of immortals. In this world, there are sword immortals who can behead a person from a thousand miles away, peerless great demons who burn mountains and boil the seas, and ancient gods and devils who can divine the heavenly secrets.

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.

Sumi has always despised the world she lives in—one filled with greed, deceit, and pain. Trapped in a miserable life with a dead-end job and mounting debt, she sees no escape.

In a desperate act, she takes her own life—only to awaken in the darkness and found out that her wish has been granted she is no longer human she finds herself in the most unexpected form… a seed of a flower and she was in the world which she only knows in game and stories. a world where creature like demon, monster and things like magic and spells exist and she is going to live her second life… as a flower.

Shi Qing Xia is practically an angel.

Kind, sweet-hearted, and good at her studies, she was admitted to the top university in Taipei.

However, the living expenses for the metropolitan city were far greater than she had ever imagined, so she started to work as a private tutor for wealthy families to make ends meet.

On her first day of work, she met Zhao Yi Bo and Zhao Yi Xuan, a pair of neglected 16-year-old genius twins whose prosperous and wealthy parents heartlessly abandoned in Taiwan. Shi Qing Xia found them to be gentle, compassionate, friendly, clever, mysterious, pitiful and attractive.

But appearances can be very deceiving…

Because behind those sweet smiles…

Deeply twisted and cruel demons lurked, waiting to rip apart the wings of this angel, condemning her to an eternity of conflicted bittersweet suffering — a rollercoaster ride of a heart-wrenching, twisted, and tragic romance more extreme than what someone so innocent could possibly imagine.
