MTL - Concealed and Blended: Fendai - Chapter 12

When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted.

Not only that, the Gu in his body could cultivate on their own.

[Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!]

[Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!]

[Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!]

[Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!]

[Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!]

“Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.

This script was originally supposed to be about a Scum Gong x Cheap Shou — the Scum Gong abuses the Cheap Shou, the Cheap Shou became hopelessly apathetic, the Scum Gong became a Cheap Gong, and the Cheap Shou abuses the Cheap Gong.

That should have been the case!!!!!

But the script began to unfold—-

The Scum Gong was reborn to the past, and encountered the Cheap Shou who also got reborn.

The Scum Gong was horrified to discover that the Cheap Shou had changed his job and became a beast-like, ruthless, blackened Gong, ahhhhh help!

The f*cking miserable Scum Gong was taken and defiled, then defiled and taken, then after being taken from the front he was taken from the back, and finally he was taken into a loyal dog, sensual, tsundere Shou!

The tale of Oliver.
An orphan boy from a Mine, in 19th century Europe, filled with Magic.

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
