MTL - Mr Fu, I Really Love You - Chapter 1271 Don't follow me anymore.

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”.

Fortunately for Su Bai, he had awakened the Divine-grade Simplification System. With the system, growing a beast was as easy as it could get. “Lightning Rat detected. The evolution path has been simplified. Plugged in. Evolution points +1, +1, +1…”

“Bubble Turtle detected. The evolution path has been simplified. Shower. Evolution points +1, +1, +1…” “Flame Cat detected. The evolution path has been simplified. Sunbath. Evolution points +1, +1, +1…” A few years later, Su Bai, the Divine Beastmaster accepted an interview. “Mr. Su, can you tell us how you achieved your success?” “I spend my time growing my beasts when other people are showering or sunbathing.”
