Becoming the Demon Lord: Taming the Demon Queen Begins - Chapter 81: Noggin Knocker!

In this world, Planet Earth had undergone great changes and humanity is faced with extreme danger. Luckily, humans have something called the Heaven Dao software.

Lu Yuan was originally just a normal ordinary person, but one day he passed through it and became a day of destruction with a splendid reputation in the DC universe.

Doomsday does not refer to a single monster, but a terrifying legion from the technological civilization of Krypton.

But Doomsday is not a superman. In fact, it is a terrible biochemical weapon invented by the dead body of Kryptonian who got superhuman power and resurrected.

Lu Yuan became one of the doomsdays after just passing through, and entered the core of the sun for 100,000 years.

One day, Lu Yuan woke up, but when he flew back to Earth, he found that this place is no longer the Earth of the DC universe. I don’t know why he seems to have come to Marvel?

“Isn’t this invincible? Without kryptonite, I would be God.”

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”.

The bad news, at least for me, is that I died. The good news is that I was reincarnated into someone else's body who lives in a cult full of beautiful women... but this cult forbids love. Well, one can't have all the good things. I thought I was safe until the worst happened. A system appeared that told me that I would die if a girl didn't accept my confession within a month... I have to get out of that cult now.Every 10 days I upload 15 chapters at once on Patreon.
