Contract marriage: His Sweet Wife and Cutest Twin Babies - Chapter 158

Everyone has a system they just need to meet hidden conditions to unlock it. A blacksmith system may unlock after a human walks by a forge. A master mage may unlock a system after attempting to control the mana in their body. Even something as simple as kicking a rock at a bucket can unlock the marksman system a unique system allowing for perfect accuracy. But what happens when someone reaches the age of fifteen and hasn’t unlocked their system? Walker is about to find out, time is ticking and he doesn’t want to live out his life as an ordinary human; he has dreams you know!

Lin Mu was pushed down the cliff, but he did not die and arrived to a magical world instead.

A huge python with wings and can fly, alright, just think it as the legendary Mayan Snake God;

A gigantic centipede that can fly in the sky, alright, he kinda seen it before in ‘Journey to the West’;

A mighty big wolf with a body as humongous as an elephant, en, just think it as a mutant;

….

Although the animals in front of him were a little strange, they are still animals but why did all of you suddenly turned into humans? Coming across wild beasts, Lin Mu still can accept it, but coming across ‘*yaojins’, Lin Mu became . . . . . . excited instead. What? You guys are the infamous drifter beastmen? I don’t know anything about that. You guys did a lot of heinous crimes? I don’t see that either.

And so, Lin Mu began a hard but satisfying life of building a home in a another world.

*Yaojin/妖精 doesn’t have a proper English equivalent word. The nearest meaning would be supernatural being or Yokai (Japanese).
