I Am A Wizard Who Can Travel Between Earth And The Other World - Chapter 12 - Team Y1: The Malice Beast Breeding Grounds

In this world, strong warriors are needed in order to conquer the hot crimson desert. The Pareia Tribal-Chief’s first-born son, named Yulian Provoke, routinely gallops through the stormy deserts alone. Only to find someone of destiny – an otherworldly man that would change his fate forever. This same young child who struggles to find purpose while embodying both ambition and revenge into his very own hands as he awaits that faithful day of confronting a particular person that was, supposedly, the culprit of his blood-mother’s death. At first, he was alone; but then after, he forms the RED STORM division – a group of powerful warriors at his command – in hopes of Conquering the Desert, braving towards those who oppose him, and bringing great fortune to his tribe.

Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth, was slightly different. People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel’s world, he was also given a mystical ability to grant systems to other people. Armed with his special ability, he slowly climbs up the power ladder by taking “taxes” from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.

I, the mighty Telepath Starlord, got banished into the mortal world. The days in the mortal world are much better than those in heaven! Everything is here — money, authority and most importantly stunning beauties! I am from a rich family. Yes, I am indeed wealthy now. The kind of wealth where you would not want to displease me. Domineering CEOs, military big shots, business geniuses, you name it — I know them all! I know everything you are thinking about. You can’t defeat me anyway, how are you going to go against me? A century in the mortal world is only equivalent to a hundred days in heaven.
As an urban banished immortal, I will enjoy the heck out of my time in the human world and a huge commotion would arise in heaven!
