MTL - I Wield a Sword at Hogwarts - Chapter 30

In less than an instant the world as we knew it was at its end. That’s right. The Apocalypse. In a single blink Zombies appeared and mutated monsters began to rampage all throughout the world. Now it was the human species turn to fight for survival and planetary dominance! On the same day that the world descends into chaos we meet Yue Zhong. Initially only hoping to get to his friends and escape to a refugee camp our protagonist sets out, inadvertently building a team along the way. After a series of fortuitous events and a few serious hunches our hero decides it’s time to do more than just survive! Yue Zhong begins to form the foundations of an enormous survival plan… before he suddenly discovers that he has only gotten over the first hurdle….

Unbeknownst to Yue Zhong and company, the world outside of China is mostly a wasteland! Country sized swathes of nuclear radiation and an extreme shortage of supplies in the world after the nuclear explosions was quickly becoming the “norm”. Mutants, Evolved animals and what’s worse, intelligent out of control dinosaurs had quickly appeared and claimed their own sections of the planet. There were several innately powerful Evolved races which appeared that were more than 10 times stronger than humans, nearly all of them possessing bodies impenetrable by normal bullets. The fabled orcs’ were another of these Evolved races, the leader of which had in fact enslaved many of the remaining human beings. Unceremoniously exposed to such a cold and heartless new world, Yue Zhong is faced with a choice: Find a deep dark hole and hope it goes back to “normal”? Or overcome all obstacles and struggle towards Evolution!!!

Xuanyuan was reborn into a strange new world where training to be a Xian was a cornerstone. There was however something ancient dwelling inside his body. He could now devour all of creation…

This is the journey of an ordinary boy and his transformation into the supreme being that reigns over all existence! Everywhere he went, he could not help but tie his fate with numerous women. It did not matter whether they were a goddess or a devil…
