Hello, Mr. Major General - Chapter 3: Guardian

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

In the Bog forest, dangers were in every corner. During the nighttime, the thick white mist blinded the eyes and the chilling air froze you to the bones. Once morning arrived, thousands of ferocious mutated animals as big as the hills roamed for prey.

Among them lived the weakest species on the Meer Continent, the Monster Species. They only survived with their tough bodies in the midst of a world ruled by magic power.

To the mage, they were simply pests that were easy to be exterminated.

To avoid the eyes of the mana rulers, they had to hide in secluded places; in the caves shrouded by shadows or in the dark underground where filth was brimming. But, continuing to hide was not a solution.

When warbeasts sharpened their claws, elves polished their weapons, humans feasted on their greed, and demons searched for prey with their thirst, an orc named Moku was born.

Moku was a world MMA champion who transmigrated into the body of an orc in the magical world. He had always dreamed of possessing superpowers; being able to jump beyond the clouds, shattering the mountains in one hit and running faster than sound.

Moku dreamed of having these powers. He used rituals, magical lore, and all the things that were considered myths and fairy tales in his home world to make him and his tribe stronger.

A promise was deeply engraved by him. One day, he would bring the war to those who underestimated them.

Yun Luo Feng, Hua Xia Medicial School’s genius, died from an accident and her soul attached to Long Xia mainland’s General family’s useless eldest miss.

This waste of an eldest miss not only can’t read or practice martial arts, but is big chested, has no brain, is arrogant and self-willed.

Since having the crown prince as a perfect fiance isn’t enough, she actually snatched a pretty boy in public, leading to the crown prince annulling the marriage.

But she couldn’t stand the annulment and hanged herself.

Opening her eyes again, she is no longer the previous useless miss.

She contracted a God’s puppet and carries a spiritual space. With wonderful hands that can rejuvenate and medical skills that overturn the world!

Both the the royal descendants and nobles above and the merchants below, all compete to curry her favor. Even His Royal Highness, the crown prince,who previously broke the engagement, came knocking on the door wanting to reconcile.

In regard to this, a mysterious man finally couldn’t endure: “Whoever dares to come and harass my woman, let them come but never return!”
