Doomsday Descends: I Bring Ninja Techniques to the Whole World

After transmigrating to a parallel world rife with undercurrents and rampant with beasts,

Lin Ran awakens a Ninjutsu Sales System and opens a ninjutsu shop in this world.

He thought he would just make some money and admire the flowers, but right from the start, he learned the C-rank ninjutsu Fire Release: Great Fireball Technique!

And things got even more outrageous from there:

Lin Ran thought making money was too slow, so he founded a ninjutsu tournament and obtained Wood Release: Nativity of a World of Trees!

Lin Ran thought humanity's attack methods were too limited, so he began teaching people about ninjutsu and obtained Lightning Release: Kirin!

Lin Ran thought the alliance was extremely unstable, so he created a new alliance and obtained Shinra Tensei!

Lin Ran thought there were too many beasts, destabilizing the human economy, so he led humanity to wipe them out. To his surprise, he obtained Truth-Seeking Orbs!

Many years later, when people saw that terrifying crimson blood moon in the sky, everyone was dumbfounded:

"We told you to sell ninjutsu, and now you're going to become the God of Ninjutsu?"
