In JJK With Naruto Powers - Chapter 15: System Store

Qin Lin was electrocuted by playing a nostalgic “Ranch Story” game, and suddenly gained the ability to enter the game. He also found that he could bring the watermelons grown in the game out of reality.

At first, he calculated that a pound of watermelon would sell for 2 yuan. As long as he sells 10,000 catties of watermelon seeds in the game, he can earn 20,000 yuan a day.

Later, he discovered that by upgrading pastures, he could obtain advanced crops beyond the world, raising livestock to obtain advanced livestock breeds that were far beyond the world, and building factories to obtain various formulas that were far beyond the world, and everything was different.

- Description from novelbuddy

This is a story about a badass,

“I am a benevolent god. If you worship me well, maybe I will save you… from the calamities I send.”Zayne was just an ordinary guy, when he was picked through a random draw to become a host of the God System. Having accepted the offer - could that even be considered a choice, when his soul would have been exterminated otherwise? - he was transported to a different world, tasked with gaining believers and growing his cult, earning points from their faith. Once he gained enough believers and points, he would be able to rise to a higher position in the Pantheon…However.A ‘life’ as a deity turned out to be far less glorious than he would have thought. Centuries later, he is still stuck in his first world. Fulfilling prayers day in and day out, as a mere consciousness floating in nothingness, alone with the system. He cannot rank up, he cannot move on, and he cannot even vent his frustration well, because he’s always short on points!And his believers are not even loyal, still worshiping other gods as well!In a moment of distraction, he makes a mistake, which initiates his descent.Not wanting to waste the points he has already spent, Zayne decides to wander the world for a while, posing as his own prophet, using this opportunity to spread his faith… And more importantly, vent all his pent-up anger, and have fun along the way!Randomly doing whatever he wants, he accidentally discovers a path he could take as a god: sending calamities, and then rescuing people from them - of course as long as they pray!And so his journey to the top finally begins.

– The planet [Earth] has entered the abnormal state [Apocalypse].
