Acquired the Scam Rune in the Academy - Chapter 250

Suddenly a high school student Subaru Natsuki has been summoned to another world on the way back from the convenience store. With the biggest crisis of his life being summoned to another world and no sign of the one who summoned him things become worse when he is attacked.

“Devouring Lifespan to grow stronger!!”When Ricky Stormwind—a washed-up office worker—drank himself to death, he expected eternal nothingness. Instead, he awoke in a new world… as a mosquito.Weak as an ant. Fragile as a piece of paper. Prey to everything.But this world is no ordinary one. Magic, monsters, and powerful beings dominate the land, with ruthless forces waging war for supremacy. And Ricky? He possesses a terrifying ability—he can drain lifespan from any living creature and use it to evolve.A single bite can grant him hours. A feast?..... Years!!Now, in a forest filled with predators and beside a village on the brink of destruction, Ricky must climb the evolutionary ladder—from insignificant pest to a calamity that could devour the world itself.But when his first real meal triggers a mass sacrifice, the world mistakes him for a rising Demon Lord. Bounties are placed on his head. Armies march to hunt him down. And lurking in the shadows, a forbidden power calls to him, promising a path beyond mere survival—one that could reshape reality itself.In a world where everything is prey to something greater, something horrendous… he will rise to become the apex.

Suddenly, a huge earthquake occurred all around the globe, throwing everyone into a desolate world.

The humans of the new world were primitive. They lived their lives facing all sorts of dangers every day, from hurricanes to attacks from huge beasts.

The humans that were brought to this world all received a totem and an egg.

Placing the totem on a certain land would turn the place into the person’s new tribe. Everyone could expand their tribes according to their strengths.

The eggs contained various beasts that would grow into humans’ most loyal companions. Humans would have to struggle to live in the desolate world with their companions and protect their own lands.

Just as Ye Chen was about to hatch his egg, he noticed he could read hidden hints.
