Summoned Beasts? I Craft the Sun Ladder from the Start

When Ye Ren opens his eyes, he has transmigrated to another world where summoning reigns supreme, becoming an ordinary person without a summoning totem.

But the biological knowledge in his mind, along with his talent for handcrafting the Progenitor Virus, leaves Ye Ren astonished!

Now the entire world is about to be turned upside down!

A necromantic plague? Ordinary zombies infected with the T-Virus can crush them!

A Shadow Tiger King? One Hellhound infected with the G-Virus can wipe out an entire group!

When the Sinflame Dragon flies in from Dragon Island, a Tyrant that has undergone sixty-four evolutions punches it into a heap of minced meat!

Demon Cult Leader: "What the hell is this monster? It's even more terrifying than the Seven Deadly Sins I've raised!"

Holy Light Alliance: "An abomination! This is an abomination capable of destroying the world! We must act at once!"

Assassins' Guild: "Boss, are you selling your summoned beasts? That Hunter looks pretty useful!"
