Natural disasters struck one after another, monsters ran rampant, and order collapsed overnight.

Following the devastating floods, a freezing -70°C followed.

Then, the temperature soared to 60°C, the world dried up, water scarce, and the world seemed like a giant furnace.

Just as the survivors finally survived the calamity, celebrating their survival,

an unprecedented earthquake destroyed all traces of human civilization.

The survivors exclaimed: “The sky has fallen!”

But this was only the beginning.

A terrifying scarlet plague transformed the dead into prey-seeking zombies, and mutated monsters spread across every corner of the world.

Humanity quietly plummeted from the top of the food chain to a preyable existence.

On the eve of this despairing apocalypse, Jiang Yu was bitten by the turtle he had raised for twenty years, awakening his special powers and activating his Doomsday Enhancement System.

When the palm-sized turtle transformed into a mythical behemoth with a shell covering thousands of square kilometers, and a snake actually grew on its back, Jiang Yu was stunned.

”I named you Xuanwu, and you really are Xuanwu!"

After transmigrating into a world of Beast Tamers, Fang Ran found himself scammed and tricked into contracting a crippled angel.

But because of this, he awakened a god-tier talent — Advance Credit — allowing him to enjoy the results first and fill in the process later!

While everyone else was grinding day and night to learn new skills, Fang Ran’s angel had already mastered them all.

While everyone else was racking their brains trying to evolve their beasts, Fang Ran’s angel had already ascended into a divine being.

Classmate: “He’s way too hardworking. He keeps training even after mastering all the skills!”

Campus Belle: “When it comes to hard work, I can’t compare to Fang Ran. Even my beast can’t compare to his!”

Years later, someone asked Fang Ran the secret to his success.

He simply smiled and said, “Just reviewing the basics, over and over.”

[Beast Girl + Superpower + Passionate Blood + Decisive Killing]

This is a world of beast girls. Girls can awaken and become beast girls with different superpowers when they turn 18. Boys can awaken and become beast tamers, sign contracts with beast girls and fight.

Xu Que traveled through time and happened to see his class beauty girlfriend awakening into an S-class beast girl, and she cruelly broke up with him.

At the critical moment, Xu Que awakened the god-level beastmaster and activated an extremely terrifying god-level talent.

[Insightful Eyes]: Can detect supernatural powers, physical conditions, and even defects in all things.

[Source of Evolution]: Help the contracted beast girl evolve in level and ability while receiving a lot of feedback.

[God of Beasts]: There is no limit to the number of beast girls that can be contracted.

…

When his girlfriend, the most beautiful girl in class, wanted to come back and lick his ass, Xu Que decisively signed a contract with the F-rank school beauty beast girl!

While everyone was laughing at Xu Que for being deceived by beauty, one F-level school beauties grew up step by step into SSS-level beast girls under Xu Que's training!

When a tide of ferocious beasts engulfed the city, nine blood moons rose into the sky.

The gluttonous god devoured the world, the frost queen froze time and space, the fallen angels tore the dimension apart, and the mechanical girl's nuclear explosion wiped out the world...

The people sitting in the ruins looked at Xu Que who was walking in the air, and then they realized:

Those world-destroying SSS-level beast gods all had collars given by Xu Que tied around their necks!

[Wife] + [Superpower] + [School Beauty] + [Multiple Heroines]

After the catastrophe, the world was reshaped, strange beasts roared on the ruins, and human civilization struggled to survive in the cracks.

In troubled times, population is the foundation, and everyone shoulders the mission of reproduction! The more capable a person is, the more obligated he is to take care of more women and give birth to more offspring.

Gu Chen, who was about to turn 21, had reached the deadline for compulsory marriage in Longguo! If he did not register for marriage, the state would forcibly assign him a wife.

How could a poor Gu Chen be liked by any girl? He could only accept the assignment. As a result, his sister's school beauty classmate became his "legal wife".

Fortunately, the system was activated, and with this opportunity, Gu Chen's life changed dramatically...
