A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world

A turn over of the geocentric Yanlong living in the core of the earth.

It completely destroyed the human scientific and technological civilization that had been developed for thousands of years.

With the return of extraordinary power, the emergence of extraordinary creatures, the fusion of multi-dimensional planes.

Human civilization has entered the era of beast-fighting.

At the core of the earth star, the terrifying head of the earth core Yanlong sticks out.

Above the floating clouds, the Wuhai Phoenix Bird revealed its slender and gorgeous tail feathers.

At the bottom of the Dead Sea, the Vast Sea Dragon Whale swings the body of Pang Ruo Land.

At the end of the earth, the devil wolf chases the blazing sun that never goes out.

Ordinary people who were born in the old era and grew up in the new era were reborn ten years ago.

Unpredictable and able to see through the potential of the beasts, he started a road to collect the beasts of the gods.

All stories have to start from that late autumn ten years ago.
