MTL - The Return of Cambrian Period - Chapter 271 New world

Lee Jin Woo once lived a dismal life.
He lived pitifully on a day to day basis in his five-pyeon studio filled with mold.

Then, one day, he died in a sudden fire.

When he wakes up, he finds himself inside a novel.
But there’s just one issue…
He had become the novel’s villain!

Wang Yi gets a key, opening a door in 2022 will lead to 1982, and opening a door in 1982 will return to 2022.

Two very different great eras appeared before him:

Abundant dietary protection, developed industrial products, miraculous medicines, and explosive information, this is 2022.

Simple folk customs, rich wild resources, scattered antiques, and treasures of the age, this is 1982.

Traveling between these two eras, Wang Yi didn’t think much of it, he just wanted to live a good life.

A series of nine stars occurred here, and various creatures violently mutated, killing the former overlords – humans crazily.

Thermal weapons are no longer humanity’s trump card.

Fortunately, mutations have also occurred in humans.

Human beings will awaken their bloodline at a specific time and gain the inherited power of various ferocious beasts.

And Xu Mo, who obtained the system, was even more outrageous.

He awakened the bloodline of the ten ancient beasts and led mankind to regain its dominance! !
