“Only when your brother is happy can you be happy.”

She committed all kinds of evil deeds to make him Emperor. However, Artezia’s devotion was repaid with betrayal. It was the Grand Duke Cedric, a righteous enemy, that gave her a hand of salvation at the threshold of death.

“Devise a plan.”
“…”
“I can’t think of anyone but you who can reverse this situation. Marquess Rosan.”
“…”
“Lend me your strength.”

There is no plan that can reverse the already declining power and save the fallen empire. However, there is a method. To turn back time before everything went wrong.

With tears of blood she sacrificed her body to an ancient magic. This time, she will not fall.

Artezia, who returned to the age of 18 before death, resolved to become a villainess for the Grand Duke Cedric.

In exchange for kneeling to the devil, the devil shall dirty her hands for you.

Unknown planets are connected, woven into shelters of life, and countless cosmic races explore, develop, multiply, and fight against the empty darkness.

The little nameless clan can gain power for hundreds of years, and the powerful clan of billions of years can disappear in an instant.

The human race started strong and went to the end.

No. 5 Broken Star, 732 Island Town, Wang Yu started his cultivation.

A few years later, the human race has bloomed in every corner of the world.

The god emperor looked back and was slightly surprised. “Cultivation is not just repetition over and over again. It will become natural after you have fully practiced. All of you are more talented and savvy than me. I believe I don’t need to say more about it.”

The arrogance of the human race looked at the figure of the god emperor floating away, and remained silent.

“Proficient, what is that…”
