One day, unfortunate news flew all the way to the Mage’s City. The mage, Solar Xing Ayra’s, entire family had been killed in an accident. Thus, he must now become the next Lord of the Solar family. The childhood home he returned to felt unfamiliar and strange. He barely managed to conduct a funeral with advisors that regarded him with suspicion. After fainting from various stressors, he woke up and… “Hello, Master. Nice to meet you!” ^o^ From now on, I’ll be the cute GM spirit fulfilling Master’s dreams: ‘Adventuring the world!’, ‘Fun estate management!’ I’m so happy to be with Master from now on, yay! “Enter a name ______” … What is this pebble-like spirit that calls me ‘Master’? No matter how you look at it–these level-up quests and these system windows…they were similar to a game’s user interface from his previous life. What is this… thing that seems more suited to modern civilization? Reminiscing on the games he had longed to play, Ayra worked hard on the quests. And, slowly, he also began exploring the territory. However, the territory… [D-234 days until the fall of the Solar estate.] “There are 234 days left till ruin…?” Alright, let’s start with the coronation ceremony. Things will work out somehow.

A genius schemer, creating an emperor!

“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.

“Please give me your hand in marriage. I’ll make you emperor.”

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

The doomsday fell upon the earth when a dragon coffin sealed under a snow mountain for ages shifted, and the civilization of gods and devils began. The whole universe turned into a fantastic new world where everyone could rise to the top through cultivation. A lucky young boy seized the opportunity, and started his journey to be an overlord in cultivation.
