Bone Alchemist: Necromancer of The Aberrations - Chapter 23: Where am I?

Chu Xuan transmigrated to a fantasy world and became the young master of a powerful family. He was rebuked for misbehaving just because he sneezed during a banquet. As punishment, he was banished from the ancestral mansion and was relocated to a remote residence.

He did not mind the punishment at all. He just needed a spot that could allow him to be a shut-in. With the system that would allow him to grow stronger by being a shut-in, the longer he stayed indoors, the more powerful he became.

After being a shut-in for a day, he was rewarded with the Indestructible Body Technique.

After being a shut-in for a month, he was rewarded with the Immovable Mountain Technique.

After being a shut-in for a year, he was rewarded with the Yuxu Celestial Scripture and 100 years of cultivation.

After being a shut-in for 10 years, he was rewarded with the Chaotic Indestructible Body and the Bell of Chaos.

…

Chu Xuan declared, “No one can make me leave my home. I like being a shut-in!”

He is the emperor of the business world. Rumor has it that he was fond of men and because of this, Song Wen Xin agreed to marry him.

After their marriage, he proved to her that he has the ability of a normal man!

“You are not allowed to hide when fulfilling the obligation of husband and wife. You are also not allowed to refuse the gifts that I send you. And, when you take the initiative to come to me… you are not allowed to stop!” He ordered her overbearingly.

Song Wen Xin immediately said: “In your dreams!”

He laughed enigmatically: “What a coincidence! I’m best at making a dream into a reality!”

He dotes on her, dotes on her with no bottom line at all…

The consciousness of a Great Magus suddenly returned to his original body on earth, just before he transmigrated into the magic world.

Nothing has changed, it's still the same earth.

However, when he looked at earth once more as a former great magus, he discovered earth was not as simple as he knew it to be.

Hidden magus, legendary races such as vampires and werewolves, they do exist, ruling the world through the shadows.

Faced with a former great magus, who possessed as many spells as libraries, would the earth that had been ruled by a few people be able to remain calm?
