Villain: My Younger Brother Is an Immortal Emperor

[Villain + invincible + the Immortal Emperor’s big brother + System...]

He transmigrated into a fantasy world of advanced martial arts, formed from the fusion of countless worlds, and became the cannon-fodder older brother of the protagonist, an Immortal Emperor.

At this point, there are seven days left before his younger brother witnesses the murder of the brother he has depended on since childhood and awakens his memories as an Immortal Emperor.

Fortunately, he awakened a System that can defy fate and change his future.

But why is it a villain System, huh?!

I can’t believe you, my foolish little brother!

Your big brother bullies you so his beloved older brother doesn’t end up dead!

So, my foolish little brother, hand over your Supreme Bone like a good boy!

Heh heh heh...
