Global Class Change: A Divine-Class Hybrid of Mage and Assassin

[Power Fantasy + No Hiding My Strength + Everyone Gets a Class + Maids + Class Advancement + Ruthless + Invincible + Assassin + Summoner + Shadow Legion]

Games and reality merge, and countless portals and dungeons randomly appear around the world.

Humanity enters an era where everyone can change classes. Only by becoming a class-changer can you stand at the top of the world.

After transmigrating, the male protagonist gains a god-tier hidden class: Shadow Monarch.

He thinks it's a mage class focused on summoning, but it turns out he also has assassin skills!

What's more, his shadow summons are immortal and can level up without limit! They can also be resurrected endlessly!

Any damage he takes is transferred to his summons! As long as he has summons, he can never die!

From then on, he goes further and further down the path of dealing maximum damage!

What? Clearing a Nightmare-difficulty dungeon requires a team of sixteen? I can do it alone!

You think I'm by myself?

Sorry, I have a shadow legion of hundreds of millions, and every last one of them is max level!

Dungeon bosses? They all become my shadow summons!

You think I'm just a summoner?

Sorry, I'm an assassin too!

And, more than that, I'm the master of the Shadow World!
