Another World Invasion? No Worries, I Put Money Into the System

[Low-morality protagonist + does whatever he wants + ruthless and decisive + no female lead (but there are women)]

Otherworldly forces keep invading, monsters appear with alarming frequency, and the apocalypse is coming!

To protect itself, the consciousness of Blue Star pours everything into creating a game, sending chosen players to repel the invasion and strengthen the world.

Fang Xiu, who transmigrated here as an unregistered outsider, naturally becomes a target and is selected.

Fortunately, the unlimited-funds first-purchase System he modified before coming here has come along with him.

He can claim a first-purchase gift pack in every game.

Zombie apocalypse: start with a miniature world in a pot, all the food and drink he needs, and a personal spatial domain.

Ancient-era power struggle: obtain a workshop that produces death soldiers, making it cheaper to turn people into them.

Daoist magic world: unlock a monster-slaying and leveling mode, then discuss with the final boss how to destroy the world.

Cultivation world: come with a Peach Blossom Divine Physique, maximize the efficiency of dual cultivation, and gain top-tier talent and comprehension with ease. The more wives I have, the stronger I get.

Game world: become an NPC, issue quests, fleece the players, and make trouble for my enemies.

In the real world, to promote justice and improve his standard of living, Fang Xiu decides to take down the head of a criminal syndicate and take the helm himself, so the people beneath him won't make the same mistakes again.

As for saving the world?

I already contributed more than enough by joining the game as an outsider. You still expect to get something for nothing?
