The Price of Speedrunning Is a Shura Field

A story in the same vein as The Strength-Obsessed Player Is Strong and Shameless, and The Price of a Speedrun Is a Shura Field. I just threw this blurb together; I might change it later once the story gets underway.

Shura field + leveling up + shameless protagonist

A shameless player is chosen by the System to play a cannon-fodder role in countless worlds, guiding the protagonists through hardships and toward successful lives.

The shameless player: ...What a hassle. Can't I just get it all done at once? I only want to speedrun.

So the shameless player chooses to merge the worldlines, taking on missions for the favored sons of heaven from all four worlds at once.

The crown prince of the Galactic Empire was born blind in his left eye and bullied by his elder brother. No problem: the shameless player gets hold of his elder brother's eye and gives it to the crown prince.

A former pirate leader was betrayed by his subordinates and stripped of his freedom. No problem: of course the shameless player helps the pirate leader take revenge.

A monster controlled by a mad scientist suffers immense pain from the drugs in its body. No problem: the shameless player has better medicine.

But...

Who is the enemy threatening to destroy the crown prince's homeland while he's still in swaddling clothes?

Who is the enemy who betrayed the pirate leader and took his left eye?

Who invented the most crucial technology used to modify the monster?

Who could it be? Who could it be? Who could it be?

So hard to guess!

The shameless player keeps his secret identity under wraps. He only wants to speedrun and have a good time. Why has a shura field come looking for him?
