'Flip' 'flip' 'flip'

The sound of pages being turn resound in the quiet room, Jay lying on the bed is flipping through a book made by the system, the catalogue listing ability and item for purchase.

The book look thin, but the pages are seemingly infinite, Jay have been turn pages for almost an hour now.

With 5 billion in his possession, he was looking for something to boost his power. At first he confident ask the system for the most expensive ability, but the he despair at the string of zero that follow it so he can only dejected look at it before skipping.

Limiting thing that worth 5 billion or less, he look through the list before deciding on four of the numerous item.

With all this power, there few being capable of facing him in a head on fight anymore. The only remaining ones on Earth that should be able to threaten him would be the Ancient One using the Time Stone.

And unless a cosmic level being appear he will be relatively safe, but it the Marvel Universe they aren't that rare, he would still have some caution when dealing in outer space.

As he start exchange the items one by one, Gate of Babylon appear as a short sword shape like a key, when holding it the instruction came to his mind.

He slightly pushes it out, a golden ripple appears in midair and as he twist the key, his mind magically link to a new space, containing countless treasure and riches. Just the gold alone is enough to fill a stadium and that just a fraction, too bad the money make by exchanging item from the system can't be used to purchase item from the shop.

Then Accelerator, when trade for it, it was as if a new door is open to him, various force become clear to him and with a thought he can control them.

Picking up a mug and throwing it then suddenly in midair the mug stop and return back to his hand with incredible speed. Just before it touches his hand all the velocity disappear and it gently fall into his grasp.

With God Hand: The Twelve Labors, his body like covered in a armor there is no visible difference but he try using a sword from Gate of Babylon to cut his hand, the C rank Noble Phantasm just harmless bounce of his hand.

And when tried with A rank Noble Phantasm the cut hand began to heal itself and in about 10 second the cut in his hand is gone without a single scar.

Although there is also the ability to resurrect he has no plan on dying to just find out. He ain’t no masochist!

The change bought by Authority is even more invisible, there was no feeling at all. So he decided to test it on a nearby passing cockroach.

"Stop"

With his word, the cockroach froze, not moving. Jay walks around it marvel at the ability, and when he tries to order it to act natural, it weirdly didn't move at all.

Using his x-ray he found that, the cockroach heart has stopped!

Um... My sorry mister roach, may you rest in heaven.
