83 System Upgrade?

Leo saw an image of the black-coloured stone on the mirror screen and could not help but feel like he had seen an oasis in the middle of a desert.

It was none other than the 'God stone' that could even make the Supreme Heroes go crazy.

...

[Diamond] grade item from the [Treasure room].

1) God Stone x 1 (20 million treasure points )

Item name: God stone.

Usage: A rank 9 hero can become a supreme hero after using it.

Information: An item that was even valuable for the beings from the grade 3 worlds.

…..

Unlike the previous sections, there was only one item in the [Diamond] section, and the moment his eyes landed on the item, the mirror showed the information about the item.

'Wait a second.'

However, after seeing the usage of the item, Leo frowned.

'Didn't the old remnant spirit say I can use it break my slave seal? Then why is it not included in its information?'

Nevertheless, Leo still bought the 'God stone' because he knew how valuable it was.
