Actually, Su Yu has quite a bit of understanding about the memory of the Brutal Evil God.
Back then, Su Yu captured the Brutal Split Mind alive, and after some struggle, brainwashed it using the Power of Nihility, and then used Fear Intelligence to invade it, thereby obtaining the memory of that split mind.
Thus, Su Yu learned a lot of information about the Evil God.
According to the Evil God memory that Su Yu previously obtained, tens of thousands of years ago, or perhaps even earlier, Brutality had already birthed awareness deep within Subspace.
When He first came into being, He was merely a thought of brutality, slumbering in the depth of Subspace.
The rise of humanity, the conquest of the Galaxy, and the wars that affected the entire Galaxy contained an astonishing brutal willpower, awakening the Brutal Evil God from deep within Subspace.
Not only did He awaken, but simultaneously awakened with Him were some even older, more powerful, sinister, and unimaginable beings.
