The Sea God initially stared at him, creating pressure on him, but later when he used his energy to resist, he fell right into the trap.
All along, it was just Blacky fighting against himself; the Sea God merely guided him, making him think he was insurmountable and invincible.
Blacky finally realized it was too late by now, and he truly fell into the Sea God's perfect Illusion Realm.
He began to regret it, thinking that if he hadn't actively provoked the Sea God at that time, or even if he did provoke him, as long as he wasn't so afraid and didn't exert his energy to resist, things wouldn't be like this now.
Blacky is absolutely clear about his current situation, being on the brink of life and death is not an overstatement.
There are currently two paths: one is to beg the Sea God for mercy, the other is to find the flaws in the dream himself.
Given Blacky's previously exhibited strong survival instinct, he did not disappoint and began to beg the Sea God for mercy.
