Great idea with terribly unlikable characters. Would recommend an actual author take the idea and run with it, since translating a Chinese fanfic doesn't get rid of the Chinese DNA.
MC is two-faced and annoying. He willingly chose to join Teach, but he seems to hate his guts just because. Outwardly, the MC will shower Teach with exaggerated flattery, but he'll insult and mock him in his thoughts.
Blackbeard is very out of character. He's been dumbed down significantly, so the MC can take credit for everything he accomplished in canon. Overall, he's portrayed as an agreeable idiot. A dog for the MC to lead around.
The way this has been going, kinda spits in the face of the idea. MC isn't really a vice captain to Blackbeard. He's a snake, using Teach for his own goals, and will likely prey on his downfall later in the story.
