我终究会称霸天下
[wŏ zhōng jiū huì chēng bà tiān xià]
Translating to 'I Will Finally Dominate The World,' the nickname expresses ambition and determination. A sense of eventual success and power. While it might be hyperbole, it showcases someone confident in their abilities or with big aspirations, regardless if it's in literal domination, career ambitions, or self-development.
