As for Brother San Shui losing face and feeling humiliated, Elder Long didn't really care too much. After all, who can stay invincible forever? Occasionally losing face might actually be a good thing.
Back in the day, even Han Xin could endure the humiliation of crawling between someone's legs, which pushed him to rise above and achieve greatness. So, Brother San Shui might not necessarily fail to mature and grow from this incident. Perhaps, one day, he could even take Elder Long's place!
This was Elder Long's perspective. Although he wasn't really serious when he entertained this thought, little did he know that Brother San Shui truly did grow mature because of this incident. Eventually, he unified Hong Kong Island's underground forces, not only inheriting Elder Long's position but even surpassing him to seize a much larger empire.
