Fisher Tiger was a legendary figure. His feat of climbing the Red Line with his bare hands and freeing countless slaves was still being passed down even now. Quite a few members of the Revolutionary Army had been rescued by him back then; Koala was merely one representative.
If he appeared again and raised the call, it would be enough to deal a fatal blow to the prestige of the World Government and the Navy. The World Government and the Navy had always denied the existence of slaves, but if Fisher Tiger appeared, they would have no way to deny it. The slave trade had always been an indelible stain on the World Government and the Navy.
The reason Shen Fei's earlier leaflet campaign had caused so many Marines to defect was precisely this. The slave trade was something only the Navy's high command knew about; ordinary Marines had no idea. Once such matters were publicized, military recruitment would naturally suffer the greatest impact. Ordinary people might not be able to fight the World Government and the Navy, but they could simply choose not to become Marines.
The loss of large numbers of ordinary Marine soldiers and the difficulties in recruitment had forced the World Government to conscript soldiers from its member nations. This was yet another major burden for those nations.
"I'll persuade her."
Fisher Tiger could suppress the hatred for humans in his heart, but he could not suppress his hatred for the World Government. Being saved by a human like Shen Fei had actually made him very unhappy. If he had wanted to, he could have survived back then, but Shen Fei had ultimately persuaded him by invoking Fish-Man Island.
Fisher Tiger might not have cared about his own life, but he cared deeply about his people
