Zhang Tie went to the sea area in the north of the Waii Sub-Continent with only one target — to gain seven-strength fruits that could greatly increase his fighting strength!
Numerous marine animals and magical beasts were living in the sea area in the north of the Waii Sub-Continent, who were very aggressive and were all mammals. In Zhang Tie's eyes, it was the best hunting ground for him to gain seven-strength fruits.
With some more seven-strength fruits, Zhang Tie was confident that he could improve his precise throwing skill to a terrifying level. Although he had already realized sonic boom, it was not the end; instead, it was just the beginning. A javelin which could fly at the speed of sound would have a completely different destructive strength than that at two times the speed of sound transmission or four times the speed of sound transmission.
