章節 431: A Trouble from a Familiar Person

After digesting 7 seven-strength fruits of iron-teeth hyenas, a fruit of brilliance and a fruit of judgment, Zhang Tie came out of the Castle of Black Iron on the 7th day.

Seven-strength fruit of iron-teeth hyena was the most powerful seven-strength fruit that Zhang Tie had ever eaten. As a fruit of LV 1 living being, the total of its seven strengths were far more than that of wild-wolf seven-strength fruit and demon-rat seven-strength fruit. After completely digesting the 7 seven-strength fruits of iron-teeth hyenas, Zhang Tie felt that his explosiveness increased by more than 40%.

This was a huge, terrifying progress. Precisely, he could throw his javelin at a speed of 1024 m/s, which was 3 times more than the speed of sound transmission in the air, instead of 728 m/s, which was only greater than 2 times the speed of sound transmission in the air. Its maximal effective lethal range also surpassed 1000 m.
