Achilles wasn't only the Greek's champion and the most powerful hero of the entire Trojan War. He was invincible on the battlefield, unstoppable even. And he managed to kill Hector, the bravest warrior of Troy, causing the long-stalemate war to lean towards Greece's side. He was known as a demigod hero powerful enough to change the tide of battle. Unfortunately, he blasphemed against Apollo, son of Zeus, and killed by Hector's younger brother, Paris. Under Apollo's guidance, Paris' Arrow accurately hit the only weakness on Archilles' body, his ankle.
This arrow was now in Zhang Heng's hand.
[Paris' Arrow]
[Grade: D]
[Effect: Once the arrow leaves the bow, it automatically heads for the target's weakness.]
