The Dragon Tooth Soldiers were somewhat startled when five of their number suddenly disappeared.
They were usually the ones killing others; no one had ever killed them.
The inexplicable disappearance of their companions made the Dragon Tooth Soldiers tense.
The nearly three hundred Dragon Tooth Soldiers immediately raised their Bone Shields and began charging forward.
They understood that this was not the time to wait around. They had to reach the enemy formation as quickly as possible.
They had not even made contact with the undead yet and had already lost so many men. That was not good news.
So the Dragon Tooth Soldiers ignored the Hundred-Headed Giant Dragon behind them and charged forward with their Bone Shields raised.
At this moment, the nine thousand Archer Units launched another attack.
Nine thousand arrows fell upon the Dragon Tooth Soldiers like rain.
However, compared to the Arrow Tower Hunter's attacks, these arrows were truly far too weak.
The Dragon Tooth Soldiers swept their Bone Shields sideways, knocking the arrows away.
After the rain of arrows, not only did they not retreat, they charged several hundred meters farther ahead.
However, the Dragon Tooth Soldiers did not notice that another seven or eight of them had vanished during their charge.
They had been sent into the Frost Mirror Ghost Prison.

There was a piece of information recorded there that Gu Xi had nearly overlooked.
