บท 867: The dwarf's first achievement (1)

Although it was called a secret weapon, it was actually not that much of a secret. The secret weapon that Zhao Hai gave to the elves was actually the blood Thunder bead! The bows and arrows used by the elves were mainly used to shoot stone bullets. No one knew how they did it. Not only could they shoot round stone eggs, but they could also shoot very accurately. It could be said that they were the best on the continent.

Because of this, Zhao Hai had prepared many blood Thunder beads for the elves. If the elves used bows and arrows to shoot the blood Thunder beads, they would be quite powerful.
