Glacial Pricker Fast/Strong

Bai Yunfei also researched this additional effect. The moment the pricker was thrown out, his soulforce was sucked into it. Its flying speed was indeed more than twice as fast as that of a thrown normal dagger. Its damage was even more impressive as after piercing through a one-meter thick large tree, it could still fly forwards several dozens of meters. Bai Yunfei once carelessly shot it into a mountain wall and afterwards he and Li Chengfeng had to dig as deep as three or four whole meters to take it out.
