The Nganasan worked swiftly, braving the dangers of the wind and the waves. They had managed to hide twenty to thirty daggers that way.

The areas where they had dug in the daggers were by the water, at the border of the ice layer. With the wind blowing and the waves hitting, it was extremely dangerous to stay in that area. Hence, they had to work fast.

As the wind grew stronger and the waves got taller, the impact on the ice layer created some noise. Ping, ping, it went.

Seeing the daggers were poking out of the surface of the ice, Li Du understood their method of killing the seals.

The seals had a soft stomach. When they moved along, they had to stay on the surface of the ice. Hence, when they crossed the areas with the daggers, they would be quite literally cut up.
