The Eye of Sand was a special weapon, a weapon that could be used by any creature of any race.
After a brief introduction by the Booksmith, Yu Liang immediately understood this weapon.
The Strange Story "Human" had mastered the Book of Sand through special means, and combined with the ability of the Raiders Group to transmit memories regardless of space-time causality, the Eye of Sand had become, to a certain extent, a weapon of destruction that obeyed their commands.
All that was required was to send a certain number of sacrificial Strange Story "Humans" to a designated location, and then at a future moment, transfer memories of the Book of Sand into the memory banks of these Strange Story "Humans". This would attract the Eye of Sand to the location.
