The endless western desert border stretches thousands of miles, rooted with thousands of outposts.
After hundreds of years, many of these outposts have been abandoned. The few remaining ones have lost their original functions, becoming shelters against the elements for their residents.
On this day, groups of giants appeared on the barren sandy land.
One by one, the sand giants rose from the ground and advanced toward Yellow Sand City and other frontier cities on the western desert border. Their first stop was the abandoned or ineffective outposts.
"What are those things?" A woman drying clothes in her fenced yard exclaimed as she saw the rolling sand on the horizon, witnessing a boundless wall of sand moving sideways toward them.
Upon hearing the woman's cries, the man instinctively picked up his weapon and stepped out of the house. As soon as he did, he saw countless tall sand giants heading their way.
