The sun was setting when the boy's heart sounded a danger signal.

Five minutes later, the boy saw two horsemen waiting ahead of them.

Before he could say anything to the alchemist, the two horsemen had become ten, and then a hundred.

And then they were everywhere in the dunes.
最后整个沙丘都布满了骑兵。
They were tribesmen dressed in blue, with black rings surrounding their turbans.
这些骑兵身着蓝衣，头巾用黑色头箍套住。
Their faces were hidden behind blue veils, with only their eyes showing.
蓝布罩在脸上，只露出两只眼睛。
Even from a distance, their eyes conveyed the strength of their souls. And their eyes spoke of death.
虽然离得很远，他们的眼睛仍显示出了心灵的力量，那里流露出的是杀气。
