Dear friends, this story takes place on distant Mars, in the Kingdom of Yindu, a wondrous land blessed by the gods.
Legend has it that Bill, the first king of Yindu, was born poor. To support his family, he risked his life and left them behind, traveling with a squid merchant along the Silk Road into the desert. There, in the southern desert, he accidentally glimpsed a miraculous heavenly secret. At the time, a hundred-person caravan was ambushed by a strange and sinister storm. The merciless shifting sands seemed to have been lying in wait for this group of people who had risked everything for money.
