Stone of the Immortal

Earth 3123, everything has changed ever since the great cataclysm that changes the whole planet. It devastated the world and everything seems to have returned to the dark ages. However, humans are not the only ones at the top of the food chain this time around. Fei, or that's what he knows his name is, woke up in this world without a shred of his memory. He is blind but could see in a strange way. He is also very young at the age of 10 or that is what he thinks. Without a past, his only consultation is that... he seems to have fused with a strange stone which turned him into an immortal soul.
