Memories After Freezing

This novel is a trailer. The plot of the novel is about a strange boy and his biological brother in ancient times. Because both of them were different from others since they were young, they had super worldly abilities. His brother wants to destroy the entire earth for his own plan. In order to stop him, his brother was frozen in an ice cellar by a strong cold current after World War I. Hundreds of years later, modern humans discovered that after research by scientists and the medical community, this man could be saved. After the rescue, the story is unknown. Please give me some advice on how to fantasize. Thank you. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
