In 1368, at the end of July. Bloody scarlet will descend from heaven.

Born in the royal family, Yan Shi has too many things that he is helpless toward.

Doesn’t matter whether he is willing or not, he has already been dragged into the battle for the throne.

But above him there’s a father who detests and rejects him, and below him there are brothers watching him like a tiger watches its prey.
