Subsequently, this wisp of essence blood stood still in the void, and Zhou Yan began to analyze the structure and essence of this drop of blood with his powerful sensing ability.
This drop of essence blood seemed not to differ from that of ordinary cultivators, with nothing strange about it.
But when the blood was broken down to the finest parts, the white cells inside were like unique worlds.
