Warrior of Black and White

As the prince of a large kingdom, everyone has high expectations of Rai. A huge reason for this is his bloodline. He is the descendent of 3 legends. A Celestial Mage, a Vampire king, and a Dragon Lord. But, instead of needing years to finish boring subjects like math, reading, and stuff like that, Rai has an easy pass to success. Memories. Oddly enough, Rai has the memories of his 3 legendary ancestors. Even though this is good enough on his own, he has something more strange, a system. With the help of the system, Rai quickly realizes, he is not reincarnated, and he has the memories of his ancestors. Seems like he'll have a nonchallenging life, huh? But Nah. In the memories, all of his ancestors all died the same way... By a strange shadow that devours every strong being... In a world where dragons can leave surrender their species and become humans, where vampires exist, and where a normal person can become a powerful immortal deity.
