Blood and Qi - Anthony Alves

John, a vampire living for near six thousand years, has gone by many names in his long life. Warrior, king, god: he's done and seen it all. He may look very young, but he is by far the oldest of the vampires, the pinnacle of power on Earth. Such great age can also be a curse, as his mind has not kept up with the regeneration of his body, and he now struggles to even remember his own name.

That is until powerful beings called the ascended come to Earth and remove a shield blocking our solar system from the Tree of Life. John is healed, and his mind restored, and he feels as fresh as the day he was turned so long ago, and he is ready to learn this new way of gaining power, this self-cultivation, and defend his world. But he's no longer the apex predator and the top of the heap. A high ascended wants his head, and armies of demons, dark ones, and g'athu stand in his path.

John has accumulated many skills throughout his life, and with the NCS giving him knowledge and guidance on the ways and techniques of self-cultivation; he is determined to fight back. Joined by the strange and beautiful Amber, a woman as extraordinary as any vampire, the source of many old tales herself, John endeavours to grow in might.

It's a race for survival, and if humans manage to endure the current invasion, their only prize will be a far deadlier one.

Vampires are unknown throughout the many universes, could John and his kin be the reason Earth was kept from the Tree of Life?
