Redd took a moment to take in the information he was given. The most important thing seemed to be that evolution was not simply useful in obtaining the blood of stronger species, but that it was required for his body to handle such precious blood. The next that entered his mind was that while this creature seemed very powerful, he was an artificial creature. Even if he had blood, it would be unnatural, and for some reason it made it seem unappealing on a deeper level. 

It seemed that the ancient being suggested combat as a logical course of action. Redd was not opposed to this if was a way to further this goals, and combat did have the added benefit of blood shed. 

The final thought was that vampiric evolutions would displease humans, however he already seemed to have this idea. However, humans was just a means to an end, once he had evolved into a form stronger then them, he would no longer have use of them. Though, for the time being, perhaps the adventurer's guild could be of service.
