I created a small sphere on the bottom of the sea to prevent larger beings from disturbing me and to protect my newly possessed bodies from the pressure.
I summoned the vampire I kidnapped and possessed him before he could regain conscious. The moment my soul settled down and my NE flooded the body, I felt it overriding the vampires DNA with my own.
It was unlike back when my DNA was being imprinted into my NE and more like combining our DNA and getting rid of any useless genes from the vampire. It could be explained easier like this: New DNA (DNA1) stacked on top of my DNA (DNA2), NE gets rid of any useless stuff from DNA1 and leaves the good part for DNA2, then NE turn the new genes into NE as well and imprints them so that every new body has them as well.
Unless the DNA has too many useful genes that needed to be integrated and transform, it shouldn´t last that long. I was guessing that these two races would only take 2-3 years each to digest.
I needed a few hours to get used to this new feeling of weakness, you could say that I was at my weakest I have been in a long time and this scene was going to happen more often as long as I had to possess new species to get their genes.
I was a little curious about the infamous vampire weakness, so I opened a portal to somewhere in the sky and put my arm through.
Sure enough, I felt extreme pain in my arm and when I pulled it back after a few seconds my arm was gone. I knew that besides access to the darkness of the demon clan the vampires also had eternal life and extreme regeneration to the point where they could survive decapitation in rare cases, so I wasn´t surprised when I saw my arm grow back slowly. It would take weeks maybe even months but it would be back by the time I was back to my old self.

After a few months, I decided to watch the war by sending out a flying eye with basic concealment magic. I could have used game magic to create screens and watch without anyone noticing but I might get to meet and talk to some interesting people that could detect the eye.
And sure enough, not long after I flew the eyes around the battlefield, many beings looked around to see who was watching them but no one spotted the eye yet.
The first one to spot me was actually not someone I expected to meet. It was Gowther and I'm not talking about the doll that joined the sins later, but his creator, the demon Gowther, that brainwashed everyone in the world including the Demon King himself.
Or at least the doll named Gowther which he used to communicate with the world since he was imprisoned for refusing to join the then commandments. We chanted for a bit and I admit I enjoyed the talk more than I thought I would enjoy it, I mean we are basically opposites, he is a pacifist and I am ..., well, you know.
The next people I meet were actually an interesting story. I accidently interrupted a secret date between the soon-to-ne immortal couple and let´s just say Meliodas wasn´t as chill as he would be in the far future.
Not long after meeting the duo, I was finally back to my original body, with a few upgrades of course. I look basically the same except that both my two rows of teeth´s now had fangs. I guess people will now see eight marks on their neck instead of four. Aside from my slight change in appearance I got several other things, my already long lifespan became eternal life (not that it even mattered), my already incredible regeneration became even better, a weaker version of the demon clans darkness and lastly blood drain. The blood drain was more than just being able to life off blood, it allowed me to turn someone into my undead slave when I drain them completely and most importantly, it made the blood I drink taste like the best thing ever.
Sometimes it was sweet and sometimes it was like wine but one characteristic was always the same, the stronger the owner of the blood was the better it tasted.
Well enough explanation and onto the next race, I wanted the proper darkness and not the watered-down version of the vampires. They darkness was not even strong enough to make me proper clothes, it just lacked quality and quantity.
I possessed the demon and started the whole thing all over again.

A/N- it took me over two hours to make this chapter because I constantly got distracted. Also, was the explanation understandable? If you have question feel free to ask.
