(Also I am going to be creating new races purely because I feel like tensura doesn't have enough of them and for time reference one year before Rimuru reincarnated just to give a little bit of a head start)
Daniel was in his home brainstorming ideas for his tensura character but Because of all the stress his heart disease reacted violently and shut down his heart lucky for him reincarnation was real and he was brought into the tensura universe if it weren't for that he probably be in the abyss by now but it's been 24 hours since his reincarnation that only because he was panicking but also because he was trying to figure out all the skills he had and how to use them.
His unique skill optimizer allowed him to optimize certain aspects of skills specifically the downsides but he could also copy and amplify skills but that was only after he obtained the unique skill usurper he could still copy skills through devourer other unique skill which was like a predator but it was a 50-50 chance but the odds were increased thanks to the optimizer unique skill but still there was still a nearly 50% chance he wouldn't get a skill out of it.
And he was restricted to basic skills but honestly were below average he had nothing special physical enhancement shockwave fury and some other skills not only that his magicule count of 11,000 made him a D+ class monster he wasn't even see minus what's the point of being a draconic if you're not even in C tier right now he was Cannon fodder early Rimuru arc type weak it I want to sleep quite sad but then again he understood how can you be a main character and not work away from the ground up unless you were just born overpowered like certain characters(ainz gaool specifically) fine then he will conquer this world from the ground or become something worthy of being recognized by the world and its voice then he'll get the respect that he's earned.
As he was aura farming on a canyon cliff side he noticed something an lesser rock golem moving through the canyon as if it was going somewhere or carrying out an objective it was given might be the case as unless it was an extremely rare circumstance rock golems don't form naturally unless a spirit evolved into one or a rock core was left unattended by a summoner and the Golem became independent as a result there were honestly a lot of different ways golems who's coming to the world it's all depending on what the situation was that you should be scared of.
Now he would be gutsy and try and take it on but even for him that was far above his pay grade not to mention He wasn't even getting paid realistically who to pay a wyvern yeah they have the same gold hoarding tendencies as their superior relatives but they aren't nearly strong enough to secure it for long periods of time so genuinely there's no point in even trying besides he was a lesser wyvern currently any monster beyond C- was way out of his league we have to move on to find other prey that was more his league it's because of his wyvern body he can't fly so he has to traverse the land which is bad for a monster of his caliber He is technically a D+ Class monster the only reason he could be qualified as a C- class is because with the fury skill enhancing all of his abilities he would be at the bottom of the tier list.
As Daniel traveled through the canyons ruff terrain he noticed it a black spider about to finish off a armorsaurus It was the perfect opportunity as he gripped onto the rocks tightly while peering over the edge he lunged forward claws out as the Black spider was prepared to sync it's fangs into the armorsaurus exposed flesh and then Daniel pounced as he opened his mouth and as he slammed onto the spider his claws Easily tore through its exoskeleton and revealed its flesh as he bit into the exoskeleton took a huge chunk out of the black spider but in return he ruptured the poison sac as poison exploded and splattered all over his body he was in so much pain he couldn't see anything and had to keep his eyes closed.
Because he will be blinded so instead of letting go his instincts subconsciously made his claws grip deeper as the black spider made a final attempt shed her egg sack causing her children to flood forward into the world and scatter away suddenly the optimizer came through to save him
Optimizer:«poison resistance acquired»
Immediately the pain didn't sting anymore as he shook The poison he looked down and noticed the spider died from its massive wounds plus blood loss like any normal creature without regeneration would Daniel hesitated extremely heavily eating A massive spider wouldn't be a job on anyone's menu but he had to if he wanted a chance at getting a skill he would have to do it everyone has to make sacrifices once in their life at least.
As he picked up a spider leg he threw it into his mouth and swallowed it whole he immediately wanted to throw it up but he had to keep his stomach so he forcefully swallowed it as optimizer was Analyzing it confirmed its data was incomplete force came to eat more of the black spider as optimizer gained more data the more Daniel at eight finally he got a skill
Optimizer:«poison spit skill acquired due to current Race poison spit will be turned into a poisonous bite to accommodate for the lack of magic power»
Daniel forgot Because he was a wyvern and not a dragon or drake he can't use the magic and he didn't have wings well yeah he had skin he just didn't have the membranes in his wingskins to fly in once so basically he was grounded not only was he magically he can't even fly honestly this was the worst trade off ever even slimes had it better than him The only thing that he had really going for him was the fact that he was almost immune to normal weapons unless they were enchanted by magic or wyvern slayer weapons so basically he was kind of a sitting duck and on the power scale he was trash he was a literally the bottom of the barrel in every way if it wasn't for optimizer that would allow him to obtain skills he would be stuck struggling to gain any sort of power.
