Need help trying to remember a novels name

[Itami]

Greetings to all, Just trying to remember the name of 2 novels I once read around and if possible a place to read them again.

1) One novel start with the protagonist almost dying when a system issue him a quest to survive and he kind of drags himself to a fountain in a plaza, later on he becomes the king after a long fight with the kingdom system.

2) the other is a protagonist start as a experiment of some super strong entity and he got like 33 siblings that are mutations of different beast bloodlines but he got not and he can absorb them he also unlock the power of the deadly sins and virtues, If my memory does not fail me the name was something to do with Reborn and evolution.

Thanks for the help in advance

I just did a search of the title at LightNovelworld, for your second choice 

Reborn: Evolving from Nothing                          Might be what you are looking for.  Still listed as "ongoing", but no updates for the last 4 years.

Summary

Dorian was out celebrating his college graduation when a car slammed into him, and darkness took hold.

He awoke to find himself in a strange new body, in a strange new world.

One world among 30,000 fantastical worlds, where the mighty rule, where mystic beasts walk the earth, and magic spells warp reality.

For Dorian to survive in these worlds, unfettered and free, living by his strong moral code, he will need great strength.

He must make use of his strange new body and Evolve.
