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
