Immortal's Journey with the Goddess

Kaiser, an orphan with modest expectations, thought life was simple. You study, get a job, and eventually start a family in a peaceful yet fiercely competitive world. As an ordinary student, he went with the flow—until his high school graduation arrived. That’s when everything changed. Due to the incompetence of the gods, all the graduates were summoned to another world, each blessed with unique gifts. But for Kaiser, things took a strange turn. "Why on earth do I have to take care of the very goddess who caused this mess?!" What I cooked: -An MC that doesn't die—don't expect him to think and deal with situation like normal person would. If the goal is getting down the mountain fast, he'll literally jump down. But he's not stupid... Just different. -Comedy—better not be drinking or eating when reading this. Btw, you might also cry, be warned.  -Weak to strong... I mean, he literally can't die, so even though he's not blessed with talents, despised by fate, and chased by misfortune. He had no choice but to get stronger.  -Worlds and creatures that came from my dreams and nightmares... Mostly, nightmares.  Read chapter 1; https://www.royalroad.com/fiction/95652/immortals-journey-with-the-goddess/chapter/1844492/chapter-1-graduation-from-normality Give it a try, thanks!
