Abyssal Chronicles - Chapter 1039: The Sound of Wailing

Like every (Isekai) protagonist, I got reincarnated after getting hit by a hyper-speed truck.

That was an empty and dark life anyway, so I was already looking forward to a decent, unknown afterlife.

But... the world had a unique thing in mind.

In this new world, I had parents, amazing ones at that.

My father was a talented mage, and my lovely mother was a sharp and cunning merchant.

Ignoring all of my weirdness, they loved me unconditionally.

This was the life that anyone would love.

Eating and cooking delicious food, practicing archery and magic, and playing with my parents.

Everything was wonderful until... those demons separated us and it left me in a ferocious forbidden forest, just to be eaten alive by beasts.

But dying wasn't even a question.

I will go back… to them.

In short, MC inadvertently created a world, but as the creator of the world, he did not know the world at all. He should have lived here like a fish in the sea with some plug-ins that MCs always have. But now he is even stumped by the bugs in the instant world. Luckily, in this world he has found his shadow guard, or his lover? So the daily adventure is getting not so boring…
